Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a pachinko machine in which a discharge operation of a prize ball is stopped and controlled immediately when a ball breaks in the prize ball case.

[Conventional technology]

Conventionally, a switch for detecting out-of-balls is provided in the middle of the derivation trough that guides the free-representation balls in the free-representation ball tank to the free-reach gutter. A pachinko machine in which the ball discharging operation is stopped and controlled is known, for example, from Japanese Utility Model Publication No. 56-36542.

[Problems to be solved by the device]

In a conventional pachinko machine, if a ball stops due to dust mixing or ball pressure in the downstream part of the outlet gutter where a switch for detecting ball breakage is installed, the prize ball is supplied to the prize ball case. There is a problem that the prize ball discharging operation is performed in an empty state that is not performed.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to reliably detect a ball shortage in a prize ball case and more accurately perform a discharge operation of a prize ball. It is to provide a pachinko machine that can be performed.

[Means for solving the problem]

To achieve the above object, in a pachinko machine of the present invention, a fixed case portion having a plurality of ball passages for accommodating a certain number of prize balls, and an upper valve and a lower valve provided above and below the fixed case portion. And the upper valve and the lower valve are alternately opened and closed by the upward movement to discharge the prize ball in the fixed case part, and the prize ball case associated with the prize ball forcibly discharged by driving the motor. The prize ball discharge processing device for moving a moving body of the ball case upward and discharging a certain number of prize balls is provided, and a non-contact switch for detecting the prize balls is provided at an upper end of each ball passage of the prize ball case. , When all of the non-contact switches detect a premium ball, it outputs an output signal to keep the motor in a driving state, and when none of the non-contact switches detects a premium ball, it outputs an output signal. The driving of the motor is stopped thereby to disable the winning ball discharging operation and indirectly control the prize ball discharging operation.

[Action]

When the prize ball is normally stored in each ball passage of the prize ball case, each non-contact switch is turned on and outputs an output signal, and the output signal keeps the motor of the winning ball discharge processing device in a driven state. Then, the prize ball is surely discharged every time the winning ball is generated. On the other hand, when a ball break occurs in any of the ball passages of the prize ball case and the non-contact switch is turned off, the output signal is stopped and the prize ball discharge processing device motor is stopped to start the prize ball discharge operation. Stop doing it.

The prize sphere located at the upper end of ~ 60c is reflected, and the reflected light is detected by the light receiver to be turned on. The photoelectric switches 601a to 601c are connected to the motor 13 via the control circuit 18 as shown in the block diagram of FIG.
Connected to 1.

Next, the operation of this embodiment will be described with reference to FIG. That is, each ball passage 60a to 60c of the premium ball case 6
When there is a gift ball in all of, each photoelectric switch 601a-60
In 1c, the light emitted from the projector is reflected by the prize sphere, and the reflected light is incident on the receiver, thereby turning on.
Then, the control circuit 18 determines whether or not all the photoelectric switches 601a to 601c are turned on, and all photoelectric switches 60a to 601c are turned on.
If it is determined that 1a to 601c are ON, the motor 131
An output signal is transmitted to the motor 131, the motor 131 is kept in a driving state, and a prize ball is discharged every time a winning ball is generated.

On the other hand, when a ball break occurs in any of the discharge passages 60a to 60c of the premium ball case 6, the light emitted from the light projector does not enter the light receiver and is turned off. And the control circuit 18
When it is determined that any one of the photoelectric switches 601a to 601c is in the OFF state, the output signal to the motor 131 is stopped and the driving of the motor 131 is stopped to disable the winning ball discharging operation and indirectly. Disable the free ball discharge operation.

Although the photoelectric switches 601a to 601c have been described as direct reflection type in the above-described embodiments, for example, the transmission type may be a ON type when the prize ball blocks light. That is, as shown in FIG. 10, a photoelectric switch is provided for each of the passage holes 100a to 100c in the case 101 in which the passage holes 100a to 100c of the prize sphere that match the respective ball passages 60a to 60c of the prize ball case 6 are formed. The light emitters and the light receivers 601a to 601c may be provided so as to face each other, and the case 101 may be attached to the upper end of the fixed case portion 61 of the prize ball case 6. In this case, the photoelectric switches 601a to 601c are turned on when the light emitted from the light emitter to the light receiver is blocked by the prize ball.
As shown in the block diagram of FIG. 11, photoelectric switches 601a-60
When all the light of 1c is blocked, the output signal is sent to the motor 131, and when any one of the lights enters the light receiver, the output signal to the motor 131 is stopped.

Since it is assumed that the motor 131 is not driven even though one of the photoelectric switches 601a to 601c is out of order and the ball is not burned out, it is preferable to provide a circuit for disabling the photoelectric switches 601a to 601c.

The example in which light is applied as the non-contact switch has been described above, but a proximity switch or the like using high-frequency oscillation or magnetism can be considered as the non-contact switch.

[Effect of device]

As described above, according to the present invention, a non-contact switch for detecting a ball break is provided at the upper end of each ball passage of the prize ball case,
When any one of the ball passages runs out of ball, the motor of the winning ball discharging processing device is stopped to disable the winning ball discharging operation and indirectly stop the prize ball discharging operation. Therefore, it is possible to completely eliminate the inconvenience that the prize ball case is discharged while the prize ball case is empty as in the conventional pachinko machine.

Further, by using a non-contact switch as a switch for detecting a ball break, it can be effectively mounted on the prize ball case without taking up space.
