摘要： The present invention relates a sheet feeding apparatus with a lifting and lowering mechanism in a sheet deck 2, which includes abutting portions 101a to 101d which makes wire hanging portions 64a to 64d of a sheet stacking table 52 abut thereon and makes the sheet stacking table 52 lockable with respect to a storing portion 61. The mechanism also includes a pulse motor 27 and a one-way clutch 40. A controller 5 drives the pulse motor 27 to be rotated in a lifting direction of the sheet stacking table 52, further drives the pulse motor 27 to be rotated in the same direction even after the wire hanging portions 64a to 64d abut on the abutting portions 101a to 101d to cause the pulse motor 27 to step out, and renders the pulse motor 27 non-conductive. Thus, the wire hanging portions is locked to abut on the abutting portions.

摘要： When a retard roller is rotating in a sheet feeding direction, the rotation is transmitted to a pickup roller and the pickup roller rotates in a direction for conveying the sheet. When the retard roller is rotating in a direction opposite to the sheet feeding direction or is stationary, the pickup roller does not feed the sheet. Therefore, in a successive feeding operation, the sheet to be fed next is always conveyed such that the leading end thereof reaches a nip position between a feed roller and the retard roller. Therefore, the intervals between the sheets are uniform in the successive feeding operation.

摘要： A sheet feeding apparatus, in which a drive motor rotates a pickup roller, and a drive transmission portion provided between the drive motor and the pickup roller transmits a drive from the drive motor to the pickup roller. During sheet feeding, one of the drive motor and the drive transmission portion causes the pickup roller to perform an intermittent drive of iterating the drive and a stop, so that a sheet is gradually deflected between the pickup roller and separation claws.
