Locking rod 22 is fixed. The through holes 21a to 21c and 22a to 22c are formed in a vertically long shape along the vertical direction (longitudinal direction of the middle frame locking rod 21 or the front frame locking rod 22), and the middle frame locking rod 21 and the front frame locking The flange 22 is slidable in the vertical direction along the through holes 21a to 21c and 22a to 22c.

  The locking mechanism actuating member 23 includes an attachment portion 27, a cylinder lock 28, and a cam 29 in which two protrusions 29a and 29b are formed. The outer cylinder 28b of the cylinder lock 28 is fixed to the attachment portion 27 along the front-rear direction of the pachinko machine 10 so that the keyhole of the cylinder lock 28 faces the machine surface side. The mounting portion 27 is provided on the inner side surface of the right frame portion 12a of the middle frame 12 by the crimping pins 26b and 26c to which the middle frame locking rod 21 and the front frame locking rod 22 are fixed. ). A cam 29 is fixed to a cylinder (inner cylinder portion) 28a of the cylinder lock 28, and the cam 29 is fixed to the outer cylinder 28b together with the cylinder 28a. The cam 29 is fixed to the side of the cylinder 28a where the keyhole is not formed.

  The protrusions 29a and 29b included in the cam 29 are formed so as to protrude in a direction perpendicular to the rotation direction (that is, from the center toward the outer periphery). In addition, the protrusion 29a is formed with the other protrusion 29b at an interval of approximately 90 degrees. When the cam 29 is fixed to the cylinder 28a, the protrusion 29a disposed at the upper part is bent in a substantially Z shape, and when the cylinder 28a is rotated, a locus drawn by the tip of the protrusion 29a, The locus drawn by the tip of the protrusion 29b is shifted in the front-rear direction of the pachinko machine 10.

  When the cam 29 is fixed to the cylinder 28a, the projection 29b disposed below the projection 29a is formed in the slit 12f formed in the middle frame 12 along the vertical direction and the middle frame locking rod 21. The engagement hole 31 formed in the front frame locking bar 22 can be engaged through the engagement hole 31. Therefore, when the cylinder 28a of the cylinder lock 28 is rotated counterclockwise (direction A shown in FIG. 5), the protrusion 29b engages with the engagement hole 30 of the front frame locking rod 22. When a force is further applied to rotate the cylinder 28a counterclockwise, the front frame locking bar 22 is slidable in the vertical direction and is pushed upward by the protrusion 29b.

  In addition, when the cam 29 is fixed to the cylinder 28a, the protrusion 29a disposed above the protrusion 29b causes the cylinder 28a to rotate in the clockwise direction (the direction opposite to the direction A shown in FIG. 5). It can be engaged with an engagement hole 31 formed in the middle frame locking rod 21 through a slit 12 f formed in the frame 12. For this reason, when the cylinder 28 a of the cylinder lock 28 is rotated clockwise, the protrusion 29 a engages with the engagement hole 31 of the inner frame locking rod 21. When a force is further applied to rotate the cylinder 28a clockwise, the cylinder 28a is pushed by the protrusion 29a and moves downward. As a result, the engagement between the middle frame collar 24 and the engagement piece 18 of the outer frame 11 is released, and the middle frame 12 can be released from the outer frame 11. Therefore, in the present embodiment, when the protrusion 29b rotates the cam 29 in the A direction, the driving force from the cam 29 is applied to the front frame locking rod 22 via the slit (through hole) 12f of the right frame 12a. It becomes the first protrusion that transmits and releases the engagement with the front frame 13. Further, when the protrusion 29a rotates the cam 29 in the direction opposite to the A direction, the driving force from the cam 29 is transmitted to the middle frame locking rod 21 through the slit (through hole) 12f of the right frame 12a. Thus, the second protrusion is released from the engagement with the middle frame 12.

  And the locking mechanism action | operation member 23 of the locking device 20 is accommodated in the accommodation recessed part 12e formed in the lower frame part 12d of the middle frame 12, as shown in FIG. The housing recess 12e is provided at the right end of the lower frame portion 12d, and is open on the machine surface side and the right side (right frame portion 12a side) of the pachinko machine. Specifically, the accommodation recess 12e has an L-shaped horizontal cross section. That is, the housing recess 12e is formed with a machine front side opening that opens to the machine front and a side opening that opens to the right frame 12a.

The side opening has a size that allows the locking mechanism operating member 23 installed in the right frame 12a to pass therethrough.

  The right opening (side opening) is closed by the right frame 12 a of the middle frame 12. Moreover, the opening part (machine surface side opening part) of the front side is obstruct | occluded by the cover member 32 which comprises the lower frame part 12d. The cover member 32 is formed with a through hole 32a for exposing a machine side portion of the cylinder lock 28 (that is, only the key hole). That is, the cover member 32 is formed so as to expose the machine front side portion (that is, only the keyhole) of the cylinder lock 28 and completely close the machine front side opening of the other housing recess 12e. In the present embodiment, the cover member 32 and the right frame portion 12a constitute a closing member. The opening on the machine front side has a size that allows the cylinder lock 28 accommodated in the accommodating recess 12e to pass therethrough, and the cylinder is opened while the side opening is closed by the right frame 12a. The lock 28 can be exchanged.

  Further, the locking device 20 is provided with an opening restriction mechanism K that restricts opening when closed. As shown in FIG. 5, the opening restriction mechanism K is formed between the first opening restriction member 33 fixed to the middle frame locking bar 21 and the middle frame locking bar 21 and the front frame locking bar 22 via the caulking pin 26b. The second opening restricting member 34 is provided.

  The first opening restriction member 33 is formed in a long and thin plate shape. One end (upper end) of the first opening restricting member 33 is rotatably fixed at a position located rearward (on the rear side of the machine) from the through hole 21b of the middle frame locking rod 21. At the other end (lower end), a contact portion 33a that protrudes to the front side of the pachinko machine 10 is formed so as to be in contact with the protrusion 29a. The contact portion 33a is formed so as to protrude obliquely downward. When the protruding portion 29a moves downward and presses the contact portion 33a, the first opening restricting member 33 has a pachinko machine centered on the fixed point. 10 is gradually rotated backward (in the direction C shown in FIG. 7). Moreover, the flange part 33b is formed in the 1st open control member 33 along the up-down direction. When the middle frame 12 is closed, the second opening restricting member 34 is brought into contact with the lower end of the flange portion 33b as shown in FIG. A spring 36 is connected to the front side of the upper end portion (upper end portion than the fixed point) of the first opening restriction member 33, and the first opening restriction member 33 moves to the front side of the pachinko machine 10 (C direction). The elastic force of the spring 36 is applied so as to rotate (in the opposite direction).

And the contact piece 34c which contact | abuts the lower end of the flange part 33b is formed in the protrusion part 34a arrange | positioned at the back side of the pachinko machine 10 so that it may protrude back. Further, a through hole 34d into which the caulking pin 26b is inserted is formed at the lower end of the second opening restriction member 34, and is fixed so as to be rotatable around the through hole 34d. In addition, a pressing portion 34 e that protrudes rearward is formed at the upper end of the second opening restriction member 34. The pressing portion 34e presses against a pressing piece 35 (see FIG. 6) provided on the outer frame 11 when closed. Then, on the rear side of the upper end portion of the second opening restriction member 34, the first opening restriction is performed so that the elastic force acts on the rear side (D direction shown in FIG. 7) of the pachinko machine 10 around the through hole 34d. A spring 36 connected to the upper end of the member 33 is connected.

