An apparatus for stacking discharged sheets on a sheet stacking plate, including a distance sensor disposed above the sheet stacking plate and having a light illumination portion for illuminating the sheet stacking plate and a light receiving portion for receiving reflected light, and a control device for determining the distance between the distance sensor and a sheet stack resting on the sheet stacking plate and for determining a sheet stacking condition of the sheet stacking plate on the basis of the determined distance.

Sheet stacking apparatus

A sheet folding apparatus wherein a set of sheets is fed by a pair of rotatable members, and is folded by nip force between the rotatable members, the improvement residing in that a feeding speed of the sheet set by the rotatable member, is changed in accordance with a thickness of the sheet set.

Sheet folding apparatus

A sheet loading apparatus includes an ejecting unit for ejecting sheets from an image forming apparatus onto a tray, a non-contact distance measuring unit disposed on the tray to measure the distance between the upper surface of the sheet bundle on the tray and a predetermined position, a lifting unit for vertically shifting the tray, and a unit for performing sheet loading abnormality detection on the tray, vertical shift control for the tray, sheet presence/absence detection on the tray, and sheet loading amount detection on the tray in accordance with the distance measuring result of the distance measuring unit.

Sheet loading apparatus having means for measuring distance from sheet

The present invention provides a laminating apparatus including a sheet conveyor for conveying a sheet to be laminated, a film conveyor for conveying an elongated laminate film, a pressurizer for overlapping the sheet and the laminate film and for pressurizing the sheet and the laminate film, a film cutter for cutting the laminate film overlapped with the sheet, a sheet detector for detecting the sheet conveyed by the sheet conveyor, and a controller for controlling the film cutter. The controller is so controlled that the laminate film is cut in registration with the leading and trailing ends of the sheet on the basis of detection by the sheet detector.

Laminating apparatus

An original feeding device for feeding OHP originals to the display stage of an overhead projector is capable of transportation control suitable for OHP projection. The originals are transported by a conveying film onto the display stage. In order to stop the original at the center of the display stage, after the original is detected by the registration sensor, the conveying film is advanced by an amount equal to the sum of the distance from the registration sensor to the display stage, a half of the length of the display stage and a half of the length of the original.

Original feeding device

A projection original film feeding apparatus is provided with a feeder for feeding original film to a projecting position, a sizer for outputting size information of the original film, and a controller for varying the amount of feed the original film by the feeder to conform with the size information from the sizer and setting the original film at a regular projecting position for each size irrespective of the size.

Projection original film feeding apparatus

The present invention provides a laminating apparatus comprising a sheet feeder for feeding a sheet on which an image is formed, a laminate film feeder for feeding laminate films, a heater for heating the laminate films being fed, a device for pressurizing the sheet and the laminate films being fed by the sheet feeder and the laminate film feeder, by overlapping the sheet and the laminate films, a temperature for detecting a temperature of the heater, and a controller means for prohibiting a laminate mode when the temperature detected by the temperature detector is lower than a predetermined set temperature.
