On the other hand, if it is determined that the guide rail ball flag is ON, the process proceeds to step 65, and after the guide rail ball presence abnormality flag is turned ON, the control exits from the abnormality flag setting process subroutine to control the abnormality flag setting process. Exit.

  Returning to the ball lifting apparatus substrate processing of FIG. 7, after exiting the abnormality flag setting processing of step 11, a subroutine of abnormality notification processing is performed in step 12. In the abnormality notification process shown in FIG. 10, it is determined in step 70 whether or not the shutter opening abnormality flag is ON. If it is determined that the shutter release abnormality flag is ON, “1” is displayed on the abnormality code display 81 in step 71, and the process proceeds to step 73. If it is determined that the shutter release abnormality flag is not ON, the process proceeds to step 73 as it is without displaying “1” on the abnormality code display 81 in step 72.

If it is determined that the shutter closing abnormality flag is ON, “2” is displayed on the abnormality code display 81 in step 74, and the process proceeds to step 76. If it is determined that the shutter closing abnormality flag is not ON, the process proceeds to step 76 as it is without displaying “2” of the abnormality code display 81 in step 75.

  In step 76, it is determined whether or not the guide rail closing abnormality flag is ON. If it is determined that the guide rail closing abnormality flag is ON, “3” is displayed on the abnormality code display 81 in step 77, and the process proceeds to step 79. If it is determined that the guide rail closing abnormality flag is not ON, the routine proceeds directly to step 79 without displaying “3” on the abnormality code display 81 in step 78.

  In step 79, it is determined whether or not the guide rail ball presence abnormality flag is ON. If it is determined that the guide rail presence abnormality flag is ON, “4” is displayed on the abnormality code display 81 in step 80, and the process proceeds to step 82. If it is determined that the guide rail presence abnormality flag is not ON, the process proceeds directly to step 82 without displaying “4” on the abnormality code display 81 in step 81.

  In step 82, it is determined whether or not the flash lamp flag is ON. If it is determined that the flash lamp flag is ON, “5” is displayed on the abnormality code display 81 in step 83, and the process proceeds to step 85. If it is determined that the flash lamp flag is not ON, the process proceeds to step 85 as it is without displaying “5” on the abnormality code display 81 in step 84.

  In step 85, it is determined whether or not the overflow flag is ON. If it is determined that the overflow flag is ON, “6” is displayed on the abnormality code display 81 in step 86, and the process proceeds to step 88. If it is determined that the overflow flag is not ON, the process proceeds directly to step 88 without displaying “6” in the abnormal code display 81 in step 87.

  In step 88, it is determined whether or not there is a display on the abnormal code display 81 (display of “1” to “6”). If it is determined that there is a display on the abnormality code display 81, the abnormality notification lamp 89 is lit red in step 89, the process exits from the abnormality notification processing subroutine, and proceeds to step 13 of the doffing board processing. If it is determined that there is no display on the abnormality code display 81, the abnormality notification lamp 89 is turned off in step 90, the process exits from the abnormality notification processing subroutine, and proceeds to step 13 of the doffing board processing. In addition, when there are a plurality of displays on the abnormal code display 81, a plurality of displays are displayed in order at predetermined time intervals.

  Returning to the ball lifting apparatus substrate process of FIG. 7, after exiting the abnormality notification process of step 12, an operation process subroutine is performed in step 13. This operation processing is based on the fact that the system operation switch 80b of the ball lifting device substrate 80 is pressed and turned ON, and the shutter device 54 is opened from the start of the drive motor 4 of the ball lifting device 1 to move the ball lifting device. This is a control process for automatically performing the flow until the ball is supplied to 1.

  In the operation process shown in FIG. 11, it is determined in step 100 whether or not the system operation switch 80b is ON. If it is determined in step 100 that the system operation switch 80b is not ON, the operation process subroutine is exited, and the operation process control is terminated. If it is determined that the system operation switch 80b is ON, the process proceeds to step 101, where it is determined whether or not the drive motor flag is OFF. If it is determined in step 101 that the drive motor flag is not OFF, the operation processing subroutine is exited, and the operation processing control is terminated. On the other hand, if it is determined in step 101 that the drive motor flag is OFF, the process proceeds to step 102 and it is determined whether or not the guide rail closing flag is ON.

