Abstract

PURPOSE:To use a double face copy tray for multiple purposes by switching the exit side of the tray for double face copy provided in a copying machine body to two carrying paths by a gate and connecting one carrying path to an ejection exit and connecting the other to a normal form carrying path. CONSTITUTION:The exit side of a fixing device 10 is switched and connected to a form inverting mechanism 5, a tray 12, and an ejection path 13, and the ejection path 13 is connected to an ejection exit 14, and the exit side of the form inverting mechanism 5 is connected to a tray 3 for double face copy. Forms in this tray 3 are sent to the first and the second carrying paths 17 and 18 by a feeding roll 16, and the first carrying path 17 and the second carrying path 18 are connected to the ejection exit 14 and a normal form carrying path 11 respectively and are switched and operated by a gate 19. Forms sent to an entrance 21 of a paper collator 20 are sorted and stored in bins 22. When the gate 19 is switched to connect the exit side of the tray 3 to the second carrying path 18, stored forms are sent to the normal form carrying path 11 to copy pictures on both faces similarly to a conventional device.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a copying machine equipped with a tray for double-sided copying and capable of automatically performing double-sided copying.

Conventional technology Equipped with a double-sided copying tray and a paper reversing mechanism (inverter), the single-sided copy paper that has been copied on one side is flipped upside down by the paper reversing mechanism, and outputted to the double-sided copying tray, and then the single-sided copying is performed again on the double-sided copying tray. A copying machine that feeds paper into a normal paper conveyance path, copies on one side of the remaining sheet to make double-sided copy paper, and then discharges the double-sided copy paper from an output port to a tray or a collating machine.

Problems to be Solved by the Invention The duplex copying tray only sends paper to a normal paper transport path, and can only be used for duplex copying operations.
This is wasteful both in terms of space and cost.

Means and Effects for Solving the Problem: The duplex copying tray is set in such a way that the paper can be fed to the ejection port, and the uncollated copy paper set in the duplex copying tray is sent to the collating machine for collation. [Combined paper, partition] Paper is sent to the collating machine and partition paper can be automatically inserted into the collated copy paper, making the tray for double-sided copying more versatile.

Embodiment FIG. 1 is a front view of a copying machine. The copying machine body 1 includes a belt-shaped photoreceptor 2, a double-sided copying tray 3, and a normal tray 4.
, a paper reversing mechanism 5, etc. are provided, and a transfer device 6, a developing device 7, etc. are provided around the photoreceptor 2, and the original image on the platen S is illuminated onto the photoreceptor 2 by an optical system 9, and is developed. After being developed into a toner image by the machine 7, the toner image is transferred to paper by the transfer device 6, and fixed by the fixing device IO.

The paper feed sides of the double-sided copy tray 3 and the normal tray 4 are connected to each other by the transfer device 6i in the normal paper conveyance path 11.

The exit side of the fixing device 1o is connected to the paper reversing mechanism 5, the tray 12, and the ejection path 13, and the ejection path 13 is connected to the ejection port 14.The exit side of the paper reversing mechanism 5 is connected to the tray 3 for double-sided copying. be.

The paper in the double-sided copying tray 5 is moved by the feed roller 16 to the first. 2nd conveyance path +7. I8, the first
The conveyance path 17 is connected to the discharge port 14, and the second conveyance path 18 is connected to the normal paper conveyance path 11, respectively, and are switched by a gate 19 as shown in FIG.

A collating machine 20 sorts and stores sheets fed into an entrance 21 into bins 22.

Then, the gate 19 is switched and the double-sided copy tray 3 is opened.
By connecting the exit side of the paper to the second cliff feed path 1gK, it is possible to feed the stored paper and the normal A conveyance path 11, so that double-sided copying can be performed in the same manner as in the conventional method.

By switching the gate 19 and connecting the exit side of the double-sided copy tray 3 to the first transport path 17, the stored paper can be transferred to the output port 1.
4, uncollated copy sheets can be stored in the double-sided copy tray 3 and collated by the collating machine 20 by driving only the feed roller I6. The partition paper is stored in the bin 22 of the collating machine 20 by driving the feed roller 16 in synchronization with the normal copying operation, and the partition paper is placed between the collated copy sheets. can be inserted.

Effects of the Invention Uncollated copy sheets can be fed to the ejection port 14 using the double-sided copying tray 3 and collated using the collating machine 2o.

Claims (1)

[Claims] The exit side of the double-sided copying tray 3 provided in the copying machine main body 1 can be connected to the first or second conveyance path 17, 18 by a gate 19, and the first conveyance path 17 is connected to the discharge port 14. A copying machine characterized in that a second conveyance path 18 is connected to a normal paper conveyance path 11.
