  In recent pachinko machines, a wire or the like is inserted into a gap between the pachinko machines, and the inner frame is opened by unlocking the outer frame and the inner frame with the wire, and the ROM provided on the board of the main controller is installed. Instead of replacing the board case to protect the board of the main control device, the board case is illegally replaced with an unauthorized one. It ’s harder to tell if it ’s legitimate or if it was exchanged by fraud).

In order to solve the above problems, JP-A-9-239095 (Patent Document 1), JP-A-10-249025 (Patent Document 2), JP-A-11-004947 (Patent Document 3), In JP-A-11-137807 (Patent Document 4), JP-A-2000-325632 (Patent Document 5), etc., in order to make a board case for protecting a board, such as a main controller, unremovable from a gaming machine. A technique is disclosed in which a lock mechanism is provided, and the lock mechanism cannot be unlocked unless it is a predetermined key. Japanese Patent Laid-Open No. 9-239095 (Patent Document 1) discloses a configuration in which a variable lock device capable of changing a key for unlocking is provided.
In the current pachinko machine, an inner frame and a front frame are used by using a variable cylinder lock as described in JP-A-3-187478 (Patent Document 6) and JP-A-4-118478 (Patent Document 7). Is fixed (locked).

  By adopting the configuration disclosed in Patent Documents 1 to 5, fraud such as changing to an unauthorized one for each board case protecting the board of the main controller can be avoided, but the main controller fails. When removing the main controller from the pachinko machine for inspection, as described above, first unlock the inner frame with a dedicated key, open the inner frame, Since the lock mechanism that fixes the board case that protects the board of the main controller is released with a key that is different from the key for unlocking the inner frame, it takes time and requires multiple different keys. The problem of becoming.

In order to solve the above-mentioned problem, a gaming machine according to claim 1, an outer frame forming a vertically long fixed outer holding frame, an inner frame that is provided so as to be openable and closable with respect to the outer frame, and to which a game board is attached, A front frame that is openable and closable with respect to the inner frame; a frame opening restriction device that restricts the opening operation of the inner frame and / or the front frame; and the inner frame and / or the front frame that is provided by the frame opening restriction device. In a gaming machine comprising a frame locking device for releasing the restriction of the opening operation of the frame, a board of a control device for controlling the gaming machine and a board case for protecting the board,

The substrate case restriction device releases the restriction on removing the substrate case when the restriction on the opening operation of the inner frame by the frame opening restriction device is released along with the unlocking of the frame locking device. A gaming machine configured such that when the restriction of the opening operation of the inner frame by the frame opening restriction device is released without unlocking the lock device, the restriction of removal of the substrate case is not released. It is.

The gaming machines are roughly divided into three frames, an outer frame, an inner frame, and a front frame, and game parts are attached to the respective frames. The front frame is also called a glass frame because a transparent member (glass or resin) provided on the front surface of the gaming machine is attached.
By providing hinges on the left and upper sides of the outer frame and the inner frame, and also providing hinges on the left and upper sides of the inner frame and the front frame, the inner frame can be opened and closed with respect to the outer frame, and the front frame is It can be opened and closed.
If the inner frame is released, the front frame attached to the inner frame naturally moves together with the inner frame, but the front frame is not released from the inner frame.
A game board on which nails and winning holes are arranged and the launched game balls roll is attached to the inner frame, but the game board may be directly attached to the inner frame, or the game board may be attached to the inner frame. You may make it the structure which attaches a member and attaches a game board to this game board attachment member. In addition, a configuration may be adopted in which a ball tank, a tank rail, a payout device, etc. for paying out a prize ball to be paid out when a game ball wins a winning opening is attached to the mechanism plate, and the mechanism plate is attached to be openable and closable. You may make it the structure which attaches a ball tank, a tank rail, and a payout apparatus to an inner frame directly.

In addition, the gaming machine has a main control device that controls the entire gaming machine, a dispensing control device that controls the dispensing of gaming balls, a power supply board (device) that controls the power supply of the gaming machine, a firing control device that controls the launching of gaming balls, Various control devices are provided such as an effect symbol control device that controls the effect symbol display device, a lamp control device that controls a light emitting member provided in the gaming machine, and a sound control device that controls sounds generated from the gaming machine. .

In this configuration, the frame opening restriction device restricts both the inner frame and the front frame, and the frame opening restriction device and the frame lock device are integrally formed, but there are two frame opening restriction devices. The inner frame and the front frame may be configured to be restricted by different frame opening restriction devices, or the frame opening restriction device and the frame lock device may be provided separately.
The frame opening restriction device of this configuration is provided with a plurality of movable engagement hooks on each of the front surface and the rear surface, and the frame opening restriction device provided with the engagement hooks is attached to the inner frame. On the other hand, an engagement metal fitting that engages with the engagement hook is provided on the front frame and the outer frame, and the opening operation of the inner frame and the outer frame is restricted by engaging the engagement hook and the engagement metal (on the front side). The engagement hook provided is engaged with the engagement fitting provided on the front frame, and the engagement hook provided on the rear surface is engaged with the engagement fitting provided on the outer frame.

