Abstract
Provided is a sheet feeding device including: a cassette housing section; a sheet storage cassette; and a sheet feeding unit. The sheet storage cassette includes a cassette base which is configured to store recording media that have a sheet form, and can be inserted into and removed from the cassette housing section. The sheet feeding unit is provided in the cassette housing section, and is configured to feed the recording media to be stored in the sheet storage cassette. A pair of fixed-side rails that are made of metal and are attached to the cassette housing section. The cassette base is made of a resin. A pair of inner rails that are coupled to the pair of fixed-side rails so that the pair of inner rails are slidable are formed integrally with side surfaces of the cassette base.
Claims5
A sheet feeding device, comprising:
- a cassette housing section;
- a sheet storage cassette
- that includes a cassette base that is configured to store recording media that have a sheet form, and
- that can be inserted into and removed from the cassette housing section;
- and
- a sheet feeding unit
- that is provided in the cassette housing section, and
- that is configured to feed the recording media to be stored in the sheet storage cassette,
- a pair of fixed-side rails that are made of metal and are attached to the cassette housing section
- the cassette base being made of a resin,
- a pair of inner rails that are coupled to the pair of fixed-side rails so that the pair of inner rails are slidable being formed integrally with side surfaces of the cassette base,
- wherein the pair of fixed-side rails include
- a pair of outer rails that are fixed to inner side surfaces of the cassette housing section, and
- a pair of middle rails that are coupled to the pair of outer rails so that the pair of middle rails are slidable,
- wherein the pair of inner rails are coupled to the pair of outer rails through intermediation of the pair of middle rails so that the pair of inner rails are slidable,
- wherein the pair of inner rails each include
- a main-body portion that has a flat-plate form and extends in an insertion direction and a removal direction of the sheet storage cassette, and
- a pair of guide ribs that protrude outward along both side edges extending in a longitudinal direction of the main-body portion,
- wherein an at least one reinforcing rib that extends in a vertical direction between the pair of guide ribs is formed in the main-body portion,
- wherein the pair of inner rails each include a retaining member
- that is provided to the main-body portion, and
- that is configured to engage with a corresponding one of the pair of middle rails when the corresponding one of the pair of middle rails is completely drawn out of a corresponding one of the outer rails, thereby to prevent disengagement of the corresponding one of the pair of inner rails from a corresponding one of the pair of fixed-side rails, and
- wherein the at least one reinforcing rib is formed on a downstream side in the insertion direction of the sheet storage cassette relative to the retaining member.
