Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a so-called bullet device in which the elastic force of a bullet hammer is investigated by operating a noddle of 44 degrees.

Recently, regarding the bullet ball, which is the central part of a pachinko machine,
Its compactness makes the work with OFFI S basic.

ll1l - Noise suppression, ease of design changes, etc.
Many 1 shots are being developed based on the point, but most of them are aimed at reducing manufacturers' costs and labor saving, or improving hall equipment and A, and are aimed at improving players' 4T-considerations.
There are few non-woods. In other words, the d1 type pachinko machine requires less fingertips and bowls than the 1 manual type pachinko machine.
However, since the muscles are continuously used to operate the four types of handles, when playing for a long time (5 hours for a normal person), the acceleration decreases. This will lead to increased fatigue.

Therefore, when we analyzed and considered the cause of this fatigue, we found that the spring force applied to the ball mallet includes the single spring force required to round the ball to at least the first position on the rail, and in addition to this. There is an Am elastic force that is added to cause the ball to fall to a desired position on the game board, but the conventional ball device uses, for example, a single tension coil spring between the all adjustment handle and the ball mallet.・With a configuration that applies both the basic elastic force and the lid elastic force to the ball mallet by applying 4 tension to the tension coil spring by 1g1- of the 9/4 value handle, the player!
It must not be necessary to continuously apply rotational force to the t11 bottle, resisting not only the normal force but also the basic force.

In short, the basic elastic force is constant depending on each type, and even though it is not originally a type of force that applies to the player's fingertips, it is caused by the player Wc*, so the above-mentioned acceleration This resulted in a significant increase in fatigue.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to allow the player to play a bullet ball by burdening only the fA* rebound force, and to play the game with I for a long time. To provide a straight-from-the-sale pachinko machine with less fatigue.

An embodiment of the present invention will be described below with reference to the drawings. 1 is a support plate, for example, made of plastic, which is attached to the back side of the pedestal 2 in a 111-pachinko machine;
A shaft 5 of a ball mallet 4 is rotatably supported on this via a bearing st. 6 is located on the turning locus of an impeller 8 driven by a deceleration motor (only the output kerf is shown) attached to the support plate 1. 9 is a collar fixed to the support plate 1 below the ball mallet 4 with two screws 10, and its mounting tongue piece 11 a p 11 a
The rubber cushioning material 12 is fixed by caulking to the holder part 111) of the holder 11 made of gold, which is provided with a long hole 13 through which the mounting tongue piece 11 & e 11 aK screw 10 passes. 15 are drilled. And the supporting pre τ
Five guide convex portions 14 are protrudingly provided on the stopper 1 to abut on the right and left sides 94 of the mounting tongue piece 11'y11a of the holder 11, allowing the stopper 9 to be moved in the vertical direction. 15 is a support plate) IK is rotatably supported on a shaft 16 that is erected.
It is a nine-turning body, and the upper part of this body and the middle part of the ball mallet 4 are connected and connected to each other by a link 17. Reference numeral 18 denotes a tension coil spring as a first spring whose one end is hung on the lower end of the rotating body 15, and the thread 19 connected to the other end of this spring is in the middle s2.
Nine pulleys 2 are rotatably provided on the support plate 1.
It is multiplied by 0.21tC. Reference numeral 22 is a nine-al JIE handle 250 times-1 provided on the stand 112, and a substantially fan-shaped winding body 24 is fixed to the end of the hand h1), and the end of the thread 19 is attached to a part of the outer periphery of the winding body 24. connected. 25 was fixed to the lower part of the support plate 1 with screws. n**m,
A plurality of circular fitting holes 2 are formed around the shaft hole 26& in the center of the holder 26 on a concentric circle centered on the shaft hole 26&.
6b are bored at equal intervals. 27 is provided with an integrated VC collar 27b having a thread hook 127a at one end 11.
4, is this the compression coil 2B? Through the shaft hole 26
A Kumiib can be inserted into the capital, #Kantoyo shaft 27
In addition, an adjustment plate 29 is fixed with screws 50 and washers 51. And - mm of the straightening plate 29 is a circular base metal convex portion 2 corresponding to the fitting hole 261)? L is the fitting hole 25
11, and the compression coil spring 280 is fitted into the fitting convex portion 29& by the elastic force of the spring 280. S2 is Fs2 whose one end is hung on the lower end of the rotating body 15
A tension coil spring is used as a spring, and the thread 52 connected to the other end of the tension coil spring is the part 27 of the tension coil spring.
It is connected to a.