The board case that restricts removal from the gaming machine by the board case regulating device stores the board of the control device that is likely to be cheated. That is, removal of the board case protecting the board of the main control device or the payout control device from the gaming machine is regulated by the board case regulating device.
The substrate case that protects the substrates of the main control device and the payout control device includes a substrate base and a substrate cover, and is provided with a plurality of screw holding portions for assembling the substrate base and the substrate cover. When it is opened, for example, it is configured to be screwed using a one-way screw that can only be rotated.

The substrate case restriction device releases the restriction on the removal of the substrate case when the restriction on the opening operation of the inner frame by the frame opening restriction device is released along with the unlocking of the frame lock device. When the restriction of the opening operation of the inner frame by the frame opening restriction device is released without unlocking the device, it is configured not to release the restriction of removal of the substrate case. Even if the restriction of the frame opening restriction device is forcibly used and the inner frame is opened, the restriction of the substrate case restriction device is not released, and the restriction of the frame restriction device is released by unlocking the frame locking device. In other words, the restriction of the substrate case restriction device is released. In other words, in this configuration, if the frame locking device is unlocked, the restriction of the frame opening restriction device is surely released, but the frame locking device is not unlocked even if the restriction of the frame opening restriction device is released. .
It should be noted that the restriction of the substrate case restriction device is released only when the frame lock device is unlocked, that is, a configuration in which a dedicated key is not provided to release the restriction of the substrate case restriction device. Is preferred.
In addition, the method of restricting the removal of the substrate case by the substrate case restricting device is to provide a gate-shaped enclosure on the back side (substrate base portion) of the substrate case, and to insert the tip of the solenoid into the enclosed portion, so that the solenoid is excited. Then, if the distal end portion does not shrink, a structure in which the gate case and the solenoid are in contact with each other and the board case cannot be removed is conceivable. However, the present invention is not limited to this configuration, and a configuration may be employed in which a movable guide member is provided in front of the substrate case, and the movement of the guide member is fixed (restricted) by a solenoid.
As a method of releasing the restriction on the removal of the substrate case by the substrate case restriction device when the restriction on the opening operation of the inner frame by the frame opening restriction device is released along with the unlocking of the frame lock device. A configuration is conceivable in which power is supplied to the substrate case regulating device (solenoid, etc.) as the frame lock device is unlocked.
Note that power supplied to the board case regulating device may be supplied from the outside of the gaming machine or may be supplied from a power board provided in the gaming machine.

In order to solve the above-mentioned problem, the gaming machine according to claim 2, wherein the frame lock device is a variable lock that can freely change a type of a key for unlocking the frame lock device by a setting key,
The restriction on the removal of the substrate case by the substrate case restriction device is released only when the restriction on the opening operation of the inner frame by the frame opening restriction device is released along with the unlocking of the frame locking device by the setting key. 2. The gaming machine according to claim 1, wherein the board case is removable from the gaming machine.

The frame lock device is a variable lock that can freely change the type of key for unlocking the frame lock device (specifically, a variable cylinder lock called OMLOCK manufactured by OMRON Corporation is used) To do.) By using such variable locks, pachinko manufacturers will ship pachinko machines equipped with variable locks of the same configuration to amusement stores. It will be compatible with all manufacturers' pachinko machines. Moreover, it becomes possible to easily change the keys of all the pachinko machines provided in the pachinko parlor.
According to the second aspect of the present invention, even if the frame locking device is unlocked with the key set to unlock the frame locking device, the restriction of the substrate case restriction device is not released, and the frame locking device is unlocked. Only when the frame locking device is unlocked by a setting key for setting a key to do so, the restriction of the board case restriction device is released, and the board case can be removed from the gaming machine. Even if the frame lock device is currently set to be unlocked by any key, the frame lock device is unlocked by using the set key. Specifically, a configuration is conceivable in which power is supplied to the substrate case regulating device only when the frame lock device is unlocked using the setting key.

According to the first aspect of the present invention, for example, the substrate case for protecting the substrate such as the main control device cannot be removed from the pachinko gaming machine even if the inner frame is opened using a wire or the like. Injustices such as changing each case can be prevented. Note that the substrate case can be removed from the pachinko gaming machine by destroying the substrate case regulating device or a part of the substrate case. However, since traces always remain, it is easy to determine whether fraud has been performed.
Also, it is not fraudulent, and when removing the board case that protects the board of the main controller, etc. from the pachinko machine for some reason (failure, inspection, etc.), the board case can be easily removed, and multiple keys are not required. It does not take time and effort.

