Description

The present invention relates to a gaming machine management device such as a pachinko machine.

(Prior art and its problems) In the connection relationship between the conventional management device and each gaming machine, the line (data transmission path) is directly connected, and the wiring extended from the management device circulates in the game store for a long time. And it was connected to the corresponding game machine.

In addition, there are cases where dedicated wirings are required for various signals corresponding to the game information, and a plurality of wirings are extended from the management device to one gaming machine. .

Such a connection relationship not only leads to complicated wiring and is inconvenient for wiring work and maintenance management, but also because it is redundant, it is easy for noise such as disconnection accidents and radio waves to occur, which adversely affects accurate data collection.

Further, in a conventional game machine, for example, as disclosed in Japanese Patent Laid-Open No. 58-41584, the game is detected in order to detect fraudulent acts performed by a player using a magnet, electronic noise, or the like. Even if the fraud detection sensor that should be installed in the key part of the machine itself is unavoidable, even the fraud detection means as a circuit that appropriately processes the signal output from the fraud detection sensor is provided in the gaming machine itself. Therefore, the fraud detecting means as a usable circuit has been abandoned when the game machine is replaced.

The present invention aims to solve such problems.

(Means for Solving Problems) The gaming machine management device of the present invention is a gaming information detecting means (S0 to S4) for detecting the gaming state according to the development of a game and a gaming machine control means (10) for controlling the operation of the gaming machine. , 11, 16, 20, 26, 33, 42) and a plurality of gaming machines (2P1 to 2Pn), and a centralized management device that manages the plurality of gaming machines based on the gaming information from each gaming machine ( 110, 120, 130, 140, 150

Then, the control unit (50P1 which transmits the above-mentioned central control device and also receives the command from the central control device and transmits it to the gaming machine control means of the gaming machine.
~ 50Pn), the control unit is configured to have a fraud detection processing means (fraud detection circuit 57) as a circuit for processing the signal output from the fraud detection sensor arranged in the gaming machine. .

(Example) Hereinafter, the present invention will be described based on an example of a pachinko machine.

FIG. 1 and FIG. 2 are fraud detection sensors (S) for detecting fraud provided on a gaming machine as an example of game information detection means for detecting the game state according to the development of the game.
0) and a pachinko machine 2 having, as an example of a gaming machine control means for controlling the operation of the gaming machine, a gaming disabling means for disabling a game in the case of an illegal act.

This pachinko machine 2 has a roulette game device 4 in the center of the game board 3, a specific winning opening 5 above it, and a winning device below, and by slightly turning the operation dial 7 provided at the bottom of the front frame 6, The electric launch drive unit (motor in this embodiment) 11 of the hitting ball launching device 10 is turned on, and the launching punch 12
Oscillates intermittently.

The ball hit by the intermittent swing of the launching pestle 12 enters the game area of the game board 3 while being guided by the launch rail 13A and the guide rail 13B.

Then, when the specific winning opening 5 is won, the roulette game device 4 starts to operate, and the rotation of the roulette is stopped when a certain time has elapsed or when the stop button 4A is pressed.

If the number combination when the roulette game device 4 is stopped matches the predetermined combination, the winning rate to the winning device is increased.

On the launch rail 13A, by the action of the hit ball supply device 20,
The balls of the supply tray 8 are taken in one by one.

Therefore, the game disabling means as an example of the game machine control means is a device for prohibiting the power supply to the electric launch drive unit 11 of the hitting ball launching device 10, and prevents the shot ball hitting the game board 3 from jumping. Device, a device that prohibits the ball from the supply tray 8 by the hitting ball supply device 20, and the like.

FIG. 3 shows another example of the game machine control means, which is a pin which can be projected and retracted into the ball passage 14 of the guide rail 13B in order to prevent the shot ball hit from flying into the game board 3. 15 is provided, and the electromagnetic solenoid 16
This is an example of a passage blocking device configured to be driven by a return spring 17 and a return spring 17.

Reference numeral 18 in the drawing denotes a stay for attaching the solenoid 16 to the game board 3, and 19 denotes a front glass plate.

FIG. 4 is also another example of the gaming machine control means, which is an example of a supply stopping device configured to prohibit the ball from the supply tray 8 by the hitting ball supply device 20.

Reference numeral 21 in the drawing is a ball intake port communicating with the lower end of the supply tray 8, and 22 is a sliding plate which can be linearly reciprocated in a direction orthogonal to the passage of the ball intake port 21. 22 has a closing piece 23 for the ball inlet 21.

One end of the sliding plate 22 is engaged with one end of a bell crank 24, and an engaging rod 25 is provided at the other end of the bell crank. The engaging rod 25 engages with a link motion mechanism (not shown) connected to the ball shortage detecting mechanism 28 of the upper tank 31 so as to be disengageable.

When the balls in the upper tank 31 are insufficient, the link motion mechanism operates, the ball shortage sensor S4 operates, and the engagement rod 25 is disengaged from the link motion mechanism.
Goes down and Bell Crank 24 rotates counterclockwise.

Therefore, the sliding plate 22 is moved to the right, and the closing piece 23 of the sliding plate 22 is moved.
Closes the ball inlet 21 to block the inflow of balls.

On the other hand, in order to force the closing movement of the sliding plate 22 regardless of the amount of balls in the upper tank 31, the bell crank 24
An electromagnetic solenoid 26 is provided on the side opposite to.

The sliding plate 22 is driven by the electromagnetic solenoid 26 to the closed position of the ball inlet 21, and is returned to the open position by the return spring 27.

A more simple game disabling means than the passage blocking device or the supply stopping device is to prohibit the power supply to the electric firing drive unit 11 of the hitting ball launching device 10.

However, in this case, unlike the case of FIG. 3 or 4, it is necessary that the hitting ball launching device 10 has an electrical launching drive unit (motor) 11 as in this example.