  When the opening restriction mechanism K configured in this manner is closed, as shown in FIG. 7, the pressing portion 34 e is moved forward of the pachinko machine 10 by the pressing piece 35 of the inner frame 12 (the direction opposite to the D direction). The contact piece 34c is pressed against the lower end of the flange portion 33b. Thereby, even if the middle frame locking rod 21 is going to move downward, the flange portion 33b is engaged with the contact piece 34c, and the movement is restricted.

  In this state, when the cam 29 is rotated to move the protrusion 29a downward, as shown in FIG. 8, the protrusion 29a presses the contact portion 33a, and the first opening restricting member 33 is centered on the fixed point. It rotates to back (C direction). Thereby, the engagement state of the contact piece 34c and the flange part 33b is cancelled | released. For this reason, the middle frame locking rod 21 can be moved downward by moving the projection 29a downward and engaging with the engagement hole 31 of the middle frame locking rod 21. That is, the middle frame locking rod 21 can be moved downward, the engagement between the middle frame collar piece 24 and the engagement piece 18 can be released, and the middle frame 12 can be opened.

  When the middle frame 12 is opened, as shown in FIG. 9, the pressing portion 34 e of the second opening restriction member 34 moves rearward (D direction) by the elastic force of the spring 36. When the middle frame 12 is closed from this state, the pressing portion 34e is pushed to the front side of the pachinko machine 10 (the direction opposite to the D direction) by the pressing piece 35 of the outer frame 11. Thereby, the contact piece 34c located at the lower end of the second opening restriction member 34 comes into contact with the flange portion 33b. That is, the opening of the middle frame 12 is restricted. As described above, in order to open the middle frame 12, it is necessary to move the middle frame locking bar 21 after rotating the cam 29 to release the release restriction mechanism K, and to close the middle frame 12. At that time, the opening restriction mechanism K functions to automatically restrict the opening of the middle frame 12.

Hereinafter, specific configurations of the various control boards 71 to 76 will be described.
First, the main control board 71 will be described.
As shown in FIG. 17, the main control board 71 is provided with a main CPU 71a, a ROM 71b, and a RAM 71c. The main CPU 71a updates various random number values at predetermined intervals. The ROM 71b stores a main control program for controlling the pachinko machine 10 and a plurality of types of effect patterns. The RAM 71c stores (sets) various pieces of information (such as random number values) that can be appropriately rewritten during the operation of the pachinko machine 10.

  The variation pattern is a game effect (display effect, light effect, sound effect) from when the symbol starts to change (start of the symbol combination game) to when all the symbols are displayed (the symbol combination game ends). The pattern used as the base of is shown. Further, the plurality of types of variation patterns are classified into variation patterns for a big hit effect and variation patterns for a loss effect.

  The jackpot effect is an effect in which the symbol combination game is developed so as to finally stop the symbol combination of the jackpot. The outlier effect is an effect in which the symbol combination game is developed so as to stop the outlier symbol combination.

  The main CPU 71a is connected to the unlock detection sensor 40, and receives an unlock signal indicating that the cylinder lock 28 is unlocked from the unlock detection sensor 40. The main CPU 71a is connected to the door opening detection switch 41, and receives an opening signal indicating that the front frame 13 or the middle frame 12 is opened from the door opening detection switch 41.

  The main control board 71 is connected to a RAM clear switch circuit 91 for erasing various control information (stored contents) stored and held in the RAM 71 c and appropriately rewritten during the operation of the pachinko machine 10. A RAM clear switch 90 is connected to the RAM clear switch circuit 91 and is operated when it is desired to delete various control information (stored contents).

  In the present embodiment, the RAM clear switch 90 is provided on the rear side of the machine so that only operations of a game shop clerk are allowed. When the RAM clear switch 90 is operated, the RAM clear switch circuit 91 stores data in the RAM 71c. An initialization instruction signal for instructing erasure (initialization processing) of the stored contents is output. When an initialization instruction signal is output from the RAM clear switch circuit 91, initialization processing is executed. Therefore, the RAM clear switch 90 and the RAM clear switch circuit 91 according to the present embodiment serve as a reset unit that outputs a reset signal (initialization instruction signal) instructing execution of the initialization process.

The main CPU 71a executes various processes such as a winning process and a variation pattern determining process based on the main control program.
First, the winning process will be described with reference to FIG.

  The main CPU 71a determines whether or not a game ball winning is detected at predetermined time intervals (step S11). That is, the main CPU 71a determines whether or not a start opening prize detection signal output by a winning detection means constituted by the start winning opening 56 and the start opening sensor SE1 is input. When the determination result is negative (when no winning is detected), the main CPU 71a ends the input process. On the other hand, when the determination result is affirmative (when winning detection is present), the main CPU 71a determines whether or not the number of reserved storage stored in the RAM 71c is less than the upper limit (4 in the present embodiment) (step). S12). If this determination result is negative (holding memory count = 4), the main CPU 71a ends the winning process.

  On the other hand, if the determination result is affirmative (if the number of reserved memories <4), the main CPU 71a adds “1” (+1) to the number of reserved memories stored in the RAM 71c and rewrites the number of reserved memories (step S13). ). Subsequently, the main CPU 71a reads and acquires the value of the big hit random number from the RAM 71c, and sets the read value of the big hit random number in a predetermined storage area of the RAM 71c associated with the reserved storage number (step S14). Further, the main CPU 71a acquires the value of the jackpot symbol random number from the RAM 71c, and sets the read value of the jackpot symbol random number in a predetermined storage area of the RAM 71c associated with the reserved storage number (step S14). Note that the big hit random number and the big hit symbol random number are random numbers that are sequentially updated by the main CPU 71a at predetermined intervals. The main CPU 71a sets the updated value in the setting area of the RAM 71c and rewrites the value before the update. Yes. Then, the main CPU 71a ends the winning process.

Next, the variation pattern determination process will be described with reference to FIG.
First, the main CPU 71a determines whether or not the number of reserved memories is greater than “0” at predetermined time intervals (step S21). If the determination result of step S21 is negative (when the number of stored memories = 0), there is no pending symbol combination game, and the main CPU 71a ends the variation pattern determination process. On the other hand, when the determination result of step S21 is affirmative (when the number of stored storages> 0), the main CPU 71a determines whether or not the symbol is in a variable display, that is, whether or not the symbol combination game is being performed ( Step S22). When the determination result of step S22 is affirmative (when the symbol combination game is in progress), the main CPU 71a ends the variation pattern determination process. On the other hand, if the determination result in step S22 is negative (when the symbol combination game is not in progress), the main CPU 71a stores the big hit random number stored in the ROM 71b in association with the reserved storage number and stored in the RAM 71c. A big hit determination is performed by determining whether or not the determination value matches (step S23). In the present embodiment, the probability that the determination result of the jackpot determination is affirmative (the jackpot probability) is 1/300.

