A sheet conveying device includes a conveyor, a supporting section which supports a sheet to be fed to the conveyor and a guide section which is provided on the supporting section and configured to guide a sheet to the conveyor. The supporting section includes a first support region and a second support region which support a sheet. The first support region is provided at a position on an upstream side from the second support region in a sheet conveyance direction. The first support region extends substantially horizontally, and the second support region is inclined in a lower direction toward the downstream side in the conveyance direction. The guide section includes a first portion which extends substantially horizontally along the first support region, and a second portion which is connected to the first portion and extends obliquely in the lower direction along the second support region.

A medium feeder includes a medium mounter, a pair of edge guides, and a sheet number limiter. The medium mounter has a mounting surface on which a medium to be fed is placed. The pair of edge guides is provided at the medium mounter to guide side edges of the medium in a direction that intersects with a feeding direction in which the medium is fed. The sheet number limiter is provided at the pair of edge guides to limit the number of media mountable on the medium mounter. The sheet number limiter has an extension that extends in a feeding direction of the medium such that a distance between the extension and the mounting surface increases downstream.

A sheet feeding apparatus has a conveying roller, a separation member which presses against the conveying roller to form a separation nip portion that separates received sheets one by one, a feeding member configured to feed a sheet towards the separation nip portion, a nip guide member having a first guide portion configured to contact with a leading edge of the sheet fed by the feeding member and a second guide portion disposed at facing position to the conveying roller and configured to guide the sheet abutted with the first guide portion for the separation nip portion and a biasing member configured to bias the nip guide member. The nip guide member rotates around a rotation shaft and the second guide portion is disposed at predetermined distance from the conveying roller and moves in a direction of separating from the conveying roller against biasing force by the biasing member.

A method and an apparatus for holding down a sheet on a feed table of a sheet-processing machine include a lowerable smoothing bar which can be driven according to a speed profile in time with the sheet-processing machine, which results in a targeted deflection of the smoothing bar. The deflection is preserved for the purpose of smoothing the sheet from the middle to the side.

To reduce, at the time of sheet replenishment, breakage of a floating regulation member that regulates floating of a sheet floated by air blowing in a sheet storage apparatus that loosen stored sheets by means of air blowing. Air is blown to sheets stored in a storage part to loosen the sheets. One of a pair of side regulation members for regulating both ends of the sheets stored in the storage part has a floating regulation member for regulating floating of a sheet floated by means of air blowing. The floating regulation member is configured to be turnable in a sheet stacking direction about a rotation axis provided to one of the side regulation members on the side at which the floating regulation member is provided. A load applied to the floating regulation member differs between when the floating regulation member is turned upward and when it is turned downward.

According to the present disclosure, a first guide unit is provided with a first opening portion through which light in an optical path connecting a first optical element unit and a second optical element unit passes, a second guide unit is provided with a second opening portion through which light in the optical path connecting the first optical element unit and the second optical element unit passes, the first guide unit is provided with a duct for sending air to the first optical element unit, and the air coming out from the first opening portion hits the second optical element unit via the second opening portion.

An image forming apparatus includes an apparatus body that forms an image on a recording material; a drawn-out unit that is provided so as to be drawable from the apparatus body and has a mount region on which the recording material is mounted; and a guide unit that is provided on the drawn-out unit and guides the recording material to a position where the recording material is to be mounted on the mount region. The guide unit has a guide surface that guides an end of the recording material, a hook part that is hooked onto the drawn-out unit and determines a position relative to the drawn-out unit, and a release part that releases the hook part from the drawn-out unit by being operated by a user from a guide surface side.
