Abstract

PURPOSE:To facilitate the confirmation of the job name of paper, by folidng back the latter half part of a final page to a surface side when the final page of paper comes to back side. CONSTITUTION:A paper processing device 2 allows printed paper to pass through a paper folding-back means 6 to store the same in a paper stacker 7. The paper 3 is sent on a table 17 toward a direction shown by the arrow by a feed roller 13 and a cutter 5 cuts the paper 3 when a cutting order is imparted. When the printed surface of a final page is folded to back side, a folding-back indicating signal is imparted and a stopper 12 is operated, when the cutting order is received, to press the paper 3 but the paper 3 of a left part form the stopper 12 is succeedingly sent. Therefore, the paper 3 is sent while folded in a loop form along a paper guide 15 and, when the final end of the paper 3 is detected by a paper detector 8, a press plate 10 is fallen to press the paper 3 onto tht table 17. By this mechanism, the paper is folded in such a state that the latter half part of the final page of the paper is folded back to a surface side.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a paper processing device for a printing device that sorts printed continuous folded 4° toned paper sheets printed out from the printing device for each job.

Conventional technology A printing device that prints the output of an electric calculator prints out characters, etc. on paper while feeding continuous folded paper according to instructions from a central processing unit, and the printed paper is sent to paper processing for the printing device. The paper is folded and folded at each fold 11 by the device, and cut at each fold 11 by a cutting command sent from the central processing unit for each 11th job.

On the last page of the cut sheets, floral letters indicating the job name are printed to make it easier to sort the printed sheets. However, when the last page is folded with the front side facing up, the last page has to be opened each time to see the yellow color in order to determine the job name, which is inconvenient for sorting.

OBJECTS OF THE INVENTION The first object of the present invention is to solve the above-mentioned conventional drawbacks, and to sort the paper by displaying flower characters indicating the name of one job regardless of the number of pages of printed paper or even numbers. An object of the present invention is to provide a paper processing device for a printing device that is easy to use.

Composition of the Invention The paper processing device of the present invention is capable of handling continuous folds printed out from a printing device [1. Used paper is folded at the crease, and a cutting command is given at the end of the job r41J to cut the paper at the crease. In the paper processing device, the data blue L is transferred between the first feed roller for feeding the paper and the first feed roller.
A stopper which is arranged on the output side and holds the paper when the tJJ command is received when the last page of the paper is the number of pages or an even number and releases the paper when the switch described later is turned on; a first paper detector arranged at the tfSl to detect the end of the paper; a presser plate that descends to the table and presses the paper onto the table according to the output of the paper detector of the tfSl; and a lowering of the presser plate. and a second feed roller that feeds the paper held between the table and the presser plate when the switch is turned on, and when the last page of the paper becomes large, the second feed roller It is characterized by folding the back half to the front.

Embodiments of the invention Next, the invention will be described in detail with reference to the drawings.

FIG. 1 is a schematic diagram showing an embodiment of the invention. That is, the printing unit 4 of the printing device 1 prints on paper 3 in response to a command from a central processing unit (not shown), and the printed paper 3 is sent in the direction of the arrow from the printing device 1 to the paper processing device 2. Sent. Paper processing equipment W! , 2 simply pass the printed paper through the paper folding means 6 (until the last page is reached) and eject it, and the ejected paper is stored in the paper stacker 7. At this time, the paper is folded back at each fold [], and the paper is stored in the paper stacker 7 in a folded state iL. When one job is completed, when the fold 11 after the last page on which the final flower characters of the job are printed is sent to the position of the cutter 5 by the feed command from the central processing unit, the central processing unit sends the fold 11. The cutter 5 is driven by the command, and the paper is cut into zigs. If the last page of the paper is, for example, an even number, and the last page is the back side when the paper is folded and folded, the paper folding means 6 operates according to a folding instruction signal, which will be described later, sent from the printing device 1. , as shown in FIG. 2, the latter half of the final page is folded back in the direction of arrow a so that it is facing up, and then discharged to the paper stacker 7. 1' of the last page: Is it an f number or an even number in the printing device l? For example, in the case of an even number of pages, this information is sent to the sheet folding means 6 as a folding instruction 118.

