Abstract

In a standby state wherein a document is set in a document tray and can be supplied when needed, when a start signal is not inputted (S21: NO), a controller determines whether a document regulating plate has been operated or not based on a detection output of a document size detector for detecting a position of the document regulating plate (S31), and when the document regulating plate was operated (S31: YES), the controller lowers the document tray by a predetermined amount and stops it (S32). A lowered amount of the document tray can be arbitrarily set by a user through an operator control panel. With a sheet feeding apparatus, an image reading apparatus and an image forming apparatus constituted as described above, even in a state in which the document is set in the document tray, the set state can be easily canceled by operating the document regulating plate.

Description

technical field

[0001] The present invention relates to a paper feeding device which is mounted on an image reading device such as a copying machine and a scanner, or is mounted on an image forming device such as a printer and a facsimile, for sequentially taking out a stack of paper such as a paper containing device. The paper sheets of the placed documents are fed and conveyed to the conveying channel. The present invention also relates to an image reading device and an image forming device provided with the paper feeding device. Background technique

[0002] At present, there is a device that can automatically take out and convey paper sheets from a document one by one, and then sequentially read document images is mounted on an image forming device or the like, so that images can be efficiently read and formed based on the Read an image of an image. At the same time, with the development of digital technology, the speed of reading images from documents, the speed of co...
