2. Description of the Related Art In a game hall having a plurality of gaming machines,
It is necessary to detect a plurality of game data for each gaming machine and perform an alarm or a totaling process. For this reason, a gaming machine management device is provided near each gaming machine, information output signals from each gaming machine and peripheral devices of the gaming machine are input, aggregation processing is performed, and data is transmitted to the central management computer side. Was. Further, the gaming machine management device sends a control signal from a central management computer to the gaming machine and peripheral devices of the gaming machine via an output interface circuit.

Of the game data from the gaming machine and the peripheral devices of the gaming machine, the money amount-related information regarding money is particularly important information and should not be erroneous.
The amount of money-related information is set on a machine rental machine (a machine ball rental machine or a machine coin rental machine), a rental machine signal from a general rental machine, a game machine installation island, etc., and is obtained by the player as a result of the game. There is a prize ball signal from the prize ball counter that counts the number of prize balls to be exchanged, and a safe signal from the depositing device. If the signal cable of these price related information is broken or the connection is bad,
Because of the serious loss of information, a means of detecting disconnections was included.

It had a circuit as shown in FIG. The information output from the gaming machine and the peripheral device side of the gaming machine is a normally closed contact such as the switch SW1. The information pulse is such that the switch SW1 is opened for about 10 msec, and the input interface circuit 326 converts it into a voltage pulse. Even when the signal cable 328 is broken, the input interface circuit 3 is used in the same manner as the information pulse.
The output of 26 becomes high level, but its pulse width is generally much longer than the pulse width of the information pulse of about 10 msec. In the gaming machine management device, the output pulse of the input interface circuit 326 is monitored, and if the pulse width is 100 msec or more for a certain period of time, it is determined that the signal cable 328 is broken. Further, when the signal cable 328 is short-circuited, the state is the same as when the switch SW1 is closed and the information does not reach, but a means for detecting such a signal cable short-circuit is not attached.

For the game hall, the amount-of-money related information about money is important information relating to the profit and loss of the store, and the error must be minimized. The conventional signal cable disconnection detecting means monitors the output pulse of the input interface circuit, that is, the input signal from the input port of the gaming machine management device, and detects that the pulse width of the input signal is a certain time or more. Because of this, there was a time delay, and even if there was a break in the signal cable, it could not be detected immediately. Also,
There is a drawback in that a short-time disconnection state, which occurs when the connector of the signal cable is attached / detached or the connector is not properly connected, is determined to be an information pulse. Furthermore, it was not possible to detect a short circuit in the signal cable.

Therefore, the present invention provides a gaming machine management device capable of immediately detecting a wire breakage of a signal cable of money amount related information and detecting a short circuit of the signal cable. The purpose is to

FIG. 5 is a block diagram showing the circuit configuration of the control board 31 of the platform management device 3. The basic circuit 311 includes a CPU circuit as an example of data processing means, a ROM and an R.
The game data of the pachinko machine 4 corresponding to the platform management device 3 is collected and stored in the RAM of the memory in accordance with the program stored in the memory, which is configured by a memory as an example of a storage unit including the AM. In addition, the basic circuit 31
1 controls a communication circuit 312 as an example of communication means, receives a command from the island management device 2, and if the address of the command matches the address of its own platform management device 3, it is stored in a memory. Necessary processing is performed according to the program and the response data is transmitted to the island management device 2.

The address setting circuit 313 is a circuit including a rotary switch and a DIP switch for setting a unique address of the platform control device 3, and this address becomes the address of the pachinko machine. The island management device 2 selects a specific pachinko machine from a plurality of pachinko machines on the island by this address.

The address decode circuit 315 decodes the address bus of the CPU, thereby creating a chip select signal to the input / output control board 32. The initial reset circuit 318 is a circuit for resetting the CPU and the like when the power is turned on. The power supply circuit 316 rectifies an AC power supply voltage from the outside and makes it a constant voltage, and shuts off the power supply in an emergency. The RAM backup power supply 317 monitors the power supply voltage and secures the power supply voltage for RAM backup even when the voltage drops. Therefore, the game data of the pachinko machine stored in the RAM is not lost due to an accident or the like.