If it is determined in step 102 that the guide rail closing flag is not ON, after the guide rail closing abnormality flag is turned ON in step 103, the operation processing subroutine is exited, and the ball lifting device substrate processing main routine is executed. Proceed to step 14. On the other hand, if it is determined that the guide rail closing flag is ON, the drive motor 4 of the ball lifting device 1 is started in Step 104 and the conveyor belt 6 is rotated, and the timer 01 is started in Step 105. After the timer 01 is started, it is determined in step 106 whether or not the timer 01 has passed a predetermined time.
The predetermined time is several seconds (for example, 5 seconds). The time of several seconds is such that after the drive motor 4 of the ball lifting device 1 is started, the conveyor belt 6 circulated by the drive motor 4 has a constant rotational speed. It is enough time.
When the timer 01 expires, the shutter motor 90 starts to open in order to open the shutter device 54 in step 107, and the timer 02 starts in step 108. When the shutter motor 90 starts to open, it is determined in step 109 whether or not the shutter open detection sensor 65 is turned on. If it is determined that the shutter motor 90 is turned on, the shutter motor 90 is stopped in step 110 and the operation process is performed. Control of the operation process is finished.

On the other hand, if it is determined in step 109 that the shutter release detection sensor 65 is not turned on, it is determined in step 111 whether or not the timer 02 has passed a predetermined time.
The predetermined time is, for example, 10 seconds, and this time of 10 seconds is sufficiently longer than the time from when the shutter motor 90 of the shutter device 54 is started until the shutter opening detection sensor 65 is turned on. .
Step 109 and step 111 are repeated until the timer 02 has elapsed 10 seconds. However, when it is determined in step 111 that the timer 02 has elapsed 10 seconds, that is, the shutter release detection sensor 65 is not turned ON for 10 seconds. When the period of time elapses, it means that some abnormality has occurred in the shutter device 54, so that the shutter opening abnormality flag is turned ON in step 112, and then the shutter motor 90 is stopped in step 110, and the operation processing subroutine is exited. Thus, the control of the operation process ends.

  Returning to the ball lifting apparatus substrate process of FIG. 7, after exiting the operation process of step 13, a stop process subroutine is performed in step 14. This stop processing is based on the fact that the system stop switch 80c of the ball lifting device substrate 80 is pressed and turned on, and then the shutter device 54 is closed and the supply of the balls to the ball lifting device 1 is stopped. This is a control process for automatically performing the flow until the drive motor 4 of the lifting device 1 is stopped.

In the stop process shown in FIG. 12, it is determined in step 120 whether or not the system stop switch 80c is ON. If it is determined in step 120 that the system stop switch 80c is ON, the process proceeds to step 121, and it is determined whether or not the drive motor flag is ON. If it is determined that the system stop switch 80c is not ON, the routine proceeds to step 122, where it is determined whether or not the overflow flag is ON. If it is determined in step 122 that the overflow flag is ON, the process proceeds to step 121 as it is. If it is determined that the overflow flag is not ON, the stop processing subroutine is exited and the control of the stop processing is ended. To do. If it is determined in step 121 that the drive motor flag is not ON, the process exits from the stop process subroutine and ends the stop process control. If it is determined in step 121 that the drive motor flag is ON, the process proceeds to step 123, and in order to close the shutter device 54 in step 123, the shutter motor 90 starts the closing drive, and in step 124 the timer 01 is set. Start. After the timer 01 is started, it is determined in step 125 whether or not the shutter closing detection sensor 64 has been turned on. If it is determined that the shutter has been turned on, the shutter motor 90 is stopped in step 126.
On the other hand, if it is determined in step 125 that the shutter closing detection sensor 64 is not turned on, it is determined in step 127 whether or not the timer 01 has passed a predetermined time.
The predetermined time is, for example, 10 seconds, and this time of 10 seconds is sufficiently longer than the time until the shutter closing detection sensor 64 is turned on after the shutter motor 90 of the shutter device 54 is started. .
Steps 125 and 127 are repeated until the timer 01 has elapsed 10 seconds. However, when it is determined in step 127 that the timer 01 has elapsed 10 seconds, that is, 10 seconds without the shutter closing detection sensor 64 being turned on. When the period of time elapses, it means that some abnormality has occurred in the shutter device 54, so that the shutter closing abnormality flag is turned on in step 128, and then the shutter motor 90 is stopped in step 126.

After the shutter motor 90 is stopped, the timer 02 is started in step 129, and it is determined in step 130 whether or not the timer 02 has passed a predetermined time.
The predetermined time is, for example, 20 seconds, and this time of 20 seconds is the ball lifting device after the shutter motor 90 of the shutter device 54 is stopped and the supply of the ball to the ball lifting device 1 is stopped. This time is sufficiently longer than the time required for all the pachinko balls in 1 to be discharged from the discharge bowl 25 to the outside of the ball lifting device 1.
Step 130 is repeated until the timer 02 has elapsed 20 seconds. If it is determined that the timer 02 has elapsed 20 seconds, the drive motor 4 of the ball lifting device 1 is stopped in step 131 and the ball lifting device 1 is stopped. Then, the process exits from the stop process subroutine, and the control of the stop process ends.

