The rotation of a lifting and lowering plateis controlled such that, in a case where the height of the sheet loaded in a manual feed trayis maximum, a feed rollerabuts the sheet at a first abutment position at a first moving velocity slower than a second moving velocity at a position upstream in the movement direction of the feed rollerfrom the first abutment position, and, in a case where the height of the sheet loaded in the manual feed trayis minimum, the feed rollerabuts the sheet at a second abutment position at a third moving velocity slower than the first moving velocity at the first abutment position.

Sheet feeding apparatus, image forming apparatus, and image reading apparatus

An electronic apparatus includes a first electronic device, a second electronic device, a bundled wire configured to supply at least one of an electric signal and electric power between the first and the second electronic devices, a frame member, a bundled wire guide, and a plurality of holding portions disposed at different positions on the wiring path. Each of the plurality of the holding portions includes a hinge portion connected to an upper portion of one of the pair of the side wall portions, a cover portion connected to the storage portion via the hinge portion, and an engagement portion to secure the cover portion in a closed position. The frame member includes a groove portion to which the bundled wire guide is fitted, and the bundled wire guide with the bundled wire stored is fitted into the groove portion.

Electronic apparatus, image forming apparatus, and method for producing electronic apparatus

A sheet feeding apparatus includes a sheet stacking portion on which sheets are stacked in a storage unit; a lifting and lowering unit configured to move the sheet stacking portion between a first position and a second position above the first position; and a control unit configured to execute a first mode of waiting for start of feeding processing in a state in which the sheet stacking portion is at the first position and a second mode of waiting for start of the feeding processing in a state in which the sheet stacking portion is held at the second position by the lifting and lowering unit. The control unit executes the first mode when sheets of a first amount are stacked and execute the second mode when sheets of a second amount less than the first amount are stacked.

Sheet feeding apparatus and image forming apparatus

A separation roller for a sheet feeding apparatus includes an outer circumferential portion formed from an elastic material, a core portion to which the outer circumferential portion is attached; and a flange portion including a plurality of projecting portions each projecting to an outside in a radial direction with respect to the core portion. At least one of the plurality of projecting portions includes a first surface provided on a side portion thereof on an upstream side in a first direction in which the separation roller rotates in such a manner as to follow the rotary feeding member rotating to feed the sheet. The first surface extends more upstream in the first direction at a position further on an outside in a radial direction with respect to a rotation axis of the separation roller as viewed in the axial direction.

Separation roller, sheet feeding apparatus, and image forming apparatus

A sheet feeding apparatus includes a sheet supporting portion including a supporting surface, an abutment portion against which a leading edge of the sheet abuts, a feeding rotator configured to feed the sheet, and a first friction member provided on the supporting surface so as to face the feeding rotator. The first friction member includes a first friction surface having a static friction coefficient greater than that of the supporting surface, a trailing end supporting portion configured to support a trailing end portion of the sheet curved upward, and a second friction member disposed upstream of the first friction member in the sheet feeding direction on the supporting surface. The second friction member includes a second friction surface which has a static friction coefficient greater than that of the supporting surface and is configured to be in contact with the sheet supported by the supporting surface.
