In synchronization with the figure game, a plurality of types of effect symbols that can be identified by each are displayed in a variable manner, and a definite effect symbol that is a variable display result is derived and displayed (or simply referred to as “deriving”). It should be noted that, for example, to derive and display various display symbols such as a special symbol and an effect symbol means to display the identification information such as the effect symbol as a stop display (also referred to as a complete stop display or a final stop display) and end the variable display. ..

There are eight types of symbols (alphanumeric characters "1" to "8" or Chinese characters) that are variablely displayed in the "left", "middle", and "right" effect symbol display areas 5L, 5C, and 5R. It may be a number, an English character, eight character images related to a predetermined motif, a combination of numbers, characters or symbols and a character image, and the character image may be, for example, a person or an animal, an object other than these, or an object other than these. , Characters and other symbols, or decorative images showing any other figure). Each of the production symbols is given a corresponding symbol number. For example, a symbol number of "1" to "8" is assigned to each of the alphanumeric characters indicating "1" to "8". The effect symbols are not limited to eight types, and may be any number of types as long as an appropriate number of combinations such as jackpot combinations and missed combinations can be configured (for example, seven types and nine types).

A first reserved storage display area 5D and a second reserved storage display area 5U are set at two locations on the left and right below the display area of the effect display device 5. In the first hold storage display area 5D and the second hold storage display area 5U, the hold storage display for identifiablely displaying the hold storage number (special figure hold storage number) of the variable display corresponding to the special figure game is performed.

Here, the holding of the variable display corresponding to the special figure game is such that the game ball passes through the first starting winning opening formed by the normal winning ball device 6A and the second starting winning opening formed by the ordinary variable winning ball device 6B. It occurs based on the starting prize by (entering). That is, the start condition (also referred to as "execution condition") for executing the variable display game such as the special figure game or the variable display of the effect symbol is satisfied, but the variable display game based on the previously established start condition is being executed. When the start condition that allows the start of the variable display game is not satisfied due to the fact that the pachinko game machine 1 is controlled to the jackpot game state, the variable display corresponding to the established start condition is suspended. Will be done. In this embodiment, the hold memory display generated based on the start winning due to the game ball passing (entering) through the first starting winning opening is displayed as a round white display, and the game ball passes through the second starting winning opening (entering). The hold memory display generated based on the start winning by entering) is similarly made into a round white display.

In the example shown in FIG. 1, the first hold indicator 25A and the second hold indicator 25A and the second for identifiable display of the number of special figure hold storages at the right positions of the first special symbol display 4A and the second special symbol display 4B. A hold indicator 25B is provided. The first hold indicator 25A displays the number of first special figure hold storage so as to be identifiable. The second hold indicator 25B displays the number of second special figure hold storage identifiable.

Below the effect display device 5, a normal winning ball device 6A and a normal variable winning ball device 6B are provided. The ordinary winning ball device 6A forms a first starting winning opening as a starting region (first starting region) that is always kept in a constant open state by, for example, a predetermined ball receiving member. The ordinary variable winning ball device 6B includes an ordinary electric accessory having a movable plate that changes between a closed state of a closed position and an open state of an open position by a solenoid 81 for an ordinary electric accessory shown in FIG. , A second start winning opening is formed as a start area (second start area).

As an example, in the ordinary variable winning ball device 6B, the game ball passes (enters) the second starting winning opening because the movable wing piece is in the vertical position when the solenoid 81 for the ordinary electric accessory is in the off state. It becomes a difficult normal open state. On the other hand, in the normal variable winning ball device 6B, the game ball passes through the second starting winning opening by the tilt control in which the movable wing piece is in the tilting position when the solenoid 81 for the normal electric accessory is on. It will be in an expanded open state where it is easy to enter.

The game ball that has passed (entered) the first starting winning opening formed in the ordinary winning ball device 6A is detected by, for example, the first starting opening switch 22A shown in FIG. The game ball that has passed (entered) the second starting winning opening formed in the normally variable winning ball device 6B is detected by, for example, the second starting opening switch 22B shown in FIG. Based on the detection of the game balls by the first start port switch 22A, a predetermined number (for example, 3) of game balls are paid out as prize balls, and the first special figure reserved memory number is a predetermined upper limit value (for example, "" 4 ”) If it is less than or equal to, the first starting condition is satisfied. Based on the detection of the game balls by the second start port switch 22B, a predetermined number (for example, 3) of game balls are paid out as prize balls, and the second special figure reserved memory number is a predetermined upper limit value (for example, "" 4 ”) If it is less than or equal to, the second starting condition is satisfied. The number of prize balls to be paid out based on the detection of the game ball by the first start port switch 22A and the number of prize balls to be paid out based on the detection of the game ball by the second start port switch 22B. May be the same number or different numbers from each other.

A special variable winning ball device 7 is provided on the right side of the ordinary variable winning ball device 6B. The special variable winning ball device 7 includes a large winning opening door (not shown) that is opened and closed by a solenoid 82 for the large winning opening door shown in FIG. 2, and is opened by the large winning opening door (not shown). A large winning opening (not shown) is formed as a specific area that changes to a closed state.

As an example, in the special variable winning ball device 7, when the solenoid 82 for the large winning opening door is in the off state, the large winning opening door (not shown) closes the large winning opening (not shown) and the game ball is played. Make it impossible to pass (enter) the large winning opening (not shown). On the other hand, in the special variable winning ball device 7, when the solenoid 82 for the large winning opening door is on, the large winning opening door (not shown) opens the large winning opening (not shown) and the game ball. Makes it easier to pass (enter) through the large winning opening (not shown). In this way, the large winning opening as a specific area changes into an open state in which the game ball easily passes (enters) and is advantageous to the player, and a closed state in which the game ball cannot pass (enter) and is disadvantageous to the player. To do. In addition, instead of the closed state in which the game ball cannot pass (enter) the large winning opening (not shown), or in addition to the closed state, a part where the game ball is difficult to pass (enter) through the large winning opening (not shown). An open state may be provided.

The game ball that has passed (entered) the large winning opening is detected by, for example, the count switch 23 shown in FIG. Based on the detection of the game balls by the count switch 23, a predetermined number (for example, 15) of game balls are paid out as prize balls. In this way, when the game ball passes (enters) the large winning opening opened in the special variable winning ball device 7, the game ball passes through another winning opening such as the first starting winning opening or the second starting winning opening. More prize balls will be paid out than when passing (entering). Therefore, if the large winning opening is opened in the special variable winning ball device 7, the game ball can enter the large winning opening, which is a first state advantageous for the player. On the other hand, if the large winning opening is closed in the special variable winning ball device 7, it becomes impossible or difficult for the player to pass (enter) the game ball through the large winning opening to obtain the winning ball. It becomes a disadvantageous second state.

A normal symbol display 20 is provided on the right side of the second hold display 25B. As an example, the ordinary symbol display 20 is composed of 7 segments, dot matrix LEDs, and the like like the first special symbol display 4A and the second special symbol display 4B, and has a plurality of types of identification information different from the special symbol. The normal pattern (also called "normal figure" or "normal figure") is variably displayed (variable display). Such a variable display of a normal pattern is called a normal figure game (also referred to as a "normal figure game").

A normal symbol display 25C is provided above the normal symbol display 20. The normal figure hold indicator 25C is configured to include, for example, four LEDs, and displays the normal figure hold storage number as the number of effective passing balls that have passed through the passing gate 41.

In addition to the above configuration, the surface of the game board 2 (game board surface) is provided with a windmill for changing the flow direction and speed of the game ball and a large number of obstacle nails. Further, as a winning opening different from the first starting winning opening, the second starting winning opening, and the large winning opening, for example, a single or a plurality of general winning openings that are always kept in a constant open state by a predetermined ball receiving member are provided. May be done. In this case, a predetermined number (for example, 10) of game balls may be paid out as prize balls based on the fact that the game balls that have entered any of the general prize openings are detected by the predetermined general prize ball switch. At the lowermost part of the game area 10, an out opening 16 is provided to which a game ball that has not entered any of the winning openings is taken in.

Speakers 8L and 8R for reproducing and outputting sound effects and the like are provided on the upper left and right sides of the game machine frame 3, and an effect LED 9 is provided on the peripheral portion of the game area 10. Decorative LEDs may be arranged around each structure (for example, ordinary winning ball device 6A, ordinary variable winning ball device 6B, special variable winning ball device 7, etc.) in the gaming area 10 of the pachinko gaming machine 1. .. At the lower right position of the glass door frame 50, a ball striking operation handle 52 (operation knob 52) operated by a player or the like to launch a game ball as a game medium toward the game area 10 is provided. For example, the hitting ball operation handle 52 adjusts the elastic force of the game ball according to the amount of operation (rotation amount) by the player or the like. The ball striking operation handle 52 may be provided with a single-shot launch switch or a touch ring (touch sensor) for stopping the drive of the launch motor included in the launch device (not shown).

