  As shown in FIGS. 1 and 2, a game panel 30 for notifying the player of the game state is provided on the upper side of the central portion of the front door 12. In the game panel 30, three vertically long display windows 31L, 31M, and 31R are formed side by side. The display windows 31L, 31M, and 31R are made of a transparent or translucent material, and the inside of the slot machine 10 is visible through the display windows 31L, 31M, and 31R. The display windows 31L, 31M, and 31R may be combined into a single display window.

  As shown in FIG. 3, the inside of the housing 11 is vertically divided into two by a partition plate 40, and a reel unit 41 constituting variable display means is attached to the upper portion of the partition plate 40. The reel unit 41 includes a left reel 42L, a middle reel 42M, and a right reel 42R each formed in a cylindrical shape (annular shape). Each of the reels 42L, 42M, and 42R only needs to be configured as an endless belt, and is not limited to a cylindrical shape (annular shape). Each of the reels 42L, 42M, and 42R is rotatably supported so that the central axis thereof is the rotation axis of the reel. The rotation axes of the reels 42L, 42M, and 42R are arranged on the same axis extending in the substantially horizontal direction, and the reels 42L, 42M, and 42R have a one-to-one correspondence with the display windows 31L, 31M, and 31R. . Therefore, a part of the surface of each reel 42L, 42M, 42R can be visually recognized through the corresponding display windows 31L, 31M, 31R. Further, when the reels 42L, 42M, and 42R rotate forward, the surfaces of the reels 42L, 42M, and 42R are projected as if moving from top to bottom through the display windows 31L, 31M, and 31R.

  As shown in FIG. 5, the reels 42L, 42M, and 42R are connected to stepping motors 61L, 61M, and 61R, and the reels 42L, 42M, and 42R are driven by the stepping motors 61L, 61M, and 61R. Are configured to be able to rotate individually, that is, independently of each other. Since these reels 42L, 42M, and 42R have the same configuration, the left reel 42L is illustrated as a representative of each reel in FIG.

  The left reel 42L includes a cylindrical skeleton member 50 that forms a cylindrical cage, and a belt-like belt wound endlessly on the outer peripheral surface thereof. And it is affixed on the cylindrical skeleton member 50 through a pair of seal parts formed along the both sides of the long side of the belt so as to maintain the wound state. A large number of symbols as identification information are printed at equal intervals on the outer peripheral surface of the belt.

  As shown in FIG. 5, the left reel stepping motor 61 </ b> L is fixed to the side surface of the motor plate 53 arranged in an upright state in the reel unit 41 (FIG. 3) with screws 54. The motor plate 53 is provided with a reel index sensor (rotational position detection sensor) 55 in which a light emitting element 55a and a light receiving element 55b are held at a predetermined interval. On the other hand, the base end portion 56b of the sensor cut bun 56 extending in the radial direction is fixed to the boss reinforcing plate 52 integrated with the left reel 42L by a screw 57. The front end portion 56a of the sensor cut bun 56 is bent at a substantially right angle and is positioned so that it can pass between both elements 55a and 55b of the reel index sensor 55. Each time the left reel 42L makes one rotation, the reel index sensor 55 detects the passage of the tip end portion 56a of the sensor cut bun 56, and outputs a detection signal to the main controller 130 described later each time the detection is made. Therefore, main controller 130 can confirm and correct the angular position of left reel 42L for each rotation based on this detection signal.

  The stepping motor 61L is set to rotate once by giving, for example, a drive signal of 504 pulses (also referred to as an excitation signal or an excitation pulse; the same applies hereinafter), and the rotation position of the stepping motor 61L, that is, The rotational position of the left reel 42L is controlled.

  On each belt of each of the reels 42L, 42M, and 42R, a plurality of, specifically, 21 symbols are drawn in the long side direction (circumferential direction). Therefore, 24 pulses (= 504 pulses ÷ 21 symbols) are required to switch from one symbol to the next symbol at a predetermined position. Based on the number of pulses from when the detection signal of the reel index sensor 55 is output, it is possible to recognize which symbol is visible from the display window 31L, or to visually recognize an arbitrary symbol from the display window 31L. It is possible to perform control to achieve a proper state.

  Of the symbols attached to the reels 42L, 42M, and 42R, the number of symbols that can be visually recognized through the display windows 31L, 31M, and 31R is mainly determined by the vertical length of the display windows 31L, 31M, and 31R. Is limited to a predetermined number. In this embodiment, three reels are provided. For this reason, when all the reels 42L, 42M, and 42R are stopped, 3 × 3 = 9 symbols are visible to the player.

  Here, the symbols attached to the reels 42L, 42M, and 42R will be described. FIG. 6 shows a symbol array drawn on the belt wound around each of the left reel 42L, the middle reel 42M, and the right reel 42R. As shown in the figure, each of the reels 42L, 42M, and 42R is provided with 21 symbols in a row. Numbers 1 to 21 are assigned to the respective reels 42L, 42M, and 42R, but these are given for convenience of explanation and are not actually attached to the reels 42L, 42M, and 42R. . However, in the following description, the number is used for explanation.

  As the symbols, there are a “7” symbol (for example, the left belt 20th) and a “youth” symbol (for example, the left belt 19th) as the first special symbol for shifting to the big bonus game. In addition, there is a “BAR” symbol (for example, the 14th left belt) as the second special symbol for shifting to the regular bonus game. Further, there is a “replay” symbol (for example, the eleventh left belt) as a third special symbol for shifting to the replay game. In addition, a “watermelon” symbol (for example, the left belt ninth), a “bell” symbol (for example, the left belt eighth), and a “cherry” symbol (for example, left) as the small character symbols from which the small character is paid out. Belt 4th). In the belts wound around the reels 42L, 42M, and 42R, the number and arrangement order of various symbols are completely different.

  Each reel 42L, 42M, 42R of the reel unit 41 is an example of variable display means for variably displaying the identification information, and constitutes a main display unit. However, the variable display means may have other configurations. For example, other mechanical reel configurations such as a type in which the belt is rotated instead of rotating may be used, and instead of or in addition to the mechanical reel configuration, a liquid crystal display or a dot matrix display It is also possible to provide a display that variably displays the identification information by electrical display such as, and in this case, it is possible to provide a variety of display forms.

  In addition, backlight devices 100L, 100M, and 100R that illuminate the belts of the reels 42L, 42M, and 42R from the inside are disposed inside the reels 42L, 42M, and 42R.

  As shown in FIG. 7A, these backlight devices 100L, 100M, and 100R are attached to the respective reels 42L, 42M, and 42R in a one-to-one correspondence with the left backlight device 100L and the middle backlight. The apparatus 100M includes a right backlight apparatus 100R. As described above, each of the backlight devices 100L, 100M, and 100R includes the game panel 30 on the side surface of each of the motor plates 53L, 53M, and 53R arranged in correspondence with the reels 42L, 42M, and 42R. Is attached to the side. And each backlight apparatus 100L, 100M, 100R is arrange | positioned in the same position seeing to an up-down direction. FIG. 7A is an enlarged perspective view showing the periphery of the reel unit 41 in a state where the reels 42L, 42M, and 42R are removed. Moreover, FIG.7 (b) used by the following description is a front view of the left backlight apparatus 100L. In FIG. 7B, since the backlight devices 100L, 100M, and 100R all have the same structure, the left backlight device 100L is representatively illustrated.

  As shown in FIG. 7B, the left backlight device 100L has a box shape with the front side opened, and the length in the vertical direction and the length in the horizontal direction are substantially the same as those of the display window 31L (FIG. 1). A base 101L is provided. In the base 101L, two partition walls that divide the opening region are formed at equal intervals, so that the first opening region 102L, the second opening region 103L, and the third opening region 104L are formed in an upper stage, a middle stage, and a lower stage, respectively. It has a structure that is lined up. When the front door 12 is closed, the opening regions 102L, 103L, and 104L are arranged behind the positions corresponding to the upper, middle, and lower stages of the display window 31L. Specifically, the first opening area 102L is arranged behind the upper stage of the display window 31L, the second opening area 103L is arranged behind the middle stage of the display window 31L, and the third opening area 104L is arranged in the display window 31L. It is placed behind the lower stage. The opening front of the first opening region 102L is slightly upward, and the opening front of the third opening region 104L is slightly downward. Accordingly, the side surface of the base 101L has an arc shape that bulges toward the game panel 30 side.

  In each of the opening regions 102L, 103L, and 104L, four backlights 105 each made of a light emitting diode are disposed so as to stand forward. Two backlights 105 in each of the opening regions 102L, 103L, and 104L are arranged in two upper and lower rows with a predetermined interval, and the backlights 105 in each row are horizontal with a predetermined interval. Are lined up like That is, the left backlight device 100L includes a first line L1 that is an upper row of the first opening region 102L, a second line L2 that is a lower row, and a third line that is a row above the second opening region 103L. L3 and the fourth line L4, which is the lower row, the fifth line L5, which is the upper row of the third opening region 104L, and the sixth line L6, which is the lower row, total 6 in the vertical direction across the partition wall. There will be a line of backlight 105 in the column. The middle backlight device 100M and the right backlight device 100R also have a total of six lines of the backlight 105. As described above, the backlight devices 100L, 100M, and 100R are viewed in the vertical direction. Since they are arranged at the same position, the lines L1 to L6 of the backlight devices 100L, 100M, and 100R are located on the same line. That is, the line L1 is a line that horizontally connects a total of six backlights 105 arranged in a row above the first opening regions 102L, 102M, and 102R of the backlight devices 100L, 100M, and 100R. Become. The same applies to the other lines L2 to L6. Each backlight 105 is controlled for each of the lines L1 to L6. Accordingly, the backlight 105 is turned on and off for each of the lines L1 to L6.

  When the backlights 105 on the lines L1 to L6 are turned on, different positions of the belts of the reels 42L, 42M, and 42R are illuminated from the rear. As described above, each of the bases 101L, 101M, and 101R is divided into three opening regions 102 to 104 by the partition walls. Therefore, when the backlight 105 on the first line L1 and the second line L2 is turned on, only the inner surface of the belt near the position corresponding to the upper stage of the display windows 31L, 31M, 31R is illuminated, and the display window 31L , 31M, 31R, the inner surface of the belt near the positions corresponding to the middle and lower stages is not illuminated. This is the same when the backlight 105 on the other lines L3 to L6 is turned on. As described above, since the belt is formed of a material that can transmit the irradiated light to some extent, when the belt is illuminated from the rear by the backlight 105, the light transmitted through the belt is displayed on the display window 31L, It is visually recognized by the player through 31M and 31R. Further, when the reels 42L, 42M, and 42R are rotating, the symbols attached to the belt passing in front of the lit backlight 105 are emphasized.

  As shown in FIG. 1, the game panel 30 has a combination line of 3 display windows 31L, 31M and 31R, 3 in parallel in the horizontal direction and 2 in the diagonal direction. Is attached. Of course, the maximum number of combined lines may be 6 or more, or less than 5, and the maximum number of combined lines may be changed according to a predetermined condition. Corresponding to each of these combination lines, effective line display sections 32, 33, and 34 are provided on the left side as viewed from the front of the display windows 31L, 31M, and 31R. The first effective line display unit 32 is notified by lighting or the like when the central horizontal line (center line) of the combination lines is activated. When the upper and lower horizontal lines (upper line and lower line) of the combination lines are activated, the second effective line display unit 33 is displayed and notified by lighting or the like. The third effective line display unit 34 is notified by lighting or the like when a pair of diagonal lines (downward right line and upward right line) of the combination lines is activated. A winning is awarded when the symbols are stopped in a predetermined combination on the activated combination line, that is, on the activated line, and a predetermined medal payout process, a transition process to a specific game, and the like are executed.

  Here, the payout number regarding each symbol when winning is explained. Regarding the small role design, when the “Watermelon” design is aligned with the left, middle and right on the active line, 15 medals are paid out. When the “Bell” design is aligned with the left, middle and right on the effective line Pays out 8 medals, and when the “cherry” symbol on the left reel 42L stops on the active line, 2 medals are paid out. That is, the “cherry” symbols of the middle reel 42M and the right reel 42R are irrelevant to the medal payout. In addition, for the “cherry” symbol, the medal payout is performed regardless of the combination with other symbols, and therefore, a plurality of effective lines of the left reel 42L overlap (specifically, the upper or lower row) with “ When the “cherry” symbol is stopped, medals are paid out by multiplying the number of overlapping active lines. As a result, in this embodiment, four medals are paid out.

