ABSTRACT:
A shutter device includes a shutter member which rotates about a first rotational axis and a swinging arm for the shutter member by engaging the shutter member. The shutter member has an insertion preventing portion which, by being rotated by the swinging arm rotating about a second rotational axis, is positioned at a preventing position for preventing the insertion of a recording medium by covering at least a portion of an opening for inserting the recording medium and at an open position enabling the insertion and ejection of the recording medium by opening the opening. Engaging portions of the shutter member and the swinging arm are provided between the first rotational axis and the position of the insertion preventing portion in the shutter member.