At a predetermined position of the game machine frame 3 below the game area 10, a game ball paid out as a prize ball or a game ball rented by a predetermined ball lending machine can be supplied to a launching device (not shown). A ball hitting dish (ball hitting dish) is provided to hold (store) the ball.

A stick controller 31A that can be gripped and tilted by the player is attached to the lower part of the front surface of the glass door frame 50. The stick controller 31A includes an operation stick held by the player. Further, a controller sensor unit 35A for detecting a tilting operation with respect to the operation stick may be provided below the stick controller 31A.

Above the stick controller 31A, a push button 31B is provided so that the player can perform a predetermined instruction operation by a pressing operation or the like. The push button 31B may be configured so that the pressing operation from the player can be detected mechanically, electrically, or electromagnetically. A push sensor 35B for detecting a player's pressing operation on the push button 31B may be provided inside the main body of the hitting ball supply plate at the installation position of the push button 31B.

Further, a curtain plate 214, which will be described later, is provided in the lower part of the outer frame 200, and a speaker 8U is built in the curtain plate 214 (not shown).

Next, the progress of the game in the pachinko gaming machine 1 will be schematically described. In the pachinko game machine 1, the normal symbol display 20 executes a variable display of the normal symbol, such that a game ball that has passed through the passing gate 41 provided in the game area 10 is detected by the gate switch 21 shown in FIG. After the normal symbol start condition for starting the normal symbol is satisfied, the normal symbol display is based on the fact that the normal symbol start condition for starting the variable display of the normal symbol is satisfied, for example, the previous normal symbol game is finished. The game of 20 is started.

In this normal symbol game, when a predetermined time, which is the normal symbol fluctuation time, elapses after starting the fluctuation of the normal symbol, the confirmed normal symbol, which is the result of the fluctuation display of the normal symbol, is stopped and displayed (derived display). At this time, if a specific ordinary symbol (symbol per ordinary symbol) such as a number indicating "7" is stopped and displayed as the confirmed ordinary symbol, the variable display result of the ordinary symbol becomes "per ordinary symbol". On the other hand, if a normal symbol other than the normal symbol, such as a number or symbol other than the number indicating "7", is stopped and displayed as a confirmed normal symbol, the variable display result of the normal symbol is "out of normal symbol". Become. In response to the fact that the variation display result of the normal symbol is "per normal figure", the expansion / opening control (tilt control) is performed in which the movable wing piece of the electric tulip constituting the normal variable winning ball device 6B is in the tilt position. However, normal opening control is performed to return to the vertical position after a predetermined time elapses.

After the first starting condition is satisfied, for example, after the game ball that has passed (entered) the first starting winning opening formed in the normal winning ball device 6A is detected by the first starting opening switch 22A shown in FIG. Based on the fact that the first start condition is satisfied due to the end of the previous special figure game or the jackpot game state, the special figure game by the first special symbol display 4A is started. Further, the second starting condition is satisfied because the game ball that has passed (entered) the second starting winning opening formed in the normally variable winning ball device 6B is detected by the second starting opening switch 22B shown in FIG. Later, based on the fact that the second start condition is satisfied due to, for example, the end of the previous special figure game or the jackpot game state, the special figure game by the second special symbol display 4B is started.

In the special symbol game by the first special symbol display 4A and the second special symbol display 4B, when the variation display time as the special symbol variation time elapses after the variation display of the special symbol is started, the variation display of the special symbol is performed. The final confirmed special symbol (special symbol display result) that is the result is derived and displayed. At this time, if a specific special symbol (big hit symbol) is stopped and displayed as a confirmed special symbol, it becomes a "big hit" as a specific display result, and if a special symbol different from the jackpot symbol is stopped and displayed as a confirmed special symbol, " It becomes "off".

After the variable display result in the special figure game becomes a "big hit", the game is controlled to a big hit game state as a specific game state in which a round (also referred to as a "round game") advantageous to the player is executed a predetermined number of times.

In the pachinko gaming machine 1 of the present embodiment, as an example, a special symbol indicating the numbers "3", "5", and "7" is used as a jackpot symbol, and a special symbol indicating the symbol "-" is used as an off symbol. In addition, each symbol such as a big hit symbol or a missed symbol in the special symbol game by the first special symbol display 4A may be a special symbol different from each symbol in the special symbol game by the second special symbol display 4B. However, the special symbol common to both special symbol games may be a jackpot symbol or a missed symbol.

After the big hit symbol showing the numbers "3", "5", and "7" is stopped and displayed as the confirmed special symbol in the special figure game and becomes "big hit" as the specific display result, it is specially variable in the big hit game state. During the period until the predetermined upper limit time (for example, 29 seconds or 0.1 seconds) elapses or the predetermined number (for example, 9) of winning balls is generated at the large winning opening door of the winning ball device 7. , Open the big prize opening. As a result, a round is executed in which the special variable winning ball device 7 is set to the first state (open state) which is advantageous for the player.

The large winning opening door that opens the large winning opening during the execution of the round catches the game ball falling on the surface of the game board 2, and then closes the large winning opening, thereby causing a special variable winning ball device. 7 is changed to a second state (closed state) which is disadvantageous to the player, and one round is completed. The round, which is the opening cycle of the big winning opening, can be repeatedly executed until the number of executions reaches a predetermined upper limit (for example, "16"). Even before the number of rounds to be executed reaches the upper limit, the execution of the round may be terminated when a predetermined condition is satisfied (for example, the game ball has not won a prize in the large winning opening). ..

Of the rounds in the jackpot game state, the round in which the upper limit time for setting the special variable winning ball device 7 to the first state (open state) advantageous to the player is relatively long (for example, 29 seconds) is normally open. Also called a round. On the other hand, a round in which the upper limit time for setting the special variable winning ball device 7 in the first state (open state) is relatively short (for example, 0.1 second) is also referred to as a short-term open round.

In the "left", "middle", and "right" effect symbol display areas 5L, 5C, and 5R provided in the effect display device 5, the special symbol game using the first special symbol in the first special symbol display 4A , Of the special figure game using the second special figure in the second special symbol display 4B, the variable display of the effect symbol is started corresponding to the start of any of the special symbol games. Then, the period from the start of the variable display of the effect symbol to the end of the variable display due to the stop display of the final effect symbol in the "left", "middle", and "right" effect symbol display areas 5L, 5C, and 5R. Then, the variable display state of the effect symbol may become a predetermined reach state.

Here, the reach state is an effect symbol that has not yet been stopped and displayed when the effect symbol that has been stopped and displayed in the display area of the effect display device 5 constitutes a part of the jackpot combination (“reach variable symbol”). (Also referred to as) is a display state in which the fluctuation is continuous, or a display state in which all or part of the effect symbols are fluctuating in synchronization while forming all or part of the jackpot combination. Specifically, some of the “left”, “middle”, and “right” effect symbol display areas 5L, 5C, and 5R (for example, the “left” and “right” effect symbol display areas 5L, 5R, etc.) are preliminarily used. When the effect symbol (for example, the effect symbol indicating alphanumeric characters of "7") that constitutes the specified jackpot combination is stopped and displayed, the remaining effect symbol display area (for example, "medium" effect) that has not yet been stopped is displayed. In the symbol display area 5C, etc.), the effect symbol is fluctuating, or the effect symbol is a big hit in all or part of the effect symbol display areas 5L, 5C, 5R of "left", "middle", and "right". It is a display state that fluctuates synchronously while forming all or part of the combination.

In addition, in response to the reach state, the fluctuation speed of the effect symbol is reduced, or a character image (effect image imitating a person or the like) different from the effect symbol is displayed in the display area of the effect display device 5. By changing the display mode of the background image, reproducing and displaying a moving image different from the effect symbol, or changing the variation mode of the effect symbol, a different effect operation than before the reach state is executed. May be done. Such an effect operation such as a character image display, a change in the display mode of the background image, a reproduction display of the moving image, and a change in the variation mode of the effect symbol is called a reach effect display (or simply a reach effect). In the reach effect, not only the display operation on the effect display device 5, but also the audio output operation by the speakers 8L, 8R, 8U, the lighting operation (blinking operation) on the light emitting body such as the effect LED 9, and the like are set as the reach state. It may be included that the operation mode is different from the operation mode before the above.