The hitting ball launching device 10 is not limited to a type using a so-called motor as a drive source, and, for example, a rotary solenoid that intermittently reciprocates can be used.

Reference numeral 29 in the figure is a speaker provided on the front panel of the machine casing for transmitting specific information to the player.

Next, a fraud detection sensor (So) for detecting fraudulent activity arranged in a gaming machine will be described as an example of game information detecting means for detecting the gaming state according to the development of the game.

The types of fraudulent acts to obtain unfair prize balls include the method of using an external magnet, and the use of a spark writer (electronic writer, battery writer, electromagnetic writer, IC writer, etc.) to generate noise with a steep waveform, which results in a pachinko machine. There is a method of erroneously operating the electric control circuit of, and a method of keeping the opening and closing plate of the winning opening of the large-scale winning device of a pachinko machine open by hooking it with a piano or the like.

Therefore, the fraud detection sensor differs in its specific means depending on the type of these fraudulent acts.

In the first embodiment, the fraud detection sensor will be described as a magnetic sensor.

The upper tank 31 is provided above the back mechanism plate 30 of the pachinko machine 2, and the prize balls in the upper tank 31 are guided to the ball sheath case 34, which is a component of the prize ball discharging device 33, through the guide path 32. ,
The case 34 and the taxiway 32 are filled.

On the other hand, the winning balls flow down while rolling on an inclined guide shelf that forms the bottom surface of the collecting gutter 41 provided on the back surface of the game board 3, and enter the winning ball processing device 42.

The winning ball processing device 42 is tiltably disposed at the lower end of the guide shelf, and sends one winning ball flowing down on the guide shelf to the prize ball discharging drive unit 40.

The prize ball discharge drive unit 40 has a crank lever 39 that tilts by the weight of one prize ball, and the rear end of the crank lever 39 is connected to the ball sheath case 34 via an interlocking rod 38.

As a result, the ball casing 34 tilts for each winning ball and drops a predetermined number of prize balls onto the damper 35A of the guide path 35.

The prize ball flowing down the lead-out path 35 collides with the prize ball bell 36 and makes it ring, and then is discharged to the supply tray 8 on the front surface of the pachinko machine 2 through the discharge port 37.

The back of the collecting gutter 41 on the back side of the pachinko machine 2 or the game board 3
A magnetic sensor S0 as a fraud detection sensor for detecting fraudulent activity by the external magnet 43 is provided on the back surface side of the player at a position corresponding to each winning chucker.

As the magnetic sensor, a Hall element, a so-called SMD (trade name), a semiconductor magnetic sensitive element such as a magnetic resistance element, a reed switch, or the like can be used. In this embodiment, it is a Hall element.

FIG. 5 shows an example in which a magnetic sensor S0 functioning as a fraud detecting sensor is attached to the rear face of the collecting gutter 41 as an example of the game information detecting means.

The mounting position of this magnetic sensor S0 is a position where the magnetic force can be sensed when the external magnet 43 is brought close to the vicinity of the specific winning opening 5 as the winning chucker from the outside of the front glass 19, that is, immediately after the specific winning opening 5. On the top.

Reference numeral 44 in the figure is a winning ball guide hole provided on the game board 3, 45 is a guide frame for guiding the prize ball into the collecting gutter 41, and S1 is a prize as another game information detecting means provided in the guide frame 45. It is a ball sensor, and the winning ball pushes the pressing piece of the sensor S1 and falls downward.

The collecting gutter 41 is made of synthetic resin, and the distance between the rear surface of the collecting gutter 41 and the front glass plate 19 is usually about 65 mm.

However, in this example, since the Hall element having a relatively high sensitivity using the current magnetic effect of the semiconductor is used as the magnetic sensor S0, even if it is not provided on the front side of the game board 3 as in the case of the reed switch, The presence of the external magnet 43 can be detected.

The magnetic sensor S0 is provided for the specific winning opening 5 because the value of the winning of one ball is the specific winning opening 5 as a chucker that operates the roulette game device 4 and other ordinary winning openings that are not. The reason is that the former has a much higher game value, and can be provided at another winning opening if necessary.

In FIG. 6, a centralized management device for managing a plurality of gaming machines based on the gaming information from each gaming machine will be described.

Reference numeral 1 in the figure indicates an island facility of a pachinko game store which is composed of a plurality of pachinko machines 2P1 to 2Pn, and a control computer system shown on the left side of the figure performs centralized management.

And has a game-inhibition release key 1316 for releasing the table which has become inoperable.

 The transmission control device 300 will be described with reference to FIG.

This transmission control device 300 includes an address generating circuit 80 for creating a circulating address (a circulating address for pachinko machines 2P1 to 2Pn) similar to the address generated from the CPU 110, and a circulating circuit based on the address from the generating circuit. Selectively, each pachinko machine selection signal line 65P1 to 65Pn (9th

And a control circuit 86.

The reception circuit 83 and the transmission circuit 84 each have a built-in memory addressed for each pachinko machine base for each type of information, and each pachinko machine base and the computer system are connected via these memory groups. Send and receive information between.

As the game information received and collected by the transmission control device 300,
In addition to the number of winning balls, the number of balls to be hit, the number of balls to be replenished, the number of balls shortage, etc. for each pachinko machine 2P1 to 2Pn, fraud as an output signal from the fraud detection sensor installed in each gaming machine There is information and the like, and the commands to be transmitted include a forced game disabling command and a supply command.

Based on the information received by the transmission control device 300 and the information input from the keyboard 130, the CPU 110 causes the display (CRT) 150 to detect a fraudulent table, a stop table, an additional supply completion stand, a stop release stand, etc. It displays necessary information such as the machine number and causes the printer 140 to create a hard copy such as sales totals, and controls a forced game disable command and a replenishment command for the pachinko machine of the corresponding machine number.

