Title: Game machine
IPC: A63F5/04
Filed: 2022-01-28
Abstract: PROBLEM TO BE SOLVED: To provide a game machine enabling an easy grasping of an operation position of an operation part. 
     SOLUTION: When a displacement unit 395 is displaced following the operation of an operation unit, a second displacement member 397 presses a plate spring 393 and a reaction force following elastic deformation of the plate spring 393 is applied. After that, the displacement unit 395 reaches a prescribed position and when the second displacement member 397 passes the plate spring 393, application of the reaction force from the plate spring 393 is cancelled. Since the operation feeling of an operation part is changed due to the change in the reaction force, grasping of an operation position of the operation part can be made easy on the basis of the change in the operation feeling.
