Description

[Detailed Description of the Invention] The present invention relates to the structure of a firing section in a pinball game machine that fires game balls from the upper side of the game board, and its purpose is to: Firing in a pinball game machine in which the firing part is formed of a metal band plate and is bent in a concave shape so that the firing operation of game balls can be performed smoothly and accurately. It provides the structure of the section.

An example of implementing the present invention will be described below with reference to the drawings.

Fig. 1 is a front view of the pinball game machine, in which 1 is a front frame with a window hole attached to the front of the game machine body, and a glass frame 2 is provided to cover the window hole so that it can be opened and closed. .

A game board 3 is provided on the inner surface of the table frame 1, and a game ball launching device 4 is provided near the upper side of the game board 3.

Guide rails 5 are arranged in an arc shape upwardly from the firing device 4, and a guide frame 6 is provided downward from the firing device 4 along the sides of the glass frame 2.

2 and 3 show the launching device 4,
The firing device 4 takes the form of a plastic box 8 having a cavity 7 inside, and the box 8 is removably attached to the upper side of the game board 3.

As shown in FIG. 3, in the upper part of the empty space 7 of the box 8, passage walls 9a and 9b are projected upward and downward to form a passage 10 for game balls having a gentle slope. 1
A firing section 11 is provided at the lower end of the slant, and an opening 12 is provided at the upper end of the slant.

In addition, in the ball passage 10, there is a waiting part 13 formed in an arc shape on the passage surface near the opening 12 and having a function of storing one game ball. As shown in FIG. 2, a ball introduction port 14 is drilled through the ball.

A firing hammer 15 is arranged along the lower surface of the passage wall 9a forming the passage 10 for game balls.

The firing hammer 15 is integrally equipped with a control piece part 16 for sequentially sending out the game balls located in the standby part 13 to the firing part, and a hammer head 17 at the tip is positioned so as to fire the game balls in the firing part 11. Reference numeral 18 indicates a firing port opening at a corner of the box 8 located above the firing part 11, respectively.

In the present invention, as shown in FIG.
and the inclined end of the lower passage wall 9a forming the ball passage 10 are formed into a concave shape so as to hold the game balls stationary, and the hammer head 17 of the firing hammer 15 is formed on the lower surface thereof.
This is achieved by providing a through hole 20 through which the particles can enter.

Since the present invention has the above-mentioned structure, the firing hammer 1
5, the control piece part 16 rushes into the opening part 12, pushes the game balls located in the standby part 13, and transfers the game balls to the firing part 11 through the ball passage 10.

Then, by the instantaneous hitting action of the hammer head 17 of the firing hammer 15, the game balls in the firing section 11 are thrown into the firing port 18.
It is fired to the game section 3a of the game board 3.

Therefore, since the firing section 11 is formed by the metal band plate 19, when the hammer head 17 fires the game balls, the game balls are not easily released, and a smooth firing operation is possible.

Moreover, since the ejecting section 11 is shaped like a concave, the game balls transferred to the ejecting section 11 quickly sit in the through holes 20 of the metal band plate 19 without any play and are stabilized. This allows for extremely accurate firing operations.
