Description

[Detailed explanation of the invention] This invention has an accessory that operates when certain conditions are met, such as a ball entering a specific prize hole, and accepts the ball at a higher rate of entry than a normal prize hole. Regarding pachinko game machines.

In conventional pachinko game machines, the objects always operate for a certain period of time, and the number of balls that enter during the movement is unlimited, but recently, the number of balls that enter during the movement of the object is set to a predetermined number. Regulated by regulatory authorities to limit: Therefore, the number of balls entering the object is detected by a switching means such as a micro switch or a photoelectric switch, and the signal from the switching means is counted by a counter circuit, and when the number of balls entering the object reaches a predetermined number, Manufacturers of pachinko game machines are considering satisfying the regulations of regulatory authorities by immediately ending the action of the accessory even when the set time for the accessory object operation has not yet expired.

However, since pachinko game machines regulated in this way have inferior game performance, pachinko hall operators who purchase pachinko game machines deliberately cut the connection wire between the switching means and the counter circuit to enter the machine. There is a risk that the number of pitches cannot be counted, and that the accessory may be modified and used illegally so that it operates over a period of time regardless of the number of pitches entered. Regulatory authorities are also requesting manufacturers of pachinko game machines to be able to deal with the structure.

The present invention has been developed in view of the above circumstances, and its purpose is to provide a device equipped with a switching means and a counter circuit, in which when the connection line connecting the two is disconnected, an accessory operation invalidation signal is generated. To provide a pachinko game machine which is designed to continuously output and prevent the action of accessories from being performed at all, thereby preventing unauthorized modification.

An embodiment of the present invention will be described below with reference to the drawings. First, the board of a pachinko game machine is equipped with a normal winning hole and an accessory that operates and opens when a certain condition is met, such as when a ball enters a specific winning hole. The role of the accessory is well known in pachinko game machines, but for example, when it is activated, it accepts balls with an opening several times the width of the normal winning hole, and awards balls to the player depending on the number of balls that enter. The ball landing rate when this accessory is in operation is significantly higher than the ball landing rate in a normal winning hole when the accessory is not operating. Now, 1 is a normally closed type switching means for detecting the balls that have entered the above-mentioned object, such as a normally closed micro switch, which is used to line up the balls that have entered the object and pass them through the passage. It is on when a ball does not pass, and turns off for a short time when a ball passes. That is, the microswitch 1 is designed to generate a pulse signal with a shorter time width each time a ball enters the object. 2 is an input filter circuit consisting of three resistors 3, 4, 5 and a capacitor 6. The resistor 3 has a pull-down resistance value, and the resistor 4 and capacitor 5 form a time constant circuit for absorbing chattering. This input circuit 2 and micro switch 1 are
One end of the micro switch 1 is connected to the positive power supply terminal _VB via the connection line 7, and the other end of the micro switch 1 is connected to the input circuit 2 via the connection line 8. It is connected to the common connection point of the resistors 3 and 4. 9 is a waveform shaping circuit,

7, resistors 28 and 29, and a capacitor 30, one end of which is connected to the power supply terminal VB _.
It is connected to the. 31 and 32 are OR gates. Reference numeral 33 denotes an accessory action end signal generating device, which starts a timing operation when the accessory action starts, and when the predetermined period of time has elapsed, generates an accessory action end signal.
This _output terminal is connected to one input terminal of the OR gate 32.

The operation of the accessory is performed by, for example, an electromagnetic solenoid, and when certain conditions are met, the electromagnetic solenoid is energized to operate, and the output terminal of the OR gate 32 When the signal Oe becomes high level and the signal Oe is output, the power supply to the above-mentioned electromagnetic solenoid is cut off and the operation of the accessory is terminated.

Furthermore, in the above description, each component other than the microswitch 1 and the connection lines 7 and 8 is mounted on one printed circuit board.

Next, the operation of the above configuration will be explained. first,
When power is supplied, the input terminal of the inverter 27 is held at a low level while the capacitor 30 is charged via the resistor 28 of the initial reset signal generating circuit 26, so the output terminal of the inverter 27 is kept at a high level during this period. Initial reset signal
Or is output. This signal Or is the OR gate 31,
Since the signal Oe is given to the accessory through the OR gate 19, the accessory is always in a state of not operating when the power is turned on.
Since a high level signal is input to the clear terminal CL of the binary counter 17, the binary counter 17 is cleared. In this way, when a certain condition such as a ball entering a specific winning hole is met after power is supplied and the accessory starts operating, at the same time, the accessory operation end signal generating device 33 starts timing operation, Counter circuit 1
6 and when there is no output from the abnormality detection circuit 20, the high-level accessory operation end signal O1 output from the output terminal 33a of the accessory operation end signal generator 33 is output from the OR gate when the set _time has elapsed. 32, and the signal Oe is output from the output terminal of the OR gate 32, thereby terminating the operation of the accessory.

