Abstract

PURPOSE:To fold a copied paper efficiently with less labor by supporting vertically movably an ascending and descending body which holds many folding line forming needles projected down toward a virtual folding line. CONSTITUTION:The copied paper to which an image is transferred and fixed in a copying machine 1 is ejected to a copy tray 5; and when the virtual folding line of the copied paper P reaches a through groove 16 which pierces the copy tray 5 vertically, power is supplied to electromagnetic cylinders 8 and 8'. Then, plungers 12 and 12' inserted to electromagnetic cylinders 8 and 8' are pulled downward, and an ascending and descending body 10 is moved downward along guides 9 and 9'. Many folding line forming needles 15 planted in the lower end of the ascending and descending body 10 press the virtual folding line part of the copied paper P, and the copied paper P is received on a tray 18 for folding. Thus, the copied paper is folded automatically and mechanically.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention automatically transfers tN photos or objects from one to one.
Scraps 3) Rukokichi's cheap copying machine paper folding ↑ 15.
1.

Conventionally, in the case of 11 photocopies, the original is placed on the transparent plate for placing the original, which is aligned with the focus of the optical system. 0) To save paper, there are cases where a book is opened, the entire page is copied, and the first copy is folded in half.

In addition, for users who use photocopies, the maintenance and management costs for a single photocopy are calculated in proportion to the number of times the photocopy is used, so it is more economical to use it less frequently. Copy size (for first-time listeners) of paper twice the size of the monthly paper) Copy a small amount of paper, and divide the 21-piece material into 2 pieces into 4 pieces.
It was often necessary to cut it and use it.

This first-heard work 2, which consists of 4 copies of copy 1, is relatively common, or when the copy was folded, V) was accompanied by a picture of a bale of -m''. The process of taking paper out of paper and folding it by operating a paper knife is tedious and time-consuming, and the work efficiency is extremely poor.Therefore, there was a demand for the development of a more convenient paper folding device a. .

Therefore, this invention has been developed to provide original photo paper P discharged to the copy receiver 5.
Directly below the imaginary fold line of the copy paper 1゛θ), a through groove 16 is formed which passes through the Co 1-receiver 11+15 in the 20 direction. ■Memorial photo paper P
Immediately above the imaginary fold line, a large number of 47r, which are clear to the imaginary fold line, all protrude downward toward the imaginary fold line.

The main object of the present invention is to provide a copying machine paper folding device that can efficiently fold copy paper with little effort.

An embodiment of the present invention will be described above with reference to the drawings.

It is discharged into the pipe receiver 5. What about this copy reception 11115? (fd for intermediary copying machine to fold copied copies)
A ripping device 6 is also provided.

Further, on the bottom wall of the copy tray 5, a folding tray 1+1118 is provided for receiving the folded copy paper.

To explain the structure of this copying machine paper folding device 6, as shown in FIGS. A pair of electromagnetic cylinders 8, 8' are provided inside the electromagnetic cylinders 8, 8' facing each other with an interval between them. A vertically moving body 10 is arranged as shown in FIGS. 2 and 4. At both ends of this vertically moving body 10 are

, 11' is a plunger 1112 whose base 'Ahi part is inserted into the electromagnetic cylinder 8, 8', and whose tip Mj: a part protrudes from the electromagnetic cylinder 8, 8'.
l2' is fitted.

At the lower end of the elevating body 10, there are a number of folds protruding downward toward the imaginary fold line of the copy sheet discharged onto the copy tray 5. - The forming needle 15 is implanted.

The plunger 12, 12' has a flange 1.

When released, the plan and gloss 12, 12' return to their return positions due to the action of the return spring 14, and the plan and gloss 12 return to their original positions.

In this embodiment, the vertical movement of the elevating body 10! 1i

is formed on the copy tray 5. 17.17 is the step-breaking body 17. ．． ! The slit formed between the copy tray 5 and the copy tray 5 is also formed so that the photo paper P passes through the copy tray 5.

Next, to explain the operation of the above-mentioned 41'q copy machine paper folding tray 6, as shown in FIG. The copy paper is fed, the image is transferred in the copying machine 1, and the copy paper is ejected to the copy tray 5, and the copy paper P or its imaginary folding line is Kaichi 11' ”n 1ll

2, 12' is pulled downward, as shown in FIG.
The elevating body 10 connected to the guides 9, 9' moves downward, and the downward movement of the elevating body 10 causes a large number of 41/1 installed at the lower end of this elevating body 10 to move downward. The fold line forming needle 15 presses a portion of the virtual fold f1.1 of the copy paper P, and as a result, the copy paper IJ is folded around this virtual fold portion and received in the folding tray 18. When the copy paper 1) has been folded, when the electromagnetic cylinders 12 and 12' are de-energized, the electromagnetic flips 8 and
The proximal end is dwarfed by 8'.
2 and 12' are returned to the JI position by the action of the return spring 14, and at the same time, the silanger 12,
The elevating body 10 connected to the sheet 12' also rises to the side, and the folding line forming needle 15 also comes into contact with the copy paper P by 1ζ[1.

As explained above, since the present invention has the above structure, it is now possible to automatically fold the copy paper by a machine instead of the conventional method of folding the copy paper by 17i. 3. The copying machine is equipped with an elevating body that holds a large number of fold line forming needles, making it possible to continuously fold the copy paper at the same time as it is being copied, making the copying process easier. There are advantages such as streamlining.
