Abstract

PROBLEM TO BE SOLVED: To enable the reliable detection of the passage of pin balls without being affected by radio waves. SOLUTION: A mechanical switch 7 and a proximity switch 9 are sequentially arranged along a ball passage hole and are sequentially turned on every time a ball passes. A one-shot circuit 17 outputs a one-shot signal only for a predetermined period of time from the ON timing of the mechanical switch 7. A gate circuit 18 in the state of receiving the input of the one shot signal and of receiving the input of the ON signal from the proximity switch 9 outputs a ball prize- winning signal. In this case, though the proximity switch 9 can be turned on owing to a malfunction under the influence of radio waves, as the mechanical switch 7 is not affected by radio waves, it is possible to detect balls passing through the passage hole with reliability.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball detecting device of a pachinko game machine for detecting the passage of a pachinko ball having won a winning hole.

[0002]

In recent years, in a pachinko hall, the passage of a pachinko ball that has won a prize hole in a pachinko game machine is detected by transmitting a powerful radio wave from an illegally modified portable transmitter. In order to obtain pachinko balls by erroneously operating a proximity switch, there is a fraud. That is, since the proximity switch is turned on due to malfunction due to the influence of the radio wave, the control device determines that the pachinko ball has won the winning hole and erroneously releases the prize ball.

[0003] In this case, by detecting the passage of a pachinko ball using a mechanical switch (micro switch), it is possible to prevent the influence of unauthorized radio waves,
When the pachinko balls pass continuously due to low response, there is a disadvantage that the mechanical switch cannot return from the on state to the off state and the pachinko balls cannot be detected.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a ball detection device of a pachinko game machine capable of reliably detecting the passage of a pachinko ball without being affected by radio waves. It is in.

[0005]

According to the present invention, there is provided a ball detecting device for a pachinko game machine which detects a pachinko ball passing through a prize-winning path of a pachinko game machine, and is turned on as the pachinko ball passes the prize-winning path. A mechanical switch is provided, and a proximity switch that is turned on in response to the pachinko ball passing through the winning path is provided, and it is detected that the pachinko ball has passed the winning path based on the ON state of the mechanical switch and the proximity switch. (See Claim 1).

According to such a configuration, when the pachinko ball that has won the winning hole passes through the winning path, the mechanical switch and the proximity switch are turned on. Then, the detecting means detects that the pachinko ball has passed the winning path based on the ON state of the mechanical switch and the proximity switch.

[0007] Even if the proximity switch malfunctions due to an illegal radio wave and is turned on while pachinko balls do not pass through the winning path, the mechanical switch is turned off without being affected by the illegal radio wave. Therefore, the detecting means can determine that the pachinko ball has not passed the winning path.

Further, even when a mechanical switch having low responsiveness does not return from the on state to the off state due to the continuous passage of the pachinko ball through the winning path, the proximity switch having high responsiveness responds to the passage of the pachinko ball. The detection means can detect pachinko balls passing continuously.

In the above configuration, the mechanical switch and the proximity switch are sequentially arranged along a winning path, and the detecting means detects that the proximity switch is turned on by a predetermined time after the mechanical switch is turned on. When turned on, it may be determined that a pachinko ball has passed through the winning path (claim 2).

[0010] According to such a configuration, even if the proximity switch is turned on after the mechanical switch is turned on in response to the pachinko ball passing the winning path, the detecting means is provided with:
The passage of the pachinko ball can be reliably detected.

[0011] Further, the mechanical switch and the proximity switch are arranged at the same detection point on a winning path,
The proximity switch may be set to an on state when the mechanical switch is on (claim 3).

According to such a configuration, the mechanical switch and the proximity switch are turned on substantially simultaneously according to the pachinko balls passing through the winning path. At this time, even if the mechanical switch chatters, the proximity switch is set to be in the on state when the mechanical switch is on, so that the detecting means can perform pachinko without being affected by chattering. The passage of the ball can be reliably detected.