  According to the second aspect of the present invention, the restriction of the board case restriction device is unlocked only when the frame lock device is unlocked by the setting key for changing the type of the key for unlocking the frame lock device. Since the board case cannot be removed from the gaming machine, it is only necessary to store strictly the setting keys that are not normally used, so make a fake key to unlock the set frame lock device, Even when unlocked, it is not possible to perform a fraud such as replacing the board (including the board case) from an authorized one to an unauthorized one.

The voice / lamp integrated control device 83 and the production symbol control device 82 are capable of bidirectional communication.
The production symbol control device 82 is based on the data and commands received from the voice / lamp integrated control device 83 (both those transmitted from the main control device 80 and those generated by the voice / lamp integrated control device 83). Then, the effect symbol display device 6 is controlled to display an effect image such as a pseudo symbol on the screen 6a.

Next, each process performed by the main controller 80 as a main routine will be described with reference to FIG.
The flowchart shown in FIG. 5 represents a main process executed by the microcomputer of the main controller 80, and is a process periodically executed by a hardware interrupt every about 2 ms. In the present embodiment, each process from S10 to S21 is a process that is executed only once in the interrupt process, and is referred to as “main process”, and is repeated as long as time permits within the remaining time after executing this main process. The process of S22 to be executed is referred to as “residual process”.

  When a hardware interrupt is executed by the microcomputer, it is first determined whether or not the interrupt is a normal interrupt (S10). This determination process is performed by determining whether or not the value of a predetermined area of the RAM as a memory is a predetermined value. When the process executed by the microcomputer shifts to this process, the normal process is executed. It is for judging whether it is okay. If the interrupt is not normal, microcomputer runaway due to noise or the like may be considered when power is turned on. However, microcomputer runaway may be considered to be almost impossible due to recent technological improvements, and is usually when power is turned on. When the power is turned on, the value of the predetermined area of the RAM is different from the predetermined value.

  If it is determined that the interrupt is not normal (S10: NO), the initial value is written to the work area of the memory, such as writing a predetermined value in the predetermined area of the memory, and using a special symbol and a normal symbol as an initial symbol, that is, Initial settings are made (S11), and the process proceeds to a residual process.

  If a positive determination is made that the interrupt is normal, an initial value random number update process is first executed (S12). This process is an increment process that increments the initial random number value by 1 each time this process is executed. The initial random number value before this process is incremented by +1, but the random number value before this process is executed is the maximum. When the value is “349”, it returns to the initial value “0” in the next processing, and 350 integers from “0” to “349” are repeatedly generated in ascending order.

The jackpot determination random number update process (S13) subsequent to S12 is an increment process that increments by one each time the process is executed, similar to the initial value random number update process. When the maximum value is "349", the next process starts with the next process. Then, 350 integers from “0” to “349” are repeatedly generated in ascending order.
When the jackpot determining random number is one week (one round), the initial value random number at that time is set as the initial value of the jackpot determining random number, and the jackpot determining random number is incremented by 1 from the initial value. . Then, when the big hit determining random number is again one week (one round), the operation of setting the initial value random number at that time to the initial value of the big hit determining random number is performed. That is, this series of operations is repeated.

  The jackpot symbol determination random number update process (S14) is configured as a counter that repeatedly creates ten integers “0” to “9”, and is incremented by +1 for each process and is the initial value “0”. Return to.

The hit determination random number update process (S15) following S14 is configured as a counter that repeatedly generates six integers “0” to “5”, and is incremented by 1 every time this process exceeds the maximum value. Return to a certain “0”. The number of values to be won is 3 in both the normal probability state and the high probability state, and the values are “0”, “3”, and “5”.
This winning determination random number update process is used for lottery of normal symbols, and other initial value random numbers, big hit determination random numbers, big hit symbol determination random numbers, reach determination random numbers, fluctuation pattern determination random numbers are lottery of special symbols Used for.

  The reach determination random number update process (S16) is configured as a counter that repeatedly generates 229 integers from “0” to “228”, and is incremented by +1 for each process and is the initial value “0”. Return to. In the normal probability state, the number of values won when the variable time shortening function is not activated is 21, and the values are “0” to “20”. The number is 5, the values are “0” to “4”, the number of values to be won in the high probability state is 6, and the values are “0” to “5”.

  The variation pattern determination random number update process (S17) is configured as a counter that repeatedly creates 1021 integers from “0” to “1020”, and is incremented by 1 for each process and is the initial value when the maximum value is exceeded. Return to "0".

