Title: Game machine
Inventor: SAWADA MORIHIRO
IPC: A63F7/02
Filed: 2019-02-11
Abstract: To easily operate operation parts while downsizing a terminal board on which many terminals and operation parts are provided.SOLUTION: Multiple operation parts are provided movably across a direction in which the operation parts are arranged side by side, and the operation parts are moved, thereby switching a state where a cable can be fixed and a state where the fixture is cancelled for each terminal. A range of movement of each operation parts is provided differently from a range of movement of a neighboring operation part. Thus, when moving one operation part, since the range of movement switching the state where the cable can be fixed and the state where the fixture is cancelled is different in a neighboring operation part, the neighboring operation part is prevented from being switched by operating the one operation part. Therefore, even in a case where a terminal board is downsized by proximately providing one operation part and the neighboring operation part, the target operation part can be easily operated while avoiding the risk of switching a terminal of the neighboring operation part.SELECTED DRAWING: Figure 6