FIG. 3 is a side view showing details of the sheet folding means 6. FIG. The paper 3 is transferred from the table 17'' to the first feed roller 13.
is sent in the direction of the arrow. The cutting machine 5 cuts the paper 3 when a cutting command is given from the central processing unit, and the cut paper is continuously fed and usually discharged from a paper guide 16 to a stacker. However, when the return finger 1\mail t) from the printing device is input,
When receiving the cutting command from the central processing unit, the stopper 12
presses the paper 3, and then when the switch 11 is turned on, the paper 3 is released.

Note that the stopper 12 is placed at approximately the center of the table 17, and when the cutting command is given, the stopper 12 is placed at the center of the table 17 to prevent the folded paper 3 from folding 11.

After the stopper 12 presses the fold position of the paper 3, when the paper 3 is continuously fed by the feed roller 13, the fourth
As shown in the figure, the final page of the paper 3 is bent at the crease position and fed along the paper kite 15 in a loop shape.

The 5S l feed roller 13 is placed on the left side of the collar 12 in the figure, and the second feed roller 14 is placed on the right side of the stopper 12. The second feeding port roller 14 is a roller that is driven only while the switch 11 is on to feed the river HE 3. The left side of the first feed roller 3 in the figure (
A first paper detector 8 is disposed on the feed side), and a first paper detector 8 is disposed on the table 1
A second paper detector 9 is disposed at the right end portion of 7 in the figure.

In addition, there is a u in the upper right corner of the table 17 in the lower right part of the figure.
A presser plate IO that can move f is arranged, and the presser plate IO
11 is a pinch roller that can be rotated. Reference numbers 15 and 16 are paper kites for guiding the paper 3.

Next, the operation of this embodiment will be explained. During normal printing, the paper 3 is sent by the first feed roller 13, guided by the paper kite 16, and placed in the paper stacker 7 by the V
[Served.] The cutting device 5 is connected to the central processing unit! ilJ
Cut command When all commands are issued, the paper is cut.

When the printed side of the final page is folded to the back, a folding instruction signal is given from the printing device 1, and upon receiving the cutting command, the stopper 12 operates to press down the paper 3, but the stopper The paper 3 on the left side of 12 continues to be fed by the first feed roller 13. Therefore, the paper 3 is bent into a loop shape and sent along the paper kite 15, as shown in FIG. When the end of the paper is detected by the first paper detector 8, the presser foot 10 is lowered to press the paper against the table 177. As a result, the latter half of the final page of the paper is folded back to the front side. - Due to the force and the lowering of the presser plate lO, the switch 11 is turned on and the stopper 12 is released, and the second feed roller 14 also starts operating and feeds the paper to the right in the figure, so the paper is guided to the paper guide. 16. Then, when the second paper detector 9 detects the discharge of the paper, the presser plate 10 is raised, the switch 11 is turned off, and the second feed roller 14 also stops feeding. That is, the process returns to the initial state yd; and prepares for the next process. It should be noted that if the last page is the front page in the normal state, the turn-back instruction signal from the printing device 1 is not input, so the stopper 12. Of course, the press plate lo5 does not operate, and the paper 3 is simply fed by the first feed roller 13 and is discharged from the paper kite 16 to the paper stacker 7.

As a result of the following operation, the paper stored in the paper stacker 7 in the folded state yl: will be folded half a page or to the front side if the last page is the back side, as shown in Figure Ei'S5. When the paper is returned, the flower characters indicating the job name printed on the final page can be confirmed by looking at the folded state of the paper.

Effects of the Invention As shown in I; in the present invention, when the last page of the paper is on the back side, the latter half of the last page is folded over to the front side, and the flower characters printed on the last page are placed on the front side. With this configuration, it is possible to easily confirm the job name of the paper.
