摘要

PURPOSE: To reduce the cost by molding the glass frame for Japanese pin ball game machine with synthetic resin and to take countermeasures to illegality as well although it is made into resin. ;CONSTITUTION: A front cover 3 and a glass holding member 4 consisting of a glass frame 2 are molded by a synthetic resin. First and second glass plate inserting grooves 16 and 17 are formed by a lot of projecting parts 15 at the inner peripheral part of the glass holding member 4, and a glass plate 20 is inserted to these grooves. The respective projecting parts 15 are arranged in a so-called zigzag state for three lines forward and backward so as to make the positions different in the state of not being mutually wrapped in the lengthwise direction of respective side parts 4a, 4b and 4d and to form a gap 18 for inserting the glass plate between the forward and backward sides. A cover layer 19 formed by metal plating is provided over the entire surface of the glass holding member 4.;COPYRIGHT: (C)1995,JPO
