ABSTRACT:
An improvement in optical remote-control apparatus which comprises a light-beam transmitter and a light-receiver, wherein the improvement is that a light-scattering (i.e., light-diffusing) plate having a suitable area is provided in front of the light-receiver, so that the aiming tolerance of the light-beam transmitter becomes broader, enabling easy remote-control.
