Description

[Detailed description of the invention] (Industrial application field) The present invention relates to improvements in electric pachinko machines.

(Prior Art) Various grip devices for operating batted balls have been proposed for electric pachinko machines. As shown in Publication No. 84182, a support member is provided on the front frame of a game board so as to face forward of the front frame, and a grip is placed on the upper surface of the support member so that its rotation axis is in the vertical direction. There are some things that I support.

(Problem to be Solved by the Invention) However, with the above configuration, in order to rotate the grip, the wrist must be rotated around the arm, and such wrist movement is This is more difficult than bending the wrist in a direction in which the back of the hand and the palm of the hand approach the arm, making it difficult to rotate the grip quickly and accurately. As a result, the hitting force of the pachinko balls cannot be adjusted properly, making it impossible to accurately hit the pachinko balls to a predetermined position on the game board surface, which may reduce the player's desire to play.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to prevent fatigue of the wrist that grips the grip, and to quickly and accurately adjust the hitting force of the pachinko ball.

(Means for Solving the Problems) In order to achieve the above object, in the present invention, a casing 2 is provided protruding from the front frame 1a, and the axis of the casing 2 is arranged in the horizontal direction, and the game board 1
A grip 16 having a rotation axis m that is the same as the axis of the support member 8 is provided adjacent to the support member 8, and a biasing member for biasing the grip 16 to rotate in one direction is provided. The support member 8 and the grip 16 are provided with a force means 22, and the adjacent ends of the support member 8 and the grip 16 are formed into a substantially circular cross-sectional shape, and the outer diameters of the adjacent ends are made similar to each other.

(Function) With the above-described configuration, even when grip 16 is held by hand, it is possible to keep the eye straight from the arm to the back of the hand, and grip 16 can be held without bending the wrist.

Further, the grip 16 can be rotated by moving the wrist in a direction in which the back of the hand and the palm of the hand approach the arm, and the grip 16 can be rotated quickly and accurately.

Furthermore, in the grasping operation, the urging means 22 and 36 are rotated by placing the palm of the hand and part of the fingers in the circumferential direction of the support member 8 along the boundary between one end of the support member 8 and the grip 16. The support member 8 and the grip 16 are gripped simultaneously and easily against the dynamic bias.

This prevents the entire arm or hand from taking an unreasonable posture, and when the desired ball hitting force is obtained, the entire hand including the palm and fingertips can wrap around the support member 8 and the grip 16.

The weight of the entire arm is applied mainly to the grip 16 and the support member 8 through the palm, and is hardly applied to the fingertip side. Therefore, when grasping the grip 16, the burden on the fingertips required to support the weight of the entire arm is extremely reduced.

Furthermore, in order to hold the grip 16 against the rotational bias of the biasing means 22 and 36, a portion of the weight of the arm is applied to the support member 8 and the grip 16.
The force for grasping the support member 8 on the fingertip side is replaced by part of the weight of the arm.

Therefore, it is no longer necessary to use the support member 8 as a support surface to forcefully press the palm and fingers of the hand against the grip 16 or to tightly grasp the grip 16.
This reduces the burden of grasping with the fingertips and prevents fatigue.

Furthermore, when rotating the grip 16,
The palm and fingertips are wrapped along the sides of the grip 16, and the entire hand is rotated in the direction of the fingertips being gripped around a rotational axis m along the palm. At this time, you can grasp the grip 16 without having to re-grasp it or put pressure on your wrist or arm.
is rotated continuously.

(Effects of the Invention) Therefore, according to the present invention, the grip 16 can be grasped without bending the wrist, thereby preventing wrist fatigue. Therefore, in addition to being able to maintain the desire to play, it is also possible to hold the grip 16 at a predetermined rotational position and repeatedly strike the pachinko ball at a predetermined position on the first surface of the game board, thereby increasing the desire to play. can be improved.

Further, since the grip 16 can be rotated quickly and accurately, the pachinko ball hitting force can be adjusted quickly and accurately.

During the grasping operation, the support member 8 and the grip 16 are simultaneously and easily grasped against the rotational bias of the biasing means 22 and 36, and the weight of the entire arm is transferred mainly through the palm of the hand to the grip 16 and the support member. Since it is added to the member 8, the above-mentioned grasping burden on the fingertip side is reduced.

