Claims

[Scope of utility model registration request]

A plurality of infrared transmitting devices that emit an infrared signal to a predetermined area below the infrared transmitting device are installed at a predetermined interval, and position information from the controller that specifies the position of each of the infrared transmitting devices is placed on the infrared signal and the In the infrared transmitting device configured to irradiate an area, the infrared transmitting device includes a light emitting element that transmits the position signal as an optical signal in a direction substantially perpendicular to the irradiation direction, and a light emitting element that transmits the optical signal from the adjacent infrared transmitting device. An infrared transmitting device characterized by having a light receiving element that receives light.
