Description

[Detailed description of the invention] The present invention relates to a safe hole device in a pachinko machine, and more specifically, the invention relates to a safe hole device for a pachinko machine, and more specifically, when a ball enters a predetermined safe hole, a rotating rod for preventing rotation of a shield plate is rotated via a solenoid, etc. The shielding plate of the safe hole provided in the board is temporarily freed, and the balls accumulated in the ball receiving frame protruding from the bottom surface of the safe hole are allowed to flow into the safe hole, thereby increasing the enjoyment of pachinko games. The aim is to double the amount.

Hereinafter, the present invention will be described in detail with reference to illustrated embodiments.

In the figure, 1 is a board with a case 2 provided on the back, and a safe hole 3 is provided in the center. Reference numeral 4 denotes a shielding plate for opening and closing the safe hole 3, and its upper end portion is pivotally attached to the back surface of the substrate 1 via a shaft 5 so as to be freely rotatable. Further, a projection 6 for preventing rotation of the shielding plate is provided on the back surface of the shielding plate 3. 7 is the protrusion 6
It is a rotating rod for supporting the board 1, and is rotatably attached to the upper wall 2a of the case 2 of the board 1 with a pivot 8. The rotating rod 7 has an upper end projecting outside the case from a notch 2a' provided in the upper wall 2a of the case, and is rotated via a solenoid (not shown) or the like. Moreover, the rotating rod 7 is always at its lower end due to its position near its lower end and a spring 9 tensioned on one side of the ball guide walls 2b, 2b vertically installed in parallel in the case 2 of the board. The portion is biased so that it is in a position where it comes into contact with the protrusion 6. Therefore, even if the rotating rod 7 is temporarily rotated via a solenoid or the like, when the solenoid stops operating, it is returned to the position where it comes into contact with the protrusion 6 again by the action of the spring 9.
Reference numeral 10 denotes a ball receiving frame that protrudes from the lower surface of the safe hole 3 to the front surface of the substrate 1 and is used to store balls of a number corresponding to the weights provided on the back surface. Further, the ball receiving frame 10 has a horizontally long flat plate shape, and is sloped so that the ball flows toward the safe hole 3. The ball receiving frame 10 is rotatably attached at its center to the back surface of the base plate 1 with a shaft 11, and a weight 12 is fixed to the back surface. The weight of the weight 12 is determined depending on how many balls are desired to be allowed to flow into the safe hole at one time. Reference numeral 13 denotes a passage for guiding the ball that has flowed into the safe hole 3, and includes guide walls 2b, 2b vertically installed in parallel in the case 2;
The guide wall 2c and the rear wall 2d of the case are suspended horizontally between them.
It is formed by. Reference numeral 14 denotes a safe hole of the same type as the conventional one, which is provided above the safe hole 3 in the substrate 1, and the safe hole does not need to be provided in particular. 15 is an obstacle nail. And this invention is the board 1
is placed at an appropriate location on the board so that it is parallel to the board. Note that 16 in the figure indicates a sphere.

The mode of operation of the present invention having the above configuration will be explained below.

As shown in Figure 1, a ball 16 that has fallen onto the ball receiving frame 10
is accumulated to the extent that it corresponds to the weight 12, but when it exceeds this amount, the ball receiving frame 10 rotates about the pivot 11,
(See Figure 4) All the accumulated balls fall. In addition, when a ball is accumulated and enters a predetermined safe hole, such as the safe hole 14 provided in the board 1, or another safe hole (not shown), the upper end of the rotating rod 7 is pressed via a solenoid (not shown), etc. and is rotated from the position shown by the solid line in FIG. 2 to the position shown by the imaginary line. Therefore, with this, the constantly rotating rod 7
The protrusion 6, which had been pressed against the back surface, is no longer supported, and the shielding plate 4 becomes free.
Pushed by the balls, it rotates about the pivot shaft 5 as a fulcrum as shown in FIG. 3, and all of the balls 16 accumulated in the ball receiving frame 10 flow into the inside of the safe hole 3. Further, the incoming ball is guided to the back side of the board through the passage 13 and becomes a safe ball. When the solenoid stops operating after a certain period of time has elapsed, the rotating rod 7 returns to its current position due to the action of the spring 9 and serves as a support for the protrusion 6. Note that while the shielding plate 4 is free, not only the balls accumulated in the ball receiving frame 10 but also the balls accumulated in the ball receiving frame 10 are
A ball falling upward also enters the safe hole 3, and if the operating time of the solenoid is set appropriately, it is possible to further increase the interest of the game for the player.

Since the present invention has the above-mentioned structure and function, it gives rise to the expectation that all the balls accumulated in the ball receiving frame will be safe balls, and at the same time, there is also the fear that all the balls accumulated until then will fall if they are not accumulated appropriately. The combination of expectations and anxieties can double the interest of the game.
Furthermore, by letting the ball enter a predetermined safe hole, not only the balls accumulated in the ball receiving frame 10, but also balls that later fall into the ball receiving frame 10 within a certain period of time can be treated as safe balls. It also has a sexual nature, and can make the player become absorbed in the game. In addition, since the structure is simple, it can be manufactured at low cost, and can be put to practical use with great effects.
