Problems solved by technology

[0005] However, when the user sets the document bundle on the document loading tray, there is a problem that the conveying unit arranged at the standby position will drop due to the operation of aligning the ends of the document bundle with the stopper.
As a result, the paper feed unit is lowered from the standby position, and the stopper set to face the fixed state becomes the unfixed state, so the front end of the document bundle reaches the vicinity of the platen part (document separation part) of the conveying roller pair and occurs. Problems such as overlapping feeding of originals (multi-feeding) or skewing

Embodiment Construction

[0020] Hereinafter, embodiments of the present invention will be described with reference to the drawings. figure 1 It is a schematic configuration diagram of an image forming apparatus 100 equipped with a document conveyance device 27 of the present invention. exist figure 1 In the image forming apparatus 100 (here, a multifunction peripheral is shown as an example), when performing a copying operation, image data of a document is read by the image reading apparatus 6 and converted into an image signal. On the other hand, in the image forming unit 3 in the main body 2 of the multifunction peripheral, in figure 1 The photosensitive drum 5 rotating in the A direction is uniformly charged by the charging unit 4 . And, an electrostatic latent image is formed on the photosensitive drum 5 by a laser beam from an exposure unit (laser scanning unit or the like) 7 based on original image data read by the image reading device 6 . Thereafter, a developer (hereinafter referred to as t...

Abstract

The invention provides a document conveying device and an image forming apparatus. In a document conveying device, a stopper is configured to be changeable between a position where a document restriction portion is vertically hung down and opposed to the front end of document sheets on the document stacking tray and a released position where document restriction portion is released from the front end of the document sheets. The restriction surface extends downward from a position coinciding with a first trajectory toward an inner side of the first trajectory when the stopper swings about a stopper fulcrum. According to the invention, overlapping and inclined conveying of document sheets can be prevented when the front end of document sheets is sent next to a document sheet separation portion.

Description

technical field [0001] The present invention relates to a document conveying device that is mounted on an image forming apparatus such as a digital copier or a laser printer, and that feeds paper by separating a document from a document bundle one by one, and an image forming apparatus including the document conveying device. Background technique [0002] Conventionally, in an image reading device mounted on a copier or the like using electrophotographic processing, sheet-shaped originals are sequentially fed into the original table for reading and ejected from the original table after reading. Image reading device for automatic document feeder. In such an image reading apparatus, it is possible to adopt a sheet through method in which a document is automatically conveyed by the document conveyance device for reading while the document presser is closed, and the document presser is opened and closed every time the document is read. There are two reading methods, the documen...
