SHEET FEED CASSETTE, SHEET FEEDER, AND IMAGE FORMING APPARATUS

摘要

A sheet feed cassette includes a cassette main body, a sheet loading plate, a regulating member, and an auxiliary member. The sheet loading plate has a support surface and an opening. The support surface supports a sheet sheaf of one or more sheets. The regulating member is slidable within the opening in a sheet width direction perpendicular to a sheet feed direction. The regulating member regulates the sheet sheaf by coming into contact with an edge of the sheaf. The auxiliary member is supported by the sheet loading plate. The auxiliary member is in contact with the regulating member. The auxiliary member is turnable in parallel to the support surface in accompaniment to sliding of the regulating member. The auxiliary member supports a part of the sheet sheaf located over the opening.

主权项

1. A sheet feed cassette comprising:
a cassette main body with an open top end that includes a bottom plate and side walls standing up from the bottom plate and that is configured to store a sheet sheaf of one or more sheets; a sheet loading plate supported in a tiltable manner about an upstream end of the bottom plate in a sheet feed direction and having an opening and a support surface that supports the sheet sheaf; a regulating member that is located on the bottom plate such as to protrude upward from the support surface of the sheet loading plate through the opening of the sheet loading plate, that is configured to be slidable within the opening in a sheet width direction perpendicular to the sheet feed direction, and that regulates the sheet sheaf by coming into contact with an edge of the sheet sheaf in the sheet width direction; and an auxiliary member supported by the sheet loading plate in contact with the regulating member, wherein the auxiliary member is turnable in parallel to the support surface of the sheet loading plate in accompaniment to sliding of the regulating member and supports a part of the sheet sheaf located over the opening.
