FIG. 15 is a flowchart showing the processing of the CPU 200 of the main control board 20 when displaying the lottery probability of winning combination on the numerical information display unit 400 and when prohibiting the display.

  In FIG. 15, the CPU 200 (see FIG. 3) of the main control board 20 (see FIG. 3) performs processing to determine whether or not to display the winning lottery probability setting on the numerical information display unit 400 (see FIG. 1). In this case, first, in step S1, it is determined from the output of the photosensor 311 (see FIGS. 3 and 5) whether the front door cylinder lock 78 has been unlocked. If the photosensor 311 does not indicate that the detection result has detected the cam plate 309 (see FIG. 5), the determination in step S1 is NO and the CPU 200 proceeds to the process in step S2. When the photosensor 311 outputs a detection signal indicating that the detection result has detected the cam plate 309, the determination in step S1 is YES, and the CPU 200 proceeds to the process in step S3.

  In step S2, the CPU 200 detects whether or not the front door opening detection switch 85 is in an on state. Here, the front door 3 (see FIG. 2) is closed with respect to the housing 2 (see FIG. 2), and the pressing portion 712 (see FIG. 10) is pressed by the support plate portion 331 (see FIGS. 4 and 10). In this state, the determination in step S2 is NO, and the CPU 200 returns to the process in step S1. Further, when the front door 3 is opened with respect to the housing 2 and the support plate portion 331 is separated from the pressing portion 712, the determination in step S2 is YES, and the CPU 200 proceeds to the processing in step S10.

  In step S10, the CPU 200 performs control to output an alarm to the effect device 230 via the sub-control board 30, outputs an abnormality occurrence signal to the external concentrated terminal board 25 (see FIG. 2), and produces an effect sound emission. By causing the speakers 32a, 32b, 38a, 38b (see FIG. 2) of the unit 62 (see FIG. 1) to issue an alarm and prohibiting the reception of the setting key rotation signal (see FIG. 14), the numerical information display unit 400 The state where the number of medals won by winning is displayed and the process ends.

  On the other hand, in step S3, the CPU 200 detects whether or not the front door opening detection switch 85 is on. Here, when the front door 3 is closed with respect to the housing 2, the determination in step S3 is NO, and the CPU 200 proceeds to the process in step S4. Further, when the front door 3 is opened with respect to the housing 2 and the support plate portion 331 is separated from the pressing portion 712, the determination in step S3 is YES, and the CPU 200 proceeds to the processing in step S5.

  In step S4, the CPU 200 determines whether or not the setting key rotation signal has been received by performing the detection process of the setting key rotation signal (see FIG. 14) with respect to the addition output a3 (see FIG. 14). Here, in a state where the setting lock 83 is not operated, the determination in step S4 is NO, and the CPU 200 returns to the process in step S3. When the operator inserts the setting key 800 into the key hole 836 of the setting lock 83 and rotates the setting key 800 clockwise, the addition output a3 is in the state of the period A → B → C, and the CPU 200 A key rotation signal is accepted, the determination in step S4 is YES, and the process proceeds to step S10.

  In step S5, the CPU 200 counts the period A from when the output a0 from the photo sensor 91 rises from the low level L to the high level H until the addition output a3 falls from the high level H to the low level L, The period B from when the added output a3 falls from the high level H to the low level L to when it rises to the middle level M that is ½ of the high level H is counted, and the process proceeds to step S6.

  In step S6, the CPU 200 determines whether a setting key rotation signal has been received based on the addition output a3. Here, in a state where the addition output a3 is not operated until the period C during which the low level L rises to the middle level M, the determination in step S6 is NO, and the CPU 200 repeats the process in step S6. When the operator inserts the setting key 800 into the key hole 836 of the setting lock 83 and rotates the setting key 800 clockwise, the addition output a3 is in a state of period A → B → C, and the CPU 200 rotates the setting key. The signal is accepted, the determination in step S6 is YES, and the process proceeds to step S7.

  In step S7, the CPU 200 determines whether or not both the period A and the period B counted in step S5 are within the first and second predetermined times. When both the period A and the period B counted in step S5 are within the first and second predetermined times, the CPU 200 makes a determination of step S7 to make a normal operation with respect to the set lock 83. If the period A exceeds the first predetermined time or the period B exceeds the second predetermined time, the determination at step S7 is made. NO is determined, and it is determined that an illegal operation has been performed, and the process proceeds to step S10.

  In step S <b> 8, the CPU 200 controls the numerical information display unit 400 to display numerically the numbers 1 to 6 for the winning combination lottery probability and ends the process.

Here, consider the case where the setting display is performed by opening the front door 3 with respect to the housing 2 and inserting the setting key 800 into the key hole 836 of the setting lock 83 in a regular operation.
In this case, the operator performs an unlocking operation on the front door cylinder lock 78 using the front door key 600 and then opens the front door 3 with respect to the housing 2 to open the front door opening detection switch 85. When the setting key 800 is inserted into the key hole 836 of the setting lock 83 and the setting change permission operation is performed, the CPU 200 performs the process from step S1 → S3 → S5 → S6 → S7 → S8. Thus, the setting of the lottery probability of the winning combination is numerically displayed with numbers from 1 to 6 on the numerical information display unit 400.

