A sheet conveying device includes a tray, a conveyor, and a guide body. The tray is configured to stack a sheet. The conveyor is configured to convey the sheet to the tray. The guide body has a space, a height of the space being greater than a thickness of the sheet. The guide body is configured to guide the sheet conveyed by the conveyor, with a leading end of the sheet being inserted in the space. The guide body is configured to separate the sheet from the space, according to a difference of a sheet conveying speed of the conveyor and a moving speed of the guide body, and to stack the sheet on the tray.

A sheet feeding device includes a sheet stacking unit, a long sheet stacking unit, a first guide, a first detector, and a closing unit. The sheet stacking unit is movable up and down. Sheets are stacked on the sheet stacking unit. The long sheet stacking unit is detachably mounted on the sheet stacking unit. Long sheets are stacked on the long sheet stacking unit. The first guide is movable along a feeding direction through a groove. The first guide is deformable into a shape that does not interfere with the long sheet stacking unit. The first guide guides a rear end portion of the sheets in the feeding direction. The first detector is provided in the first guide. The first detector detects the sheets stacked on the sheet stacking unit. The closing unit is detachably attached to the groove in the sheet stacking unit. The closing unit closes the groove.

A paper sheet processing device includes: an accommodating part that accommodates a paper sheet; and a sliding stage part that is provided within the accommodating part and supports the paper sheet accommodated within the accommodating part, the sliding stage part sliding with respect to the accommodating part to cause a portion of the sliding stage part to protrude to outside of the accommodating part, and the sliding stage part sliding with respect to the accommodating part to push the paper sheet to the outside of the accommodating part and cause a leading end of the paper sheet to protrude to the outside of the accommodating part.

A sheet feeding apparatus includes a stacking portion, a feed member provided above the stacking portion and configured to feed an uppermost sheet among the sheets stacked on the stacking portion, and a trailing-end regulating member movable in the sheet feeding direction and configured to regulate a position of a trailing end of the sheets stacked on the stacking portion in the sheet feeding direction. The trailing-end regulating member includes a support portion configured to support a lower surface of the sheets stacked on the stacking portion. The support portion has a projecting shape in which a center portion of the support portion in a sheet width direction projects upward as compared with end portions of the support portion in the sheet width direction.

In an image-forming apparatus, when a sheet length of a first sheet is shorter than or equal to a predetermined length, a controller supplies power to an electromagnetic clutch to convey the first sheet and a second sheet so that a sheet gap of the second sheet is equivalent to a first gap. When the sheet length of the first sheet is longer than the predetermined length, the controller supplies power to the electromagnetic clutch to successively convey a first number of sheets so that the sheet gap of each of the first number of sheets is equivalent to the first gap. After the first number of sheets has been conveyed, the controller supplies power to the electromagnetic clutch to convey at least one sheet so that the sheet gap of each of the at least one sheet is equivalent to a second gap greater than the first gap.

A medium conveying apparatus includes a medium tray, a feed roller, an upper guide, a movement sensor including an arm movably provided by the fed medium on the upper guide and on an upstream side of the feed roller, to generate a movement amount signal corresponding to a movement amount of the arm, a medium sensor to detect a presence of the medium at a predetermined position of the medium tray, a processor to determine whether a feeding abnormality of the medium has occurred based on the movement amount signal, detect a size of the medium placed on the medium tray based on a detection result by the medium sensor, and stop feeding of the medium by the feed roller when the processor determines that the feeding abnormality of the media has occurred and the detected size of the media is equal to or less than a predetermined size.

An apparatus for diverting and/or folding articles includes an infeed conveyor, an outfeed conveyor, and a diverter. The diverter is a non-contact, fluid emitting diverter, configured to emit a fluid jet to exhibit the diverting force on the impact zone of the article at a side of the article facing away from the outfeed entry. An angle of the average direction of the diverting force of the fluid jet with the outfeed path at the outfeed entry is in the range of 5° to 85°.