  As for other symbols, when the “7” symbol or “youth” symbol, which is a combination of the first special symbol (big bonus symbol), is aligned with the left, middle and right on the active line in the same symbol The 15 medals are also paid out when the “BAR” symbol which is a combination of 15 medal payouts and the second special symbol (regular bonus symbol) is aligned with the left, middle and right on the active line. In the present embodiment, for example, a case where the “7” symbol and the “cherry” symbol are established simultaneously may occur, but in this case, 15 medals are paid out. This is because the upper limit number for one medal payout is set to 15.

  Further, when the “replay” symbol, which is the combination of the third special symbol, is aligned with the left, middle, and right on the active line, the medal payout is not performed. In other cases, that is, when the “cherry” symbol of the left reel 42L does not stop on the active line and the same symbols as the left, middle, and right are not aligned on the active line, no medal payout is performed.

  As shown in FIG. 1, a start lever 71 operated to start rotation of the reels 42L, 42M, and 42R all at once (not necessarily simultaneously) is provided on the lower left side of the game panel 30 as shown in FIG. . The start lever 71 constitutes start operation means or start operation means operated to start rotation of the reels 42L, 42M, and 42R, that is, to start variable display. The start lever 71 is a lever that is pushed by the hand when the player starts the game, and automatically returns to the original position after the hand is released. When the start lever 52 is operated while a medal is inserted, the reels 42L, 42M, and 42R start to rotate all at once.

  On the right side of the start lever 71, button-like stop switches 72, 73, and 74 that are operated to individually stop the rotating reels 42L, 42M, and 42R are provided. The stop switches 72, 73, and 74 are respectively disposed below the display windows 31L, 31M, and 31R corresponding to the reels 42L, 42M, and 42R to be stopped. The stop switches 72, 73, 74 constitute stop operation means that are operated to stop variable display based on the rotation of the reels 42L, 42M, 42R. Each of the stop switches 72, 73, 74 can be stopped when each of the reels 42L, 42M, 42R is rotated at a constant speed. During such a state, the lamps (not shown) are turned on and stopped. It is notified that the operation is possible, and is turned off when the rotation stops.

  On the lower right side of the display windows 31L, 31M, 31R, a medal inserter 75 for inserting medals as an investment value is provided. The medal inserter 75 constitutes an input means for inputting the investment value. If attention is paid to the point that the medal insertion device 75 involves an operation of directly inserting a medal by the player, it can be said that the medal insertion device 75 constitutes a direct input means for directly inputting the investment value.

  As shown in FIG. 3, the medals inserted from the medal inserter 75 are guided to either the storage passage 81 or the discharge passage 82 by the selector 84 provided on the back surface of the front door 12.

  FIG. 8 is a diagram showing the internal structure of the selector 84. The two-dot chain line in the figure indicates the medal passage route for easy understanding. The selector 84 is formed with a guide passage 85 for guiding medals inserted from the medal inserter 75 to the storage passage 81. The guide passage 85 is formed in a curved line that draws an arc from the upper end to the lower right in the drawing so that medals can pass in one row. More specifically, the selector body constituting the selector 84 is provided with a protrusion 85a protruding toward the front side of the figure, and a guide passage 85 is formed along the protrusion 85a. Thereby, the medal that has reached the guide passage 85 flows in the downstream direction so as to roll on the ridge 85a.

  The medal passage switching member 83 includes a passage switching piece 83a that is provided in the upstream portion of the guide passage 85 and can be moved in and out of the guide passage 85, and a solenoid (not shown) for operating the passage switching piece 83a. doing. When the solenoid is not excited, the passage switching piece 83a protrudes into the guide passage 85, and the flow of medals to the storage passage 81 is obstructed. As a result, the medal falls downward so as to get over the protrusion 85 a and is guided to the discharge passage 82. Further, the passage switching piece 83a is sunk outside the guide passage 85 when the solenoid is excited. Thereby, the medal flows along the guide passage 85 and is guided to the storage passage 81.

  On the downstream side of the passage switching piece 83a, a first inserted medal detection sensor 86 and a second inserted medal detection sensor 87 for detecting the passage of medals are arranged close to each other so as to be arranged upstream and downstream of the guide passage 85. (At least one time is set to a close state where the same medal is detected at the same time). When the solenoid of the medal path switching member 83 is not energized, the medal falls downward from the middle of the guide path 84, so that the inserted medal detection sensors 86 and 87 do not detect the passage of the medal. On the other hand, when the medal passage switching member 83 is energized with solenoid, the inserted medal detection sensors 86 and 87 sequentially detect the passage of medals.

  Then, the medal guided to the storage passage 81 is guided to the hopper device 91 accommodated in the housing 11. On the other hand, the medal guided to the discharge passage 82 is guided to the medal tray 18 from the medal discharge port 17 provided in the lower front portion of the front door 12 and returned to the player.

  As shown in FIGS. 3 and 4, the hopper device 91 serving as a payout means for giving a medal to a player includes a storage tank 92 for storing a medal and a payout device 93 for paying out a medal to the player. Yes. The payout device 93 rotates a medal payout rotating plate (not shown) to discharge the medal to the opening 94 provided in the central right part of the discharge passage 82 and to the medal tray 18 through the discharge passage 82. To come out. Further, a reserve tank 95 is provided on the right side of the hopper device 91 in order to avoid storing a predetermined amount or more of medals in the storage tank 92. A guide plate 96 for discharging medals from the storage tank 92 to the reserve tank 95 is provided inside the storage tank 92 of the hopper device 91. Therefore, when medals are stored more than the height at which the guide plate 96 is provided, the medals are stored in the reserve tank 95 via the guide plate 96.

  A button-like return switch 76 (FIG. 1) is provided below the medal inserter 75. The return switch 76 is a switch that is pressed when a medal inserted into the medal inserter 75 is jammed in the selector 84. When this switch is pressed, the selector 84 is mechanically operated to operate the selector 84. The medals packed in 84 are returned from the medal discharge port 17.

  On the lower left side of the display windows 31L, 31M, 31R, as shown in FIG. 1, a button-shaped first credit insertion switch 77 is provided for inserting three credited virtual medals as investment values at a time. ing. Further, on the left side of the first credit insertion switch 77, a second credit insertion switch 78 and a third credit insertion switch 79 are provided as button switches smaller than the switch 77. The second credit insertion switch 78 is for inserting two credited virtual medals at a time, and the third credit insertion switch 79 is for inserting one virtual medal. Each of the credit insertion switches 77 to 79, together with the medal insertion device 75, constitutes an input means for inputting an investment value. Further, if the medal insertion device 75 is accompanied by an operation of directly inserting a medal by the player, each credit insertion switch 77 to 79 is only accompanied by an operation of insertion of a virtual medal based on the storage memory. It can also be said that it constitutes an indirect input means for indirectly inputting the investment value.

  Note that the first credit insertion switch 77 has a built-in lamp as a light emitting member (not shown) in order to notify that the maximum number of medals that can be inserted per game (three) has not been reached. The lamp is turned on when the switch operation of the first credit insertion switch 77 is valid and prompts the operation of the switch 77. However, when there is no credited virtual medal or three medals have already been inserted. It is turned off under the circumstances. Here, instead of the above-described lighting, the player may make it easier to understand the prompt for medal insertion by blinking.

  A button-like changeover switch 80 is provided on the left side of the start lever 71. The change-over switch 80 is configured to be a toggle type that is turned on when pressed once, turned off when pressed again, and turned on / off every time the pressing operation is performed. The changeover switch 80 is operated to change the handling format of inserted medals inserted in the medal inserter 75 more than necessary, or acquired medals returned to the player as a result of a predetermined game.

  When the change-over switch 80 is in the ON state, the “credit mode” is set so that surplus inserted medals up to a predetermined maximum value (for example, 50 medals) and winning medals are stored and stored as credit medals. " When the changeover switch 80 is in the OFF state, the “direct mode” is set so that surplus inserted medals and winning medals are paid out as actual medals. If there is a credit medal when the credit mode is switched to the direct mode, the corresponding credit medal is paid out as an actual medal. Thus, the player can execute the game in a format according to his / her preference by switching between the credit mode and the direct mode. The changeover switch 80 constitutes a changeover operation means for changing over the input value and game value handling formats. Further, if paying attention to the function of paying out a credited virtual medal as an actual medal, it can be said that the changeover switch 80 constitutes a settlement operation means for actually paying out the stored game value. In addition to being configured to switch between the “credit mode” and the “direct mode” by operating the changeover switch 80, the virtual medal stored and stored is paid out when the changeover switch 80 is operated by always setting the “credit mode”. It may be made to function as only a settlement switch.

  Below the display windows 31L, 31M, and 31R of the game panel 30, a remaining number display unit 35 that displays the number of medals that are activated and stored in the credit mode, and a special game state such as a big bonus or a regular bonus are displayed. In this case, for example, a game number display unit 36 for displaying the number of remaining games and an acquired number display unit 37 for displaying the number of acquired medals are provided. Although these display parts 35-37 are comprised by the 7 segment display, it is naturally possible to substitute by a liquid crystal display etc. FIG.

  Here, a procedure for betting medals will be described. In both the direct mode and the credit mode, a bet is placed when a medal is inserted from the medal inserter 75 at the start of the game.

  That is, when the first medal is inserted into the medal inserter 75, the first effective line display unit 32 is turned on, and the corresponding center line becomes the effective line, and the second medal is the medal inserter. When the number 75 is inserted, the second effective line display section 33 is turned on, and a total of three combination lines including an upper line and a lower line corresponding to the second effective line display section 33 become effective lines, respectively, and the third medal is a medal. When inserted into the input device 75, the third effective line display unit 34 is further turned on, and all five combination lines including a pair of diagonal lines corresponding thereto become effective lines.

  When four or more medals are inserted into the medal inserter 75, surplus medals exceeding three are switched to the discharge passage 82 by the selector 84 if the current mode is the direct mode. It is returned from the outlet 17 to the medal tray 18. On the other hand, in the credit mode, it is stored inside the slot machine, and the number of stored sheets is displayed on the remaining number display unit 35. An upper limit number is determined for the number of stored sheets (for example, 50), and when a medal exceeding the number is inserted, it is returned from the medal discharge port 17 to the medal tray 18.

  In addition, when a game is played in the credit mode and the number of stored items is displayed on the remaining number display unit 35, the virtual number is displayed even when any of the first to third credit insertion switches 77 to 79 is pressed. A medal has been inserted and the player bet.

  When the third credit insertion switch 79 is pressed, the numerical value displayed on the remaining number display section 35 is decremented by one as a virtual medal is inserted, and the first effective line display section 32 is displayed. Illuminates and the center line becomes the active line. When the second credit insertion switch 78 is pressed, two numerical values displayed on the remaining number display unit 35 are decremented as two virtual medals are inserted, and the first valid line display unit 32 and The second effective line display section 33 is lit and a total of three combination lines become effective lines. When the first credit insertion switch 77 is pressed, three numerical values displayed on the remaining number display unit 35 are decremented as three virtual medals are inserted, and all the effective line display units 32 to 32 are decremented. 34 lights up and a total of five combination lines become effective lines.

  In addition, when the virtual medal to be inserted when any of the first to third credit insertion switches 77 to 79 is pressed is not stored, for example, when the display of the remaining number display unit 35 is 2, the first For example, when the credit insertion switch 77 is pressed, all the values in the remaining number display section 35 are decremented to 0, and a bet is made for the virtual medals that can be inserted.

  In the upper part of the front door 12, there are provided an upper lamp 13 that lights up or flashes as the game progresses, and an auxiliary display unit 15 that gives various information to the player. In the present embodiment, the auxiliary display unit 15 is configured by a liquid crystal display for the purpose of diversifying display contents and increasing the display effect. However, other displays such as a dot matrix display may be used. Good. The auxiliary display unit 15 is for executing various display effects as the game progresses, and it can be considered that the game by the reels 42L, 42M, and 42R is caused by the main display unit. This is referred to as an auxiliary display unit 15. In addition, a pair of left and right speakers 14 that play various sound effects as the game progresses and notify the player of the gaming state are provided at the lower part of the front door 12. A sub-control device 111 for driving the upper lamp 13, the speaker 14, the auxiliary display unit 15, the backlight 105, and the electric motor 223a is provided on the back surface of the auxiliary display unit 15. Note that the positions and number of the upper lamps 13 and the speakers 14 are not particularly limited to those described above.

  A lower plate 16 on which a model name, a character related to a game, and the like are displayed is mounted above the medal tray 18. In addition, an ashtray 19 that can be reversed to the lower side on the front side is provided on the left side of the medal tray 18.

  As shown in FIG. 3 or FIG. 4, a power supply box 121 is provided on the left side of the hopper device 91 inside the housing 11. The power supply box 121 includes a power switch 122, a reset switch 123, a setting key insertion hole 124, and the like. The power switch 122 is a start switch for supplying power to each unit including the main controller 130.