As the effect operation in the reach effect, a plurality of types of effect patterns (also referred to as "reach patterns") having different operation modes (reach modes) may be prepared in advance. And, in each reach mode, the possibility of becoming a "big hit" (also referred to as "reliability" or "big hit reliability") is different. That is, the possibility that the variable display result will be a "big hit" can be different depending on which of the plurality of types of reach effects is executed.

When the special symbol that is the out-of-order symbol is stopped and displayed (derived) as the finalized special symbol in the special symbol game, the variable display state of the effect symbol does not become the reach state after the variable display of the effect symbol is started. In some cases, a definite effect symbol that is a predetermined non-reach combination may be stopped and displayed. Such a variable display mode of the effect symbol is referred to as a “non-reach” (also referred to as “normally off”) variable display mode when the variable display result is “off”.

When the special symbol that is the out-of-order symbol is stopped and displayed (derived) as the finalized special symbol in the special symbol game, the variable display state of the effect symbol becomes the reach state after the variable display of the effect symbol is started. Correspondingly, after the reach effect is executed or the reach effect is not executed, the final effect symbol which is a predetermined reach-out combination may be stopped and displayed. Such a variation display result of the effect symbol is referred to as a variation display mode of "reach" (also referred to as "reach loss") when the variation display result is "out of reach".

When the jackpot symbol indicating the number "3" is stopped and displayed as the confirmed special symbol in the special symbol game, it corresponds to the fact that the variable display state of the effect symbol is in the reach state. Then, after the predetermined reach effect is executed, the definite effect symbol which is the predetermined normal jackpot combination (also referred to as “non-probability variation jackpot combination”) among the plurality of types of jackpot combinations is stopped and displayed. In addition, the non-probability change jackpot combination may be stopped and displayed as a final effect symbol without executing the reach effect.

The definite effect symbols that are usually the jackpot combination (non-probability variation jackpot combination) are variablely displayed in the effect symbol display areas 5L, 5C, and 5R of "left", "middle", and "right" in the effect display device 5, for example. Among the effect symbols whose symbol numbers are "1" to "8", any one of the effect symbols whose symbol numbers are even numbers "2", "4", "6", and "8" is "left", "" It suffices as long as it is stopped and displayed on a predetermined effective line in each of the "middle" and "right" effect symbol display areas 5L, 5C, and 5R. The effect symbols whose symbol numbers constituting the normal jackpot combination are even numbers "2", "4", "6", and "8" are referred to as ordinary symbols (also referred to as "non-probability variation symbols").

In response to the confirmed special symbol in the special symbol game becoming the normal jackpot symbol, the finalized effect symbol of the normal jackpot combination (non-probability variable jackpot combination) is stopped and displayed after the predetermined reach effect is executed. The variable display mode is referred to as a variable display mode (also referred to as "big hit type") of "non-probability variation" (also referred to as "normal big hit") when the variable display result is "big hit". It should be noted that the normal jackpot combination (non-probability variation jackpot combination) may be stopped and displayed as the finalized effect symbol without executing the reach effect. Based on the fact that the variable display result is "big hit" in the big hit type of "non-probability change", it is controlled to the normally open big hit state, and after the end, the time reduction control (time reduction control) is performed. By performing the time reduction control, the fluctuation display time (special figure fluctuation time) of the special symbol in the special figure game is shortened as compared with the normal state. In the time saving control, as will be described later, the so-called electric chew support is implemented in which the winning frequency of the normal symbol is increased and the winning frequency of the normal variable winning ball device 6B is increased. Here, the normal state is a normal game state different from a specific game state such as a big hit game state, and is an initial setting state of the pachinko gaming machine 1 (for example, after the power is turned on, such as when a system reset is performed). The same control as the state in which the initialization process is executed) is performed. In the time saving control, one of the conditions that the special figure game is executed a predetermined number of times (for example, 100 times) after the end of the big hit game state and that the variable display result becomes "big hit" is satisfied first. Sometimes you just have to quit.

As a confirmed special symbol in the special symbol game, when the probabilistic jackpot symbol such as the special symbol indicating the numbers "5" and "7" is stopped and displayed among the special symbols that are the jackpot symbols, the variable display state of the effect symbol is displayed. In response to the fact that the player is in the reach state, after the same reach effect as in the case where the variation display mode of the effect symbol is "normal" is executed, the predetermined probability variation jackpot combination among the plurality of types of jackpot combinations is used. The finalized effect symbol may be stopped and displayed. It should be noted that the probabilistic jackpot combination may be stopped and displayed as a finalized effect symbol without executing the reach effect. The definite effect symbol that is a probabilistic jackpot combination is, for example, the symbol number that is variablely displayed in the effect symbol display areas 5L, 5C, and 5R of "left", "middle", and "right" in the effect display device 5 is "1". ~ Of the "8" production symbols, the production symbols whose symbol numbers are "5" or "7" are in the "left", "middle", and "right" production symbol display areas 5L, 5C, and 5R. Anything may be used as long as it is aligned on a predetermined effective line and stopped and displayed. The effect symbol whose symbol number constituting the probability variation jackpot combination is "5" or "7" is called a probability variation symbol. When the probabilistic jackpot symbol is stopped and displayed as the confirmed special symbol in the special symbol game, the confirmed effect symbol, which is usually a jackpot combination, may be stopped and displayed as a variable display result of the effect symbol.

Regardless of whether the finalized production symbol is a normal jackpot combination or a probabilistic jackpot combination, the variable display mode in which the probabilistic jackpot symbol is stopped and displayed as the finalized special symbol in the special symbol game has a variable display result of "big hit". It is also referred to as a "probability variation" variation display mode (also referred to as "big hit type") in the case. In this embodiment, among the jackpot types of "probability change", the normal open jackpot state is controlled based on the fact that the variable display result of "5" and "7" is "big hit" as the confirmed special symbol. After that, probability fluctuation control (probability variation control) is performed together with time reduction control.

By performing these probability variation controls, the probability that the variable display result (special figure display result) becomes a "big hit" in each special figure game is improved so as to be higher than in the normal state. The probability variation control may be terminated when the condition that the variation display result becomes "big hit" after the end of the big hit game state and the control is performed again in the big hit game state is satisfied. Similar to the time reduction control, the probability variation control is terminated when a predetermined number of special figure games (for example, 100 times, which is the same as the time reduction number, or 90 times, which is different from the time reduction number) are executed after the end of the jackpot game state. You may. In addition, even if the probability change control is terminated when the "probability change fall" decision to end the probability change control is made in the probability change fall lottery that is executed every time the special figure game is started after the end of the jackpot game state. Good.

When the time reduction control is performed, the normal symbol display 20 controls the fluctuation time of the normal symbol (normal symbol fluctuation time) in the normal symbol game to be shorter than that in the normal state, and the fluctuation of the normal symbol in each normal symbol game. Control to improve the probability that the display result will be "per normal" compared to the normal state, tilt control of the movable wing piece in the normal variable winning ball device 6B based on the variable display result being "per normal" The second is to make it easier for the game ball to pass (enter) the second start winning opening, such as control to make the tilt control time to be longer than in the normal state and control to increase the number of tilts than in the normal state. Control (electric chew support control) that is advantageous to the player is performed by increasing the possibility that the starting condition is satisfied. In this way, the control that makes it easier for the game ball to enter the second start winning opening due to the time saving control, which is advantageous for the player, is also called a high opening control. As the high open control, any one of these controls may be performed, or a plurality of controls may be combined and performed.

By performing the high opening control, the frequency of the second start winning opening being in the expanded open state is increased as compared with the case where the high opening control is not performed. As a result, the second start condition for executing the special figure game using the second special figure on the second special symbol display 4B becomes easy to be satisfied, and the special figure game can be executed frequently. The time until the variable display result becomes a "big hit" is shortened. The period during which the high opening control can be executed is also referred to as the high opening control period, and this period may be the same as the period during which the time saving control is performed.