  When the determination result of the jackpot determination is affirmative (in the case of a jackpot), the main CPU 71a reads the value of the jackpot symbol random number stored in the RAM 71c in association with the reserved storage number. Then, the main CPU 71a determines a final stop symbol based on the value of the jackpot symbol random number so that all the columns become the same type symbol (step S24). At the same time, the main CPU 71a determines a variation pattern from the variation patterns for the big hit effect (step S25).

  The main CPU 71a which has determined the variation pattern and the final stop symbol outputs a predetermined control command to the overall control board 72 at a predetermined timing (step S26). Specifically, the main CPU 71a first outputs a variation pattern designation command for designating a variation pattern and instructing the start of symbol variation. Next, the main CPU 71a outputs a symbol designation command for designating a final stop symbol for each column. Further, the main CPU 71a subtracts (-1) “1” from the reserved storage number stored in the RAM 71c to rewrite the reserved storage number (step S27). After that, the main CPU 71a instructs a change stop based on the change time set in the specified change pattern, and outputs an all symbol stop command for ending the symbol combination game.

  On the other hand, when the determination result of the jackpot determination in step S23 is negative (in the case of loss), the main CPU 71a determines the final stop symbol so that the symbols in all the rows are not the same type (step S28). Then, the main CPU 71a determines a variation pattern from the variation patterns for the offending effect (step S29). Then, the main CPU 71a proceeds to the process of step S26 and outputs a predetermined control command at a predetermined timing. Then, the main CPU 71a proceeds to the process of step S27, and subtracts “1” from the reserved memory number (−1) to rewrite the reserved memory number.

  Further, the main CPU 71a stores in the RAM 71c the number of times of input of a start port winning detection signal indicating that a game ball has won the start port sensor SE1. That is, when the main CPU 71a receives the start port winning detection signal from the start port sensor SE1, the main CPU 71a rewrites the RAM 71c by adding 1 to the start port winning number indicating the number of input of the start port winning detection signal. Then, each time the main CPU 71a outputs a first payout instruction command for instructing the payout control board 76 to pay out a predetermined number (for example, 3) of game balls (prize balls) in the output process, The RAM 71c is rewritten by subtracting 1 from the number of winnings.

  Similarly, the main CPU 71a stores, in the RAM 71c, the number of times of receiving a big winning opening winning detection signal indicating that a game ball has won the big winning opening sensor SE2. That is, when the main CPU 71a receives the big prize opening winning detection signal from the big winning opening sensor SE2, the main CPU 71a rewrites the RAM 71c by adding 1 to the number of big winning opening winnings indicating the number of input of the big winning opening winning detection signal. Then, each time the main CPU 71a outputs a second payout instruction command for instructing the payout control board 76 to pay out a predetermined number (for example, 10) of game balls (prize balls) in the output process, The RAM 71c is rewritten by subtracting 1 from the number of winning prizes.

  Next, the overall control board 72 will be described. As shown in FIG. 17, the overall control board 72 is provided with an overall CPU 72a. The general CPU 72a sequentially updates various random number values at predetermined intervals. Further, a ROM 72b and a RAM 72c are connected to the overall CPU 72a.

Yes. The RAM 73c stores (sets) various information that can be appropriately rewritten during the operation of the pachinko machine 10.

  When the sub CPU 73a receives a control command from the overall control board 72 (overall CPU 72a), the sub CPU 73a performs control according to the input control command based on the display control program. Specifically, when the sub CPU 73a inputs the variation pattern designation command, the display content of the variable display H is displayed so that the symbol combination game is displayed with the variation pattern designated by the variation pattern designation command. To control. When the sub CPU 73a inputs the all symbol stop command, the sub CPU 73a controls the display content of the variable display H so that the variable display H stops the symbol combination designated by the inputted symbol designation command. By this control, the symbol combination game is performed on the variable display H.

Next, the lamp control board 74 will be described.
The lamp control board 74 includes a sub CPU 74a, and a ROM 74b and a RAM 74c are connected to the sub CPU 74a. The ROM 74b stores a light emission control program and the like for controlling the light emission modes (lighting (flashing) / lighting timing, etc.) of the frame lamp 51 and the game board lamp 52. The RAM 74c stores (sets) various information that can be appropriately rewritten during the operation of the pachinko machine 10.

  When the sub CPU 74a receives a control command from the overall control board 72 (overall CPU 72a), the sub CPU 74a performs control according to the input control command based on the light emission control program. Specifically, when the sub CPU 74a inputs a variation pattern designation command, the sub CPU 74a controls the light emission modes of the frame lamp 51 and the game board lamp 52 in accordance with the variation pattern designated by the variation pattern designation command. By this control, a light emission effect according to the symbol combination game performed on the variable display H is performed.

Next, the voice control board 75 will be described.
The audio control board 75 includes a sub CPU 75a, and a ROM 75b and a RAM 75c are connected to the sub CPU 75a. The ROM 75b stores a sound control program, various sound data, and the like for controlling sound output modes (such as sound output timing) of the speakers 53a and 53b. The RAM 75c stores (sets) various information that can be appropriately rewritten during the operation of the pachinko machine 10.

  When the sub CPU 75a receives a control command from the overall control board 72 (overall CPU 72a), the sub CPU 75a performs control according to the input control command based on the voice control program. Specifically, when the sub CPU 75a inputs the variation pattern designation command, the sub CPU 75a outputs sound from the speakers 53a and 53b according to the variation pattern designated by the variation pattern designation command. By this control, a sound effect according to the symbol combination game performed on the variable display H is performed.

Next, the payout control board 76 will be described.
The payout control board 76 includes a sub CPU 76a, and a ROM 76b and a RAM 76c are connected to the sub CPU 76a. The ROM 76b stores a payout control program for controlling payout of game balls from the payout device 77. The RAM 76c stores (sets) various information that can be appropriately rewritten during the operation of the pachinko machine 10.

  The sub CPU 76a of the payout control board 76 is connected to a RAM clear switch circuit 91 for erasing various control information (stored contents) stored and held in the RAM 76c and appropriately rewritten during the operation of the pachinko machine 10. . When the RAM clear switch 90 connected to the RAM clear switch circuit 91 is operated, the RAM clear switch circuit 91 outputs an initialization instruction signal for instructing erasure (initialization processing) of the stored contents stored in the RAM 76c. It has become so. When the initialization instruction signal is output from the RAM clear switch circuit 91, the initialization process of the RAM 76c is executed.

