Abstract

PURPOSE:To eliminate the need for the space in a copying machine body for inverting a form and reduce the copying machine and a sorter in size by projecting the form into air so that it crosses the discharge path of an original, and turning over the form. CONSTITUTION:The gathering of a form 6 is selected and an original 2 is supplied from the 1st page onto a platen 3 by a manual insertion or automatic original feeder 4 to start taking a copy. Part of the form 6 conveyed on a form ejection path 7 is projected into air from a form ejecting port 1b by path changeover guides 10 and 15. The ejection path 18 of the original 2 crosses the form 6. The tip of the path changeover guide 15 of a form inverting mechanism is projected onto the form ejection path 7, and an inverting roll 16 is reversed to send the form 6 from a ejecting port 1a into the sorter 13, gathering the form in respective bins 17 of the sorter 13 successively. Then, the original 2 on the platen 2 is ejected into a paper ejecting tray 19.

Description

DETAILED DESCRIPTION OF THE INVENTION This field of industrial application relates to a copying machine provided with a sheet reversing mechanism so as to intersect with the discharge path of the original sheet 11.

Prior Art Conventionally, as shown in Fig. 1, there is an automatic document feeder that automatically feeds the original to be copied onto the platen on the upper part of the copying machine main body σ, and an automatic document feeder S is installed on the top of the copying machine main body σ, and on the processing paper discharge side of the copying machine main body α. Sorter c that collates the 11L scoops that are continuously discharged from the main body of the copying machine.
In the fz-equipped copying system, since it is necessary to make copies sequentially from the last page of the original, operational errors are likely to occur, and space is required in the copying machine main body α and sorter C to reverse the paper. For.

There was a problem in that the copying machine body a and the sorter C were large.

OBJECT OF THE INVENTION The present invention has been made for the purpose of improving such problems, and provides a copying machine that is capable of reversing paper without requiring a full space within the main body of the copying machine.
This is an attempt to downsize copying machines and sorters.

1. Structure of the Invention The first feature is to provide a paper reversing mechanism near the paper ejection port of the main body of the copying machine, which protrudes the paper to be inverted into the air, intersecting with the document ejection path, and completely inverts the paper from front to back. A copying machine that does not require space inside the copying machine to turn over paper.

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to the drawings shown in FIG. are doing.

Reference numeral 4 denotes an automatic document feeding device provided on the platen 3, and is configured to feed the documents 2 placed on the document tray 5 onto the platen 3 one by one from the first page. The copying machine body 1 also includes an optical system that exposes the original 2 placed on the platen 3 and guides reflected light from the original 2 to the photoreceptor, and an electrostatic latent image formed on the surface of the photoreceptor. a developing device for developing the toner image, a transfer device for transferring the toner image developed by the developing device onto the paper 6, and a fixing device for fixing the toner image transferred to the paper 6 (all not shown). etc. are arranged in layers with a constant θf, and the paper 6 on which fixing has been completed passes through the paper ejection path 7 to the copying machine main body 1.
Paper outlet 1αL provided on the side of the paper outlet 1αL! 2 Copy machine body 1
It is sent into a sorter 13 installed on the side of the sorter 13, and stored and deposited in, for example, a bin 17 at the top of the sorter 13.

On the other hand, a route switching guide 1 is provided in the middle of the paper discharge path 7.
0 is provided, and when collation of the sheets 6 is selected during copying, the conveyance direction of the sheets 6 conveyed through the sheet conveyance path 7 is switched to the opposite side of the sheet transfer path 11. The paper reverse transfer path 111 communicates with a paper discharge port 1b opened at a corner of the main body I of the copying machine.

Further, a paper reversing mechanism 14 is provided between the route switching guide 10 and the paper discharge port 1b.

The tip of the paper reversing mechanism 14 is the paper discharge port 1b111.
Route switching kite 15 facing toward 11 and paper outlet 1b
A reversing roll 16 located near the reversing roller 16 is arranged to reverse the front and back sides of the paper 6 in the next process.

When copying is started by selecting collation of the paper 6 and feeding the original 2 from the first page onto the platen 3 by manual feeding or by the automatic JM document feeder 4, the paper 411 provided at the output path 7 Route switching [do (o e r 5
is in the state shown in Figure 4 (Aj), and the paper 1
A part of the paper 6 that has been conveyed above is projected into the air through the paper discharge port 1bL.

At this time, the υ1 output path 18 of the original offloader 42 and the paper 6 intersect.

Next, at the same time as the tip of the path switching guide 15 of the paper reversing mechanism 14 projects to the paper tJl output path 7.

The reversing roll 16 reverses, and the paper 6 projected into the air from the discharge port 1α is sent into the paper discharge port 1bL resorter t3 through the path shown in FIG. collated. Thereafter, the original 2 on the platen 3 is ejected to the paper tray 19, so even if the paper 6 to be reversed intersects the ejection path of the original 2, no problem will occur, and the paper 6 will not be placed inside the copying machine main body 1. No space is required for inversion.

Thereafter, while repeating the above operation, the first number of originals 2 are copied one after another, and the copied sheets 6 are placed in each bin 17 in the sorter 13.
Collate inward.

In the above embodiment, the paper 6 to be reversed is placed in the paper outlet 1.
bLF) protruded into the air at an angle of approximately 45°, or the fifth (
2) As shown in FIG.
It is also possible to provide a paper discharge port IbJ and protrude directly from the document 2 discharge path. In this case, a cover 20 made of soft synthetic resin or the like and which can be opened and closed may be provided over the paper outlet 1b to completely prevent foreign objects from falling into the copying machine main body.

Effects of the Invention As described in detail above, this invention is capable of inverting a sheet of paper by protruding it into the air where it intersects with the original ejecting path. The paper reversing mechanism can be configured to be compact without requiring space for reversing the paper.This makes it possible to downsize the copying machine main body and sorter, and also reduces the possibility of operational errors since the first page of the original can be copied. You can also do less.
