Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electric pachinko machine equipped with operating mechanisms for starting and stopping a triggering device and adjusting the triggering force.

Conventionally, in this type of electric pachinko machine, there are machines in which the ball is fired simultaneously with the rotational operation of the rotating grip, and machines in which the start and stop of the game and the adjustment of the force of the game are operated completely independently. In the former, the ball is fired even when the ball is weak, regardless of the gamer's will, forcing the game to fire a weaker ball, which is a waste of time, and in the latter, the gamer always has two parts. There was a flaw that the operation was complicated because it was necessary to operate and hold it.

The purpose of this invention is to solve the above-mentioned conventional problems by preventing the gamer from starting the bullet against his or her will at the beginning of the rotation of the rotating grip, and by automatically Once the bullet is started, the bullet can be continued by holding the rotary grip, and even when the rotary grip is not rotated beyond a certain level, the game can start and stop the bullet based on the player's will.

By being able to engage with the pair of locking protrusions 20 of 14, the rotation range of this rotating grip 28 is restricted to 150 degrees or less.

Reference numeral 31 denotes a spring wound around the operation shaft 8 so as to be interposed between the boss portion 16 of the fixed grip portion 14 and the boss portion 29 of the rotary grip portion 28. The shaft 8 is urged forward in the axial direction. Reference numeral 32 denotes a cam surface formed on the entire inner circumference of the rotating gripping portion 28, except for the non-pressing portion 32a whose upper portion has a larger diameter by 30 degrees as shown in FIG. A pressing portion 32b having a small diameter is formed, and the engaging pin 26 of the pressing member 22 is engaged with the pressing portion 32b.

Reference numeral 33 denotes a normally open type micro switch for driving the motor 2 which is attached to the fixed grip part 14, and its operating part 33a is brought into contact with the pressing part 27 of the pressing member 22. operating part 3
When 3a is pressed, the motor 2 is driven, and when the pressure is released, the motor 2 is stopped. The lead wire of the micro switch 33 is extended to the rear of the machine through an insertion hole (not shown) that communicates from the bottom surface 15a of the fixed grip part 14 to the support plate 17, and is connected to the motor drive circuit.

Next, the explosive attack will be explained. FIG. 4 shows the pre-operation stopped state of the elastic device, in which the engaging pin 26 of the pressing member 22 is connected to the non-pressing portion 3 of the cam surface 32 of the rotating gripping portion 28.
2a, the pressing member 22 is rotated outward about the support shaft 23 by the urging force of the actuating part 33a of the micro switch 33, and the micro switch 33 is opened as shown in FIG. show. At this time, the engaging protrusion 30 of the rotating gripping part 28 is connected to the locking protrusion 2 of the fixed gripping part 14, as shown in FIG.
It is at the zero point position engaged with 0.

When the rotary grip portion 28 is rotated in the direction of the arrow R from this state, if the rotation angle θ of the rotary grip portion 28 shown in FIG.
Since the microswitch 33 only moves relatively within the non-pressing portion 32a of the cam surface 32, the pressing member 22 continues to be rotated outward and the micro switch 33 maintains the open state. Therefore, the motor 2 is still not rotated.

When the rotation angle θ exceeds 30 degrees, the engagement pin 26 of the pressing member 22 is moved toward the cam surface 32 as shown in FIG.
The pressing member 22 is automatically rotated inward about the support shaft 23, and the pressing member 27 is pressed by the operating part 33 of the micro switch 33.
By pressing a, the micro switch 33 is closed. Therefore, the motor 2 is rotated.

When the rotating grip part 28 is held so that the rotation angle θ exceeds 30 degrees, the plate cam 1 is rotated in the direction of the arrow P by the rotation of the motor 2, and each rotation of the plate cam 1 causes the plate cam 1 to rotate. 4a is pushed down to give the actuating arm 4 a swinging movement in the direction of the arrow Q about the rotation axis 5, so that the batting rod 6 fixed to the rotation axis 5 is also affected by the tension of the spring 9. It is resisted and rotated in the same direction. When the plate cam 1 separates from the roller, the batting rod 6 instantly returns to its original position due to the tension of the spring 9, and the batting mallet 6
The ball at the tip of the ball hitting rail 12 is hit by a.

This operation is continuously repeated as long as the rotation angle θ of the rotation grip portion 28 is maintained at 30 degrees or more, and the ball is automatically and continuously hit. The elastic force at this time is adjusted by adjusting the amount of rotation of the rotating grip portion 28 and changing the elastic force applied to the spring 9.