On the other hand, since the microswitch 1 is a normally closed type, normally a high level is given to one input terminal 11a of the NAND gate 11, its output terminal 11b is given a low level, and one input terminal 10a of the NAND gate 10 is given a high level. The output terminal 10b is stable at a high level. Therefore, when a ball enters the accessory while the accessory is operating as described above, the ball is aligned in the path and passes through the micro switch 1, and each time a ball passes through, the micro switch 1 is turned off for a short period of time, thus passing through the input filter circuit 2 to the NAND gate 11.
A low-level pulse signal with a short time width is input to the input terminal 11a of the device. This pulse signal is inverted by the waveform shaping circuit 9, its time width is made constant, and is input to the clock terminal CK of the binary counter 17 of the counter circuit 16.
will be counted. Then, when 10 balls pass through the micro switch 1, the output terminals _Q1 and _Q5 of the binary counter 17 become high level at the same time, so the AND gate 18 outputs a high level accessory operation end signal _O2 , OR gate 32
output changes to high level. Therefore, when the accessory operation signal O2 is output from the AND gate 18 before the accessory operation end signal _O1 is output from the output terminal 33a of the accessory operation end signal generator ₃₃ , the signal is immediately output from the OR gate 32. Oe is output and the operation of the accessory is completed, and at the same time, a high level signal is input to the clear terminal CL of the binary counter 17 via the OR gate 19, and the binary counter 17
is cleared. In this case, the number of balls that enter the accessory is
When the set time elapses with less than 10 objects, the action of the accessory is terminated by the accessory action end signal _O1 from the accessory action end signal generator 33, as described above.
At this time, the signal _O1 from the output terminal 33a is passed through the OR gate 19 to the clear terminal of the binary counter 17.
Since it is given to CL, the binary counter 17
The counts are cleared at the same time.

Next, the operation of the abnormality detection circuit 20 will be explained. Normally, when the microswitch 1 is on, the output of the waveform shaping circuit 9 is at a low level and the output of the inverter 21 is at a high level, so that the capacitor 25 is approximately fully charged. When the micro switch 1 is opened by the passing of the ball during the operation of the accessory, the waveform shaping circuit 9 is changed to a high level for a short time, and the output terminal of the inverter 21 is thereby changed to a low level. However, since the time constant of the integrating circuit consisting of the resistor 23 and the capacitor 25 is set to, for example, 10 times or more the time width of the output pulse of the waveform shaping circuit 9, the output terminal of the inverter 21 is connected to the microswitch as described above. Even if the input terminal of the inverter 22 changes to a low level for a short time due to turning off the inverter 22, the input terminal of the inverter 22 remains at a high level and does not change. Therefore, during normal operation, the abnormality detection circuit 20 does not generate an output and the The output terminal remains at low level.

By the way, when a pachinko hall operator or the like disconnects one or both of the connection lines 7 and 8 in an attempt to improve the gameplay, the on/off status of the micro switch 1 is not transmitted to the counter circuit 16, and therefore, no damage is caused to the accessories. It becomes impossible to detect the number of balls entering. However, in such a case, the waveform shaping circuit 9
Since the input terminal 11a of the NAND gate 11 is grounded by the resistor 3 with a small resistance value, it is maintained at a low level, and the output terminal 11b of the NAND gate 11 changes to a high level, and one of the NAND gates 10 input terminal 10a of
is stable at a low level and the output terminal 10b is at a high level. Since the output terminal 11b of the NAND gate 11 is maintained at a high level in this way, the output of the inverter 21 is maintained at a low level, which is determined by the time constant of the integrating circuit consisting of the resistor 23 and the capacitor 25. As time passes, the input terminal of the inverter 22 changes to low level, and its output terminal becomes high level.
This high level signal is given to the OR gate 32 via the OR gate 31 as the accessory operation invalidation signal _O3 , and the signal Oe is continuously output from the OR gate 32. As a result, the connection line 7, After one or both of 8 is disconnected and some time has passed, the signal Oe is continuously output.
The character's actions will not be performed at all.

Since the abnormality detection circuit 20 operates as explained above, by cutting one or both of the connecting lines 7 and 8, the number of entering balls detected by the micro switch 1 can be prevented from being applied to the counter circuit 16. Even if an unauthorized modification is made in an attempt to improve the gameplay by making the action of the accessory last for a certain amount of time regardless of the number of balls that enter the game, the action of the accessory will no longer be performed at all in the modified state. Therefore, the purpose of the modification cannot be achieved, and therefore, the presence of the above-mentioned abnormality detection circuit 20 reliably prevents unauthorized modification.

In addition to the micro switch 1, a photoelectric switch or a magnetic switch may be used as the switching means, and the accessory operation end signal generating device outputs an operation end signal at a set time as described above. Alternatively, the operation end signal may be output under other conditions.

In addition, the present invention can be implemented with various modifications without changing the gist, and the configuration of each circuit may be replaced with a microcomputer to perform the same function.

As is clear from the above description, the present invention is equipped with a switching means and a counter circuit in order to regulate the number of balls entering during the operation of the accessory, and is useful when the connecting wire connecting the two is cut. It is possible to provide a pachinko game machine in which the object motion invalidation signal is continuously output, so that the accessory object does not move at all, thereby preventing unauthorized improvements.