The communication cable 10 is connected to the island management device 2. The display device 5 is connected to the other communication connector 31d via a connection cable. That is,
The communication connector 31d functions as a display output terminal. Since the communication connectors 31c and 31d are configured to perform communication by input / output of serial data, the connection cable can be made thinner and the number of connection terminals of the connector can be reduced as compared with the case of performing communication by input / output of parallel data. It is possible to easily connect the platform management device 3 as the machine management device and the island management device 2 and the platform management device 3 and the display device 5.

The circuit configuration of the control board 31 of the platform management device 3 in FIG. 5 is almost the same as that of the control board 21 of the island management device 2. However, one of the two communication connectors of the control board 21 of the island management device 2 is connected to the management computer 1, and the other is connected to the platform management device 3. The control board 31 of the platform management device 3 becomes the control board 21 of the island management device 2 by slightly changing the RAM capacity or the like. Since the printed patterns on the board are common, the manufacturing cost can be reduced by using common parts.

FIG. 6 shows the input / output control board 3 of the platform management device 3.
It is a block diagram showing the circuit configuration of FIG. Input / output circuit 32
1 is an input interface circuit for inputting input signals from various sensors of the pachinko machine 4 as data,
An output interface circuit for outputting a signal from the output port to the pachinko machine 4 is included. The input interface circuit is configured so that input signals from various sensors, that is, game data can be switched by a chip select signal from the address decoding circuit 315 in the control board 31. From the perspective of the CPU, different game data can be read by accessing different addresses. The basic circuit 311 in the control board 31 is programmed to read these game data at regular intervals and store them in the RAM.

The input interface circuit is as shown in FIG. Input terminal 1A of the connector 32c,
Immediately after 1B, the AC input terminal of the rectifier bridge P1 is connected and its output is used as an input pulse, so that it is a non-polar input terminal. Since it is possible to detect positive or negative polarity pulses in the same manner, malfunctions due to connector wiring mistakes are eliminated.

The input pulse is further passed through the Zener diode P2 and the three-terminal regulator P3 to the photocoupler P.
4 is driven with a constant current. Therefore, the signal path is insulated by the photocoupler P4 and is less likely to be affected by noise signals and the like. With this configuration, the input voltage of the input terminal of the input interface circuit is DC12V to 38V.
Can handle up to V. Therefore, the voltage signal can be detected even when the voltage of the information output line of the pachinko machine 4 differs depending on the manufacturer. Input voltage is 12V ~
When the output voltage is out of the range of 38V or when it is necessary to increase the number of input terminals, the input / output control board 32 is replaced.

FIG. 9 shows another interface circuit.
The terminals 3A and 3B of the connector 32b of FIG. 6 are input terminals for inputting the replenishment signal from the ball replenisher 6. Since the replenishment signal is a contact output, the interface circuit shown in FIG. 9 can be used for this signal. The circuit is simpler than that of FIG. 8, and the rectifier bridge P1 and the three-terminal regulator P3 are not used. In addition, a DC voltage of + 24V is output to one of the input terminals (terminal 3A).

Further, the terminals 1A of the connector 32b shown in FIG.
1B is a stop output to the pachinko machine 4, and this output circuit has a switching circuit as shown in FIG. Depending on the manufacturer, there are two types of pachinko machines that require a voltage signal and a contact signal as a stop signal (a signal for cutting off the power of the ball launching device). Can also handle. When the changeover switch P5 is set to the Y side, the output terminals 1A and 1B serve as contact outputs of the relay P6. When the changeover switch P5 is set to the X side, the output terminals 1A and 1B have a voltage output of + 24V.

The board-to-board connector 32a is connected to the control board 31.
The control board 31 and the input / output control board 32 are connected to each other by mutually connecting the inter-board connector 31a. The connectors 32b and 32c connect input signal lines from various sensors and reed switches and various output wirings to the input / output control board 32.

