Abstract:
1. An optical hair removing device comprising: a light emitting unit for emitting light; an irradiation unit for irradiating the light emitted from the light emitting unit to body hairs on a skin; and a control unit for controlling the light emission unit, wherein the irradiation unit has a movement detection unit for detecting a movement of the irradiation unit on the skin, a contact detection unit for detecting a contact between the irradiation unit and the skin, and a light detection unit for detecting the light emitted from the light emitting unit and light that enters from outside to the irradiation unit through a gap between the irradiation unit and the skin when the irradiation unit is made to contact with the skin, and the control unit allows the light emitting unit to emit light if the light detection unit indicates that no light enters through the gap, when the light emitting unit is not emitting light.
