Abstract

A sheet loading device is provided with a sheet ejection portion, a sheet loading portion, a first detection mechanism, a driving device, a second detection mechanism, and a control portion. The driving device drives the sheet loading portion to ascend / descend between an upper surface detection position and a reference position made to descend by a prescribed distance from the upper surface detection position. The second detection mechanism detects that the sheet loading portion is at the reference position. In a case where sheets of the same type are ejected continuously from the sheet ejection portion, the control portion controls beforehand the sheet loading portion to ascend from the reference position to the upper surface detection position and sets a loadable number of sheets of the sheet loading portion in accordance with an ascending time of the sheet loading portion.

Description

technical field [0001] The present invention relates to a sheet material post-processing device used in image forming apparatuses such as copiers, facsimile machines, and printers, and for performing post-processing such as punching processing or stapling processing on sheets such as paper after image formation by the image forming apparatuses. A sheet loading device, and a sheet post-processing device and an image forming apparatus having the sheet loading device. Background technique [0002] An electrophotographic image forming apparatus forms an electrostatic latent image by irradiating light based on image information read from a document image or image information transmitted from an external device such as a computer onto the peripheral surface of an image carrier (photosensitive drum). After supplying toner to the electrostatic latent image from a developing device to form a toner image, the toner image is transferred to paper. The transfer-processed paper is discha...
