Description

  The present invention relates to a ball game machine typified by a pachinko machine, and more particularly to a game ball passage detection device that detects the passage of a game ball with a prize-winning tool or the like provided on the front surface of a game board.

  Pachinko machines are used to launch and supply game balls into the game area defined on the front side of the game board by using a launching device to drop and move in the game area, and a prize formed in the game area in the middle of the fall movement. A game ball is won in the mouth, and the game is used to acquire a prize ball in accordance with this. For example, when a game ball fired in the game area enters a winning opening (a general winning opening, a big winning opening, etc.), control for detecting the winning and operating the winning ball payout device is performed. A predetermined number of prize balls are paid out.

  For this reason, the pachinko machine is provided with a game ball passage detection device having a ball detector that detects the winning of a game ball and a determination device that receives a detection signal from the detector and determines whether there is a winning or not. The operation control of the prize ball payout device is performed based on the determination result of the determination device.

  An example of a conventional game ball passage detection device is shown in FIG. 9, and this device includes a ball detector 110 provided at a winning opening of a winning tool. The ball detector 110 is connected to a power source 100 (for example, having a voltage of + 12V) via a power supply line 101, and a first signal line 102 extends from an output terminal 110b of the ball detector 110, so that a game ball that has entered the winning opening passes therethrough. It has a ball passage hole 110a. The ball detector 110 always outputs a high potential signal from the power supply 100 to the first signal line 102 from the output terminal 110b, and the voltage from the power supply when the game ball entering the winning opening passes through the ball passage hole 110a. And a low potential signal is output from the output terminal 110 b to the first signal line 102.

  The first signal line 102 is connected to the relay board 120 via the first connector 103, and is connected to the second signal line 104 via the second connector 105 from the internal signal line 121 in the relay board 120. The second signal line 104 is connected to the determination device 131 in the main control board 103 via the third connector 106. The internal signal line 121 is connected to a ground line 123 having a first resistor 122 (for example, a resistance value of 750Ω) and connected to the ground, and further includes a stabilization circuit 125 including a resistor 126 and a capacitor 127. .

  In the gaming ball detection device configured as described above, a high potential signal is output from the output terminal 110b in a state where the ball does not pass through the ball passage hole 110a of the ball detector 110, that is, always. This high potential signal is transmitted to the determination unit 131 via the first and second signal lines 102 and 104 and the internal signal line 121 although there is a slight voltage drop due to the first resistor 122 via the ground line 123. Is done. While receiving the high potential signal, the determiner 131 determines that the sphere has not passed the sphere passing light 110a of the sphere detector 110. On the other hand, when the sphere passes through the sphere passage hole 110a of the sphere detector 110, a low potential signal is output from the output terminal 110b, which is sent to the determiner 131, and the determiner 131 determines that the sphere has passed. In addition, as this sphere detector 110, there exists a thing disclosed by patent document 1, for example.

JP 2005-147331 A

  In the gaming ball detection device configured as described above, the first or second connector 103, 105 is disconnected, and so on, so that the output terminal 110b of the ball detector 110 and the input terminal of the main control board 130, that is, the third connector 106 are connected. When the signal line between them is broken, only the low potential signal is input to the determiner 131, and the determiner 131 mistakenly detects the passage of the sphere even though the sphere detector 110 has not detected the passage of the sphere. A problem such as determining and performing winning control occurs. In particular, in a pachinko machine, the relay board is arranged on the back side of the gaming machine, and the first or second connector 103, 105 is illegally accessed from the outside, and is attached or detached. It has been found that there is a problem that even though there is no winning of a ball, the determination unit 131 makes a winning determination and illegally pays out a winning ball.

  In view of such a problem, the present invention provides a game ball passage detection device in which even when a disconnection or the like occurs between a ball detector and a determiner, the determiner may not erroneously detect a ball passage. For the purpose.

A ball detector that outputs a low potential signal by lowering the voltage from the power source and a potential signal output from the ball detector to determine whether or not the game ball of the passing member has passed. A determination device is connected to the potential signal output terminal portion of the sphere detector and the potential signal input terminal portion of the determination device, and the potential signal output from the sphere detector is transmitted to the determination device. A signal line and a first resistor with a predetermined electrical resistance. A ground line that connects the signal line to the ground via a resistor, and a power supply line that connects the power source and the signal line via a second resistor having a resistance value sufficiently larger than the first resistor. Configured. In addition, the power supply line is connected to the signal line at a position in the signal line close to the determiner, and the ground line is connected to the signal line at a position in the signal line close to the sphere detector. Has been.

  In this game ball passage detecting device, the signal line is connected to the connector at the intermediate portion, the power supply line is connected to the signal line on the determination side from the connector connecting portion, and the ground line is It is preferable to be connected to the signal line on the sphere detector side from the connector connecting portion.

