[Example 1]

FIG. 4 is a block diagram of the main part of the control circuit in the first embodiment, FIG. 5 is a time chart showing the operation timing of the control circuit, and FIG. 6 is a display example similarly displayed on the display screen.

[0043] The sub-control board 5 includes a ROM 31 and a CPU 32 that store control programs and data. A control unit 30 that constitutes a control means configured as an integrated one-chip CPU together with a RAM 33 that functions as a work area, a backup power supply 34 that supplies power only to a predetermined part, and a timer circuit part 35 that constitutes a timer means And a clock module 36 that serves as a timekeeping means for measuring the time when the detection sensor 60 detects the opening and closing of the front door 3, and a memory 37 that serves as a storage means for storing the opening and closing state of the front door 3. . Note that the memory 37 in the first embodiment is a static random access memory (SRAM) that does not require an operation for holding memory in order to reduce the power consumption of the knock-up power supply 34, or a flash that requires power only during operation. It is preferable to use a nonvolatile semiconductor memory such as a memory (flash memory). The memory 37 may be provided in the RAM 33 in the CPU 31.

[0044] The power of the backup power source 34 is supplied only to the control unit 30, the timer circuit unit 35, the clock module 36, the memory 37, and the door opening / closing detection sensor 60.

In response to this, the timer circuit unit 35 is operated by a knock-up power supply 34 for a predetermined time T (several milliseconds), and the power of the backup power supply 34 is supplied to the control unit 30 within the predetermined time T. Then, the control unit 30 is operated, and when the predetermined time T has elapsed, the timing operation is finished and the power supply of the backup power source 34 is stopped to the control unit 30. The predetermined time T is set based on the time required for the control unit 30 to store information in the memory 37.

[0048] The control unit 30 starts itself when the power of the backup power supply 34 is supplied. The date / time when the door opening / closing detection sensor 60 detects the opening of the front door 3 is read from the clock module 36 and stored in the memory 37.

[0049] After that, when the door open / close detection sensor 60 detects the closing of the front door 3 and a closing signal (for example, a LOW signal) is input to the timer circuit unit 35, the timer is triggered by this. The circuit unit 35 is operated again for a predetermined time T by the knock-up power supply 34, and the power of the knock-up power supply 34 is supplied to the control unit 30. When the predetermined time T elapses, the circuit unit 35 stops the time measuring operation. Then, the power supply of the backup power source 34 is stopped for the control unit 30.

[0050] The control unit 30 uses the clock module 36 to indicate the date and time when the power supply of the backup power source 34 is supplied, that is, the date and time when the door open / close detection sensor 60 detects the closing of the front door 3. Is stored in the memory 37.

[0051] Thereby, power consumption of the knock-up power supply 34 can be saved, and unauthorized opening / closing of the front door 3 when the power of the gaming machine 1 is cut off can be monitored over a long period of time. In addition, even when the front door 3 is open for a long time when the power is cut off, the power supply to the control unit 30 of the backup power supply 34 is only a short time T, so the power consumption of the backup power supply 34 is minimized. To the limit. As a result, the capacity of the backup power supply 34 can be reduced, and the security can be improved with the inexpensive and small backup power supply 34.

[0052] The information stored in the memory 37 is displayed on the display device 9 by operating the operation switch for abnormality confirmation 14 with the front door 3 opened when the gaming machine 1 is supplied with power. On the screen 91, the opening / closing information of the front door 3 detected by the door opening / closing detection sensor 60, for example, the date, time, open or closed can be displayed in time series as shown in FIG.

[0053] The gaming machine 1 in which the opening / closing information of the front door 3 is displayed on the display screen 91 of the display device 9 is judged as having a possibility of fraud, and the power to be carefully checked or a new gaming machine To be exchanged.

[0063] Knock-up power-on control signal generation unit 571 includes a CR circuit (chattering prevention circuit) including resistor R1 and capacitor C1, and both input terminals 573a and 573b between resistor R1 and capacitor C1, and resistor R. 1 consists of NAND gate 57 3 connected to door open / close detection sensor 60 via 1 and resistor R2 and capacitor C2 connected in series to output terminal 573c of NAND gate 573 to supply backup power to ROM51 and CPU52 CR circuit (delay circuit) that serves as a timer means to determine the time to be used, and both input terminals 574a and 574b are resistors R2. NAND gate 574 connected to the output terminal 573c of the NAND gate 573a and the input terminal 575c of the NAND gate 573 through the resistor R2 between the input terminal 573c and the other input. The terminal 575b is connected to the output terminal 574c of the NAND gate 574, and the output terminal 575c is provided with the NAND gate 575 connected to the ENB of the power supply switching unit 572.

