Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device disposed between a copying machine and a sorter for conveying copy sheets from the copying machine to the sorter, and its purpose is to convey copy sheets to the sorter. allows the operator to visually check the status of the copy before it is copied;
It is also intended to make it possible to easily take out the jammed copy sheet when it is jammed.

By the way, if copy sheets ejected from a conventional copying machine are stored in the bin of a sorter, it is difficult to visually check the copy sheets because the sorter normally stores the sheets with the image side facing down to align the pages. Many positional defects and density adjustment defects occur. Particularly in high-speed copying machines, sorters are becoming indispensable, and the above-mentioned defective copy sheets are likely to occur. For this reason, when a sorter is selected, the first copy sheet is not transported to the sorter, but is ejected to a proof tray to check the finished state of the copy. A relay conveyor belt is installed between the copy sheet and the copy sheet with the image side facing up is pressed with a wire and conveyed by the relay conveyor belt, but since the copy sheet is exposed, it is exposed to This causes the edges of the copy sheet to lift up and cause jams.
The drawback was that it was difficult to remove the jam.

According to the present invention, a conveyance device consisting of upper and lower guide plates is provided between the copying machine and the sorter, and the upper guide plate is made transparent and can be opened and closed, thereby eliminating the drawbacks of the conventional apparatus.

Next, one embodiment of the present invention shown in the accompanying drawings will be described in detail. As shown in FIG. 1, a conveying device C of the present invention is disposed between a copying machine A and a sorter B.
The conveyance device C has a lower guide plate 2 on one side of which the upper part of the conveyor roller 1 is exposed on the surface, and an upper guide plate 4 made of a transparent material on which the lower half of the steel balls 3 are exposed on the lower surface.
The upper guide plate 4 is attached on one side with a hinge or the like so that it can be opened and closed freely, so that the steel balls 3 lightly touch the conveying rollers 1.
A grip portion 4a is formed on the other side, and a through hole 4b is formed on the upper surface. The rotating shaft 5 of each conveying roller 1 protrudes from one side of the lower guide plate 2, and a belt 7 is suspended from a pulley 6 fixed to the end thereof, and the belt 7 is driven by a sorter B. The lower guide plate 2
One end of the bar 9 is rotatably attached to the part of the sorter B facing the receiving roller 8, and the bar 9 of the other end is connected to the copying machine A.
It is adapted to be placed and engaged from above in an engagement recess 11a formed on the upper surface of the lower bracket 11 of the discharge roller 10. At this time, the entrance 13 of the conveying device C
is arranged to face the ejection roller 10 of the copying machine. 14 is the paper feed tray of copying machine A, 1
5 is a paper feed cassette, 16 is a transfer section, and 17 is a fixing roller. 18 is a switching plate of sorter B, 19 is a proof tray, 20 is a vertical conveyance section, 21 is a deflection unit, and 22 is a bin.

Next, the effect will be explained. The copy sheet discharged from the discharge roller 10 of the copying machine A is fed between the upper and lower guide plates 2 and 4 from the entrance 13 of the conveyance device C, and is held in front by the rotating conveyance rollers 1 and steel balls 3. is transported to sorter B's receiving roller 8.
After passing through the switching plate 18 which has been switched downward, the pages are stored in a predetermined bin 22 in page order with the image side facing down by the vertical conveying section 20 and the flattening unit 21. When the copy sheet passes through the conveyance device C, the image side is facing up, so the transparent upper guide plate 4
The copy status can be viewed directly through the . When a jam occurs, hold the grip portion 4a and rotate the upper guide plate 4 upward to open it and remove the jammed copy sheet.

According to the present invention, it is possible to directly check the image density and transfer position of the copy sheet facing upward through the transparent upper guide plate while the copy sheet discharged from the copying machine enters the sorter. Only the steel balls are placed on the upper guide plate and there are no other parts, so they are easy to see, and the conveyor rollers and steel balls are used to hold and convey them, so jams are unlikely to occur. However, in the event that a jam occurs, open the upper guide plate. Jammed copy sheets can be easily removed, and the upper guide plate has through holes that allow the heat and moisture from the copy sheets, which are heated during fusing and contain moisture, to be removed to the outside. In addition, the upper guide plate can be prevented from becoming foggy or deformed, resulting in poor contact between the steel balls and the conveying rollers, resulting in poor conveyance.Also, since a space is formed at the bottom of the conveying device, it is possible to prevent paper feed cassettes from forming. The sorter can be docked even if the type protrudes from the copier.