  Returning to the ball lifting device substrate process of FIG. 7, after exiting the stop process of step 14, a guide rail opening / closing process subroutine is performed in step 15. This guide rail opening / closing process is a control process for moving the engagement protrusion 41 according to the situation based on the guide rail switches 80d and 80e being pressed and turned ON.

  In the guide rail opening / closing process shown in FIG. 13, it is determined in step 140 whether or not the guide rail opening switch 80d is ON. If it is determined in step 140 that the guide rail release switch 80d is ON, the process proceeds to step 141, and it is determined whether or not the drive motor flag is OFF. If it is determined in step 141 that the drive motor flag is not OFF, the subroutine of the guide rail opening / closing process is exited, and the control of the ball lifting device substrate process is ended.

  On the other hand, if it is determined in step 141 that the drive motor flag is OFF, the process proceeds to step 142, and it is determined whether or not the guide rail ball flag is OFF. If it is determined in step 142 that the guide rail ball flag is OFF, the process proceeds to step 143, where the guide rail release solenoid 38 attached to the feed cylinder body 3 is turned ON, whereby the engagement protrusion 41 is The guide rail 20 is moved to the buried position, and the guide rail 20 can be opened and closed. Then, the subroutine of the guide rail opening / closing process is exited, and the control of the ball lifting device substrate process is completed. If it is determined in step 142 that the guide rail ball flag is not OFF, the process proceeds to step 144, and after the guide rail ball abnormality flag is turned ON, the subroutine of the guide rail opening / closing process is exited, and the ball lifting device substrate processing is performed. This completes the control.

On the other hand, if it is determined in step 140 that the guide rail opening switch 80d is not ON, the process proceeds to step 145, and it is determined whether or not the guide rail closing switch 80e is ON. If it is determined in step 145 that the guide rail closing switch 80e is not ON, the subroutine of the guide rail opening / closing process is exited, and the control of the ball lifting device substrate process is ended. If it is determined in step 145 that the guide rail closing switch 80e is ON, the process proceeds to step 146, where the guide rail opening solenoid 38 attached to the feed cylinder main body 3 is turned OFF. Is moved to the protruding position, and the guide rail 20 can be fastened. Then, the subroutine of the guide rail opening / closing process is exited, and the control of the ball lifting device substrate process is completed.
The ball lifting apparatus substrate processing performed by the above described ball lifting apparatus substrate 80 is repeatedly performed.

Next, the content of the abnormality, the cause, the coping method, etc. will be described in detail.
The shutter opening abnormality occurs when the shutter opening detection sensor 65 is not turned ON after the shutter motor 90 is opened (step 107) (NO in step 109) and a predetermined time has elapsed (YES in step 111). Is determined to have occurred.
If it is determined that this abnormality has occurred, the shutter opening abnormality flag is turned ON (step 112), and the abnormality code “1” is displayed on the abnormality code display 81 based on this flag (step 71), and the abnormality notification lamp is displayed. 89 is lit in red (step 89) to notify the outside.
This abnormality is mainly caused by the shutter device 54 biting a pachinko ball or the shutter device 54 being damaged due to aging or the like.
If the cause of the abnormality is that the shutter device 54 bites the pachinko ball, the switch 80a is operated to switch to the manual mode, the shutter forced switches 80j and 80k are operated to remove the bited pachinko ball, and the shutter device 54 54 is opened (the state shown in FIG. 4B).
When the cause of the abnormality is damage to the shutter device 54, the shutter device 54 is replaced, and the shutter device 54 is opened by the above-described manual operation.
As described above, when the abnormality is resolved and the shutter device 54 is opened, the shutter opening detection sensor 65 is turned on, so that the shutter opening flag is turned on (step 23 is YES, step 24). Based on this flag, the shutter is opened. When the opening abnormality flag is turned off (step 51 is YES, step 52), the display of the abnormality code display 81 and the lighting of the abnormality notification lamp 89 are automatically turned off (steps 72 and 90), and the countermeasure is taken. Is completed.

The shutter closing abnormality is detected when the shutter closing detection sensor 64 is not turned on after the shutter motor 90 is driven to close (step 123) (NO in step 125) and a predetermined time has elapsed (YES in step 127). Is determined to have occurred.
If it is determined that this abnormality has occurred, the shutter closing abnormality flag is turned on (step 128), and the abnormality code “2” is displayed on the abnormality code display 81 based on this flag (step 74), and the abnormality notification lamp is displayed. 89 is lit in red (step 89) to notify the outside.
