Title: Wireless switch system
Inventor: HORII TAKASHI
IPC: H04Q9/00
Filed: 1990-09-14
Abstract: PURPOSE:To omit the power supply provided at the operating device side by attaining a constitution where an operating device modulates the light projected from a controller and then makes the light reflect for transmission of a control signal to the controller. CONSTITUTION:A rotary plate 24 is revolved with push of an operating part 22. At the same time, the light projected from a controller 1 is reflected by the controller 1 through a reflecting part 21 as shown by an arrow in accordance with the revolution of the plate 24. That is, the reflection of the light is intermitted according to the forming position of a square hole of the plate 24 and an optional pulse signal is transmitted to the controller 1. Therefore the controller 1 can receive the control signal for control of the lighting of an illuminator 3 by detecting the modulated component of the light sent back from a device 2. Then the controller 1 controls the operation of the illuminator 3 in response to the control signal. Thus no electric circuit is needed for transmission of the control signal and no power supply is needed at the side of the device 2. As a result, no exchange of batteries is required for a power supply and furthermore the shape of the controller is miniaturized.
