Abstract

<P>PROBLEM TO BE SOLVED: To provide a game machine which can definitely prevent unjust alteration of the winning probability. <P>SOLUTION: The sub base board the sub CPU (central processing unit) has the judgement section and the sub RAM (random access memory). The main CPU sends the alteration signal to the sub CPU in response that the setting change is made. The judgement section judges if the time when the alteration signal was sent falls within the alteration allowable time range memorized in the sub RAM. If it judges that the time does not fall within the alteration allowable time range, the judgement section memorizes the error information in the sub RAM (error flag is in the state of ON). When the start lever is operated the main sub CPU sends the operation signal to the sub CPU. Sub CPU then, in response to the inputted operation signal, judges if the error flag is in the state of ON or not. When the error flag is judged in the state of ON, the sub CPU controls the error code display device, lamp and the driving of the speaker and makes the error information announced that the foul play is done. <P>COPYRIGHT: (C)2007,JPO&INPIT

  As shown in FIG. 4, the operation of the slot machine 10 is basically controlled by the main board 37 and the sub board 38. In addition to the main CPU 37a and the main ROM 37b, the main board 37 is provided with an electronic lottery unit 37c and a winning combination determining unit 37d. The main ROM 37b stores a control program such as a game execution program executed by the main CPU 37a, control data necessary for executing these programs, and the like.

  The main ROM 37b stores first to sixth winning tables 41 to 46 and a setting change program 47. The first to sixth winning tables 41 to 46 are provided such that the winning probabilities for the loser and the plurality of types of winning combinations are different from each other, and the selected winning table has a medal payout probability (payout rate) in the game. Will be different. In this embodiment, the winning table with the lowest payout rate is the first winning table 41, the winning table with the highest payout rate is the sixth winning table 46, and when the set value is “1”, the first winning table is given. When the table 41 is selected and the set value is “6”, the sixth winning table 46 is selected. Further, the main CPU 37a inputs a change signal to the sub CPU 38a of the sub board 38 in response to the start of the setting change program 47. The first to sixth winning tables 41 to 46 may be provided with different winning probabilities for at least any one of a plurality of types of winning combinations, and the number of winning combinations provided with different winning probabilities. Are appropriately changed. Thereby, by the operation of the key cylinder 32 and the setting change button 33, at least one of the plurality of types of winning combinations is changed. Further, the first to sixth winning tables 41 to 46 and the setting change program 47 may be stored in the winning combination determining unit 37d.

  In the present embodiment, when the administrator of the game hall where the slot machine 10 is installed changes the setting value of the slot machine 10, first, the setting key 36 is inserted into the key hole 32 c of the key cylinder 32, and the rotation unit After rotating 32b to the ON position (see FIG. 10), when the power switch 29 is operated to turn on the main power of the slot machine 10, the setting change program 47 is activated, and the setting change button 33 is operated in this state. By doing so, the setting value is changed. When the setting change button 33 is operated, a change execution signal is input to the main CPU 37a. The main CPU 37a changes the winning table to be selected each time a change execution signal is input. For example, when the setting value before change is “3” and the setting value is changed to “6”, the setting change button 33 is operated three times. As a result, the set value is changed in order of “3 → 4 → 5 → 6”, and the set value becomes “6” after three operations. Then, after rotating the rotating portion 32b to a position where it is turned off (see FIG. 6), the setting key 36 is removed from the key hole 32c, and the start lever 20 is operated, the setting value “6” is confirmed. In the present embodiment, the main CPU 37a also functions as a probability changing unit that changes the winning probability of at least one of the loser and the multiple types of winning combinations.

  The setting key 36 is inserted into the key hole 32c of the key cylinder 32, and after the rotating portion 32b is rotated to the ON position (see FIG. 10), the power switch 29 is operated to turn on the main power of the slot machine 10. Then, the set value is displayed on the credit number display device 13. Thereby, the administrator of the game hall can change the set value while confirming the set value. Further, after rotating the rotating portion 32b to the off position (see FIG. 6), the setting key 36 is removed from the key hole 32c and the set value is confirmed by operating the start lever 20, the credit number display device 13 is displayed. The displayed set value is hidden.

