Abstract

PROBLEM TO BE SOLVED: To reduce a wiring amount, to simplify the structure of a tray door and to prevent disconnection. SOLUTION: Since a ball feeding mechanism 52 is arranged on the back surface of the tray door 36 provided with an upper tray 38, and a solenoid 82 for driving it is disposed on the machine body side of a Pachinko machine 20, wiring to the solenoid 82 is limited only to the machine body side. As a result, the need for performing wiring to the tray door 36 is eliminated and the structure of the tray door 36 is simplified. Also, the wiring amount for the entire Pachinko machine 20 is reduced. Further, the danger of bending and degrading the wiring of the solenoid 82 accompanying the opening and closing of the tray door 36 is eliminated as well.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of a ball-and-ball game machine, and more particularly, to a launching ball supply device for feeding game balls one by one onto a launching rail.

[0002]

2. Description of the Related Art In a ball-and-ball game machine such as a pachinko machine, a game is played by hitting a game ball placed on a firing rail by a firing device and hitting the ball on a game board. Therefore, there is a need for a launching ball supply device for sending out game balls one by one onto a launching rail. The launching ball supply device can be roughly classified into a device that receives a driving force from a hitting ball hammer (a device that does not have its own driving source) and a device that includes a driving source such as a solenoid.

[0003]

The present invention relates to the latter technique. Conventionally, however, a mechanism for sending out firing balls one by one and a solenoid or the like serving as a driving source are both installed on the supply plate side (the back of the plate door). (For example, JP-A-6-312045). When these were installed together on the back of the dish door, it was necessary to route power wiring and control wiring from the main body of the ball game machine to the dish door. Therefore, the amount of wiring is large, the structure of the dish door may be complicated, and the wiring may be broken due to repeated bending accompanying opening and closing of the dish door.

[0004]

Means for Solving the Problems and Effects of the Invention
The launching ball supply device described above is a launching ball supply device that is mounted on a ball game machine and sends out game balls supplied from a supply tray one by one onto a launching rail.
A solenoid disposed on the main body side on which the firing rail is mounted, with the direction of movement of the plunger substantially parallel to the front-rear direction of the ball game machine, and the solenoid mounted on the back of a plate door provided with the supply plate. Since it is constituted by the ball-sending mechanism driven by the motor, there is no need to route power wiring and control wiring to the solenoid to the dish door. Therefore, the amount of wiring of the ball game machine can be reduced, the structure of the dish door is simplified,
There is no danger that the wiring will be broken due to the repetition of bending caused by the opening and closing of the dish door.

In addition, the ball feeding mechanism has an inlet and an outlet of the game ball, a convex portion for preventing the game ball flowing from the inlet from moving to the outlet, and a swing shaft parallel to the width direction of the dish door. And a rocking body capable of swinging displacement about a swing axis between a stop position and a sending position, wherein the stop position allows movement of the game ball from the entrance to a position stopped by the projection, When pressed by the plunger protruded when the solenoid is energized, the position changes from the stop position to the delivery position, and pushes up the game ball that is prevented from moving by the convex portion to get over the convex portion and The swinging body for holding the game ball at the entrance side and the spring for biasing the swinging body toward the stop position side are provided, so that the moving direction of the plunger is substantially parallel to the front-rear direction of the ball game machine, ~ side It can be satisfactorily driven by a solenoid which is arranged. As the plunger moves back and forth,
The installation area of the solenoid can be smaller than when the plunger moves in the left-right direction of a ball game machine, for example.

According to a second aspect of the present invention, there is provided a launching ball supply device according to the first aspect, wherein the rocking member also serves as a member for supporting a game ball stopped by the projection. The number of members to be used can be reduced correspondingly. According to a third aspect of the present invention, there is provided a launching ball supply device according to the first or second aspect, wherein the solenoid is disposed below the firing rail. In the past, a part of the lower part of the firing rail was sometimes used as a return path for foul spheres, but it was rarely used for other purposes. Since this unused space is used as a place for installing the solenoid, there is no need to restrict the space for installing other parts for the solenoid or to move other parts, etc. Will be used.

As shown in FIG. 5, an inlet 54a and an outlet 54b are provided in a case 54 of the throwing mechanism 52.
A passage plate 56 is provided inside the outlet 54b, and an inner end 56a thereof corresponds to the projection. Further, a step 58a is provided on a back plate 58 which also serves as a floor of the entrance 54a.

A swing shaft 60 is provided below the passage plate 56 along the width direction of the dish door 36, and the swing body 62 is supported by the swing shaft 60. The oscillating body 62 includes a cut-off portion 64 extending from the bearing portion 63 through which the oscillating shaft 60 passes, in the direction of the back plate 58, and a pressure receiving portion 66 hanging downward from the bearing portion 63. The swing body 62 is urged in the counterclockwise direction in the figure by a spring 67 loosely fitted to the swing shaft 60.

