On the other hand, in the elastic force adjusting mechanism 17, the base 8
The second pulley 2 connected to the front end of the rotation support shaft 11 by a winding operation portion 21 in a case 18 screwed to the
6 by operating the coil-shaped adjusting spring 27 to expand and contract.
Adjust the resilience of the. The case 18 is of a two-part type and has an engaging portion 19 for engaging with the engaging portion 4 of the fixture 2 on the front surface, and an insertion tube 20 for the support shaft 7 of the operating tool 6 is integrally formed.

Reference numeral 33 denotes a touch sensing panel, and 34 denotes an operation switch.
9 is set. Touch sensing panel 33 has sensing surface 3
At 3a, a signal is issued when the player's hand or finger touches. On the other hand, the operation switch 34 is a normally closed contact type for switching the motor 30, and is operated by an operation piece 35. Operation piece 3
The operation switch 5 is restrained before the operation tool 6 rotates.
4 is closed and opened at the time of rotation, and the operation lever 35a is opened and closed by pushing and releasing the operation piece 35 with a fingertip to switch the operation switch 34. The operation piece 35
Is linked to the operating tool 6 using the cam 35a and the pin 6a, and changes to the open position by the urging force of the actuator lever 34a. The drive control board C is constructed by incorporating a circuit board 43 in a case 40, and signals from the respective devices are transmitted to the circuit board via unillustrated lead wires, relay terminals 37, relay connectors 38, and lead wires 39. 43. The case 40 is removably assembled with a cover box 42 that matches the receiving box 41. or,
Reference numeral 49 denotes a wiring board for connecting the lead wires 50.

Next, FIGS. 3 to 8 show mounting parts near the cam 32. FIG. The motor 30 is installed on a support plate 29 fixed to the legs 12 of the base 8 with screws. In FIG. 3, a protrusion 50 for preventing idling is projected from the elastic motor shaft 31 having hardness, while a hole 51 that can be fitted and fixed to the protrusion 50 is formed in the coupling hole 32a of the cam. The motor shaft 31 is inserted and fixed in the coupling hole 32a, and rotates the cam 32.
FIG. 4 shows that a screw 53 is formed at the end of the elastic motor shaft 31 having hardness, while a screw 54 is screwed into the coupling hole 32a of the cam. And are screwed together. Thus, the motor shaft 31
And the cam 32 are connected via an elastic body,
The vibration generated during the contact between the cam 32 and the roller portion 14a is:
It is absorbed by the elastic motor shaft 31. As a result, the vibration of the hitting rod 13 is reduced, and the vibration transmitted to the grip ring 5 can be reduced. In the above example, the motor shaft 31
Is an elastic body, but the entire cam 32 or the coupling hole 32a
The same effect can be obtained even if the portion is made of a hard elastic body or both are made of an elastic body. In addition, the elastic body having hardness refers to a hardness that can function as a part and has an elastic function.

FIG. 5 shows a conventional motor in which the motor shaft 31 and the cam 32 are connected via screws 62. A screw screw hole 31a for fixing the cam 32 is formed in the motor shaft 31 via a screw 62. Reference numeral 60 denotes a cam coupling hole 3
It is a cylindrical elastic body that can be inserted between the motor shaft 2a and the motor shaft 31, and has a screw hole 60a formed in a side portion. or,
The cam 32 has a coupling hole 32a in which the elastic body 60 is fitted.
A screw hole 32b is formed in the side portion. And
The motor shaft 31 is provided with an elastic body 6 fitted in the coupling hole 32a.
As shown in FIG. 6 showing a cross section, the screw 62 is screwed from the screw hole 32b and screwed and fixed.
The use of the contact plate 64 can prevent separation due to vibration. FIG. 7 shows a case where the screw 62 is fixed via a cylindrical elastic ring 63 and a contact plate 64 in order to further reduce the vibration transmitted to the grip ring 5. As shown in the sectional view, the screw 62
Is a structure that does not contact the cam 32. In addition, in addition to the above-described configuration, the entire roller portion 14a or the surface thereof may be formed of an elastic body, the cam portion 32c in contact with the roller portion 14a may be formed of an elastic body, and both of the cam portions 32c may be formed of an elastic body. Thus, vibration transmitted to the grip ring 5 can be reduced.

When the player rotates the grip ring 5,
The sensing panel 3 senses that the player's finger or the like has touched, and the operation switch 34 is turned on to start the motor 30. In addition, the resilience of the hitting rod 13 is adjusted via the resilience adjusting mechanism 17 by the amount of rotation of the grip ring 5. The cam 32 which is rotated by the motor 30 is driven by the roller portion 14a of the striking rod 13 for a predetermined time.
The step of detaching after maintaining the contact state with is repeated. That is, the hitting rod 13 is reciprocated at regular intervals, and the hitting rod 1 is moved.
With the resilience of 3, the game balls are sequentially fired on the game surface. At this time, when the cam 32 and the roller portion 14a are in contact with each other, vibration occurs due to rubbing. In FIG. 3 and FIG. 4, most of the vibration is caused by the motor shaft 31, the cam 32, or the cam 32 made of an elastic body. Is absorbed by both elastic members. FIG.
In the above, the elastic body 60 fitted into the motor shaft 31
Is absorbed by. Therefore, the player holding the grip ring 5 only feels the vibration immediately after the game balls are sequentially fired, and plays the game without worrying about the vibration caused by the so-called friction between the cam 32 and the roller 14a. It is possible. Also, when the motor shaft 31 and the cam 32 are fixed with the screw 62 using a cylindrical elastic ring 63 as shown in FIGS. 7 and 8, the screw 62 does not contact the cam 32. The vibration generated in the cam 32 and the roller 14a is further absorbed, and the vibration generated in the grip ring 5 can be reduced, so that a comfortable game can be played. The elastic ring 63 may be formed in the same shape as that of the backing plate. or,
As described above, the vibration generated in a state of contact with the roller portion 14a of the hitting rod 13 is such that the roller portion 14a is formed of an elastic material, or the cam portion 32c that contacts the rotor is formed of an elastic material.
Furthermore, even if both are made of an elastic body, the vibration can be absorbed by any of the elastic bodies, and the vibration transmitted to the grip ring 5 can be reduced (see FIG. 7). In addition, hitting rod 1
The same effect can be obtained even if one of the roller portion 14a and the cam portion 32c is made of an elastic material and the motor shaft 31 and the cam 32 are connected by an elastic material. Further, it goes without saying that the present invention can be applied to a game machine having a hitting rod such as a slot machine in addition to a pachinko machine.

Then , since the elastic body is attached so as to be able to absorb the vibration generated in the cam and the hitting rod , the vibration is absorbed by the elastic body, and the vibration transmitted to the grip ring can be reduced. Can play a game comfortably.
Further, in the electric firing device according to the second aspect, a screw is applied via a backing plate.
Screw into the screw hole to prevent separation due to vibration.
Is being planned.