The circuit configuration of the control board 21 of the island management device 2 is the same as that of the control board 31 of the platform management device 3 of FIG.
The difference is that the RAM capacity in the basic circuit and the program in the ROM are different. By making the control board of the island management device 2 and the control board 31 of the platform management device 3 have the same circuit configuration, the control board can be shared, and the cost can be suppressed as much as possible.

FIG. 7 shows the input / output control board 2 of the island management system 2.
It is a block diagram showing the circuit configuration of FIG. Input / output circuit 22
1 is an input interface circuit for inputting an input signal from a safe, a ball lending machine, a ball counter, etc. as data,
And an output interface circuit for outputting a signal of the output port. The smoothing circuit 222 is a circuit for an output power supply and an input power supply. Display element 223
Is composed of a light emitting diode and functions as a display for monitoring communication reception signals, communication transmission signals, output port states, and the like.

The inter-board connector 22a connects the control board and the input / output control board 22 by mutually connecting with the inter-board connector of the control board. The connector 22b is an input signal line from various reed switches,
Also, the various output wirings are connected to the input / output control board 22.

Surface mounting is used for mounting the electronic components on the control board and the input / output control board of the island management device 2 and the platform management device 3, and the mounting density is increased to reduce the board area. Therefore, the island management device 2 and the platform management device 3
It also contributes to downsizing of the entire device.

Money related information relating to money is input to the island management device 2 and the platform management device 3 from various devices on the game machine installation island, the pachinko machine 4 and peripheral devices of the pachinko machine 4. Among various information signals, the money amount related information is particularly important information and should not be erroneous. The amount-related information includes the number of balls lent from the pedestrian ball lending machine or the general ball lending machine, or a renting machine signal indicating the amount of lent balls, the number of prize exchange game media from the prize ball counter (the result of the game is obtained by the player. There is a prize ball signal indicating the number of coins and coins to be exchanged for prizes, and a safe signal indicating the amount of money deposited from the deposit device. If the signal cable for these amount-of-money related information is disconnected or has a poor connection, the information will be seriously lost, and a means for detecting the disconnection is required.

Conventionally, as described above, the signal input circuit of the input interface circuit 326 has a circuit configuration as shown in FIG.
If it was 00 msec or more, it was determined that the signal cable 328 was broken. Therefore, a time delay of 100 msec occurs, and even if the signal cable is broken, it cannot be detected immediately. In addition, there is a drawback that a short-time disconnection state, which occurs when the connector of the signal cable is attached / detached or the connector is not properly connected, is determined to be an information pulse. Furthermore, it was not possible to detect a short circuit in the signal cable.

The second input / output circuit 321 includes a signal input circuit as shown in FIG. The terminal 6A, 6B of the connector 32b receives the rental machine signal from the inter-mountain ball rental machine. The information output of the inter-lens ball lending machine is a contact output, and its switch SW2 is a normally open contact. The switch SW2 is normally in an open state, but is closed for one pulse for 25 balls (100 yen) to be in a conductive state. The pulse width of 1 pulse is 1
It is about 0 msec. Input interface circuit 32
As the circuit 6, a circuit as shown in FIG. 9 can be used.

The input interface circuit 326 and the disconnection detection circuit 327 detect the voltage generated across the resistor R1. +24 in the normal state where the switch SW2 is opened
A voltage obtained by dividing V by R2 and R1 is detected. This voltage is set to a voltage level that is logically determined to be a low level by the input interface circuit 326, specifically, about 5V. The disconnection detection circuit 327 has a reference voltage smaller than this low level voltage, and is configured to generate a disconnection output when the detected voltage is smaller than this reference voltage. The reference voltage may be set to about 3V. As long as the low level voltage is detected,
Since it is higher than the reference voltage, disconnection output does not occur.

When the switch SW2 is closed to generate an output pulse, approximately +24 V is generated across the resistor R1,
The input interface circuit 326 naturally handles this voltage as a high level. The disconnection detection circuit 327 does not generate a disconnection output because it is higher than the reference voltage at this high level voltage.

