Abstract
Abstract A pneumatic operating device particularly suited for a video boxing game machine in which a displayed boxer is made by a player to fight against an opponent. The device comprises an air chamber (A) whose volume is variable by applying an impact on a slider button (18). The air chamber is connected through a pressure transmission passage (B) to a pressure sensor which (C) detects the pressure variation within the air chamber to produce a corresponding electric signal for controlling the displayed boxer.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
136 words
A game machine comprising: display means for displaying an image or images controlled by a player or players; at least one pneumatic operating device, said pneumatic operating device including a slider button which is hit by the player or players, an air chamber having a variable volume and operatively connected to said slider button in a manner such that the pressure within said air chamber varies when said slider button is hit by the player or players, a pressure transmission passage connected at one end to said air chamber, a pressure sensor connected to the other end of said passage for detecting the pressure therein, and means, responsive to said pressure sensor, for producing signals which vary as a function of the intensity of the impact applied to the slider button by the player or players.
Claim 2
Dependent Claim
136 words
A game machine comprising: display means for displaying an image or images controlled by a player or players; at least one pneumatic operating device, said pneumatic operating device including a slider button which is hit by the player or players, an air chamber having a variable volume and operatively connected to said slider button in a manner such that the pressure within said air chamber varies when said slider button is hit by the player or players, a pressure transmission passage connected at one end to said air chamber, a pressure sensor connected to the other end of said passage for detecting the pressure therein, and means, responsive to said pressure sensor, for producing signals which vary as a function of the intensity of the impact applied to the slider button by the player or players.
