Abstract
A digital camera includes: a mirror box that defines a space in which a light flux from a photographic lens is guided to an imaging unit; a mirror unit that is arranged inside the mirror box and is configured 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; and an opening section that discharges from the mirror box air that is moved when the mirror unit is rotated.
