Conventionally, as shown in FIGS. 6 and 7, the operation handle 100 of the electric pachinko machine includes a fixed base member 101 attached to the pachinko machine side, and a rotary handle 102 rotatably attached to the base member 101. A rotary shaft 103 that passes through the center of the rotary handle 102 and transmits the rotational force of the rotary handle 102 to the back side of the pachinko machine, and a fixed cap member 104 that is connected to the base member 101 with the rotary handle 102 interposed therebetween. In general, the striking force of the launch ball is adjusted by adjusting the amount of rotation of the rotary handle 102. The rotary handle 102 and the rotary shaft 103 form a non-circular shaft hole 105 in the rotary handle 102, while the cross-sectional non-circular portion 106 matches the shaft hole 105 of the rotary handle 102 at the end of the rotary shaft 103. A groove 108 for the E ring is formed, and the non-circular portion 106 of the rotary shaft 103 is formed into a shaft hole from the back side of the rotary handle 102 (the side facing the front frame of the pachinko machine) as shown by a two-dot chain line in FIG. The E-ring 107 is inserted into the groove 108 of the rotating shaft 103 protruding from the front side of the rotary handle 102 so as to be prevented from coming off.
[0003]
[Problems to be solved by the invention]
In the conventional structure in which the E-ring 107 is fitted to the rotation shaft 103 to prevent the E-ring 107 from being removed, the workability and the productivity are lowered because the E-ring 107 is troublesome first, and the E-ring 107 is used second. There were problems such as the cost of parts rising by the amount.
[0004]
The present invention has been made in view of the above, and an object of the present invention is to provide an operation handle for an electric pachinko machine that does not require the use of an E-ring and can be easily attached to a rotating shaft.
[0005]
[Means for Solving the Problems]
To achieve the above object, the present invention provides a fixed base member attached to the pachinko machine side, a rotary handle rotatably attached to the base member, a rotational force of the rotary handle passing through the center of the rotary handle. And a fixed cap member connected to the base member across the rotary handle, and by adjusting the amount of rotation of the rotary handle, the striking force of the launch ball In the operation handle of an electric pachinko machine that adjusts the
The rotating shaft has a main shaft portion, and a shaft head formed at an end portion of the main shaft portion on the cap member side,
The shaft head is formed integrally with the main shaft portion before being attached to the rotary handle in a shape that does not pass through the rotary shaft insertion shaft hole provided in the rotary handle ,
The main shaft portion has a shape capable of passing through the shaft hole of the rotary handle,
The main shaft portion is inserted into the shaft hole of the rotary handle from the cap member side toward the base member side, and the movement of the rotary shaft to the back side of the pachinko machine is restricted by the hook of the shaft head with respect to the shaft hole. On the other hand, an operating handle for an electric pachinko machine is provided in which the receiving portion of the cap member faces the end face of the shaft head of the rotating shaft so that movement in the opposite direction of the rotating shaft is restricted .
[0006]
In the above-mentioned operation handle, since the axial head of the rotary shaft is sandwiched between the rotary handle and the cap member and the movement in the axial direction is restricted, an E-ring for preventing the rotary shaft from coming off from the rotary handle can be eliminated. Moreover, if a cap member is attached to a base member, a rotating shaft can be fixed.

A front-facing L-shaped link member 3g that has a tip facing the actuator piece 3d, engages the claw piece 3e with the rotary handle 4 and swings about the shaft 3f, and a shaft cylinder portion 3h through which the rotary shaft 6 passes. And support cylinder portions 3j, 3j, 3j for supporting the cap member 7 are provided.
[0010]
The rotating handle 4 has a circular shaft hole 4a provided for passing the rotating shaft 6, and two guide holes 4b, 4b drilled in an arc around the shaft hole 4a. The support cylinder part 3j of the function part 3a is made to face the guide holes 4b and 4b over the front of the function part 3a. Further, the rotary handle 4 is provided with a receiving tube 4c in which a shaft head 6b, which will be described later, of the rotary shaft 6 is accommodated, and further provided with convex portions 4d, 4d, 4d for hooking on the outer periphery.
[0011]
The rotating shaft 6 is made of metal or synthetic resin, and is formed at a main shaft portion 6a having a uniform thickness, a shaft head 6b formed at one end of the main shaft portion 6a, and the other end of the main shaft portion 6a. It consists of the engaging part 6c. The shaft head 6b has a non-circular cross section in which a cylinder having a diameter larger than that of the main shaft 6a is used as a basic shape and a part of the cylinder is cut flat.

A round bar may be used, and the main shaft portion 6a may be provided with a flat surface portion 6d to have a non-circular cross section. In this case, the shaft hole 4a of the rotary handle 4 is in a non-circular shape that matches the main shaft portion 6a, and the receiving cylinder 4c of the rotary handle 4 is not required as shown in FIG. It becomes a shape (see the rotating handle 102 in FIG. 6). Accordingly, the structure of the rotary shaft 6 and the cap member 7 may be slightly changed, and the cost can be reduced by using a conventional operation handle mold.
[0017]
Further, the bearing means 9 provided between the receiving portion 7d of the cap member 7 and the shaft head 6b of the rotating shaft 6 is not limited to the configuration provided on the receiving portion 7d side as in the embodiment, but is shown in FIG. In this way, the end surface of the shaft head 6b of the rotary shaft 6 may be a mountain shape that rises toward the center, such as a conical shape or a hemispherical shape, or a structure in which a short axis such as a cylindrical shape or a hemispherical shape protrudes. . Furthermore, the operation handle 2 is not limited to the one that is directly connected to the spring force adjusting pulley 5 to adjust the hitting force of the shot ball. For example, the rotation angle of the rotary shaft 6 is converted into an electric signal to launch the shot hitting device. It can also be used to increase or decrease the motor torque.
[0018]
