という欠点があつた。 In a conventional copying machine, as shown in Figs. 1 to 4, the loading length l of paper feed cassettes a and b of different sizes into the main body c of the copying machine is the same for the upper and lower paper feed cassettes, and If the paper feed cassette b for A-4 paper is installed in the upper shelf as shown in Figure 1, and the paper feed cassette a for B-4 paper is installed in the lower shelf, or the upper and lower B・4 paper or A・
When paper feed cassettes of the same size are installed, such as four paper feed cassettes, the rear edges of the upper and lower paper feed cassettes are on the same surface, so the size display provided on the rear edge side This is not only easy to see, but also has a good appearance.As shown in Fig.
When paper feed cassette b for A/4 paper is installed in the lower shelf, the upper paper feed cassette a protrudes beyond the lower paper feed cassette b, so it must be installed at the rear end of the lower paper feed cassette b. This not only makes it impossible to see the displayed size, but also makes it unsightly.
この発明は上記の事情を考慮してなされたもの
で、その目的とするところは、上下の給紙カセツ

ける給紙装置を提供しようとするものである。 This invention was made in consideration of the above circumstances, and its purpose is to make the length of loading the upper and lower paper cassettes into the copying machine body longer than the lower cassette, and to By making the difference in the length of the paper feed cassettes equal to or greater than the difference in length between the upper and lower paper feed cassettes themselves, the lower paper feed cassette always protrudes more than the upper paper feed cassette, making it easier to install and remove the paper. An object of the present invention is to provide a paper feeding device for a copying machine that can improve performance.

れ、トレイ２０に排出されるようになつている。 An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIG. 5, 1 is a main body, and inside this main body 1, an image carrier 2 made of a photosensitive drum is rotatably provided as shown by an arrow. and,
A charger 3, a developing device 4, a transfer device 5, a peeling device 6, a static eliminator 7, and a cleaning device 8 are provided on the outer periphery of the image carrier 2 in this order in the rotational direction. On the other hand, a document table 9 is provided at the upper part of the main body 1 so as to be movable back and forth as shown by arrow A. A light source 11 having a reflection plate 10 is provided below the document table 9, and is adapted to illuminate the document 12 placed on the document table 9. The reflected light from the original 12 is transmitted to the image carrier 2 which is rotated by a convergent light transmitter 13 provided below the original table 9.
The image of the document 12 is transmitted. Further, an upper cassette mounting part 14 with a charging length L 1 and a lower cassette mounting part 15 with a charging length L 2 are provided below the main body 1 . It is longer than the charging length L2 of the cassette mounting section 15. A paper feed cassette of any length, for example, an A.4 or B.5 paper feed cassette, can be mounted to these mounting portions 14 and 15. In addition, these upper and lower cassette mounting parts 14
and 15 have paper feed rollers 16 and 1, respectively.
7 is provided and constitutes a paper feed section 21. The transfer paper P 1 or P 2 selectively fed from the paper feed section 21 is supplied to the image carrier 2 from before the transfer device 5 via the paper feed device 18 . The transfer paper P 1 or P 2 transferred by the transfer device 5 is peeled off from the image carrier 2 by a peeling device 6, fixed by a fixing device 19, and discharged onto a tray 20.

給紙カセツトＡはL1〜L2だけ突出する。 Next, the operation of this invention configured as described above will be explained. As shown in FIG. 5, paper feed cassette A containing A.4 transfer paper P 1 is mounted on the upper cassette mounting portion 14, and paper feed cassette B containing B.4 transfer paper P 2 is mounted on the lower cassette mounting portion 15. When the lower paper feed cassette B is installed, the lower paper feed cassette B and paper feed cassette A are located L 1 - L 2 more than the upper paper feed cassette A.
It protrudes by the length of the difference α. Also, the 6th
As shown in the figure, when the same B/4 paper feed cassette B is installed, the lower paper feed cassette B protrudes by L1 - L2 . Similarly, as shown in FIG. 7, even if A and 4 paper feed cassettes A are installed above and below, the lower paper feed cassette A protrudes by L1 to L2 .

写紙の補給も容易になり、使い勝手が向上する。 As explained above, the loading length of the upper paper feed cassette is longer than the loading length of the lower paper feed cassette.
Moreover, the difference in loading length between the upper and lower paper feed cassettes can be
Since the length is longer than the difference in length between the upper and lower paper feed cassettes, the lower paper feed cassette always protrudes more than the upper paper feed cassette, which not only improves the appearance but also helps when the installation space is small. If the upper paper feed cassette protrudes more than the bottom, it eliminates the trouble of having to remove the upper paper feed cassette first before attaching or removing the lower paper feed cassette, making it easier to attach and detach. Furthermore, the size display provided at the rear end of the lower paper feed cassette can be easily checked, and the replenishment of transfer paper to the lower paper feed cassette is also facilitated, improving usability.