Next, referring to the time chart shown in FIG. 10, the control of the power supply control unit 57 when external power is supplied to the gaming machine 1 will be described.

The door opening / closing detection sensor 60 is OFF when the closing of the front door 3 is detected. Therefore, when the front door 3 is closed, the high voltage is applied to both input terminals 573a and 573b of the NAND gate 573 because of the voltage Shigh at the point A of the CR circuit Rl and C1 of the power supply controller 57. The low signal is output from the output terminal 573c. Since the voltage at point B of CR circuits R2 and C2 at that time is low, a low signal is input to both input terminals 574a and 574b of NAND gate 574, and a high signal is output from output terminal 574c. Yes. As a result, a low signal power is input to one input terminal 575a of the NAND gate 575, and a high signal is input to the other input terminal 575b. Therefore, the knock-up power supply is turned on from the output terminal 575c of the NAND gate 575. A high signal is output as the control signal 103, and this signal is input to the ENB of the power supply switching unit 572. As a result, the power supply switching unit 572 does not output backup power from OUTB regardless of whether or not the gaming machine 1 is supplied with external power.

[0065] When the door open / close detection sensor 60 detects the opening of the front door 3 and turns ON to output the door open signal 102, the time constant of the CR circuits Cl and R1 of the power supply control unit 57 is set. After a time T 1 (for example, 22 msec), the voltage at the point A becomes low, and a low signal is input to both input terminals 573a and 573b of the NAND gate 573. As a result, a high signal is output from the output terminal 573c, and this high signal is input to one input terminal 575a of the NAND gate 575. The NAND gate 574 continues to output a high signal from its output terminal 574c until the voltage at point B of the CR circuits C2 and R2 changes to high due to the high signal output from the output terminal 573c. Continue to input the signal to the input terminal 575b of the NAND gate 575. In this embodiment, as shown in FIG. 9, the inputs of the NAND circuits 573 and 574 Terminals 573a and 574a are connected to input terminals 573b and 574b respectively.Input terminals 57 3a and 574a can be connected to the high level (DCV) of the power supply for stability against signal fluctuations due to noise, etc. The input terminals 573a and 574a are preferably connected to the high level (DCV) of the power supply.

As a result, the NAND gate 575 has a period until the output terminal 573c of the NAND gate 573 outputs a high signal and the output terminal 574c of the NAND gate 574 outputs a low signal, that is, CR circuits R2, C2 A low signal is output as the backup power-on control signal 103 from the output terminal 575c for a time T2 (for example, 33 msec) based on the time constant of

[0067] When the backup power-on control signal 103 output from the output terminal 575c of the NAND gate 575 is input to the ENB, the power switching unit 572 outputs the backup power from OUTB and supplies it to the ROM 51 and the CPU 52. To do.

[0068] Then, when time T2 elapses after the backup power is supplied to the ROM 51 and the CPU 52, the voltage at the point B changes to high at that time, and a low signal is output from the output gate 574c of the NAND gate 574. In response to the output, the NAND gate 575 outputs a high signal from its output terminal 575c, and the power supply switching unit 572 stops the output of the backup power from OUTB.

[0069] CPU 52 is driven by the supply of backup power from power supply control unit 57, and an abnormal situation occurs in gaming machine 1 when external power is not supplied to gaming machine 1. As a result, the date and time when the door open / close detection sensor 60 output from the door open / close detection sensor 60 is received is read from the clock module 56 and stored in the RAM 53, and the backup power is supplied from the power supply control unit 57. When time T2 elapses, the knock-up power is stopped and the drive is stopped.