  Further, a relay board is provided in the middle of the signal line, and the signal line includes a first signal line that connects the ball detector and the relay board, and a second signal line that connects the relay board and the determination unit. The power supply line may be connected to the second signal line, and the ground line may be connected to the first signal line.

  According to the second aspect of the present invention, a game ball is used in a ball game machine that launches a game ball into a game area formed on the front surface of the game board and places the game ball into a winning device in the game area. A game ball passage detecting device that detects the passage of the game ball is disposed in a passage member that allows the game ball to pass therethrough, and the output terminal portion is always grounded to output a low potential signal, and the game ball passes through the passage member. A ball detector that outputs a high potential signal from a power source connected to the output terminal unit when passing, and a potential signal output from the ball detector is received to determine whether or not the game ball of the passing member has passed. The potential signal output terminal of the sphere detector and the potential signal input terminal of the determiner are connected to transmit the potential signal output from the sphere detector to the determiner. Signal line and a predetermined electrical resistance value Configured with a ground line for grounding connected to the signal line via a first resistor, and a power supply line connecting the power source and the signal line. In addition, the power supply line is connected to the signal line at a position in the signal line close to the ball detector, and the ground line is connected to the signal line at a position in the signal line close to the determiner.

  According to the ball and ball game machine according to the first aspect of the present invention configured as described above, the power supply line is connected to the signal line at a position close to the determiner, and the ground line is at a position close to the ball detector. Since it is connected to the signal line, if a break occurs in the middle of the signal line, the signal line connected to the determiner is disconnected from the ground line and connected to the power supply line. The state in which the potential signal is transmitted is maintained, and the ball passage is not erroneously detected by the determiner. In a normal state where there is no disconnection, when the ball detector detects the passage of the ball and outputs a low potential signal, the resistance value of the second resistor arranged in the power supply line is the first value arranged in the ground line. Since it is sufficiently larger than the resistance value of one resistor, the potential of the signal line is held at a low potential, and the low potential signal is input to the determination device to accurately detect the passage of the sphere.

Such fraud can be prevented by connecting a ground line to the first signal line to be connected and connecting a power supply line to the second signal line to connect the relay board and the determination device.

  Further, according to the bullet ball game machine according to the second aspect of the present invention, the power supply line is connected to the signal line at a position close to the ball detector, and the ground line is connected to the signal line at a position close to the determiner. Therefore, when a disconnection occurs in the middle of the signal line, the signal line connected to the determination device is connected to the ground line and disconnected from the power supply line, and the determination device has a low potential signal. Is maintained, and the passage of the sphere is not erroneously detected by the determiner.

  It should be noted that the operation for illegally disconnecting a signal line in a gaming machine is typically performed by illegally attaching or detaching the connector of the signal line, so that the signal line is connected to the connector at the intermediate portion. If this is the case, connect the power supply line to the signal line on the sphere detector side from the connector connection, and connect the ground line to the signal line on the determiner side from the connector connection. it can.

  Similarly, when a relay board is provided in the middle of the signal line, it is typical that an unauthorized operation is performed on a connection portion of the relay board, that is, a connection connector. Such fraud can be prevented by connecting a power line to the first signal line to be connected and connecting a ground line to the second signal line to connect the relay board and the determination device.

This corresponds to the game ball passage detection device of the present invention, and this configuration will be described below.

First Embodiment FIG. 5 shows an electric circuit configuration of a game ball passage detecting device as a first embodiment. Since this apparatus is similar in configuration to the conventional apparatus shown in FIG. 9, the same functional parts will be described with the same numbers.

  This game ball passage detection device includes a ball detector 110 provided at a winning opening of a winning tool. The ball detector 110 is connected to the power source 100 (for example, having a voltage of + 12V) via the first power supply line 101, and the output terminal 110b is connected to the first signal line 102. Has a ball passage hole 110a through which the water passes. The sphere detector 110 is configured by a known high-frequency oscillation type proximity switch, and is configured by connecting a detection circuit to a coil provided in an outer peripheral portion of the through hole. The impedance of the coil changes when a steel game ball approaches or moves away from the ball passage hole 110a. This is detected by a detection circuit. When there is no ball passage detection, a high potential signal from the power supply 100 is output to the output terminal 110b. From the output terminal 110b to the first signal line 102 and output a low potential signal from the output terminal 110b. To do.

