Description

  The present invention relates to a pachinko gaming machine.

  In conventional pachinko gaming machines, there are many pachinko gaming machines in which the winning rate of balls to a specific variable winning device (including those constituting a starting port, an entrance to a warp route, etc.) changes. As a configuration for changing the winning rate to the variable winning device, a configuration in which the winning rate is changed according to the lottery result display of the variable display unit (sub-digital), or a certain member is driven by a motor or the like to periodically change the winning rate. The structure to change to is well known.

Further, Patent Document 1 below includes a variable winning device that has a special prize opening and a normal prize opening inside and can be converted into a first state that is disadvantageous for the player and a second state that is advantageous to the player. In a pachinko machine, a variable display section that changes every time a ball wins is provided in an accessory, and when the variable display section displays a specific display such as “7”, the special prize opening (V prize opening) And a position in which the position of the normal winning opening is sequentially changed is disclosed.
Japanese Patent No. 2733080

  However, in the configuration in which the winning rate is changed every predetermined time or the configuration in which the winning rate is changed according to the lottery result indicated by the sub-digital, the change tends to be monotonous, and the effect of appealing to the visual perception of the player is not so high. It is difficult to raise the player's interest.

  In view of the above circumstances, it is an object of the present invention to provide a pachinko gaming machine that can enhance the gaming interest by appealing to the player's vision strongly about how the winning rate of the variable winning device changes.

Means for Solving the Problems and Effects of the Invention

In order to solve the above problems, the pachinko gaming machine of the present invention includes a variable winning device in which the winning difficulty of a game ball changes when a movable member is displaced, and a moving stage that moves up and down in the vertical direction along the game board surface. It has, while the plurality allow retention by receiving a game ball that is launched into the game area, the game ball retention device that stationary and gaming ball is provided with a rollable space on the moving stage, moving stage And a swing device that swings the moving stage constantly or intermittently so that the top is unstable . The variable winning device has a maximum open state in which the game ball is most likely to win, and the game ball is the most It is possible to maintain an open state of a minimum open state that is difficult to win and one or more intermediate open states having a difficulty level of winning between the maximum open state and the minimum open state. In the order of the open state, the intermediate open state, and the maximum open state, in accordance with the number or total weight of the game balls stopped on the moving stage of the game ball stop device. The main feature is that the winning difficulty of the variable winning device is changed in stages according to the number or total weight of the gaming balls stopped on the moving stage of the gaming ball stopping device. And In this case, for example, when satisfying the pre Me-determined condition, the game ball during stopping the movement stage can be configured to include a mechanism for forcibly removed from the said moving stage.

  According to the pachinko gaming machine of the present invention, the winning rate of the game balls to the variable winning device changes according to the number or total weight of the game balls stopped at the game ball stopping device. On the other hand, the player can grasp at a glance the number of game balls stopped in the game ball stop device. Therefore, it is possible to strongly appeal to the player's vision about the change in the winning rate of the game balls to the variable winning device by increasing / decreasing the number of game balls stopped at the game ball stopping device. That is, according to the present invention, the structure for changing the winning rate can be provided with novelty, and as a result, the game entertainment can be enhanced. In addition, since the player plays the game so that the number of game balls stopped at the game ball stop device becomes the number (or total weight) at which the winning rate of the variable winning device is the highest, new game characteristics are also born. It should be noted that the total weight of the game balls stopped in the game ball stopping device is approximately proportional to the number of game balls, so it can be considered that there is no substantial difference, but as in the embodiment described later. It is also possible to distinguish these.

  Specifically, the variable winning device has a maximum open state in which game balls are most likely to win, a minimum open state in which game balls are most difficult to win, and a difficulty level of winning between the maximum open state and the minimum open state. It can be configured to be able to maintain one of the one or more intermediate open states. In general, the variable winning device usually exhibits only two states of an open state and a closed state, but in the present invention, it is configured to show at least three levels of winning difficulty. In this way, the winning rate of the variable winning device can be changed in a stepwise manner according to the increase or decrease of the gaming balls stopped at the gaming ball stopping device, and the effect of appealing to the visual perception of the player is also high. As the number of game balls parked on the stopping device increases, the winning rate in the variable winning device increases, and as the number of game balls parked on the stopping device increases, it varies. Either of the cases where the winning rate in the winning device is configured to decrease may be used.