The gaming state in which both the time saving control and the high opening control are performed is also called a time saving state or a high base state. Further, the gaming state in which the probability change control is performed is also referred to as a probability change state or a high probability state. A gaming state in which time reduction control and high opening control are performed together with probability variation control is also called a high probability high base state. Although not set as the game state to be controlled in this embodiment, the probability change state in which only the probability change control is performed and the time saving control and the high opening control are not performed is also referred to as a high probability low base state. In addition, only the gaming state in which the time reduction control and the high opening control are performed together with the probability change control is sometimes referred to as a "probability change state", and in order to distinguish it from the high probability low base state, it may be referred to as a time reduction probability change state. On the other hand, a probabilistic state (high-probability low-base state) in which only probabilistic control is performed and time-saving control or high-opening control is not performed may be a probabilistic state without time-saving in order to distinguish it from a high-probability high-base state. The time saving state in which the time saving control or the high opening control is performed without the probability change control is also called the low probability high base state. The normal state in which the probability change control, the time reduction control, and the high opening control are not performed is also referred to as a low probability low base state. When at least one of the time saving control and the probability variation control is performed in a game state other than the normal state, the probability that the special figure game can be executed frequently and that the variation display result in each special figure game becomes a "big hit". Is increased, which is advantageous for the player. A gaming state that is advantageous for a player different from the jackpot gaming state is also called a special gaming state.

The pachinko game machine 1 is equipped with various control boards such as a main board 11, an effect control board 12, a voice control board 13, and an LED control board 14, as shown in FIG. 2, for example.

The cover member 802 is made of a transparent thermoplastic synthetic resin, and is composed of a base plate 821a formed in a substantially rectangular shape in a vertically long shape, and side walls 821b to 811e erected on the upper, lower, left and right sides toward the back side. , It is formed in a box shape that opens toward the back side.

At the upper half angle portion on the back surface (inner surface) of the base plate 821a, screw holes 823 into which screws 822 for mounting the first substrate 12A are screwed are projected at three places, and three positioning convex portions 824 are provided. It is projected in a place. Further, in the lower half-angle portion, screw holes 826 into which screws 825 for mounting the second substrate 12B are screwed are projected at three locations, and positioning convex portions 827 are projected at two locations. ..

In this embodiment, the first board 12A and the second board 12B, which are the effect control boards 12, are configured to be attached to the cover member 802 with screws, but are attached to the base member 801 side. Alternatively, it may not be attached to either the base member 801 or the cover member 802. Further, it may be attached to either the base member 801 or the cover member 802 with an attachment member other than the screw.

Further, a plurality of heat dissipation holes 829 are formed at positions corresponding to the upper portions of the first substrate 12A and the second substrate 12B on the base plate 801a. Further, bosses 828 are projected at two positions on the left and right at positions corresponding to the upper ends of the second substrate 12B on the back surface of the base plate 801a.

At the left and right positions on the upper side wall 821b, locking hooks 831 having a substantially upward U-shape in the side view to be locked to the locking bar 805 of the base member 801 are formed. Further, locking pieces 832 that are inserted into and locked into the locking holes 807 of the base member 801 are formed at the left and right positions on the lower side wall 821c.

Locking portions 833 that are locked to the locked portions 808 of the base member 801 are formed at substantially the center positions of the left and right side walls 821d and 821e in the longitudinal direction of the outer surface, and one-way screws are formed at the lower positions of the outer surface. A mounting piece 834 having a mounting hole 834a formed in the 809 is mounted via a connecting piece. Further, a connector opening 837 through which a wiring side connector (not shown) of the wiring connected to the effect display device 5 is inserted is formed at a substantially central position of the left side wall 821d in the longitudinal direction.

Further, on the upper left side of the base plate 821a, a switch opening 835 for allowing the volume adjusting switch 835a mounted on the first substrate 12A to face the outside is formed. Further, on the upper right side, a vertically rectangular connector opening 836 for allowing various substrate-side connectors KCN10 mounted on the first substrate 12A to face the outside is formed along the right side. Further, the left side wall 821d is formed with a connector opening 837 for allowing the substrate-side connector KCN5 mounted on the second substrate 12B to face the outside.

Further, as shown in FIG. 12, the base plate 801a is formed with a plurality of mark portions 840, 841 formed by a mold or the like when the base member 801 is molded. For example, the mark portion 840 is formed by a gate mark formed at the inflow port of the resin melted during molding (see the halftone dot circle in FIG. 12), and the mark portion 841 is made of a molded product with gold. It is formed by the ejector pin traces pressed by the ejector pins for removal from the mold (see halftone dot circles in FIG. 12). The mark portions 840 and 841 are set in portions having a large mold release resistance (resistance when the product is peeled from the mold) such as the boss 803, 804, the rib 804a, the rib 815, and the side walls 801b to 801e. Therefore, the positions of the boss 804, the rib 804a, the step portion 814b'and the rib 815 as the obstructing portions in the vicinity thereof can be specified from the outside of the transparent substrate case 800 by the mark portions 840 and 841. ..

In this way, the gate marks and ejector pin marks formed when the base member 801 is molded are located on the outside of the substrate case 800 at the positions of the boss 804, the rib 804a, the step portion 814b'and the rib 815 as the case side obstructing portion. By also serving as the mark portions 840 and 841 that can be identified from the above, it is not necessary to separately form a convex portion or a concave portion in the mold in order to form the mark portion, so that the manufacturing cost can be reduced. In the present embodiment, the mark portions 840 and 841 are formed by the gate marks and ejector pin marks formed when the base member 801 is molded, but the present invention is not limited to this, and the above is not the case. Separately from the mark portions 840 and 841 formed by the gate mark and the ejector pin mark, a convex portion, a concave portion, or the like may be formed on the mold to form the mark portion.

Further, as shown in FIG. 12, since the heat radiation hole 829 is formed at a position other than the position facing the sockets 700A, 700B, 700C, foreign matter such as a wire is inserted from the heat radiation hole 829 to insert a foreign substance such as a wire into the ROM 121, the character ROM 126, or the like. Unauthorized acts such as unauthorized modification of the wire are suppressed.

Electronic components such as the effect control CPU 120 and VDP are mounted on the rear surface 12b of the first substrate 12A. Further, a substrate-side connector KCN1 is provided along the lower side, and a plurality of substrate-side connectors KCN10 are arranged in a row along the right side. A substrate-side connector KCN5 is provided on the left side.

On the front surface 12f of the second substrate 12B, electronic components such as a ROM 121 and a plurality of (two in this embodiment) character ROM 126 are mounted. The ROM 121 and the character ROM 126 are mounted on the second substrate 12B via a socket described later. Further, a board-side connector KCN2 connected to the board-to-board is provided on the board-side connector KCN1 along the upper side.

The first substrate 12A and the second substrate 12B, which are the effect control substrates 12, are attached to the front surface side (case inner surface side) of the cover member 802 configured in this way. Here, how to attach the first substrate 12A and the second substrate 12B to the front surface of the cover member 802 will be described with reference to FIGS. 4 and 5. First, the second substrate 12B is attached to the cover member 802 with screws 825. Install on the front. Next, the board-side connector KCN1 of the first board 12A is connected to the board-side connector KCN2 of the second board 12B, and is attached to the front surface of the cover member 802 with screws 822. The first substrate 12A and the second substrate 12B may be attached to the cover member 802 with screws in a connected state.

Next, a method of sealing the substrate case 800 will be described with reference to FIG.

First, the tip of the locking hook 831 of the cover member 802 to which the first substrate 12A and the second substrate 12B are assembled is inserted into the opening formed between the locking bar 805 and the side wall 801b of the base member 801. (See FIG. 8 (A)). Here, since the locking hook 831 is formed in an L shape in a side view, the tip of the locking hook 831 is locked to the base member 801 unless the cover member 802 is placed in an upright posture substantially orthogonal to the base member 801. It cannot be inserted into the opening formed between the bar 805 and the side wall 801b. That is, when the substrate case 800 is opened, the cover member 802 cannot be separated from the base member 801 unless the cover member 802 is rotated about 90 degrees until it is in an upright posture substantially orthogonal to the base member 801. , Can be difficult to open.

Next, the locking hook 831 is locked to the locking bar 805, the cover member 802 is tilted around the locking bar 805, and the cover member 802 is placed in the upper opening of the base member 801. At this time, the locking piece 832 of the cover member 802 is made to enter the inside of the side wall 801c of the base member 801 (see FIG. 8B).

Then, the cover member 802 is slid downward with respect to the base member 801. As a result, the locking piece 832 is locked in the locking hole 807, and the locking portions 833 (see FIGS. 4 and 5) on the left and right sides are engaged with the locked portion 808. Therefore, the locking hook 831 on the upper side of the cover member 802 is locked to the locking bar 805, the locking piece 832 on the lower side is locked to the locking hole 807, and the locking portions 833 on the left and right sides are locked. By engaging with the portion 808, the movement of the cover member 802 with respect to the base member 801 in the detaching direction is restricted, and the opening of the base member 801 is closed by the cover member 802 (see FIG. 8C).

