    摘要: The detachment of a feed roller rotatably supported by a holding portion provided in the main body of an apparatus, and held detachably in the axial direction thereof is restricted by a locking device. The locking device is made movable to a lock position and a lock releasing position for permitting the detachment of the feed roller. Further, when the locking device is in the lock releasing position when a sheet stacking portion is mounted, the locking device is moved to the lock position by a position changeover device in operative association with the mounting operation of the sheet stacking portion.

    摘要: Sheets fed out from a sheet feeding portion, which is brought into pressure contact with the sheets by the upward movement of a sheet stacking portion to feed out the sheets, are separated and conveyed one by one while being upwardly curved. During the sheet feeding operation, the sheet stacking portion is sequentially moved up, and when the sheet feeding operation is completed, the sheet stacking portion is moved down. Further, a remaining amount indicating member moved with the upward movement of the sheet stacking portion to indicate the remaining amount of sheets is held at a position before the sheet stacking portion is moved down, by a holding mechanism, when the sheet feeding operation is completed and the sheet stacking portion is moved down.

    摘要: A controller sets a pressure-contact time from memory in accordance with rigidity of a sheet and starts a feeding operation of a sheet by causing a feeding roller to be pressure contacted with sheets on a sheet stacking plate. The controller controls the feeding roller to be separated from the sheets on the sheet stacking plate after passage of the pressure-contact time. In this way, it is possible to set the optimum pressure-contact time at the time of feeding sheets in accordance with the kind of sheet being fed and realize a stable feeding operation. Since the controller controls a driving unit based on a detection signal of a sheet-surface detecting flag that detects the height of the uppermost surface of a sheet bundle, it is possible to realize the stabilization and acceleration of a contacting operation.