As described above, in the second embodiment, when the external power is not supplied to the gaming machine 1, the time for which the CPU 52 consumes the power of the backup power supply 55 is to allow the CPU 52 to store the date / time information in the RAM 53. Since only a short time T2 is required, the power consumption of the backup power supply 55 can be saved, and the incorrect opening of the front door 3 when the machine 1 is turned off should be monitored over a long period of time. Can do. Also, when power is cut off, front door 3 is long Even in the open state, the power supply of the backup power supply 55 to the CPU 52 is only for the time T2, so that the power consumption of the backup power supply 55 can be minimized. As a result, the capacity of the knock-up power supply 55 can be reduced, and security can be improved with the inexpensive and small backup power supply 55.

[0071] The information stored in the RAM 53 by the CPU 52, that is, the date and time when external power is applied to the gaming machine 1, the date and time when the door open / close detection sensor 60 detects the opening of the front door 3, When external power is supplied to 1, by opening the front door 3 and operating the operation switch 14 for abnormality confirmation, the time is displayed on the display screen 91 of the display device 9, for example, in time series as shown in FIG. Can be made.

[0072] As shown in FIG. 11, the gaming machine 1 in which the opening information of the front door 3 is displayed on the display screen 91 of the display device 9 before the external power-on date is determined to be a possibility of fraud. And carefully checked or replaced with a new gaming machine.

[0073] (Example 3)

FIG. 12 is a block diagram of the main part of the control circuit according to the third embodiment of the present invention, FIG. 13 is a block diagram of the power supply control unit, and FIG. 14 is a circuit diagram showing an example of the power supply control unit. 15 is a time chart showing the operation timing of the control circuit, and FIG. 16 is a display example similarly displayed on the display screen.

The sub control board 5 stores opening / closing information when receiving an opening / closing signal from the door opening / closing detection sensor 60 and date / time information when external power is applied to the gaming machine 1. The opening / closing information includes date / time information when the door opening / closing detection switch 60 detects opening / closing of the front door 3 and power supply source identification information described later for identifying the power source at that time.

As shown in FIG. 12, the sub-control board 5 is connected to the ROM 51 storing the control program and various data, the control command output from the main control board 4, and the external power supply device 8 connected to the external power supply. The CPU 52 is a control means for reading the external power-on signal 101 and the open / close signal 102 output from the door open / close detection sensor 60 via the IZO port 54, and the RAM 53 is a storage means for storing various information by the CPU 52. And external power supply (for example, voltage 3.3V) is stopped (external power supply device 8 is not connected to external power supply or external power supply device 8 is OFF) ), CPU52 works Rechargeable backup power supply 55 that can supply the necessary backup power (for example, voltage 3V), clock module 56 that provides timekeeping means that can always be driven by external power or backup power, ROM51, CPU52, RAM53 In addition, a power supply control unit 50 for controlling power supplied to the clock module 56 is mounted.

[0076] When the external power is not supplied to the gaming machine 1, the CPU 52 detects, for example, a period during which the gaming machine 1 is transported to a production factory or a game shop, a period outside the business hours of the game shop, and a door open / close detection sensor. When the open / close signal 102 is output from 60, the backup power output from the CPU power supply control unit 500 of the power supply control unit 50 is activated by the backup power output and receives the open / close signal 102a. The RAM 53 stores the power supply information indicating that the power supply source at that time is the knock-up power. In addition, the external power supply device 8 is connected to an external power source by installing the gaming machine 1 in a gaming store, etc., and external power is input to the gaming machine 1, whereby the CPU 52 transmits from the main control board 4. The RAM 53 stores the date and time information when the external power is turned on based on the external power on signal 101. Furthermore, during the period when external power is supplied to the gaming machine 1, for example, during the operating hours of the amusement store, the CPU 52 is driven by the external power output from the CPU power supply control unit 500, and the door open / close detection is performed. When the open / close signal 102a from the sensor 60 is received, the RAM 53 stores the date / time information when the open / close signal 102a at that time is received and the power supply information for identifying that the power supply source at that time is external power.

[0077] The date and time information when the open / close signal 102a of the information stored in the RAM 53 is received, the power supply information for identifying the power supply source, and the date and time information when the external power source is turned on are the open and closed date and time information 201, 202, power supply source identification information 204, and external power-on date / time information 203 can be displayed on the display screen 91 of the display device 9 as shown in FIG.

