Abstract
A recording apparatus includes a placement unit on which sheets of paper are placed, a feeder that feeds a sheet, thrust mechanisms that push up the placement unit toward the feeder, and an edge guide. Each of the thrust mechanisms includes a coil spring that imparts an urging force to the placement unit, one case that is mounted on the placement unit and receives the coil spring from one end thereof and accommodates the coil spring, and another case that is disposed so as to partially overlap the one case and receives the coil spring from the other end thereof and accommodates the coil spring. The one case and the other case are configured to be movable relative to each other in the urging direction of the coil spring and to be rotatable together in the circumferential direction.
Claims11
A recording apparatus comprising:
- a placement unit on which a recording medium is placed;
- a feeder that feeds the recording medium from the placement unit toward a recording section;
- a thrust mechanism that pushes up the placement unit toward the feeder;
- and
- an edge guide that is disposed in the placement unit and defines a position of a side of the recording medium in a direction intersecting a transport direction of the recording medium, wherein
- the thrust mechanism includes
- an urging member that imparts an urging force to the placement unit,
- a first accommodation body that is mounted on the placement unit and receives the urging member from an end thereof and accommodates the urging member, and
- a second accommodation body that is disposed so as to partially overlap the first accommodation body and receives the urging member from another end thereof and accommodates the urging member, and
- the first accommodation body and the second accommodation body are movable relative to each other in an urging direction of the urging member and are rotatable together in a circumferential direction of the first accommodation body and the second accommodation body,
- a protrusion that is disposed in the first accommodation body and that rotates the first accommodation body in conjunction with movement of the edge guide;
- a restraining portion that is disposed in the placement unit;
- and
- a restrained portion that is disposed in the second accommodation body, that rotates together with the second accommodation body in conjunction with rotation of the first accommodation body, and that is displaced between a first position at which the restraining portion restrains the restrained portion and a second position at which the restraining portion does not restrain the restrained portion,
- wherein in a case in which the restrained portion is at the first position, the second accommodation body is restrained from moving relative to the first accommodation body, and the urging member is thereby restrained from imparting the urging force to the placement unit.
