Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko machine.
For more information on the ball game machines that are used,
Game balls stored in the tank member provided in the
Ball game machine having a detection switch for detecting whether or not there is
Prize ball mechanism. 2. Description of the Related Art A pachinko machine exemplified as a typical example of a ball and ball game machine is disclosed.
In the dick machine, the upper and lower ball dishes and the ball launcher etc. are attached
Behind the front frame, the prize ball payout device and the processing path of the game ball
The back set board provided with a
Is always closed while covering the back of the front frame.
Skilled. A container with an open top at the top of the back set panel
A prize ball mechanism provided with a tank member formed in
And the supply duct on the side of the game facility located above the tank member.
To receive and replenish game balls from
In addition, the stored game balls are supplied to the prize ball payout device to pay prize balls.
It is configured to protrude. Here, payout of game balls by the prize ball payout device
Is performed according to a predetermined winning state on the game board.
Therefore, the number of game balls stored in tank members is constantly decreasing.
Not fixed. For this reason, in pachinko machines, storage is
Prize ball cut to detect if the number of game balls to stay is over a predetermined amount
Detection device is provided.
Information is passed through the pachinko machine terminal platform to the gaming facility
Game ball supply device, and the number of stored balls is less than the predetermined amount.
It is configured to prompt the replenishment of the game ball when it is hit.
As a prize ball out detecting device with such a function, tank
A swingable lever member located on the bottom of the member
From the detection switch that detects the tilt angle position of the bar member
The storage ball located above the lever member is gone
When the pressing force is released and the lever member tilts, the detection
The switch is configured to detect its tilt angle position.
Have been. The detection switch is related to the supply path of the game ball.
And so on, generally on the front side of the back set board (game board side).
It is attached. Here, from the detection switch and this switch,
Circuit board receiving terminal detection signal (eg terminal board)
Is connected by a signal line.
It needs to be routed at the top of the board. In recent years,
Arc for releasing the charge of the game balls stored in the
Metal fittings are provided near the tank member,
Ground wires etc. to be connected to the metal fittings are also placed at the top of the back set panel
There is a need. For this reason, in the conventional pachinko machine,
Horizontally below the detection switch on the front side of the back set panel
Forming a rib-shaped support bar extending to
Place cables such as signal wires and ground wires on the
This prevented the cable from sagging. [0005] However, the above-mentioned problems
In such a conventional configuration, the cable rests on the top of the support bar.
The back set panel is opened and closed because it is only placed
As the cable fell off the support bar,
When the back set panel is closed behind the front frame,
Damage by pinching between the front end face of the holding section and the game board
There was a problem that there was a possibility. Also a detection switch
With the conventional mounting method that fixes the screws directly,
Overtightening may damage the detection switch itself.
There was another problem. On the other hand, in order to solve the problem of cable damage,
A separate wiring cover that covers the front side of the support bar
To fix the screws, or attach a cylindrical wiring
For example, a method of integrally forming the members is devised. But the former
Increases the number of parts and assembly work,
The configuration of the set panel becomes complicated and the wiring work becomes complicated.
All have technical issues to be resolved.
You. The present invention addresses these problems and technical problems.
It was made in view of the above, and increases the number of work steps
Solves the problem of cable damage with a simple and easy configuration
Prize for a ball game machine that can prevent damage to the detection switch
It is intended to provide a ball mechanism. [0008] To achieve the above object, the present invention
The invention relates to a frame member and a back side of the frame member which can be opened and closed freely.
Attach to the back set board and the top of the back set board
It is formed into a container with an open top and stores game balls.
From the outlet opening provided in the downstream part of the bottom.
Tank member for supplying the game ball and the outlet of the tank member
Supplied at the bottom of the opening and supplied from the outlet opening
A ball passage member for guiding a game ball to a prize ball dispensing device, and a tank member
It is located on the bottom of and is pivoted up and down freely.
A lever member, and a lever disposed below the lever member.
Detect the tilt angle position of the bar member and store it in the tank member
A detection switch that detects the out-of-ball condition of
Secure the detection switch to the back set panel below the lever member.
And a switch cover member to be held.
Connect the cable passing near the detection switch to the back
Between the ball and ball game machine
Construct the prize ball mechanism. [0009] In the prize ball mechanism having the above structure, the storage in the tank member is performed.
The state of running out of game balls (the number of stored game balls
Detection switch that detects whether the switch is
It is fixed and held on the back set board using bar members
In addition, this switch cover member has the vicinity of the detection switch
Holds and holds the passing cables between
A holding part is formed. Therefore, the above-mentioned ground wire etc.
Cable is held by the holding piece,
These cables hang even after repeated opening and closing
Cable when closing the back set panel.
There is no such thing as being pinched and damaged. In addition, the detection switch is connected via a switch cover.
To the back set panel, so the detection switch can be directly
If the screw is too tight, such as when fixing the screw,
Therefore, the detection switch itself is not damaged. Sa
In addition, the detection switch is secured to the switch cover.
Since the holding part is formed, new wiring cover members etc.
To provide complicated components and complicate the configuration of the back-set board
Award that prevents cables from falling off with a simple configuration without any
A ball device can be configured. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described.
