Abstract

A conveyor includes: a first roller; a second roller opposed to the first roller; a roller holder including a roller supporter; a frame supporting the roller holder and having a first surface and second surface; and a moving member that is moved to move the roller supporter. The roller holder includes: a contact portion that is located upstream of the roller supporter in a conveying direction and contacts the second surface; a thin portion disposed between the roller supporter and the contact portion; and an engaging portion engaged with the moving member at a position located downstream of the thin portion in the conveying direction. The roller supporter is moved from a first position to a second position by bending of the thin portion, which bending is caused when the engaging portion is moved away from the second roller with movement of the moving member.

Dependent claims

A conveyor, comprising:

a first roller;
a second roller opposed to the first roller and configured to convey a sheet in a conveying direction in which the sheet is nipped between the first roller and the second roller;
a roller holder comprising a roller supporter that supports the second roller rotatably, the roller supporter being movable between a first position at which the second roller is in contact with the first roller and a second position at which the second roller is spaced apart from the first roller;
an urging member that urges the roller holder such that the roller supporter is moved toward the first position;
a frame formed of metal and supporting the roller holder;
and
a moving member that is moved to move the roller supporter between the first position and the second position,
the frame comprising:
a first portion comprising a first surface that contacts the urging member;
and
a second portion located upstream of the first portion in the conveying direction and comprising a second surface substantially orthogonal to the first surface and the conveying direction,
the roller holder comprising:
a contact portion that is located upstream of the roller supporter in the conveying direction and contacts the second surface from a downstream side in the conveying direction;
a thin portion disposed between the roller supporter and the contact portion in the conveying direction and having a thickness less than that of each of the roller supporter and the contact portion in a direction of movement of the roller supporter;
and
an engaging portion that is engaged with the moving member at a position located downstream of the thin portion in the conveying direction,
the roller supporter being configured to be moved from the first position to the second position by bending of the thin portion, which bending is caused when the engaging portion is moved away from the second roller with movement of the moving member.

An ink-jet recording apparatus, comprising:

a conveyor comprising (i) a first roller, (ii) a second roller opposed to the first roller and configured to convey a sheet in a conveying direction in which the sheet is nipped between the first roller and the second roller, (iii) a roller holder comprising a roller supporter that supports the second roller rotatably, the roller supporter being movable between a first position at which the second roller is in contact with the first roller and a second position at which the second roller is spaced apart from the first roller, (iv) an urging member that urges the roller holder such that the roller supporter is moved toward the first position, (v) a frame formed of metal and supporting the roller holder, and (vi) a moving member that is moved to move the roller supporter between the first position and the second position, the frame comprising (a) a first portion comprising a first surface that contacts the urging member;
and (b) a second portion located upstream of the first portion in the conveying direction and comprising a second surface substantially orthogonal to the first surface and the conveying direction, the roller holder comprising a contact portion that is located upstream of the roller supporter in the conveying direction and contacts the second surface from a downstream side in the conveying direction, a thin portion disposed between the roller supporter and the contact portion in the conveying direction and having a thickness less than that of each of the roller supporter and the contact portion in a direction of movement of the roller supporter, and an engaging portion that is engaged with the moving member at a position located downstream of the thin portion in the conveying direction, the roller supporter being configured to be moved from the first position to the second position by bending of the thin portion, which bending is caused when the engaging portion is moved away from the second roller with movement of the moving member;
a recording head disposed downstream of the first roller and the second roller in the conveying direction;
and
a platen that is opposed to the recording head and supports the sheet to be conveyed by the first roller and the second roller.