 The outline of the operation at the time of reception will be described below.

First, the address generation circuit 80 cyclically generates an address for each pachinko machine, and the terminal designating circuit 81 sequentially supplies a selection signal to each pachinko machine base in accordance with this address.

Then, various game information (number of winning balls, number of hit balls, number of replenishing balls, shortage of balls, magnetic detection, etc.) from the game information detecting means of the selected pachinko machine is received through the information transmission line 210. Added to each of the memory groups in 83.

At this time, to these memory groups, the same address as that of the above-mentioned pachinko machine is added from the address generation circuit 80 via the address selection circuit 85, and is stored in the designated address. .

Therefore, the game information detected by each pachinko machine is stored in the memory in the receiving circuit 83 for each pachinko machine and for each information.

The game information stored in this way is output to the system bus 170 on the computer system side at the timing designated by the timing control circuit 86, and the CPU 110
Given to.

When there is magnetic detection, the CPU 110 designates the I / O port of the alarm 160 in the central control room and activates the alarm 160.

This alarm 160 is an alarm stop key 131 on the keyboard.
Continues to ring until 4 is pressed.

 Next, an outline of the operation when transmitting the control command will be described.

The CPU 110 supplies data including address information to the address selection circuit 85, and this data is supplied to the transmission circuit 84 at the timing designated by the timing control circuit 86.

The data given from the CPU 110 includes address information and a control command, and therefore, the control command is stored in the memory area allocated to the pachinko machines 2P1 to 2Pn which is the transmission destination.

Then, next, under the control of the timing control circuit 86, when the address selection circuit 85 selects the address generated by the address generation circuit 80, the control instruction stored in the memory is read out, through the information transmission line 210, It is given to a predetermined pachinko machine.

Therefore, for example, when a magnetic sensor functioning as a fraud detecting sensor as one example of the game information detecting means of a certain pachinko machine detects magnetism, that is, fraudulent activity, the CPU 110 sends a game disabling instruction to a predetermined memory in the transmission circuit 84. The information is stored in the address, and when the terminal designating circuit 81 designates the pachinko machine in which the fraudulent act was performed, this game disabling instruction is sent to the information transmission line 210.

When the game disabling command is sent, the game machine control means of the pachinko machine of the corresponding unit number, in the case of this example, the game disabling means (the firing drive operation prohibition circuit, the electromagnetic solenoid 16,
26 etc.) and the game disabling means continues to operate until the game disable release key 1316 of the keyboard 130 is pressed.

Also, in this case, the display 150 preferentially displays that there has been a misconduct and the unit number of the misconduct table.

When it is desired to put the specific pachinko machine base into the game-disabled state, the machine number is designated by the ten keys 135 and the game-disabled key 1315 is pressed.

Next, a more detailed description will be given with reference to FIGS.

First, a control unit that is provided so as to be connectable corresponding to each gaming machine will be described. Control unit (50P1 to 50Pn)
Is for receiving information from the game information detecting means of the gaming machine and transmitting it to the centralized management device, and also for receiving a command from the centralized management device and transmitting it to the gaming machine control means of the gaming machine.

By interposing a control unit like this between the pachinko machine and the management device in a freely connectable manner, the wiring that tends to be redundant can be reasonably consolidated, and the room for picking up noise such as radio waves can be reduced accordingly. .

Further, in this embodiment, the control units 50P1 to 50Pn are
As shown in the figure, it is provided on the side of the island facility 1 above the gaming machine so as not to be unnecessarily distant from the gaming machine while being separated from the gaming machine.

By arranging the control units 50P1 to 50Pn for each pachinko machine on the island equipment 1 side in this way, the control unit 50P1 to 50Pn can be left as it is when the pachinko machine is replaced, and it is not necessary to replace it. , Has the advantage of cost reduction. Further, the reason why the game machine is separated into a position that is not too far from the game machine is that the wire length between the game machine and the control unit is shortened to make it difficult for the line to pick up noise.

The reference numeral 49 in the figure is a replenishing device also provided on the side of the island facility 1 for each pachinko machine, counting balls sent from the replenishment gutter 47 through the replenishment chute 48 based on the replenishment command. A predetermined amount is supplied to the upper tank 31 of the pachinko machine.

The replenishment device 49 is provided with a replenishment sensor S3 for counting the number of balls replenished from the replenishment device to the upper tank 31.

In this pachinko machine, a magnetic sensor that functions as the above-mentioned fraud detection sensor as an example of game information detection means.
In addition to S0, a winning ball sensor S1, a replenishment sensor S3, a ball shortage sensor S4, a driving ball sensor S2 for detecting a driving ball falling from the ball receiving box 46, and the like are provided.

Each control unit (50P1 to Pn) has a touch contactor 51 of the operation dial 7, a firing drive unit (hereinafter simply referred to as a "motor") 11 of a hitting ball launching device, a magnetic sensor S0, and a winning ball sensor S.
1, a driving ball sensor S2, a replenishment sensor S3, and a ball shortage sensor S4 are connected.

In FIG. 9, the illustrated control unit 50P1 is a fraud detection processing circuit 57 as a motor control circuit and a circuit for processing a signal output from a fraud detection sensor provided in the gaming machine.
It also has a supply control circuit.

The motor control circuit includes a motor control relay circuit 54 that switches the power supply of the motor 11, a touch circuit 52 that turns on the motor control relay circuit 54 when the player touches the touch contactor 51, and the touch circuit 52. Relay circuit

Further, the replenishment control circuit has a timer circuit 59 for operating the replenishment device 49 and a photocoupler 58 for coupling the timer circuit 59 with a transmission system.

