ABSTRACT:
An office machine is disclosed, which comprises a second (lower) unit and a first (upper) unit capable of being opened and closed with respect to the lower unit. A plurality of light-emitting elements and a plurality of light-receiving elements are provided in the lower unit, and a plurality of light-emitting elements and a plurality of light-receiving elements are provided in the upper unit. The control signal and data signal are fed to the light-emitting elements to be converted into optical on-off signal. The light-receiving elements receive the optical signal and convert it into electric signal which is fed to necessary parts. Control signal lines and data signal lines between the two units are thus replaced with an optical relay.