  The game ball stopping device is a member that receives and stops the game ball, and has a first position where the winning rate of the game ball to the variable winning device is minimum, and a winning rate of the game ball to the variable winning device. A support body that is configured to reciprocate between two positions, which is the maximum second position, depending on the number or total weight of game balls that are parked, may be provided. According to this, since the winning rate of the game balls to the variable winning device is changed by the operation of the support body, the background of the change of the winning rate is strongly appealed by the player's vision.

  Further, it is possible to provide an operation conversion means for converting the lifting / lowering operation of the support in the game ball stopping device into the opening / closing operation of the movable member in the variable winning device. By providing such a motion converting means, the reciprocating motion of the support can be directly linked to the opening / closing motion of the movable member in the variable winning device. In this aspect, the displacement of the movable member is limited to the change in the degree of opening of the movable member.

  In a more preferred aspect, the movable member in the variable winning device can be constituted by a pair of movable swaying members that swing in opposite directions. The motion converting means may be a motion converting mechanism configured to include a pivot and a lever that swings about the pivot. In such a motion conversion mechanism, one end of the insulator is connected to the support body in the game ball stopping device, and the other end is connected to the engagement member interlocked with the movable frame, whereby the relationship between the support body and the engagement member is established. The apparatus may be configured so as to have a relationship between a driving body and a driven body that reciprocate in opposite directions in substantially the same plane. As a result, the movable frame of the variable winning device opens and closes according to the reciprocating motion of the support in the game ball stopping device. According to such a configuration, since the movement of the support and the movement of the movable frame are reflected in the player's visual sense, the causal relationship between the two can be strongly impressed.

  The support body can be moved up and down so that the first position is the rising position on the game board surface and the second position is the lowering position. According to this configuration, the weight of the game ball can be hung directly on the support body, and the movable frame can be sufficiently operated by the weight of the game ball.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a schematic front view of a pachinko gaming machine 1 according to the present invention. The pachinko gaming machine 1 has a front glass door 5 attached to the underframe and a game board 3 that is arranged inside the underframe and is covered by the glass door 5. The game board 3 forms a circular game area. Below the game board 3, a ball supply tray 6 is provided. The game balls (pachinko balls) prepared on the ball supply tray 6 are fired toward the game board 3 by a launching device including a handle 7 and the like. The game balls that have reached the game board 3 through the rails jump out of the hitting ball launcher and fall by their own weight while being played by a number of nails drilled in the game board 3.

  The game board 3 is provided with a liquid crystal display unit 11 (variable display unit) near its center. A display device using a light emitting diode instead of a liquid crystal or a reel type display device can also be adopted. Three characters (multiple digits) such as Arabic numerals are displayed on the liquid crystal display unit 11. A start winning device 17 is disposed below the liquid crystal display unit 11. Below the start winning device 17, there are provided an attacker 16 that opens when a jackpot (special prize) is generated, and an out ball collection port 15 for collecting out balls. The start winning device 17 is configured as a variable winning device provided with a pair of movable hanes 21 and 22 (movable members) that swing in opposite directions to each other (see FIG. 4). Similarly, the attacker 16 is configured as a variable winning device whose movable door opens and closes.

  On the left side of the start winning device 17, a game ball stopping device 14 for receiving and stopping the dropped game ball is arranged. The number of game balls to be stopped can be one or a plurality, which is the latter in this embodiment. Between the game ball stopping device 14 and the start winning device 17, an operation conversion mechanism 40 is provided for interlocking the both. Specifically, as shown in FIG. 5, the opening degree of the start winning device 17 changes according to the number or total weight of the gaming balls stopped at the gaming ball stopping device 14, and thereby the start winning device 17. The system has a mechanism that the difficulty level (winning rate) of game balls varies. Details regarding this will be described later.