In the subsequent winning confirmation process (S18), confirmation of winning of the first start port 11 and second start port 12 and input processing of each switch provided in the pachinko machine 50 and connected to the main controller 80 are executed.
In this embodiment, when a game ball wins the first start port 11 and the second start port 12, a plurality of random numbers such as a big hit determination random number, a big hit symbol determination random number, a variation pattern determination random number, a reach determination random number, etc. are acquired. However, the number that can be reserved is limited to four, and when the reserved memory is full, even if the game ball wins the first start port 11 or the second start port 12, the prize ball is paid out. The plurality of random numbers are simply not stored on hold.

  Subsequently, a success / failure determination process (S19) as condition establishment determination means for determining whether or not a big hit is made. This success / failure determination process will be described later. When this success / failure determination process (S19) ends, each output process (S20) such as an image output process is subsequently executed.

  In each output process (S20), as the game progresses, the main control device 80 sends to the effect symbol control device 82, the payout control device 81, the launch control device 84, the voice / lamp integrated control device 83, the big prize opening solenoid 14b, and the like. Each output process is executed. That is, when it is detected in the winning confirmation process (S18) that there is a winning game ball in each winning slot on the game board 10, the winning ball data is output to the payout control device 81 so as to pay out the gaming ball as a winning ball. The process of outputting the sound data corresponding to the gaming state to the voice / lamp integrated control device 83 is an error signal to the effect symbol control device 82 to notify that there is an error when the pachinko machine 50 is abnormal. Each of the processes for outputting is executed.

  The subsequent fraud monitoring process (S21) is a process for monitoring whether or not fraud is performed on the normal winning opening (left sleeve winning opening 31, left falling winning opening 32, right sleeve winning opening 33, right falling winning opening 34). This is a process for judging whether or not the number of game balls entering the winning opening in a predetermined time is greater than a predetermined number, and if so, it is judged to be illegal and a notification to that effect is made. . That is, the abnormality determination means is provided in the main controller 80.

  The remaining process subsequent to this process is composed of the initial value random number update process (S22), which is exactly the same process as S12 described above. This process forms an infinite loop and is repeated as long as time is allowed until the next interrupt is executed. The time required to execute the above-described processing from S10 to S21 differs for each interrupt depending on whether or not to execute the jackpot processing, the difference in the display mode of special symbols, and the like. As a result, the number of times the remaining process is executed is different for each interrupt, and the initial value random number updated (added) value is not uniform by executing the interrupt process shown in FIG. 5 once. As a result, there is no possibility that the initial value random number is synchronized with the jackpot determination random number. In the present embodiment, the big hit determination random number is updated according to the value of the initial random number, so there is no possibility of synchronization. The hit determination random number update process (S15) described above may also be executed in the remaining process.

In the start winning confirmation process shown in FIG. 6, the main control device 80 plays a game ball on the first start port 11 or the second start port 12 based on the detection signal of the first start port switch 11a or the second start port switch 12a. It is determined whether or not a ball has entered (S30).
If it is affirmative, read the jackpot determination random number, the jackpot symbol determination random number, the reach determination random number, the variation pattern determination random number, etc. from the corresponding counters to see if the special symbol hold memory is full (four in this embodiment). It is determined whether or not (S31).
If the reserved memory is not full (S31: NO), the above random numbers are stored as special symbol reserved memory, and the number of lighting of the special symbol reserved memory display device 10 is increased by 1 (S32). If there are already four reserved memories (S31: YES), no reserved memories are stored, and the number of lighting of the special symbol reserved storage display device 10 is not increased.
In addition, the increase / decrease in the number of reserved symbols of the special symbol is transmitted to the effect symbol control device 82 via the voice / lamp integrated control device 83, and the special symbol reservation memory display device 10 displays the screen 6 a of the effect symbol display device 6. The same number of pseudo-hold displays as the number of lights.

In the success / failure determination process shown in FIG. 7, main controller 80 determines whether or not the condition device is operating based on the jackpot flag (S <b> 40).
If the determination in S40 is negative, the special symbol is not changing (S41: NO), and the confirmed symbol is not being displayed (S42: NO), whether or not there is a special symbol hold memory (the hold memory in S32 above). Is determined (S43).
If there is this reserved memory (S43: YES), the oldest special symbol reserved memory is read (the special symbol reserved memory is deleted from the reserved memory), and the probability variation flag is set (high probability state) It is determined whether or not (S44).
If the determination is affirmative (S44: YES), the read jackpot determination random number is checked against the hit value recorded in the probability variation table (S46). If the determination is negative, the read jackpot determination random number is stored in the normal table. It collates with the recorded hit value (S45).
In this embodiment, as described above, the player wins with a probability of 1/350 in the normal probability state and wins with the probability of 1/35 in the high probability game state.

