<P>PROBLEM TO BE SOLVED: To provide a game machine capable of operating a movable part without being affected by a play provided in a transmission mechanism. <P>SOLUTION: A first slide plate 531 whose one end is pivottaly supported by a swinging shaft 541 and whose another end is mounted with a light-emitting display 800, is connected to a lifting/lowering arm 534 with a play via a connecting pin 563. The lifting/lowering arm 534 is constantly energized upward by a tension spring 535 at a position between a lifted position and a lowered position, an upward energizing force (F1) applied to the light-emitting display 800 by the tension spring 535 is smaller (F1<F2) than a downward force (F2) applied to the tension spring 535 by the own weight of the light-emitting display 800 when the light-emitting display 800 is located at the lowered position, so as to prevent a temporary stop of the lifting/lowering movement caused by a phenomenon that the F1 and F2 are balanced on the way of the lifting/lowering. <P>COPYRIGHT: (C)2012,JPO&INPIT |