Referring again to FIG. 9, each pachinko machine P1 to
The information transmission line 210 common to 2Pn includes several data transmission lines 60, one forced game disabling line 61, one supply control signal line 62, and one power supply line 63 (24V).
And one regression line 64.

In addition, the terminal designation line 220 includes selection signal lines 65P1 to 65Pn for individually selecting each of the pachinko machines P1 to 2Pn.

In this example, since there are five sensors S0 to S4, the number of data transmission lines 60 is also five, and the lines 60 to 63 common to each pachinko machine are eight in total. Therefore, it is characterized in that the number of lines is smaller than in a system in which a data bus is arranged and ordinary electric wires are used.

One end of each of the sensors S0 to S4 is connected to the data transmission line 60 on a one-to-one basis for each control unit, and the other ends of these sensors are made common by a common bus line 66 to select signal lines 65P1 to 65P1. It is connected to one of the 65Pn.

The light emitting diodes of the photocouplers 55 and 58 are connected between the control signal lines 61 and 62 and the common bus line 66, respectively.

The phototransistors of the photocouplers 55 and 58 are connected to the trigger input terminals of the timer circuits 56 and 59, respectively.

FIG. 10 is a block diagram showing details of the fraud detection processing circuit 57 and the motor control circuit.

Explaining the motor control circuit, when the player touches the touch contactor 51 of the operation dial 7, the touch circuit 52 responsively generates a motor operation signal.

The motor control relay 54 is energized through the touch driver, and its contact 54 'is turned on.

As a result, the motor 11 of the hitting ball launching device 10 is started.

As shown by a broken line in the drawing, an operation switch 52 'that is turned on when the operation dial 7 is rotationally displaced can be used instead of the touch switch circuit.

Reference numeral 67 in the figure is a constant voltage circuit for the motor control circuit.

In the signal selection circuit 53 inserted between the touch driver and the motor control relay 54, the fraud detection processing circuit 57 detects fraudulent activity by a magnet or the like, and a centralized management computer gives a game disable command to the line 61. At this time, the prohibition operation, that is, the motor operation signal from the touch circuit 52 or the operation switch 52 'is prohibited from being applied to the motor control relay 54 so that the motor 11 of the hitting ball launching device 10 does not operate.

The signal selection circuit 53 can be configured using, for example, an inverter and an AND gate, or a switching element.

When the game disabling means as the game machine control means is the electromagnetic solenoids 16 and 26 (FIGS. 3 and 4), a control relay circuit dedicated to the game disabling means is provided separately from the motor control relay 54. It may be configured such that it is energized while the timer 56 is set.

Next, referring to FIG. 10, a fraud detection processing circuit 57, which is a circuit that appropriately processes a signal from the fraud detection sensor provided in the gaming machine, will be described.

In the figure, reference numeral 68 is a positive constant voltage circuit, 69 is a negative constant voltage circuit, and 70 is an offset adjustment circuit for the magnetic sensor (Hall element) S0.

The offset adjusting circuit 70 produces a reference voltage for compensating the unbalanced voltage of the Hall element S0 based on the voltages from the positive and negative constant voltage circuits 68 and 69.

Reference numeral 71 is an amplifier that amplifies the output from the hall element S0 as a fraud detection sensor provided in the gaming machine, and has an amplification factor adjusting means 72.

Reference numerals 73 and 74 represent the Hall voltage VH obtained from the amplifier 71.
Is a predetermined reference voltage VA, VB whose polarities are opposite to each other.
Reference numerals 75 and 76 are reference voltage sources for providing the reference voltages VA and VB.

The reason why the two comparators are provided in this way is that the Hall element is an element whose output voltage exhibits a so-called linear function change with respect to the magnetic field and has magnetic pole discrimination capability.

In this embodiment, the output of the amplifier 71 is input to the inverting input terminal of the first comparator 73 and the non-inverting input terminal of the second comparator 74, and the reference voltage VA of the first comparator 73 is added, Reference voltage VB of the second comparator 74
Is negative, and both sizes are the same.

The output terminals of the first comparator 73 and the second comparator 74 are commonly connected, and this output terminal is connected to one of the transmission lines 60 via the output driver 77.

Now, as shown in FIG. 5, when an illegal act of bringing the N pole of the external magnet 43 closer to the front glass plate 19 is performed, the external magnet 43 is
Is applied to the Hall element S0, and the Hall voltage having a magnitude depending on the magnitude of the magnetic force acting on the Hall element S0 is used as a signal for detecting that an illegal operation has been performed. It is generated, that is, output from the element S0.

Here, it is assumed that a positive Hall voltage is generated by bringing the N pole of the external magnet 43 closer.

This positive Hall voltage is output to VH through the amplifier 71.
, And the inverting input of the first comparator 73,
This is the non-inverting input of the second comparator 74. The comparison reference voltage VA in the first comparator 73 is positive, and the comparison reference voltage VB in the second comparator 74 is negative.

Therefore, when the level of the Hall voltage VH obtained through the amplifier 71 exceeds the reference voltage VA, the negative comparator match signal is generated from the first comparator 73.

As a result, a fraud detection signal is generated on the transmission line 60 via the driver 77.

Next, when the S pole of the external magnet 43 is brought closer to the front glass 19, the polarity of the Hall voltage generated from the Hall element S0 is reversed from that when it is the N pole, and the polarity becomes negative.

Therefore, when the level of the Hall voltage VH obtained through the amplifier 71 exceeds the negative reference voltage VB, the negative comparator match signal is generated from the second comparator 74.

The subsequent operation is the same as that when the negative comparison match signal is generated from the first comparator 73.

After all, either the north pole or the south pole of the external magnet 43 is a front glass.
Even when it is brought closer to 19, the illegal action is immediately detected by the computer, and the drive motor 11 of the hitting ball launching device 10 is stopped based on the command control from the central control room.

