Abstract

PURPOSE:To make a sheet loadable after the orderless sheet tilts a tray frontward, turning a recording surface upside while the paged sheet tilts the tray backward, turning the recording surface downside, by making a sheet discharge tray attachable to a sheet discharge tray device in a way of tilting it before and behind to the vertical direction. CONSTITUTION:In the case where copied sheets to be obtained out of individual originals are housed, if an on-claw 3b of a link 3 is engaged with an engaged hole 7 and a sheet discharge tray 1 is fixed to a tilting position at the front side, a sheet 10 to be discharged out of a pair of sheet discharge rollers 8 and 9 is guided by a guide 6 and the copying surface 10 is loaded on a front side mount surface 1a in the upside. Next, in case of being copied out of paginated originals, if an on-claw 3a is engaged with the engaged hole and the tray 1 is fixed to a tilting position at the rear side, the sheet 10 discharged out of these rollers 8 and 9 is turned over and fed to the tray 1, and it is loaded on a rear side mount surface 1b as turning the copying surface 1a downside. Therefore, the sheet copied from the first paper is set to the lowermost layer and the first page sheet turning the copying surface downside is situated in the lowermost layer whereby they are loaded in the page order as turning the copying surface downside, thus they are kept intact, dispensing with the page arrangement.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application Field The present invention is applicable to image forming apparatuses such as copying machines or image forming apparatuses, or recording apparatuses such as printing apparatuses such as printers or league printers. The present invention relates to a sheet ejection tray device (referred to as a subtraction sheet ejection device) that stores recorded sheets.

(B) Prior Art Generally, in this type of paper discharge tray device, the paper discharge tray is mounted on a recording device horizontally or slightly inclined, and its orientation is fixed.

On the other hand, a sheet discharged from a recording device such as the image forming device or printing device described above is discharged with the recording surface facing in a fixed direction, generally upward.

←→ Problem to be Solved by the Invention By the way, in the above-mentioned paper output tray device, when storing a plurality of recording sheets obtained from − sheets of original documents, they are sequentially placed on the paper output tray with the recording surface facing upward. There is no problem if you load it. However, files with a fixed page order,
If an attempt is made to copy from a document such as a document to the top of the page, the first page will be stacked on the paper ejection tray with the recording surface facing upward, and the subsequent pages will be stacked on top in order. Therefore, in order to organize the recorded sheets after the recording is finished, it is necessary to turn over all the sheets, which is a disadvantage that it takes a lot of effort.

(5) Means for solving the problem The present invention aims to solve the above-mentioned problems,
The present invention is characterized in that the paper discharge tray device is provided with a mounting means that allows the paper discharge tray to be mounted on the recording device by tilting the paper discharge tray to the front and rear sides with respect to the vertical direction.

g) Effect By employing the above means, when storing a plurality of recording sheets produced based on -sheets of originals, the paper output tray is mounted on the recording device with the paper output tray tilted forward, and the recording surface is facing upward. Load the paper onto the output tray with the

When storing recording sheets that are created in page order, the paper output tray is tilted to the rear and installed in the recording device, and the output tray is inverted and placed in the first tray with the recording surface facing downward. Load in order from page to page.

(F) Embodiments Hereinafter, embodiments embodying the present invention will be described with reference to the drawings.

A paper ejection tray 1 having a heptagonal cross-sectional shape is rotatably mounted on a shaft 2 provided in the main body of the copying machine located on the right side of the figure. The paper ejection tray 1 has a front loading surface 1a on which a sheet is placed when the tray is tilted to the front side (in a direction approaching paper ejection rollers 8 and 9 described later) with respect to the vertical direction, and a rear side (a sheet ejection surface described later). It consists of a rear loading surface 1b on which a sheet is placed when tilted in the direction away from the rollers 8, 9), and a link 3 that constitutes a mounting means together with the shaft 2 is attached to a joint portion at the upper part of the rear loading surface rb. 4 and is rotatably connected. The link 3 is provided with hooks 3a and 3b for fixing the mounting position of the paper output tray, and the inner hook 3b is inserted into a locking hole 7 made in the paper output guide 6 of the copying machine main body.
By re-engaging, the paper discharge tray is tilted forward as shown in FIG. 1, and by engaging the outer latch 3a, it is fixed in a tilted rearward direction as shown in FIG. 1
0 is a sheet that has been copied, and the copy surface is 1 oa*6 Tl above.
Then, the paper is discharged into a paper discharge tray by a pair of paper discharge rollers 8 and 9 of the main body of the copying machine.

Since this embodiment has the above-described configuration, when storing one or more copies of sheets 1- obtained from individual originals, the hook 3b of the link 3 is engaged with the locking hole 7. At this time, the paper ejection tray 1 is fixed in the forwardly inclined position shown in FIG. 1. In this state, the paper ejection roller pair 8,
The sheets 10 discharged from the sheet discharge tray 1 are guided by the guide 6 and stacked on the front loading surface 1a of the paper discharge tray 1 with the copying surface 10a facing upward.

On the other hand, when copying one page at a time from an original with all pages aligned,
Engage the hook 3a of the link 3 with the locking hole to close the paper output tray 1.
is fixed in the rearwardly inclined position shown in FIG. In this position, the sheet 10 discharged from the pair of paper discharge rollers 8 and 9 is fed into the paper discharge tray 1 in an inverted state, and is stacked on the rear loading surface 1b with the copy surface 10a facing downward. Therefore, the copy sheets that are copied in order from the first page are stacked with the first page sheet with the copy side facing down in the bottom layer, and the sheets with the copy side facing down in the order of the pages, If you just take out the page after copying is complete, there is no need to organize the pages.

In the above embodiment, the paper output tray is rotated and fixed, but it can be attached to and detached from the recording device at two different positions, and the attachment can be done by changing the position. The direction of inclination may be changed.

In addition, although an example has been shown in which the paper is applied to a recording device in which the recording surface is ejected upward, it is of course applicable to a recording device in which the recording surface is ejected downward. The functions performed by the front and rear sides are reversed.

(g) As described in detail, according to the present invention, the paper ejection tray is provided with a mounting means that allows the paper ejection tray to be mounted on the recording device by tilting the paper ejection tray to the front and rear sides with respect to the vertical direction. Therefore, when copying a document in any order, the document can be stacked on the paper ejection tray with the recording surface facing upward, and the recording state can be checked as necessary. On the other hand, when copying originals with aligned pages in order, change the position of the paper output tray, stack the paper on the paper output tray with the recording side facing down, and then take out the documents all at once. It is possible to save the effort of arranging the pages in order.