  The first signal line 102 is connected to the switch / solenoid relay board 120 (hereinafter simply referred to as the relay board 120) via the first connector 103, and is connected to the first internal signal line 121 in the relay board 120. The second signal line 104 is connected via the second connector 105. The second signal line 104 is connected to the determination device 131 in the main control board 103 via the third connector 106 and the second internal signal line 132. In the relay substrate 120, a stabilization circuit 125 including a resistor 126 and a capacitor 127 is provided.

  The first signal line 102 is connected to a ground line 116 having a first resistor 115 (for example, a resistance value of 750Ω) and connected to the ground. In the main control board 103, a power source 135 (for example, a voltage of + 12V) is provided via a second power supply line 137 in which a second resistor 136 having a very large resistance value (for example, 1 MΩ) is disposed. Power source) and the second internal signal line 132 are connected. The second power supply line 137 corresponds to the power supply line of claim 1.

  In the gaming ball detection device configured as described above, a high potential signal is output from the output terminal 110b when the ball does not pass through the ball passage hole 110a of the ball detector 110. Although this high potential signal has a slight voltage drop through the ground line 116 due to the first resistor 115, the first signal line 102, the first internal signal line 121, the second signal line 104, and the second internal signal. The data is transmitted to the determiner 131 via the line 132. While receiving the high potential signal, the determiner 131 determines that the sphere has not passed the sphere passing light 110a of the sphere detector 110. At this time, power is supplied from the power source 135 via the second power supply line 137, but the input signal to the determination unit 131 is a high potential signal and has no effect.

  On the other hand, when the sphere passes through the sphere passage hole 110a of the sphere detector 110, a low potential signal is output from the output terminal 110b, and the first signal line 102, the first internal signal line 121, the second signal line 104, and the second signal line. The internal signal line 132 is in a low potential state. Even in this state, power is supplied from the power source 135 through the second power supply line 137, but the resistance value of the second resistor 136 provided in the second power supply line 137 is provided in the ground line 116. The potential of the signal lines 102, 121, 104, and 132 is maintained at a low potential because it is sufficiently larger than the resistance value of the first resistor 115 (for example, 1000 times larger). For this reason, a low potential signal is sent to the determiner 131, and the determiner 131 determines that the ball has passed, that is, the game ball has won a prize.

  FIG. 6 shows the change in the input potential signal level to the determiner 131 at this time, and when the sphere is not passing through the sphere passage hole 110a of the sphere detector 110 (between t1 and t2 and between t3 and t4). The input potential signal becomes a high potential signal α11 having a voltage V1 slightly lower than the power supply voltage V0 (= + 12V). When the sphere passes through the sphere passage hole 110a (between t2 and t3), the input potential signal The signal becomes a low potential signal α12 having a voltage level V2 slightly higher than the ground voltage (= 0V).

  Next, a case where the signal line from the output terminal 110b of the ball detector 110 to the main control board 130 (the third connector 106 thereof) is disconnected due to the disconnection of the first connector 103 and the second connector 105 will be described. When such a disconnection occurs, electricity cannot flow to the signal line side, so voltage is supplied from the power supply 135 via the second power supply line 137, and the voltage of the power supply 135 is almost supplied to the determiner 131. Therefore, the determiner 131 determines that there is no sphere passing. The change in the input potential signal level to the determiner 131 at this time is shown in FIG. 6, and a disconnection occurs between times t4 and t5, and the determiner 131 has almost the same voltage as the power supply voltage V0 (= + 12V). The signal is input.

  As can be seen from the above description, the determination circuit 131 does not determine that the ball has passed even if an unauthorized operation such as removing a connector in the middle of the signal line is performed, and the illegally paying out a prize ball is performed by such an unauthorized operation. Can be prevented. As can be understood by comparing the circuit configuration according to the present invention shown in FIG. 5 with the conventional circuit configuration shown in FIG. 9, in the present invention, a second power supply line 137 is added and a second power supply is added. The game ball passage detecting device of the present invention can be configured with an inexpensive and simple configuration by only limiting the connection points of the supply line 137 and the ground line 116, and unauthorized operation can be reliably prevented.

  As can be seen from the above configuration and operation, the second power supply line 137 only needs to be connected to the determination unit 131 from the location where the disconnection occurs, and the ground line 116 detects the sphere from the location where the disconnection occurs. What is necessary is just to be connected to the side of the vessel 110. For example, in order to prevent unauthorized operation due to unauthorized attachment / detachment of the first and second connectors 103 and 105, the second power supply line 137 is connected to the second signal line 104 or the second internal signal line 132, and the ground line 116 is connected. What is necessary is just to connect to the 1st signal line 102.

Second Embodiment FIG. 7 shows an electric circuit configuration of a game ball passage detecting device as a second embodiment. Also in this apparatus, the same functional parts as those in the first embodiment and the conventional apparatus shown in FIG.