  The reset switch 123 is a switch for resetting various states of the slot machine 10. This slot machine 10 has a backup function for various data, and even if a power failure occurs, it retains the state at the time of the power failure and returns to the state at the time of the power failure at the time of recovery from power failure (power recovery). It can be done. Therefore, for example, when the power supply is shut down by a normal procedure, such as when the game hall is closed, the state before the power shut-off is stored, but if the power switch 122 is turned on while pressing the reset switch 123, the backup data is reset. It has become so. If the reset switch 123 is pressed while the power switch 122 is on, the error state is reset.

  The setting key insertion hole 124 is used by a hole manager or the like to adjust the appearance of medals. That is, the setting state (winning probability setting process) of the slot machine 10 can be changed from “setting 1” to “setting 6” by operating the hole manager or the like by inserting the setting key into the setting key insertion hole 124. It has become.

  As shown in FIG. 4, the main control device 130 is attached to the back plate 11 c of the housing 11 above the reel unit 41. The main control device 130 includes a CPU that controls the main control, a ROM that stores a game program, a RAM that temporarily stores necessary data according to the progress of the game, a port that communicates with various devices, time counting and synchronization. A main board including a clock circuit and the like used in the case of planning is provided, and the main board is accommodated in a board case 132 as an encapsulating means made of a transparent resin material or the like.

  Details of the configuration of the main controller 130 and how to attach it to the housing 11 will be described later.

  Next, the electrical configuration of the slot machine 10 will be described based on the block diagram of FIG.

  The main control device 130 is equipped with a microcomputer centering on a CPU 151 as arithmetic processing means. In addition to the power supply device 161 provided in the power supply box 121, the CPU 151 is connected to a clock circuit 154 that outputs a rectangular wave having a predetermined frequency, an input / output port 155, and the like via an internal bus. The main control device 130 functions as a main board built in the slot machine 10.

  On the input side of the main controller 130, a start detection sensor 71a that detects the operation of the start lever 71, stop detection sensors 72a, 73a, and 74a that individually detect the operation of the stop switches 72, 73, and 74, a medal thrower 75, an inserted medal detection sensor 75a for detecting a medal inserted from 75, credit insertion detection sensors 77a, 78a, 79a for individually detecting operations of credit insertion switches 77, 78, 79, and a switch for detecting an operation of the changeover switch 80. Detection sensor 80 a, reel index sensor 55 that individually detects the rotational position (origin position) of each reel 42, payout detection sensor 91 a that detects medals paid out from the hopper device 91, and reset detection sensor that detects the operation of the reset switch 123 123a, set to setting key insertion hole 124 Chromatography are connected various sensors such as setting the key detection sensor 124a for detecting that it has been inserted, the signals from these various sensors are outputted to the CPU151 through the input and output ports 155.

  The inserted medal detection sensor 75a is actually composed of a plurality of sensors. The main controller 130 monitors the order in which the first sensor and the second sensor are turned on / off, the first and second sensors are both off, only the first sensor is on, the first and second sensors are both on, It is determined that the medal has been normally taken in only when the sensor is turned on and both the first and second sensors are turned off and when the time for switching to each on / off switch is within a predetermined time. Otherwise, it is an error. The reason for this is to prevent fraud in which a medal is reciprocated near the inserted medal detection sensor 75a and misidentified as a medal inserted.

  Further, a power failure monitoring circuit 161 b provided in the power supply device 161 is connected to the input side of the main control device 130 via the input / output port 155. The power supply board 161 includes a power supply unit 161 a that supplies driving power to the electronic devices of the slot machine 10 including the main controller 130, the power failure monitoring circuit 161 b described above, and the like.

  The power failure monitoring circuit 161b is for monitoring the power-off state and generating a power failure signal not only at the time of power failure but also at the time of power-off by the power switch 122. For this reason, the power failure monitoring circuit 161b monitors the stabilized drive voltage of 12 VDC in this example output from the power supply unit 161a, and determines that the power supply is shut off when the drive voltage drops below, for example, 10 volts. Power outage signal is output. The power failure signal is supplied to each of the CPU 151 and the input / output port 155, and the CPU 151 recognizes this power failure signal and executes a power failure process described later.

  Even when the output voltage drops below 22 volts, the power supply unit 161a is configured to output a stabilized voltage of 5 volts used as a drive voltage in a control system such as the main controller 130. As the time during which the stabilization voltage is output, sufficient time is secured to execute the power failure process by the main controller 130.

  On the output side of the main controller 130, each of the effective line display units 32, 33, 34, the remaining number display unit 35, the game number display unit 36, the acquired number display unit 37, and the reels 42L, 42M, 42R is rotated. Stepping motors 61 (61L, 61M, 61R), a medal path switching solenoid 83 provided in the selector 84, a hopper device 91, a sub-control device 111, an external concentration terminal plate 171 capable of transmitting information to a hall management device (not shown), etc. Are connected via the input / output port 155.

  The sub-control device 111 is a control device for driving the upper lamp 13, the speaker 14, the auxiliary display unit 15, the backlight 105, and the electric motor 223a, and a CPU, ROM, RAM, and the like for driving these are integrated. Provided with a substrate. Then, after receiving a signal from the main control device 130, the sub-control device 111 independently controls driving of the upper lamp 13, the speaker 14, and the auxiliary display unit 15. Therefore, the sub-control device 111 is a sub-base that executes auxiliary control in relation to the main control device 130 that is a main base that manages and manages the game. In other words, the sub-base is provided for voice, lamp, and display related to indirect games, thereby reducing the burden on the main base. In addition, it is good also as a structure which the sub control apparatus 111 controls the various display parts 32-37.

  The CPU 151 described above stores various control programs executed by the CPU 151 and a ROM 152 storing fixed value data, and temporarily stores various data when the control program stored in the ROM 152 is executed. In addition to the RAM 153 for securing the area, although not shown, various processing circuits necessary for the slot machine 10 such as an interrupt circuit, a timer circuit, a data transmission / reception circuit, etc., as well known, and a credit counter for counting the number of credits Various counters such as are built-in. The ROM 152 and the RAM 153 constitute a main memory as storage means, and a program for executing the processes shown in the various flowcharts shown in FIGS. 10 to 19 is stored in the ROM 152 described above as a part of the control program. Yes.

  The RAM 153 has a configuration in which a backup voltage is supplied from the power supply device 161 provided in the power supply box 121 and data can be retained (backed up) even after the power of the slot machine 10 is shut off. In addition to a memory and an area for temporarily storing various data and the like, a backup area is provided.

  In the backup area, when the power is shut down due to the occurrence of a power failure or the like, the values of the stack pointer, each register, I / O, etc. when the power is shut down (including power shut down by operating the power switch 122; the same applies hereinafter) When the power failure is resolved (including power-on by operating the power switch 122. The same applies hereinafter), the slot machine 10 is in the state before power-off based on the backup area information. It is possible to return to the state. Writing to the backup area is executed when the power is shut off by the power failure process (see FIG. 12), and the restoration of each value written in the backup area is executed in the main process (see FIG. 13) when the power is turned on. Note that a power failure signal from the power failure monitoring circuit 161b is input to the NMI terminal (non-maskable interrupt terminal) of the CPU 151 when the power is interrupted due to the occurrence of a power failure or the like. NMI interrupt processing as flag generation processing is immediately executed.

  Next, each control process executed by the CPU 151 in the main controller 130 will be described with reference to the flowcharts of FIGS. The processing of the CPU 151 is broadly divided into a main processing that is started when the power is turned on, a timer interrupt processing that is started periodically (in a cycle of 1.49 msec in the present embodiment), and an NMI terminal (non-maskable terminal). For convenience of explanation, the NMI interrupt process and the timer interrupt process will be described first, and then the main process will be described.

  FIG. 10 is a flowchart illustrating an example of the NMI interrupt process. When the power is shut off due to the occurrence of a power failure or the like, the power failure monitoring circuit 161b of the power supply device 161 generates a power failure signal and outputs it to the main controller 130. In main controller 130 that has received the power failure signal via the NMI terminal, NMI interrupt processing is executed.

  In the NMI interrupt processing, first, in step S 101, the data of the used register provided in the CPU 151 is saved in the backup area provided in the RAM 153. Subsequently, in step S102, the power failure flag is set in a power failure flag storage area provided in the RAM 153. Thereafter, the data saved in the backup area of the RAM 153 in step S103 is restored to the use register of the CPU 151 again. With this return processing, the NMI interrupt processing ends. If the power failure flag can be set without destroying the data in the register used by the CPU 151, the saving and restoring processing to the backup area can be omitted.

  FIG. 11 is a flowchart of timer interrupt processing periodically executed by the main control device 130, and a timer interrupt is generated by the CPU 151 of the main control device 130 every 1.49 msec, for example.

  First, in the register saving process shown in step S201, the values of all the registers in the CPU 151 used in the normal process described later are saved in the backup area of the RAM 153. In step S202, it is confirmed whether or not a power failure flag is set. If the power failure flag is set, the process proceeds to step S203, and a power failure process is executed.

  Here, the power failure process will be described with reference to FIG. Since the power failure process is performed immediately after the register saving process in the timer interrupt process, other interrupt processes can be executed without interruption. Therefore, for example, during the transmission process of various commands and during the reading process of the switch state (ON or OFF), the interruption process is not executed and this power failure process is not executed. This eliminates the need to create a power failure processing program that takes this into consideration. This simplifies the processing program for power failure processing and reduces the program capacity. This also applies to a processing program for power recovery processing described later.

  In step S301, it is determined whether command transmission has been completed. If the transmission has not ended, the process returns to the original process of FIG. In this way, it is determined whether or not the command transmission is completed at the initial stage of the power failure process, the transmission process is prioritized when the transmission is incomplete, and the power failure process is executed after the unit command transmission process is completed. By doing so, it is no longer necessary to construct a power failure processing program that takes into account that power failure processing is executed during command transmission. As a result, the power failure processing program can be simplified and the ROM 152 can be reduced in capacity.

  If step S301 is YES, that is, if the command transmission is completed, the process proceeds to step S302, and the value of the stack pointer of the CPU 151 is stored in the backup area in the RAM 153. Thereafter, in step S303, a RAM determination value, which will be described later, is cleared as a stop process and the output state of the output port in the input / output port 155 is cleared, and all actuators (not shown) are turned off. In step S304, a RAM determination value is calculated and stored in the backup area. The RAM determination value is specifically a 2's complement of the checksum value at the work area address of the RAM 153. By storing the RAM determination value in the backup area, the checksum of the RAM 153 becomes zero. By setting the checksum of the RAM 153 to 0, subsequent RAM access is prohibited in step S305. After that, an infinite loop is entered in preparation for the case where the power supply is completely shut down and processing cannot be executed.

  The power supply unit 161a of the power supply device 161 holds the output of the stabilization voltage (5 volts) used as the drive voltage for the control system for a time sufficient to execute the above-described NMI interrupt processing and power failure processing. It is comprised so that. In the present embodiment, the drive voltage is continuously output for 30 msec.

  Returning to the description of the timer interrupt process, if the power failure flag is not set in step S202, various processes after step S204 are performed.

  That is, in step S204, a watchdog timer clearing process for initializing the value of the watchdog timer for monitoring the occurrence of malfunction is performed. In step S205, an interrupt end declaration process for giving an interrupt permission to the CPU 151 itself is performed. In step S206, in order to rotate the reels 42L, 42M, and 42R, a stepping motor control process for driving the stepping motors 61L to 61R, which are the respective rotary drive motors, is performed. In step S207, sensor monitoring processing for monitoring the state of various sensors (see FIG. 14) connected to the input / output port 155 is performed. In step S208, timer calculation processing for subtracting the value of each counter or timer is performed. In step S209, counter processing for counting the number of medals bet and the number of payouts is performed.

  In step S210, command output processing for transmitting a command or the like to the sub-control device 111 is performed. In step S211, a segment data setting process for setting segment data displayed on the remaining number display unit 35, the game number display unit 36, and the acquired number display unit 37 is performed. In step S212, segment data set processing in the segment data setting processing is supplied to the display units 35 to 37, and segment data display processing for displaying corresponding numbers, symbols, and the like is performed. In step S213, port output processing for outputting data corresponding to the I / O device from the input / output port 155 is performed. In step S214, the value of each register saved in the backup area in the previous step S201 is restored to the corresponding register in the CPU 151. Thereafter, in step S215, an interrupt permission process for permitting the next timer interrupt is performed, and this series of timer interrupt processes is terminated.