  Then, when a predetermined control command is input from the main CPU 71a at a predetermined timing, the sub CPU 76a performs control according to the input control command based on the payout control program. For example, when the sub CPU 76a of the payout control board 76 receives the first payout instruction command from the main CPU 71a, the sub CPU 76a adds the predetermined number instructed by the first payout instruction command to the payout remaining number indicating the payout remaining number of prize balls, The data is stored in a RAM 76c provided on the payout control board 76. Similarly, when the sub CPU 76a of the payout control board 76 inputs the second payout instruction command, the sub CPU 76a adds the predetermined number instructed by the second payout instruction command to the payout remaining number, and enters the RAM 76c provided in the payout control board 76. Remember. Further, when the payout remaining number is 1 or more, the sub CPU 76a of the payout control board 76 degausses the payout solenoid 77l, disengages the stopper 77j, and releases the rotation restriction of the ball feed sprocket 77e. 77 is controlled by a control signal. Thereby, the payout device 77 pays out the game ball by the rotation of the ball feed sprocket 77e. The sub CPU 76a is connected to a payout counting sensor 77i, and decrements the payout remaining number by 1 every time a payout of game balls is detected from the payout counting sensor 77i. Further, when the payout remaining number is 0, or when an error signal is input from the main control board, the sub CPU 76a excites the payout solenoid 77l, engages the stopper 77j, and restricts the rotation of the ball feed sprocket 77e. As described above, the dispensing device 77 is controlled by the control signal.

  In this embodiment, the main CPU 71a opens the front frame 13 or the middle frame 12 in a normal procedure based on the input order of the opening signal from the door opening detection switch 41 and the unlocking signal from the unlocking detection sensor 40. It is determined whether or not it has been performed, and if it is opened by an unauthorized procedure, it is regarded as unauthorized opening (unauthorized act) so as not to cause an undue disadvantage to the game store. This will be described in detail below.

  The main CPU 71a executes a fraud prevention process (FIG. 20) every predetermined cycle. In this process, the main CPU 71a first determines whether or not an unlock signal has been input from the unlock detection sensor 40 (step S31). When the determination result is affirmative, the main CPU 71a sets “1” to the unlock flag F1 in a predetermined storage area of the RAM 71c (step S32). The unlocking flag F1 is a flag indicating whether or not the cylinder lock 28 of the locking device 20 is unlocked. When “0” is set, the unlocking flag F1 indicates that the cylinder lock 28 is locked. When “1” is set, it indicates that the cylinder lock 28 is unlocked. When it is determined that the unlocking flag F1 is set to “1” and the front frame 13 or the middle frame 12 is opened, the input of the release signal is interrupted, and the front frame 13 or the middle frame 12 is closed. The main CPU 71a sets “0” to the unlock flag F1.

  When the process of step S31 or step S32 ends, the main CPU 71a determines whether or not an opening signal is input from the door opening detection switch 41 (step S33). If the determination result is affirmative, the main CPU 71a determines whether or not “1” is set in the unlock flag F1 (step S34). If the determination result is affirmative, the main CPU 71a ends the fraud prevention process.

  On the other hand, if the determination result in step S34 is negative, the main CPU 71a determines that the front frame 13 or the middle frame 12 has been illegally released (unauthorized release), and outputs an error signal indicating that an illegal act has occurred. The data is output to the overall control board 72 and the payout control board 76 (step S35). When the error signal is input, the overall control board 72 outputs an error signal to each of the control boards 73 to 75. Sub CPU73a-75a of each control board 73-75 will perform error alerting | reporting that the front frame 13 or the middle frame 12 was open | released illegally, if an error signal is input. Specifically, the display control board 73 controls the variable display H so that the variable display H displays a character string “Illegal opening”. The lamp control board 74 controls the frame lamp 51 so that the frame lamp 51 blinks. The audio control board 75 controls the speakers 53a and 53b so that the buzzer sound is output from the speakers 53a and 53b.

  In addition, when the sub CPU 76a of the payout control board 76 inputs an error signal, the sub CPU 76a controls the payout device 77 so as not to pay out the game ball. Further, the sub CPU 76a of the payout control board 76 stores the payout remaining number at the time when the payout is stopped in a predetermined storage area of the RAM 76c. Further, the sub CPU 76 a of the payout control board 76 outputs a firing stop instruction signal for instructing the firing control board 78 to stop the firing of the game ball. Thereby, the launch control board 78 controls the launch device 9 so as to stop the launch of the game ball. Further, the main CPU 71a stores the current start port winning number and the big winning port winning number in a predetermined storage area of the RAM 71c (step S36). Then, the main CPU 71a sets “1” to the restriction flag F2 indicating that the payout of game balls is restricted (step S37), and ends the fraud prevention process.

  When “1” is set in the restriction flag F2, the main CPU 71a does not execute the variation pattern determination process thereafter, and does not output the variation pattern designation command. In addition, when the restriction flag F2 is set to “1”, the main CPU 71a sets the first payout instruction command and the second payout instruction command even if the start opening winning number or the big winning opening winning number is 1 or more. Is not output.

  On the other hand, even if the restriction flag F2 is set to “1”, the main CPU 71a is configured to execute a winning process, and every time a game ball wins the start winning opening 56 until the reserved memory number reaches the upper limit. In addition, the big hit random number and the big hit symbol random number are stored in relation to the reserved storage number. Further, even when the restriction flag F2 is set to “1”, the main CPU 71a adds 1 to the start opening prize number indicating the number of input of the start opening prize detection signal when the start opening prize detection signal is input from the start opening sensor SE1. Then, the RAM 71c is rewritten. Even when the restriction flag F2 is set to “1”, when the main CPU 71a inputs a big prize opening prize detection signal from the big prize opening sensor SE2, the big prize opening prize indicating the number of input of the big prize opening prize detection signal is shown. The RAM 71c is rewritten by adding 1 to the number of times.

  As described above, when the unlocking signal from the door opening detection switch 41 is input before the unlocking signal from the unlocking detection sensor 40 is input, the front frame 13 or the middle frame is opened although the locking device 20 is not unlocked. It is considered that the frame 12 has been opened. Then, after the locking device 20 is unlocked, the front frame 13 or the inner frame 12 is opened by a normal opening procedure by a person at the game store side, even though the locking device 20 is not unlocked. The opening of the front frame 13 or the middle frame 12 is considered an illegal act. Therefore, in this embodiment, when the opening signal from the door opening detection switch 41 is input before the unlocking signal from the unlocking detection sensor 40 is input, the main CPU 71a determines that the opening is unauthorized and outputs an error signal. And instruct to stop paying out the game balls. In response to this, the payout control board 76 stops paying out the game balls, so that the game shop can prevent disadvantages due to fraud. Moreover, in this embodiment, the main control board 71 provided with the main CPU 71a constitutes an unauthorized opening determination unit that determines unauthorized opening. Further, the main control board 71 constitutes a control means for executing various processes based on the signals.

  Further, the main control board 71, the unlock detection sensor 40, and the door open detection switch 41 constitute an abnormal state detection means for detecting an abnormal state. Further, the RAM 71c of the main control board 71 constitutes a payout information storage means for storing information relating to the payout amount of the game ball (for example, the number of winnings at the start opening). In addition, the RAM 76c of the payout control board 76 serves as a remaining amount storage unit.

Next, the game resumption process (FIG. 21) will be described.
The main CPU 71a determines whether or not the restriction flag F2 is set (step S41). If this determination result is negative, the main CPU 71a ends the game restart process. On the other hand, when the determination result of step S41 is affirmative, the main CPU 71a determines whether or not an unlock signal is input from the unlock detection sensor 40 (step S42). When the determination result is affirmative, the main CPU 71a sets “1” to the unlock flag F1 in a predetermined storage area of the RAM 71c (step S43).

