Abstract

A control system includes a controlled apparatus adjusting its operation based on a control signal from an independently cased control apparatus. The controlled apparatus includes an indicator light projector projecting indicator light in an invisible wavelength region so that an exiting direction thereof has a known regularity and change over time, a response signal receiver receiving a response signal in response to light reception from the control apparatus having received the indicator light, a relative position recognizer recognizing a relative position of the control apparatus to its housing based on the response signal, and an adjuster performing predetermined adjustment based on the recognition. The control apparatus includes an indicator light receiver receiving the indicator light, a response signal forming unit forming a response signal for the relative position recognizer, and a response signal transmitter transmitting the response signal toward the response signal receiver of the controlled apparatus.

Dependent claims

A control system comprising a controlled apparatus configured to adjust an operation mode of itself based on a control signal supplied from outside of a housing of itself and a control apparatus having an independent casing that can be located in a position separated from the controlled apparatus and configured to emit the control signal to the controlled apparatus,

the controlled apparatus including an indicator light projector that projects indicator light having a directivity of light in a wavelength region substantially within an invisible region so that an exiting direction thereof may have a known regularity and change over time, a response signal receiver that receives a response signal emitted in response to light reception from the control apparatus that has received the indicator light from the indicator light projector, a relative position recognizer that recognizes a relative position of the control apparatus to the housing of itself based on the response signal received by the response signal receiver, and an adjuster that performs predetermined adjustment operation based on the recognition by the relative position recognizer,
the control apparatus including an indicator light receiver that receives the indicator light emitted from the indicator light projector of the controlled apparatus, a response signal forming unit that forms a response signal on which the relative position recognizer of the controlled apparatus relies for recognizing the relative position based on the indicator light received by the indicator light receiver, and a response signal transmitter that transmits the response signal formed by the response signal forming unit toward the response signal receiver of the controlled apparatus.
