The touch probe consists of a transmitting touch probe, and a receiver head that faces the touch probe and receives the optical signal emitted from the touch probe and converts it into an electrical signal. a plurality of light emitting elements and a plurality of light receiving elements; a light emitting circuit that changes the frequency of a light emitting current flowing through the plurality of light emitting elements depending on when a built-in switch is turned on and off; When at least one of the light-receiving elements receives modulated light for operation commands from the receiver head, the light-emitting circuit is provided with a light-receiving circuit that turns on power for driving the light-emitting circuit; a light emitting element, a light emitting circuit that supplies a light emitting current with a predetermined modulation frequency to the light emitting element for operation commands only while the touch probe is in use, a light receiving element for receiving, and an output of the light receiving element. A light receiving circuit is provided which processes the received frequency, determines whether it is a high frequency or a low frequency, and generates a carry signal indicating that reception is in progress and a touch output signal indicating that an ON signal is being input.