In the assembled state in which the base member 801 and the cover member 802 are assembled in this way, the mounting hole 834a of the cover member 802 matches the screw hole 810 of the base member 801. Therefore, the one-way screw 809 attached to the mounting hole 834a is used. By screwing into the screw hole 810, the substrate case 800 is sealed so as not to be opened without leaving a trace (so-called caulking).

That is, the one-way screw 809 is a conventionally known one-way screw that can be rotated in the mounting direction by a tool such as a screwdriver, but cannot be rotated in the removing direction. Therefore, after the sealed state, for example, the one-way screw 809 is mounted. The sealed state cannot be released and the package cannot be opened unless the substrate case 800 is destroyed by cutting the connecting piece of the piece 834. That is, the one-way screw 809, the mounting piece 834, the mounting hole 834a, and the screw hole 810 are sealed so that the substrate case 800 cannot be opened without leaving a trace after the base member 801 and the cover member 802 are assembled. It constitutes a stopping means.

In this embodiment, as an example of a sealing means for sealing the substrate case so that it cannot be opened without leaving a trace, a mode using a one-way screw 809 has been illustrated, but the present invention is limited to this. Rather, it corresponds to those that cannot be opened unless the part related to the sealing of the substrate case is destroyed once sealed, and those that cannot be opened without leaving any opening marks or scars by opening. For example, a sealing seal or the like that leaves a trace such as breaking when peeled off after being attached once may be applied. In this case, the sealing seal is in the assembled state in which the base member 801 and the cover member 802 are assembled. Can be attached so as to straddle the base member 801 and the cover member 802 to form a sealed state. Further, the sealed state may be formed by using the one-way screw 809 and the sealing seal, or the sealed state may be formed by means other than these (for example, welding and fixing).

Further, in such a closed state, the position corresponding to the substrate side connector KCN1 on the front surface of the first substrate 12A abuts on the boss 803, and the position corresponding to the substrate side connector KCN2 on the back surface of the second substrate 12B is the boss 828. The first substrate 12A and the second substrate 12B are sandwiched from the front and back by the bosses 803 and 828 so that the connection state of the substrate side connectors KCN1 and 2 is not released by the contact with.

Next, sockets 700A, 700B, 700C for connecting ROM 121 and character ROM 126, which are examples of electronic components, to the second substrate 12B will be described with reference to FIGS. 9 to 16. FIG. 9 is an exploded perspective view showing the socket. 10A and 10B are views showing a state in which the engaging portion of the holding member is inserted into the engaging groove of the housing, and FIG. 10B is a state in which the engaging portion is engaged with the engaged portion. 11A to 11C are schematic cross-sectional views showing a state in which the ROM is mounted in the socket. FIG. 12 is a front view of the board case showing the arrangement positional relationship between the base member and the socket. FIG. 13 is a cross-sectional view taken along the line AA of FIG. FIG. 14 is a cross-sectional view taken along the line BB of FIG. 15A and 15B are explanatory views showing an example of a ROM removal status as viewed from above and below. 16A and 16B are explanatory views showing an example of a ROM ejecting state as viewed from the left-right direction.

As shown in FIGS. 9 to 11, the sockets 700A, 700B, and 700C are provided on the front surface 12f of the second substrate 12B, and the ROM 121 and the character ROM 126 are detachably attached so as to be connectable to the second substrate 12B. ing. The socket 700A can be equipped with the ROM 121, and the sockets 700B and 700C can be equipped with the character ROM 126. However, since they are all formed in the same shape, only the socket 700A to which the ROM 121 is mounted will be described below. The description of the sockets 700B and 700C to which the ROM 126 is mounted will be omitted.

Specifically, the socket 700A has a housing 701 formed of a synthetic resin material and capable of mounting the ROM 121, and a plurality of electrode pads 121a arranged side by side in the vertical direction on the left and right sides of the back surface of the ROM 121 to be mounted. It mainly has a contact 702 provided so as to be connectable to the housing 701, and a square frame-shaped holding frame 703 for holding the ROM 121 mounted on the housing 701.

The housing 701 has a box shape that opens forward by a bottom plate portion 710 formed in a rectangular shape when viewed from the front and vertical wall portions 711a to 711d erected along the left and right sides and the upper and lower sides of the bottom plate portion 710, respectively. A mounting portion 710F to which the ROM 121 can be mounted is formed in a portion formed and surrounded by standing wall portions 711a to 711d on the front surface of the bottom plate portion 710. A plurality of groove portions 712L and 712R facing in the left-right direction are formed on the left and right sides of the bottom plate portion 710 in the vertical direction, and contacts 702 are arranged in each of the groove portions 712L and 712R.

A plurality of mounting grooves 713L and 713R are formed on the inner surfaces of the left and right standing wall portions 711c and 711d. The mounting grooves 713L and 713R are composed of an insertion groove portion 713a that opens forward and inward, and a locking groove portion 713b that extends downward from the rear end portion of the insertion groove portion 713a and opens inward, and is viewed from the left and right directions. Is formed as an L-shaped groove.

The contact 702 is formed by bending a metal plate and has elasticity, and is attached to each of the groove portions 712L and 712R. Specifically, the contact 702 is fixed to a fixing portion 702a formed by punching a conductive metal thin plate and fixed to the housing 701, and a leg portion (not shown) connected to the fixing portion 702a and extending downward. It has a connecting portion 702b which is connected to the portion 702a and extends diagonally upward and is provided side by side. The connecting portion 702b is elastically deformed so as to move backward together when pressed downward, and when inserted into each of the groove portions 712L and 712R, the connecting portion 702b projects upward from the upper surface of the bottom plate portion 710. It is arranged like this.

The holding frame 703 is formed in a substantially rectangular frame shape having an opening 720 in the center by injection molding or the like using an electrically insulating resin material, and is formed in an external dimension that can be fitted in the housing 701. A plurality of locking protrusions 721L and 721R are formed on the left and right outer surfaces of the holding frame 703. The locking projections 721L and 721R are composed of a base portion 721a extending in the front-rear direction and a locking portion 721b extending upward and downward from the rear end portion of the base portion 721a, respectively, and the mounting groove 713L formed in the housing 701. The same number is formed at the position corresponding to 713R.

As shown in FIG. 11A, the holding frame 703 configured in this way is attached to the housing 701 so as to cover the ROM 121 from the front. At this time, as shown in FIGS. 10 (A) and 11 (B), after inserting the locking projections 721L and 721R of the holding frame 703 into the mounting grooves 713L and 713R of the housing 701, FIGS. As shown in FIG. 11C, by sliding the holding frame 703 downward, the locking portions 721b of the locking protrusions 721L and 721R enter the locking groove portions 713b of the mounting grooves 713L and 713R, and the holding frame The 703 is in a holding state held in the housing 701.

When the holding frame 703 is attached to the housing 701, as shown in FIG. 11C, the ROM 121 is pressed backward by the holding frame 703, and the connecting portion 702b in contact with the electrode pad 121a of the ROM 121 is elastically deformed. Pressed backwards. Further, when the ROM 121 is pressed backward by the holding frame 703, the back surface of the ROM 121 and the front surface of the bottom plate portion 710 are in contact with each other, and the ROM 121 is fixedly held in a state of being mounted on the mounting portion 710F. Therefore, the contact state between the electrode pad 121a of the ROM 121 and the connection portion 702b of the contact 702 is well maintained. By mounting the ROM 121 in the socket 700A in this way, the ROM 121 can be detachably connected to the second substrate 12B.

That is, the holding frame 703 is moved forward and backward along the inner surface of the vertical wall portions 711a to 711d via the mounting grooves 713L and 713R formed on the inner surface of the vertical wall portions 711a to 711d erected on the side of the mounting portion 710F. It is guided so that it can move up and down. Further, the holding frame 703 is held in the housing 701 so that the front surface thereof is substantially flush with the front end surfaces of the standing wall portions 711a to 711d, but is in front of the front end surfaces of the standing wall portions 711a to 711d. It may be arranged so as to protrude or enter behind the front end faces of the standing wall portions 711a to 711d.

As described above, in the socket 700A of the present embodiment, after the locking projections 721L and 721R of the holding frame 703 are inserted into the mounting grooves 713L and 713R of the housing 701, the holding frame 703 is slid downward to be locked. By locking the 721b to the locking groove portion 713b, the holding frame 703 is held in the housing 701 in a state where the ROM 121 is pressed, and the ROM 121 is held in the first state and the first state in which the ROM 121 is mounted on the second substrate 12B. After the frame 703 is slid upward to release the locked state between the locking portion 721b and the locking groove portion 713b, the locking protrusions 721L and 721R are moved forward along the mounting grooves 713L and 713R to move the housing. By taking out from 701, the ROM 121 can be changed to a second state in which the ROM 121 can be taken out in a direction away from the second substrate 12B (for example, forward).

