のシート矯正搬送装置に関するものである。[Detailed Description of the Invention] The present invention relates to copying machines, printing machines, recording machines, and other various machines equipped with a mechanism for conveying sheets (hereinafter referred to as copying machines, etc.).
The present invention relates to a sheet straightening and conveying device.

いたものであった。Conventionally, in KonoMori's equipment, in order to remove curls, etc. of sheets that occur inside the equipment when ejecting sheets to the outside of the equipment, a lower paper ejection roller 1 and a lower paper ejection roller 1 are used as shown in FIG. By feeding the sheet 4 in a wavy shape as shown in the figure by the integrated flange portion 6 with a slightly larger diameter and the upper paper discharge roller 2, the apparent rigidity of the sheet is increased and curling is performed, and the sheet is placed on a paper discharge tray, etc. Loading sheets. However, in case of double-sided recording or large-volume recording, the recording-processed sheet is not ejected to a paper output tray, etc., but the sheet is changed direction and conveyed to the recording processing section again for re-recording. In this case, the sheet is given an apparent rigidity using the above-mentioned paper ejection roller, etc.5, and when the sheet is changed direction, it is not smoothly conveyed to the re-recording conveyance path, and the sheet is not smoothly conveyed to the re-recording conveyance path. This may cause paper jams to occur. Therefore, in such cases, provide a flange on the ejection roller for transporting the paper to the outside of the device, and (1) provide a separate transport path within the device for transporting the paper. It is possible to use a flangless type, but if the sheet is directly conveyed from the sheet ejection section into the device, that is, the sheet ejection roller 6 is used for both purposes, each sheet ejection roller may be flanged. It had the disadvantage that it was inconvenient for non-wealthy people to have to exchange it for one without fludge.
そこで、本発明はこれらの欠点に鑑みて改良した新規な
シート矯正搬送装置を提供することを目することなく２

ることである。Therefore, the present invention has been made without aiming to provide a novel sheet straightening and conveying device that is improved in view of these drawbacks.
An object of the present invention is to provide a sheet correction conveyance device that allows selection of two conveyance functions.

置である。That is, the main feature of the present invention that can achieve the above object is a conveyance device having conveyance rollers for conveying a sheet to be conveyed, and a plurality of rollers disposed in contact with each other on the upper and lower sides to grip and convey the sheet. a pair of rollers, and a cover member in which a sheet guide portion for guiding the sheet is formed and is removable from the vicinity of the roller pair, and the guide surface of the sheet guide portion is located between the plurality of roller pairs. By being disposed above or below the upper and lower roller nip portions, the sheet conveyed by the pair of rollers is guided along a cross-sectional wave pattern and conveyed straightly. This is a sheet straightening and conveying device characterized by the following features.

FIG. 2 is a cross-sectional view and a plan view showing lJ. In the figure, reference numeral 8 indicates a paper ejection cover that is detachably or rotatably provided on the main body of the apparatus;
Reference numeral 1 denotes a lower paper discharge roller without a fludge, 92 an upper paper discharge roller, and 10 a sheet conveyance path formed by conveyance guides 111 and 1111.

せない通常の搬送ができるようになるものである。A part 81 of the paper ejection cover 8 has the role of further guiding the sheets guided from the sheet conveyance path 10, and as shown in FIG. The uppermost part 81 of the paper ejection cover 8 is located.In addition, when the paper ejection cover 8 is arranged extending downward from the upper side opposite to that shown in FIG. 2, the paper ejection guided by the sheet is A part of the cover 8 is at the bottom.In this way, the paper ejection upper and lower opening rollers 91 @ 9s @ 91'll
The nip 9s e 9g' of 9st / and the part 81 that guides the sheet of the tJL paper cover 8 are separated. ■Since a wavy shaped sheet conveyance path that goes up and down alternately is formed, the sheet being conveyed has apparent rigidity. Also, this paper ejection cover 8 has upper and lower paper ejection rollers 91, 9m, 91', 9! 'When the paper ejection cover 8, which is configured to be detachable or rotatable from the vicinity, is removed, the upper and lower paper ejection rollers 91-9s, 91/, 9s/
This allows normal conveyance without forming a wave-like shape on the sheet, that is, without imparting sheet rigidity.