  FIG. 13 is a flowchart showing a main process in main controller 130 executed after power-on. The main process is executed when the power is turned on by recovery from a power failure or by turning on the power switch 122.

  First, in step S401, as initialization processing, the value of the stack pointer is set in the CPU 151, and an interrupt mode that permits interrupt processing is set. Thereafter, various settings for the register group in the CPU 151, the I / O device, and the like are set. And so on.

  When these initialization processes are completed, it is next determined in step S402 whether or not the reset switch 123 has been turned on. If the reset switch 123 has been turned on, the process proceeds to step S403, and all data stored in the RAM 153 is cleared as a RAM clear process.

  After confirming that the reset switch has not been operated in step S402 or performing a RAM clear process in step S403, it is determined in step S404 whether or not a setting key has been inserted into the setting key insertion hole 124. To do. If the setting key has been inserted, the process proceeds to step S405 to perform setting change processing. As the setting change process, first, all data stored in the RAM 153 is cleared. Then, after determining which setting state is selected from the six preset setting states (“Setting 1” to “Setting 6”), internal processing corresponding to the selected setting state is executed. .

  In step S406, it is confirmed whether or not a power failure flag is set. When the power failure flag is not set, that is, when the data in the RAM 153 is cleared in the previous step S403 or step S405, the process proceeds to a normal process in step S407 to be described later, and this process ends.

  When the power failure flag is set in step S406, the process proceeds to the power recovery process shown in step S408 and thereafter. The fact that the power failure flag is set means that subroutine processing such as RAM clear processing in step S403 and setting change processing in step S405 is not executed at all. Therefore, the data in the RAM 153 is not rewritten at all, and the power recovery process requires confirmation processing such as whether or not the data in the RAM 153 is normal.

  For this purpose, first, in step S408, it is confirmed whether or not the RAM determination value is normal. More specifically, the checksum of the RAM 153 is checked to check whether the value is normal, that is, whether the checksum taking into account the RAM determination value is 0. If the checksum value including the RAM determination value is 0, it is determined that the data in the RAM 153 is normal.

  If the RAM determination value is abnormal in step S408, that is, if the checksum value is not 0, there is a high possibility that the data in the RAM 153 has been destroyed. Therefore, in such a case, an error display process is performed in step S409. As error display processing, interrupt processing is first prohibited and all output ports in the input / output port 155 are cleared to control all actuators connected to the input / output port 155 to an off state. Thereafter, an error display for notifying the occurrence of an error to the hall manager or the like is performed, and this state is maintained until the reset switch 123 is turned on.

  If it is determined in step S408 that the RAM determination value is normal, the process proceeds to step S410, the stack pointer value stored in the backup area is written to the stack pointer of the CPU 151, and the stack state before the power is shut off is written. Return to the state. Next, in step S411, a power recovery command for transmitting the power recovery process is transmitted to the sub-control device 111. Thereafter, in step S412, the game state is stopped and automatic settlement setting storage processing is performed. In step S413, various sensors such as the start detection sensor 71a are initialized. After the above processing is completed, the power failure flag is reset in step S414, and the processing returns to the address before the power is shut off. Specifically, the process returns to the timer interrupt process described above, and the watchdog timer clear process (step S204) is executed.

  Next, normal processing for performing main control related to the game will be described based on the flowchart of FIG.

  First, in step S501, it is determined whether or not a medal is bet. If a medal is bet, it is subsequently determined in step S502 whether the start lever 71 has been operated. If both step S501 and step S502 are YES, the lottery process in step S503, the reel control process in step S504, the medal payout process in step S505, and the special game state process in step S506 are executed in order, and the process returns to step S501. On the other hand, if no medal is bet in step S501 or the start lever 71 is not operated in step S502, the process returns to step S501.

  Next, the lottery process in step S503 will be described based on the flowchart of FIG.

  In step S601, the random number table for determination of success / failure is selected based on the current setting state of the slot machine 10, the number of medals bet, and the small / probable combination probability. Here, the setting state of the slot machine 10 is any one of “setting 1” to “setting 6” set using a setting key (not shown), and the random number having the lowest winning probability of the combination when “setting 1” is set. A table is selected, and when “setting 6” is selected, the random number table having the highest winning probability of the combination is selected. Further, the number of medals bet is any one of 1 to 3, and a random number table is selected such that the winning probability of winning combination increases as the number of bets increases. For example, the winning probability of a winning combination when three bets are higher than the winning probability of winning when a single bet is three times. In addition, there are two types of small role probabilities: a random number table with a high small role winning probability is selected when the current payout rate is lower than the predetermined expected value, and small when the current winning rate is higher than the predetermined expected value. A random number table with a low winning probability is selected.

  In step S602, a random number table selected in this way is used for lottery in light of the random numbers latched by the random number counter when the start lever 71 is operated. In step S603, it is determined whether or not any of the winning combinations has been won. If any of the winning combinations has not been won, the process is terminated. If any of the winning combinations is won, the process proceeds to step S604, where a winning flag corresponding to the winning combination is set and an effective line to be aligned is determined. In step S605, a slip table for reel stop control is determined and stored in the slip table storage area of the RAM 153. Here, when the symbols on the predetermined effective line at the timing when the stop switches 72 to 74 are pressed are different from the symbols to be stopped on the effective line, the slip table is a predetermined symbol to be stopped. It is a table that defines how much the reel slides so as to stop on the active line.

  Next, the reel control processing in step S504 will be described based on the flowchart of FIG.

  In the reel control process, first, a wait process is performed in step S701. This wait process is a process of waiting without starting the reel rotation in the current game until a predetermined time (for example, 4.1 seconds) elapses from the time when the reel rotation is started in the previous game. Therefore, even if the player bets a medal and operates the start lever 71, the reels 42L, 42M, and 42R may not immediately rotate. Following the weight process, the reel rotation process of step S702 is performed to rotate the reels 42L, 42M, and 42R. Thereafter, the process proceeds to step S703, and it is determined whether or not any of the stop switches 72 to 74 is pressed to generate a reel stop command. If no stop command has been issued, the process advances to step S704 to determine whether or not a predetermined maximum rotation time (for example, 40 seconds) of each reel 42L, 42M, 42R has elapsed. If the maximum rotation time has not elapsed, the process returns to step S703. If the maximum rotation time has elapsed, the process proceeds to step S705 to perform a forced stop process for forcibly stopping all the rotating reels.

  On the other hand, if any one of the stop switches 72 to 74 is pressed in step S703 and a stop command is generated, the process proceeds to step S706 to perform reel stop processing. In this reel stop process, the reel corresponding to the pressed stop switch is stopped. If a winning combination is won in the winning lottery and the winning flag is set, the reel is stored in the sliding table storage area of the RAM 153. With reference to the sliding table, control is performed so that the winning combinations are arranged on a predetermined effective line as much as possible. For example, when the “watermelon” symbol is lined up on the lower line and the stop switch is pressed at the timing when the “watermelon” symbol stops on the upper line, the symbol 2 is set so that it stops on the lower line. Slide the reel as much as you can. However, since the range that can be slid is determined in advance (for example, up to four symbols), the “watermelon” symbol may not stop on the lower line depending on the timing of pressing the stop switch. Even in the forced stop process in step S705, if the winning flag is set, the same process is performed.

  Subsequently, in step S707, it is determined whether or not the current stop command is the first stop command, that is, whether or not the stop switch has been pressed when all three reels are rotating. In the case of the first stop command, the process proceeds to step S708, and the slip table changing process is performed. In this slide table change process, for example, it is determined whether or not a combination of combinations occurs when trying to align a combination on the selected active line, and when a combination of combinations does not occur, the process proceeds to the next step as it is. When a combination of combinations occurs, the selected effective line is changed to another effective line, and after changing to a sliding table suitable for the changed effective line, the process proceeds to the next step. Here, “combination of a combination” means that, for example, when a “watermelon” symbol is arranged on the upper line, a “cherry” symbol appears on the lower line when the “cherry” symbol appears on the lower line. Refers to cases. The slip table changing process may be performed other than when avoiding the combination of the combinations.

  On the other hand, if the current stop command is not the first stop command in step S707, the process proceeds to step S709 to determine whether the second stop command is present, that is, one of the three reels is stopped and the two reels are rotating. It is determined whether or not the stop switch has been pressed. If it is the second stop command, the process proceeds to step S710 and a stop eye determination process is performed. In this stop eye determination process, when two reels are stopped, it is determined whether or not the two are aligned with a bonus symbol such as “7” symbol. If they are not aligned, the process proceeds to the next step as it is. When sound effects are generated from the speaker 14, the process proceeds to the next step. In the stop eye determination process, it may be determined whether another condition other than two bonus symbols is satisfied, or an effect using the auxiliary display unit 15 may be performed in addition to the sound effect.

  Then, after the forced stop process in step S705, after the slip table change process in step S708, when the current stop command is not the second stop command in step S709, or the stop eye determination process in step S710 is performed. After that, in step S711, it is determined whether or not all rotations of the left, middle, and right reels 42L, 42M, and 42R have stopped. If step S711 is NO, the process returns to step S703. If YES, the payout determination process is performed in the subsequent step S712, and then the process ends. In the payout determination process, it is determined whether or not the winning combination is arranged on the effective line. When the winning combination is not aligned on the effective line, 0 is set in the payout number storage area of the RAM 153, and the winning combination is aligned on the effective line. When it is, it is determined whether or not the winning combination matches the winning combination, and if not, an error is displayed by the upper lamp 13 or the like and 0 is set in the scheduled payout number storage area. If they match, the number of payouts corresponding to the combinations arranged in the payout amount storage area is set.

  Next, the medal payout process in step S505 will be described based on the flowchart of FIG.

  In the medal payout process, first, it is determined whether or not the payout number counted by the payout number counter in step S801 matches the planned payout number stored in the payout planned number storage area. If the number of payouts does not match the planned payout number, it is determined in step S802 whether or not the game is being performed in the credit mode. If it is in the credit mode, it is determined in step S803 whether or not the count value of the credit counter has reached the upper limit (the number of stored medals is 50). If the upper limit is not reached, the count value of the credit counter and the number of payouts are each incremented by 1 in step S804. Accordingly, the remaining number display unit 35 and the acquired number display unit 37 are each incremented by one.

  On the other hand, when the game is performed in the direct mode, or when the count value of the credit counter reaches the upper limit, the medal payout rotary plate is driven in step S805 and the medal is discharged from the hopper device 91 to the medal discharge port. 17 through the medal tray 18. At this time, in step S806, the number of payouts is incremented by 1 according to the medal detection signal of the payout detection sensor 91a attached to the hopper device 91. As a result, the number of acquired number display section 37 is incremented by one. Then, after the payout number is incremented by 1 in step S804 or step S806, the process returns to step S801 again. When the number of payouts and the planned number of payouts match in step S801, the medal payout rotating plate of the hopper device 91 is stopped in step S807, and this process is terminated. The payout number / acquired number display section 37 is reset when the start lever 71 is operated next time.

  Next, the special game state process of step S506 will be described based on the flowchart of FIG.

  Prior to the description of the special game state process, the bonus game will be described. The regular bonus (hereinafter referred to as “RB”) game is composed of 12 JAC games. The JAC game is a game in which only one bet is allowed, and is a game with a very high probability that the JAC symbols (replay symbols in this case) are aligned on the active line, that is, the probability of establishment of the JAC symbols. When a JAC symbol is established in a JAC game, the maximum number (15 in this case) of medals is paid out. When the JAC symbol is established 8 times, the RB game is ended even before the JAC game reaches 12 times. On the other hand, the big bonus (hereinafter referred to as “BB”) game is composed of 30 small role games and 3 JAC ins. A small role game is a game in which a small role is won with a high probability (“Bell” symbols etc. are on the active line), and JAC in means entering the JAC game 12 times. When JAC symbols are aligned on the active line, JAC in is established. The JAC game is the same as that of the RB game. Also, when the JAC game by the third JAC in is finished, the BB game is finished even before the small role game reaches 30 times, and before the JAC in reaches 3 times after the 30 small role games are finished. Even if there is, the BB game ends.

  In the special game state process, first, in step S901, it is determined whether or not the game state is a bonus game. If it is not during the bonus game, the process proceeds to step S902, and bonus symbol determination processing is performed.

