Description

[Detailed description of the invention] The present invention relates to a support plate structure for a pachinko machine, and more specifically, it is a pachinko machine made of synthetic resin that is attached to the front frame of the pachinko machine so that the game board can be attached from the back side. This relates to the support plate structure of the machine.

Traditionally, in order to make it possible to replace the game board on the front frame of a pachinko machine, there are machines in which a decorative plate is provided on the front frame, as shown in Japanese Patent Laid-Open No. 52-97826, and pachinko machines in which a decorative plate is provided on the front frame of the pachinko machine, as shown in Japanese Patent Laid-Open No. 52-97826. There was one in which a window frame was provided on the front frame, as shown in Publication No. 28087, and game boards were placed on the decorative board and the window frame, respectively.

Further, the decorative plate and the front frame of the above-mentioned Japanese Patent Application Laid-Open No. 52-97826 are positioned by bosses provided in the decorative plate and holes provided in the front frame, and each is attached integrally.

Generally, pachinko machines are equipped with a mechanism plate on which the back parts etc. are arranged, but in order to open the mechanism plate when replacing the game board or when the back of the game board breaks down, the mounting bracket is attached to the pachinko machine. It must be installed on the back side of the

Therefore, it is conceivable to attach the above-mentioned mounting bracket to the front frame.

However, the position of the mechanism board needs to be in an accurate position relative to the position of the game board and the prize ball outlet so that winning balls and prize balls do not get stuck. Since the positioning of the metal fittings must be carefully arranged and the mounting metal fittings must be accurately attached to the determined position, there is a problem that the work of installing the fittings cannot be carried out quickly. In addition, even if positioning is provided and the mounting bracket is installed in the correct position, the game board and prize ball outlet are provided on the support plate, so errors in installation between the front frame and the support plate will affect the installation. After the mechanism plate was attached, there was a problem in that the prize balls and prize balls would become stuck between the game board or the prize ball outlet and the mechanism plate.

The purpose of the present invention is to avoid the above-mentioned drawbacks, to be able to accurately maintain the interrelationships of each component for many years, and to
