Cartridge

摘要

A cartridge may include a conveyor roller extending along a rotational axis and a bearing member for rotatably supporting the conveyor roller. The conveyor roller may include a larger-diameter portion for conveying a sheet, and a smaller-diameter portion. The bearing member may rotatably support the smaller-diameter portion of the conveyor roller, and engage the housing. In one or more arrangements, the entire smaller-diameter portion of the conveyor roller may be located at a more outward position, relative to a midpoint of the larger-diameter portion, than a portion of the bearing member supporting the smaller-diameter portion of the conveyor roller.

1. A cartridge comprising:
a housing; a sheet conveyor roller having a rotational axis, the sheet conveyor roller comprising:
a first portion configured to convey a sheet; anda second portion having a smaller diameter than the first portion, wherein the second portion extends from the first portion to an end of the sheet conveyor roller in a first direction in which the rotational axis of the sheet conveyor roller extends; and a bearing member configured to rotatably support the sheet conveyor roller, and comprising:
a support portion configured to rotatably support the second portion; andan engagement portion configured to engage with the housing, wherein, when the bearing member supports the sheet conveyor roller, an entirety of the second portion is located at a more outward position, relative to a midpoint of the sheet conveyor roller, than the engagement portion of the bearing member in the first direction in which the second portion extends from the first portion.
