Abstract
A digital camera includes: a light guide section that defines a space in which a light flux from a photographic lens to an imaging unit is guided; a mirror unit arranged inside the light guide section, that is adapted to rotate between a viewing position in which the mirror unit is inserted in a photographic light path from the photographic lens to the imaging unit to reflect the light flux and a photographing position in which the mirror unit is retracted from the photographic light path; a mirror unit control section that controls rotation of the mirror unit; a rotation instruction section that outputs a signal to rotate the mirror unit while no photography is performed to the mirror unit control section; and an opening section provided in the light guide section that discharges from the light guide section air that is moved by the rotation of the mirror unit.