Next, the socket 700A when the second substrate 12B to which the ROM 121 and the character ROM 126 are mounted via the sockets 700A, 700B, 700C is housed in the substrate case 800 and is in a sealed state is based on FIGS. 12 to 16. Will be explained.

As shown in FIGS. 12 to 14, when the effect control board 12 including the first board 12A and the second board 12B is housed in the board case 800, the second board 12B has sockets 700A, 700B, 700C. The base member 801 is arranged so as to face the base plate 801a and substantially parallel to the base plate 801a at a position separated from the base plate 801a. The sockets 700A, 700B, and 700C are arranged side by side on the front surface 12f of the second substrate 12B at predetermined intervals in the left-right direction, and correspond to the region between the step portion 814b and the boss 804 and the rib 804a in the base plate 801a. Placed in position.

For each of the sockets 700A, 700B, and 700C, to explain the socket 700A shown in FIG. 13 as an example, the holding frame 703 and the standing wall portion are in a state where the holding frame 703 is attached to the housing 701 and the ROM 121 is held by the mounting portion 710F. The front ends of 711a to 711d are close to the base plate 801a of the base member 801. Specifically, the distance distance L10 in the front-rear direction from the front ends of the holding frame 703 and the standing wall portions 711a to 711d to the base plate 801a is shorter than the plate thickness dimension L11 of the main body of the ROM 121 (L10 <L11). Further, it is longer than the front-rear dimension L13 of the holding frame 703 (L10> L13).

Here, in a state where the board case 800 in which the effect control board 12 is housed is sealed, for example, the base member 801 and the cover member 802 are forcibly pressed without releasing the sealed state of the board case 800. A gap may be formed between the base member 801 and the cover member 802 by bending it, or the board case 800 provided on the back surface of the pachinko gaming machine 1 may be inconspicuous when viewed from the back surface (for example, on the socket 700A). Foreign matter such as a jig is illegally entered by some method such as making a hole in the corresponding side wall 801b to 801e), the holding frame 703 of the socket 700A is removed from the housing 701, and the ROM 121 is taken out, resulting in unauthorized modification. A case of performing fraudulent acts such as exchanging with a provided ROM will be described.

In order to illegally remove the ROM 121 from the socket 700A, first, as shown in FIGS. 15 and 16, the holding frame 703 is removed from the housing 701 by a jig or the like that has been inserted into the substrate case 800 as described above. The ROM 121 mounted on the mounting portion 710F is moved forward, that is, separated from the mounting portion 710F and passed through the gap between the socket 700A and the base plate 801a of the base member 801 to pass the substrate case 800. It is necessary to approach the side wall and pull out the ROM 121 from the gap between the base member 801 and the cover member 802 or an illegally formed hole.

However, as shown in FIGS. 15A and 16A, standing wall portions 711a to 711d are erected around the mounting portion 710F, and the ROM 121 is mounted from the mounting portion 710F along the second substrate 12B. Since it cannot be moved and taken out, in order to take out the ROM 121 from the mounting portion 710F, the holding frame 703 is first moved to the front base plate 801a side, and then moved in the left-right direction or the upward direction along the base plate 801a. And take it out from the housing 701. Since there are a boss 804 and a rib 804a below and they come into contact with each other, they cannot be moved. Since the front-rear dimension L13 of the holding frame 703 is shorter than the front-rear distance dimension L10 between the front ends of the standing wall portions 711a to 711d and the base plate 801a in the front-rear direction (L10> L13), the ROM 121 is mounted on the standing wall portions 711a to 711d. Can pass through the gap between the front end of the base plate 801a and the base plate 801a.

Next, as shown in FIGS. 15 (B) and 16 (B), the ROM 121 must be moved to the front base plate 801a side, and then moved in the left-right direction or the upward direction along the base plate 801a. However, since the plate thickness dimension L11 of the ROM 121 is longer than the distance between the front end of the standing wall portions 711a to 711d and the base plate 801a in the front-rear direction (L10 <L11), the ROM 121 is attached to the standing wall portions 711a to 711d. It cannot be taken out from the housing 701 by passing through the gap between the front end and the base plate 801a.

In this way, even if the holding frame 703 is taken out from the housing 701 and the ROM 121 is moved forward from the mounting portion 710F with the board case 800 sealed, the side of the mounting portion 710F, that is, the second substrate 12B Since it cannot be moved in the direction along the above, the ROM is taken out from the gap between the side walls 801b to 801e of the base member 801 and the side walls 821b to 802e of the cover member 802, or illegally formed holes, and illegally modified. It becomes difficult to replace the ROM with the ROM and mount it on the mounting unit 710F. Therefore, an illegal act such as exchanging electronic components such as ROM 121 and character ROM 126 mounted on the second substrate 12B housed in the substrate case 800 with a ROM that has been illegally modified without opening the substrate case 800. Can be suppressed.

As described above, in the pachinko gaming machine 1 as an embodiment of the present invention, the first state in which the electronic components such as ROM 121 and the character ROM 126 are mounted on the second substrate 12B of the effect control substrate 12 and the electrons. Sockets 700A, 700B, 700C as mounting tools that can be changed to a second state in which components can be taken out in a direction away from the second board 12B (for example, a perpendicular direction of the front surface 12f of the second board 12B), and a base member. After assembling the substrate case 800 having the 801 and the cover member 802 and accommodating the second substrate 12B, and the base member 801 and the cover member 802, the substrate case is sealed so as not to be opened without leaving a trace. A sealing means for stopping (for example, one-way screw 809, mounting piece 834, mounting hole 834a, screw hole 810, etc.) is provided, and the second substrate 12B has sockets 700A, 700B, 700C as the base plate 801a of the base member 801. The sockets 700A, 700B, and 700C are housed in the board case 800 so as to face each other, and the sockets 700A, 700B, and 700C are provided in the standing wall portions 711a to 711d and the standing wall portions 711a to 711d which are erected on the side of the electronic component mounted on the second substrate 12B. It has a holding frame 703 as a holding portion that is movably guided along the line, and the holding frame 703 presses and holds the electronic component toward the second substrate 12B in the first state, and holds the electronic component in the second state. Electronic components can be taken out from the sockets 700A, 700B, 700C by moving away from the two boards 12B, and the standing wall portions 711a to 711d have the base member 801 at the front end in a state where the second board 12B is housed in the board case 800. Close to the base plate 801a of.

By doing so, when the socket 700A is changed to the second state and the ROM 121 is taken out from the socket 700A while the board case 800 is sealed, the base member is taken out when the ROM 121 is taken out in the direction away from the second board 12B. Since the base plate 801a of 801 is an obstacle and the vertical wall portions 711a to 711d are close to the base plate 801a, the holding frame 703 and ROM 121 can be removed from the tips of the vertical wall portions 711a to 711d, or from the second substrate 12B. Since it is difficult to move the separated ROM 121 along the base plate 801a and pass it between the base plate 801a and the standing wall portions 711a to 711d, the ROM 121 is turned into an invalid ROM without opening the board case 800. It is possible to suppress fraudulent activities such as exchanging.

Further, the socket 700A is changed to the second state because the separation dimension L10 in the front-rear direction between the standing wall portions 711a to 711d and the base plate 801a of the base member 801 is shorter than the plate thickness dimension L11 of the ROM 121. When the ROM 121 is removed, the holding frame 703 and the ROM 121 cannot be passed between the base plate 801a and the standing wall portions 711a to 711d, so that fraudulent activity can be suppressed more preferably.

In this embodiment, in the state where the substrate case 800 is sealed (the state where the second substrate 12B is housed in the substrate case 800), the standing wall portions 711a to 711d are close to the base plate 801a. The present invention is not limited to this, and the separation dimension L10 between the tips of the standing wall portions 711a to 711d and the base plate 801a may be "0", that is, they may come into contact with the standing wall portions 711a to 711d. ..

Further, in this embodiment, when the substrate case 800 is sealed and the standing wall portions 711a to 711d are close to the base plate 801a, the vertical wall portions 711a to 711d and the base plate 801a of the base member 801 are separated in the front-rear direction. The dimension L10 is shorter than the plate thickness dimension L11 of the ROM 121, but the present invention is not limited to this, and the separation dimension L10 is longer than the plate thickness dimension L11 (L10> L11). ) May be.

