Description

[Detailed description of the invention]

The present invention relates to an automatic paper feeder for a copying machine. A conventional paper feeding device that uses roll paper and is configured to automatically cut the roll paper into a predetermined length and use it as copy paper is as shown in the schematic layout diagram in Figure 1. In the omitted frame, Freno installed on the left,
The roll paper 3 attached to the support 2 of the cover 1 is sandwiched between a drive roller 4 and a flexible roller 25 provided on the right side, and a cutter unit consisting of a fixed cutter 6 and a rotary cutter 7 located on the right side. 8, the sheet is conveyed between a pair of upper and lower baffles 9 and 9' on the sheet conveyance path, and the rotary cutter 7 is rotated to cut the sheet at a predetermined position. There is. Therefore, in order to use this device for copying a new roll paper or a different type of roll paper, the leading edge of the roll paper 3 must also be trimmed just before the cutter part 8. To do this, as shown in Figure 282, the operator 1+:t7 grasps the handle 10 of the frame cover 1 and moves it to the left using the shaft 11 of the cover 1 as a fulcrum. , attach the roll paper 3 to the support 2, sandwich its tip between the drive roller 4 and the flexible roller 5, and turn the cutter part 8 with your left hand.
As the paper is fed out, the right hand is attached to the Zoyaft 2, which is installed in front of the upper baffle of the pair of upper and lower baffles 919' in the paper conveyance path. is the retaining part 1 engaged with one end of the fixed cutter 6
3. Grasp the paper regulating claw plate 14 and hold it upward.
When the leading end of the roll paper 3 passes through the cutter part 8, it is guided upwards using the curl of the paper and guided out of the machine, and the rotary cutter 7 is rotated to cut it. Then, when the leading edge of the roll paper 3 is positioned just in front of the cutter part 80, K. One method was to remove the excess portion and close the frame cover 1 and paper regulating claw plate 14 again. However, with this method, the operator 61 has both hands occupied, and the roll paper 3 is not curled well, and the leading edge of the roll paper 3 passes through the cutter part 8 and is ejected upward. In some cases, the paper goes straight without coming and ends up between the baffles 9 and 9' of the paper conveyance path, or it is ejected above the cutter part 8 but is ejected obliquely. If the problem occurs, there is a drawback that this cannot be corrected, and the paper may be stuck in the baffle 9, 9' when copying due to forgetting to close the paper regulating claw plate 14 or closing it incompletely. The roll of the conventional copying machine described above has the disadvantage that the roll of the copying machine is caused to advance toward the upper blade of part 8 of the cutter instead of toward the direction of 9', causing a paper jam or the like and causing a light to blow. This was made in order to eliminate the drawbacks of paper feeding devices, and includes the paper regulating claw plate 14 that engages with the fixed cutter 6 and closes the upper part of the cutter part 8, and the frame cover and gift 12. A link mechanism is provided between the shaft 11 of 1 and the shaft 11 so that the two can be linked together. When the frame cover 1 is closed, the paper regulating claw plate 14 closes the upper part of the cutter part 8, and the paper 3 is conveyed automatically. The baffle 9 of the path moves in the direction between (]', so that it is easy and quick to complete the cenotening for the roll-off ((copy of σ)), and it is possible to forget to close the P for Vl and the regulating claw plate 14. An object of the present invention is to provide an automatic paper feeder for a 11-1 copying machine, which eliminates paper jams and the like caused by incomplete closing. Detailed explanation based on drawings,
