Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a splicing device for connecting the trailing edge of a continuous sheet of paper to the leading edge of a sheet of the next set of sheets.

FIG. 1 shows a schematic diagram of the electrophotographic printing apparatus up to the transfer process. The continuous paper 1 is fed by a tract 2 at the same speed as the photosensitive drum 3, and the image on the photosensitive drum 3 is transferred onto the paper 1 by a transfer device 4. The end of the continuous paper 1 is detected by the EOF detector 5, and based on the data output conditions, the continuous paper 1 is placed at the position of the transfer device 4.
When the perforation comes, paper feeding stops with paper 1 remaining in front of the lower tractor 2 for paper splicing. Since paper lengths range from 6 inches to 14 inches, the end position when the paper stops moves by about 10 inches depending on the type of paper 1. Since the splice table 6 is fixed, in some cases, the paper 1 may sag by about 10 inches during splicing. Therefore, there is a problem that splicing the paper 1 is difficult. This is especially noticeable with thick paper such as 135Kg paper.

The purpose of the present invention is to eliminate the above-mentioned drawbacks of the prior art and to enable splicing work with good operability.

The present invention is devised so that the splice table can be moved according to the paper length.

An embodiment of the present invention will be described with reference to the drawings. FIG. 2 shows a schematic diagram of the embodiment. The same parts as in FIG. 1 are denoted by the same reference numerals and their functions are the same as in the prior art. splice table 7 is attached to the frame
has been fixed through. Therefore, the improved splice table 7 can be moved arbitrarily to the left in the figure as shown by the broken line (however, the maximum movement distance is approximately 10
inches). Therefore, by moving the splice table 7 to the end position of the paper according to the paper length and aligning the splice position, the slack of the paper 1 is eliminated. This improves splicing workability. When printing and changing paper, the splice table 7 is kept at the position indicated by the solid line in the figure, that is, at the far right side, so that it does not interfere with paper feeding and paper changing operations.

In the present invention, the splice table 7 is moved manually, but if this is changed to a powered type and moved automatically, the operability will be further improved. In particular, since the paper end stop position is determined by the paper length, the movement of the splice table can be completely automated.

According to the present invention, since the splice table is made movable, it is possible to perform splicing operations equally on various paper lengths, thereby improving splicing efficiency.

Claims (1)

[Claims for Utility Model Registration] A splice device that is installed in the running path of continuous paper and connects the trailing edge of the paper and the front edge of the paper of the next set of paper, which connects the trailing edge of the paper and the front edge of the paper. A splicing device is provided with a splicing table which is slidable in a direction perpendicular to the running direction of the paper.