  The main CPU 37a outputs a setting change signal (change signal) to the sub CPU 38a of the sub board 38 in response to the start of the setting change program 47. In the present embodiment, the main CPU 37a also functions as a signal output unit that outputs a setting change signal (change signal) to the sub-board 38 when the setting is changed.

  The sub-board 38 determines whether or not the time when the setting change signal (change signal) is input is within a preset changeable time (for example, 23:00 to 10:00). The determination unit (error determination unit) 38b is provided, and the determination unit 38b is provided with a sub RAM 38c. The sub RAM 38c stores time data of the changeable time described above. The determination unit 38b is provided with a timer, measures the time when the setting change signal is input, and determines whether this time is within the changeable time stored in the sub RAM 38c. Here, when it is determined that the time is not within the changeable time, the determination unit 38b stores error information in the sub RAM 38c. In the present embodiment, this state is described as an error flag ON state.

  On the other hand, when the determination unit 38b determines that the time when the setting change signal is input is within the changeable time, the determination unit 38b erases the error information in the sub RAM 38c. That is, the error flag is turned off.

  The medal sensor 51 detects an appropriate medal inserted from the medal slot 23 and inputs it to the main CPU 37a. A selector is incorporated in the back of the medal insertion slot 23, and an inappropriate medal is discharged to the medal tray 29. In addition, when a selector inserts a medal at an inappropriate timing, for example, a medal inserted in the middle of a game or while various operation buttons are pressed without passing through the medal sensor 51. It is discharged to the medal tray 29.

  Since the number of medals inserted prior to the start of the game is limited to 1 to 3, the medal sensor 51 also detects medals inserted after the fourth one when the credit function is not used. Without being discharged to the medal tray 29. The credit function is turned on / off every time the payout button is pushed. When the credit function is on, medals inserted after the fourth sheet are also detected by the medal sensor 51 and credited to the inside of the slot machine up to 50 sheets.

  The number of credited medals is digitally displayed on the credit number display device 13. When the credit function is used, a medal insertion operation is performed by operating the single bet button 17 or the MAX bet button 18, and the bet number is sequentially subtracted from the credit number. Further, when a game is performed and a winning with a medal payout is obtained, the payout medal is also credited, and the medal credited when the payout button is operated is paid out to the medal tray 29.

  The main CPU 37a counts the number of 1 to 3 medals inserted prior to the start of the game based on the detection signal from the medal sensor 51, and determines the number to activate the winning effective line. The number of credits is counted by another credit medal counter (not shown).

  The start signal sensor 52 inputs a game start signal indicating that the start lever 20 is operated to the main CPU 37a when the start lever 20 is operated after 1 to 3 medals are inserted. In response to the game start signal, the main CPU 37a rotates the first to third reels 11a to 11c based on a program for executing a game stored in the main ROM 37b and starts a game process.

  The drive and stop control of the first to third reels 11 a to 11 c are performed by the main CPU 37 a and the reel drive controller 53. Each reel is attached to a drive shaft of an individual stepping motor 55a to 55c, and each reel is controlled by controlling the driving of each stepping motor 55a to 55c. The RAM area of the main ROM 37b is used for temporary storage or rewriting of flags and data used for each game.

  The stepping motors 55a to 55c rotate at a rotation angle corresponding to the number of drive pulses supplied from the main CPU 37a. Therefore, the rotation angles of the first to third reels 11a to 11c and the sub reel 16 can be controlled by controlling the number of drive pulses supplied from the main CPU 37a, and the reels can be stopped by stopping the supply of drive pulses. The position can be determined. Each reel is integrally formed with reflection signal portions 56a to 56c at its reference position, and the photosensors 57a to 57c photoelectrically detect the passage of each reflection signal portion for each rotation. Detection signals from the photosensors 57a to 57c are input to the main CPU 37a as a reset signal indicating the reel reference position.

  The main CPU 37a is provided with a pulse counter that counts the number of drive pulses supplied to the respective stepping motors 55a to 55c. When the main CPU 37a receives a reset signal from the photosensors 57a to 57c, Clear the count value of the corresponding pulse counter. Therefore, the number of drive pulses corresponding to the rotation angle within one rotation of each reel is stored in each pulse counter while being sequentially updated.