If it is a big hit in the determination of S45 or S46 (S47: YES), the big hit symbol is determined by the big hit symbol determination random number (S48), and the variation pattern is determined by the variation pattern determination random number (S49).
On the other hand, if it is off (S47: NO), the variation pattern is determined based on the reach determination random number and the variation pattern determination random number (S50). In the case of the present embodiment, the display of the special symbol in the case of losing is only one type of “-”, so the losing symbol does not need to be determined.

Subsequent to S49 or S50, data indicating the lottery results described above, specifically, data indicating any one of normal jackpots, probability variation jackpots, out of reach (with out of reach but with reach display), or out of reach without display of reach A variation start command (display control command) including variation pattern data for designating the variation time is output to the voice / lamp integrated control device 83, and the special symbol display device 9 is controlled to start the variation display of the special symbol. (S51).
Therefore, based on the fluctuation start command, the voice / lamp integrated control device 83 can determine the jackpot symbol or the off symbol (hereinafter collectively referred to as a fixed symbol), the presence / absence of reach, and the variation time.
The voice / lamp integrated control device 83 that has received the fluctuation start command performs voice and lamp production control in response to the special symbol fluctuation display, and also sends a fluctuation start command to the production symbol control device 82.

If the special symbol is changing (S41: YES), main controller 80 determines whether the symbol change time (based on the change pattern of S49 or S50) has elapsed as shown in FIG. 8A. (S52).
If the determination is affirmative, a symbol stop command is output to the voice / lamp integrated control device 83, and the special symbol display device 9 is controlled to display the final symbol (S53).
Receiving the symbol stop command, the voice / lamp integrated control device 83 ends the voice and lamp presentation in response to the special symbol variation display, and sends a symbol stop command to the presentation symbol control device 82.

If the special symbol that has been confirmed and displayed is a jackpot (S54: YES), main controller 80 performs a confirmed symbol display setting process (S55), and sets a jackpot flag by a conditional device operation start process (S56). set.
Subsequently, it is determined whether or not the probability variation flag is set (S57). If the determination is affirmative, the probability variation flag is cleared (S58). If the determination is negative (S57: NO), it is determined whether or not the time reduction flag is set (time reduction state) (S59), and if the determination is affirmative, the time reduction flag is cleared (S60).

When the special symbol that has been confirmed and displayed is not a big hit (that is, missed) (S54: NO), a confirmed symbol display setting process (S61) is performed to determine whether or not the release extension flag is set (S62). . Note that the release extension flag is set during the high probability state and the time reduction state. If the release extension flag is set, the stored release extension number count is decremented by -1 (S63). If the count value becomes 0 (S64: YES), each flag is ended (S65).
In the process of S65, if the current state is a high probability state, the probability variation flag, the time reduction flag, and the release extension flag are ended, and if the current state is a time reduction state, the time reduction flag and the release extension flag are ended. If a negative determination is made in S62, S64, the process returns.

  If the confirmed symbol is being displayed in S42 (S42: YES), as shown in FIG. 8B, whether or not the confirmed symbol display time set in the confirmed symbol display setting (S55 or S61) has elapsed. If it is judged (S66) and has elapsed (S66: YES), the special symbol display device 9 is controlled by the final symbol display end processing (S67) to end the final display of the special symbol, and the voice / lamp integrated control is performed. An instruction is given to the production symbol control device 82 via the device 83, and the fixed display of the pseudo symbol is ended.

In the special game process shown in FIG. 9, the main control device 80 determines whether or not the condition device is operating based on the jackpot flag (S70).
If the condition device is in operation (S70: YES), it is determined whether or not the special winning opening 14 is open (S71).
The jackpot symbol is not being opened (S71: NO), not being a jackpot start effect (S72: NO), not being an interval (S73: NO), and not being a jackpot end effect (S74: NO) Then, the state of winning the jackpot is stored (S75), and a jackpot start command is transmitted to the voice / lamp integrated control device 83 by the jackpot start effect process (S76), and the big prize opening 14 is opened.

  The voice / lamp integrated control device 83 starts a jackpot voice and lamp production, and sends a jackpot start command to the production symbol control device 82. Upon receiving the jackpot command, the effect symbol control device 82 controls the effect symbol display device 6 to display a jackpot start effect (so-called fanfare screen). The big winning opening 14 is opened after the jackpot start effect.

If an affirmative determination is made in S72, S73, or S74, the process returns. If an affirmative determination is made in S71, it is determined based on the detection signal of the count switch 14a whether or not there are 10 winning balls for the special winning opening 14 (S77). It is determined whether or not (S78). If a negative determination is made in S78, the process returns. If a positive determination is made in S77 or S78, the special winning opening 14 is closed (S79).
Subsequently, it is determined whether or not it is the final round (S80). If the determination is negative, an interval command is transmitted to the voice / lamp integrated control device 83 through the jackpot interval process (S81), and the voice / lamp integrated control device 83 receives an interval. Waiting for the screen display of the effect symbol display device 6 to be changed under the control of the effect symbol control device 82 that has received the command, the special winning opening 14 is opened.

