Problems solved by technology

[0007] However, in the paper conveying device having the conventional paper feeding unit 70, there is a problem that, in order to adjust the separating pressure adjusting screw 82, the cork pad 77 must be removed from the locking cover 78, and the operation is cumbersome.
In addition, since the axis of the separation pressure adjustment screw 82 does not coincide with the axis of the coil spring 81, there is also a problem that the separation pressure cannot be adjusted in a stable state.
In addition, in the paper conveying device having other conventional paper feeding assemblies 90, since the internal guide assembly 96 needs to be a rotatable structure, there are problems of complicated mechanism and cost increase.

Embodiment Construction

[0021] Hereinafter, a paper conveying device according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic longitudinal sectional view showing the configuration of an image reading device G including an ADF 1 serving as a sheet conveyance device. The image reading device G is installed on an upper portion of a copier / facsimile multifunction machine or the like, and reads image information of a document to be copied or a document to be transmitted by facsimile. This image reading device G includes: a device main body 4 configured to house a reading unit 2 inside and a platen glass 3 disposed thereon; upper part. When reading a book-shaped original P with a certain thickness, open the original pressure plate 5, place the original P on the platen glass 3, then close the original platen 5, make the original P and the platen glass 3 close contact, in this state Next, the reading unit 2 reads the image of the document w...

Abstract

In a paper transportation device, a separation pressure adjusting screw is provided in a transportation device main body under a separating pad holder. One end of a coil spring makes contact with the separation pressure adjusting screw, and another end of the coil spring makes contact with a position located away from a separating pad in the separating pad holder. A screw adjusting hole is provided on the separating pad holder for adjusting a screwed-in amount of the separation pressure adjusting screw from above.

Description

technical field [0001] The present invention relates to a paper conveying device for conveying the paper set on the paper supply tray to the paper output tray, and in particular to a device for clamping and separating multiple sheets of paper successively sent out from the paper supply tray by using separation rollers and separation pads. separate paper feeder. Background technique [0002] Copiers, facsimiles, scanners, etc. are equipped with an image reading device for reading an image of a document, and an image forming device for recording image data read from a document or image data received by a facsimile on recording paper. Many of these image reading devices and image forming devices are provided with a paper conveying device, which sequentially conveys a plurality of original documents and recording paper set on the paper feeding tray, passes through a predetermined image reading position and an image transfer position, and is discharged. to the output tray. For ...
