Description

[Detailed description of the invention] This invention relates to a safe ball receiving device for a pachinko machine that opens and closes the window by raising and lowering the upper guide plate within the window hole of the board to increase or decrease the chances of a ball being hit as a safe ball. In particular, the locking plate that locks the locking part of the special guide plate that opens and closes by raising and lowering the upper guide plate and closing the window hole accidentally comes off due to movement etc. due to cheating by the player. To provide a safe ball receiving device for a pachinko machine, in which a locking plate can be attracted and held by a magnet to prevent the balls from falling.

The safe ball receiving device of this invention will be explained below based on an embodiment shown in the drawings.

In Figures 1 to 5, 3 is a synthetic resin substrate with a rectangular window hole 1 in its center, and a safe ball introduction plate 2 at the center of its lower part for introducing safe balls into a central discharge passage 4 rearward from the front surface. will be established.

Reference numeral 6 denotes a back case made of synthetic resin, with a central safe ball discharge passage 4 provided at the center of the back surface, and downward safe ball lateral discharge passages 5, 5 on both sides thereof.

This rear case 6 is attached to the base plate 3, the safe ball introduction plate 2 of the base plate 3 faces the central discharge passage 4 of the rear case 6, and the safe balls are rolled on the introduction plate 2 to the central discharge passage. 4
It will be discharged to

Reference numeral 10 denotes a ball guide plate made of resin, which is supported by pivots 15 and 15 on both sides of the lower part of the window hole 1 of the board 3 with its center of gravity shifted forward, and at the center of the lower part of the upper guide plate 10. A safe ball introduction lower is bored in the upper guide plate 10 so that the safe ball can be transferred onto the safe ball introduction plate 2 of the board 3, and safe ball introduction protrusions are provided on both sides of the front side of the safe ball introduction lower of the upper guide plate 10. 8, 8, and dividing walls 9, 9 are formed on both sides of the back side to divide the back side of the upper guide plate into three passages A, A', and A'', and the two side passages A and A/ / is provided with standing edges 16, 16 at the lower end thereof, and one of the partition walls 9 is provided with a locking portion 11 at the rear of the lower end.
form a protrusion.

12 is a type 1 locking plate that has a locking piece 17 formed in the center and a jump portion 18 at its lower end, and the upper front end of this locking plate 12 is rotatably supported by a shaft 19 in a slot 20 of the rear case 6. The lower end of the locking plate is always inclined forward due to its own weight, and the locking plate is attached to the central discharge passage near the rear end of the safe ball introducing plate 2.
When the upper guide plate 10 or the safety ball is rotated to stand it up, the locking piece 17 of the locking plate is once pushed backward by the locking part 11 of the partition wall 9, and the locking part 11 locks. At the position below the piece 17, the locking plate returns by its own weight, and the locking portion receives the locking piece, thereby holding the upper guide plate in an upright position.

When the safe ball moving on the safe ball introducing plate 2 bounces the jumping part 18 of the locking plate, the locking piece and the locking part are disengaged and the upper guide plate is tilted forward.

A suction rod 13 is provided on the upper side of the locking plate 12, and a magnet 14 is provided on the back case 6 so that the suction rod of the locking plate is always attracted and held by the magnet.

In the embodiment, a screw is provided as the suction rod 13, and the magnet 14 is provided with its upper portion exposed on the back surface of the back case 6.
It is designed to directly attract screws.

In the embodiment, the upper front end of the back case 6 is hooked into the window hole 1 of the board 3, and the lower end is tightened with a screw 21, but the structure is of course not limited to this.

Also, safe ball guide plates 22, 22 are provided on both sides of the window hole 1 of the base plate 3 to facilitate the introduction of balls when the upper guide plate 10 is tilted forward.

Furthermore, a protruding shaft 23 is formed on the other side of the upper part of the locking plate 12,
One end of the lever rod 24, which is pivotally supported at the rear of the rear case 6, is always in contact with the protruding shaft, and when the other end is pushed down with a safe ball etc. from another safe ball receiving port, the locking plate is locked. This is to release the lock between the piece and the locking portion of the upper guide plate.

25 is a stopper of the lever, and 26 is a safe ball guiding protrusion.

Reference numeral 27 denotes a receiving case integrally formed with a safe ball introduction plate 2 that projects from the center of the lower front surface of the window hole 1 of the base plate 3, and on both sides of the introduction plate 2 there are safe ball guide protrusions when the upper guide plate 10 is in the forward tilted state. 8
, 8 is provided.

Further, the safe ball introduction plate 2 is formed in an inclined shape from the upper part of the front end of the receiving image 27 toward the rear central discharge passage 4.

Since this device has the above-mentioned structure, its operation will be explained. When the upper guide plate 10 is in the upright state and closes the window hole 1, the safe ball between the safe ball introducing protrusions 8, 8 of the upper guide plate When a safe ball enters the inlet 7, the top of the safe ball introduction plate 2 is moved to the rear safe ball central discharge passage 4, and the jump portion 18 of the locking plate 12 facing the passage is moved by the weight of the locking plate itself and the magnet. The upper guide plate 10 rotates forward under its own weight by springing against the adsorption force of the locking piece and the locking part of the upper guide plate, opening the window hole 1 and closing the upper guide plate. Three passages A on the back side of
This opens A' and A".

The hit ball is then transferred onto the ball guide board using a safe ball guide board or the like.

When a ball enters the center passage A' and becomes a safe ball, it rolls on the safe ball introducing plate 2 and is ejected to the central discharge passage 4, pushes the locking plate 12 and falls downward, so the upper guide plate It remains as it is.

Passage A on both sides. When a ball hits A" and becomes a safe ball, it rolls along the path, pushes down the upright protrusion 16 with the weight of the safe ball, rotates the upper guide plate 10 in the upright direction, and moves the special guide plate. The locking portion is locked to the locking rod of the locking plate, and together with the action of the magnet, the upper guide plate is stably held in an upright position.

According to this invention, the locking plate that locks the locking part of the special guide plate with the upper guide plate erected and the window hole closed is attracted and held by a magnet, so that the player can hold the pachinko machine board on the front side by hand. The locking plate does not move inadvertently due to vibrations such as tapping, and the locking state of the locking part and the locking piece can be reliably maintained, and the locking plate will not move upwards only when the safe ball is transferred properly. The information board can be opened.

In addition, since the protruding shaft of the attracted locking plate hangs over one end of the lever, vibration of the lever can be suppressed and the locking plate can be prevented from operating indiscriminately.