Next, the operation of this embodiment configured as above will be explained. When the AIR shaft 27 is pushed in against the compression coil spring 28 and excited, the fitting convex 1fls 29 of the adjustment plate 29
a is removed from the fitting hole 261) of the holder 26, and the cough adjustment shaft 27 is attached to the holder 26 and becomes rotatable. In this state, when the Am pongee 27 is turned in one direction, the thread 55 is The thread hook is wound around the portion 27a, and the tension of the tension coil spring 52 is 4.
) Ja, and conversely, when the Ii1'4 sleeve 27 is turned to the low position 27, the thread 35 is pulled out from the thread hooking portion 27a, and the tension of the tension coil spring 32 is reduced. By the way, the repulsion force required for the ball to be ejected from at least the upper layer of the rail is as follows: It's strangely different. Therefore, by rotating the A-wear 411127 as described above, the thread 550 winding tt by the thread hooking part 27 & is changed, so that the tension of the tension coil spring 52 becomes the desired basic elastic force according to each isogashi. After setting the foot + il #A2
When the pushing force on 7 is removed, the straightening shaft 27 moves outward due to the elastic return force of the compression coil spring 28, and 6i4
The fitting protrusion 29& of the adjustment plate 29 is inserted into the fitting hole 26m of the holder 26.
)KIE match. As a result, a certain basic elastic force is applied to the ball mallet 4. On the other hand, when the rotating shaft 22 is rotated in the direction of arrow A using the aims handle 23, the winding body 24 is rotated.
The thread 19 is wound up to increase the tension of the tension coil spring 18.

When the rotary shaft 22 rotates 1n in the direction of arrow A, the deceleration motor is energized and its output s7 is rotated at low speed in the direction of arrow B. The mallet 4 is rotated in the direction of the arrow C, and the rotating body 15 is rotated in the direction of the arrow C via the link 17 in conjunction with the mallet 4. Since the rotating body 15 rotates in the direction of arrow C against the tension coil springs 18 and 52, when the impeller 8 comes out of contact with the operating shaft 6, the rotating body 15 moves against the tension coil springs 18 and 52. and 32, and due to the force of the nine bullets, it makes a return rotation of 41L in the opposite direction of arrow C, and at the same time, via the link 17, the bullet ram suddenly returns and rotates 4% in the same direction of arrow C, This causes the ball supplied to the m-plane to bounce. When the repulsion of the rotation lA44i122 is small, the tension acting on the tension coil spring 18 is small, and therefore the basic elastic force of the tension coil spring 32 acts exclusively on the ball mallet 4, causing the ball to bounce. In this case, the ball will be launched to the left end of the game board surface. On the other hand, arrow A on rotation axis 22
As the rotational force in the direction increases, the tension of the tension coil spring 18 gradually increases, and in addition to the elastic force of the tension coil spring 18, the elastic force of the tension coil spring 18 is added to the bullet @4. As a result, the batted ball will gradually fall to the right on the game surface. The tension applied to the tension coil spring 18 by the rotation of the sleeve 22 corresponds to the elastic force Am.

Therefore, the basic elastic force of the tension coil spring 1252 acts on the ball mallet 4, and since the ball can be ejected from the upper end of the rail with only this basic elastic force, the coil spring 18
It is only necessary to apply a tension corresponding to the A-shaped bullet firing force necessary to make the ball released from 4 further fly to the desired position on the 71st plane on the rail. Only the reaction force from the retired coil spring 18, which corresponds to the adjusted spring force, acts on the fingertips and arms of the player who biases the ball towards the top of the rail. The AWt spring force needed to change the AWt to the left and right of the top of the board is very small, and the conventional MoO, which operates the l1ll differential handle against both the basic spring force and the adjusted spring force, is very small. In comparison, the reaction force applied to the player's fingertips is relatively small. In the above configuration, the orientation direction of the elongated hole 1.5 provided in the holder 11 of the stopper 9 is set in the vertical direction, and the stopper The direction of the load 1o applied from the mallet 4 to the comb material 12 of 9 is set at an angle of about 45° with respect to the direction of the elongated hole 15, and the holder 11 is placed on the support plate 2 so that the direction of the load 10 is set to the direction of the elongated hole 13. Since the guide protrusion 814 is provided to guide the material in the direction, the stopper 9 can be prevented from moving due to the load applied to the cotton wool material 12 by the ball mallet 4.
% to prevent n1 stopper 9 from place 1 installation position to 6J6? It can be A4.

゛Furthermore, the brass structure 25 may be provided as necessary, and its configuration t can be changed one by one.

Further, the rotary body 15 may be provided as necessary, and may be hung directly on the tension coil springs 18 and 52, and the first and second springs may be attached to the tension coil springs 18 and 52 directly. It may also be configured by a spring.

As is clear from the embodiments described above, in the present invention, when the player only applies a force of 114 mm using the adjustment handle, the ball is hit by the ball mallet, and the player's fingertips and arms are hit. Since the reaction force involved is very small, the bullets in Pachinko I, which can be played for a long time without causing fatigue! AIt can be done with tigers.
