ELECTRONIC EQUIPMENT SYSTEM

Title:

ELECTRONIC EQUIPMENT SYSTEM

Document Type and Number:

Japanese Patent JPH0514281

Kind Code:

A

Abstract:

PURPOSE: To realize a low-priced electronic equipment system.

CONSTITUTION: From a light emitting diode 13, the light of the wavelength of 850nm modulated by an audio signal is generated. From a light emitting diode 33, the light of the wavelength of 940nm modulated by a remote control signal is generated. Light receivers 2 and 4 respectively have optical filters 21 and 41, the optical filter 21 transmits the light generated by the light emitting diode 13 and does not transmit the light generated by the light emitting diode 33. The optical filter 41 transmits the light generated by the light emitting diode 33 and does not transmit the light generated by the light emitting diode 13. Then, a photo diode 22 receives the audio signal only outputted from a light transmitter 1. A photo diode 42 receives a remote control signal only outputted by a light transmitter 3.
