Embodiment Construction

[0018] Referring to the accompanying drawings, a stand equipped with a paper release mechanism according to the present invention will be described below.

[0019] figure 1 shows the basic structure of the document reader section of a facsimile machine, etc., and figure 2 Shows how to assemble a stand equipped with a paper release mechanism. In these figures, reference numeral 1 denotes a backing roller made of rubber for feeding and thereby conveying documents P, reference numeral 2 denotes a shaft arranged along the axis of the backing roller 1, and reference numeral 3 Denotes a close contact image sensor (CIS) shaped like a box and elastically supported against the backing roller 1, wherein reference numerals 3a and 3b denote its reading portion and bottom, respectively. The bottom 3b of the close-contact image sensor 3 is elastically supported by springs 5 ​​at two locations so that its reading portion 3a is kept pressed against the outer peripheral surface of the backi...

Abstract

A bracket that rotatably supports a shaft provided along the axis of a back roller for feeding and thereby transporting a document pinched between the back roller and a close-contact-type image sensor elastically supported on a cabinet and that is fitted to the cabinet so as to be rotatable about the shaft is formed integrally with a release lever for releasing the back roller and the close-contact-type image sensor from a state in which they are pressed against each other.

Description

technical field [0001] The present invention relates to a stand equipped with a paper release mechanism used in a document reading section of a facsimile machine or the like, and to a document reading apparatus using such a stand. Background technique [0002] In a facsimile machine or the like using a close-contact image sensor as a document reading device, its document reading section, as disclosed in, for example, Japanese Patent Application Laid-Open No. H8-65446, is structured as follows. In the path through which the document P is conveyed, the backing roller and the image sensor are partially pressed against the document by means of provided springs, so that the image on the document fed by the backing roller is continuously read while the image is kept pressed against the side of the image sensor. read on the surface. [0003] In a document reading section using a pressure contact type image sensor like this, when a document is jammed in a conveyance path, it remain...
