DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art As shown in FIGS. 3 and 4, a ball launching device for a conventional pachinko machine has a rotary shaft of a hammer disposed below a launching rail and stops at the rear end of the ball launching rail 10. Ball 1
The tip 12a of the hammer 12 hitting the ball 1 makes the arc-shaped trajectory CC passing through the hit point P of the ball 11 intersect with the straight line AA which is the trajectory of the ball 11 and is directed downward. It is designed to press against the firing rail. 13 is a hammer driving source.

[0003]

In the above-mentioned prior art, the tip 11a of the hammer 12 rotates about a lower axis and stops at the firing position of the ball firing rail 10.
Since the rear end is struck in an arc-shaped trajectory C-C direction toward downward somewhat from the ball firing trajectory A-A, since the component force F ₁ of the force F applied to the striking hammer 12 strikes applied to the ball 11 since the component force F ₂ toward the downward presses the ball after firing the firing rail,
There was a problem that the power to fly the ball was lost by that much.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to provide a pachinko ball on a pachinko game board.
Pachinko balls to induce pachinko balls on the game board surface
Guide rails for launching
Rotating hammer in launching device with launching hammer and power source
The axis is arranged above the ball firing position, and the ball is straight when firing.
The arc-shaped trajectory of the tip of the hammer relative to the trajectory is the linear trajectory.
And a tangent upward .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIG.
1 is a firing rail of a pachinko machine, 2 is a ball stopped at the firing position of the firing rail 1, and AA is a trajectory in the firing direction of the ball. Reference numeral 3 denotes a hammer, wherein the rotary drive source 4 is disposed above the firing position, and the hitting point at which the tip of the hammer 3 hits the ball 2 is P, and the tip 3a of the hitting hammer 3 has a ball hitting point P from above.
, And an arc-shaped trajectory B-B further upward to the firing rail 1
And the linear firing trajectory of the ball 2 is the arc-shaped trajectory BB
It is determined to be tangent to. Next, the operation will be described. The hammer starts almost vertically below the axis of rotation and the ball
When the ball is hit, the tip trajectory of the hammer 3 draws an arc-shaped rotation trajectory BB from above the straight firing trajectory rear extension line AA to the hitting point P, and further upward to the firing rail 1, and The straight firing locus A-A is tangent to the arc-shaped locus. Therefore, the force F applied to the hammer tip 3a is applied to the ball 2 without any loss. Furthermore, ball 2
After the impact, the hammer tip 3a moves while pushing the ball 2 upward, so that the frictional force between the firing rail 1 and the ball 2 is small.

[0006]

As described above, the present invention provides a pachinko game
Pachinko balls to induce pachinko balls on the game board
Guide rails for launching towards the guide rails
Hammering and launching equipment with power source
The driving axis is placed above the ball firing position, and the straight line when the ball is fired
The circular locus of the tip of the hammer is different from the linear locus
Since the trajectory has an upward tangent, the force applied to the hammer is applied to the ball as it is, and the ball after firing moves on the firing rail while pushing upward, so frictional force with the firing rail And the ball can be effectively hit with a small force.
