Embodiment Construction

[0025] Hereinafter, a typical embodiment of the sheet feeding device according to the present invention will be explained with reference to the drawings. However, the present invention is not limited to the embodiments described below. Although the sheet feeding device according to the present invention is provided to an image scanner, for example, the sheet feeding device may also be provided to an image copying machine or the like.

[0026] Next, the sheet feeding device according to the first embodiment of the present invention will be explained. figure 1 It is a typical cross-sectional view of the outline of the sheet feeding device according to the first embodiment.

[0027] The sheet feeding device 10 includes: a tray 12, a conveying roller 14, a separation roller 16 as a separation unit, a motor 18 as a rotation drive unit, a pair of conveying rollers 20, a pair of detection sensors 22, and a control circuit as a control unit twenty four.

Abstract

The invention relates to a sheet feeding device. Imaging target media stacked in a tray are bent in a width direction orthogonal to a transmission direction so that rigidity of the imaging target media in the transmission direction increases than the rigidity before bending. Consequently, even though a separation imaging-target medium is bound together with a transportation imaging-target medium using a binding member, the separation imaging-target medium is transmitted to an imaging unit along with the transportation imaging-target medium by transporting rollers without bending in the transmission direction. A superimposed-transmission of the imaging target media is detected by sensors and rotation of the transmitting roller is stopped. So, the superimposed-transmission of the imaging target media is stopped just before the imaging unit.

Description

Technical field [0001] The present invention relates to a sheet feeding device that conveys a sheet-like imaging target medium to an imaging unit provided in an image scanner or an image copying machine. Background technique [0002] A sheet feeding device, in other words, a so-called automatic document feeder (ADF), feeds originals (sheet-shaped imaging target media) one by one to an image forming unit provided in an image scanner or image copying machine. [0003] In such a sheet feeding device, due to the rotation of the conveying roller, among the originals stacked in the tray, the conveyed originals in contact with the conveying roller are sequentially conveyed to the image forming unit. When the separated originals are stacked on the conveyed originals, the separation unit such as the separation roller comes into contact with the separated originals, and the separated originals are separated from the conveyed originals by moving the separated originals in the opposite direc...
