An imaging apparatus is provided, including a mirror movable between a viewing position and a retracted position; a shutter which prevents the light that is passed through the imaging optical system from being incident on the image sensor and allows the light that is passed through the imaging optical system to be incident on the image sensor when open and shut, respectively; a reversible motor; a first operating mechanism which moves the mirror and carries out a shutter charge operation when engaged with the reversible motor and driven thereby; a second operating mechanism which carries out the shutter charge operation without moving the mirror when engaged with the reversible motor and driven thereby; and a driving force transmission switcher for transmitting driving forces of the reversible motor in first and second rotational directions thereof to the first and second operating mechanisms, respectively.
