Abstract: A pull-in apparatus configured to pull in a unit toward a predetermined position in an apparatus body includes an arm member, a restriction member, a first action portion and a second action portion. The restriction member is movable between a lock position at which the restriction member restricts movement of the arm member in a first direction and a lock-release position at which the restriction member allows the movement of the arm member in the first direction. Movement of the restriction member from the lock position toward the lock-release position is restricted in a state in which the arm member is at a stand-by position, and is allowed in a state in which the arm member has been moved from the stand-by position in a second direction.

The restriction member is movable between a lock position at which the restriction member restricts movement of the arm member in a first direction and a lock-release position at which the restriction member allows the movement of the arm member in the first direction. Movement of the restriction member from the lock position toward the lock-release position is restricted in a state in which the arm member is at a stand-by position, and is allowed in a state in which the arm member has been moved from the stand-by position in a second direction.

Abstract: The sheet feeding apparatus includes a stacking device on which a sheet is stacked, a feeding device, which is configured to feed the stacked sheet, a contact portion arranged at a position at which the stacked sheet is brought into contact with the contact portion, and a moving member, which is movable in a direction in which a protruding amount of the stacked sheet changes.

Abstract: A sheet conveying apparatus includes a rotating member to covey a sheet and a drive transmission having a first, gear in a first engaging portion, a second gear in a second engaging portion, and an urging member. In a state where the first engaging portion and the second engaging portion are engaged with each other and the first gear is rotating in a first direction, a first surface of the first engaging portion transmits a driving force of a driving source from the first gear to the second gear. The first surface is inclined so that either engaging portion can retract, in the direction against the urging force of the urging member, to disengage with the other engaging portion while the first engaging portion rotates. A direction of twist of helical teeth in the first gear is configured to generate an axial force with respect to the urging direction.