  Next, a fraudulent person inserts a fraudulent instrument through the gap between the closed front door 3 and the housing 2 without performing an unlocking operation on the front door cylinder lock 78, and hooks 303, When the latching of the receiving brackets 26 and 27 by 304 is forcibly released and the front door 3 is opened, the CPU 200 performs the process of steps S1 → S2 → S10.

It is reset when it is detected from the output of the front door opening detection switch 85 (see FIG. 10) that the door 3 is closed from the opened state. If the unlock flag has not been set, the determination in step S12 is NO, and the CPU 200 proceeds to the process in step S13. If the unlock flag is set, the determination in step S12 is YES, and the process proceeds to step S15.

  In step S13, the CPU 200 detects whether or not the front door opening detection switch 85 is on. Here, in a state where the front door 3 is opened with respect to the housing 2 and the support plate portion 331 (see FIG. 10) is separated from the pressing portion 712 (see FIG. 10), the determination in step S13 becomes YES, and the CPU 200 The process proceeds to step S30. When the front door 3 is closed with respect to the housing 2, the determination in step S13 is NO, and the CPU 200 proceeds to the process in step S14.

  In step S30, the CPU 200 determines whether or not the power switch 81 of the main power supply device 23 is turned on. If the power switch 81 is not turned on, the determination in step S30 is NO, and the CPU 200 repeats the process in step S30. Then, when the power switch 81 is turned on, the CPU 200 determines YES in step S30, and proceeds to the process in step S31 shown in FIG.

  In step S31, the CPU 200 performs control to output an alarm to the effect device 230 via the sub-control board 30, outputs an abnormality occurrence signal to the external concentrated terminal board 25 (see FIG. 2), and produces an effect sound emission. Processing is performed by causing the speakers 32a, 32b, 38a, 38b (see FIG. 2) of the unit 62 (see FIG. 1) to issue an alarm and prohibiting the reception of the setting change operation signal by operating the setting change button 86 (see FIG. 2).

When the operator inserts the setting key 800 (see FIG. 12) into the key hole 836 (see FIG. 12) of the setting lock 83 (see FIG. 12) and rotates the setting key 800 clockwise, the CPU 200 rotates the setting key. The signal is accepted, the determination in step S14 is YES, and the process proceeds to step S30.

  In step S15, the CPU 200 detects whether or not the front door opening detection switch 85 is on. Here, when the front door 3 is closed with respect to the housing 2, the determination in step S15 is NO, and the CPU 200 proceeds to the process in step S14. Further, when the front door 3 is opened with respect to the housing 2 and the support plate portion 331 is separated from the pressing portion 712, the determination in step S15 is YES, and the CPU 200 proceeds to the processing in step S16.

  In step S <b> 16, the CPU 200 indicates the output a <b> 0 from the photo sensor 91. The period from when the set key rotation signal of the addition output a <b> 3 falls from the high level H to the low level L after the rise from the low level L to the high level H A is counted, and a period B from when the set key rotation signal of the addition output a3 falls from the high level H to the low level L until it rises to the middle level M that is 1/2 of the high level H is counted. Transition to processing.

  In step S <b> 17, the CPU 200 determines whether or not the setting key rotation signal has been received by performing a detection process of the setting key rotation signal (see FIG. 14) with respect to the addition output a <b> 3 (see FIG. 14). Here, the CPU 200 determines NO in step S17 until the period C in which the set key rotation signal of the addition output a3 rises from the low level L to the middle level M, and repeats the process of step S17. When the operator inserts the setting key 800 into the key hole 836 of the setting lock 83 and rotates the setting key 800 clockwise, the CPU 200 accepts the setting key rotation signal, the determination in step S17 becomes YES, and in step S18 Transition to processing.

  In step S18, the CPU 200 determines whether or not both the period A and the period B counted in step S16 are within the first and second predetermined times. When both the period A and the period B counted in step S16 are within the first and second predetermined times, the CPU 200 makes a determination of step S18 to perform a normal operation on the set lock 83. If the period A exceeds the first predetermined time or the period B exceeds the second predetermined time, the determination at step S18 is made. NO is determined, and it is determined that an illegal operation has been performed, and the process proceeds to step S31.

  In step S <b> 19, the CPU 200 determines whether or not the power switch 81 is turned on on the front surface of the main power supply device 23. Here, when the power switch 81 is not turned on, the CPU 200 determines NO in step S10 and repeats the process in step S19. Then, when the power switch 81 is turned on, the CPU 200 determines YES in step S19, and proceeds to the process in step S20 shown in FIG.

  In step S20, the CPU 200 performs control to display a numerical value on the numerical information display unit 400 with numbers from 1 to 6 using the setting of the lottery probability of the winning combination currently set as a setting candidate value, and proceeds to the processing of step S21.