  In this bonus symbol determination process, as shown in FIG. 19, it is first determined in step S1001 whether or not the RB winning flag is set. If it is set, the process proceeds to step S1002, and the RB symbol is placed on the current effective line. It is determined whether or not (for example, “BAR” symbols) are aligned, and if the RB symbols are not aligned, this processing is terminated. On the other hand, when the RB symbols are aligned on the active line this time, in step S1003, the RB winning flag is reset and the RB setting flag is set to make an RB game which is one type of bonus game, and the RB game initial setting process shown in FIG. To finish this processing. If the RB winning flag is not set in step S1001, it is determined whether or not the BB winning flag is set in step S1004. If it is not set, the process is terminated. When the BB winning flag is set, the process proceeds to step S1005, where it is determined whether or not the BB symbol (for example, symbol “7”) is aligned on the current effective line, and when the BB symbol is not aligned, this processing is terminated. . On the other hand, when the BB symbols are aligned on the active line this time, in step S1006, the BB winning flag is reset and the BB setting flag is set to obtain a BB game which is one type of bonus game, and the BB game shown in FIG. The initial setting process is executed and this process is terminated.

  20 and 21, the remaining small role game counter represents the remaining number of small role games (also referred to as the remaining small role game number), and the remaining JAC in counter represents the remaining number of remaining JAC in (remaining JAC in number). The remaining JAC establishment counter represents the remaining number of times that the JAC symbol can be established (also referred to as the number of remaining JAC formations), and the remaining JAC game counter represents the number of remaining JAC games (also referred to as the number of remaining JAC games). Represent. The number of remaining small role games, the number of remaining JAC ins, the number of remaining JACs established, and the number of remaining JAC games are displayed on the game number display unit 36 as appropriate. By the way, if a small role winning flag or replay winning flag is set by winning a small role or replay in the role lottery, those winning flags will not be aligned on the active line in the game. Will be reset, but if the RB winning flag or the BB winning flag is set by winning the RB or BB in the winning lottery, even if the RB symbol or BB symbol cannot be aligned on the active line in the game The winning flag will be carried over to the next time. In the lottery process in the next game that carries over the BB or RB winning flag, a lottery regarding whether or not a small role or replay is won is performed, but a lottery regarding BB or RB is not performed. In addition, when a small combination or replay is won in a state where the BB or RB winning flag is carried over, a slide table is stored so that the small combination or replay is preferentially aligned.

  Returning to FIG. 16, when the gaming state is a bonus game in step S901, it is determined in step S903 whether the bonus game is a JAC game. If it is not a JAC game, it means that the BB game is in the small role game, so the process proceeds to step S904, and it is determined whether or not the JAC symbols are aligned on the active line. When the JAC symbols are aligned on the active line, the JAC game is started in step S905 and the JAC game initial setting process during the BB game shown in FIG. 21B is performed, and this process ends. On the other hand, when the JAC symbols are not aligned on the active line in step S904, the small role game has been consumed, so in step S906 the remaining small role game number is decremented by 1, and in step S907. It is determined whether or not the number of remaining small role games has become zero. When the remaining small role game number is not 0, the present process is terminated. When the remaining small role game number is 0, the process proceeds to step S908, and a special game state end process for appropriately resetting various setting flags, BB setting flags, various counters, etc. To end this process.

  When the gaming state is a JAC game in step S903, the process proceeds to step S909 to determine whether or not the JAC symbols are aligned on the active line. When the JAC symbols are aligned on the active line, the number of remaining JACs established is determined in step S910. Decrement by one. After that, or when the JAC symbols are not aligned on the active line in step S909, one JAC game has been consumed, so the number of remaining JAC games is decremented by 1 in step S911. Subsequently, in step S912, it is determined whether or not any of the remaining number of JACs or the number of remaining JAC games has become 0. If neither is 0, that is, the JAC symbol has not yet been established 8 times. If the JAC game has not been digested 12 times, the process is terminated as it is. On the other hand, if any of them is 0, that is, if the JAC symbol is established 8 times or the JAC game is digested 12 times, the JAC in is digested once, so in step S913 the remaining JAC in The number of times is decremented by 1, and in the subsequent step S914, it is determined whether or not the number of remaining JAC in is zero. When it is 0, the special gaming state termination process of step S908 described above is performed, and this process is terminated. Incidentally, if the bonus game is an RB bonus, the initial remaining JAC in number is 1 (see FIG. 20), so it becomes 0 in step S913, and a positive determination is always made in step S914, and the special game in step S908. The RB setting flag is reset in the state end process.

  On the other hand, when the number of remaining JAC ins is not zero in step S914, that is, when the JAC in has not been digested three times in the BB game, after performing the JAC game end processing for resetting the JAC game setting flag in step S915, When the player enters the game, one of the small role games is digested, so the number of remaining small role games is decremented by 1 in step S906, and then whether or not the remaining small role game number has become 0 in step S907. If it is determined that the number of remaining small role games is 0, the special game state ending process in step S908 described above is performed, and this process is ended. On the other hand, when the remaining small-combination game number is not 0, the small-combination game in the BB bonus has not reached 30 times and the JAC in has not reached 3 times.

  FIG. 22 is an exploded perspective view of the main controller 130 according to the first embodiment of the present invention.

  As shown in the figure, the main controller 130 includes a main board 131, a board case 132, a base 135, a mounting portion 136, an engaged member 137, and a coupling pin 138.

  The main board 131 includes a CPU 151, a ROM 152, a RAM 153, a clock circuit 154, a port 155, and the like (see FIG. 9), and controls processing when playing a game in the slot machine 10. The main board 131 is accommodated in a board case 132 including a board case 132.

  In the main board 131, a through hole 131a is formed at a position corresponding to a screw hole 133d of the first case 133 described later so that a screw 139a can be inserted.

  The substrate case 132 includes a substrate case 132.

  As shown in FIGS. 22 and 23 (a front view of the first case 133), the first case 133 includes an accommodation portion 133a and a connecting portion 133e. Is arranged on the front door 12 side of the slot machine 10.

  The accommodating portion 133a includes a flat front surface 133b that is erected on the front door 12 side, and a peripheral surface 133c that stands upright from a peripheral edge of the front surface 133b toward a second case 134 described later. The main board 131 can be accommodated in a space surrounded by the peripheral surface 133c.

  Here, as shown in FIG. 23, two screw holes 133d for fixing the main board 131 are formed at diagonal positions of the housing portion 133a in the housing portion 133a in the present embodiment. The main board 131 is fixed to the first case 133 via screws 139a. Since the screws 139a are fixed in this way, the main board 131 can be detached by removing the screws 139a.

  In the present embodiment, the front surface 133b is formed in a rectangular shape and the accommodating portion 133a is formed in a rectangular parallelepiped shape as a whole. However, the main substrate 131 can be accommodated with respect to the size and shape of the accommodating portion 133a. The range can be changed as appropriate.

  The connection part 133e is formed above the accommodating part 133a. The connecting portion 133e mainly serves to connect the first case 133 to the second case 134.

  For example, in the present embodiment, the connecting portion 133e has a first screwing portion 133f having a screw hole that opens in the direction of the second case 134 and a through hole that opens in the direction of the second case 134. A second screwing portion 133g having a first pinning portion 133h and a second pinning portion 133i having a through-hole opening in the direction of the second case 134 are provided. In addition, the connection method with the 2nd case 134 using these is mentioned later.

  Further, the connecting portion 133e is provided with an opening 133j penetrating in the direction of the second case 134 between the housing portion 133a, and, as will be described later, from the opening 133j, the second case 134 is provided. The connecting pin 138 can be inserted into the connecting portion 134j.

  Furthermore, in this embodiment, as shown in FIG. 23, hook through holes 133k are provided in the side portions of the accommodating portion 133a and the connecting portion 133e, and are formed in the second case 134 described later. The first case 133 and the second case 134 are moved relative to each other by inserting the hook 134p into the hook through-hole 133k and moving the first case 133 downward or the second case 134 upward. The second case 134 can be fitted together.

  Note that the first case 133 is formed of a transparent resin having translucency that allows the main substrate 131 attached inside to be observed from the outside.

  As shown in FIGS. 22 and 24 (a front view of the second case 134), the second case 134 includes an accommodating portion 134a and a connecting portion 134e. It arrange | positions at the board 11c side.

  The accommodating portion 134a includes a planar back surface 134b that is erected on the back plate 11c side, and a peripheral surface 134c that stands upright from the periphery of the back surface 134b toward the first case 133. The back surface 134b and the peripheral surface The main board 131 can be accommodated in a space surrounded by 134c.

  In the present embodiment, the back surface 134b is formed in a rectangular shape and the housing portion 134a is formed in a rectangular parallelepiped shape as a whole. However, the size and shape of the housing portion 134a can accommodate the main board 131. It can be appropriately changed within the range where it can be made.

  Here, the hook 134p is formed in the front-end | tip of the surrounding surface 134c located in the side of the accommodating part 134a.

  As shown in FIG. 22, the hook 134p includes a space part 134q extending toward the first case 133 and a hook body 134r extending upward from the tip of the space part 134q. Then, the hook 134p is inserted into the hook through hole 133k formed in the first case 133, and the first case 133 is moved downward or the second case 134 is moved relatively upward. Thus, the first case 133 and the second case 134 can be fitted together.

  The space portion 134q is configured so that the hook body 134r is spaced from the second case 134 by a predetermined distance so that the hook body 134r is fitted into the hook through-hole 133k formed in the first case 133. So that you can

  The connection part 134e is formed above the accommodating part 134a. The connecting portion 134 e plays a role of connecting the second case 134 to the first case 133 and a role of attaching the second case 134 to the base 135 via the engaged member 137.

  For example, as shown in FIG. 24, the connecting portion 134e has a third screwing portion 134f having a through hole that opens in the direction of the first case 133, and an opening in the direction of the first case 133. A fourth screwing portion 134g having a threaded hole, and a third pinning portion 134h and a fourth pinning portion 134i having a through hole opening in the direction of the first case 133 are provided. .

  And the position where the screw hole of the 1st screwing part 133f formed in the 1st case 133 and the through-hole of the 3rd screwing part 134f formed in the 2nd case 134 oppose In such a state, the screws 139b are screwed into the through holes and the screw holes from the second case 134 side, so that they are fixedly connected. Further, a position where the through hole of the second screwing portion 133g formed in the first case 133 and the screw hole of the fourth screwing portion 134g formed in the second case 134 face each other. In such a state, the screw 139b is screwed into the through hole and the screw hole from the first case 133 side, so that they are fixedly connected. Furthermore, the through hole of the first pinning portion 133h formed in the first case 133 and the through hole of the third pinning portion 134h formed in the second case 134 are opposed to each other, Further, the through hole of the second pinning portion 133i formed in the first case 133 and the through hole of the fourth pinning portion 134i formed in the second case 134 are opposed to each other. In this state, a pin 139c is fitted into at least one of these through holes from the first case 133 side, so that they are fixedly connected.

  By fitting the pin 139c in this way, the pin 139c is not damaged unless the first pinned portion 133h and the third pinned portion 134h, or the second pinned portion 133i and the fourth pinned portion 134i are destroyed. Since the board case 132 is not easily opened, and the board case 132 is opened, the first pinning part 133h or the third pinning part 134h, or Since the trace which destroyed the 2nd pinning part 133i or the 4th pinning part 134i remains, it can confirm that there was unauthorized opening.

  The pin 139c can be fitted into a through hole formed in the first pinning portion 133h, the second pinning portion 133i, the third pinning portion 134h, and the fourth pinning portion 134i. What is necessary is just to select the shape and magnitude | size suitably in the possible range.

  As described above, since the main board 131 is accommodated in the board case 132, the main board 131 cannot be touched unless the main board 131 is taken out from these cases. Further, since the first case 133 and the second case 134 are connected by two screws 139b and one pin 139c, the connection cannot be easily released.

  Further, as shown in FIG. 24, the coupling portion 134e is formed with four coupling portions 134j.

  The coupling portion 134j includes a coupling portion main body 134l having a through hole 134k that opens in a direction perpendicular to the back surface 134b, and a bridge portion 134m that couples the coupling portion main body 134l to the coupling portion 134e. Accordingly, the coupling portion main body 134l can be detached from the connecting portion 134e by cutting the bridge portion 134m.

  In addition, in this embodiment, although four coupling | bond part main bodies 134l are formed, about this number, it can change suitably. Moreover, although the number of the bridge parts 134m in one coupling | bond part main body 134l is also made into four, it can change suitably also about this number.

  The coupling portion 134j is used when the coupling pin 138 is hooked on the engaged member 137, and a specific usage method will be described later.

  Further, it is desirable to form the connecting portion 134e above the substrate case 132.

  For example, as shown in FIG. 4, since the main controller 130 is often located above the device to be connected, it is desirable to concentrate the wiring to other devices downward. If the portion 124e is formed below, the connecting portion 124e is hidden by the wiring, which is inconvenient for checking the state of the connecting portion 134e or the coupling pin 138 and for opening the substrate case 132.

