Abstract

PURPOSE:To efficiently use a copy discharge paper tray by using it as the upper cover when it is not used for copying, and setting it to a position where it does not obstruct to take out an original when it is used. CONSTITUTION:At the time of non-use, a copy discharge paper tray 12 and a copy discharge paper tray supporting leg 15 become a plane and cover an original discharge paper tray 7 and become a part of the facing. Also, at the time of using a copying machine, the tray 12 is raised by a handle 14. This tray 12 is attached pivotally so as to be rotatable to the body by a fulcrum 13, and the leg 15 is attached pivotally so as to be rotatable by a fulcrum 17 to the tray 12, slides in the direction for going to a copy discharge part 11 on a guide 18 of both side faces of the tip of the leg 15 by raising the tray 12, and is fixed to a depression of a lock part 19 provided on the guide 18 by a dead weight of the leg 15. Due to a fact that this leg 15 is fixed, the tray 12 maintains a slant face, and works as a copy discharge paper tray.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a copying machine having a mechanism for ejecting transferred paper from the upper part of the machine.

2. Description of the Related Art In most conventional copying machines, a paper feed cassette is provided on the side of the machine body, and copied paper is ejected from the opposite side. For this reason, an extra copy space equal to the size of the copy output tray provided on the side of the machine is required. In order to solve this problem, a copy paper ejecting mechanism was installed on the top of the copying machine.
This method has been proposed in Japanese Patent Application Laid-open No. 176759 and Japanese Patent Application Laid-open No. 60-6161.

Problems to be Solved by the Invention However, with the above-mentioned apparatus, when copying a large number of originals, the output tray is installed on the original cover, so when replacing originals and copying, the output tray cannot be used. Also, the problem arises that the ejected copy paper gets in the way.

Further, when a large amount of copy paper is ejected, if the load of the copy paper is supported only by the base of the paper ejection tray, problems such as insufficient strength of the paper ejection tray may occur.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a copying machine equipped with a document output tray on the upper part of the machine body. A copy output tray having a size that covers the paper tray is provided, and this copy output tray serves as a top cover that covers the top surface of the original output tray when the copying machine is not in use, and serves as a cover for covering the top surface of the original output tray when the copying machine is in use. It is located in a position that does not obstruct take-out.
The present invention also relates to a copying machine characterized in that it functions as a copy discharge tray for storing copy paper.

Example The present invention will be explained according to examples.

FIG. 1 shows an embodiment of the present invention when a copying machine is used. The original inserted from the original insertion section +11 is fed into the machine by the original transport roller (2), and then transferred to the reading section (20).
After passing through the document, it is reversed by the U-turn guide (3), sent by the document transport roller (4), and then returned to the U-turn guide (5).
The document is reversed and ejected from the document ejection section (6) onto the document ejection tray (forced).Furthermore, an electrostatic latent image corresponding to the image of the document obtained from the reading section (20) is transferred to the photoreceptor (21). ), and after being developed by a developing device (not shown), the fed transfer paper goes through the steps of transfer, separation, and fixing.
The conveyance rollers (9) discharge the two sheets from the discharge section (11) onto the copy paper discharge tray (12). In this embodiment, the document ejection section (6) is provided on the opposite side from the copy ejection section (11), but the configuration is not limited to this. Furthermore, although roll paper (8) is used in this embodiment, the structure is not limited to this, and a mechanism for feeding cut paper may be provided. Note that A indicates a document passing path, and B indicates a copy paper passing path.

When the copying machine shown in Figure 2 is not in use, the copy output tray (
12) The copy output tray support legs (15) (hereinafter referred to as support legs) are flat and cover the original output tray (covering the force and become part of the exterior. When using the copying machine (Fig. 1) To do this, lift up the copy output tray (12) using the handle (14).The copy output tray (12) is rotatably attached to the main body of the copying machine at a fulcrum (13).On the other hand, Support leg (1
5) is rotatably attached to the copy paper output tray (12) at a fulcrum (17X folded part), and the copy paper output tray (12)
By lifting the support leg (15), the pins (16) on both sides of the tip of the support leg (15) move the copy ejection section (11) over the guides (18) provided on both sides of the original ejection tray
) and is provided on the guide (18) by the weight of the support leg (15).
(θ≧900). Support legs (15)
is fixed, the copy output tray (12) maintains its slope and functions as a copy output tray. Further, since the support legs (15) that covered the document ejection tray (forced) are opened, the document can be taken out from the opening.

Note that when θ<90°, it is impossible for the support leg (15) to reach the lock position due to its own weight, so the handle (14) is provided on the support leg (15) side as shown in Figure 3 to lock it. It may also be pushed into the section (19).

Effects of the Invention In the copying machine of the present invention, the copy output tray does not interfere with taking out originals, and since the copy output tray covers the original output tray when the copying machine is not in use, there is no dust or dirt on the original output tray. etc. can be prevented from accumulating.

In the copying machine of the present invention, since the copy discharge tray is supported by the copy discharge tray supporting legs, the strength of the tray can be increased.

Further, in the copying machine of the present invention, since the copy output tray can be integrated with the copying machine main body, aesthetic harmony between the copying machine and the installation environment can be achieved, and the copying machine itself can be made compact.
