Abstract

PURPOSE:To provide a paper cutter which is capable of normally cutting a paper at a border line between pages without moving of a cutter corresponding to a page length of a paper, by mounting a transfer charger which detects that a border line between a pages of a continuous printing paper to be cut passes through a reference position of a paper running. CONSTITUTION:When a border line between a pages to be cut reaches a transfer charger 4 serving a reference position of a paper running after a printing of one job is completed, a counter 14 starts to count the running distance of a paper. If the running distance of the paper matches a distance (d) between the transfer charger 4 and a cutter 7, the counter 14 brings a feed roller 8 to a stop through the working of a flip flop 16, a driver 17 and a clutch-brake 10, and further causes operating of the cutter 7 through the working of the flip flop 16 and a driver 18.

Conventionally, when cutting continuous printing paper printed on a page printer such as an electrophotographic method into zips at page boundaries, the running of the continuous printing paper was not controlled line by line as in line printers, but based on standard control. If you fix the rounding and cutting position, which is controlled on a page-by-page basis,
Except for certain types of paper where the paper length multiplied by the page length matches the distance from the paper travel reference position to the cutting position, cutting will not cause distortion at the page boundary, and the paper length will vary depending on the page length of the paper used. It was necessary to move the cutter.

In this case, since paper with a page length of 7 to 14 inches is used frequently every week, the cutter must be moved by several G millimeters, which requires a lot of adjustment and requires a large device. Moreover, there was a drawback that the mechanism of the paper transport system was complicated.

The present invention has been made in view of the above-mentioned drawbacks, and further includes disposing a stopping means for stopping the running of the continuous tone 11 in the vicinity of the cutting means for cutting continuous printing paper at page boundaries for each job. Page border S of continuous printing paper to be cut
After passing through the reference position for paper running, the cutting means is configured with a run I that calculates the number of stitches of the paper, which corresponds to the length of the paper from the crease base position to the cutting position, and the cutting means and the cutting means are By driving the stop means and cutting the printing paper with a slack of 11 kK before the stop means 0, the page border can always be set without moving the cutter according to the page length of the paper. The purpose of the present invention is to provide a paper cutting device for a nine-page printer that enables paper cutting.

In the figure, 1#i photosensitive drum, ! 3 is a paper feed tractor, 3 is a fixing roller, and 4 is a transfer charger located at a reference position for paper travel. 5 is a continuous printing paper (hereinafter simply referred to as paper), and 6 is a guide plate that forms a mountain shape at the top and quickly makes the paper slack 5a+ into a stable shape when the paper slack 5m occurs. Reference numeral 7 denotes a cutter made of a sharp blade for cutting the paper container, and the transfer charger 4 is also placed at a distance d. A feed roller 8 is paired with the idler 9 and reliably feeds the paper 5 into the cup 77. The feed roller 8 is connected to a drive 11 (not shown) via a clutch/brake 10, a pulley 11, and a belt 12. It is slightly faster than the running speed. This is an exit roller that discharges 9 sheets of paper that have been cut by 13 Fi.

At the 14u counter, the boundary between the 50 pages of paper to be cut is the transfer charger 4Kjll, and the logic control circuit 15
When it is counted that the subsequent travel distance of the paper container is equal to the distance d from the paper travel reference position to the cutting position bottle, the 7-lip flop 16 is driven by the output signal. This flip-flop 16 drives the driver 17 and turns the clutch of the clutch/brake 10 to 0F.
FKL and the brake are turned on to temporarily stop the surrounding plate of the feed roller 8, and at the same time, the driver Is is driven to operate the cutter 7. Reference numeral 19 denotes a photosensor for detecting paper cutting, which resets the flip-flop 16 when paper cutting is confirmed.

When the printing of one job is completed and the boundary between the pages to be cut reaches the transfer charger 4, which is the reference position for paper travel, the counter 14 starts counting the amount of paper travel, and the amount of paper travel is calculated between the transfer charger 4 and the cut. -7, the feed roller 8 is stopped via the force shifter 14Fi flip-flop 16, driver 17 and clutch Q-brake 101, and the cutter is operated via the flip-flop 16 and driver 18. In this way, when the feed roller 8 stops, the page border li of the cutting special paper 5 is at the position of the cutter 7. will be cut off. On the other hand, in front of the tweed roller 8, the paper feed tractor 2 is stopped by the logic control circuit ISK, and the roller II & 5 continues to run until it is stopped, so it is placed between the feed row 98 and the fixing roller 3 to prevent the paper slack 5a. arise. However, this paper slack of 5 m is guided in a stable state by the guide brake (6) and 1 photo sensor (19).
When it detects that the paper 5 has been cut, it resets the flip-flop 16 and rotates the feed roller 8 faster than the paper transporter 8, so that it will not be absorbed by the instability of the paper 11 and cause a jam. do not have.

In this way, the counter 14 is used to count the amount of paper travel from the reference position (transfer charger 4), and the paper is cut based on this signal. It becomes possible to cut the paper 5 at the required page border I even if the paper length is twice as long as it is evenly spaced.

In the above embodiment, a case has been described in which a pair of rollers are disposed in front of the cutter as a means for stopping the paper traveling, but it is also possible to use a means that simply presses the paper. Also, if the stopping means is placed 11 in front of the engine,
As the cutting means, it is also possible to use a shearing type with a sharp blade wrapped around it, or a type that tears the paper by concentrating stress on the crevices.

As described above, according to the zero-start INK, when the page boundary of the paper to be cut is brought to the cutting position using the counter, the paper running stop means near the cutting position is operated, so that the page length of the paper can be adjusted. Paper can be cut at the required cutting position regardless of the cutting position. Furthermore, since there is no need to move the cutter according to the page length of the paper, the mechanism of the paper transport system does not become complicated, and there is no need to install four devices. play.
