DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball hitting device for an electric pachinko machine.

[0002]

2. Description of the Related Art Conventionally, a hitting device for an electric pachinko machine is disclosed in, for example, Japanese Patent Publication No. 4-52154.
It is common practice to separately mount a launch rail and a ball hammer on the surface of a hollow box frame-shaped set plate. For this reason, when mounting the launching rail and the hitting hammer so that the center of the pachinko ball supplied to the firing rail coincides with the axis of the tip of the hitting hammer, the motor that drives the hitting hammer uses a hollow box frame-shaped set. It is extremely difficult to adjust the position because it is placed in the board.In addition, if the center of the hammer and the launch rail is misaligned due to the vibration at the time of hitting, poor hitting will occur. Was. Furthermore, since the motor is housed in a hollow box frame-shaped set plate of the set plate, the heat of the motor is easily trapped, which may cause unstable output,
There was also a problem that the set plate was distorted due to heat, the mounting position of the launch rail and the hitting hammer was shifted, and the hitting ball became unstable.

[0003]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems, is easy to assemble, has no misalignment due to vibration, enables stable hitting for a long period of time, and can be distorted by heat or output can be reduced. An object of the present invention is to provide a hitting device for an electric pachinko machine that does not become unstable.

[0004]

According to the present invention, a plate-like portion is extended on one side of a mounting board provided below a game board (2), and a firing rail and a ball hammer are provided on the front face of the mounting board. and a hit ball assembly and a drive mechanism integrated in the substrate for driving the stopper and hitting hammer for restricting the swinging of the ball striking ball mallet, the
The drive mechanism is located on the back of the plate and communicates with the outside.
The heat of the drive mechanism is dissipated to the outside .

[0005]

The hitting device for an electric pachinko machine of the present invention is a device in which a hitting hammer repeats intermittent swinging motion by a driving mechanism by a hitting operation by a player, and hits a pachinko ball supplied to a firing rail intermittently. However, the ball hitting assembly attached to the front of the mounting board provided below the game board integrates the launch rail, hitting hammer, stopper, drive mechanism, etc. with the board, so that the firing rail The hitting hammer does not cause misalignment, and the driving mechanism is disposed on the back surface of the plate-like portion projecting from one side of the mounting plate and is communicated with the outside. The output of the ball is not unstable, and there is no misalignment between the firing rail and the hitting hammer due to thermal distortion of the hitting ball assembly, so that a stable hitting can be performed.

[0006]

Next, the present invention will be described in detail with reference to the illustrated embodiment. Reference numeral 1 denotes a mounting board provided below the game board 2, and a plate portion 3 is protruded from one side of the mounting board 1. Reference numeral 4 denotes a ball hitting assembly which is screwed to the front surface of the mounting board 1, and the ball hitting assembly 4
Hammer 7 and stoppers 8 and 9 for regulating the swing of hammer 7
And a drive mechanism 10 for intermittently swinging the hitting ball 7. The firing rail 6 is obtained by covering a plastic base 11 attached to the substrate 5 with a wear-resistant rail plate 12.

Reference numeral 13 denotes a ball receiving portion formed between the ball receiving tapered surface 15 of the holder 14 for holding the cushioning rubber of the stopper 8 and the base end of the firing rail 6, and a pachinko machine set in the ball receiving portion 13. The hitting ball 7 is mounted so that the center of the ball coincides with the axis of the tip 7a of the hitting ball 7. 16 is a bearing 18 for supporting a shaft 17 to which the ball-hitting hammer 7 is attached, 1
A bearing consisting of 8 and a bearing case 19, 20 is a magnet fixed to a magnet case 21 and arranged around the shaft 17, 22 is a four electromagnet unit attached to the substrate 5 and facing the magnet 20. The electromagnet 23 of the electromagnet unit 22 has a base plate 24
A coil 26 is wound around an iron core 25 fixed to the electromagnet unit 22. The electromagnet unit 22 is a drive mechanism 10 that is controlled by a control circuit (not shown) to alternately generate magnetic fields having different polarities, and swings the hitting hammer 7. . 27 is a cover of the drive mechanism 10 and 28 is a nut for fixing the ball hammer 7 to the shaft 17.

[0008] With the above-described structure, the substrate 5 has a firing rail 6, a hitting hammer 7, stoppers 8 and 9, a driving mechanism 10
Is attached to the front surface of a mounting board 1 provided below the game board 2, and a plate-shaped portion 3 protruded from one side of the mounting board 1 by a ball hitting operation by a player with a handle (not shown). The drive mechanism 10 arranged on the back of the device operates, and the electromagnet unit 22 facing the magnet 20 alternately generates magnetic fields having different polarities.
Since the magnet 20 swings and the shaft 17 to which the magnet 20 is attached repeats forward and reverse rotation, the ball hammer 7 fixed to the shaft 17 with the nut 28 intermittently swings between the stoppers 8 and 9. Will be repeated repeatedly.

For this reason, the ball receiving taper surface 1 of the holder 14 for holding the base end of the launching rail 6 and the buffer rubber of the stopper 8.
The pachinko ball intermittently supplied to the ball receiving portion 13 formed between the five balls is accurately hit by the hammer tip 7a of the hitting hammer 7 whose axis coincides with the center of the pachinko ball of the ball receiving portion 13. The pachinko game is performed. A violent impact is intermittently applied to the hammer 7 by the operation of hitting the pachinko ball. However, since the hammer 7 and the launch rail 6 are a hammer assembly integrated with the substrate 5, Even if the impact is intermittently applied, the firing rail 6 and the ball hammer 7
Position is not shifted, and a stable hit ball can be performed for a long time.

The drive mechanism 10 is mounted on one side of the mounting plate 1.
Since the rear surface of the protruding plate-shaped portion 3 is arranged so as to communicate with the outside, even if the drive mechanism 10 operates for a long time, heat is dissipated without being trapped, and the drive mechanism 10 does not overheat. Since the output does not become unstable and the substrate 5 is not distorted due to heat, there is no misalignment between the firing rail 6 and the hitting hammer 7 so that a hitting defect does not occur and the output is always stable. Can hit the ball. In addition,
In the embodiment, the electromagnet unit 22 is used for the drive mechanism 10, but a motor may be used as a matter of course.

[0011]

According to the present invention, as apparent from the above description, the hitting hammer, the launching rail, the driving mechanism and the like are integrated into a substrate to form a hitting assembly. There is no misalignment, stable shots can be performed for a long period of time, and the drive mechanism is arranged on a plate-like portion that protrudes from the mounting board, so that the heat of the drive mechanism is constantly dissipated and the basket Since there is no waste, the output becomes unstable due to heat, the substrate is distorted by heat, and the center of the hammer of the hitting hammer and the launch rail do not become misaligned, so that a stable hit ball can be always performed for a long time. In addition, since the ball hitting device can be incorporated into the electric pachinko machine simply by attaching the ball hitting assembly to the mounting board, the operation of adjusting the mounting position becomes unnecessary and the assembling operation can be performed quickly. Furthermore, since there is no misalignment between the firing rail and the hitting hammer due to the hitting ball, there is no need for maintenance and inspection, and there are various advantages such as a reduction in running cost. Accordingly, the present invention is very large ones lath gains were also the industry as an electric pachinko machine hitting device which has solved conventional problems.