For this reason, when grasping the grip 16, it is easy to reliably hold the grip 16 at the desired position, that is, with the desired batting force, which prevents fatigue of the entire arm or hand caused by continuous pachinko play. To prevent a decrease in the desire to play due to fatigue.

On the other hand, when the grip 16 is rotated, the grip 16 is continuously rotated, so that the desired ball hitting force can be adjusted smoothly, easily and quickly, and any finger (for example, the thumb) that is gripping the ball can be attached to the support member. Simply place your finger on the boundary between one end of the grip 8 and the grip 16, and shift your other finger toward your fingertip using this finger as a fulcrum.
The grip 16 can be easily grasped again.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

A rotary shaft 5 is rotatably supported by the bearings 3 and 4. One end side (upper side in FIG. 5) of the rotating shaft 5 passes through the front frame 1a and extends to the rear side of the front frame 1a, and a winding cam 6 is attached to the rotating shaft 5. It is attached on the rear side of 1a. The other end of the rotating shaft 5 extends toward the tip of the casing 2, and a bevel gear 7 is mounted on the other end of the rotating shaft 5.

A cylindrical metal support member 8 is fixed to one side of the casing 2 . A flange portion 9 is provided on the outer periphery of one end of the support member 8, and the support member 8 is fixed to one side surface of the casing 2 via the flange portion 9. A portion of the flange portion 9 extends toward the front frame 1a along the side surface of the casing 2 to ensure mounting strength, and the support member 8 is located at the tip of the casing 2. An opening 10 is formed in one side of the casing 2 facing the opening on the one end side of the support member 8, and bearings 11 and 12 are attached to the periphery of the opening of the casing 2 and the inner periphery of the other end of the support member 8, respectively. ing. Bearing 1
A rotating shaft 13 is rotatably supported by 1 and 12, and the rotating shaft 13 extends in the horizontal direction and is connected to the game board 1.
is facing. One end side of the rotating shaft 13 faces into the casing 2, and a bevel gear 1 is mounted on the one end side.
4 is installed. This bevel gear 14 and the bevel gear 7 mesh with each other, and when one rotating shaft 13 (or 5) is rotated about the axis of the rotating shaft 13 (or 5), the other rotating shaft 5
(or 13) rotates around its axis.
A protrusion 15 is formed on the outer periphery of the support member 8 in the circumferential direction, and the protrusion 15 is located slightly closer to the other end of the support member 8 than the center of the support member 8 in the axial direction. . The outer diameter of the support member 8 between the protrusion 15 and the flange portion 9 is such that it can be appropriately grasped with the thumb and index finger.

A bottomed cylindrical grip 16 is fitted to the outer periphery of the other end of the support member 8 so as to be relatively rotatable until its open end is regulated by the protrusion 15.
The center of the inner bottom of 6 is fixed to the other end of the rotating shaft 13. Therefore, by rotating the grip 16 around its axis m, the rotating shaft 5
will rotate. The outer periphery of the grip 16 has a plurality of grooves 1 extending in the axial direction of the grip.
7 are formed at equal intervals in the circumferential direction of the clip 16. As is clear from FIG. 3, the outer diameter of the grip 16 at the adjacent end of the support member 8 and the grip 16 is approximated to the diameter of the other end of the grip 16.

A fixing member 18 is attached to the rear surface of the front frame 1a, and a support shaft 19 is rotatably attached to the fixing member 18. The base of a ball mallet 20 is fixed to the support shaft 19, and the tip of the ball mallet 20 faces a firing section at the lower end of a firing rail 21.

A spring force adjustment mechanism 22 is fixed to the fixed member 18 . This spring force adjustment mechanism 22 includes a ball hammer 2.
The spring force adjustment mechanism 22 is connected to the winding cam 6 through a wire 24. This spring force adjustment mechanism 22 has a function of increasing the spring force within the spring force adjustment mechanism 22 when the wire 24 is wound around the winding cam 6 in accordance with the rotation of the grip 16. In order to swing the batting mallet 20 counterclockwise in FIG. 2 about the center point 19, it is necessary to increase the force. This spring force adjustment mechanism 2
2 has already been disclosed in Japanese Patent Application No. 53-72266 and is well known, so a detailed explanation thereof will be omitted.