  It is desirable that the shaft member 139d that pivotably connects the base 135 and the mounting portion 136 is also provided below so that the wiring is not moved much by concentrating the wiring below the main controller 130. Therefore, when the base 135 and the substrate case 132 are rotated to the front of the housing 11 in order to confirm the back surfaces thereof, there is some room for access to some extent above and on the back side of the main controller 130. There is an actual advantage of preventing fraud according to the present invention against fraud in which the coupling pin 138 is removed from the back side of the main controller 130, the board case 132 is opened, and an unauthorized main board 131 is attached.

  Note that the second case 134 is also formed of a transparent resin having translucency to such an extent that the main substrate 131 accommodated therein can be observed from the outside, similarly to the first case 133. .

  As shown in FIG. 22, the base 135 has a planar rear surface 135a standing on the back plate 11c side, a bottom surface 135b standing upright from the lower portion of the rear surface 135a, and a front side from the side of the rear surface 135a. An upright side surface 135c.

  The side surface 135c is provided with a latching portion 135d extending in the direction of the side surface 135c facing each other at the tip of the side surface 135c.

  The interval between the latching portion 135d and the rear surface 135a is formed substantially the same as the thickness of the substrate case 132. Therefore, the substrate case 132 can be attached to the base 135 by inserting the substrate case 132 from above the base 135 between the latching portion 135d and the rear surface 135a and sliding it toward the bottom surface 135b. Has been.

  Four fitting portions 135e are formed on the rear surface 135a at positions facing the coupling portion main body 134l formed on the second case 134 when the substrate case 132 is slid and attached to the base 135. Yes.

  As shown in FIG. 25 (a cross-sectional view of one fitting portion 135e taken along line 25-25 in FIG. 22), the fitting portion 135e is formed between the surface of the rear surface 135a and the cover portion 135g. The concave portion 135f and two through holes 135h that are formed inside the concave portion 135f and fix an engaged member 137 to be described later.

  Here, regarding the size and shape of the recessed portion 135f, an engaged member main body 137a of an engaged member 137 described later is accommodated in the recessed portion 135f, and the engaged member main body 137a protrudes from the surface of the rear surface 135a. Form so as not to.

  In this way, by forming the engaged member main body 137a so as not to protrude from the surface of the rear surface 135a, when the substrate case 132 is slid and attached to the base 135, the substrate case is attached to the engaged member main body 137a. 132 is not caught.

  The cover part 135g is formed in a size and shape so that the coupling pin 138 does not interfere with the fitting part 135e when a coupling pin 138 described later is hooked on the engaged member 137.

  Furthermore, the maximum width A of the two through holes 135h is the same as or slightly smaller than the maximum width B of two columnar portions 137c formed in the engaged member 137 described later. For this reason, the columnar portion 137c is elastically deformed so that the claw portion 137d formed at the tip of the columnar portion 137c penetrates the through-hole 135h. Otherwise, the engaged member 137 is prevented from being detached from the inside of the recess 135f.

  On the other hand, for example, when the claw portion 137d is formed so as to protrude in a direction in which the two columnar portions 137c oppose each other, the minimum width of the two through holes 135h is an engaged member described later. The engagement member 137 is fixedly attached by the elastic force of the columnar portion 137c by forming it so as to be the same as or slightly smaller than the minimum width of the two columnar portions 137c formed on the 137.

  Note that the size and shape of the through-hole 135h are appropriately selected and formed so that a claw portion 137d described later can be penetrated.

  Here, since neither the recess 135f nor the through-hole 135h has a protrusion in the vertical direction with respect to the rear surface 135a, the base 135 can be easily formed by a mold formed so as to sandwich the rear surface 135a.

  In addition, a through hole 135i having an axis in the horizontal direction is formed at the tip of the bottom surface 135b, and the axis of the through hole 135i is formed in a through hole 136d formed in a bottom plate 136b of the mounting portion 136 described later. By inserting the shaft member 139d into these through holes in a state of being continuous with the axis, the base 135 is rotatably connected to the mounting portion 136 via the shaft member 139d.

  The mounting portion 136 includes a flat plate surface 136a standing on the back plate 11c side, a bottom plate 136b standing upright from the lower end of the plate surface 136a, and a holding portion 136c for holding the base 135 in an upright state. It is equipped with.

  A through hole 136d having an axis in the horizontal direction is formed at the tip of the bottom plate 136b. The shaft member 139d is inserted into these through-holes in a state where the axes of the through-hole 136d and the through-hole 135i formed at the tip of the bottom surface 135b of the base 135 are continuous. The base 135 is rotatably connected to the mounting portion 136.

  The holding portion 136c includes a spacer portion 136e that extends forward from the side of the plate surface 136a, and a claw portion 136f that is formed at the tip of the spacer portion 136e.

  The width between the opposing spacer portions 136e is the same as the width between the side surfaces 135c of the base 135, and the depth of the spacer portion 136e is formed in the same manner as the depth (thickness) of the base 135. The claw portion 136f is formed so as to protrude in the direction of the holding portion 136c facing each other.

  Here, the spacer part 136e is configured such that the claw part 136f is caught on the surface of the base 135 by providing a predetermined gap between the claw part 136f and the plate surface 136a.

  By forming the holding portion 136c in this way, the base 135 is rotated with respect to the mounting portion 136, and this holding is performed when the rear surface 135a of the base 135 faces the plate surface 136a of the mounting portion 136. The portion 136c is elastically deformed to the side so that the side surface 135c of the base 135 is positioned on the inner side (the plate surface 136a side) of the claw portion 136f, and the elastic deformation of the holding portion 136c is returned, so that the claw portion 136f is The base 135 can be held in an upright state by being caught at the tip of the side surface 135c of the 135.

  Further, the attachment portion 136 is provided with a screw through hole 136g, and the screw is fixed to the back plate 11c by screwing the screw into the back plate 11c of the housing 11 through the screw through hole 136g. The

  The base 135 is also formed of a transparent resin having translucency that allows the back of the substrate case 132 to be observed from the outside, so that the substrate case 132 or the main substrate 131 accommodated therein can be stored. You can check the back.

  As shown in FIGS. 22 and 26 (a top view of the engaged member 137), the engaged member 137 includes an engaged member main body 137a, two insertion portions 137b, and a tubular portion 137h. , Through hole 137f.

  The engaged member main body 137a is formed in a flat plate shape and has a size and a shape that can be fitted into the recess 135f formed in the fitting portion 135e of the base 135.

  Here, in the present embodiment, the engaged member main body 137a is formed in a plate shape having sides larger than the diameter of the through hole 134k formed in the coupling portion 134j, and passes through the through hole 134k. It is formed so that it cannot be. In addition, about the magnitude | size and shape of the to-be-engaged member main body 137a, it is caught in the coupling part 134j and the to-be-engaged member 137 cannot be removed toward the 1st case 133 from the connection part 134e of the 2nd case 134. What should I do?

  Two insertion portions 137b extending in the same direction are formed on one surface of the engaged member main body 137a.

  Each insertion portion 137b is provided with a columnar portion 137c connected to the engaged member main body 137a and a claw portion 137d.

  As described above, the maximum width B of the two columnar portions 137c is the same as or slightly larger than the maximum width A of the two through holes 135h formed at the bottom of the recess 135f of the base 135. Yes.

  As for the length of the columnar portion 137c, the claw portion 137d formed at the tip of the columnar portion 137c when fitted into the concave portion 135f of the base 135 is outside the through hole 135h formed in the concave portion 135f. Form to reach up to.

  The claw portion 137d formed at the tip of the columnar portion 137c is formed so as to protrude toward the outside of the opposite columnar portion 137c, and is a surface of the claw portion 137d, and has a step between the columnar portion 137c. The step surface 137e for forming the step 137e is formed so as to be substantially perpendicular to the columnar portion 137c, so that the step surface 137e can be hooked on the outer surface of the recess 135f.

  Further, a cylindrical portion 137h extending in the same direction as the extending direction of the insertion portion 137b is formed at the center of the engaged member main body 137a.

  The cylindrical portion 137h is configured such that an engagement claw 138c of a coupling pin 138, which will be described later, can be hooked on the tip edge 137g. In addition, you may enable it to be able to hook the engaging claw 138c on the to-be-engaged member main body 137a, without providing such a cylindrical part 137h.

  The engaged member main body 137a and the tubular portion 137h are formed with through holes 137f that open in the extending direction of the columnar portion 137c.

  The through hole 137f is for inserting a coupling pin 138, which will be described later, and has a size and shape that can be inserted by bending the claw portion 137d formed in the coupling pin 138 inward. What is necessary is just to form.

  In the present embodiment, the shape of the through hole 137f is formed in a columnar shape corresponding to the shape of the coupling pin 138. By forming the columnar shape in this way, the coupling pin 138 can be inserted into the through hole 137f without being aligned in the circumferential direction.

  As illustrated in FIG. 27 (a top view of the coupling pin 138), the coupling pin 138 includes a flange portion 138a and an insertion portion 138b, and is formed in a cylindrical shape as a whole.

  The flange portion 138a has a larger diameter than the through hole 134k formed in the coupling portion main body 134l of the second case 134, and is formed in a size and shape that cannot pass through the through hole 134k. Yes.

  An insertion portion 138b is formed to extend in one direction from the flange portion 138a.

  The insertion portion 138b includes a columnar portion 138d and an engaging claw 138c formed at the tip of the columnar portion 138d.

  A slit 138e is inserted into the insertion portion 138b from the distal end to a predetermined position. Therefore, the distal end of the insertion portion 138b can be bent inward with the slit 138e interposed therebetween. The width and depth of the slit 138e can be selected as appropriate according to how much the slit 138e is bent.

  The columnar portion 138d is formed in a columnar shape as a whole, and its outer diameter is equal to the inner diameter of the through hole 137f so that it can be inserted into the through hole 137f formed in the engaged member 137. It is formed so as to be substantially the same or slightly smaller.

  An engaging claw 138c is formed at the tip of the columnar portion 138d.

  The engaging claw 138c is formed so as to protrude outward from the outer periphery of the columnar portion 138d, and is formed so as to gradually spread outward from the tip thereof.

  The step surface 138f that is the surface of the engaging claw 138c and is opposite to the tip of the insertion portion 138b and that is the boundary with the columnar portion 138d is perpendicular to the columnar portion 138d at the maximum. By forming the stepped surface 138f, the stepped surface 138f can be hooked on the leading edge 137g of the tubular portion 137h of the engaged member 137.

  Thus, by setting the step surface 138f to be an acute angle or perpendicular to the columnar portion 138d, the step surface 138f will not be caught even if the connecting pin 138 is pulled out in the direction of the flange portion 138a.

  28 shows the relationship between the coupling portion main body 134l of the second case 134 configured as described above, the fitting portion 135e of the base 135, the engaged member 137, and the coupling pin 138 (the coupling portion main body of the second case 134). 134l, a cross-sectional view in a state where the fitting portion 135e of the base 135, the engaged member 137, and the coupling pin 138 are coupled to each other.

  As shown in FIG. 28, with the engaged member 137 fitted in the recess 135f formed in the fitting portion 135e of the base 135, the through hole 134k of the coupling portion main body 134l of the second case 134 and the covered portion The substrate case 132 is attached to the base 135 so that the through-hole 137f of the engaging member 137 communicates, and the coupling pin 138 is inserted into the through-holes 134k and 137f.

  In this manner, by attaching the substrate case 132 containing the main substrate 131 to the base 135, the engaged member 137 is caught in the recess 135f of the base 135, and the coupling pin 138 is engaged with the engaged member 137. Since the board case 132 cannot be slid above the base 135 because it is attached, and because the engaged member 137 and the coupling pin 138 are connected to the base 135, the engaged member 137 Even if the base member 137 is removed, the engaged member 137 is hooked on the coupling portion main body 134l, and the bridge portion 134m connecting the coupling portion main body 134l is cut, so that the coupling portion main body 134l, the coupling pin 138 The substrate case 132 cannot be removed from the base 135 unless the engaging member 137 is removed.

  Further, since the flange portion 138 a contacts the coupling portion main body 134 l on the opposite side of the base 135, the substrate case 132 cannot be moved to the opposite side of the base 135, and a gap is formed between the base 135 and the substrate case 132. Can be prevented from occurring.

