Paper feeding device

Abstract

In order to more reliably minimize the occurrence of defective feeding of an original document (S), a paper feeding device (5) is provided with an original document loading stand (10) on which an original document (S) is loaded and a feed mechanism (30) that feeds the original document (S) loaded on the original document loading stand (10) downstream in the feed direction of the original document (S). An edge section of the original document loading stand (10) on the downstream side in the feed direction of the original document (S) in the feed mechanism (30) is connected to a scanner main body (2) so as to be capable of rotating around a first rotational axis (21) that is parallel to the rotational axis (33) of a pick roller (31). The first rotational axis (21) is positioned on the downstream side of the feed mechanism (30) in the feed direction of the original document (S) in the feed mechanism (30). When the original document (S) is loaded on the original document loading stand (10), a loading surface (15) for the original document (S) on the original document loading stand (10) is positioned above the pick roller (31). When feeding the original document (S) that is loaded on the original document loading stand (10), the loading surface (15) of the original document loading stand (10) rotates around the first rotational axis (21) so as to move downward. As a result, the loading surface (15) is retracted farther downward than a contact section (32) for the original document (S) on the pick roller (31).

Description

technical field [0001] The invention relates to a paper feeding device. Background technique [0002] An image reading device that reads a document image and performs electrical processing or a printing device that performs image printing is often provided with a paper feeding device to supply a sheet such as a document to be read or a sheet of paper to be printed to the image reading unit or the printing section side. The paper feeding device feeds paper to the downstream side by rotating a pickup roller having a relatively high coefficient of friction in contact with the document. Because the pickup roller uses the friction between the original and the original to feed the paper to the downstream side, in the existing paper feeding device, in order to perform appropriate paper feeding, it is sometimes necessary to adjust the contact state between the original and the pickup roller ( For example, refer to Patent Documents 1 and 2).

AI Technical Summary

Problems solved by technology

[0005] However, even if the original is properly in contact with the pickup roller during paper feeding, if it is not properly set on the original placement table, when the paper is fed by the pickup roller, there may be problems due to the fact that the original is not in contact with the pickup roller. As a result, the manuscript cannot be provided to the downstream side, etc.