And a preset counter PC for stepping at a predetermined timing based on the received data, and an integrated value thereof is stored in the memory M.
And a memory control circuit MC for moving the contents of the memory M to the preset counter PC and the system bus 170.

The memory control circuit MC includes, for example, a memory (RAM) having a 1-bit storage area for each pachinko machine, and a Q of the memory.
It has an inverter connected to the output terminal, and an AND gate having three inputs: the output of the inverter, the data latch output from the interface 82, and the count lock from the timing control circuit 86.

On the other hand, the non-integration type receiving circuits 834 and 835 are composed of a memory M dedicated to the data, a buffer gate B, a memory control circuit
It consists of MC and there is no preset counter.

Next, the transmission circuit 84 (FIG. 6) is a game disabling command circuit.
841 and a replenishment command circuit 842.

Both circuits 841 and 842 are a memory M dedicated to the data, a memory control circuit MC, and a command flip-flop, respectively.
FF1 and FF2, and AND gates G1 and G2 for adjusting command timing provided between the flip-flops FF1 and FF2 and the memory M.
It consists of and.

Each memory M of the transmission / reception circuits 83, 84 (Fig. 6) has a data storage area for each pachinko machine, and its address corresponds to the address created by the CPU 110 and the address generation circuit 80 (Fig. 6). It is designed so that

The address selection circuit 85 (Fig. 6) is an address counter.
A buffer gate 851 for giving the address of 803 to the data bus AD2 of the transmitting / receiving circuits 83, 84, a latch circuit 852 for storing the address and data from the CPU 110, and a transmitting / receiving circuit for the address and data stored in the latch circuit 852. 8
Buffer gate to feed 3, 84 address bus AD2
It consists of 853.

The timing control circuit 86 (FIG. 6) is a frequency division counter 80.
Decoder 861 that decodes the count value of 2 and outputs (timing signal) to one of output terminals "0" to "7", and "3", "4", "5", "6" of the decoder OR gate with number 4 as input
It consists of 862.

The output of the decoder 861 makes one cycle from "0" to "7" while the address counter 803 is incremented by one.

The "0" output of the decoder 861 serves as a load signal for the latch circuit 820 and the memory M of the integrating type receiving circuit, and as a reset signal of the flip-flop FF.

The "1" output is the preset counter of the integrating receiver circuit
Works as a count clock for the PC.

The "2" output serves as a write signal for the memory M of the integrating type receiving circuit.

The "3" to "6" outputs, that is, the output of the OR gate 862 functions as a signal for switching the buffer gate of the address selection circuit 85.

The "7" output serves as a condition signal for transmitting the contents of the memory M of the non-integrating type receiving circuit.

(1) Operation during data collection First, the oscillator (OC) 801 is constantly oscillating since the power was turned on, and the output thereof causes the counter 802 to step up.

The count value of the counter 802 is added to the decoder 861,
The decoder 861 decodes the count value and outputs various timing control signals, and the output of the most significant digit of the counter 802 is added to the address counter 803.
Step 03.

Therefore, while the address counter 803 is incremented by 1,
The eight kinds of timing control signals from "0" to "7" output from the decoder 861 make one cycle.

Data is transmitted / received to / from one pachinko machine while the output of the decoder 861 makes one cycle, and every time the address counter 803 is incremented, the machine number of the pachinko machine to which data is transmitted / received is updated. To be done.

More specifically, the count value of the counter 803 is the scanner, that is,
It is added to the decoder 810 of the terminal designating circuit 81. For example, when the count value of the address counter 803 is 0, the 0th output of the decoder 810 becomes H level and the sweep driver 811
DR1 is turned on and the 0th series (pachinko machine 2P1) is selected.

Therefore, at this time, if the winning ball sensor S1 in the pachinko machine 2P1 is on, a current flows through the path of the power supply Va, the winning ball sensor S1, and the sweep driver DR1, and the photocoupler P1 of the interface 82 is turned on. .

When the 0th output (load signal) of the decoder 861 of the timing control circuit is at the H level, the detection of the winning ball is stored in the memory portion for the winning ball sensor S1 of the interface latch circuit 820, and the latch output is H level. Become a level.

Further, when the load signal is at the H level, the output of the OR gate 862 is naturally at the L level, so the buffer gate 851 is activated, and the address generated by the address counter 803 (indicating 0s) is Buffer gate 851,
Memory MC of winning ball receiving circuit 831 via address bus AD2
Given to.

Since the memory control circuit MC gives this address to the winning ball memory M as it is, the stored contents of the storage area assigned to the 0s of the winning ball memory M are added to the preset counter PC from the output terminal Q of the memory M.

At this time, the content of the winning ball memory M is obtained by accumulating the number of winning balls in the 0s up to the previous cycle. At this time, since the load signal is at the H level, the memory control circuit
The MC gives this load signal (H level) as it is to the preset counter PC as a preset enable signal, and the preset counter PC presets the accumulated value of the number of winning balls in the 0s up to the previous cycle through the data bus DB1.

Next, when the frequency division counter 802 is incremented by one and the load signal of the decoder 861 of the timing control circuit 86 falls,
At the same time, the first output of the decoder 861, that is, the count clock rises, and this counter clock is added to the 3-input AND gate in the memory control circuit MC.

At this time, in the memory in the memory control circuit MC, the 0th storage area is designated by the address from the address counter 803.

By the operation of the 3-input AND gate in the memory control circuit MC, the memory control circuit MC adds a count-up clock to the preset counter PC when the corresponding latch output D1 of the latch circuit 820 of the interface 82 is at H level. Count up the preset counter PC by 1.

Next, the frequency division counter 802 is incremented by one and the decoder 861
When the count clock of the memory controller falls, the second output (write signal) of the decoder 861 is simultaneously output from the memory control circuit MC.
This write signal is added to the winning ball memory M through the memory control circuit MC.

