Abstract

PURPOSE:To prevent the turn-back balls and to improve the working rate of the motor-driven game machine by providing a discharge strength detecting switch by detecting a manipulated variable of a handle, and operating a discharge hammer driving means only at the time when the discharge strength is within a prescribed range. CONSTITUTION:As a handle 2 is rotated, a discharge strength setting member 4 rotates in the counterclockwise rotating direction, and in connection therewith, a discharge hammer 6 also falls down in the left direction. When the discharge hammer 6 falls down, take-back of the discharge hammer 6 becomes large by its portion, and the discharge strength increases. However, while the discharge strength is low, a reed switch 26 is still tuned off, and the discharge operation is not operated, as well. When the handle 2 is rotated until the discharge strength reaches the extent that a hit ball reaches a same boards a magnet 27 approaches the reed switch 26, and the reed switch 26 is tuned on. In such a state, a solenoid driving circuit 23 operates, and the discharge operation is executed.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application This invention relates to a ball launcher for an electric game machine such as a pachinko machine.

(B) Prior Art Conventional hit ball launching devices for electric game machines include, for example, Japanese Utility Model Application Publication No. 59-167572, Japanese Utility Model Application Publication No. 60-1538.
The one described in Publication No. 2 is known. These ball launchers are equipped with a motor, a driving spring, a firing mallet, a handle, etc. As the motor rotates, a cam attached to the motor rotation shaft comes into contact with the firing mallet, and the firing mallet responds to the elastic force of the driving spring. It resists this and is moved to the opposite side of the launch. Eventually, the cam is disengaged from the firing mallet, and the firing mallet returns to its original state due to the elastic force of the drive spring, at which time the ball is struck and fired. The strength of the ball hitting force is determined by the elastic force of the drive spring, and can be set in conjunction with the rotation angle of the handle.

On the other hand, regulations require that the motor be turned on and off using a touch switch. That is,
When a human body touches the touch detection part of the handle, the motor is turned on and the ball is hit.

(c) Problems to be Solved by the Invention The problems of the hit ball launcher of the conventional electric game machine described above are explained in the fourth section.
This will be explained with reference to the drawings. FIG. 4 shows a front view of the -C pachinko machine 31.

When the handle 32 is touched and rotated in the clockwise direction of the paper in FIG. 4, the firing intensity increases in accordance with the rotation angle. However, the 320 rotation angle of the handle is small.
While the firing strength is weak, the pachinko balls 36 lose kinetic energy within the ball hitting path 33 and do not reach the game board 34. The pachinko balls 36 that have lost their kinetic energy turn around inside the ball hitting path 34 and return to the prize ball tray 35. Pachinko machines are expensive, and such folded balls reduce the operating rate of the pachinko machine and pose a major problem for pachinko parlor management.

This invention has been made in view of the above, and aims to provide a ball launcher that can prevent balls from turning back and improve the operating rate of an electric game machine.

(d) Means and operation for solving the problems In order to solve the above problems, the ball launcher for an electric game machine of the present invention includes a launcher that hits and launches a ball, and a launcher that has a firing strength that A device comprising a firing intensity setting means that sets the firing intensity in conjunction with the amount of operation of the handle, and a launcher driving means that drives the firing device to fire, wherein the amount of operation of the handle is detected and the firing intensity is set within a predetermined range. The present invention is characterized in that it includes a firing intensity detection switch that operates the firing device driving means only when the firing device is in the firing position. Therefore, if the amount of operation of the handle is small and the ball is turned back, the firing action will not be performed, and the firing action will only be performed when the firing strength is such that the ball reaches the game board. This makes it possible to improve the operating rate of the electric gaming machine.

(e) Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

FIG. 1 is a view of the ball launcher according to the embodiment as seen from the back of the pachinko machine, and FIG. 2 is a brochure diagram illustrating the circuit configuration of the ball launcher.