  As described above, in the present embodiment, the substrate case 132 that accommodates the main substrate 131 is connected by sliding downward from above the base 135, and from the opposite side of the base 135 to the sliding direction. Inserts the coupling pin 138 in the intersecting direction, and hooks the engagement claw 138c of the coupling pin 138 on the engaged member 137 fitted in the recess 135f of the base 135, thereby connecting the substrate case 132 and the base 135 to each other. It is fixed. The engaging claw 138c is covered with the cover portion 135g of the base 135, and the engaging claw 138c cannot be accessed from the back surface of the base 135, and the engaged member 137 is caught by the coupling portion 134j. Therefore, the connecting pin 138 cannot be extracted from the connecting portion 134j. Therefore, in this embodiment, unless the coupling part 134j is damaged and the coupling pin 134j and the engaged member 137 are removed, the board case 132 cannot be removed from the base 135, and the security is improved.

  In the present embodiment, since the base 135 is pivotally connected to the attachment portion 136 at the lower end thereof, the base 135 can be attached to the attachment portion 136 without removing the substrate case 132 from the base 135. By rotating in a direction away from the back surface, the back surface of the substrate 131 accommodated in the substrate case 132, the back surface of the second case 134, and the back surface of the base 135 can be confirmed. By confirming these back surfaces, it is possible to confirm whether or not holes or the like are formed in these back surfaces or whether an illegal substrate is attached.

  In the embodiment described above, the bridge portion 134m of the coupling portion 134j is cut, and the claw portion 137d of the engaged member 137 is bent inward from the back surface of the base 135 to disengage the claw portion 137d. Thus, by removing the insertion portion 137b from the through-hole 135h formed in the recess 135f, the coupling pin 138, the engaged member 137, and the coupling portion main body 134l can be removed from the opening 133j of the first case 133. The substrate case 132 can be removed by sliding it above the base 135 by removing these.

  Furthermore, the coupling pin 138 extracted from the opening 133j of the first case 133 and the engaged member 137 can be removed by bending the engagement claw 138c of the coupling pin 138 inward, Since the pin 138 can be removed from the coupling portion main body 134l by bending the engagement claw 138c inward, the engaged member 137 and the coupling pin 138 can be taken out and used again. Become.

  Here, with respect to the through hole 134k formed in the coupling portion main body 134l, the cross section in the vertical plane with respect to the insertion direction of the coupling pin 138 is not circular so that the engagement claw 138c can be easily removed. As described above, it is possible to form a portion whose distance from the center is longer than other portions. In this way, the coupling claw 138c can be easily positioned by aligning the coupling claw 138c with a portion having a long distance from the center.

  In the embodiment described above, the claw portion 137d of the engaged member 137 is caught by the base 135, and the engagement claw 138c of the coupling pin 138 is caught by the engaged member 137, so that the flange portion of the coupling pin 138 is obtained. Since 138a contacts the coupling portion 138c of the substrate case 132, the substrate case 132 cannot be moved to the front surface of the base 135, and a gap is not generated between the base 135 and the substrate case 132. For this reason, fraud using the gap between the base 135 and the substrate case 132, for example, the coupling pin 138 is cut from the gap and the coupling pin 138 is wetted, or a bar or the like is inserted from the gap to be opened. It is possible to prevent fraud such as.

  In the embodiment described above, two through holes 135h are formed in the fitting portion 135e formed in the base 135 (see FIG. 25), and the engaged member 137 is formed in the through hole 135h. The inserted member 137b is inserted and the claw portion 137d of the insertion portion 137b is hooked on the base 135 to prevent the engaged member 137 from coming off the base 135. However, the present invention is limited to this mode. It is not done.

  For example, as shown in FIG. 29 (a cross-sectional view of the fitting portion 235e), the fitting portion 235e can be configured by a concave portion 235f and a cover portion 235g surrounding the concave portion 235f. . In such a case, as shown in FIG. 30 (a top view of the engaged member 237), the engaged member 237 includes an engaged member main body 237a, a cylindrical portion 237h, and a through hole. And 237f.

  Furthermore, in the embodiment described above, the recessed portion 135f of the fitting portion 135e and the engaged member main body 137a of the engaged member 137 are each formed in a rectangular shape, but the present invention is limited to such a mode. However, it can be formed into a shape such as a circle, an ellipse, or a polygon such as a triangle.

  The through hole 137f is for inserting a coupling pin 138, which will be described later, and has a size and shape that can be inserted by bending the claw portion 137d formed in the coupling pin 138 inward. What is necessary is just to form.

  In the present embodiment, the shape of the through hole 137f is formed in a columnar shape corresponding to the shape of the coupling pin 138. By forming the columnar shape in this way, the coupling pin 138 can be inserted into the through hole 137f without being aligned in the circumferential direction.

  Next, a second embodiment of the present invention will be described with reference to FIGS.

  The main controller 130 according to the second embodiment of the present invention is different from the first embodiment in the engaged member 337 and the coupling pin 338, and therefore, matters related to the different points. Will be described.

  In the present embodiment, it is an essential requirement that the bottom surface of the concave portion 135f formed in the base 135 is covered with the cover portion 135g and that the engaged member 337 is used. is not.

  FIG. 31 is a perspective view of the engaged member 337 used in the present embodiment.

  As shown in FIGS. 31 and 32 (side view of the engaged member 337), the engaged member 337 includes an engaged member main body 337a, two insertion portions 337b, a through hole 337g, Engaging edge 337i.

  The engaged member main body 337a is formed in a flat plate shape as in the first embodiment, and has a size and shape that can be fitted into the recess 135f formed in the fitting portion 135e of the base 135. Is formed. Further, the size and shape of the engaged member main body 337 a are formed so as to be hooked on the coupling portion main body 134 l of the second case 134.

  Two insertion portions 337b extending in the same direction are provided on one surface of the engaged member main body 337a.

  A columnar portion 337c and a claw portion 337d are formed in the insertion portion 337b.

  The columnar portion 337c extends from the engaged member main body 337a, and a claw portion 337d is formed at the tip thereof.

  As shown in FIG. 33 (cross-sectional view of the fitting part 135e and the engaged member 337), the maximum width B of the columnar part 337c extending from the engaged member main body 337a is Similar to the first embodiment, the maximum width A of the two through holes 135h formed at the bottom of the recess 135f of the base 135 is set to be slightly larger than the maximum width A.

  On the other hand, for example, when the claw portion 337d is formed so as to protrude in a direction in which the two columnar portions 337c oppose each other, the minimum width of the two columnar portions 337c is equal to that of the two through holes 135h. By forming it to be the same as or slightly smaller than the minimum width, the engaged member 337 is fixedly attached by the elastic force of the columnar portion 337c.

  As for the length of the columnar portion 337c, the claw portion 337d formed at the front end of the columnar portion 337c when fitted in the recess 135f of the base 135 is outside the through hole 135h formed in the recess 135f. Form to reach up to.

  The claw portion 337d formed at the tip of the columnar portion 337c is formed so as to protrude toward the outside of the opposite columnar portion 337c, and is a surface of the claw portion 337d, and is a boundary between the columnar portion 337c and the columnar portion 337c. Is formed such that the step surface 337e forms an acute angle or perpendicular to the columnar portion 137c, so that the step surface 337e can be hooked on the outer surface of the recess 135f.

  A through-hole 337f that opens in the same direction as the direction in which the insertion portion 337b extends is formed in the center of the engaged member main body 337a.

  The through hole 337f is for inserting a coupling pin 338, which will be described later, and may be formed in a size and shape that allows the coupling pin 338 to be inserted.

  An engagement edge 337i extending in the direction of the axis of the through hole 337f is formed on the side of the through hole 337f where the insertion portion 337b of the engaged member main body 337a is provided.

  By forming the engagement edge 337i, the diameter of the through hole 337f is narrowed. For this reason, it becomes possible to hook a first engaging claw 338f of a coupling pin 338 described later.

  As shown in FIG. 34 (a perspective view of the coupling pin 338), the coupling pin 338 includes a flange portion 338a and an insertion portion 338b, and is formed in a cylindrical shape as a whole.

  The flange portion 338a is formed to have a larger diameter than the through hole 134k formed in the coupling portion main body 134l of the second case 134, and has a size and shape that cannot pass through the through hole 134k. Is formed.

  A columnar insertion portion 338b extending in one direction is formed from the flange portion 338a, and the insertion portion 338b is formed in a hollow shape.

  The insertion portion 338b includes a columnar portion 338d, a first engagement claw 338f, and a second engagement claw 338h.

  A slit 338e is inserted into the insertion portion 338b from a tip thereof to a predetermined position above a second engagement claw 338h described later. Therefore, the distal end of the insertion portion 338b can be bent inward with the slit 338e interposed therebetween. Note that the width and depth of the slit 338e can be appropriately selected according to how much the slit 338e is bent.

  Here, in the present embodiment, the slit 338e is formed only up to the middle of the columnar portion 338d. It becomes difficult to remove from the engaging member 337.

  The columnar portion 338d is formed in a cylindrical shape as a whole, and its outer diameter is substantially the same as the inner diameter of the through hole 337f so that it can be inserted into the through hole 337f formed in the engaged member 337. Alternatively, it is formed to be slightly smaller.

  A first engagement claw 338f is formed at the tip of the columnar portion 338d.

  The first engaging claw 338f is formed so as to protrude outward from the outer periphery of the columnar portion 338d, and gradually expands outward from the tip thereof.

  The first engaging claw 338f is provided with a step surface 338g forming a step with the columnar portion 338d at the boundary with the columnar portion 338d. The step surface 338g is inserted into the insertion portion 338b. The step surface 338g can be hooked on the outer surface of the engaging edge 337i of the engaged member 337 by forming the surface to be an acute angle surface or a vertical surface.

  A second engagement claw 338h is formed between the first engagement claw 338f and the flange portion 338a.

  Here, a slit 338i is formed at the tip and side of the second engagement claw 338h, and the insertion portion 338b in which the second engagement claw 338h is formed can be bent inward. Has been.

  The second engagement claw 338h allows the coupling pin 338 to pass through the through hole 134k formed in the coupling portion main body 134l of the second case 134, and the second engagement claw 338h is connected to the coupling portion main body 134l. The coupling pin 338 is formed at a position where it can be fixed to the coupling portion main body 134l.

  The second engaging claw 338h is formed so as to protrude outward from the outer periphery of the columnar portion 338d, and gradually extends outward from the tip.

  The first engaging claw 338f is formed with a step surface 338j that forms a step with the columnar portion 338d at the boundary with the columnar portion 338d. The step surface 338j is inserted into the insertion portion 338b. The step surface 338j can be hooked on the outer surface of the coupling portion main body 134l of the second case 134 by forming an acute angle surface or a vertical surface.

  The method of using the engaged member 337 and the coupling pin 338 in the present embodiment configured as described above is shown in FIG. 35 (the coupling portion main body 134l of the second case 134, the fitting portion 135e of the base 135, A description will be given using a cross-sectional view in a state where the engaging member 337 and the coupling pin 338 are connected.

  As shown in FIG. 35, the insertion portion 337b formed in the engaged member 337 is inserted into the through hole 135h formed in the concave portion 135f of the base 135, and the claw portion 337d passes through the through hole 135h and the base. The engaged member 337 is fitted into the recess 135f formed in the fitting portion 135e of the base 135 until the position penetrating the 135 is reached.

  Then, the substrate case 132 is attached to the base 135 so that the through hole 134k formed in the coupling portion main body 134l of the second case 134 and the through hole 337g formed in the engaged member 337 communicate with each other. The coupling pins 338 are inserted into these through holes 134k and 337g.

  Then, the first engagement claw 338f of the coupling pin 338 is caught by the engagement edge 337i formed on the engaged member 337, and the second engagement claw 338h is attached to the coupling portion main body 134l of the second case 134. Try to get caught.

  Thus, by attaching the main board 131 accommodated in the board case 132 to the base 135, the engaged member 337 is caught in the recess 135 f of the base 135, so that the board case 132 is placed above the base 135. In addition, since the engaged member 337 and the coupling pin 338 are connected to the base 135, the engaged member 337 does not move even if the engaged member 337 is removed from the base 135. Since it is caught by the coupling part 134j, the substrate case 132 cannot be removed from the base 135 unless the bridge part 134m connecting the coupling part main body 134l is cut.

  In the present embodiment, the first engagement claw 338f and the second engagement claw 338h do not flex in conjunction with each other. Since the engagement of the second engagement claw 338h is maintained in the substrate case 132, the coupling pin 338 is not removed, and the safety is improved.

  Further, since the base 135 is rotatably connected to the mounting portion 136 at the lower end portion thereof, the base 135 can be rotated away from the mounting portion 136 without removing the substrate case 132 from the base 135. By doing so, the back side of the substrate 131 accommodated in the substrate case 132 and the back side of the second case 134 can be confirmed.

