Problems solved by technology

However, the side guide plate for adjusting the position in the paper width direction is only used for the manual paper tray, that is, it is only provided on the front end side of the paper feeding direction of the stacked long paper, and the side of the auxiliary paper tray is not provided. side guide
[0007] Therefore, the position in the width direction of the rear end side of the paper feeding direction of the long paper cannot be adjusted necessarily, and the stacking state of the long paper on the manual tray and the auxiliary tray is unstable, so there is concern about adjustment errors of the long paper and conveyance failure of long paper with adjustment errors

Embodiment 1

[0039] figure 2 is a schematic diagram showing a first embodiment of the tandem image forming apparatus used as the sheet processing apparatus of the present invention.

[0040] As shown in the figure, in the tandem imaging device, imaging units 22 (specifically 22a to 22d) of four colors (in this embodiment, black, yellow, magenta and cyan) are arranged laterally in the body casing 21, An intermediate transfer belt 23 that is circularly conveyed along the arrangement direction of each image forming unit 22 is provided on the upper portion of the unit 22 . On the other hand, at the lower part of the body case 21, there are provided a predetermined number of stages of paper feeding cassettes 24 in which paper (not shown) is stored, and the paper conveying path extending from the paper feeding cassettes 24 is along the Approximate vertical orientation setting.

[0041] In this embodiment, each image forming unit 22 (22a to 22d) forms toner images in the order of black, yellow...

Embodiment 2

[0063] Figure 6 Shows the second embodiment of the manual paper feeder.

[0064] In the figure, although the basic structure of the manual paper feeding device is approximately the same as that of the first embodiment, they are different in that the auxiliary side guides 74 (fixed side guides 74a, movable side guides 74b ) is movable in the paper transport direction.

[0065] For example, with regard to the supporting structure of the fixed side guide plate 74a of the auxiliary side guide plate 74, the side positions of the fixed side guide plate are fixed, such as Figure 7A As shown, the fixed side guide plate 74a is foldably supported by a support frame 81 which is movable along a transport direction guide slit 82 extending in the paper transport direction, and protrudes from the support frame 81 and forms a predetermined The number of fixing pins is 83. The inner wall of the guide slit 82 in the conveying direction forms a fitting groove 84, wherein the fixing pin 83 i...

Embodiment 3

[0069] Figure 8 Shown is the third embodiment of the manual paper feeder.

[0070] In the figure, although the basic structure of the manual paper feeding device is basically the same as that of the second embodiment, the difference is that there are a plurality of auxiliary side guide plates 74 (fixed side guide plates 74a, fixed side guide plates 74a, The position of the movable side guide 74b).

[0071] That is to say, in the present embodiment, with regard to the supporting structure of the fixed side guide plate 74a of the auxiliary side guide plate 74, the mounting protrusion 91 extending downward is formed at the lower end of the fixed side guide plate 74a, while the paper A plurality of (three in this embodiment) mounting holes 92 (specifically, 92(1) to 92(3)) are formed in the extended paper tray 73 in the conveying direction, and the fixed side guide plate 74 can be arbitrarily Install into any mounting hole 92.

[0072] On the other hand, as far as the support ...

Abstract

A sheet supply apparatus for supplying stacked sheets includes a standard sheet tray provided with a standard side guide that regulates a position in the width direction of the stacked sheet, and an extension sheet tray extendably disposed upstream of the standard sheet tray in a sheet feeding direction, wherein the extension sheet tray has an auxiliary side guide that regulates a position in the width direction of a sheet feeding direction upstream portion of a long sheet. A sheet handling apparatus using the sheet supply apparatus.

Description

technical field [0001] The present invention relates to a paper supply device for supplying paper, and more particularly to improvements in a paper supply device for supplying long paper and a paper processing device using the paper supply device. Background technique [0002] Generally, the sheet processing device is, for example, an electrophotographic type image forming device. [0003] In such a conventional image forming apparatus, an electrophotographic type image forming engine (image forming engine) is installed in the apparatus body, an image is formed by the image forming engine, paper is supplied to the image forming engine from a paper feeding apparatus, and the image formed by the image forming engine is transferred to the image forming engine. printed and fixed onto said paper, and then said paper is output to a paper discharge device. [0004] Here, there are several kinds of paper feeding devices such as a cassette type incorporated in a device body or a man...