If the affirmative determination is made in S80, the jackpot operation is not continued, so the jackpot end effect process (S82) is executed, and then the condition device is stopped by the condition device stop process (S83) (the jackpot flag is cleared).
Then, if the jackpot symbol that has been determined and displayed on the special symbol display device 9 in S55 and stored in S75 is a probability variation symbol (S84: YES), a probability variation flag / time reduction flag operation process (S85) is performed, and a probability variation flag and a time reduction flag are displayed. The open extension flag is set, and the open extension counter value is set to 10,000.
When the symbol is not a probable variable (S84: NO), the hour / short flag and the release / extension flag are set by the hour / short flag operation process (S86), and the value of the release / extension counter is set to a value corresponding to the big hit symbol (in this embodiment, Any one of 20, 40, 60, 80, and 100). To do.
After the processing of S85 or S86, a jackpot end command is transmitted to the voice / lamp integrated control device 83 (S87).

As described above, the front frame regulating slide member 46 includes the upper claw portion 46a, the middle claw portion 46b, and the lower claw portion 46c, and the three claw portions also slide downward simultaneously.
On the other hand, the front frame 52 is provided with a front frame fixing member 38 as shown in FIG. 13, and the outer frame 51 is provided with two inner frame fixing members 37 as described above. In FIG. 13, only one front frame stopper member 38 is provided on the upper portion of the front frame 52, but the front frame 52 is provided with a total of three front frame stopper members 38. ing.

13 is an enlarged view of the upper side of the slide lock 60, and the diagram on the left side of FIG. 13 shows a state in which the opening operation of the front frame 52 and the inner frame 70 is restricted by the slide lock 60, and the middle of FIG. This figure shows a state in which the opening operation of the inner frame 70 is restricted by the slide lock 60, but the restriction of the opening operation of the front frame 52 is released. The figure on the right side of FIG. 60 shows a state in which the opening operation of the front frame 52 is regulated, but the regulation of the opening operation of the inner frame 70 is unlocked.
As described above, by inserting the key set in the cylinder lock 39 and turning the key clockwise, the upper slide member 44 and the lower slide member 45 connected to the central slide member 43 are moved. Slide up. As the upper slide member 44 slides upward, the inner frame regulating upper claw member 41 that is rotatably attached rotates upward. Similarly, when the lower slide member 45 slides upward, the inner frame regulating lower claw member 42 that is rotatably attached rotates upward. As shown in the drawing on the right side of FIG. 13, the inner frame restriction upper claw member 41 is turned upward so that the inner frame restriction upper claw member 41 is disengaged from the inner frame stopper member 37 provided on the outer frame 51. become. Although not shown in FIG. 13, the inner frame restriction lower claw member 42 is provided on the outer frame 51 in the same manner as the inner frame restriction lower claw member 42 rotates upward. It will come off from the member 37. In this way, the inner frame 70 can be opened.
On the other hand, when the key set in the cylinder lock 39 is inserted and the key is turned counterclockwise, the front frame regulating slide member 46 (upper claw portion 46a, middle claw portion 46b, lower claw portion 46c) slides downward. To do. As shown in the middle diagram of FIG. 13, the upper claw portion 46 a slides downward, so that the upper claw portion 46 a is detached from the front frame stopper member 38 provided on the front frame 52. Although not shown in FIG. 13, the middle claw portion 46 b and the lower claw portion 46 c are similarly slid downward so that the middle claw portion 46 b and the lower claw portion 46 c are provided on the front frame 52. The front frame stopper member 38 will come off. In this way, the front frame 52 can be opened.

  As shown in FIGS. 11 and 12, an upper slide member return spring 47, a lower slide member return spring 48, and a front frame regulating slide member return spring 49 are attached to the slider lock body member 40. An upper slide member 44 is attached to the other of the slide member return springs 47, a lower slide member 45 is attached to the other of the lower slide member return springs 48, and a front frame restriction is attached to the other of the front frame restriction slide member return springs 49. The slide member 46 is attached, and the upper slide member 44 and the lower slide member 45 are pulled so as not to slide upward, and the front frame regulating slide member 46 is pulled so as not to slide downward. It has become. That is, when the upper slide member 44 and the lower slide member 45 are slid upward, when the hand is released from the key, the upper slide member 44 and the lower slide member 45 slide downward (return to the initial position), and the front If the hand is released from the key while the frame regulating slide member 46 is sliding downward, the front frame regulating slide member 46 slides upward (returns to the initial position). When the hand is released from the key (from a state where it is rotated in either direction), the key also returns to the initial position (rotation angle).