The power supply control unit 50 includes a CPU power supply control unit 500 that controls the power supplied to the ROM 51 and the CPU 52, and a RAM power supply control unit 550 that controls the power supplied to the RAM 53 and the clock module 56. RU

As shown in FIG. 13, the CPU power supply control unit 500 outputs a backup power based on the signal processing unit 510 that processes the open / close signal 102a output from the door open / close detection sensor 60 and the open / close signal 102a. Backup power supply control signal 103 for generating A backup power-on control signal generation unit 520, and a CPU power switching unit 530 capable of switching the DCV 65 supplied to the ROM 51 and the CPU 52 to external power or backup power.

The RAM power supply control unit 550 includes a RAM power supply switching unit 560 that can switch the power source supplied to the RAM 53 and the clock module 56 to external power or knock-up power.

[0081] As shown in FIG. 14, the signal processing unit 510 of the CPU power supply control unit 500 is formed by a CR circuit including a resistor R1 and a capacitor C1 connected in series to the door opening / closing detection sensor 60. Chattering of the open / close signal output from the detection sensor 60 is prevented.

[0082] Knock-up power-on control signal generation unit 520 includes an AND gate 521 in which both input terminals 521a and 521b are connected between resistor R1 and capacitor C1 and through resistor R1 to door opening / closing detection sensor 60. A CR circuit (delay circuit) comprising a resistor R2 and a capacitor C2 connected in series to the output terminal 521c of the NAND gate 521, and serving as a timer means for determining the time for supplying backup power to the ROM 51 and the CPU 52. Input terminal 522a, 522b is connected between resistor R2 and capacitor C2 and connected to output terminal 521c of NAND gate 52 la via resistor R2, NAND gate 522 and one input terminal 523a is the output of NAND gate 521 NAND gate 523 connected to terminal 521c, the other input terminal 523b connected to output terminal 522c of NAND gate 522, and one input terminal 524a connected to output terminal 521c of NA ND gate 521, the other input Terminal 524b is NAND The OR gate 524 connected to the output terminal 522c of the gate 522, one input terminal 525a is connected to the output terminal 524c of the OR gate 524, and the other input terminal 525b is connected to the output terminal 523c of the NAND gate 523. The output terminal 525c further includes an AND gate 525 connected to the ENB of the CPU power supply switching unit 530.

[0083] When the low signal is input to at least one of the input terminals 525a and 525b, the AND gate 525 outputs the backup power supply control signal 103 of the low signal from the output terminal 525c, and the CPU 52 sends the open / close information to the RAM 53. Outputs only for the predetermined time required to memorize.

[0084] The CPU power switching unit 530 has a built-in 2-channel power switching IC, and its input side External power is input to INA, backup power is input to INB, and backup power supply control signal 103 output from AND gate 525 of backup power-on control signal generator 520 is input to ENB. The When external power is supplied to gaming machine 1, that is, when external power is input to INA, knock-up power supply control signal 103 is related to whether or not power is input to ENB. Is output. In addition, when external power is not supplied to the gaming machine 1, that is, when external power is not input to the INA, only when the backup power supply control signal 103 is input to the ENB, the OUTB power is also sent to the RAM 53 by the CPU 52. Backup power is output for a predetermined time required to store the switching information. In addition, when external power is input to INA of CPU power supply switching unit 530 and backup power is input to INB, the higher power of the power input to INA and INB is output from OUTA or OUTB to D. Output as CV65. In Embodiment 3 of the present invention, the external power is set to 3.3 V and the backup power is set to 3 V. Therefore, when each power is supplied to INA and INB, the external power is supplied from OUTA. Backup power is not output.

[0085] The RAM power switching unit 560 has a built-in 2-channel power switching IC similar to the CPU power switching unit 530. External power is input to the INA on the input side, and backup is performed to the INB. When power is input and each power is input to INA and INB, OUTA force also outputs external power. In addition, when external power is not supplied to gaming machine 1, backup power is output from OUTB, and when external power is input to INA, output of backup power is stopped and OUTA force external power is output. Output and reduce the power consumption of the backup power supply 55.

[0086] When external power is supplied to gaming machine 1, knock-up power supply 55 is charged by the external power supply.

Next, referring to the time chart shown in FIG. 15, when the external power is supplied to the gaming machine 1 and it is V, the control of the CPU power supply control unit 500 in the power supply control unit 50 is performed. I will explain.

