Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a ball holder for a pachinko machine, in which three almost parallel dowels are installed at intervals in the lower part of the playing surface surrounded by the rails of the pachinko machine. It is installed in place of the chuck car, commonly known as the chuck car.

(Prior Art) A safe ball receiving device equipped with a pair of opening/closing wings called a tulip is sometimes used above the above-mentioned three chuckers spaced apart and almost parallel, but the ball receiving device is There is nothing that has the function of guiding the safe ball in a normal direction or in an advantageous direction by itself.

(Problems to be Solved by the Invention) The present invention uses a safe ball that is inserted into any one of three ball sockets arranged in parallel at intervals provided in the ball receiving device in place of the chucker commonly known as a dobon. The problem to be solved is to provide the ball receiving device itself with a function that allows it to sort the ball into a normal direction and an advantageous direction based on uncertain requirements.

(Means for solving the problem) The present invention aims to solve the problem mentioned in the previous section. Ball sockets arranged almost parallel to each other at intervals are connected to one ball processing chamber, and a plurality of long hole-shaped safe ball discharge ports are provided at the back of the ball processing chamber, and the ball discharge ports are A safe ball guiding path is provided that communicates with each of the safe ball guideways, and a rotary plate rotated by a motor is installed in front of the plurality of safe ball discharge ports, and a cut is made on the circumferential surface of the rotary plate from the peripheral wall of the ball processing chamber toward the center. A plurality of balls are inserted and rotated so as to sequentially match the respective discharge ports, and for some of them, the rear side is slightly lengthened in the direction of rotation to make it easier or difficult to enter any of the safe ball discharge ports. This invention relates to a ball holder device for a pachinko machine, which is characterized by being provided with a ball holder groove.

A preferred embodiment of the invention is described in the following section.

(Example) Fig. 6 shows an outline of this example, in which 1 is the pachinko machine body, 2 is a plywood board, and the rail 3
The ball receiving device a is located at the lower part of the gaming surface 4 surrounded by
At the center of the playing surface 4 is a pair of opening/closing pieces 6 whose opening/closing movements shown in solid lines and chain lines are controlled by an electric device such as a solenoid to make it easier or harder to hit balls. A piece 5 is provided.

The ball receiver device a includes a mounting plate 7 to the plywood board 2, and a ball receiver and ball processing piece 8 provided on the front surface of the mounting plate 7.
and a motor mounting piece 9 joined to the back side of the mounting plate 7.
The ball receiving and ball processing piece 8 has three ball receiving holes 10, 11, which are arranged almost in parallel and spaced apart from each other.
12 and a single circular ball processing chamber 13 below the central ball socket 11, and guide grooves 10a, 1 are provided in each of the ball sockets 10 to 12 and open to the inner surface of the ball processing chamber 13.
1a and 12a, a ball receiving groove 13a with a radius of about the radius of the ball A is formed on the lower side of the inner surface of the ball processing chamber 13, and a circumferential cover 14 with a slightly larger diameter is formed on the rear side of the ball processing chamber 13.
stand out.

A small reduction motor 15 is fixed to the center of the back side of the motor mounting piece 9, and a circular rotary plate 16 attached to the main shaft of the motor and rotates at a slow speed faces inside the circumferential cover 14 on the front side. A plurality of ball receiving grooves 17, 18 are cut into the peripheral edge of the plate 16 toward the center.
18 are formed at equal angular intervals, and between each ball receiving groove,
A push-up pin 19 is protruded into the ball processing chamber 13 and rotates while maintaining a distance slightly smaller than the diameter of the safe ball A between it and the circumferential cover 14 of the ball processing chamber. The motor mounting piece 9 has a ball socket groove 1.
Two safe ball discharge ports 20, 23, each having a slightly elongated hole shape in a circular direction, are formed in parallel in the upper part where the balls 7, 18, and 18 sequentially match and rotate, and the discharge ports 20,
23, as shown in FIG. 2, separate safe ball guideways 21 and 24 are provided to the right and left of the motor 15, and each time a safe ball A passes through each guideway, a passing signal is sent. Switches 22 and 25 for transmitting the signal are provided, and only the ball receiving grooves 18 and 18 have their rear sides that match the ball discharge ports 20 and 23 slightly longer in the rotational direction. 26 is a cover that covers the safe ball guideways 21 and 24.

(Function of this embodiment) Some of the balls flowing down the playing surface enter one of the ball sockets 10 to 12 and become safe balls A.
, the safe ball A is on the taxiway 10a to 12a.
Objects that are guided to the front surface of the rotary plate 16 by any of the push-up pins 19 are carried upwards and fall, while objects that are not caught by the push-up pins immediately fall. It enters the ball receiving groove 13a of the ball processing chamber 13. (Even when the ball receiving groove 13a is not provided, the balls accumulate in the lower part of the ball processing chamber 13.) Rotating plate 16
Since it is constantly rotating, the safe balls A accumulated at the bottom of the ball receiving groove 13a are either received by the ball receiving groove 13a or one by one enters one of the ball receiving grooves 17, 18, and 18. When the ball receiving groove matches the safe ball discharge port 20, most of the safe balls A flow into the safe guideway 21 and activate the switch 22, which removes the safe balls that failed to enter the safe ball discharge port 20. Ball A enters the safe ball discharge port 23, flows into the safe ball guide path 24, and operates the switch 25. Since the ball receiving grooves 18, 18 are slightly longer on the rear side in the direction of rotation, the ball can enter the safe ball discharge port 20 more easily than the ball receiving groove 17. Since the rotating plate 16 continues to rotate, the safe balls A that fail to enter either of the safe ball discharge ports 20 and 23 will be transferred from either the safe ball discharge ports 20 and 23 to the safe ball guiding path 21,
It flows out to one of 24.

The switch 22 generates a normal safe ball passage signal, and the switch 22 generates a signal for the opening/closing piece 6.
For example, the opening and closing movements are made twice at an interval of 2 seconds. The switch 25 generates a signal for passing the safe ball which is advantageous to the player, and the signal from the switch causes the opening/closing piece 6 to open/close 10 times at intervals of 3 seconds, for example.

(Effects of the invention) The present invention replaces the three chuckers commonly known as dobons placed at intervals at the bottom of the playing surface of a pachinko machine, and the safe balls inserted into any of the ball sockets 11 to 13 are The safe balls that have entered any of the ball sockets 11 to 13 are guided to the front surface of the rotating plate 16 of one ball processing chamber 13 by any of the guiding paths 10a to 12a, and are cut from the periphery of the rotating plate 16 toward the center. The balls are rolled one by one into the ball receiving grooves 17 and 18, and as the rotary plate 16 rotates, a plurality of safe ball discharge ports 2 are opened.
0 and 23 to flow down the safe ball guiding path 21 or 24, and some of the ball receiving grooves 17 and 18 have a slightly longer rear side in the direction of rotation. This makes it easier or harder for balls to enter the safe ball discharge ports 20 and 23, so it is possible to have a sorting action based on chance that cannot be manipulated manually, and this action can be achieved by the main ball receiving device itself. It has the effect of simplifying installation.