  After completing the processing of step S42 or step S43, the main CPU 71a determines whether or not an opening signal is input from the door opening detection switch 41 (step S44). If the determination result is affirmative, the main CPU 71a determines whether or not “1” is set in the unlock flag F1 (step S45). When the determination result of step S45 is negative, the main CPU 71a ends the game restart process.

  On the other hand, if the determination result in step S45 is affirmative, the main CPU 71a determines that the front frame 13 or the middle frame 12 has been opened by a normal procedure and determines that the main frame 71a is normally opened, and sends an error release signal to the overall control board 72 and the payout control. It outputs to the board | substrate 76 (step S46).

  When receiving the error release signal, the overall control board 72 outputs an error release signal to each of the control boards 73 to 75. Sub CPU73a-75a of each control board 73-75 will complete | finish an error alerting | reporting, if an error cancellation signal is input.

  When the sub CPU 76a of the payout control board 76 receives an error cancel signal from the main CPU 71a, the sub CPU 76a reads out the payout remaining number which is the number of unpaid award balls stored in the RAM 76c, and the number of awards corresponding to the payout remaining number. The payout device 77 is controlled to pay out the ball, and the payout of the prize ball is resumed. Further, the sub CPU 76a of the payout control board 76 outputs a release signal for releasing the stop of the firing to the launch control board 78 to release the stop of the game ball. Thereby, the launch control board 78 releases the stop of the game ball launch and controls the launch device 9 to launch the game ball.

  Further, the main CPU 71a reads out the start opening prize number from the RAM 71c, outputs a first payout instruction signal corresponding to the start opening prize number, reads out the big winning opening prize number from the RAM 71c, and corresponds to the large winning opening prize number. The second payout instruction signal is output (step S47). Then, the main CPU 71a clears the setting of the restriction flag (step S48) and ends the game restart process.

  As described above, the act of opening the front frame 13 or the middle frame 12 after the locking device 20 is unlocked is a regular opening by the game store side or the like. After this is done, it can be determined that there is no fraud. Therefore, in the present embodiment, the main CPU 71a determines that the door is normally opened when the unlock signal from the unlock detection sensor 40 is input after the unlock flag sensor 2 is input after the restriction flag F2 is set. Then, an error release signal is output to instruct to resume paying out the game balls. In response to this, the payout control board 76 resumes payout of the game ball, so that the game shop can prevent disadvantages due to fraud.

  When the payout is stopped, the unpaid game balls are stored and are paid out after the payout is resumed, so there is no disadvantage to the player. Further, when it is determined that an illegal act has been performed and it is desired to erase an unpaid game ball, it can be initialized by operating the RAM clear switch 90. Further, in the present embodiment, the main control board 71 constitutes a regular opening determination unit that determines normal opening. Further, the main control board 71 constitutes an error canceling means for outputting an error canceling signal.

As described above in detail, the present embodiment has the following effects.
(1) After the locking device 20 is unlocked, the front frame 13 or the middle frame 12 is opened in a normal opening procedure by a person on the game store side. For this reason, it can be considered that it is an unauthorized operation to open the front frame 13 or the middle frame 12 even though the locking device 20 is not unlocked. Therefore, in this embodiment, an unlock detection sensor 40 that detects unlocking of the locking device 20 and a door open detection switch 41 that detects the opening of the front frame 13 or the middle frame 12 are provided, and input from the unlock detection sensor 40 is performed. It was determined whether or not it was illegally opened based on the input order of the unlocking signal and the opening signal input from the door opening detection switch 41. When the main CPU 71a determines that it is illegally released, the main CPU 71a outputs an error signal to the payout control board 76 to instruct to stop paying out the game balls. As a result, the game balls are not paid out. Therefore, even if the big prize opening door 57 is opened and the game balls are won in the big prize opening 58, illegal game balls can be prevented from being paid out. Therefore, since it becomes impossible to obtain a game ball by an illegal act, the game store side is not damaged and can prevent fraud.

  (2) If the correct opening procedure of opening the front frame 13 or the middle frame 12 is performed after the locking device 20 is unlocked, it can be considered that the person at the amusement store has operated. . Therefore, after stopping the payout of the game ball (after setting the regulation flag F2), if the signals are input in the order of the unlock signal → the release signal, it is determined that the person at the game store side has operated and the cheating has disappeared can do. When the signals are input in the order of the unlock signal → the release signal, the main CPU 71a outputs an error release signal to release the game ball payout stop. Thereby, the player can play a game normally. Further, since it is not necessary to provide a switch or the like for releasing the stop, development cost and labor can be reduced.

  (3) When the error control signal is input, the payout control board 76 outputs a firing stop signal to cause the firing control board 78 to stop launching the game ball. In this way, by stopping the launch of the game ball, it is possible to prevent an illegal act such as causing the game ball to enter the start winning opening in an unauthorized state. In addition, since the launch of the game ball in a situation where the game ball is not paid out is stopped, it is possible to prevent the play of the game ball that is useless for the player.

  (4) When the main CPU 71a determines that it is unauthorized opening, the main CPU 71a outputs an error signal to the voice control board 75 via the overall control board 72 and outputs an error notification as voice. As a result, when the front frame 13 or the middle frame 12 is illegally opened even though the locking device 20 is not unlocked, the misconduct can be notified to surrounding people by error notification. Can be suppressed.

  (5) When the restriction flag F2 is set, the main CPU 71a stores the number of start-up winnings and the number of times of winning a big winning opening. The first payout instruction signal and the second payout instruction signal are output based on the readout, the start opening winning number and the big winning opening winning number. Thereby, when the payout of the game ball is resumed, it is possible to pay out the game ball according to the number of start-up winnings and the number of winnings of the big winnings before the stop. The sub CPU 76a of the payout control board 76 stores the payout remaining number in the RAM 76c when the error signal is input, and reads the payout remaining number when the error release signal is input, and based on the payout remaining number, the game ball Was paid out. That is, if a normal operation is performed in which the front frame 13 or the middle frame 12 is opened after the locking device 20 is unlocked, it is considered that the game store side has operated, that is, the fraudulent act has disappeared. As a result, game balls that have not been paid out due to the suspension of payout of game balls are now paid out. As a result, the player does not suffer an unfair disadvantage. Further, since the payout of the game ball is resumed, the player will not suffer any disadvantage when the game is resumed.

  (6) By operating the RAM clear switch 90, the stored contents of the RAM 71c of the main control board 71 and the stored contents of the RAM 76c of the payout control board 76 can be initialized. For this reason, when there is a game ball winning based on cheating (number of start opening winnings and number of large winning opening winnings) or unpaid gaming balls (remaining payout), the storage contents and payout of the RAM 71c of the main control board 71 The stored contents of the RAM 76c of the control board 76 can be initialized. Therefore, after the game ball is paid out again, unpaid game media due to the illegal act is not paid out, and a disadvantage caused by the illegal act can be avoided.