The door open / close detection sensor 60 is OFF when the closing of the front door 3 is detected. Gatsutsu When the front door 3 is closed, the voltage power at the point A of the CR circuit Rl, C1 of the CPU power supply control unit 500 is ¾iigh, so high signals are input to both input terminals 521a, 521b of the NAND gate 521. As a result, a low signal is also output from the output terminal 521c force. At this time, since the voltage at point B of the CR circuits R2 and C2 is low, a low signal is input to both input terminals 522a and 522b of the NAND gate 522, and a high signal is output from the output terminal 522c.

[0088] When the high signal is output from the output terminal 522c of the NAND gate 522, the NAND gate 523 is connected to the input terminal 523a of the low signal output from the output terminal 521c of the NAND gate 521 and the input terminal 523b. Since the high signal output from the output terminal 522c of the NAND gate 522 is input to the output terminal 523c, the high signal is output from the output terminal 523c. In the OR circuit 524, the low signal output from the output terminal 521c of the NAND gate 521 is input to the input terminal 524a, and the high signal output from the output terminal 522c of the NAND gate 522 is input to the input terminal 524b. Therefore, a high signal is output from the output terminal 524c.

[0089] As a result, the AND circuit 525 receives a high signal at its input terminals 525a and 525b, outputs a high signal that is not the backup power-on control signal 103 from its output terminal 525c, Input to ENB of CPU power supply switching unit 530. As a result, the CPU power switching unit 530 does not output backup power even for the OUTB force regardless of whether or not external power is supplied to the gaming machine 1.

[0090] When the door open / close detection sensor 60 detects the opening of the front door 3 and outputs an open signal 102, the time T1 (based on the time constant of the CR circuits Cl and R1 at that time (point a shown in FIG. 15)) For example, after 22ms ec), the voltage at point A goes low. Therefore, the NAND gate 521 receives a low signal at both input terminals 521a and 521b when the time T1 has elapsed (point b shown in FIG. 15), and the output terminal 521c also outputs a high signal. When a high signal is also output from the output terminal 521c, the NAND gate 522 outputs a high voltage from its output terminal 522c until the voltage at point B of the CR circuits C2 and R2 changes to high after a time T2 (for example, 33 msec). Continue signal output. Then, when a high signal is output from the output terminal 521c of the NAND gate 521, the NAND gate 523 outputs a low signal from the output terminal 523c.

[0091] When a low signal is output from the output terminal 523c of the NAND gate 523, the AND gate 525 The high signal is input to the input terminal 525a and the low signal is input to the input terminal 525b, and the low signal that forms the backup power-on control signal 103 is output from the output terminal 525c. Input to ENB. As a result, the CPU power supply switching unit 530 also outputs the backup power for the OUTB force.

[0092] Then, when the time T2 elapses after the OUTB force of the CPU power supply switching unit 530 also outputs the backup power, the voltage at the B point of the CR circuits R2 and C2 at that time (point c shown in FIG. 15) Since it becomes high, the NAND gate 522 receives a high signal at its input terminals 522a and 522b, and outputs a low signal from the output terminal 522c. As a result, the NAND gate 523 receives a low signal at its input terminal 523b and outputs a high signal from the output terminal 523c.

[0093] When a high signal is output from the output terminal 523c of the NAND gate 523, the AND gate 525 receives a high signal from the input terminals 525a and 525b, and outputs a high signal from the output terminal 525c. . In response to this, the CPU power supply switching unit 530 stops the output of backup power from OUTB.

[0094] The CPU 52 starts when the backup power is supplied from the CPU power switching unit 530 of the CPU power supply control unit 500, and when the gaming machine 1 is not supplied with external power, the gaming machine 1 Assuming that an abnormal situation has occurred, the date and time when the open signal is received from the open / close signal 101a output from the door open / close detection sensor 60 is read from the clock module 56 and stored in the RAM 53. The power supply source information indicating that the power source at that time is backup power is also stored in the RAM 53, and is stopped after the time T2.

[0095] When external power is not supplied to the gaming machine 1, the backup power supplied to the CPU 52 is related to the time when the front door 3 is open. The CPU 52 opens and closes the front door 3 to the RAM 51. Since only the time T2 required to store the information is required, even if the front door 3 is left open for a long time, the power of the backup power supply 55 is not wasted.