BEST MODE FOR CARRYING OUT THE INVENTION

(First Embodiment) A first embodiment of the present invention will be described below with reference to FIGS. 2 shows a plan view of the ball detecting device, and FIG. 3 shows a cross section of the ball detecting device. 2 and 3, the ball detection device 1 is disposed in correspondence with a winning hole of a pachinko game machine (not shown), and detects a pachinko ball that wins a winning hole and passes through a winning path. Things.

A ball passing hole 3 (corresponding to a winning path) is formed in the main body 2 of the ball detecting device 1, and a pachinko ball passing through the winning path passes through the ball passing hole 3. A component room 5 is formed in the main body 2 so as to be separated by the ball passage hole 3 and the partition wall 4, and the printed circuit board 6 is housed in the component room 5.

A mechanical switch 7 (micro switch) is mounted on the surface of the printed circuit board 6, and an operator 7a of the mechanical switch 7 projects into the ball passage hole 3 while penetrating the partition wall 4. I have. In this case, a tongue piece 8 is rotatably supported on the partition wall 4, and the tongue piece 8 is pressed by a pachinko ball and presses the operation element 7a, whereby the mechanical switch 7 is turned on. (See FIG. 4). The lead terminal 7b of the mechanical switch 7 is connected to the printed circuit board 6.

On the back surface of the printed circuit board 6, a coil 10 and a detection circuit 11 constituting the proximity switch 9 are mounted. In this case, the detection circuit 11
Are included.

FIG. 5 schematically shows the electrical configuration of the proximity switch 9. In FIG. 5, the coil 10 is connected to the oscillation circuit 12, and generates a high-frequency magnetic field from the coil 10 in a state where a high-frequency signal is given from the oscillation circuit 12. The amplifier 13 amplifies and outputs a high-frequency signal supplied to the coil 10.

The comparator 14 compares the signal level of the signal from the amplifier 13 with the reference voltage output from the reference voltage generating circuit 15, and outputs a detection signal when the signal level is lower than the reference voltage.

FIG. 1 schematically shows the configuration of the detection circuit 11. In FIG. 1, a detection circuit 11 inputs detection signals from a mechanical switch 7 and a proximity switch 9 via an input circuit 16. One-shot circuit 17 outputs a one-shot signal for a predetermined time from the input timing of the ON signal from mechanical switch 7. The one-shot circuit 17 has a retriggerable function. When the mechanical switch 7 is turned on again in the output state of the one-shot signal, the one-shot circuit 17 outputs the one-shot signal again for a predetermined time from that timing. The gate circuit 18 outputs a ball winning signal while the one-shot signal from the one-shot circuit 17 and the detection signal from the input circuit 16 are simultaneously input.

Next, the operation of the above configuration will be described. When the pachinko ball hit on the board of the pachinko game machine wins the winning hole, the pachinko ball passing through the winning path passes through the ball passing hole 3 of the ball detecting device 1. Then, since the tongue piece 8 is pressed by the pachinko ball passing through the ball passage hole 3, the operator 7a of the mechanical switch 7 is pressed, and the mechanical switch 7 is turned on accordingly.

The one-shot circuit 17 of the detection circuit 11
When the mechanical switch 7 is turned on, a one-shot signal is output for a predetermined time from the timing (see FIG. 6).
Then, when the pachinko ball further passes through the ball passage hole 3,
When the mechanical switch 7 is turned on, the proximity switch 9 is turned on.
Turns on.

At this time, since the one-shot signal is output from the one-shot circuit 17 in response to the turning on of the mechanical switch 7, the gate circuit 18 responds to the output of the on signal from the proximity switch 9 by the ball. The winning signal is output to a control device (not shown) of the pachinko game machine. Accordingly, the control device determines that the pachinko ball has won the winning hole and releases a predetermined number of prize balls.

