<p><P>PROBLEM TO BE SOLVED: To increase the strength of a hinge with which a display unit is supported to a game machine frame to be freely swung singly. <P>SOLUTION: A vertical piece part 91c is spot-welded to the right side wall 115 of a metal case body 106 at a welding part 91k, and thus a hinge structure 91a is fixedly attached to the metal case body 106. A vertical piece part 91h is brought into contact with the right side wall 115 of the metal case body 106 and the vertical piece part 91c. An upper connecting piece 91i is piled up on an upper hinge piece 91d and spot-welded to the upper hinge piece 91d at a welding part 91m, and a lower connecting piece 91j is piled up under a lower hinge piece 91e and spot-welded to the lower hinge piece 91e at a welding part 91n. Thus, a reinforcing structure 91b is fixedly attached to the hinge structure 91a. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