[0096] Subsequently, when the front door 3 is closed from the open state, at that time (point d shown in FIG. 15), the door open / close detection sensor 60 is switched OFF and the close signal of the open / close signal 102a is output. When output, the voltage at point A becomes high after time T1 based on the time constant of CR circuit Cl, R1. For this reason, the NAND gate 521 receives both inputs when the time T1 has elapsed (point e shown in FIG. 15). A high signal is input to terminals 521a and 521b, and a low signal is output from output terminal 521c. When a low signal is output from the output terminal 521c, the NAND gate 522 outputs that output terminal 522c power low signal for the period until the voltage at point B of the CR circuit C2, R2 changes to low after the time T2. Continue. The OR gate 524 outputs a low signal from the output terminal 524c when the output terminal 521c of the NAND gate 521 outputs a low signal.

[0097] When a low signal is output from the output terminal 524c of the OR gate 524, the AND gate 525 receives a low signal from the input terminal 525a and a high signal from the input terminal 525b, and the backup power supply from the output terminal 525c. The low signal that constitutes the input control signal 103 is output, and the signal is input to the ENB of the CPU power supply switching unit 530. As a result, the CPU power supply switching unit 530 outputs backup power from OUTB.

[0098] Then, when the time T2 elapses after the OUTB force of the CPU power supply switching unit 530 also outputs the backup power, the voltage at the B point of the CR circuits R2 and C2 at that time (point f shown in FIG. 15) Therefore, the NAND gate 522 receives a low signal at both its input terminals 522a and 522b and outputs a high signal from the output terminal 522c. As a result, the OR gate 524 receives the high signal at its input terminal 524b and outputs a high signal from the output terminal 524c.

When a high signal is output from the output terminal 524c of the OR gate 524, the AND gate 525 receives a high signal from its input terminals 525a and 525b, and outputs a high signal from the output terminal 525c. In response to this, the CPU power supply switching unit 530 stops outputting backup power from OUTB.

[0100] The CPU 52 starts up again when the backup power is supplied from the CPU power supply switching unit 530 of the CPU power supply control unit 500, and when the gaming machine 1 is not supplied with external power, Assuming that an abnormal situation has occurred in Unit 1, the date and time when the closing signal is received from the opening / closing signal 102a output from the door opening / closing detection sensor 60 is read from the clock module 56 and stored in the RAM 53. Then, the power supply source information indicating that the power source at that time is backup power is also stored in the RAM 53 and stopped after the time T2.

Next, a method for confirming the opening / closing information stored in the RAM 53 will be described. To gaming machine 1 When external power is supplied, the information stored in RAM 53 by the CPU 52 of the sub control board 5, for example, the front door 3 is opened by opening the front door 3 and operating the operation switch 14 for abnormality confirmation. Opening date / time information 201, closing date / time information 202 when front door 3 is closed, external power-on date / time information 203 when external power is applied to gaming machine 1, and when front door 3 is opened / closed The power supply source identification information 204 for identifying whether the power supplied to the CPU 52 is external power backup power is displayed on the display screen 91 of the display device 9 in time series as shown in FIG. 3 open / close information etc. can be confirmed.

[0102] For example, as shown in FIG. 16, it is assumed that the gaming machine 1 in which the opening / closing information of the front door 3 is displayed on the display screen 91 of the display device 9 before the external power-on date is likely to be fraudulent. It will be judged and carefully checked or replaced with a new game machine.

[0103] Although the embodiments of the present invention have been described above, the following various modifications and changes can be made to the embodiments without departing from the gist of the present invention. .

(i) Instead of a slot machine in which the game medium is a medal (including coins), the gaming machine 1 is a pachinko machine, a slot machine, and other gaming machines in which the game medium is a pachinko ball.

(ii) The door open / close detection sensor 60 is a photoelectric non-contact type sensor that operates with the power of the knock-up power supply 55, instead of a mechanical limit switch.

Other abnormal situations include removal / removal of the board box containing the main control board 4, abnormal tilt and vibration of the gaming machine 1 caused by the movement of the gaming machine 1, etc., and the insertion of unauthorized tools into the housing 2. Detection of abnormal pressure load due to.

(iv) As a display device for displaying the abnormality information, instead of the display device 9 for displaying the abnormality information on the front surface of the front door 3 as in the above embodiment, A separate display device dedicated to displaying information is provided.