A pin 25 is provided protruding from the ball hammer 20. A cam 26 acts on this pin 25, and by rotating in one direction, this cam 26 comes into contact with the pin 25 and moves the ball hammer 20 around the spindle 19 as shown in FIG. Swing a certain amount counterclockwise,
Thereafter, it has a function of releasing the contact relationship with the pin 25. A motor 27 is connected to the cam 26, and the motor 27 is fixed to the fixed member 18. This motor 27 is connected to a power source (not shown) via a starting switch (not shown), and is turned on as the starting switch winding cam 6 rotates. That is, when the grip 16 is at a stable resting position (the end of the rotation stroke on the game board 1 side), the winding cam 6 does not act on the starting switch, and the starting switch is turned off.
After the winding cam 6 is rotated slightly toward the player, the winding cam 6 acts on the starting switch, and the starting switch is turned on.

One end of an L-shaped stop lever 28 is rotatably supported on the inner wall of the casing 2, and the other end of the stop lever 28 projects from the front surface of the casing 2. A micro switch 29 faces the rotation area of the stop lever 28, and the micro switch 29 is fixed to the inner wall of the casing 2. This microswitch 29 is connected to the power supply circuit of the motor 27 in series with the starting switch. The microswitch 29 is normally closed, and when the microswitch 29 is actuated via the stop lever 28, it is opened. Therefore, even if the starting switch is turned on, the driving of the motor 27 can be stopped by turning on the micro switch 29 via the stop lever 28, and it is also possible to hit pachinko balls intermittently. Become.

Next, the operation of the above configuration will be explained.

First, when the grip 16 is not rotated in any way by the player, the spring force adjustment mechanism 22 causes the grip 16 to be at the end of the rotation stroke on the game board 1 side, and as a result, the winding cam 6 and the starting switch come into contact with each other. The startup switch is turned off because it is not used.

When playing a game, the player grasps the grip 16 with the palm of his hand (usually his right hand) in contact with the outer peripheral surface of the grip 16. After this,
When the grip 16 is rotated toward the player by an operation of the wrist, the starting switch is turned on and the motor 27 is energized, so that the batting mallet 20 continuously hits the pachinko balls. When rotating the grip 16, hold the palm and fingertips of the grip 16.
The entire hand is rotated around the rotation axis m along the palm of the hand toward the fingertips that are being grasped. Since the grip 16 is continuously rotated without putting any burden on the player, the desired ball hitting force can be adjusted smoothly, easily and quickly. Alternatively, while holding one finger (for example, the thumb) on the boundary between one end of the support member 8 and the grip 16 and pressing it, use this finger as a fulcrum and shift the other fingers toward the fingertips to release the grip 16. It can be easily re-understood. When the amount of rotation of the grip 16 is increased, the spring force adjustment mechanism 22 is pulled through the wire 24, and as a result, the spring force, that is, the striking force, applied to the ball hammer 20 by the spring force adjustment mechanism 22 increases. , the impact force is adjusted according to the amount of rotation of the grip 16.

Once the desired amount of rotation of the grip 16 has been determined, grip the outer periphery of the support member 8 with your thumb and index finger, while using your palm and other fingers to rotate the grip 16.
, and hold the grip 16 against the support member 8 so as not to rotate. At this time, by placing a finger along the boundary between one end of the support member 8 and the grip 16, the support member 8 and the grip 16 are simultaneously pressed against the rotational bias of the biasing means 22 and 36, and Since it can be easily grasped, the whole arm or hand will not be in an unreasonable posture, and when the desired ball hitting force is obtained, the whole hand of the palm and fingertips will be able to push the support member 8
and can wrap around the grip 16. Therefore, the weight of the entire arm is applied to the grip 16 and the support member 8 mainly through the palm of the hand, so that the gripping burden on the fingertip side is reduced.