In the present embodiment, as described above, by inserting a predetermined key into the cylinder lock 39 and rotating the key, some parts of the slide lock 60 slide, and the inner frame 70 or the front frame 52 can be opened. For example, without using a key, the inner frame restriction upper claw member 41, the upper slide member 44, the center slide member 44, the lower slide member 45, and the inner frame restriction lower claw Even if the member 42 and the front frame regulating slide member 46 are moved, the cylinder lock 39 is configured not to change. That is, power is transmitted from the cylinder lock 39 to the slide lock 60, but power is not transmitted from the slide lock 60 to the cylinder lock 39.
In this embodiment, when the inner frame 70 is opened, the front frame 52 attached to the inner frame 70 also moves simultaneously. However, the front frame 52 is not opened with respect to the inner frame 70. However, the present invention is not limited to this configuration, and if the inner frame 70 is opened, the front frame 52 may be automatically opened.

FIG. 14 is a rear view of the game board 10, and as described above, the game board 10 is provided with the main control device 80, the production symbol control device 82, and the voice / lamp integrated control device 83.

Enters the fixing member 95 (inside the gate), and the substrate case fixing solenoid 97 is energized as shown in the lower diagram of FIG. 17 (substrate case fixing). When the tip of the solenoid 97 is contracted), the tip of the board case fixing solenoid 97 is detached from the fixing member 95.
That is, when the substrate case fixing solenoid 97 is demagnetized, the fixing member 95 is caught by the substrate case fixing solenoid 97 and the substrate case 90 cannot move upward. When the substrate case fixing solenoid 97 is excited, The fixing member 95 can move the substrate case 90 upward without interfering with the substrate case fixing solenoid 97.
That is, the substrate case fixing solenoid 97 corresponds to the substrate case regulating device.
However, the substrate case regulating device is not limited to the solenoid as described above, and may be a rotary solenoid or a motor.
Further, the shape of the fixing member 95 is not limited to the gate shape.
However, as described in the present embodiment, a configuration in which the substrate case 90 is fixed on the lower side (lower side of the substrate) of the substrate case 90 is desirable.
If it is configured to be fixed on the upper side of the substrate case 90, the electronic component provided on the substrate may be hidden by a fixing member or the like, but it is configured to be fixed on the lower side of the substrate case 90 as in this embodiment. Then, the electronic component provided on the substrate can be visually checked, and it can be easily confirmed whether or not the electronic component has been replaced with an illegal electronic component.

FIG. 18 is a diagram illustrating the flow of power of the pachinko machine 50.
As shown in FIG. 18, in the present embodiment, a substrate case removal control device 98 for controlling power supply to the substrate case fixing solenoid 97 is provided.
The substrate case removal control device 98 is provided on the inner frame 70 in this embodiment.
As shown in FIG. 18, in this embodiment, power (AC24V) supplied from the outside of the pachinko machine 50 is input to the power supply board 85, and the power supply board 85 generates the supplied power and supplies it to each control device. . As shown in FIG. 18, in this embodiment, power is supplied to the launch control device 84 from the payout control device 81. The sub-control devices described in FIG. 18 are the production symbol control device 82 and the voice / lamp integrated control device 83.
A signal from the cylinder lock 39 can be input to the substrate case removal control device 98, and the substrate case removal control device 98 controls power supply to the substrate case fixing solenoid 97 based on the signal. .
In this embodiment, when a signal indicating that the inner frame 70 has been released from the cylinder lock 39 (a signal indicating that the cylinder lock 39 has been unlocked) is input to the substrate case removal control device 98, the substrate case removal is performed. The control device 98 supplies power to the board case fixing solenoid 97. The substrate case fixing solenoid 97 to which the power is supplied is excited (the tip of the substrate case fixing solenoid 97 is retracted), and the fixing member 95 provided on the substrate case 90 does not contact the substrate case fixing solenoid 97, and the substrate case 90 can be removed from the main body of the gaming machine. That is, in normal times (when the cylinder lock 39 is not unlocked), the board fixing solenoid 97 is demagnetized.
In the present embodiment, as described above, the cylinder lock 39 is not unlocked by opening the inner lock 70 by sliding the slide lock 60 by unlocking the cylinder lock 39 using a predetermined key. For example, when a wire or the like is inserted into the gaming machine and the slide lock 60 is slid by the wire to open the inner frame 70, the cylinder lock 39 is not changed. That is, when the inner lock 70 is opened by sliding the slide lock 60 without unlocking the cylinder lock 39 in this way, the inner frame 70 is released from the cylinder lock 39 to the board case removal control device 98. Is not input, power is not supplied to the board case fixing solenoid 97, and the board case 90 cannot be removed from the gaming machine body.
Further, in the present embodiment, even when the slide lock 60 is slid by unlocking the cylinder lock 39 using a predetermined key and the front frame 52 is opened, the board case removal control device 98 from the cylinder lock 39. No signal is input and the substrate case 90 cannot be removed from the gaming machine body.
That is, in this embodiment, the substrate case 90 can be removed from the gaming machine main body only when the inner frame 70 is opened using a predetermined key (when the inner frame 70 is opened by unlocking the cylinder lock 39). It is the composition.