  In the ROM area of the main ROM 37b, there is a symbol table in which the number of drive pulses corresponding to the rotation angle from the reference position of each reel is associated with symbol codes representing symbols arranged on the reel at a constant pitch. Stored. The main CPU 37a monitors the count value of the pulse counter for each reel while referring to this symbol table to identify which symbol has moved on, for example, the middle winning pay line, and which If the reel is rotated to some extent, it can be predicted whether the target symbol will move on the winning line.

  When the stop buttons 21a to 21c are operated, the stop button sensors 58a to 58c input a stop signal indicating that the stop buttons 21a to 21c are operated to the main CPU 37a. When the start lever 20 is operated and rotation of the first to third reels 11a to 11c starts and the rotation reaches a steady speed, the main CPU 37a validates the operation of the stop buttons 21a to 21c. Thereafter, when the stop buttons 21a to 21c are operated, stop control of the first to third reels 11a to 11c corresponding to the stop buttons 21a to 21c is started.

  The main CPU 37a operates the electronic lottery section 37c in response to the game start signal sent from the start signal sensor 52. The electronic lottery unit 37c includes a random number generator and a random number sampling circuit, and draws one random value every time a game is started. The random value selected by lottery is input to the winning combination determining unit 37d. In the winning combination determination unit 37d, it is determined according to the input value what type of winning combination is awarded in the currently executed game.

  The winning combination determination unit 37d described above in the first to sixth winning tables 41 to 46 of the main ROM 37b determines whether the random value lottery by the electronic lottery unit 37c is lost or a plurality of types of winning combinations. The decision is made with reference to the winning table selected by the set value. In addition to the first to sixth winning tables 41 to 46 for the normal mode, the main ROM 37b is provided with a winning table used for games in the BB mode, games in the RB mode, and the like. In the RB mode, the winning combination determination unit 37d refers to the corresponding winning table to make a winning determination.

  The hopper device 26b pays out a prescribed number of payout medals to the medal tray 29 according to the type of winning combination. The payout table in which the number of payout medals is determined for each type of winning combination is stored in the main ROM 37b, and the main CPU 37a reads this to drive the hopper device 26b.

  Next, the operation of the slot machine 2 configured as described above will be described using the flowchart of FIG. When changing the setting value of the slot machine 10, the setting key 36 is inserted into the key hole 32 c of the key cylinder 32, and the rotating unit 32 b is rotated to a position where it is turned on (see FIG. 3B). When the main power supply of the slot machine 10 is turned on by operating the switch 29, the setting value is displayed on the credit number display device 13, and the setting change program 47 is activated, and the setting value can be changed. Next, the setting change button 33 is operated to change the setting value (step (hereinafter, S) 1). For example, when the setting value before change is “3” and the setting value is changed to “6”, if the setting change button 33 is operated three times, the setting value becomes “3 → 4 → 5 → 6”. It is changed in order, and the set value becomes “6” after three operations. At this time, the manager of the game hall can change the setting value while checking the setting value displayed on the credit number display device 13.

  After changing the set value from “3” to “6”, the rotating portion 32b is rotated to a position where it is turned off (see FIG. 3A), the setting key 36 is removed from the key hole 32c, and the start lever 20 is released. When the operation is performed, the set value “6” is confirmed, and the set value displayed on the credit number display device 13 is not displayed. As a result, the sixth winning table 46 corresponding to the set value “6” is selected, and the lottery probability for the loss and the multiple types of winning combinations is determined from the lottery probabilities of the third winning table 43 corresponding to the set value “3”. That is, the lottery probability of the sixth winning table 46 corresponding to the set value “6” is changed.

  In response to the activation of the setting change program 47, the main CPU (signal output unit) 37a of the main board 37 inputs a setting change signal to the sub CPU 38a of the sub board 38 (S2). The sub CPU 38a outputs the input setting change signal (change signal) to the determination unit 38b. The determination unit 38b measures the time when the setting change signal is input by a timer, and determines whether or not this time is within the changeable time (23:00 to 10:00) stored in the sub RAM 38c. Determine (S3). Here, when it is determined that the time is not within the changeable time (for example, 15:00), the determination unit 38b stores error information in the sub RAM 38c. That is, the error flag is turned on (S4).