  This game ball passage detection device includes a ball detector 150 provided at a winning opening of a winning tool. The ball detector 150 has a ball passage hole 150a through which a game ball that has entered the winning opening passes, and is connected to the ground via the earth line 111, and the output terminal 150b is connected to the first signal line 102. The sphere detector 150 is also composed of a known high-frequency oscillation type proximity switch, and when there is no sphere passing detection, the output terminal 150b is connected to the earth line 111 side, and a low potential signal is connected from the output terminal 150b to the first signal line 102. Output to.

  On the other hand, when the game ball entering the winning opening passes through the ball passage hole 150a, the internal signal line connected to the output terminal 150b is electrically disconnected. Here, the first signal line 102 is connected to a power supply line 142 connected to a power supply 140 via a resistor 141. Normally, the potential of the first signal line 102 is supplied with a voltage from the power supply 140 via the power supply line 142. In response to the high potential, that is, a high potential signal is output from the output terminal 150 b to the first signal line 102.

  The first signal line 102 is connected to the relay board 120 through the first connector 103, and is connected from the first internal signal line 121 in the relay board 120 to the second signal line 104 through the second connector 105. The second signal line 104 is connected to the determination device 131 in the main control board 103 via the third connector 106 and the second internal signal line 132. In the relay substrate 120, a stabilization circuit 125 including a resistor 126 and a capacitor 127 is provided. Furthermore, the second signal line 104 is connected to a ground line 118 having a resistor 117 and connected to the ground.

  In the gaming ball detection device configured as described above, when the ball does not pass through the ball passage hole 150a of the ball detector 150, a low potential signal is output from the output terminal 150b to the first signal line 102 as described above. Is done. The low potential signal is transmitted to the determination unit 131 via the first signal line 102, the first internal signal line 121, the second signal line 104, and the second internal signal line 132. While receiving the low potential signal, the determiner 131 determines that the sphere has not passed the sphere passing light 150a of the sphere detector 150.

  On the other hand, when the sphere passes through the sphere passage hole 150 a of the sphere detector 150, the internal signal line connected to the output terminal 150 b is electrically disconnected, and the potential of the first signal line 102 is supplied from the power supply 140 via the power supply line 142. Therefore, a high potential signal is output from the output terminal 150b. This high potential signal is transmitted to the determination unit 131 via the first and second signal lines 102 and 104 and the internal signal lines 121 and 132, although there is a voltage drop via the ground line 118 due to the resistor 117. . When receiving the high potential signal, the determiner 131 determines that the sphere has passed the sphere passing light 150a of the sphere detector 150. Note that the resistance value of the resistor 141 of the power supply line 142 is set smaller than the resistance value of the resistor 117 of the ground line 118 in order to suppress a voltage drop due to the ground line 118.

  FIG. 8 shows the change in the input potential signal level to the determiner 131 at this time, and when the sphere does not pass through the sphere passage hole 150a of the sphere detector 150 (between t11 and t12 and between t13 and t14). The input potential signal becomes a low potential signal α21 having a voltage V2 slightly higher than the ground voltage (= 0V). When the sphere passes through the sphere passage hole 150a (between t12 and t13), the input potential signal Becomes a high potential signal α22 having a voltage V1 slightly lower than the power supply voltage (= + 12V).

  Next, a case where the signal line from the output terminal 150b of the ball detector 110 to the main control board 130 (the third connector 106 thereof) is disconnected due to the disconnection of the first connector 103 and the second connector 105 will be described. When such a disconnection occurs, the current flowing from the power supply line 142 to the first signal line 102 cannot flow to the determiner 131, and the determiner 131 is connected to the second internal signal line 132 and the second signal line 104. Since the ground potential is connected via the ground line 118 and a low potential signal is input to the determiner 131, the determiner 131 determines that there is no ball passing. The change in the input potential signal level to the determination unit 131 at this time is shown in FIG. 8, and a disconnection occurs at time t14 to t15. input.

  As can be seen from the above description, even in the case of the second embodiment, even if an unauthorized operation such as removing a connector in the middle of the signal line is performed, the determination circuit 131 does not determine that the ball has passed. It is possible to prevent the prize ball from being illegally discharged by the operation.

  As can be seen from the above configuration and operation, the power supply line 142 only needs to be connected to the sphere detector 150 side from the location where the disconnection occurs, and the ground line 118 is determined from the location where the disconnection occurs. It only needs to be connected to the other side. For example, in order to prevent unauthorized operation due to unauthorized attachment / detachment of the first and second connectors 103 and 105, the power supply line 142 is connected to the first signal line 102 and the ground line 118 is connected to the second signal line 104. good. Note that the resistor 141 of the power supply line 142 may be built in the sphere detector 150.
