Abstract

PURPOSE:To add a ball inducing function and nail arranging function to a member installed on a game board surface by installing an operational member formed with a deflecting part for changing the rolling direction of a pinball on the game board surface. CONSTITUTION:A pair of left and right ball inducing paths 19 placed on the front end of a large-sized pattern display device 3 attached to a game board 1 and a cover plate 15 having first-fourth deflection parts 20A-20D formed except in the front position of three pattern display bodies 32 are provided on a game board surface 1a. A pinball rolling along the game board surface 1a is induced toward a big prize winning port 2a by a ball inducing path 19 to change the rebounding direction of pinball colliding with the path 19 on the way of passing therethrough by first-fourth baffle pieces 22A-22D in the first - fourth deflection parts 20A-20D. Thus, a function of rail row for changing the rebounding mode of the pinball can be ensured without using any nails and wind mill.

Are vertically installed on the left and right portions of the front relay board 31, and one front coupling connector 35 is horizontally installed on the center of the lower end of the front relay board 31.

A board housing frame 28 is provided behind the front relay board 31.
The relay board 36 is installed after the relay circuit is printed by being connected in a vertical state to the relay board 36, and the four corner portions of the relay board 36 are then mounted on the mounting surface 30 of each support piece 30 of the board housing frame 28.
It is joined to the rear end of each support piece 30 in a state where it is fixed to a by a screw 46 and held by a holding piece 30b.

The front surface of the rear relay board 36 has a large number of connection terminals connected to the relay circuit, and each front coupling connector 3
Three rear coupling connectors 37 releasably coupled to 5 are attached.

On the rear surface of the rear relay board 36, a collective connector 38 for detachably connecting the relay circuit and the wiring outside the symbol display device is attached.

Next, the operation and effect of the embodiment having the above configuration will be described. At the front end of the large-sized symbol display device 3 mounted on the game board 1, a pair of left and right ball guide passages 19 are provided.
-The 4th turning parts 20A-20D are three symbol display bodies 32.
Install the cover plate 15 formed avoiding the front position of
Guide the pachinko ball rolling along the game board surface 1a to the direction of the special winning opening 2a by both ball guide passages 19, and change the rebound direction of the pachinko ball colliding on the way through the ball guide passage 19 by changing the first to fourth directions. Facing parts 20A, 20B, 20C, 2
It is configured to be changed by the first to fourth obstacle pieces 22A to 22D of 0D.

Therefore, the ball guiding function for guiding the pachinko balls and the nail row function for changing the rebound mode of the pachinko balls can be added to the symbol display device 3, and the symbol display device 3 becomes large. Symbol display device 3 in the game board surface 1a
Occupies a large space, and the space for planting nail rows is relatively small, the ball guiding passage 19 for guiding the pachinko ball and the turning portions 20A to 20D for changing the rebounding direction of the pachinko ball are provided. It can be secured in the installation space of the symbol display device 3.

When the pachinko ball collides with a flat plastic surface, the pachinko ball rebounds without being decelerated at a rebound angle symmetrical with respect to the approach angle to the collision point.
If the pachinko ball collides with the obstacle pieces 22A to 22D of the turning portions 20A to 20D from above while the pachinko ball passes through the ball guide passage 19, the pachinko ball rebounds diagonally upward and collides with another obstacle piece again, and the pachinko ball again. Since the rebound strength of the ball is weakened, the falling speed of the pachinko ball passing through the ball guiding passageway 19 can be slowed down, and the pachinko ball staying time on the game board surface 1a can be lengthened.

As shown in FIG. 11, the wind vehicle body 24
Is attached to the partition plate 16 of the cover plate 15 in a cantilever manner, extends from the glass plate G side to the game board 1 side, and is rotatably supported by a support shaft 25A separated from the base plate 4. You may do it. According to this structure, even if the wind vehicle body 24 cannot be mounted on the game board 1 side in terms of space or material, the wind vehicle body 24 is installed in the ball guide passage 19 to adjust the rolling direction of the pachinko ball. be able to.