In this way, when rotating the grip 16, since the rotation axis m of the grip 16 extends in the horizontal direction and faces the game board 1, the wrist should be moved in the direction where the back of the hand and the palm of the hand approach the arm. Because it is extremely easy to move the wrist in the direction in which the back of the hand and the palm of the hand approach the arm, it is possible to quickly determine the desired amount of rotation of the grip 16, as well as to move the wrist in the direction in which the back of the hand and the palm of the hand approach the arm. Able to accurately perform minute rotations. Therefore, the pachinko ball striking force can be adjusted quickly and accurately based on the rotating operation of the grip 16.

Furthermore, once the desired amount of rotation of the grip 16 is determined, it is sufficient to grip the outer periphery of the support member 8 with the thumb and index finger, and grasp the support member 8 and the grip 16 with the palm of the hand and other fingers.
can be reliably held at a predetermined rotational position without being able to rotate.

FIGS. 6 to 9 show other embodiments, and the same components as those of the previous embodiment are designated by the same reference numerals, and the explanation thereof will be omitted.

In this embodiment, the rotation of the grip 16 is converted into an electrical signal, and based on the electrical signal, the solenoid 3 is
0 is activated, the solenoid 30 drives the plunger 31, and the plunger 31 hits the pachinko ball.

That is, a variable resistor 32 is provided inside the tip of the casing 2, and the variable resistor 32 is fixed to the inner wall of the casing 2. Variable resistor 3
The input shaft 32a of No. 2 passes through the opening 10 in the gaming state and extends into the support member 8.
and one end side of the rotating shaft 13 are connected via a joint 33.

Inside the support member 8, the support member 8 and a rotating shaft 13 are provided.
A touch sensor 34 is provided which is held by a
It is connected to the ON/OFF circuit 35. A return coil spring 36 is provided at the other end of the support member 8.
One end of the coil spring 3 is locked.
The other end of the grip 6 is locked to a grip 16, and the grip 16 is urged toward a stationary and stable position as the grip 16 rotates.

A solenoid 30 is provided in the firing portion of the firing rail 21, and a plunger 31 passes through the solenoid 30. One end of the plunger 31 is a springing part 31a, and the springing part 31a faces the striking area on the firing rail 21, while the other end of the plunger 31 and the solenoid 30 have both ends of the spring 37. Each is locked.
Here, 38 is a supply mechanism that supplies pachinko balls one ball at a time to the popping section.

The output side of a solenoid output control circuit 39 is connected to the solenoid 30, and the output side of a power ON/OFF switch circuit 35 and the output side of a solenoid output driver circuit 40 are connected to the input side of the solenoid output control circuit 39. It is connected. Solenoid output control circuit 39
includes the variable resistor 32 as a component, and the solenoid drive signal changes depending on the resistance of the variable resistor 32. Power ON・
The OFF switch circuit 35 includes the touch sensor 34 as a component, and the oscillation circuit 4 is connected to the input side of the solenoid output driver circuit 40.
1 output side is connected. The output side of a power supply circuit 42 is connected to the input side of the power ON/OFF switch circuit 35 and the input side of the oscillation circuit 41, and the output side of a rectifier circuit 43 is connected to the input side of the power supply circuit 42. A power source 44 is connected to the input side of this rectifier circuit 43.

Therefore, in the above configuration, when the metal support member 8 is touched, that is, when the support member 8 is grasped between the thumb and index finger, the touch sensor 34 is turned on, and a drive signal is sent to the solenoid 30 to control the solenoid output. It is output from the circuit 39. The plunger 31 is operated in accordance with this drive signal, and the plunger 31 and the spring 37
As a result, striking force is continuously applied to the pachinko ball.

When the grip 16 is rotated toward the player, the input shaft 32a of the variable resistor 32 is rotated, and the resistance of the variable resistor 32 is changed.
The resistance of the variable resistor 32 controls the drive signal from the solenoid output control circuit 39, and the plunger 31 causes the spring 37 to be largely displaced. Therefore, the repulsive energy of the spring 37 increases, and the impact force applied to the pachinko balls increases.

Although the touch sensor 34 was used in this embodiment,
Instead of the touch sensor 34, it may be turned on according to the rotation of the input shaft of the variable resistor 32. Also,
The grip 16 and rotating shaft 13 are made conductive,
By touching the grip 16, the touch sensor 34
may be turned on.