Note that if the rotating grip part 28 is released, the spring 9
Due to the elastic force, the engaging protrusion 30 of the rotating gripping part 28 automatically returns to the zero point where it engages with the locking protrusion 20 of the fixed gripping part 14.

When the rotation angle θ of the rotation grip part 28 is 30 degrees or less, the player presses the pressing member 22 arbitrarily to close the micro switch 33 intermittently and hit the weak ball either singly or continuously. be able to.

In addition, when the ball hitting rod 6 is activated, the tension fluctuation of the spring 31, which expands and contracts according to the movement, is transmitted to the operating shaft 8. Therefore, if there is play in the operating shaft 8 supported by the machine base, the operation Vibration is transmitted to the game player who grips the rotational grip part 28 of the shaft 8, causing discomfort and making it difficult to hold the rotation grip part 28 stably. By biasing the operating shaft 8, the shaking of the operating shaft 8 is eliminated, and the vibrations received by the gamer from the rotary grip portion 28 can be significantly reduced, eliminating discomfort and at the same time facilitating stable holding. .

The relationship between the rotational grip portion 28 for adjusting the spring force and the pressing member 22 for starting and stopping the spring in this embodiment described above is as follows. First, when the amount of rotation of the rotating grip part 28 is less than 30 degrees from the zero point, the micro switch 33 is in an open state by the pressing member 22 and the rebound is stopped. When the micro switch 33 is pressed, the micro switch 33 is closed, so that single or continuous firing can be performed as desired. Next, the rotating grip part 28
When the amount of rotation is 30 degrees or more, the micro switch 3 is
3 is closed and becomes a continuous firing state.

Therefore, if the game player does not press the pressing member 22 when rotating the rotating grip portion 28 to adjust the spring force, the motor 2 will not be activated when the rotation amount is less than 30 degrees. This prevents weaker pitches from being fired. However, even if the amount of rotational operation is less than 30 degrees, if the game player presses the pressing member 22, the motor 2 will be activated, so that the weak ball can be fired single or continuously as desired. When the amount of rotational operation is 30 degrees or more, the pressing member 22 is automatically pressed and the motor 2 is activated, so that continuous firing can be continued. As illustrated in FIG. 9, a normally closed micro switch 38 is connected in series to the micro switch 33 of the fixed grip part 14, and the switch 38
If it is installed in a position where the player can open and close it at will, the switch 38 can be used to fire a single shot at will even when the rotation amount of the rotating grip 28 is 30 degrees or more.

As detailed above, the electric pachinko machine according to the present invention is provided with an operating member 13 operated by a game player on the front of the machine, and the operating member is connected to the power source for the starting motor 2 of the triggering device. Switch 3 to turn on
A pressing member 22 for pressing 3 to close the circuit is provided in a pressable and fixed position, an engaging member 26 is formed protrudingly on the pressing member 22, and the operating member 13 is provided with an elastic member 26 of an elastic device. A rotary gripping portion 28 for adjusting the force generation is rotatably provided, and a cam surface 32 that slides into contact with the engaging member 26 is provided on this rotary gripping portion 28, and the cam surface 32 further includes:
When the rotating grip portion 28 is rotated by more than a certain angle from the pre-operation state where it is not rotated, the engaging member 26
a pressing part 32 that presses the pressing member 22 by pressing the button to activate the elastic device;
(b) When the rotary grip portion 28 rotates by less than the certain angle, the engaging member 26 is not pressed, thereby opening the switch 33 of the triggering device and preventing the triggering device from being activated. Since the non-pressing portion 32a is provided, when the game player rotates the rotary grip portion 28 to adjust the elastic force, if the pressing member 22 is not pressed, the amount of rotation operation will be reduced. The projectile device is not activated when the ball is below a certain angle, preventing the projectile firing of a ball with weak momentum, and even when the amount of rotational operation of the rotating grip part 28 is below a certain angle, the gamer can When the user presses the pressing member 22, the firing device is activated, allowing the ball to be shot with low force.Furthermore, when the amount of rotational operation of the rotating grip portion 28 exceeds a certain angle, the pressing member 22 is activated. is automatically pressed and the firing device is driven, so continuous firing can be continued. Therefore, the present invention can prevent the triggering device against the gamer's will at the initial stage of rotation of the rotary gripping portion 28, thereby preventing unnecessary rebounding of weaker balls for the gamer. If only the rotating grip portion 28 is rotated over a certain angle and held, firing can be automatically started and continued.Furthermore, even when the rotating grip portion 28 is not rotated over a certain angle, it can be held according to the player's will. It has the effect of allowing weaker balls to be fired based on the ball.
