Abstract

PURPOSE:To make possible to stack up sheets one by one in the order of conveyance of the sheets, by making the rotational speed of a first pair of rollers lower than that of a second pair of rollers, and by setting the sheet conveying length between the first and second pairs of rollers to a value less than the length of the sheets. CONSTITUTION:Conveyer rollers 7, 14, 17 are coupled to a motor M as a drive source through the intermediary of a belt 23. The second conveyer roller 13 is rotated by means of the meshing of a gear so that its rotational speed V2 is set with respected to the rotational speed V1 of the first roller 7 to have such a relationship as V2>V1. After the sheet 2 being led into the space between guide members 5, 6 and then being clamped and conveyed by the first pair of rollers 7, 9, when the leading end of the sheet is led by a guide member 11 to be introduced into between the second pair of rollers 13, 15, the trailing end of the sheet is wound of the first conveyer roller 7 and therefore, the sheet is curled in an upward projecting convex shape due to the above-mentioned sheep relationship V2>V1. With this arrangement the sheets are discharged through between the discharge rollers 17, 19 and stacked one by one onto a loading tray 3.

BACKGROUND ART Generally, a heated roller type fixing device is used in a copying machine from the viewpoint of efficiency, image quality, fixing performance, etc. The output paper that passes through this type of fixing device is subject to heat treatment and is therefore prone to curling. Moreover, this curl varies depending on the environmental conditions during fixing, the type of sheet, the image pattern, etc., and it has been difficult to create a fixing device that does not cause curl.

←Q Problems to be solved by the invention Sheets output from a heated roller type fixing device tend to curl, so they cannot be stacked properly on a tray. In particular, if the rear end of the sheet is curled and raised, the leading edge of the newly outputted sheet)2 on the tray 3 with the rear end raised is Because it comes into contact with the paper and crawls under it, it is difficult to stack it on the top shelf.

Means for Solving the Problems The present invention aims to solve the above-mentioned problems, and includes a sheet conveying path consisting of a combination of a plurality of roller pairs and a guide member, and a sheet conveying path consisting of a combination of a plurality of roller pairs and a guide member, and a sheet conveying path formed from sheet 1 to the exit of the conveying path. Sheet stacking device consisting of sheet trays - 1 - A first pair of rollers on the amateur side and a second pair of rollers located at the next stage and conveying in a direction different from the conveying direction of the first pair of rollers. Further, the length of the sheet feeding path between the first roller pair and the second roller pair is set smaller than the length of the sheet S), and the rotational speed of the first roller pair is set smaller than that of the second roller pair. As the sheet is conveyed by the second pair of rollers, tension acts between the first pair of rollers and the second pair of rollers, and the sheet is conveyed by the first pair of rollers. It is characterized by its ability to wrap around itself.

(E) Operation Based on the above-mentioned means, the sheet is held between the first pair of rollers on the entry side,
The sheets to be conveyed are guided to the sheet 1-15 feed path formed by a pair of downwardly inclined conveyance guide members, and the rice is
When the -1 to rear end portions are being held by the 10th sheet carry-in side pair, the first sheet J1 reaches the second pair of rollers at the next stage and is held there. Since the rotational speed of the second roller pair is faster than that of the first roller pair, tension is applied to the sheet, and the rear end of the sheet 1 is curled in the shape of a vertical convex portion before exiting the first roller pair. Therefore, sheets whose rear ends are curled into an upwardly convex shape are stacked one after another on the sheet lay.