  FIG. 2 is a block diagram showing a configuration of the game control device 300 of the pachinko gaming machine 1. The game control device 300 is arranged on the back side of the game board 3. As shown in FIG. 2, the game control device 300 of the pachinko gaming machine 1 includes a main control board 100 (main control part), a display control board 105 (display control part), a voice control board 106 (voice control part), and lamp control. It is configured to include a substrate 107 (lamp control unit), a payout control substrate 108 (prize ball control unit), and a firing control substrate 109 (launch control unit). A configuration in which each substrate individually includes a CPU and a memory is common, but is omitted in FIG. Each substrate is supplied with a predetermined voltage of power generated by the power supply circuit unit 110.

  The display control board 105 executes a process for displaying an image on the liquid crystal display unit 11 in accordance with a display control signal input from the main control board 100. The sound control board 106 outputs sound from the speaker 116 according to the input sound control signal. The lamp control board 107 controls blinking of the lamps 117 according to the input lamp control signal. The payout control board 108 controls the payout device 118 according to the input prize ball signal. Thereby, a predetermined amount of prize balls are paid out to the player. The launch control board 109 activates the launch device 119 provided corresponding to the handle 7 in response to the player operating the handle 7 (operation unit). Depending on the amount of operation of the handle 7, it is possible to adjust the ball launching strength (ball flight distance). The main control board 100 includes a CPU 50, a ROM 51 for storing a program, a RAM 52 to which a work area and various counters are assigned, and an input / output port 53, which communicate with each other via a bus. It has become.

  The main control board 100 is electrically connected to a start winning detection unit 170 provided in the start winning device 17 and an attacker winning detection unit 160 attached to the attacker 16. Each detection unit can be configured by a contact type or non-contact type sensor (switch). Further, opening and closing of the attacker 16 configured as a variable winning device is performed by switching excitation / de-excitation of the attacker solenoid 161.

  When a ball is awarded to the start winning device 17 and the attacker 16, a winning detection signal is generated in each winning detection unit 170, 160. The CPU 50 of the main control board 100 acquires a start winning detection signal from the start winning detection unit 170 and executes predetermined electrical processing according to the signal acquisition timing (input timing). The electrical processing includes a winning / losing lottery process for determining whether or not to generate a jackpot in the pachinko gaming machine 1, and a display process for deriving and displaying the lottery result in the winning / failing lottery process on the liquid crystal display unit 11.

  Specifically, a winning / no-win lottery process for determining whether or not to generate a jackpot is executed (CPU 50: winning / no-go lottery means). In response to the result of the lottery process, a symbol to be derived and displayed on the liquid crystal display unit 11 is determined, and a display control signal (control command) based on the determination is input to the display control board 105. The display control board 105 displays a design, a background, etc. on the liquid crystal display unit 11 according to the input display control signal. When it is determined that the jackpot will be generated by the winning / losing lottery process, the jackpot symbol (for example, a doublet such as “777”) is derived and displayed on the liquid crystal display unit 11 after a predetermined fluctuation time. . Similarly, each control board performs control based on a control signal (control command) sent from the main control board 100 for voice output and blinking of the lamp. A program for performing such control is stored in the ROM 51 of the main control board 100 and the ROM (not shown) of each control board.

  In the game control device 300 of the pachinko gaming machine 1 (specifically, the main control board 100), a random number is obtained from the random number generation means in accordance with the timing at which the ball wins the start winning device 17, and the random number becomes a big hit random number. A jackpot winning lottery process is executed by determining whether or not they match. Specifically, a random number counter for success / failure lottery updated at each timer interruption of the CPU 50 is set in a predetermined area (area) of the RAM 52 as a random number generation means, and the random number acquired from the counter is, for example, “7” or the like. If it matches the jackpot random number, it is determined that the jackpot is a big hit. The timer interrupt of the CPU 50 can be designed to occur, for example, every about 2 msec using a counter / timer circuit unit (not shown) provided on the main control board 100, for example. Then, an interrupt program for controlling the pachinko gaming machine 1 can be started with this timer interrupt as a trigger. Note that the “random number” described in the present specification refers to a value extracted with equal probability from the number in a predetermined range.