At this time, the content of the preset counter PC has been incremented by 1 from the previous cycle, so the storage area assigned to the 0th row of the winning ball memory M has been incremented by 1 from the previous cycle. The number of winning balls is
It is stored through the data bus DB2.

At this time, if the latch circuit 820 does not store the generation of the winning ball detection signal, the stored content of the winning ball memory M is the same as the previous cycle.

Subsequently, when the second output of the decoder 861 falls, the third output, the fourth output, the fifth output and the sixth output of the decoder 861 sequentially rise, and the output of the OR gate 862 becomes H level during that period.

Therefore, during that time, the buffer gate 851 is closed and the buffer gate 853 is activated.

On the other hand, the CPU 110 periodically outputs to the system bus 170, as part of the data, an address for designating a pachinko machine, and this address is the address selection circuit 85.
It is stored in the latch circuit 852 (FIG. 6).

And the OR gate of the timing control circuit 86 (FIG. 6)
When the output of 862 becomes H level, the address stored in this latch circuit 852 is given to the memory control circuit MC via the buffer gate 853, and the memory control circuit MC uses this as a read address in the winning ball memory M. give.

Therefore, from the address 0 of the winning ball memory M (the address specified by the CPU 110 and the address specified by the address counter 803 do not necessarily have to match, but if the CPU 110 specifies the address 0, the winning ball The accumulated winning ball numbers in the 0's (from the address 0 of the memory M) are read out to the data bus DB1, and this information is put on the system bus 170 via the buffer gate B and taken into the processor.

The operation of collecting data about the number of driven balls and the number of supplied balls, that is, game information, of each of the pachinko machines 2P1 to 2Pn (Fig. 6) is the same as the case of collecting data about the number of winning balls.

Next, the operation of the non-integration type reception circuit
835 will be described as an example.

The signal from the fraud detection circuit 57 is status information indicating the state of each of the pachinko machines 2P1 to 2Pn (Fig. 6) like the information about the shortage of balls, and is not integrated data such as the number of winning balls. A preset counter for accumulating is not provided, and the memory M functions as a status flag corresponding to each pachinko machine 2P1 to 2Pn.

The selection of the pachinko machines 2P1 to 2Pn is performed by the scanner, that is, the terminal designating circuit 81 as in the case of collecting the winning balls.

When an illegality detection signal is generated from the circuit 57 when the scanner, that is, the decoder 810 of the terminal designating circuit 81 selects, for example, the 0s (pachinko machine 2P1), the decoder 861 of the timing control circuit 86 outputs the load signal. At the rising timing, the illegality detection signal is stored in the latch circuit 820 of the interface, the corresponding output of the latch circuit 820 becomes H level, and is added to the memory control circuit MC.

At this time, the memory control circuit MC is given addresses in the 0's (pachinko machine 2P1) from the buffer gate 851, and the memory control circuit MC gives the addresses in the 0's to the memory M as read addresses.

Then, at the timing when the decoder 861 outputs the second output, that is, the write signal, the memory control circuit MC applies the write control signal to the memory M and outputs the corresponding output D5 of the latch circuit 820 by 1 bit. Add as data input of.

Therefore, if the 0s detect fraud, the contents of the addresses corresponding to the 0s of the memory M become H level.

Then, when the 2nd output of the decoder 861 falls, after that, the 3rd output, 4th output, 5th output and 6 of the decoder 861
Output sequentially rises, and the output of the OR gate 862 becomes H level during that period. Therefore, during that time, the buffer gate 851 is closed and the buffer gate 853 is activated.

While the buffer gate 853 is activated, the CPU 110
System bus 170, latch circuit 852, address bus AD
A read address is given to the memory control circuit MC via 2 and the content of the memory M is read out via the buffer gate B.

When the CPU 110 detects a fraudulent activity in the first group, it activates the alarm 160 in the control room and notifies the fact.

(2) Control command operation to the pachinko machine When the CPU 110 detects a fraudulent act or a ball shortage (game information) for any of the pachinko machines, it instructs the appropriate game machine control means of the pachinko machine to disable the game. Or issue a replenishment command.

Hereinafter, a case of issuing a game disabling instruction will be described.

First, when the misconduct information is transmitted from the game information detecting means of a certain pachinko machine through the control units 50P1 to 50Pn (Fig. 8), the CPU 110 sends a game disabling signal and misconduct through the system bus 170. The information indicating the unit number of the pachinko machine that has the error is given to the latch circuit 852 of the address selection circuit 80.

Then, these pieces of information are added to the memory control circuit MC via the address bus AD2 when the buffer gate 853 is activated by the decoder 861 of the timing control circuit 86.

As a result, the memory control circuit MC gives the memory M the machine number of the pachinko machine in which the fraudulent activity has occurred, sets the data output to the H level, and applies the write control signal.

As a result, the designated address in the memory M becomes H level, and it is stored that the corresponding pachinko machine should be given a game disabling instruction.

Specifically, for example, when a game disabling instruction is given to the 0s, the 0th address of the memory M becomes the H level.

Then, when addresses in the 0s are designated by the address counter 803, the output of the AND gate G1 rises at the timing when the decoder 861 outputs the load signal,
Flip-flop FF1 is set.

As a result, the transistor 822 is turned on and the line 61 is connected to the power supply, that is, the game disable signal is generated on the line 61.

At this time, since the 0s are selected by the scanner, that is, the decoder 810 of the terminal designating circuit 81, the photocoupler 55
And the timer circuit 56 is set (FIG. 9).

Then, the flip-flop FF1 is reset at the timing when the decoder 861 raises the seventh output.

However, the timer time of the timer circuit 56 is preset so as to have at least the time width required for one round of the scanner, that is, the terminal designating circuit 81.