The proximity switch 9 is mainly composed of the coil 10 and is susceptible to electrical noise as compared with the mechanical switch. Is transmitted, the proximity switch 9 may be turned on under the influence of the radio wave and the prize ball may be erroneously paid out even though the pachinko ball has not won the prize hole.

However, when the ON signal is input from the proximity switch 9, the gate circuit 18 of the detection circuit 11 sends the ball winning signal to the control device on condition that the one-shot signal is input from the one-shot circuit 17. Since the signal is output, the ball winning signal is not output only by turning on the proximity switch 9 under the influence of the radio wave.

When a pachinko ball continuously passes through the ball passing hole 3 of the ball detecting device 1 by successively winning a pachinko ball in the winning hole, the output of the one-shot signal from the one-shot circuit 17 is performed. Although the state continues, the responsiveness of the proximity switch 9 is high and the proximity switch 9 is turned on / off in response to the passage of the pachinko ball.
, A ball winning signal is output, and the control device can surely pay out a prize ball according to the ball winning signal.

According to the above configuration, the mechanical switch 7 and the proximity switch 9 are used as the ball detecting device 1 for detecting pachinko balls passing through the winning path of the pachinko game machine.
And a ball winning signal is output from the detection circuit 11 based on the ON state of each of the switches 7 and 9, so that the proximity switch 9 is erroneously turned on due to the influence of radio waves. Also, it is possible to prevent the ball winning signal from being output from the detection circuit 11. Therefore, compared to a configuration in which a ball winning signal is output to the control device in response to the turning on of the proximity switch, the prize ball can be reliably paid out from the pachinko game machine without being affected by the radio wave.

(Second Embodiment) FIGS. 7 to 9 show a second embodiment of the present invention.
Fig. 3 shows a ball detecting device according to an embodiment, in which the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted; only different components will be described. The second embodiment is characterized in that the mechanical switch 7 and the proximity switch 9 are set at the same detection point.

That is, the mechanical switch 7 and the magnetic switch 9
Are set at the same detection point with respect to the ball passage hole 3, and both switches are set to be turned on substantially simultaneously as the pachinko ball passes through the ball passage hole 3.

In this case, as shown in FIG. 9, the magnetic switch 9 is set to the on state when the mechanical switch 7 is on. The detection circuit 11 outputs a ball winning signal when both the mechanical switch 7 and the proximity switch 9 are turned on.

According to the second embodiment, the one-shot circuit for outputting the one-shot signal in response to the ON signal from the mechanical switch 7 can be omitted, and the mechanical switch 7 can chatter. Therefore, a waveform shaping circuit for preventing the influence of the circuit can be omitted, and the overall circuit configuration can be extremely simplified.
That is, the detection circuit 11 may be an AND circuit. Since the mechanical switch 7 and the proximity switch 9 are located at the same detection point, the ball detection device 1
Can be set small.

(Third Embodiment) The arrangement of the mechanical switch 7 and the proximity switch 9 is set so as to be perpendicular to the center of the ball passage hole as shown in FIGS. According to such an arrangement, it is possible to reduce the thickness of the ball detecting device and also set the protruding area to the board surface small.

The present invention is not limited to the above embodiment, but can be modified or expanded as follows. A waveform shaping circuit for shaping the ON signal from the mechanical switch 7 may be provided so that the ON timings of the mechanical switch 7 and the proximity switch 9 are completely matched.
The magnetic switch 9 and the mechanical switch 7 may be arranged in order along the ball passage hole 3.

[0033]

As is apparent from the above description, according to the ball detecting device of the pachinko game machine of the present invention, a mechanical switch and a proximity switch are combined, and a winning path is determined based on the ON state of both switches. The pachinko ball that passes through is detected, so it is possible to reliably detect the passage of the pachinko ball without being affected by radio waves, and it is possible to reliably pay out prize balls from pachinko game machines. It works.