  FIG. 3 shows details of the game ball stopping device 14. 3A is a schematic front view, and FIG. 3B is a schematic cross-sectional view perpendicular to the game board 3 and the horizontal direction. As shown in FIGS. 3A and 3B, the game ball stop device 14 includes a moving stage 30 that moves up and down in the vertical direction along the plane of the game board 3. The moving stage 30 has an upper surface 30p serving as a ball receiving surface, and is arranged so as to receive and temporarily stop the game ball W that has dropped from above. However, depending on the momentum of the game ball W, there are some that do not stay on the moving stage 30. Further, even if the game ball W has stopped, if it is strongly hit by another game ball W, it falls from the moving stage 30. Therefore, one or more game balls W are not always stopped on the moving stage 30. In addition, a bank-like protrusion 30k is provided on the outer periphery of the upper surface 30p to make it easier to stop the game ball W.

  The game ball stopping device 14 houses a support shaft 32 for elastically supporting the moving stage 30, an elastic member 34 for applying an elastic return force to the support shaft 32, and the elastic member 34 and the game ball. A casing 33 for fixing the stopping device 14 to the game board 3 is provided. One end side of the support shaft 32 is connected to the moving stage 30 integrally or detachably, and the other end side is adjacent to the elastic member disposed in the casing 33. The support shaft 32 is slidable in the vertical direction (vertical direction) along the groove 31 formed in the casing 33. That is, the moving stage 30 sinks downward according to the load received from the game ball W. The elastic member 34 is a spring member. The moving stage 30, the support shaft 32, and the casing 33 can be made of resin.

  FIG. 4 shows a detailed configuration of the start winning device 17. 4A is a schematic front view, FIG. 4B is a schematic cross-sectional view in a direction parallel to the game board 3, and FIG. 4C is a schematic cross-sectional view in a direction perpendicular to the game board 3. The start winning device 17 is configured such that the winning difficulty varies depending on the opening degree of the movable slats 20 and 21. The start winning device 17 includes a casing 22 for holding the proximal ends of the movable slats 20 and 21 and fixing the start winning device 17 to the game board 3. As shown in FIG. 4 (b), the movable blades 20, 21 are gears on the base ends 20 a, 21 a located in the casing 22. An engagement member 23 formed by arranging teeth in a straight line is disposed between the left movable honey 20 and the right movable honey 21. As shown in FIG.4 (c), the end of support shaft 25a, 25b is connected with the engagement member 23 integrally or detachably. Further, the support shafts 25 a and 25 b communicate with a groove 24 formed in the casing 22, and are connected to a slide member 26 disposed on the side opposite to the engagement member 23 so as to be integrated or detachable. With such a configuration, the engaging member 23 can be moved up and down along the groove 24 in the vertical direction.

  The movable splashes 20 and 21 mesh with the teeth of the engaging member 23 on the base ends 20a and 21a side in the form of gears. That is, when the engaging member 23 moves up and down in the vertical direction, the movable slats 20 and 21 swing in the opposite directions around the fixing pins 20k and 21k for fixing themselves to the casing 22 or the like (rotating). Torso). As the engaging member 23, a straight resin rod-like body with teeth cut, for example, a rack can be employed. However, teeth are cut on both sides so as to engage both the left and right movable slats 20 and 21. It may be hollow for weight reduction. It is preferable that the movable slats 20 and 21 and the casing 22 are made of the same resin as the engaging member 23. Note that the game balls W picked up by the movable blades 20 and 21, that is, the game balls W that won the start are guided to the passage 27 and proceed to the game ball collecting unit (not shown).

  As shown in FIG. 5, the pachinko gaming machine 1 converts the reciprocating operation (lifting / lowering operation) of the moving stage 30 in the game ball stopping device 14 into the opening / closing operation of the movable slats 20 and 21 in the start winning device 17. An operation conversion mechanism 42 is provided. The motion conversion mechanism 42 can be composed of a pivot 41 (axis) and a lever 40. One end of the insulator 40 is connected to the moving stage 30 of the game ball stopping device 14, and the other end is connected to the engaging member 23 that interlocks the movable honey 20, 21, and the relationship between the moving stage 30 and the engaging member 23. However, there is a relationship between a driving body and a driven body that reciprocate in opposite directions in substantially the same plane. That is, according to the raising / lowering operation of the moving stage 30, the movable honey 20 and 21 open and close.