  (7) The cylinder lock 28 was housed in the housing recess 12e, and the opening of the housing recess 12e was closed with a cover member 32 or the like. Thereby, even if the front frame 13 is opened, the cylinder lock 28 and the unlock detection sensor 40 are not exposed to the outside. For this reason, it is possible to make it difficult to unlock and destroy by an unauthorized act, and to cause the unlock detection sensor 40 to malfunction by an unauthorized act (that is, although the locking device 20 is not unlocked). Making it difficult to operate as if unlocked).

  (8) The door opening detection switch 41 is housed in a housing portion provided in the middle frame 12, and when the front frame 13 and the middle frame 12 are closed, the housing portion is closed by the front frame 13 and the middle frame 12. It was to so. For this reason, since the door opening detection switch 41 is not exposed to the outside, it is possible to make an illegal act such as the opening of the front frame 13 or the middle frame 12 not detected.

  (9) The housing recess 12e is formed in the lower frame portion 12d located below the game board 14, and the locking mechanism actuating member 23 is housed in the housing recess 12e. For this reason, compared with the case where the locking mechanism action | operation member 23 is arrange | positioned to the side of the game board 14, the area of the game area | region 14a can be enlarged. Therefore, as compared with the case where the locking mechanism actuating member 23 is arranged on the side of the game board 14, more effect devices can be installed on the game board 14 (or a larger effect device can be installed on the game board 14. ). For example, compared with the case where the locking mechanism operation member 23 is arrange | positioned to the side of the game board 14, the big variable display H can be mounted in the game board 14. FIG.

  (10) Since the middle frame locking rod 21 and the front frame locking rod 22 move in the vertical direction when engaging with the middle frame 12 or the front frame 13 (or when releasing the engagement), a space for that is required. Become. Therefore, in the present embodiment, the locking mechanism actuating member 23 is installed inside the right frame portion 12a (on the lower frame portion 12d side), and the middle frame locking rod 21 and the front frame locking rod 22 are installed outside the right frame portion 12a. did. For this reason, the accommodation recessed part 12e can be obstruct | occluded reliably.

  (11) The machine surface side opening is formed larger than the longitudinal section of the cylinder 28a. That is, the machine-side opening has a size that allows the cylinder 28a (and the cam 29, the unlock detection sensor 40, etc. fixed to the cylinder 28a) accommodated in the accommodating recess 12e to pass therethrough. . For this reason, the cylinder 28a, the cam 29, and the unlocking detection sensor 40 can be exchanged from the machine-surface-side opening in a state where the side opening is closed by the right frame 12a. Therefore, when exchanging the cylinder 28a, the cam 29, and the unlocking detection sensor 40, it is not necessary to disassemble the inner frame 12 and the like, which can be performed with a minimum of labor.

(Second embodiment)
Next, a second embodiment embodying the present invention will be described. In addition, the same code | symbol as 1st embodiment is attached | subjected to the structure similar to 1st embodiment, the detailed description and drawing are abbreviate | omitted or simplified.

  In the second embodiment, the main CPU 71a opens the front frame 13 or the middle frame 12 in a normal procedure based on the input order of the opening signal from the door opening detection switch 41 and the unlocking signal from the unlocking detection sensor 40. It is determined whether or not the game has been released, and if it is released through an illegal procedure, it is regarded as unauthorized release (unauthorized act) so that the game cannot be performed. This will be described in detail below.

  The main CPU 71a executes a fraud prevention process (FIG. 22) every predetermined period. In this process, the main CPU 71a first determines whether or not an unlock signal has been input from the unlock detection sensor 40 (step S131). If this determination result is affirmative, the main CPU 71a sets “1” to the unlock flag F1 in a predetermined storage area of the RAM 71c (step S132). The unlock flag F1 is a flag indicating whether or not the cylinder lock 28 of the locking device 20 has been unlocked.

  When the process of step S131 or step S132 ends, the main CPU 71a determines whether or not an opening signal is input from the door opening detection switch 41 (step S133). If the determination result is affirmative, the main CPU 71a determines whether or not “1” is set in the unlocking flag F1 (step S134). If the determination result is affirmative, the main CPU 71a ends the fraud prevention process.

  On the other hand, if the determination result in step S134 is negative, the main CPU 71a determines that the front frame 13 or the middle frame 12 has been illegally opened (i.e., has been illegally released), and outputs an error signal indicating that an illegal act has occurred. The data is output to the overall control board 72 and the payout control board 76 (step S135). When the error signal is input, the overall control board 72 outputs an error signal to each of the control boards 73 to 75. Sub CPU73a-75a of each control board 73-75 will perform error alerting | reporting that the front frame 13 or the middle frame 12 was open | released illegally, if an error signal is input. Specifically, the display control board 73 controls the variable display H so that the variable display H displays a character string “Illegal opening”. The lamp control board 74 controls the frame lamp 51 so that the frame lamp 51 blinks. The audio control board 75 controls the speakers 53a and 53b so that the buzzer sound is output from the speakers 53a and 53b.

  In addition, when the sub CPU 76a of the payout control board 76 inputs an error signal, the sub CPU 76a controls the payout device 77 so as not to pay out the game ball. Further, the sub CPU 76a of the payout control board 76 stores the payout remaining number at the time when the payout is stopped in a predetermined storage area of the RAM 76c. Further, the sub CPU 76 a of the payout control board 76 outputs a firing stop instruction signal for instructing the firing control board 78 to stop the firing of the game ball. Thereby, the launch control board 78 controls the launch device 9 so as to stop the launch of the game ball.

Further, the main CPU 71a stores the current start opening winning number and the large winning opening number in a predetermined storage area of the RAM 71c (step S136).
Further, the main CPU 71a sets “1” to the invalid flag F3 indicating that the input signal is invalid (step S137), and ends the fraud prevention process. When “1” is set in the invalid flag F3, the main CPU 71a invalidates the input even if the start opening winning detection signal and the big winning opening winning detection signal are output from the starting opening sensor SE1 and the big winning opening sensor SE2. It is supposed to be.

  Specifically, when the invalid flag F3 is set to “1”, the main CPU 71a does not execute the winning process, and even if the starting port winning detection signal is input from the starting port sensor SE1, the big hit random number and the big hit symbol random number No longer get. Further, the main CPU 71a updates the numerical values of the number of start opening winning prizes and the number of large winning opening even if the start opening winning detection signal and the big winning opening winning detection signal are output from the starting opening sensor SE1 and the big winning opening sensor SE2. Will not add). Further, the main CPU 71a does not output the first payout instruction command and the second payout instruction command based on the start opening winning number and the large winning opening number. Further, the main CPU 71a does not execute the variation pattern determination process and does not output a variation pattern designation command. It should be noted that the start opening winning number, the big winning opening winning number, the big hit random number, the big hit symbol random number and the like stored in the RAM 71c are held until the error is canceled or initialized.

Next, the game resumption process (FIG. 23) will be described.
The main CPU 71a determines whether or not the invalid flag F3 is set (step S141). Henceforth, since the process to step S142-step S147 is the same as that of step S42-step S47 of 1st embodiment, it abbreviate | omits.

