<p><P>PROBLEM TO BE SOLVED: To inhibit unnecessary turning of a hinge member in a game machine with a board box openably/closably coupled and fixed to the rear side of a game board via the hinge member. <P>SOLUTION: In the game machine, a first control board box is openably/closably coupled and fixed via the hinge member 90 which can turn around a turning shaft 93 (a prescribed shaft). The hinge member 90 has such a mechanism that a left locking projection 925L or right locking projection 925R is engaged with an arm metal piece 911B while urged by a coil spring 931 (urging means) as a temporarily holding mechanism which can hold the hinge mechanism 90 at a prescribed angle position (an attached position, storage position or opened position) within the turning range. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
