Consists of

The base member 3 includes a shallow cup-shaped function part 3a and a mounting cylinder part 3b integrally projecting therefrom. The function part 3a has a microswitch 3c for turning on / off the hitting ball launcher, A shaft passing through the rotary shaft 6 and a substantially L-shaped link member 3g, the front end of which faces the actuator piece 3d of the microswitch 3c, engages the claw 3e with the rotary handle 4, and swings about the shaft 3f. A cylindrical portion 3h and a supporting cylindrical portion 3 for supporting the cap member 7
j, 3j, and 3j.

The rotary handle 4 has a circular shaft hole 4a provided for passing the rotary shaft 6, and two guide holes 4b, 4b formed in an arc around the shaft hole 4a.
The supporting cylinder 3j of the functional part 3a is made to face the guide holes 4b, 4b so as to cover the front of the functional part 3a of the base member 3.
The rotating handle 4 has a shaft head 6 (described later) of the rotating shaft 6.
A receiving cylinder 4c for accommodating b is protruded, and furthermore, convex portions 4d, 4d, 4d for finger hanging are provided on the outer periphery.

The rotary shaft 6 is made of metal or synthetic resin, and has a uniform thickness main shaft portion 6a, a shaft head 6b formed at one end of the main shaft portion 6a, and the other end of the main shaft portion 6a. And an engaging portion 6c formed at the bottom. The shaft head 6b is the main shaft 6
It has a non-circular cross section in which a cylinder having a diameter larger than a is used as a basic shape and a part of the cylinder is cut flat. The engaging portion 6c is formed by cutting off the end of the main shaft portion 6a flat, and is engaged with the pulley 5 for adjusting the spring force so as to be freely inserted and removed.

The cap member 7 includes a hollow hemispherical cap main body 7a, a disk-shaped plate 7b for closing an opening of the cap main body 7a, and screw cylinder portions 7c, 7c, 7c protruding from the plate 7b. And The cap member 7 covers the front surface of the rotary handle 4 and fits the screw tube portion 7c into the support tube portion 3j of the base member 3, and further tightens the screw 8 passed through the screw tube portion 7c from the base member 3 side. To be integrated with the base member 3. In the center of the plate 7b, an upright receiving portion 7d facing the shaft head 6b of the rotary shaft 6 is provided, and a hemispherical, cylindrical, or conical shape is provided at the center of the receiving portion 7d. The bearing means 9 is provided in the form of a small projection, such as in the form of a small projection, or a chevron-shaped or conical shape in which the entire surface of the receiving portion 7d is raised toward the center.

Since the operating handle 2 of the present invention is configured as described above, the assembling is performed by attaching the rotating handle 4 to the base member 3 and passing the main shaft 6a of the rotating shaft 6 into the shaft hole 4a of the rotating handle 4. The shaft head 6b is fitted to the receiving cylinder 4c, the cap member 7 is put on the front surface of the rotary handle 4, and the cap member 7 and the base member 3 are tightened with screws 8.

In the assembled state, the rotating shaft 6
Since the shaft head 6b is sandwiched between the rotary handle 4 and the cap member 7, the movement in the axial direction is restricted,
The rotating shaft 6 does not come off, and the rotating shaft 6 can be inserted into and removed from the spring force adjusting pulley 5 as before.

When the rotary handle 4 is turned while attached to the pachinko machine, the rotary shaft 6 rotates together with the fitting of the receiving cylinder 4c and the shaft head 6b, so that the spring force adjusting pulley 5 rotates. The bearing means 9 provided on the receiving portion 7d of the cap member 7 has a function of drastically reducing the frictional resistance between the rotating shaft 6 and the cap member 7 to make the rotation of the rotary handle 4 light.

Although the present invention has been described with reference to the embodiment, it is needless to say that the present invention is not limited to the above embodiment. For example, in the embodiment, the shaft head 6b of the rotating shaft 6 and the main shaft portion 6a have a stepped structure with different diameters, but as shown in FIGS. 3 and 4, the shaft head 6b of the rotating shaft 6 is solid. The main shaft 6a may be formed as a round bar and the flat portion 6d may be provided to form a non-circular cross section. In this case, the shaft hole 4a of the rotary handle 4 has a non-circular shape matching the main shaft portion 6a, and the receiving cylinder 4c of the rotary handle 4 becomes unnecessary as shown in FIG. It has a shape (see the rotary handle 102 in FIG. 6). Therefore, the structure of the rotating shaft 6 and the cap member 7 may be slightly changed, and the cost can be reduced by using a conventional operation handle mold.

Further, the bearing means 9 provided between the receiving portion 7d of the cap member 7 and the shaft head 6b of the rotary shaft 6 is not limited to the configuration provided on the receiving portion 7d side as in the embodiment. As shown in the above, the end face of the shaft head 6b of the rotating shaft 6 is formed into a mountain shape that bulges toward the center like a cone or a hemisphere, or a structure in which a short axis such as a cylinder or a hemisphere protrudes. You may. Furthermore, the operating handle 2 is not limited to one that is directly connected to the spring force adjusting pulley 5 to adjust the hitting force of the shooting ball. For example, the operating angle of the rotating shaft 6 is converted into an electric signal to fire the hitting ball firing device. It can also be used to increase or decrease the motor torque.

[0018]

According to the operating handle of the present invention, the shaft head of the rotating shaft is sandwiched between the rotating handle and the cap member to restrict the movement in the axial direction.
No ring is required, and if the cap member is attached to the base member, the rotating shaft can be fixed by itself. Therefore, parts cost reduction, workability and productivity dramatically improved,
There is an excellent effect.