  When the process of step S147 ends, the main CPU 71a clears the invalid flag setting (step S148), and ends the game restart process. As a result, the main CPU 71a receives the start opening prize detection signal and the big prize opening prize detection signal when the start opening prize detection signal and the big prize opening prize detection signal are output from the start opening sensor SE1 and the big prize opening sensor SE2. To come.

As described above in detail, this embodiment has the following effects in addition to the effects (1) to (11) of the first embodiment.
(12) When the main CPU 71a determines that the opening of the front frame 13 or the middle frame 12 is unauthorized opening, the execution of the game effect is stopped by invalidating the signal input by the main CPU 71a. As a result, the gaming state (for example, a big hit state, a probability variation state in which the big hit lottery probability is increased) cannot be made advantageous to the player due to fraud, and the gaming store side will not be damaged and illegal. Can be prevented.

(Third embodiment)
Next, a third embodiment embodying the present invention will be described. In addition, the same code | symbol as 1st embodiment is attached | subjected to the structure similar to 1st embodiment, the detailed description and drawing are abbreviate | omitted or simplified.

  In the third embodiment, the main CPU 71a opens the front frame 13 or the middle frame 12 in a normal procedure based on the input order of the opening signal from the door opening detection switch 41 and the unlocking signal from the unlock detection sensor 40. It is determined whether or not the game has been released, and if it is released through an illegal procedure, it is regarded as unauthorized release (unauthorized act) so that the game cannot be performed. This will be described in detail below.

  The main CPU 71a executes a fraud prevention process (FIG. 24) every predetermined cycle. Since the process of step S231-step S234 is the same as the process of step S31-step S34 of 1st embodiment, description is abbreviate | omitted.

  If the determination result in step S134 is negative, the main CPU 71a determines that the front frame 13 or the middle frame 12 has been illegally released (unauthorized release), and performs overall control of an error signal indicating that an illegal act has occurred. The output is made to the substrate 72 (step S235). When the error signal is input, the overall control board 72 outputs an error signal to each of the control boards 73 to 75. Sub CPU73a-75a of each control board 73-75 will perform the error alerting | reporting which alert | reports that the front frame 13 or the middle frame 12 was open | released illegally, if an error signal is input.

  Further, the main CPU 71a sets “1” to the invalid flag F3 indicating that the input signal is invalid (step S236), and ends the fraud prevention process. When “1” is set in the invalid flag F3, the main CPU 71a invalidates the input even if the start opening winning detection signal and the big winning opening winning detection signal are output from the starting opening sensor SE1 and the big winning opening sensor SE2. It is supposed to be.

  Specifically, when the invalid flag F3 is set to “1”, the main CPU 71a does not execute the winning process, and even if the starting port winning detection signal is input from the starting port sensor SE1, the big hit random number and the big hit symbol random number No longer get. Further, the main CPU 71a updates the numerical values of the number of start opening winning prizes and the number of large winning opening even if the start opening winning detection signal and the big winning opening winning detection signal are output from the starting opening sensor SE1 and the big winning opening sensor SE2. Will not add). Further, the main CPU 71a does not output the first payout instruction command and the second payout instruction command based on the start opening winning number and the large winning opening number. Further, the main CPU 71a does not execute the variation pattern determination process and does not output a variation pattern designation command. It should be noted that at the time of error determination, the start opening winning number, the big winning opening winning number, the big hit random number, the big hit symbol random number, etc. stored in the RAM 71c are initialized as they are.

Next, the game resumption process (FIG. 25) will be described.
The main CPU 71a determines whether or not the invalid flag F3 is set (step S241). If this determination result is negative, the main CPU 71a ends the game restart process. On the other hand, when the determination result of step S241 is affirmative, the main CPU 71a determines whether or not an unlock signal is input from the unlock detection sensor 40 (step S242). If this determination result is affirmative, the main CPU 71a sets “1” to the unlock flag F1 in a predetermined storage area of the RAM 71c (step S243).

  After the process of step S242 or step S243 is completed, the main CPU 71a determines whether or not an opening signal is input from the door opening detection switch 41 (step S244). If this determination result is affirmative, the main CPU 71a determines whether or not “1” is set in the unlock flag F1 (step S245). When the determination result of step S245 is negative, the main CPU 71a ends the game restart process.

  On the other hand, if the determination result in step S245 is affirmative, the main CPU 71a determines that the front frame 13 or the middle frame 12 has been opened by a normal procedure, determines that the frame is normally opened, and outputs an error release signal to the overall control board 72. (Step S246). When receiving the error release signal, the overall control board 72 outputs an error release signal to each of the control boards 73 to 75. Sub CPU73a-75a of each control board 73-75 will complete | finish an error alerting | reporting, if an error cancellation signal is input.

  Then, the main CPU 71a clears the setting of the invalid flag F3 (step S247) and ends the game restart process. As a result, the main CPU 71a receives the start opening winning detection signal and the big winning opening winning detection signal when the start opening winning detection signal and the big winning opening winning detection signal are output from the starting opening sensor SE1 and the big winning opening sensor SE2. To come.

As described above in detail, this embodiment has the following effects in addition to the effects (4), (7), and (8) to (11) of the first embodiment.
(13) When the main CPU 71a determines that it is illegally released, the main CPU 71a sets the invalid flag F3 to invalidate the input of the start port winning detection signal and the big winning port detection signal. Thereby, the symbol combination game is not started or the game ball is not paid out after the invalid flag F3 is set, that is, based on the winning of the game ball after the main CPU 71a determines that it is illegally released. For this reason, after the unauthorized opening, the amusement shop side will not be damaged.

(Fourth embodiment)
Next, a fourth embodiment embodying the present invention will be described. In addition, the same code | symbol as 1st embodiment is attached | subjected to the structure similar to 1st embodiment, the detailed description and drawing are abbreviate | omitted or simplified.

  In the fourth embodiment, the big prize opening door 57 is provided with a big prize opening door detection sensor (not shown) that detects the opening of the big prize opening door 57. The big winning opening door opening detection sensor outputs a big winning opening door opening signal to the main CPU 71a when the opening of the big winning opening door 57 is detected.

  Then, the main CPU 71a determines whether or not the big winning opening door 57 is opened in a normal order based on the order of the big winning opening door opening signal input from the big winning opening door opening detection sensor and the occurrence timing of the big hit. If the game is released in an unauthorized order, it is regarded as an unauthorized release (unauthorized act) so that the game ball is not paid out. This will be described in detail below.

The main CPU 71a executes a special winning opening unauthorized opening prevention process (FIG. 26) every predetermined period.
First, the main CPU 71a determines whether or not a big hit game has occurred (for example, whether or not a big hit has occurred in step S331). If this determination result is affirmative, the main CPU 71a sets “1” to a big hit flag F4 indicating whether or not a big hit has occurred (step S332).

  When the process of step S331 or step S332 is completed, the main CPU 71a determines whether or not a big winning opening door opening signal is input from the big winning opening door opening detection sensor (step S333). If the result of this determination is negative, the special winning opening illegal opening prevention process is terminated.