  In step S21, the CPU 200 detects whether or not the setting change button 86 has been turned on. If the setting change button 86 is turned on, the determination in step S21 is YES, and the CPU 200 proceeds to the process in step S22. If the setting change button 86 is not turned on, the determination in step S22 is NO, and the CPU 200 proceeds to the process in step S23.

  In step S22, the CPU 200 changes the setting candidate value displayed on the numerical information display unit 400 once, and proceeds to the process of step S23. Here, the method of changing the setting candidate value once is that when the setting candidate value before the change is 1 to 5, the setting candidate value before the change is set to 6 by counting up the number 1 to obtain the setting candidate value after the change. In this case, 1 is the setting candidate value after the change.

  In step S23, the CPU 200 detects whether the lever 75 is turned on. If the lever 75 is not turned on, the determination in step S23 is NO, and the CPU 200 returns to the process of step S21. If the lever 75 is turned on, the process proceeds to step S23. The determination is YES, and the CPU 200 proceeds to the process of step S24.

  In step S24, the CPU 200 changes the setting candidate value displayed on the numerical information display unit 400 as an actual setting value and replaces the original setting value with the original setting value to store the setting value in the storage unit 201. .

Here, consider a case where the setting is changed by opening the front door 3 with respect to the housing 2 and inserting the setting key 800 into the key hole 836 of the setting lock 83 in a regular operation.

The lottery probability setting is changed normally. Thereafter, the setting key 800 inserted into the setting lock 83 is turned counterclockwise so that the width direction of the setting key 800 is turned off, the setting key 800 is pulled out from the setting lock 83, the power switch 81 is turned on, and then the housing is turned on. The slot machine 1 can be played by closing the front door 3 with respect to the body 2.

  On the other hand, an unauthorized person inserts an unauthorized instrument through the gap between the closed front door 3 and the housing 2 without performing an unlocking operation on the front door cylinder lock 78, and the movable hook 303, When the latching of the metal fittings 26 and 27 by 304 is forcibly released and the front door 3 is opened, the CPU 200 performs the process in steps S11 → S12 → S13 → S30 → S31. 230 is controlled to output an alarm, an abnormality occurrence signal is output to the external concentrated terminal board 25 (see FIG. 2), and the speakers 32a, 32b, 38a, and 38b of the effect sound emitting unit 62 (see FIG. 1) are output. (See FIG. 2), the alarm is uttered, and the state where the number of medals obtained by winning is displayed on the numerical information display unit 400 is maintained.

  Next, an unauthorized person inserts a fraudulent instrument through the gap between the closed front door 3 and the housing 2, and the power switch 81 of the main power supply device 23 is turned on without opening the front door 3. When the unauthorized device is inserted into the main power supply device 23 and the unauthorized device is inserted and inserted into the key hole 836 of the setting lock 83 and the setting candidate value is displayed, the CPU 200 performs the processing in steps S11 → S12 → S13 → The flow is S14 → S31 or steps S11 → S12 → S15 → S14 → S31. In step S31, processing corresponding to an abnormality such as outputting an alarm to the effect device 230 is performed.

  It should be noted that the process of the CPU 200 is in the sequence of steps S11 → S12 → S13 → S14 → S31 when an illegal act is performed without performing an unlocking operation on the front door cylinder lock 78. The process of the CPU 200 is the flow of steps S11 → S12 → S15 → S14 → S31 because the unlocking operation is performed on the front door cylinder lock 78, but the front door 3 is not opened, and an illegal act is performed. This is the case.

  In addition, a person who performs fraud performs an unlocking operation with respect to the front door cylinder lock 78 using a forged front door key, and then opens the front door 3 with respect to the housing 2 to open the front door. When the detection switch 85 is turned on, and then the unauthorized device is inserted into the key hole 836 of the setting lock 83 to perform the unlocking operation of the setting lock 83, the CPU 200 performs processing in steps S11 → S12 → S15 → S16 → S17 → S18 → S31, and in step S31, processing corresponding to an abnormality such as outputting an alarm to the rendering device 230 is performed.

And a time when the detection result of the setting key operation detection switch 92 is within the second rotation range, and whether or not these detection times are within a predetermined time. The CPU 200 determines that a setting change permission operation is performed on the setting key 800 only when the detection result of the setting key operation detection switch 92 indicates the first to third rotation ranges sequentially. Further, the CPU 200 determines that an abnormality has occurred when the determination result of the time determination means indicates that a predetermined time has been exceeded. In this case, the CPU 200 determines that the abnormality has occurred. Since the determination of the setting change permission operation by the fixed change permission operation determination means is invalidated and the alarm notification means issues an alarm, it is possible to prevent the winning combination winning probability setting display and setting change from being performed illegally. .

  Further, the CPU 200 of the main control board 20 does not perform the unlocking operation using the front door key 600 with respect to the front door cylinder lock rotor 612, and the detection result of the front door opening detection switch 85 indicates the front door 3. If the setting cylinder lock rotor 812 is rotated when the front door 3 is closed, it is considered that an abnormality has occurred.
