Abstract

PURPOSE: To use one key and photocoupler for many function operations by providing a notch part so that light from LED will be supplied to some or all of phototransistors at the fixation position of a thin surface plate.
CONSTITUTION: The photocoupler having LED and phototransistor TR opposing to each other is provided. Between this LED and TR, a thin surface plate is inserted at the fixation position. In this case, the photocoupler turns on when a notch part resides at the position of the surface plate that corresponds to the position of TR or turns off when not. For this purpose, the notch part is provided to some or all of surface plates of photocouplers, so that one key and photocoupler can be used for many function operations.