Therefore, in a situation where only the urging force of the spring 67 acts, the rocking body 62 is at the position shown in FIG. 5A, in which case the tip of the cut-off portion 64 is supported by the step 58a. ing. A buffer 64a such as urethane rubber is attached to the lower end of the cut-off portion 64, for example.

In the state shown in FIG. 5 (a), no step is formed between the upper surface of the back plate 58 and the upper surface of the leading end of the cut-off portion 64, and almost no step is formed from the entrance 54a to the upper corner 64b of the cut-off portion 64. It becomes a series of planes. However, it is slightly inclined from the entrance 54a toward the upper corner 64b. The inner end 56a of the passage plate 56 is located above an extension of this plane. The cut-off portion 64 is bent downward from the upper corner 64b, and a gap is formed between the upper corner 64b and the inner end 56a. Therefore, the game ball B1 flowing from the entrance 54a is prevented from moving toward the exit 54b by the inner end 56a of the passage plate 56, and between the upper corner 64b and the inner end 56a as shown in FIG. Stop.

On the other hand, as shown in FIG. 5B, for example, when an external force is applied to the hemispherical pressure receiving projection 66a provided on the pressure receiving portion 66 and the oscillator 62 is displaced clockwise,
The cut-off portion 64 is displaced upward about the swing shaft 60 and pushes up the game ball B1 near the upper angle 64b, and the inner end 56a
Get over. Gaming ball B over the inner edge 56a
1 is discharged from the outlet 54b.

At this time, if there is a subsequent game ball B2 that is about to flow in from the entrance 54a, it is prevented from approaching at the tip of the rising cut-off portion 64. And the rocking body 62
Returns to the position of FIG. 5 (a), the subsequent game ball B
2 advances and newly occupies the position of the game ball B1.

With such a structure, the throwing mechanism 52
The game ball can be taken in and released one by one every reciprocation of the rocking body 62. The driving source of the oscillating body 62 is the above-described solenoid 82, and the launching ball supply device 85 is configured by the ball feeding mechanism 52 and the solenoid 82. The center of the plunger 83a is set to penetrate the center of the pressure receiving projection 66a.

When the solenoid 82 is off, the plunger 8
3a is retracted as shown in FIG. 5 (a) and does not contact the pressure receiving projection 66a. When the solenoid 82 is energized, the plunger 83a is protruded and the plunger head 83 presses the pressure receiving projection 66a. Then, the rocking body 62 is rocked and displaced clockwise as described above (FIG. 5).
(From FIG. 5A to FIG. 5B). Along with this, the inner end 5 is pushed up near the upper corner 64b of the cut-off portion 64.
The game ball B1 that has passed over 6a is released from the exit 54b and falls on the firing rail 76. The subsequent game ball B2 that is about to flow in from the entrance 54a is prevented from entering at the leading end of the rising cut-off portion 64.

When the solenoid 82 is turned off,
The plunger 83a is retracted and the plunger head 83
Is released, so that the rocking body 62 is
5A is returned to the position shown in FIG. As a result, the subsequent game ball B2 advances and newly occupies the position of the game ball B1.

As described above, when the solenoid 82 is turned on, one game ball is released onto the firing rail 76. When the solenoid 82 is turned off, one game ball is taken in from the entrance 54a. By this repetition, game balls can be supplied one by one onto the firing rail 76.

It is necessary to synchronize the supply of the shooting ball onto the shooting rail 76, that is, the turning on and off of the solenoid 82, with the hitting operation of the game ball shooting device 80. In this embodiment, a shooting control device (not shown) is used. The game ball launching device 80 and the solenoid 82 are controlled.

When the player operates the firing handle 46, the game ball firing device 80 operates. This game ball launching device 80
The throwing mechanism 52 is driven in synchronization with the operation of the
, The game balls are introduced one by one, and dropped on the firing rail 76. The game ball is hit by the game ball launching device 80 and is hit on the game board 26, and a pachinko game is performed by the behavior of the game ball there.

In the pachinko machine 20 of this embodiment, the ball feeding mechanism 52 is disposed on the back of the dish door 36 having the upper plate 38, and the solenoid 82 for driving the mechanism is arranged on the main body side of the pachinko machine 20. The wiring to the solenoid 82 is limited to only the main body. As a result, there is no need to wire the dish door 36, and the structure of the dish door 36 can be simplified and simplified. Also, the amount of wiring of the entire pachinko machine 20 can be reduced. Further, there is no possibility that the wiring of the solenoid 82 is bent or deteriorated with the opening and closing of the dish door 36.

Although the embodiment of the present invention has been described according to the embodiment, the present invention is not limited to this embodiment.
