DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball and ball game machine such as a pachinko machine and an arrange ball machine.

[0002]

2. Description of the Related Art In a ball-and-ball game machine such as a pachinko machine, a lower plate unit is arranged on a front surface of a lower portion of a front frame in addition to a upper plate for supplying game balls one by one to a launch means side. When the game balls are full, the game balls overflowing or withdrawn from the upper plate are guided to the lower plate unit side through the ball guide gutter, and the game balls are stored in the lower plate unit. Conventionally, as described in JP-B-62-26792, the lower plate unit includes a lower plate body integrally provided with a lower plate portion, and a lower plate cover attached to a required portion of the lower plate body. And an ashtray is provided in a part thereof. And, between the lower plate main body and the front frame, a decorative plate having a ball guide port for guiding the game ball from the back side of the front frame to the lower plate is interposed,
Providing three mounting bolts protruding backward from the lower plate body, inserting these mounting bolts through the decorative board and the front frame,

Front frame 2 with mounting boss 55 and mounting screw 63
Can be fixed together. Also, since the mounting bosses 55 on both the left and right sides of the ball guide port 54 are located between the left and right mounting bolts 52, even if the distance between the left and right mounting bolts 52 is increased, the decorative plate 41 and the lower plate body 38 can be securely fixed to the front frame 2 And the number of mounting bolts 52 can be reduced.

According to the third aspect of the present invention, the mounting bosses 57, 89 projecting rearward from above the ball guide port 54.
Is provided above the decorative plate 41 and / or the lower plate cover 39, and the front frame
Mounting screws 65, 66 inserted from the back side into mounting portions 29 of the support plate 17 mounted on the back side of the base plate 2 and supporting the game board 7 from below, are screwed into the mounting bosses 57, 89. 41 and / or the lower plate cover 39 and the support plate 17 can be fixed to the front frame 2 together with the mounting bosses 57 and 89 and the mounting screws 65 and 66, and the decorative plate 41 and / or the lower plate cover 39 can be fixed. The upper side can be securely fixed to the front frame 2. Claim 4
According to the present invention, mounting bosses 91 and 92 projecting rearward from the decorative plate 41 and the lower plate cover 39 are provided, and the mounting bosses 91 and 92 are inserted from the back side into the mounting plate 31 of the firing means 12 abutting on the back side of the front frame 2. Since the mounting screws 98 are screwed into the mounting bosses 91 and 92, the decorative plate 41 and the lower plate cover 39 and the mounting plate 30 of the firing means 12 can be fixed to the front frame 2 together.