  Specifically, the downward movement of the moving stage 30 along the game board surface is converted into the upward movement of the engaging member 23, and the upward movement of the moving stage 30 is converted into the downward movement of the engaging member 23. In conjunction with the upward movement of the engaging member 23, the movable springs 20, 21 perform an opening operation, and in conjunction with the downward movement of the engaging member 23, the movable springs 20, 21 perform a closing operation. That is, the opening operation of the movable honey 20 and 21 is interlocked with the lowering operation of the moving stage 30, and the closing operation of the movable honey 20 and 21 is interlocked with the ascending operation of the moving stage 30.

  The start winning device 17 includes a maximum open state in which the game ball W is most likely to win, a minimum open state in which the game ball W is most difficult to win, and an intermediate open state having a difficulty level of winning between the maximum open state and the minimum open state. Any open state can be maintained. There may be one or more intermediate open states, and the latter is adopted in this embodiment. However, since the weight of the game balls W is substantially constant, the degree of release that is held is substantially gradual. On the other hand, even when the engaging member 23 momentarily moves up and down by a load when the game ball W collides with the moving stage 30 of the game ball stopping device 14, the start winning device 17 performs the opening / closing operation. The movable slats 20 and 21 are not stationary and do not occupy a certain intermediate open state.

  The moving stage 30 is between two positions: a rising position where the winning rate of the game balls W to the start winning device 17 is minimum and a lowered position where the winning rate of the game balls W to the starting winning device 17 is maximum. The reciprocating motion depends on the number (or total weight) of the game balls W stopped on the upper surface 30q. The ascending position and the descending position are the elastic restoring force applied to the moving stage 30 through the support shaft 32. It depends on the size. That is, when the game balls W are not placed on the moving stage 30, the movable slats 20 and 21 are closed to the maximum to minimize the winning rate, while the game stage W is loaded with a certain amount of game balls W (for example, 3 It is desirable that the elastic restoring force applied to the moving stage 30 is adjusted so that the movable honey 20 and 21 are opened to the maximum and the winning rate is maximized. In the present embodiment, since the elastic return force applying means (elastic member 34) for applying the elastic return force is the spring member 34, the adjustment as described above can be performed relatively easily.

  Since the moving stage 30 of the game ball stopping device 14 and the engaging member 23 of the start winning device 17 are both moved in the vertical direction, the connection between them and the lever 40 is as follows. . That is, the lever 40 is connected to the moving stage 30 or the engaging member 23 in such a manner that a through groove is formed in the lever 40 and a connecting member such as a connecting pin is slidably fitted into the through groove. In this way, even when the moving stage 30 and the engagement member 23 move up and down and the distance from the pivot 41 changes, the change can be absorbed by the sliding of the connecting pin in the through groove and move. Smooth movement of the stage 30 and the engaging member 23 is not hindered. Moreover, if the insulator 40 is configured to be extendable and contractible in the longitudinal direction, the same action can be obtained. In the present embodiment, the length of the lever 40 is adjusted equally on the left and right sides of the pivot 41, but when the game ball W is placed on the stage 30, the movable slats 20 and 21 are opened smoothly. The length of the lever 40 can be adjusted on the left and right sides of the pivot 41.

  The structure as described above can be suitably used for a game ball sorting structure (sorting tool) as shown in FIG. The distribution structure 100 has a structure in which the game ball stopping device 14, the variable winning device 17, and the motion conversion mechanism 42 described with reference to FIGS. 3 to 5 are arranged inside the frame 60. The frame 60 is provided with an entrance 65 for a game ball on the upper side, and entry of the game ball W from other than the entrance 65 is prevented. Adjacent to the entrance 65, a guide slope 66 for guiding the game ball W entered from the entrance 65 to either the game ball stop device 14 or the variable prize device 17 is disposed. Further, below the frame body 60, there are provided outlets 61 and 63 and an outlet 62 of the warp route 64 communicating with the variable winning device 17.

