Abstract

PURPOSE:To make it possible to sort and pile copying paper forms according to every different size by dividing the paper form piling surface of a catch tray in an electrophotographic copying machine, etc., such that the divided surfaces correspond to paper form size, and holding said divided surfaces at different angles along the paper form throwing direction. CONSTITUTION:A catch tray 3 for housing copying paper form is provided in front of a paper form discharging roll 2 of a copying machine 1, and a catch tray 7 for receiving the thrown copying paper forms different from the catch tray 3 in its size and separating the piling surfaces thereforis provided on the lower stage of said catch tray 3. A bending part 4 for preventing the catching collision of the tip of the paper form is provided on the large-sized paper form tray 3, and a stopper 5 for preventing paper form sliding-down is erected. Further, a notch 6 is provided in the central area of the catch tray 3, and a catch tray 7 is aranged within this notch 6. A bending part 8 and a tip stopper 9 are provided on the catch tray 7, and a notch part 10 is provided therebetween. Paper form with narrow width is housed into the catch tray 7 through the notch 6.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a multi-stage catch tray that can accommodate six different sizes of copy paper to be discharged into the catch tray of an electrophotographic copying machine or the like.

Generally, electrophotographic copying machines and the like can use paper of various sizes.

Therefore, the length of the catch tray that stores completed copies according to the above paper size in the paper input direction can be varied in two or three stages to prevent jams in the paper storage section. ing.

However, in actual copying work, it is often necessary to obtain copies of different sizes from originals of different sizes mixed in the lander 4, but as mentioned above, the length of the catch is variable only in the paper input direction. - Copying machines equipped with a tray are extremely inefficient because they have a mechanism that separates the KI height for each size and performs copying operations.

The present invention has been developed to solve the above-mentioned problems, and includes dividing the paper stacking surface of a plurality of catch trays that can accommodate different paper buoys so as to correspond to the widths of various paper sizes. It is an object of the present invention to provide a multistage catch tray that can hold these at different angles along the paper input direction.

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

FIG. 1 shows the structure of the multi-stage catch tray of the present invention. A catch tray 3 having a paper stacking surface of This is a multi-stage catch tray that holds the catch tray T and has catch trays T of different widths.

As is clear from the figure, the catch tray 3 is a large paper tray that accommodates, for example, A3 size paper, and the lower tray is a small paper tray that accommodates, for example, B4'F size paper.

The large size paper catch tray 3 has a discharge roll 2.
, 2 is provided with a bent portion 4 to prevent the leading edge of the paper from colliding, and a stopper 5 to prevent the paper from slipping off is provided at the leading edge of the bending part 4 to prevent the paper from falling.
5 will be erected. Furthermore, a deep notch 6 is provided in the center of the catch tray 3 beyond the bent portion 4, and a small-sized paper catch tray 7 on which small-sized papers are to be deposited is arranged within this notch 6. The operation is such that their hinges make it possible to provide the same plane as the surface of the large size paper catch tray 3 and the same level difference as the bending part 4.

FIG. 2 shows that when the small-size paper catch tray 7 is not used, the surface of the small-size paper catch tray 7 is moved to the same plane as the large-size paper catch tray 3 by hanging on the hinge mentioned above. FIG. 6 is a perspective view showing a state in which it is accommodated in the notch 6.

The small size paper catch tray 7 has a bent part 8 with a step in the same position and group as the bent part 4 provided in the large size paper catch tray 3, and a paper leading end stopper 9.
9 is set upright, and a notch @10 for taking out the number of sheets is provided between them.

As shown in the side view of FIG. 3, the above-mentioned small size paper catch tray 7 is rotated by a hinge 11 which is rotatably mounted on the back side of the penalty size paper catch tray 3 via a friction part. Do it like this.

Now, when sheets of different sizes are accommodated by the multi-stage catch tray of the present invention, paper with a small width is placed in the small size paper provided in one stage past the notch 6 of the large size catch tray 3. It is housed in a catch tray T. On the other hand, large-sized sheets are accommodated in the catch tray 3 because the side edges of the sheets are supported by the large-sized sheet catch tray 3.

In this way, the copy sheets of each size are separately fed into separate catch trays, making it easy to organize the completed copies, which has the effect of significantly increasing the efficiency of copying operations.

Furthermore, the stepped bent portions 4 and 8 provided in the vicinity of the discharge rolls 2 and 2 prevent the leading edge of the copy paper that is subsequently thrown in from colliding with the trailing edge of the copy paper stacked on the catch tray. Therefore, there is no risk of paper jams due to interference with copy paper, which is even more effective.

Although a two-stage catch tray has been described above as an embodiment of the present invention, the present invention is not limited to only a two-stage catch tray, but can also be applied to a three-stage catch tray or more as shown in FIG. The embodiment described above is a catch tray that can be applied to an order n-th center registration machine in which the document is positioned in the center of the document table and the paper also passes over the center line of the machine. The invention is not limited to paper, but can be applied to a machine for registration of roasted paper.

FIGS. 5 and 61 are a perspective view and a-side v1, respectively, showing an embodiment in which the multi-stage catch tray of the present invention is applied to a paper back registration machine. Paper rear side As is well known in the J registration machine, all copy paper 755 is conveyed along the rear side of the machine as seen from the operator's side, so the paper stacking surface on the rear side of the large size paper stacking tray is As shown in FIG. It is necessary to devise a method such as providing a bent portion 14 that hangs slightly in one direction on the free edge of the paper supporting portion 12 so as to catch the leading edge of the large-sized paper.

In addition, in machines where operator side registration is possible for both original documents and copy paper by using a collective optical system such as a SELFOC lens, the front side and back side of the tray shown in Fig. 5 above should be reversed. It should be obvious what you should do.

Since the present invention is configured as described above, even when originals of different sizes are mixed, there is no need to classify the originals by size before copying, and the copy paper is separated and stacked for each different chair. This has a significant effect on improving the efficiency of copying work.
