An automatic document feeder includes original stacker having plural stages spaced from each other, each of which is capable of accommodating sheet originals; a support for supporting the plural stages for movement substantially along the stages; a feeder for feeding sheet originals from a selected one of the stages of the original stacker; conveyer for conveying the sheet originals from the feeder to a predetermined position; reversing device for returning the sheet originals having been placed at the predetermined position to the same selected stage; and a driver for driving the original stacker so as to bring the plural stages selectively toward the feeder.
摘要:
A sheet post-processing apparatus includes stacking device for stacking sheet materials discharged; processing device for processing the sheet materials stacked on the stacking device; discharging device for discharging from the stacking device the sheet materials processed by the processing device when a processing mode is selected; an accommodating device, movable substantially vertically, for accommodating sheet materials discharged by the discharging device; second discharging device for discharging, in the processing mode, the sheet materials so that the sheet materials are bridged between the stacking device and the accommodating device, and for discharging, in a non-processing mode, the sheet materials so that they are stacked on the accommodating device.

An image forming apparatus includes: a supporting tray (70) for supporting cartridges (P), wherein the tray is movable to an outside position (III), a first inside position, and a second inside position; a first positioning portion, provided in a main assembly, for positioning an associated cartridge of the cartridges when the tray is located at the first inside position, and a first preventing portion, provided in the main assembly, for preventing rotation of the associated cartridge about the first positioning portion; and a second positioning portion (70a, 70b), provided to the tray, for positioning the associated cartridge when the tray is located between the outside position and the second inside position. The second positioning portion is in a state in which the second positioning portion is spaced from the associated cartridge, when the tray is located at the first inside position.
