An article supporter for a supply device includes a feeder that supplies, by air suction, an uppermost thinly tabular article from a bundle of a plurality of thinly tabular articles that is stacked and is partially different in thickness, the article supporter for supporting the bundle with a gap between the uppermost thinly tabular article and the feeder, and the article supporter includes: a first support that supports respective thinner parts of the plurality of thinly tabular articles; a second support that supports respective thicker parts of the plurality of thinly tabular articles and is movable upward and downward; and an adjuster that adjusts a level of the second support such that the uppermost thinly tabular article of the bundle is set within a predetermined range in a vertical direction.

An apparatus and method for stretch wrapping of a palletized load uses film tension feedback derived from a film tension control load cell to control film dispensation. The load cell measures film tension and the film payout rates is determined by the film tension. Film tension values are used to determine when an out of bounds condition occurs, namely, when a film break has occurred, or when a possible film break is about to occur or when the film has been cut at the end of a wrapping cycle. To prevent film free end entanglement caused by a break, clamps engage the film so the film tail is controlled, eliminating the risk of recoil. The broken film tail may then be quickly and reliably reattached to the rotating load in a desired position.

A paper sheet storage container capable of accurately taking out paper sheets one-by-one. A paper sheet group is held by a paper sheet placing table and holding members, while the paper sheet placing table is being biased upward by an elastic member so that the position of an uppermost paper sheet of the paper sheet group placed on the paper sheet placing table is substantially the same position as the positions of holes through which air flows. In this state, in the paper sheet storage container, air is blown from a side to the uppermost paper sheet of the paper sheet group placed on the paper sheet placing table thereby allowing the uppermost paper sheet to be brought into a state in which the vicinity of the center thereof has been raised.

An image forming apparatus includes an image forming portion, a tray rotatably provided on a side surface of a main assembly and including a stacking surface, a feeding portion; and a blowing fan mounted on the tray and generating air blown to a side end of a sheet in a sheet widthwise direction perpendicular to a feeding direction of the sheet by the feeding portion. The blowing fan is disposed on an opposite side to a side where the sheet is stacked on the stacking surface so that a position of at least a part of the blowing fan with respect to the sheet widthwise direction is overlapped with a position of the stacking surface with respect to the sheet widthwise direction.
