Abstract:
A sheet conveying apparatus, including: a sheet storage portion; a roller to convey sheets by rotating about a rotation axis; an arm rotatably supporting the roller and pivotable about an arm pivot axis; a presser plate pivotable about a presser-plate pivot axis; and a pivot mechanism to pivot the presser plate such that a contact angle, which is an angle defined upstream in a sheet conveyance direction by the arm and an uppermost one of the sheets contacting the roller, is less than a maximum angle in a time period from a sheet maximally loaded state to a sheet minimally loaded state, the maximum angle being an angle defined upstream in the conveyance direction by: only one sheet assumed to be placed on the presser plate which is the presser plate in the maximally loaded state; and the arm the roller of which contacts the one sheet.

Claim (Index 1):
A sheet conveying apparatus, comprising:\n a storage portion for storing a stack of a plurality of sheets; a roller rotatable about a rotation axis parallel to the plurality of sheets stored in the storage portion and configured to convey the plurality of sheets in a conveyance direction by rotating about the rotation axis while being held in contact with a surface of an uppermost one of the plurality of sheets stored in the storage portion; an arm rotatably supporting the roller, the arm being pivotable about an arm pivot axis parallel to the rotation axis with the roller located downstream of the arm pivot axis in the conveyance direction; a presser plate pivotable about a presser-plate pivot axis parallel to the rotation axis and configured to press the plurality of sheets stored in the storage portion toward the roller, the presser-plate pivot axis being located downstream, in the conveyance direction, of the rotation axis of the roller in a maximally loaded state in which a maximal amount of the plurality of sheets are loaded on the storage portion; and a pivot mechanism configured to pivot the presser plate about the presser-plate pivot axis, wherein the pivot mechanism is configured to pivot the presser plate such that a contact angle, which is an angle defined upstream in the conveyance direction by the arm and an uppermost one of the plurality of sheets that is held in contact with the roller, is less than a maximum angle in a time period from the maximally loaded state to a minimally loaded state in which a minimal amount of the plurality of sheets are loaded on the storage portion, the maximum angle being an angle defined upstream in the conveyance direction by: only one sheet assumed to be placed on the presser plate which is the presser plate in the maximally loaded state; and the arm the roller of which contacts the one sheet.