FIG. 1(a) shows a state in which the handle is not rotated. 2a indicates the rotation axis of the handle 2 (see FIG. 2). A lever 3 is attached to this rotating shaft 2a, and a screw 3a
It is fixed by. Further, the screw 3b on the lever 3 is fitted into the groove 4b of the fan-shaped firing strength setting member 4 made of resin. The firing intensity setting member 4 is rotatable about a shaft 4a, and is biased by a coil spring 5 in the clockwise direction of rotation in FIG. 1(a). In FIG. 1(a), the firing strength setting member 4 shown by a solid line shows a state in which the handle 2 is not rotated. On the other hand, 41 indicated by the two-dot chain line
．． 1 shows the firing intensity setting member at the maximum firing intensity. The firing intensity setting member 4 rotates in the left rotation direction in FIG. 1(a) in conjunction with the handle 2, and when the handle 2 is released from the handle 2, the coil spring 5 returns to the state shown by the solid line.

An arc-shaped magnet 27 is provided on the outer peripheral surface 4d of the firing strength setting member 4.
is installed. Further, a reed switch 26 is fixed to this outer circumferential surface 4d at a distance of 5n.

The firing strength setting member 4 is provided with a support 4C for the launcher 6. The launcher 6 is urged by the coil 2.10 and comes into contact with this support 4c.

The launcher 6 has a base end 6a rotatably supported by a shaft 9, and this base end 6aζ is provided with an arc-shaped slot 6.
b is provided. On the other hand, at a substantially central portion 6d and a tip portion 6e of the launcher 6, bins 7a and 7b are provided with coil bars $8a and 8b, respectively. Note 11
is a stopper for the launcher 6.

The working pin 12a of the link 12 is inserted into the slot 6b. Furthermore, the link 12 is rotatably connected to the movable core 13a of the solenoid 13 by a pin 12b. The part of the slot 6b closest to the solenoid 13 (
The working bottle 12a is in contact with the raw part) 6c, and the firing device 6
The suction force of the solenoid 13 is transmitted to. Figure 1(a)
This shows a state in which the movable iron core 13a is at the suction point, but at this time, a small gap G is left between the raw portion 6c and the working bottle 12a.

The lever 14 and the arm 15 are mounted on the ball firing guy F'19.
It constitutes a mechanism for replenishing pachinko balls 21. The lever 14 and the arm 16 are rotatable around screws 15 and 17, respectively, and one end 14b of the lever is in contact with the bent arm 16a. A ball pushing part 16b is provided at the tip of the arm 16. 18 is a stopper that restricts the rotation of the lever 14.

The pachinko balls 2bi supplied on the ball launch guide 19 roll to the left in the plane of FIG. 1(a), hit the ball stopper 20, and stop there.

The solenoid 13 is driven by a drive pulse output from the solenoid 23 (see FIG. 2). The solenoid drive circuit 23 operates only when the touch switch 25 and the reed switch 26 are both turned on. The touch switch 25 detects that a human body touches the touch detection section 2b of the handle 2 and turns on. The firing stop switch 24 is required by law, and is composed of, for example, a normally closed button switch, and is located near the handle 2 (reference numeral 37 in FIG. 4). When this firing stop switch 24 is pressed, even if the touch switch 25 and reed switch 26 are on, the solenoid drive circuit 23
stops.

Next, the operation of the ball launcher according to the embodiment will be explained.

The state shown in FIG. 1(a) is a state in which the handle 24 is not rotated. In this state, the reed switch 26 and the magnet 27 are separated from each other, so they are not turned on, and even if a human body touches the touch detection section 2b and the stop switch 25 is turned on, the firing operation is not performed.

As the handle 2 is rotated, the firing intensity setting member 4 rotates to the left in the drawing (a) of FIG. 1, and the firing pattern 6 also falls to the left in the drawing. As the firing pattern 6 falls down, the tickback of the firing hammer 6 increases accordingly, increasing the firing strength. However, while the firing intensity is low, the reed switch 26 is still off and no firing operation is performed.

