Abstract
A scanner unit is revolvable disposed to a recording unit. The recording unit and the scanner unit are coupled with each other with a damper unit including a holder, a rod, and a spring. The damper unit is disposed so that the operating direction of the spring switches in process of the opening and the closing of the scanner unit. A guiding surface capable of abutting on the projection disposed on the rod is provided in the recording unit. The projection abuts on the guiding surface before the operating direction of the spring switches in process of the movement of the scanner unit from its opened position to its closed position.
Claims7
An image reading and recording apparatus comprising:
- a recording unit;
- a scanner unit disposed to be rotatable to the recording unit;
- a damper unit disposed between the recording unit and the scanner unit, the damper unit including a holder coupled to the recording unit, a rod movable to the holder in an expansion and contraction direction, and a spring mounted between the holder and the rod to produce a spring force in a direction of pushing out the rod, wherein an operating direction of the spring switches while the scanner unit moves from an opened position thereof to a closed position thereof to the recording unit;
- a projection disposed on the rod;
- and
- a guiding surface disposed on the recording unit to abut against the projection,
- wherein the projection abuts against the guiding surface before the operation direction of the spring switches in process of a scanner unit's movement from the opened position thereof to the closed position thereof.