In this embodiment, in order to further prevent fraud, a key is inserted into the cylinder lock 39, the key is rotated clockwise, and while the key is maintained in the rotated position, the cylinder lock 39 A signal is continuously output to the substrate case removal control device 98, and the substrate case removal control device 98 supplies power to the substrate case fixing solenoid 97 only while receiving a signal from the cylinder lock 39. It has become.
That is, when the predetermined key is released from the hand, the inserted key returns to the predetermined position, the signal output from the cylinder lock 39 to the board case removal control device 98 is stopped, and the signal to the board case fixing solenoid 97 is stopped. Power supply is also stopped.
That is, in this embodiment, when removing the substrate case 90 from the gaming machine main body, a key is inserted into the cylinder lock 39, and the substrate case 90 is removed while the key is rotated clockwise.
However, the present invention is not limited to this configuration, and once a signal is input from the cylinder lock 39 to the substrate case removal control device 98, the substrate case removal control device 98 is in the middle of receiving a signal from the cylinder lock 39. Even if the operation stops, power may be supplied to the substrate case fixing solenoid 97 for a predetermined time. Furthermore, a detecting means for detecting the open / closed state of the inner frame 70 is provided, and when the power is supplied to the substrate case fixing solenoid 97 (that is, within a predetermined time), the detecting means detects that the inner frame 70 is closed. The power supply to the board case fixing solenoid 97 may be shut off before a predetermined time elapses.

In this embodiment, power is supplied from the power supply board 85 to the board case removal control device 98, and power is supplied from the board case removal control device 98 to the board case fixing solenoid 97. The power supply board 85 may be configured to supply power to the board case fixing solenoid 97 via the cylinder lock 39 without providing the removal control device 98. That is, when the key inserted into the cylinder lock 39 comes to a predetermined position, the line connecting the power supply substrate 85 and the substrate case fixing solenoid 97 is made conductive.
Further, power is not supplied from the power supply board 85 to the board case removal control device 98, but power is supplied from the outside of the gaming machine to the board case removal control device 98, and the board case removal control device 98 supplies the power to the board case removal control device 98. The generated power may be generated, and the generated power may be supplied to the substrate case fixing solenoid 97.

In the present embodiment, as the frame lock device, a variable lock that can be freely changed by a setting key is used as a key type for unlocking the frame lock device. Due to the opening of the inner frame 70 (because the cylinder lock 39 is unlocked), the board case 90 is configured to be removable from the gaming machine body (game board 10). With the set key, the inner frame 70 and the front frame 52 can be opened (the slide lock 60 can be slid (the restriction of the frame opening restriction device can be released)), but the board case 90 is attached to the gaming machine main body ( Only when the inner frame 70 is opened by the setting key (with the setting key), the configuration cannot be removed from the game board 10) (the configuration in which the restriction on the removal of the board case 90 by the board case regulating device is not released). Tablets 39 when unlocking only), the board case 90 may be configured detachable from the gaming machine main body (game board 10) (configuration in which regulation of removal of the substrate case 90 by board case limiting device is released).
With the key set in this way, the board case 90 cannot be removed from the gaming machine, and the board case 90 can be detached from the gaming machine only with the setting key, so that it is not normally used. Since it is only necessary to store only the key strictly, even if the fake key for unlocking the set frame lock device is made and the frame lock device is unlocked, the board (including the substrate case 90) is properly It is possible to prevent fraud such as replacing a thing with an unauthorized one.
As a specific method, a signal is input from the cylinder lock 39 to the substrate case removal control device 98 only when the inner lock 70 can be opened by unlocking the cylinder lock 39 with the setting key, and the cylinder lock 39 The board case removal control device 98 that receives the signal from the power supply supplies power to the board case fixing solenoid 97 (excites the board case fixing solenoid 97). When the cylinder lock 39 is unlocked with the set key, the signal from the cylinder lock 39 is not output.
Further, even when the cylinder lock 39 is unlocked by the setting key and only the front frame 52 can be opened, no signal is output from the cylinder lock 39 to the board removal control device 98, and the board case 90 can be removed from the gaming machine. A configuration that does not exist is preferable.