When the handle 2 is rotated until the firing strength reaches such a level that the ball hits the game board [Fig. 1(b)
(C)], the magnet 27 approaches the reed switch 26, and the reed switch 26 is turned on.

At this point, the solenoid drive circuit 23 operates for the first time, and a firing operation is performed.

In FIG. 1(b), when a driving pulse is applied to the solenoid river 3, the movable core 13a is attracted, and an impact force is applied to the firing hammer printing part 6C to rotate the firing member 6 in the clockwise rotation direction in the paper. A force is added. Then, the firing mode 6 rotates in the clockwise rotation direction, and the pin 7b hits the pachinko ball 21', which is stopped at the strike and the ball 20, and fires it to the right and upward in the paper.

At the same time, the pin 7a hits the tip 14a of the lever 14,
Rotate the lever 14 in the counterclockwise rotation direction in FIG. 1(C). Along with this, the arm 16 rotates in the right rotation direction on the paper.
The next pachinko ball 21 is pushed up onto the ball launch guide 19. Note that the strike and collar 11 restrict the movement of the firing pattern 6 so that the firing pattern 6 does not rotate more clockwise than necessary.

Thereafter, the firing member 6 is rotated in the counterclockwise direction by the biasing force of the coil spring 10, and returns to the state shown in FIG. 1 (1). At this time, the raw portion 6C hits the working pin 12a and the movable iron core 13a is pulled out from the suction point. The arm 16 and the lever 14 return to their original states due to the weight of the arm 16.

When the handle 2 is further rotated, the firing operation is performed with a higher firing strength. When the ball is fired at a strength greater than that required to reach the game board, any part of the magnet 27 keeps the reed switch 26 in the on state.

In addition, in Figure 1 (al), the raw portion 6C and the working pin 12a are
The reason why the gap G is provided between the two is as follows. Suppose that the touch switch 25 and the reed switch 26 malfunction and are both turned on while the handle 2 is not in contact with the human body.

A drive pulse is applied to the solenoid 13, and the movable iron flood control unit 3
a is attracted to the suction point, but because of the gap G, the firing pattern 6
No force is applied to the firing action. Moreover,
- Once the movable iron core 13a is attracted, this movable iron core 13
Since a is not pulled out by the firing pattern 6, the movable iron core 13a does not move no matter how many driving pulses are applied thereafter. Therefore, it is possible to prevent a strange situation in which an unoccupied board switch malfunctions, causing a firing operation and producing a firing sound.

Although this embodiment uses a reed switch 26 to detect the rotation angle of the handle 2, it is also possible to use a Hall IC or magnetic resistance instead of the reed switch. Further, as shown in FIGS. 3(a) and 3(b), projections 4e and 4f are provided on the firing intensity setting member 4, and the projections 4e and 4f are provided on the firing intensity setting member 4.
A configuration is also possible in which f is detected by a microswitch 28 and a photoelectric switch (photointerrupter) 29, respectively. Furthermore, a configuration is also possible in which a metal body is provided in the emission intensity setting member 4 and this metal body is detected by a proximity switch.

Further, in the above embodiment, the amount of operation of the handle is indirectly detected on the firing strength setting member 4 that is linked to the handle 2, but a switch for detecting firing strength may be provided directly on the handle 2. The design can be changed as appropriate.

Further, in this embodiment, a solenoid is used as the firing hammer driving means, but the present invention is also applicable to the case where a morph is used.

(f) As described in detail of the invention, the ball firing device of the electric game machine of the present invention detects the amount of operation of the handle and operates the firing mallet driving means only when the firing intensity is within a predetermined range. Since it is characterized by being equipped with a firing intensity detection switch that causes the ball to bounce back, it has the advantage of being able to prevent balls from turning back and increase the operating rate of the electric game machine.
