Description

[Detailed description of the invention] In this invention, in order to fit the back of the mounting plate of the safe ball socket and to attach the mounting plate to the front of the game board (veneer board), the mounting hole provided in the game board is For convenience of hole forming, the bottom of the mounting hole is also
This invention relates to a safe ball receptacle for a pachinko machine that can cope with the tendency for balls to be formed at right angles to the front surface.

Conventionally, the mounting hole that was formed to fit the back of the mounting plate of the safe ball socket into the game board was made by sloping the bottom of the hole downward toward the rear side, as shown by the dotted line in Figure 2. It was designed so that the balls would flow out to the rear of the game board x without stagnation. However, in order to do so, pass a woodworking router through the front or back side of the game board x at right angles and drill a mounting hole of the required shape.
Since the game board x was fixed diagonally and the above-mentioned slope was formed using the woodworking router, forming the mounting holes required at least two steps, which was inefficient.
For this reason, as shown in FIGS. 7 and 8, there has been a tendency to omit the forming process so that no slope is formed on the bottom surface c of the mounting hole b. However, in this case, since the peripheral wall including the bottom surface c of the mounting hole b becomes a rough surface with the wood grain cut away, the ball that is not in the force of the ball _a1 that enters the hole b will be As shown in the figure, a drawback has arisen in that some particles remain on the bottom surface c and cannot be diverted to the rear. The present invention aims to eliminate such drawbacks by improving the safe ball socket itself.

Figures 1 to 4 show an example of a conventionally used safe ball receptacle. A pair of opening/closing vanes are pivotally supported by shafts 4, 4 provided on both sides of the ball inlet 2, and 5 is a chucker fixed to the mounting plate 1 below the opening/closing vanes 3, 3.
As shown in FIG. 2, a portion of the front surface of the opening/closing vanes 3, 3 is also covered. Reference numeral 6 denotes a box frame mounted on the back side of the mounting plate 1 to cover both sides of the ball inlet 2, and the front end protrudes from the ball inlet 2 by means of a horizontal shaft 7 extending behind the box frame, and an opening/closing wing plate 3 is mounted on the back side of the mounting plate 1. , 3, and a second horizontal shaft 1 below the horizontal shaft 7.
The lock piece 11 is pivotally supported at 0. The lock piece 11 has a receiving surface 12 located behind the horizontal axis 7 of the ball guide plate 8, and a receiving surface 12 that receives the ball a flowing backward on the ball guide plate 8 and causes it to flow out from the side of the box frame 6. A locking hole 13 is formed in the side surface of the guide plate 8 into which a pin 9 is fitted, and the ball guide plate 8 is locked and received so that the front end does not spring up in the attitude shown in FIG. Side 1
When the ball is hit by the ball a, it swings as shown in Fig. 4 due to the weight of the ball, and at the same time, the front end of the ball guide plate 8 moves up in an interlocking manner. Lock the front end to prevent it from falling down. This lock piece 11 is provided with a hanging piece 14 extending downward from the front part of the second horizontal shaft 10, as shown in FIG. A piece 15 is provided. This ball receiving piece 15 is an opening/closing blade that tilts when the ball a enters as shown in the arrow in Figure 2 and the ball guiding plate 8 and locking piece 11 spring up as shown in Figure 4. 3,
3 swings as shown in the figure, and is then pushed by the ball _a1 passing between the opening and closing vanes 3, 3, causing the lock piece 11 and the ball guiding plate 8 to move to the posture shown in FIG.

The present invention is based on the above-mentioned known structure.
A guide plate 16 is integrally provided on the rear side of the guide plate 16, which is horizontal in the attitude shown in FIG. 2 or whose rear part is slightly lowered. (See Fig. 6) As shown in Fig. 5, the safe ball receiving device has a ball guide plate 8a extending to the rear of the horizontal shaft 7a and a receiving surface 12a at the rear end thereof. ni tatagata 1
4a and is provided with the same ball receiving piece 15a as described above, and in this case also, a guide plate 16a is integrally provided on the rear side of the ball receiving piece 15a. (See Figure 6) The guide plate 16 moves on the bottom surface c of the mounting hole b formed perpendicularly to the front surface of the game board The ball protrudes or approaches the back surface and causes the ball _a1 flowing backward on the ball receiving piece 15 to flow out to the back surface of the game board x without coming into contact with the bottom surface c of the mounting hole b. The guide plate 16a shown in FIG. 5 also performs the same function.

As clarified from the above explanation, the present invention is designed to prevent a ball from entering when the opening/closing blades 3, 3 are tilted.
a ₁ hits the ball receiving pieces 15, 15a, thereby causing the locking piece 11 of the ball guide plate 8 or the front end of the ball guide plate 8a to be pushed down, and the opening/closing wing plate 3 being erected by the passage of the ball a ₁ . , 3, in which the front ends of the ball guiding plates 8, 8a are interposed below the axis of the ball guide plates 8, 8a to maintain the upright position. Hitting ball a flowing backwards on each side
The ball is made to flow on the guide plates 16, 16a without coming into contact with the bottom surface c of the mounting hole b, and flows out to the rear surface of the game board Even if c has a horizontal shape that impairs the flow of balls, the drawbacks caused by this can be solved with the safe ball socket itself, and the installation of the safe ball socket on the game board x is completely different from before. It is something that does not change.
