Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a prize ball release mechanism of a pachinko machine, and even if there are several prize balls that flow out with a delay, the prize balls will not flow into the drain gutter. It has an application in which the lever is slowed until the end to ensure that all prize balls are directed into the outflow gutter.

(Prior Art) In a pachinko machine, a lever is provided at the lower part of the prize ball discharge port, which swings due to the weight of the released prize ball, and communicates the tip with the outflow gutter as the lever swings. It is well known that one to a few prize balls that hit the lever a little later do not have enough weight to swing the lever, and this causes the tip of the lever and the outflow gutter to move backward. The problem is that the delayed ball gets caught between the illegal ball guiding gutter that blocks the upper part of the ball, preventing the lever from moving back, or causing the delayed ball to flow into the illegal ball guiding gutter.

(Problem to be solved by the invention) Accidents caused by late balls as described above occur only rarely, and especially when one or several late balls have flown into the illegal ball guiding gutter, they may go unnoticed. Ta. However, if there is an accident in which the lever does not move back, an employee must inspect and correct the problem, and if a delayed ball flows into the illegal ball guiding gutter, it will be a loss to the player, but the pachinko machine manufacturer There is not much interest in this, so we need to improve on this point.

(Means for Solving the Problems) The present invention aims to improve the above-mentioned drawbacks, and the sliding pin at the other end of the link piece connected to the lever and the cam groove as the lever swings. The present invention is characterized in that a guiding cam groove for a sliding pin that is induced to slide is provided, and a resistance portion that delays the sliding of the sliding pin is formed in the cam.

(Embodiment) A preferred embodiment of the present invention will be described with reference to the accompanying drawings.

Figures 1 and 2 show the prize ball release mechanism on the back of the pachinko machine, in which, for example, 15 prize balls a are stored in arc gutter-shaped prize ball cases 1 and 2 provided in two rows in the front and back.
The respective discharge ports 1a and 2a of the cases 1 and 2 are connected to the restraining claws 4 and 5 below the shaft 6 of the discharge control rod 3 operated by the lever.
The outlet 1a,
A lever 8 that swings about a shaft 9 is provided further below the guide trough 7 below the guide trough 2a. The lever 8 is connected to the left side of the shaft 9 (FIG. 1) with a connecting rod 10 that acts as a weight, and a weight may be attached in place of this connecting rod 10, but by doing so, the lever 8
is connected to the illegal ball guide gutter 11 by flipping up its tip, and when the prize ball a released from the release ports 1a and 2a rides on the lever 8, its gravity causes it to move toward the arrow x.
The tip 8a swings as shown in FIG.
It is designed to communicate with.

Further, the release control rod 3 is controlled by the locking claws 4, 5 by the lock portion 14a of the locking piece 14 which swings in the direction of the arrow y by the interlocking rod 13 which rises every time there is a winning ball.
from the discharge ports 1a and 2a to the right in Fig. 1,
As a result, prize ball a is released.

The prize ball release mechanism is not limited to the one shown in the drawings, and may have other configurations.

In the present invention, one end of a link piece 21 is pivotally connected to the lower part (or side part) of the lever 8 of the prize ball release mechanism, and a sliding pin 22 is provided at the other end of the link piece 21.
A guide cam 23 for guiding the sliding pin 22 is provided,
The guiding cam 23 is provided with a cam groove 23a, a part of which is curved in a meandering manner, as a resistance portion 24 so as to slow down the sliding speed of the sliding pin 22.

(Function) The present invention has the configuration as exemplified above, in which a winning ball is generated in the pachinko machine, the continuous rod 13, the locking piece 14, the release control piece 3, etc. are operated, and the prize ball a is released into the guide gutter 7. When this happens, the lever 8 that receives this lowers its tip 8a due to its weight and allows the water to flow into the outflow gutter 12. At this time, the sliding pin 22 also slides within the cam groove 23a and moves to the left in FIG. 3. At this time, the sliding pin 22 is forced to meander by the meandering cam groove 23a, so the energy of the weight of the prize ball a trying to push down the lever 8 is absorbed by the lever 8 and one end of the link piece 21. It is attenuated by the sliding frictional resistance between the shaft connection part and the resistance part 24, resulting in the effect of delaying the return movement.

Due to this delay, the release from the prize ball discharge ports 1a and 2a is slightly delayed, or the flow is slightly delayed while flowing through the guide gutter 7, and the ball is delayed in getting on the lever 8 together with the other prize balls a. Even if a' is placed on the lever 6 as shown in Fig. 3, it will not get caught in the inlet bottom plate of the irregular ball guide gutter 11 as in the conventional case, as shown by the chain line in Fig. It flows away into the outflow gutter 12.

(Effect of the invention) Due to the above-mentioned action, in the present invention, a very small number of the released prize balls a fall onto the lever 8 just before the return movement, and their weight is light because of the small number. The lever moves back without being acted upon, thereby eliminating the disadvantages of the ball a'' being jammed or flowing into the incorrect ball guide gutter 11.

In addition, the illegal ball guiding gutter 11 is installed at the end of the day.
It is also used to discharge the remaining balls to the back of the Pachinko machine while the lever 8 is kept inactive.