Therefore, the inoperability release switch 1316 of the keyboard 130
As long as is not pressed and the game disabling instruction in the 0s (2P1) in the memory M is not cleared, the timer circuit 56 is reset every time the scanner, that is, the terminal designating circuit 81 makes one cycle, and the timer time Updates are made.

That is, the signal selection circuit 53 (FIG. 9) in the control unit 50P1 in the 0s (2P1) is continuously kept in the prohibited operation state by the output of the timer circuit 56, and the power supply to the motor control relay 55 is blocked. (Fig. 9).

As a result, the hitting ball launching device 10 of the pachinko machine is stopped and the game becomes impossible.

In case of ball shortage detection, the photo coupler 58
The light emitting diode (Fig. 9) emits light, the base current flows through the transistor 60 for the time width set by the timer circuit 59, the replenishment electromagnet of the replenishment device 49 operates during that time, and a predetermined number of pachinko balls are placed in the 0s. Is replenished. And the decoder
The flip-flop FF1 is reset at the timing when the 861 rises the 7th output.

The OR gate 812 is a scanner, that is, the decoder 81 of the terminal designating circuit 81, when the CPU 110 is writing a control command.
0 is for preventing selection of a pachinko machine, and the decoder 810 of the scanner 81 is enabled when the output of the OR gate 812 is at L level.

In FIG. 9, switches SW1 and SW2 are manual switches for enabling only the operation of supplying each pachinko machine and forcibly disabling the game even when the computer system fails.

In the above embodiment, when the pachinko machine base is disabled due to a fraudulent act, the pachinko machine base is disabled to play by a cancellation command from the computer, but not directly from the computer, the clerk directly A release switch can be provided in the game disabling means so that the game disabling can be released by a manual operation.

Further, in the above embodiment, in order to continue operating the game disabling means for an appropriate period, a timer circuit 56 (9th time period) that continues for a certain period of time after receiving the game disabling instruction via the photo coupler 55.
However, other arbitrary circuit means can also be used.

For example, instead of the photo coupler 55 and the timer circuit 56,
A flip-flop is provided in each control unit 50P1 to 50Pn, and its set input terminal is connected to the disabling line 61.

On the other hand, in addition to the lines 61 and 62, a control line for a cancellation command is added, and this additional line is connected to a game cancellation command transmission circuit configured similarly to the transmission circuit 84.

Then, the reset input terminal of each flip-flop is connected to the release command line, and the set output terminal of the flip-flop is connected to the inhibition input terminal of the signal selection circuit 53.

That is, the scanner, that is, the pachinko machine selected by the terminal designating circuit 81, if there is a game disabling command on the line 61, the flip-flop is set and the signal selecting circuit 53 inhibits operation, and the game disabling cancellation command is given to the additional line. If so, the flip-flop may be reset so that the inhibition operation of the signal selection circuit 53 is released.

According to this structure, even if the signal on the line 61 is interrupted while the address of the pachinko machine circulates, the game disable state can be continued until the game disable instruction is issued from the keyboard.

Next, a description will be given of means for detecting fraudulent activity in which the opening / closing plate of the winning opening of the variable winning device is left open with a piano wire or the like.

In FIG. 12 and FIG. 13, reference numeral 90 in the drawing is an example of the variable winning device attached to the front surface of the game board 3 of the pachinko machine, and the winning opening 92 thereof is opened and closed by the opening / closing plate 91. .

The opening / closing plate 91 is predetermined, for example, on the condition that a ball has entered the specific winning opening 5 (FIG. 1) or on the condition that the rotated roulette game device 4 has stopped at a combination of numbers for medium hit or big hit. Keep open for only 10 seconds or 30 seconds.

The winning opening 92 is larger than a normal winning opening, and when the opening / closing plate 91 is opened, the winning rate is extremely improved.

Therefore, if the open / close plate 91 is forcibly held in an open state by a piano wire or the like, an unreasonably large number of prize balls can be obtained.

FIG. 14, FIG. 15 and FIG. 16 are different examples of circuits for detecting such fraud.

The fraud detection circuit 57 shown in FIG.
Since the opening / closing plate 91 is forcibly opened within the period in which the opening / closing plate 91 should be closed, this is used for determining the presence or absence of fraud.

Reference numeral 93 in the figure denotes a photoelectric type opening / closing plate sensor (illegal detection sensor) provided in the variable winning device 90 to know the opening / closing state of the opening / closing plate 91. The open operation confirmation signal 93A is generated.

This open operation confirmation signal 93A is an AND gate of the fraud detection circuit 57.
One of 94 inputs.

The other input terminal of the AND gate 94 has a variable winning device 90.
From the fluctuation control circuit 95 that opens and closes the opening / closing plate 91, the complement (inversion signal) of the operation signal 95A for opening the opening / closing plate 91 is input.

The variation control circuit 95 for opening and closing the opening / closing plate 91 of the variation winning device 90 is a flip-flop 952 that is set when the special switch 951 is turned on, that is, when the above-described jackpot condition is satisfied, and this set. A timer 953 that is triggered by the output and resets the flip-flop 952 after a certain time, and when the flip-flop 952 is set and counts all winning balls detected by the winning sensor S1 and reaches a predetermined number, the flip-flop 952 is set. A driver 955 that opens the opening / closing plate 91 only while the N-ary counter 954 to be reset and the flip-flop 952 are in the set state.
Have and.

Therefore, the opening / closing plate 91 is set to the timer time of the timer 953, for example, 30
It will be closed depending on whether the second arrives or the counter 954 counts up a predetermined number of winning balls, whichever comes first.

AND that inputs the complement of the operation signal 95A from the fluctuation control circuit 95 and the opening operation confirmation signal 93A from the opening / closing plate sensor 93 to two inputs
The gate 94 produces an output when the opening / closing plate 91 is opened during a period in which the opening / closing plate 91 of the variable winning device 90 should be closed during normal operation.