That is, even when the ROM 121 can be passed between the standing wall portions 711a to 711d and the base plate 801a, the ROM 121 is placed between the standing wall portions 711a to 711d and the base plate 801a as compared with the case where the standing wall portions 711a to 711d are not provided. Since it becomes difficult to pass through, cheating can be suppressed. For example, the separation dimension L10 is preferably shorter than the plate thickness dimension L11, but the separation dimension L10 may be the same as the plate thickness dimension L11, and the separation dimension L10 is larger than the plate thickness dimension L11. It may be slightly longer (for example, about 10 mm).

Further, when the holding frame 703 is attached to the housing 701, the holding frame 703 moves from the tip of the standing wall portions 711a to 711d to the second substrate 12B side and then moves downward along the second substrate 12B from the second substrate 12B. Since the movement in the away direction is restricted, when the socket 700A is changed from the first state to the second state in order to illegally take out the ROM 121 as described above, the holding frame 703 is changed to the second board 12B. After moving along, it is necessary to move in a direction away from the second substrate 12B. That is, it cannot be taken out only by moving it in one direction, and it takes time and effort to perform a two-step operation, so that fraudulent activity can be suppressed more preferably.

Further, in the present embodiment, as described with reference to FIG. 8, the substrate case 800 abuts the cover member 802 against the base member 801 and then slides the cover member 802 downward along the second substrate 12B. By allowing the base member 801 and the cover member 802 to be opened or closed, the holding frame 703 can open or close the base member 801 and the cover member 801 when the socket 700A is changed from the first state to the second state. The present invention is not limited to this, and the holding frame 703 moves the socket 700A from the first state to the second state, although the sliding movement is performed in the same direction as the sliding movement which is the opening / closing operation with the 802. When changing to, the base member 801 and the cover member 802 may be slid and moved in a direction different from the sliding direction (for example, the vertical direction), which is an opening / closing operation (for example, the horizontal direction).

By doing so, when the ROM 121 is removed from the socket 700A, it is necessary to move the holding frame 703 in a direction different from the opening / closing direction of the board case 800, and the taking-out operation of the ROM 121 and the opening / closing operation of the board case 800 are complicated. Therefore, fraudulent activity can be suppressed more preferably.

Further, while the substrate case 800 is slid upward when the substrate case 800 is opened, the holding frame 703 may be slid downward with respect to the housing 701 when the socket 700A is in the second state. That is, even if the holding frame 703 is not slid in a direction different from the opening / closing direction of the substrate case 800, at least the direction in which the holding frame 703 is slid when the substrate case 800 is opened is different from the direction in which the holding frame 703 is slid. , It is possible to suppress fraudulent activities.

Further, since the standing wall portions 711a to 711d are erected so as to surround the ROM 121 mounted on the second substrate 12B, they move in any direction along the base plate 801a when the ROM 121 is removed from the socket 700A. Since it becomes difficult to make it, it is possible to more preferably suppress cheating. In this embodiment, the vertical wall portions 711a to 711d are erected so as to surround the ROM 121 mounted on the second substrate 12B, but the present invention is not limited to this, and the second substrate 12B As long as it is erected on the side of the ROM 121 on the front surface 12f, it does not necessarily have to be a continuous wall portion so as to surround the periphery of the ROM 121. For example, only one wall portion is erected on the side of the ROM 121. Alternatively, a plurality of wall portions may be erected so as to surround the periphery of the ROM 121.

Further, the base plate 801a of the base member 801 is provided with a heat radiating hole 829, and the heat radiating hole 829 is formed at a position other than the position facing the socket 700A, so that the jig, the wire, etc. can be removed from the heat radiating hole 829. Since it is difficult to reach the socket 700A even if it is inserted, it is possible to prevent the ROM 121 from being easily removed. Further, it is possible to insert a foreign substance such as a wire through the heat radiation hole 829 to make it difficult to illegally modify the ROM 121.

Next, modifications 1 to 4 of the present invention will be described with reference to FIGS. 17 to 20. FIG. 17 is a cross-sectional view showing a main part of a substrate case as a modification 1 of the present invention. FIG. 18 is a cross-sectional view showing a main part of a substrate case as a modification 2 of the present invention. FIG. 19 is a cross-sectional view showing a main part of a substrate case as a modification 3 of the present invention. FIG. 20 is a cross-sectional view showing a main part of a substrate case as a modification 4 of the present invention. Regarding the substrate cases of the modified examples 1 to 4, only the configuration different from that of the above embodiment will be described, and the description of the configuration will be omitted as in the above embodiment.

As shown in FIG. 17, the substrate case 800C as the first modification has a front-rear distance distance from the front end of the standing wall portions 711a to 711d to the base plate 801a in a state where the second substrate 12B is housed in the substrate case 800D. L10 is configured to be arranged so as to be shorter than the front-rear dimension L13 of the holding frame 703 (L10 <L13).

In the above embodiment, since the separation dimension L10 is longer than the front-rear dimension L13, the holding frame 703 can be passed through the gap between the front ends of the standing wall portions 711a to 711d and the base plate 801a. However, by making the separation dimension L10 shorter than the front-rear dimension L13 in this way, even if the holding frame 703 is moved forward from the mounting portion 710F, the holding frame 703 is kept at the front end and the base of the standing wall portions 711a to 711d. It becomes difficult to pass through the gap with the plate 801a and take it out from the housing 701. That is, since the holding frame 703 cannot be removed from the housing 701, the holding frame 703 becomes an obstacle and the ROM 121 cannot be removed from the housing 701.

As shown in FIG. 18, the substrate case 800D as a modification 2 has a front-rear distance distance from the front end of the standing wall portions 711a to 711d to the base plate 801a in a state where the second substrate 12B is housed in the substrate case 800D. L10 is configured to be arranged so as to be longer than the plate thickness dimension L11 of the ROM 121 (L10> L11). In such a case, the ROM 121 can be moved forward from the mounting portion 710F and then moved in the direction along the second substrate 12B (up / down / left / right direction).

Even in such a case, for example, the first substrate 12A is arranged at a position near the upper side of the socket 700A, and the separation dimension L21 between the first substrate 12A and the base plate 801a in the front-rear direction is the plate of the ROM 121. Since the thickness is shorter than the thickness L11 (L21 <L11), even if the holding frame 703 is taken out from the housing 701, the ROM 121 is passed through the gap between the first substrate 12A and the base plate 801a to form the substrate case 800D. It becomes difficult to pull out from above.

Further, the rib 804a is arranged near the lower side of the socket 700A, and the distance distance L22 between the rib 804a and the base plate 801a in the front-rear direction is shorter than the plate thickness size L11 of the ROM 121 (L22). <L11), it is difficult to pass the ROM 121 through the gap between the front end of the vertical wall portions 711a to 711d and the rear end of the rib 804a and pull it out from below the substrate case 800D.

As shown in FIG. 19, the substrate case 800E as a modification 3 has a front-rear distance distance from the front end of the standing wall portions 711a to 711d to the base plate 801a in a state where the second substrate 12B is housed in the substrate case 800E. L10 is configured to be arranged so as to be longer than the plate thickness dimension L11 of the ROM 121 (L10> L11), but the step portion 814b'is located above the socket 700A on the base plate 801a. Since it is closer to the first substrate 12A side than the base plate 801a in front of the socket 700A, the distance distance L23 between the first substrate 12A and the base plate 801a in the front-rear direction is larger than the plate thickness dimension L11 of the ROM 121. Due to the short size (L23 <L11), it is difficult to pass the ROM 121 through the gap between the first substrate 12A and the base plate 801a and pull it out from above the substrate case 800E.

Further, a rib 815 projecting from the back surface of the base plate 801a is arranged at a position near the lower side of the socket 700A, and the separation dimension L24 between the rib 815 and the base plate 801a in the front-rear direction is the plate thickness dimension L11 of the ROM 121. Since the size is shorter than that (L24 <L11), it is difficult to allow the ROM 121 to pass through the gap between the front end of the vertical wall portions 711a to 711d and the rear end of the rib 815 and to be pulled out from below the substrate case 800E.

As shown in FIG. 20, the substrate case 800F as a modification 4 has a front-rear distance distance from the front end of the standing wall portions 711a to 711d to the base plate 801a in a state where the second substrate 12B is housed in the substrate case 800F. L10 is configured to be arranged so as to be longer than the plate thickness dimension L11 of the ROM 121 (L10> L11), but the first substrate 12A is located near the upper side of the socket 700A on the base plate 801a. Since there is an electronic component 850 mounted on the front surface of the ROM 121, the separation dimension L25 between the electronic component 850 and the base plate 801a in the front-rear direction is shorter than the plate thickness dimension L11 of the ROM 121 (L25 <L11). It is difficult to pass the ROM 121 through the gap between the electronic component 850 and the base plate 801a and pull it out from above the substrate case 800F.

