Abstract

PURPOSE:To improve the accuracy of paper catching, by making up a catch tray with a bristle-planted pat whose bristles are designed to tilt downward stuck to the inner wall of a stopper of the catch tray. CONSTITUTION:A bristle-planted pat 8 made up in brushlike form, of which bristle tips are tilted downward, is attached to the inner wall of a stopper 6 of a catch tray 4. With this constitution, a sheet of copying paper sliding down on the catch tray is caught by downturn-bristle tips of the pat 8. Therefore, a fear of paper's overrunning the stopper and/or dropping is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION Kiza e1 Akira relates to the box, the catch tray of the child-shaking camera, and the quality of the catch tray.

In Tit copy copying machines, depending on environmental conditions such as the degree of moisture absorption of the copy paper, the paper that is ejected from the machine after the prescribed copying process may curl. It is known that this phenomenon frequently appears in machines that use a fuser.

When such curling of the copy paper occurs, the leading edge of the copy paper often climbs over the stopper of the catch tray and falls, causing a paper jam. Particularly in large copying machines for copying drawings, the degree of curling is large and the above-mentioned problems frequently occur.

-! ! In addition, some of the conventional paper sheets have a paper guide provided in the catch tray, and in this case, the paper is often misaligned.

Even if a tJ vapor guide is provided, if the paper is curled as described above, there is a drawback that the paper may run over the stopper of the catch tray or fall from the cap tray.

The present invention has been made in order to improve the defects of the conventional catch tray as follows.
The purpose is to present a catch tray where you can pick up the pads.

Hereinafter, the present invention will be explained in detail based on embodiments shown in the drawings.

FIG. 1 is a partially cut-away top view of a catch tray for removing a stopper that is installed in the most common conventional copying machine.

Copy paper that has undergone printing, transfer, and fixing is transported by a paper transport 1, and guided by a guide baffle 2 provided near the end of the copy paper, the leading edge of the paper is transferred to a pair of ejection rolls 3.
．． A downwardly inclined catch tray 4 is disposed in front of the pair of discharge rolls 3.3 in the paper discharge direction, and the paper is deposited therein. A paper presser 5 such as a Mylar (trade name) strip is lowered from above the catch tray 4.

The catch tray 4 also has a stopper 6 for blocking the leading edge of the paper to prevent the accumulated paper from falling from the tray. erected.

In the conventional catch tray configured as described above, when the ejected copy paper is curled to a large degree, the leading edge of the copy paper advances beyond the stopper 6.6 and is pushed away from the gap tray. As mentioned above, falling paper may disturb the alignment of the stacked paper.

Therefore, the present invention provides i? As shown in Figure Is2, the inner wall of the stopper 6 of the catch tray 4 is planted with plush hair,
In addition, by increasing the number of flocked pads 8 whose tips are inclined downward, the tip of the paper is completely blocked by the inner wall of the stopper.

As shown in FIG. 3, the flocked pad 8 is made of, for example, animal hair, synthetic hair, thread, or the like having a length of about 3II++1, which is implanted with the tips slanted downward, on the inner wall of the stopper 6, as shown in FIG. It is attached using double-sided adhesive tape. Note that the notch 9 provided in the middle of the stopper 6.6 at the front end of the catch tray is provided for taking out several sheets of paper.

The catch tray 4 configured as described above stores the copy paper ejected from the ejection roll pair 3.3 after copying is completed. It slides on the tray 4 and touches the stopper 6.6.

At this time, since the inner wall of the stopper 6.6 is provided with a brush-like flocked pad 8.8 whose bristles are inclined downward, the tip of the paper paper enters the brush-like flocked part. There is no IRi''L that escapes from the flocking section again and further crosses the stopper, and all the sheets stored in the catch tray are piled up in an orderly manner.

7i: Oh, the present invention is not a general large-scale machine that is configured so that the tip of the catch tray is tilted downward as in the embodiment described above, but is configured so that the tip of the catch tray is tilted upward. Although this is often the case, it can also be applied to a stopper installed at the rear end of the catch tray of a small machine.In this way, the trailing edge of the paper ejected first and the leading edge of the paper ejected next can be separated. This has the effect of preventing paper interference and preventing disturbance of the alignment of sheets on the catch tray.