  In the embodiment described above as well, the bridge portion 134m of the coupling portion 134j is cut, and the claw portion 337d of the engaged member 337 is bent inward from the back surface of the base 135 to be formed in the concave portion 135f. By extracting the insertion portion 337b from the through-hole 135h, the coupling pin 338, the engaged member 337, and the coupling portion main body 134l can be extracted from the opening 133j of the first case 133 to the front surface of the substrate case 132. By pulling out, the substrate case 132 can be removed by sliding it above the base 135.

  Further, the coupling pin 338 extracted from the opening 133j of the first case 133 and the engaged member 337 can be removed by bending the first engagement claw 338f of the coupling pin 338 inward, Further, since the coupling pin 338 and the coupling portion main body 134l can be removed by bending the second engagement claw 338h of the coupling pin 338 to the inside thereof, the engaged member 337 and the coupling pin 338 You can take them out and use them again.

  The coupling pin 338 according to the above embodiment is a portion where the second engagement claw 338h is formed even if the insertion portion 338b of the portion where the first engagement claw 338f is formed is bent inward. The insertion portion 338b of FIG. 6 is provided with a slit 338i so as not to bend, but the present invention is not limited to such a mode. For example, as shown in FIG. 36 (perspective view of the coupling pin 438). Like the coupling pin 438, the columnar portion 438d in which the first engagement claw 438f and the second engagement claw 438h are formed is continuous, and the first engagement claw 438f is formed. When the portion of the insertion portion 438b is bent inward, the portion of the insertion portion 438h in which the second engagement claw 438h is formed can also be bent inward.

  Even in such a case, the second engagement claw 438h is formed to have a larger diameter than the first engagement claw 438f, and the portion where the first engagement claw 438f is formed. Even if the insertion portion 438b is bent inward, the second engagement claw 438h is prevented from being detached from the coupling portion 134j of the second case 134.

  Further, in the coupling pin 338 according to the above embodiment, the positions where the first engagement claws 338f and the second engagement claws 338h are formed are offset in the circumferential direction and the insertion direction. The direction in which the insertion portion 338b in the portion where the engagement claw 338f is formed is bent and the direction in which the insertion portion 338b in the portion where the second engagement claw 338h is formed are substantially perpendicular. For example, as shown in FIG. 37 (a perspective view of the coupling pin 538), the first engagement claw 538f and the second engagement are formed. The claw 538h is arranged in a straight line, the direction in which the insertion portion 538b of the portion where the first engagement claw 538f is formed is bent, and the insertion portion of the portion where the second engagement claw 538h is formed The direction to bend 538b is almost the same. It is also possible to urchin formed.

  Next, a third embodiment of the present invention will be described with reference to FIGS.

  FIG. 38 is an exploded perspective view of the main controller 130 according to the third embodiment of the present invention.

  As shown in the figure, the main controller 130 includes a main board 131, a board case 132, a base 635, a mounting portion 136, and a coupling pin 638.

  As shown in FIG. 38, the base 635 in this embodiment includes a planar rear surface 135a standing on the back plate 11c side, a bottom surface 135b standing upright from the lower portion of the rear surface 135a, and a side of the rear surface 135a. Since the fitting portion 635e formed on the rear surface 135a is different from the first embodiment, the fitting portion 635e is here. explain.

  As shown in FIG. 39 (a cross-sectional view of one fitting portion 635e taken along line 39-39 in FIG. 38), the fitting portion 635e includes a recess 635f formed on the surface of the rear surface 135a and the recess. And a through hole 635i formed in the bottom of 635f.

  Here, regarding the size and shape of the recess 635f, a second engagement claw 638h formed on a coupling pin 638, which will be described later, is accommodated in the recess 135f, and the second engagement claw 638h is inserted into the second engagement claw 638h. What is necessary is just to select suitably in the range which can be hooked on the coupling part 134j currently formed in the case 134 of.

  In the present embodiment, a through hole 635i is formed at the bottom of the recess 635f. The size and shape of the through hole 635i may be appropriately selected within a range in which a first engagement claw 638f formed on a coupling pin 638, which will be described later, can be passed through and hooked on the outer surface of the recess 635f.

  FIG. 40 is a perspective view of the coupling pin 638 used in the present embodiment.

  As shown in the figure, the coupling pin 638 includes a flange portion 638a and an insertion portion 638b, and is formed in a cylindrical shape as a whole.

  An insertion portion 638b extending in one direction is formed from the flange portion 638a, and the insertion portion 638b is formed in a hollow shape.

  The insertion portion 638b includes a columnar portion 638d, a first engagement claw 638f, and a second engagement claw 638h.

  A slit 638e is inserted into the insertion portion 638b from the tip thereof to a predetermined position. Therefore, the distal end of the insertion portion 638b can be bent inward with the slit 638e interposed therebetween. Note that the width and depth of the slit 638e can be appropriately selected depending on how much the slit 638e is bent.

  The columnar portion 638d is formed in a columnar shape as a whole, and the outer diameter thereof can be inserted into the through hole 134k formed in the coupling portion main body 134l of the second case 134. It is formed to be substantially the same as or slightly smaller than the inner diameter of 134k.

  A first engagement claw 638f is formed at the tip of the columnar portion 638d.

  The first engaging claw 638f is formed so as to protrude outward from the outer periphery of the columnar portion 638d, and gradually extends outward from the tip.

  A step surface 638g that forms a step with the columnar portion 638d is formed on the boundary surface between the first engaging claw 638f and the columnar portion 638d. 638g is formed to be an acute angle surface or a vertical surface with respect to the columnar portion 638d, so that the step surface 638g can be hooked on the outer surface of the concave portion 635e of the base 635.

  A second engagement claw 638h is formed between the first engagement claw 638f and the flange portion 638a.

  Here, the second engagement claw 638h is continuous with the columnar portion 638d where the first engagement claw 638f is formed, and the insertion portion 638b of the portion where the first engagement claw 638f is formed. Is bent inward, so that the insertion portion 638b of the portion where the second engaging claw 638h is formed can also be bent inward.

  The second engaging claw 638h is inserted into the through hole formed in the connecting portion 134i of the second case 134 when the connecting pin 638 is inserted into the peripheral edge of the through hole. The coupling pin 638 is formed at a position where the coupling pin 638 can be fixed to the coupling part 134i.

  The second engaging claw 638h is formed so as to protrude outward from the outer periphery of the insertion portion 638b, and gradually extends outward from the tip thereof.

  A step surface 638i that forms a step with the insertion portion 638b is formed on the surface of the second engaging claw 638h and at the boundary with the insertion portion 638b. Is formed so as to be substantially vertical to the insertion portion 638b, so that the stepped surface 638i can be hooked on the coupling portion main body 134l of the second case 134.

  41. The usage method of the base 635 and the coupling pin 638 in the present embodiment configured as described above is shown in FIG. A cross-sectional view in a connected state will be described.

  As shown in FIG. 41, the substrate case 132 is attached to the base 635 so that the through hole 134k formed in the coupling portion main body 134l of the second case 134 and the fitting portion 635e of the base 635 face each other. The coupling pin 638 is inserted into the through hole 134k of the coupling portion main body 134l of the second case 134.

  Then, the first engagement claw 638f of the coupling pin 638 passes through the through hole 635i formed in the recess 635f of the base 635 and is caught outside the base 635, and the second engagement claw 638h is the second case. It is made to catch on 134 coupling part main body 134l.

  In this way, by attaching the main board 131 accommodated in the board case 132 to the base 135, the coupling pin 638 is caught in the recess 635 f of the base 635, so that the board case 132 is slid above the base 635. In addition, even if the first engagement claw 638f of the coupling pin 638 is removed from the base 635, the second engagement claw 638h is caught by the coupling portion main body 134l of the second case 134. The connecting pin 638 cannot be removed, and eventually, the substrate case 132 cannot be removed from the base 135 unless the bridge portion 134m connecting the connecting portion main body 134l is cut.

  In the embodiment described above, the bridge portion 134m of the coupling portion 134j is cut, and the first engagement claw 638f of the coupling pin 638 is bent inward from the back surface of the base 635, so that the through hole 635i can be bent. The connecting pin 638 can be extracted from the opening 133j of the first case 133 to the front surface of the substrate case 132. By extracting the connecting pin 638 and the connecting portion main body 134l, the substrate case 132 slides above the base 635. Can be removed.

  Further, the coupling pin 638 extracted from the opening 133j of the first case 133 and the coupling part main body 134l expose the second engagement claw 638h of the coupling pin 638. It can be removed by flexing it inward, and the coupling pin 638 can be removed and reused.

  Further, since the base 635 is rotatably connected to the mounting portion 136 at the lower end portion thereof, the base 135 can be rotated away from the mounting portion 136 without removing the substrate case 132 from the base 135. By doing so, the back side of the main board 131 accommodated in the board case 132 and the back side of the second case 134 can be confirmed.

  In the embodiment described above, the recess 635f is formed in the base 635 so that the second engagement claw 638h is hooked on the coupling part 134j of the second case 134. For example, as shown in FIG. 42 (a cross-sectional view in a state where the coupling portion main body 734l of the second case 734, the fitting portion 635e of the base 635, and the coupling pin 638 are coupled). It is also possible to form a recess 734n at a position facing the base 635 of the coupling portion main body 734l of the second case 734 so that the second engagement claw 638h can be hooked on the recess 734n.

  In such a case, as shown in FIG. 43 (a cross-sectional view in a state where the coupling portion main body 734l of the second case 734, the fitting portion 635e of the base 635, and the coupling pin 638 are coupled), for example, The base 735 may be provided with only the through hole 735i in order to provide the recess.

  Further, as shown in FIG. 44 (a cross-sectional view in a state where the coupling portion main body 734l of the second case 734, the fitting portion 735e of the base 735 and the coupling pin 638 are coupled), the second case 834 By providing a through hole 834o that opens laterally in the coupling portion 834j with respect to the direction in which the coupling pin 638 is inserted, the second coupling pin 638h of the coupling pin 638 is hooked in the through hole 834o. It is also possible.

  As shown in FIG. 44, when the through hole 834 is provided, a cover 834p that can cover the through hole 834o is provided in the second case so that the second coupling pin 638h cannot be directly accessed.

  Thus, also in this modification, the second engaging claw 638h of the coupling pin 638 is exposed between the coupling pin 638 and the coupling main body 8341 extracted from the opening 133j of the first case 133. The engaging claw 638h can be removed by bending the engaging claw 638h to the inside, and the connecting pin 638 can be taken out and used again.

  Further, for example, as shown in FIG. 45 (a transverse sectional view in a state where the coupling portion main body 134l of the second case 134, the fitting portion 835e of the base 835, and the coupling pin 838 are coupled), the concave portion of the base 835 is formed. By providing a hook portion 835j for hooking the third engagement claw 838j of the coupling pin 838 inside the 835f, the first as shown in FIG. 46 (the top view of the coupling pin 838). The coupling pin 838 provided with the third engagement claw 838j can be fitted between the engagement claw 838f and the second engagement claw 838h.

  By using such a coupling pin 838, the coupling pin 838 can be fitted into the base 835 more firmly.

  Thus, also in this modification, the second engaging claw 838h of the coupling pin 838 is exposed between the coupling pin 838 extracted from the opening 133j of the first case 133 and the coupling main body 134l. The engaging claw 838h can be removed by bending the engaging claw 838h to the inside, and the coupling pin 838 can be taken out and used again.

  Here, as shown in FIG. 46, the first engagement claw 838f and the third engagement claw 838j are formed in a continuous insertion portion 838b, and the first engagement claw 838f is formed. When the insertion portion 838b formed with is bent in the inner direction, the third engagement claw 838j is also displaced in the direction of the insertion portion 838b.

  In such a case, instead of providing the hook portion 835j inside the concave portion 835f of the base 835, for example, FIG. 47 (the coupling portion main body 934l of the second case 934, the fitting portion 635e of the base 635, and the coupling pin 938). As shown in the cross-sectional view in the state where the two are connected, by providing a concave portion 934p inside the coupling portion 934j of the second case 934, the second coupling claw 938h is hooked on the concave portion 934p, It is also possible to hook the three coupling claws 938j outside the coupling portion 934j.

  In the case shown in FIG. 47, for example, a third engaging claw 938j and a second engaging claw 938j as shown in FIG. 48 (a perspective view of the connecting pin 938). The engagement claw 938h is formed as a continuous member, and when the third engagement claw 938j is bent inward of the insertion portion 938b, the second engagement claw 938h is also directed inward of the insertion portion 938b. It is necessary to bend.

  As described above, also in this modification, the third engaging claw 938j of the coupling pin 938 is exposed between the coupling pin 938 and the coupling body 9341 extracted from the opening 133j of the first case 133. The second engaging claw 938h can be removed by bending the engaging claw 938j to the inside thereof, and the coupling pin 938 can be taken out and used again.