When the signal cable 328 is broken, no current flows through the resistor R1 and no voltage is generated across it. Then, the detection voltage of the disconnection detection circuit 327 becomes lower than the reference voltage, and the disconnection detection circuit 327 sets the disconnection output to the high level. Since the disconnection output occurs at the same time as the disconnection of the signal cable 328, the disconnection can be immediately detected. When viewed from the control board 31 of the table management device 3, the information output of the input interface circuit 326 and the disconnection detection circuit 3
It is assigned to an input port different from the wire break output of 27, and by accessing each input port,
Each signal can be detected independently and immediately. When a disconnection is detected, the information is sent to the management computer 1 to perform appropriate alarm processing, or an alarm lamp is provided around the pachinko machine 4 or on the gaming machine installation island to light it. do it.

When the signal cable 328 is short-circuited, the switch SW2 is in the closed state, and the input interface circuit 326 processes it as a high level voltage. That is, the information output of the input interface circuit 326 becomes high level at this time. However, while the pulse width of the signal pulse of the switch SW2 is about 10 msec, the pulse width of the voltage pulse due to a general short-circuit accident is considerably longer than this, so that the signal cable 328 can be short-circuited by using this. Can be detected.

FIG. 13 shows a flow chart of the short circuit detection subroutine. This is a part of the program executed by the basic circuit 311 of the control board 31 of the platform management device 3, and is called every time the information output of the input interface circuit 326, that is, the input signal to the basic circuit 311 becomes high level. It is a subroutine. When the input signal becomes high level and the subroutine is called, the timer is first started in flow 371. A predetermined set time for distinguishing the information pulse and the short circuit signal is set in the timer. This set time is, for example, 10
Set to about 0 msec.

In the flow 372, it is judged whether or not the high level voltage of the input signal continues, and the judgment result is "No".
That is, if the input signal is at the low level, the pulse width is less than the set time, so the flow advances to flow 375, and data (for example, 1) is set to the return value of the subroutine. If the determination result of the flow 372 is “Yes”, the flow 3
Proceed to 73 to determine whether the timer has reached the set time. If this determination result is “No”, the flow 3
Returning to 72, repeat processing is performed. If the determination result of the flow 373 is “Yes”, the pulse width of the input signal is equal to or longer than the set time, and thus it can be determined that the short-circuited state. In this case, the process proceeds to flow 374, and the return value of the subroutine is set to the short circuit information (for example, -1). After the flow 374 or the flow 375, the timer is reset in the flow 376, the subroutine is ended, and the process returns to the calling source.

At the caller of the short circuit detection subroutine,
If the return value is data (1), add it and add it to the count value. If the return value is short circuit information (-1), it is a short circuit accident and it is not added to the count value, and the alarm lamp is turned on. Perform processing. In this way, even if the signal cable 328 is short-circuited, it is not recognized as erroneous data, and by immediately issuing an alarm, the amount-related information is not seriously lost.

In this embodiment, as the money amount related information,
The renting signal from the inter-mountain ball lending machine input to the terminals 6A and 6B of the connector 32b of the platform management device 3 is shown, but the prize ball count input to the terminals 9A and 9B of the connector 32b of the platform management device 3 is shown. Award ball signal from the machine, connector 22 of the island management device 2
The rental machine signal from the general ball rental machine, which is input to the terminals 2A and 2B of b, the terminals 1A and 1B of the connector 22b of the island management device 2
The safe signal from the depositing device, which is input to, is also money amount related information, and has the same input circuit.

[0065]

Since the present invention is configured as described above, it has the following effects.

Since the output of the disconnection detection circuit for monitoring the level of the input terminal is directly input from the input port different from the input signal, even if the signal cable is disconnected, it can be detected immediately.

It is not necessary to judge a short-time disconnection state, which occurs when the connector of the signal cable is attached or detached or when the connector is not properly connected, as an information pulse, and the reliability of the amount-related information is improved. .

It is possible to detect a short circuit of the signal cable, eliminate the loss of the money amount related information, and increase the reliability of the money amount related information.

Since the important information relating to the profit and loss of the store for the gaming hall can be collected without any error or loss, the gaming hall can be operated efficiently, and unnecessary work such as data correction and repair can be omitted.