  When the start lever (operation device) 20 is operated after 1 to 3 medals are inserted, the start signal sensor 52 outputs a game start signal indicating that the start lever 20 has been operated to the main CPU 37a. . In response to the game start signal, the main CPU 37a rotates the first to third reels 11a to 11c based on the program for executing the game stored in the main ROM 37b to start the game process and to the sub CPU 38a. Outputs an operation signal. In response to the input of the operation signal (S5), the sub CPU 38a determines whether or not the error flag is ON (S6). Here, if it is determined that the error flag is in the ON state, the sub CPU 38a controls the drive of the error code display device 15, the lamp 24, and the speaker 25 to indicate that an illegal act has been performed on them. Notification is performed (S7).

  In order to cancel the error notification by the error code display device 15, the lamp 24, and the speaker 25, the error notification cancel button 35 is operated (S8). When the error notification cancel button 35 is operated, the error notification is canceled (S9). At this time, the error notification is canceled, but the error flag ON state is not canceled. Therefore, when the start lever 20 is operated again, when the operation signal is input (S5), the error notification is performed again (S7). .

  On the other hand, when the determination unit 38b determines that the time when the setting change signal is input is within the changeable time (for example, 9:30), the determination unit 38b erases the error information in the sub RAM 38c. To do. That is, the error flag is turned off (S10). Then, in response to the input of the operation signal (S5), the sub CPU 38a determines whether or not the error flag is ON (S6). In this case, it is determined that the error flag is not in the ON state (error flag OFF state), and the sub CPU 38a does not perform the error notification as described above, and the slot machine 2 enters the normal gaming state (S11). .

  As described above, when the setting is changed in the slot machine 2 during a time that is not within the changeable time (23:00 to 10:00), the determination unit 38b of the sub board 38 sends error information to the sub CPU 38a. In response to the operation of the start lever 20 and the input of the operation signal from the main CPU 37a, the sub CPU 38a controls the drive of the error code display device 15, the lamp 24, and the speaker 25, and illegally controls them. Since the error notification that the act has been performed is performed, the changeable time is set to a time outside the business hours (for example, 10:00:00 to 23:00) of the amusement hall where the slot machine 2 is installed (23:00:00) 10:00), when an unauthorized person who intends to change the setting illegally changes the setting during business hours, the start lever 20 is operated. After, because an error notification is performed, this error notification, game arcade manager can be quickly perceive that fraud has been performed.

  Further, even when the error notification cancellation button 35 is operated and the error notification is canceled, the error flag ON state is not canceled. Therefore, when the start lever 20 is operated again, the error notification is performed again. The error error notification release button 35 must be operated for each game, and this action suppresses illegal actions such as illegally changing settings in order to attract the attention of surrounding players and game hall managers. can do.

  Further, when the determination unit 38b determines that the time when the setting change signal is input is within the changeable time, the determination unit 38b erases the error information in the sub-RAM 38c. When the slot machine 2 in the flag ON state is brought into an error flag OFF state in which a normal game can be performed, it can be easily performed only by changing the setting again within the changeable time.

  Furthermore, since the changeable time stored in the sub-RAM 38c of the sub-board 38 can be changed by the time change button 34, it can be changed when the game hall manager changes the setting during business hours. By changing the time, the error flag can be turned off so that a normal game can be performed without making an error notification even after the setting is changed.

  Further, since the changeable time stored in the sub RAM 38c of the sub board 38 can be changed by the time change button 34, the slot machine 2 embodying the present invention is installed in a plurality of game halls having different business hours. be able to.

  In the above embodiment, the main CPU 37a outputs an operation signal to the sub CPU 38a in response to the operation of the start lever 20, but the main CPU 37a does not limit the operation signal to the sub CPU 38a. For example, when a medal is inserted, when the stop buttons 21a to 21c are operated, when a medal is paid out, when the settlement button 19 is operated, or when BB starts, It can be changed as appropriate when a game is played on the BB (for example, when the BB20 game ends) or when the BB ends.

  In the above-described embodiment, the sub CPU 38a controls the drive of the error code display device 15, the lamp 24, and the speaker 25 so as to notify them that an illegal act has been performed. The error notification may be performed by at least one of the three notification devices, and the number of notification devices that perform the error notification can be changed as appropriate. Furthermore, the notification device that performs error notification may be any device as long as the drive is controlled by the sub CPU 38a, and can be changed as appropriate.

  In the above embodiment, the slot machine 2 has been described as an example. However, the present invention can also be applied to various gaming machines such as a pachinko machine.
