Abstract

The invention relates to a sheet conveyance device, an image reading apparatus and an image forming device. The trailing-edge detector (M1) includes a rotary follower such as a detection roller (141) and the like and a rotation detector to detect rotation of the rotary follower to detect the tail end of the material sheet, and the detection roller follows the material sheet. The rotation detector consists of an encoder wheel 143, a photosensor 144, a controller, and the like. Compared with comparative sheet conveyance devices in which a photosensor is used as a trailing end detector (M1), passage of the trailing end of the sheet at the trailing-edge detector can be detected promptly. Therefore, the reference length-exceeding distance between original document sheets can be checked. A sheet conveyance device, an image reading apparatus and an image forming device are provided, wherein the intervals between the reference length sheets can be reduced through the sheet conveyance device, and intervals between the specific size sheets can be reduced through the sheet conveyance device.

Description

technical field [0001] The present invention relates to an image reading device of a pass-reading method for sequentially reading images of document sheets being conveyed, and an image forming device for forming images on recording sheets being conveyed. Also, a sheet conveying device used in the above image reading device or image forming device. Background technique [0002] In this type of image reading device, while continuously feeding the original sheets one by one from the original loading section, while sequentially reading the images of the original sheets, and performing continuous reading operations, in order to shorten the reading time, it is desirable to Shorten the distance between sheets. In addition, in the image forming apparatus, images are sequentially formed on the above-mentioned recording sheets while continuously sending out the recording sheets one by one from the recording sheet loading section, and continuous printing is performed. distance betwee...
