ABSTRACT:
A quick selection of a depression key provided with a remote controller is impeded, so that controllable characteristics of the remote controller are deteriorated, and a lifetime of a cell provided on the side of the remote controller is reduced in order to acquire transport motional information.While a remote control system is equipped with the remote controller and an infrared communication apparatus33, a pattern for reflecting diffraction light by illumination light is provided with the remote controller, whereas a transmitting/receiving unit37and a control unit39are provided with the infrared communication apparatus33. A light emitting unit11for emitting light to the pattern, and a light receiving unit17for receiving reflection light from the pattern are provided with the transmitting/receiving unit37. A detecting unit41for detecting intensity of the light received by the light receiving unit17, a calculating unit43for binary-processing the intensity of the detected light to obtain binary information in response to the intensity of the detected light, and a converting unit45for converting the binary information into a control signal for a main appliance are provided with the control unit39.