Reference numeral 96 is a flip-flop set by the output of the AND gate 94, and the set output is taken out as a fraud detection signal.

Reference numeral 97 is a timer, which is started by the set output of the flip-flop 96, and after a certain time, the flip-flop 96
To reset the fraud detection signal. This is so that the computer can be controlled to operate the game disabling means only while the fraud detection signal is generated in the fraud detection circuit 57.

Reference numeral 98 is a reset switch for resetting the flip-flop 96, for example, in conjunction with the operation of the lock on the front frame of the pachinko machine, the flip-flop 96 is reset when the clerk opens the front frame with the key. To do.

The fraud detection circuit of FIG. 15 detects fraudulent activity by discriminating this because the open time of the opening / closing plate 91 becomes longer than the regular maximum time, for example, 30 seconds, in case of fraudulent activity. It is a thing.

Reference numeral 101 in the figure is an AND gate that inputs the opening operation confirmation signal 93A from the opening / closing plate sensor 93 and the output signal from the oscillator 100, and the reference numeral 103 is a counter as a time comparator, which is an up counter or a down counter. Composed of counters.

The counter 103 counts the pulses from the oscillator 100 sent through the AND gate 102 while the opening / closing plate 91 is opened, that is, while the opening operation confirmation signal 93A is generated,
Count up or down the contents.

The delay circuit 102 produces an output and resets the counter 103 when a certain time has elapsed after the falling of the opening operation confirmation signal 93A.

Therefore, in the normal case, since the opening / closing plate 91 of the counter 103 is opened and closed for the maximum time period, the counter 103 is reset by the reset signal generated from the delay circuit 102 and no output is generated.

However, if the opening / closing plate 91 is kept open for a long time exceeding the predetermined maximum time limit, the delay circuit 102 does not generate the reset signal forever.

Therefore, the counter 103 continues to count the pulses from the gate 101, and the content reaches the value set by the setter 104. Therefore, an output is generated in the counter 103, the flip-flop 96 is set, and a fraud detection signal is generated.

The fraud detection circuit in FIG.
The number of winning balls that can enter the variable winning device 90 when the player opens for a certain period of time is a time constraint or counter 954 (Fig. 14).
From the existence of the above, it is noted that the upper limit is naturally determined, and when the number of winning balls larger than the upper limit is detected, it is determined that this is due to fraudulent activity.

Reference numeral 105 in the figure is a counter that counts detection signals from the winning ball sensor S1 that responds to the winning balls that have entered the variable winning device 90 and the like, and when the opening / closing plate 91 is closed, as in the case of FIG. The reset signal obtained from the opening / closing plate sensor 91 via the differentiating circuit 106, that is, the falling differential of the opening operation confirmation signal 93A, resets.

Normally, when the actuation signal 95A disappears, the opening / closing plate 91
Also, since the counter 105 also closes, the counter 105 produces no output.

However, when the opening / closing plate 91 does not close even if the operation signal 95A disappears, a reset signal is not generated in the differentiating circuit 106, so the counter 105 counts the number of winning ball detection pulses generated from the winning ball sensor S1. Continuing, the contents of the setting device 107
It reaches the upper limit of the number of winning balls set in.

Therefore, an output is generated in the counter 105, the flip-flop 96 is set, and a fraud detection signal is generated.

In addition, depending on the type of the variable winning device, there is a type in which the opening / closing plate is opened / closed only by the weight of the ball, and if the opening / closing plate is continuously opened illegally, the balls are accumulated in the winning opening. In the case of such a type, it is also possible to detect fraud by comparing the stationary or passing time of the ball staying at the winning opening with that in the normal case.

Although the pachinko machine has been described as an embodiment of the present invention, the present invention is not limited to a pachinko machine as long as it is a gaming machine that transmits and receives data between the management device and the control unit.

(Effect of the invention) As described above, the present invention separates the fraud detecting means from the gaming machine, receives the information from the gaming information detecting means of the gaming machine, transmits the information to the centralized management device, and the command from the centralized management device. It is incorporated into a control unit that receives and transmits to the gaming machine control means of the gaming machine, and this control unit is arranged on the island facility side above the gaming machine so that it can be connected between the gaming machine and the central control device freely. Because of the interposition, when replacing the game machines installed in the island equipment,
Unlike the conventional redundant wiring that is randomly connected between the central management device and each gaming machine, the processing of the wiring between the central management device and the central management device is performed by the control unit so that the upper portion of each gaming machine Since it is centrally integrated with the centralized management device at one point, it can be done very simply by disconnecting and connecting the control unit and the gaming machine.

Further, by rationalizing and consolidating the wiring process, the radio interference (occurrence of noise) picked up by the wiring can be reduced, and accurate data collection and smooth processing can be performed.

Particularly, according to the present invention, it is unavoidable that the fraud detection sensor as the fraud detection means disposed in the game machine is also destroyed by the exchange or discard of the game machine. Since the fraud detection processing means as a circuit for processing the signal can be left together with the control unit, it is not necessary to attach the fraud detection processing means as a circuit to each of the newly manufactured gaming machines. As a result, the procurement cost of the fraud detection processing means itself and the installation work cost for each game machine can be double reduced, and the cost reduction effect is extremely remarkable in the game machine industry in which the production amount reaches hundreds of thousands.

Further, the fraud detection processing means, which is conventionally arranged in the gaming machine and is itself susceptible to the adverse effect of noise, is set in the control unit appropriately separated from the gaming machine as described above. As a result, it is possible to separate from the gaming machine that is the target of the illegal game due to noise, and to avoid the adverse effect of picking up noise by the wiring itself that is lengthened by the redundant separation.
