Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a ball handle suitable for a pachinko machine commonly called an arrangement pachinko.

(Prior Art) The ball device of a normal electric pachinko machine has a built-in touch switch circuit that operates the ball motor only when the player touches the dial plate of the ball handle. Since the entire surface of the ball is made of conductive material, the ball will fire continuously while the handle is held, unless the stop button is pressed. However, the lower part of the game board is equipped with many pockets, and prizes are given out when the lamps on the display section in, for example, 4 x 4 rows, which are arranged according to the numbers of the pockets containing balls, light up in a specific arrangement. In so-called arrangement pachinko machines, it is mandatory to use a ball device that can reliably fire balls one by one, so a device with a metal plate embedded in the adjustment lever so that only the electrode part is exposed on the surface is required. Are known. (Utility Model Publication No. 144676/1983) (Problems to be solved by the invention) However, the above-mentioned adjustment lever made by embedding a metal plate has a poor operating feel because it is heavy. Not only does the touch feel not good because the electrodes are touched, but if the metal electrodes corrode due to sweat, the entire adjustment lever must be replaced, which increases running costs. There was also the problem of high manufacturing costs due to the inclusion molding.

This invention was completed with the aim of solving the above-mentioned conventional problems and creating an electric pinball handle that can reliably fire balls one by one and can be attached to arranged pachinko machines. It is something that

(Means for Solving the Problems) The present invention, which was made to achieve the above object, has a U-shaped cross section on the back side of a synthetic resin dial plate fixed to the front part of a metal handle shaft. A conductive plate made of synthetic resin with conductive plating is installed inside the dial plate, and a part of this dial plate is cut out and a touch part made of synthetic resin with conductive plating is attached so that its tip reaches the conductive plate.
The touch part and the conductive plate were connected by screws, and the conductive plate and the handle shaft were connected by a lead wire, and further connected to a touch switch circuit that drove the ball motor only when the handle shaft was electrically connected to the human body. It is characterized by this.

(Embodiments) Next, the present invention will be described in detail with reference to illustrated embodiments.

1 is a synthetic resin handle base fixed to the front of the game board; 2 is a rotatable metal handle shaft passing through the center of the handle base 1; 3 is a flange portion 4 at the front of the handle base 1; A rotatable synthetic resin dial plate located on the front of the 5
is a synthetic resin dial cap fixed to the flange portion 4 of the handle base 1 with screws 6. A rotation preventing portion 7 is formed at the front portion of the handle shaft 2, and the dial plate 3 described above is fixed to this portion so that it cannot rotate relative to the handle shaft 2. This dial plate 3 is similar to the conventional dial plate in that it is equipped with a circumferentially extending through hole 8 for passing the screw 6, but the entire surface of the conventional dial plate is made of a conductive material. On the other hand, the present invention differs greatly in that the entire surface is made of synthetic resin. The back surface of this dial plate 3 has a U-shaped cross section, and a conductive plate 9 is attached with screws 10 at a position inside the dial plate 3 where there is no risk of it coming into contact with fingers when the handle is gripped by hand. . The conductive plate 9 is a synthetic resin plate whose entire surface is conductive plated.

Reference numeral 11 designates a conductive touch portion attached only to a portion of the surface of the dial plate 3. Preferably a finger rest protrusion 12 of the dial plate 3
A portion that is easy to touch with a fingertip, such as , is cut out toward the inside, and the touch portion 11 is attached to this cutout. This touch part 1
1 is also a synthetic resin surface with conductive plating, the tip 13 of which protrudes from the back surface of the dial plate 3 through the notch of the dial plate 3, and is connected to the conductive plate 9 by the screw 10 mentioned above. has been done. The other end of the conductive plate 9 is connected to the tip of the handle shaft 2 by a lead wire 16 having terminal plates 14 and 15 at both ends. The handle shaft 2 is connected to a known touch switch circuit that drives the ball motor only when it is electrically connected to the human body, as in the prior art.

(Function) The device configured in this way has a finger rest protrusion 12 on the dial plate 3, similar to the conventional ball handle.
The handle shaft 2 is rotated by placing one's finger on the handle and rotating from side to side, thereby adjusting the strength of the ball and firing the ball. However, unlike the conventional ball handle of the present invention, the surface of the dial plate 3 is made of non-conductive synthetic resin except for the touch part 11 which is made of synthetic resin with conductive plating.
Simply grasping the ball with your hand will not fire the ball, but only when you touch the conductive touch part 11 with your fingertip will the ball be fired via the synthetic resin conductive plate 9 with conductive plating on the back of the dial plate 3. 2 and the human body, the touch switch circuit is activated, and the ball motor is activated. Therefore, the player touches the ball by touching the touch part 11 for a very short time.
By repeating the action of firing only one ball, then rotating the dial plate 3 and touching the touch part 11 again to fire the second ball, you can reliably aim the balls one by one at the targeted pocket. It becomes possible to fire.

(Effect of the device) As is clear from the above explanation, the device of the present invention is capable of reliably firing balls one by one to the desired position by repeatedly touching the touch part with the fingertip. It is suitable as a ball handle for a type pachinko, and since the conductive plate is made of synthetic resin with conductive plating, it is easier and cheaper to mass produce than when metal plates are embedded. In addition to being able to manufacture the handle without using metal, it is made entirely of synthetic resin, making it lightweight and giving a good feel of dial operation. Because they are connected, it is easy to replace just the conductive plate. Moreover, the touch part is constructed separately from the conductive plate, and is attached to the notch in the dial board and fixed with screws, so if the touch part becomes damaged due to sweat, you can simply replace the touch part and save on running costs. In addition, since the conductive plate is attached inside the dial plate with a U-shaped cross section on the back side, there is no risk of accidental contact when the player grasps the handle, and has various other advantages. It is something.

Therefore, the present invention has extremely great practical value as it solves the problems of conventional ball handles.
