Abstract
A multi-optical axis sensor according to an embodiment of the present invention comprises: a light-transmitting unit comprising a plurality of light-transmitting elements; a light-receiving unit comprising a plurality of light-receiving elements which are arranged to respectively face the light-transmitting elements and respectively receive light from the light-transmitting elements; and an indicator light indicating a light incidence state or a light blockage state of the light-receiving unit, wherein, before a muting state that invalidates the detection function of the multi-optical axis sensor is detected, the light-transmitting unit or the light-receiving unit may operate the indicator light in a light incidence/blockage mode indicating the light incidence state or the light blockage state, and when the muting state is detected, the light-transmitting unit or the light-receiving unit may switch the operation mode of the indicator light from the light incidence/blockage mode to the muting mode indicating the muting state.
