PURPOSE:To prevent power from being wasted unwittingly by composing a controller by minimum parts and by starting and automatically stopping the device itself. CONSTITUTION:An operation element (e.g. a joy stick) moves the cursor on a display device to a desired location. The joy stick is connected with a switch circuit 9. This switch circuit 9 is turned on by pressurizing the operation element. The output signal of the such circuit, 9 is supplied to a controller 11. When the joy stick is not operated for prescribed time, the controller 11 is automatically turned off. |