  The operation of the game ball sorting structure 100 of FIG. 6 will be described. The game ball W is guided to the inside of the frame body 60 from an inlet 65 formed in the upper part of the frame body 60. The game balls W guided to the inside of the frame body 60 reach the guide slope 66 and are distributed to the left and right. The game balls W distributed to the left side in the figure are guided to the moving stage 30. The game balls W distributed to the right side in the figure are guided to the variable winning device 17. When the game ball W stops on the moving stage 30, the moving stage 30 sinks according to the number of the game balls W, and the degree of opening of the movable slats 20 and 21 constituting the variable winning device 17 increases accordingly. Then, it becomes easy for the game ball W to win the variable winning device 17, that is, the game ball W is easily guided to the warp route 64. The game balls W that won the variable winning device 17 are discharged from the warp route outlet 62 via the warp route 64. On the other hand, the game balls W guided to the moving stage 30 side and the game balls W that have not won the variable winning device 17 are discharged from the discharge ports 61 and 63 to the outside of the frame body 60.

  In the present embodiment, as the number of game balls W that are parked on the moving stage 30 increases, the degree of opening of the movable slats 20 and 21 is increased. Is also suitable. For example, the winning rate of the start winning device 17 may be increased only when a predetermined number or more of game balls W remain on the moving stage 30 (only when three or more balls are placed, the movable slats 20 and 21 are opened). Such). Further, when a predetermined condition is satisfied, a mechanism may be provided for forcibly removing the game ball W that is stopped on the moving stage 30 from the moving stage 30. For example, it is possible to show a method in which the moving stage 30 is hollow and an actuator that vibrates the upper surface 30p is incorporated, or a method in which the moving stage 30 is displaced so that the upper surface 30p is inclined from the horizontal direction. The above conditions include, for example, that a predetermined time has elapsed, a predetermined number or more of game balls W has won a start, a predetermined number of symbol variations on the liquid crystal display unit 11, or a predetermined number or more of games. For example, the ball W is fired, and a predetermined number or more of prize balls are paid out. In order to make the stage unstable, a swinging device that swings the moving stage 30 constantly or intermittently may be provided integrally or separately from the moving stage 30.

  Further, similarly to the moving stage 30, a stage (support) having a function of stopping the game ball W is arranged on the game board 3, and a counting means for counting the number of the game balls W being stopped is provided on this stage, Based on the stationary ball information obtained from the counting means, actuators such as motors and solenoids may be controlled to open and close the movable slats 20 and 21. For example, as shown in FIG. 7 (a), the first gate 70 to which the game ball W falling on the stage 30 ′ should surely pass and only the game ball W that has passed the first gate 70 always pass through the first gate 70. Two gates 71 are provided, and the stage 30 ′ is fixedly disposed between the first gate 70 and the second gate 71 (midway). Each of the gates 70 and 71 is configured to include a detection switch that detects the passage of the game ball W. Then, as shown in FIG. 7B, if the outputs of the detection switches of the gates 70 and 71 are input to the main control board 100 (counting means), the number of balls stopped on the stage 30 ′ can be calculated. it can. Based on the calculation result, the driver 73 is controlled to drive the honey opening / closing motor 74 (preferably a servo motor). It is preferable that the degree of opening of the movable slots 20 and 21 is determined according to the driving amount of the motor 74.

  In addition, as shown in FIG. 8, the moving stage 30 may be provided with (incorporated with) detection means 35 such as a piezoelectric sensor or a photoelectric sensor. The total weight or number of game balls W on the moving stage 30 is detected by those detecting means, and a detection signal output from the detecting means is input to the CPU 50 of the main control board 100 and is stopped on the moving stage 30. The total weight or number of the game balls W is calculated (CPU 50: calculation means). The CPU 50 controls the expansion / contraction device 34 ′ configured by an actuator such as a motor according to the calculated result, controls the position of the moving stage 30 in the vertical direction, and also uses a honey opening / closing motor 74 (FIG. 7B). )) To determine the degree of opening of the movable slats 20 and 21. The telescopic device 34 ′ may be omitted, and the moving stage 30 may be fixedly provided with respect to the game board 3.

  Finally, in the present specification and claims, even when “winning device” is described, it includes a case where no prize balls are paid out as in the game ball sorting structure 100 described in FIG. I refuse to do it.