Further, the boss 804 is arranged near the lower side of the socket 700A, and the distance between the boss 804 and the base plate 801a in the front-rear direction L26 is shorter than the plate thickness L11 of the ROM 121 (L26). <L11), it is difficult to pass the ROM 121 through the gap between the front ends of the standing wall portions 711a to 711d and the boss 804 and pull it out from below the substrate case 800F.

As shown in these modified examples 2 to 4, the separation dimension L10 from the front end of the standing wall portions 711a to 711d to the base plate 801a is longer than the front-rear dimension L13 of the holding frame 703 and the plate thickness dimension L11 of the ROM 121. The first substrate 12A, the boss 804, and the rib 804a as an obstructive portion that hinders the movement of the ROM 121 in the direction along the second substrate 12B at a position near the side of the socket 700A, even when arranged in such a manner. The presence of the step portion 814b', the rib 815, the electronic component 850, and the like can prevent the ROM 121 from being illegally removed.

It is preferable that these obstructing portions are arranged near the socket 700A, but the near position means that the distance dimension La from the socket 700A to the obstructing portion is the width dimension L12 of the ROM 121 (the obstructing portion is on the upper and lower sides). It is preferable that the dimension is shorter than the vertical dimension when it is on the side and the left and right dimension when it is on the left and right sides (La <L12). When the separation dimension La is approximately the same as the width dimension L12 or longer than the width dimension L12, the ROM 121 can be passed between the obstruction portion and the standing wall portions 711a to 711d, but there is an obstruction portion. As a result, the gap in the front-rear direction is narrowed, which makes it difficult to move the ROM 121, so that fraudulent activity can be suppressed.

Further, since the boss 804, the rib 804a, the step portion 814b'and the rib 815 as the obstructing portions are provided on the base member 801 side to which the second substrate 12B cannot be attached, when the ROM 121 is attached to or detached from the socket 700A. , These inhibitors are prevented from interfering with each other.

Then, the boss 804, the rib 804a, the step portion 814b'and the rib 815 as these obstructing portions are sockets 700A by rotating the cover member 802 with respect to the base member 801 as shown in FIGS. 8A and 8B. Since it is close to the socket 700A, it can be arranged closer to the socket 700A.

Further, as shown in FIGS. 8B and 8C, the boss 804 and the rib 804a slide the cover member 802 downward with respect to the base member 801 when the base member 801 and the cover member 802 are assembled. Because it is closer to the socket 700A, it can be arranged closer to the socket 700A.

Further, the socket 700A described in the above-described examples 1 to 3 has a standing wall portion 711a to 711d as a wearer-side obstructing portion that prevents the ROM 121 from moving along the base plate 801a in the second state. As a result, the movement of the ROM 121 along the base plate 801a is hindered, so that the removal of the ROM 121 from the socket 700A can be suitably suppressed.

Further, in the substrate cases 800, 800D, 800E, 800F, the first substrate 12A, the boss 804, the rib 804a, and the step portion as a case-side obstructing portion that hinders the ROM 121 from moving along the base plate 801a in the second state. Having the 814b', the rib 815, the electronic component 850, and the like hinders the movement of the ROM 121 along the base plate 801a, so that the removal of the ROM 121 from the socket 700A can be suitably suppressed.

Further, the second substrate 12B is housed in the substrate cases 800, 800D, 800E, 800F in a state of being attached to the cover member 802, and the case side obstructing portions (for example, the first substrate 12A, the boss 804, the rib 804a, and the step portion 814b). ', Ribs 815, electronic parts 850, etc.) are provided on the base member 801 so that when the ROM 121 is mounted on the second substrate 12B, the obstruction portion on the case side becomes an obstacle and workability is reduced. Can be prevented.

Further, as shown in FIGS. 8A and 8B, the boss 804, the rib 804a, the step portion 814b'and the rib 815 as the obstructing portions are formed by rotating the cover member 802 with respect to the base member 801 to form the socket 700A. When the ROM 121 is mounted on the second substrate 12B, it is possible to prevent the obstruction portion on the case side from becoming an obstacle and reducing the workability.

Further, since the boss 804 also serves as a substrate presser for pressing the second substrate 12B housed in the substrate cases 800, 800D, 800E, 800F, it is not necessary to provide an obstructing portion separately from the boss 804. The structure can be simplified.

Further, as the case-side obstruction portion, the first substrate 12A, the boss 804, the rib 804a, the step portion 814b', the rib 815, the electronic component 850, and the like are described, but they are arranged on the side of the socket 700A as described above. It is not limited to the above, and may be arranged at a position corresponding to the socket 700A on the base plate 801a. For example, when a protrusion is projected from the housing 701 at a position facing the opening of the housing 701 on the back surface of the base plate 801a and the holding frame 703 or ROM 121 is taken out from the housing 701, the housing 701 comes into contact with the holding frame 703 or ROM 121. An obstruction may be provided to regulate removal from.

Further, on the base plate 801a of the base member 801, the position of the case-side obstruction portion (for example, the boss 804 as the obstruction portion, the rib 804a, the step portion 814b'and the rib 815) can be specified from the outside of the substrate case 800. Since the marking portions 840 and 841 are provided as the marking portions, the positional relationship between the socket 700A and the case-side obstructing portion can be easily confirmed from the outside of the substrate case 800 at the time of manufacturing the substrate case 800 or the like. Can be done.

Further, the effect control board 12 is a second board as a second board arranged at a position farther from the base plate 801a than the first board 12A in a state of being housed in the first board 12A as the first board and the board case 800. It has a substrate 12B, and a socket 700A is provided on the second substrate 12B so as to face the base plate 801a, and the first substrate 12A prevents the ROM 121 from moving along the base plate 801a in the second state. By doing so, it is possible to prevent the ROM 121 from being removed from the socket 700A by moving it along the base plate 801a.

Further, in the above embodiment, the effect control board 12 is exemplified as the circuit board, but the present invention is not limited to this, and other controls such as the main board 11 and the payout control board 91 on which electronic components are mounted are not limited to this. A substrate may be applied.

Further, in the above-described embodiment, the ROM 121 and the character ROM 126 that store a program for effect control, fixed data, and the like are exemplified as electronic components, but the present invention is not limited to this, and the effect control CPU 120 and the game. Other electronic components related to control that give an advantage to the player, such as a ROM 101 or a CPU 103 that stores a control program or fixed data, may be applied. That is, in particular, electronic components related to control that give an advantage to the player, such as ROM 121 and ROM 101, are likely to be subject to fraud. Therefore, if the present invention is applied to such electronic components, fraudulent activities are suitably suppressed. It is preferable because it can be performed, but the present invention may be applied to an electronic component that is not related to control that gives an advantage to the player.

The advantage given to the player includes a game medium used for a game such as a pachinko ball, a game value (so-called credit) stored as a game medium owned by the player, and a privilege advantageous to the player. To do.

Here, the privilege that is advantageous to the player is, for example, the control that gives the player an advantage, for example, when the effect control CPU 120 has a plurality of types of jackpots having different numbers of rounds as the jackpot type. , Notifies that the number of rounds to be executed during the jackpot is announced, and that the jackpot game shifts to a high probability state after the jackpot ends during the jackpot game in which the jackpot is hit by a normal jackpot symbol that is not a probability fluctuation symbol. It is an advantageous state for the player, such as a promotion notification effect to be performed, and a latent notification effect suggesting that the state may be controlled to a high probability state in a state where the transition to the high probability state is not notified after the end of the big hit. Includes the right to perform a notification effect, etc.

Further, the game control microcomputer 100 has a specific game state (big hit, etc.) that is advantageous for the player who can acquire many game media, and a plurality of types of specific game states (which have different expected values of the game media that can be acquired). A high-probability gaming state (high-probability state) with a high probability of becoming the specific gaming state, or a high-base state (time saving state) in which the conditions for paying out prize balls are more likely to be satisfied than in a normal gaming state (such as a big hit with a different number of rounds). ), High probability and low base state (latent probability change state), special reach state (for example, super reach, etc.), the right to shift to a state in which the fluctuation pattern is a fluctuation pattern based on the jackpot fluctuation pattern, and the like.

Further, in the above embodiment, the effect control board 12 has a plurality of boards including the first board 12A and the second board 12B, but the present invention is not limited to this, and three or more boards are used. It may be configured including, or it may be configured by one substrate.