  On the other hand, if the determination result of step S333 is affirmative, the main CPU 71a determines whether or not “1” is set in the big hit flag F4. If the determination result is affirmative, the main CPU 71a determines that the special prize opening door 57 has been opened illegally (i.e., has been opened illegally), and sends an error signal indicating that an illegal act has occurred to the overall control board 72 and the payout. The data is output to the control board 76 (step S335). Hereinafter, the processing from step S335 to step S337 is the same as the processing from step S35 to step S37 of the first embodiment, and thus detailed description thereof is omitted.

As described above in detail, this embodiment has the following effects in addition to the effects (1) to (11) of the first embodiment.
(14) After the symbol combination game is a big hit and a big hit game, the big prize opening door 57 is opened in a normal game flow. For this reason, it can be regarded that there was an illegal act that the big prize door 57 is opened even though it is not a big hit. Therefore, in the present embodiment, a big winning opening door opening detection sensor is provided, and it is illegal depending on the order of input of the big winning opening door opening signal from the big winning opening door opening detection sensor and the time when the big hit determination is a big hit. It was determined whether or not it was open. When the main CPU 71a determines that it is illegally released, the main CPU 71a outputs an error signal to the payout control board 76 to instruct to stop paying out the game balls. As a result, the game balls are not paid out. Therefore, even if the big prize opening door 57 is opened and the game balls are won in the big prize opening 58, illegal game balls can be prevented from being paid out. Therefore, since it becomes impossible to obtain a game ball by an illegal act, the game store side is not damaged and can prevent fraud.

In addition, the said embodiment can be embodied in another embodiment (another example) as follows.
In the above embodiment, when the main CPU 71a determines that it is illegally released, the main CPU 71a outputs an error signal to the display control board 73, the lamp control board 74, and the voice control board 75 via the overall control board 72 to notify the error. The error notification may be executed by at least one of the display control board 73, the lamp control board 74, and the sound control board 75.

  In the above embodiment, the main CPU 71a outputs an error release signal when the main CPU 71a determines that it is normally opened. However, only a person at the amusement shop can operate a switch that can output the error release signal. You may provide in such a position.

In the first embodiment and the second embodiment, the payout control board 76 stops the launch of the game ball, but it does not have to be stopped.
In the above embodiment, the housing recess 12e is closed by the cover member 32 separate from the front frame 13, but the housing recess 12e may be closed by the front frame 13.

In the above embodiment, the upper tray 16 is integrally formed with the front frame 13, but may be formed separately.
The door opening detection switch 41 of the above embodiment detects the opening of the front frame 13 and the middle frame 12, but detects the opening of the front frame 13 and the opening of the middle frame 12 to detect the opening of the front frame 13. A middle frame opening detection switch may be provided separately. In this case, the main CPU 71a inputs opening signals from the front frame opening detection switch and the middle frame opening detection switch, respectively.

In the above embodiment, the locking device 20 is provided with the opening restriction mechanism K, but it may not be provided. Moreover, although the locking control member 37 is provided in the locking device 20, it does not need to be provided.
In the fourth embodiment, it is determined whether or not the special winning opening door 57 is opened in a normal order, but it may be determined whether or not other doors are normally opened. For example, a sensor for detecting the opening of the opening / closing blade 55 is provided, and the condition for opening the opening / closing blade 55 is not satisfied (the normal symbol combination game using a normal symbol different from the symbol used in the symbol combination game is a hit. However, it may be determined whether the opening / closing blade 55 is opened or closed.

  In the above-described embodiment, the pachinko machine 10 is used as a specific example. However, the present invention may be realized using a spinning-type game machine (so-called slot machine) that uses a medal as a game medium, a pachinko slot machine, or the like.

  In the first embodiment, when the restriction flag F2 is set to “1”, the main CPU 71a does not change the value even if a value of “1” or more is stored in the start opening winning number or the large winning opening winning number. Although the 1 payout instruction command and the second payout instruction command are not output, they may be output. Specifically, the main CPU 71a outputs a first payout instruction command to the payout control board 76 when the start opening prize number is 1 or more in the output process, and every time the main CPU 71a outputs the first payout instruction command, 1 is output from the start opening prize number. You may subtract. Further, in the output process, the main CPU 71a outputs a second payout instruction command to the payout control board 76 when the number of winning a prize opening is 1 or more, and subtracts 1 from the number of winning a prize opening every time it is output. May be. In this case, when the sub CPU 76a of the payout control board 76 inputs the first payout instruction command, the sub CPU 76a adds the predetermined number instructed by the first payout instruction command to the payout remaining number indicating the payout remaining number of prize balls. It is necessary to store in the RAM 76c. Similarly, when the sub CPU 76a of the payout control board 76 inputs the second payout instruction command, the sub CPU 76a adds the predetermined number instructed by the second payout instruction command to the payout remaining number, and enters the RAM 76c provided in the payout control board 76. I need to remember.

  In the above embodiment, it is determined whether or not the front frame 13 or the middle frame 12 has been opened in a normal order. However, if it is determined that another predetermined abnormal state has occurred, the restriction flag F2 or An invalid flag F3 may be set. The abnormal state refers to, for example, a state in which the upper receiving tray 16 and the lower receiving tray 17 are full of game balls and cannot be paid out, or a state in which the game balls are supported by the game nails and the game balls no longer flow. In this case, it is necessary to provide a sensor (such as a full sensor) for detecting an abnormal state and notify the main CPU 71a of the abnormal state.

  The unlock detection sensor 40 of the above embodiment detects the movement of the protrusion 29b, but may detect the movement of the protrusion 29a. Further, two or more unlock detection sensors 40 may be provided to detect in which direction the cam 29 is rotated (that is, which of the front frame 13 or the middle frame 12 is opened). The unlock detection sensor 40 of the present embodiment detects that the cylinder lock 28 is not unlocked when the emitted light is shielded, and if the light is not shielded, it indicates that the cylinder lock 28 is unlocked. Detected. As another example, an unlock detection sensor 40 is provided for detecting that the cylinder lock 28 is unlocked when the emitted light is shielded, and detecting that the cylinder lock 28 is not unlocked when the light is not shielded. May be. In this case, it is necessary to provide the cam 29 with a light shielding plate that shields the light emitted from the unlock detection sensor 40 while the cylinder lock 28 rotates.

  In the above embodiment, the payout control board 76 pays out the game balls one by one by exciting (ON) or demagnetizing (OFF) the payout solenoid 77l. For example, the payout control board 76 degausses the payout solenoid 77l until the payout remaining number becomes 7, and once the payout remaining number becomes 7, it is excited to stop payout of the game ball. Thereafter, the degaussing is again performed until the payout remaining number becomes 2, and when the payout remaining number becomes 2, the magnet is temporarily excited to stop the payout of the game ball. Thereafter, the game balls may be paid out one by one. In this way, game balls can be quickly paid out. Further, when the remaining payout amount is reduced, one ball (or several balls) is paid out one by one, so that extra game balls are not paid out. Even when game balls are paid out in this way, the payout control board 76 immediately stops paying out game balls when an error signal is input.

In the fourth embodiment, the fraud prevention process (FIG. 22) is executed together with the prize winning door unauthorized opening process (FIG. 26), but only the prize winning door unauthorized opening process may be executed.
