Title: Game machine
Inventor: OKAMURA GEN
IPC: A63F7/02
Filed: 2022-03-18
Abstract: To provide a game machine capable of suitably connecting operation means and a board.SOLUTION: A conductive member Q1000 is formed cylindrically from a conductive sponge. Therefore, when a liquid crystal device Q543 (a rear surface part Q543c) and a board member Q545 (a first area 545a) are displaced relatively, a difference in deformation properties of the conductive member Q1000 depending on a deformation direction can be suppressed. As a result, a change in a contact pressure and area can be suppressed, thus suppressing irregularities of a noise effect. Especially, since a first contact part Q1100 and a second contact part Q1200 cannot be deformed more easily (stiffness becomes larger) than a middle part Q1300, a contact state between the first contact part Q1100 and the second contact part Q1200, and the liquid crystal device Q543 (a rear surface part Q543c) and the board member Q545 (the first area 545a) can be easily maintained to be secure by utilizing followability of the relative displacement by deformation of the middle part Q1300 and shape stability of the first contact part Q1100 and the second contact part Q1200.SELECTED DRAWING: Figure 2149
