a protective film disposed over the sensing plane of the sensor and having a band shape to be wound; and
a moving unit installed in the housing and configured to move the protective film while maintaining a position of the protective film with respect to the sensing plane of the sensor,
wherein the moving unit includes:
a first roller configured to wind the protective film and installed in the housing;
a second roller spaced apart from the first roller, disposed in the housing, and configured to wind the protective film unwound from the first roller; and
a driver configured to generate a driving force for rotating the second roller.
