字形に折るようにした発明がある。The size of the paper feed cassette in conventional technical office machines is generally designed to accommodate sheets of size [35 to A3], which are frequently used. This is because the purpose is to make the length of the paper feed cassette protruding from the side of the office machine as short as possible. However, even though it is used infrequently, it is cumbersome to feed large sheets such as A2 size sheets while holding them with both hands. Various methods have been proposed for storing paper in this paper feed cassette. For example, JP-A-61-25
As described in Japanese Patent No. 4430, a support is provided at the rear end of the cassette case and faces the bottom surface of the cassette at a predetermined distance, and this support supports the central part of a sheet longer than the length of the cassette case. There is an invention in which a paper sheet longer than the cassette case can be stored in the cassette case by supporting it in a bent state. Also, in 1986,
As described in Japanese Patent Application No. 95727, there is an idea in which a container is provided with a mounting plate that supports folded paper sheets in a U-shape and a rail that supports the folded portion of the paper sheets. Furthermore, as described in Japanese Patent Publication No. 62-59008, a rectangular cylindrical second seat support is rotatably connected to the rear end of the flat first seat support. The second sheet support is placed in a horizontal position to support the sheet of paper, and the second sheet support is rotated 180 degrees above the first sheet support to hold the sheet of paper in the U.
There is an invention that allows it to be folded into the shape of a letter.

るため、仕切板としてかなりの厚みを必要とする。Problems to be solved by the invention What is described in Japanese Patent Application Laid-open No. 61-254430 is as follows:
Since the space between the support and the cassette case is narrow, it is troublesome to insert sheets of paper between the support and the cassette case. Also, Utsukai Showa 61-95
In the device described in Publication No. 727, since there is no partition plate that separates the paper sheets folded in half, the weight of the paper sheet acts on the folded portion, causing the folded portion of the paper sheet to have a tendency to bend. There is a risk. Furthermore, the second sheet support described in Japanese Patent Publication No. 62-59008 requires a surface that supports a sheet of paper in a horizontal state and a surface that supports half of a sheet of paper folded into a U-shape. It requires considerable thickness as a board.

。Means for Solving the Problem - A partition plate that faces with a predetermined distance between a cassette case with an opening on the h side and the inner surface of the rear end of the cassette case, and a support portion that supports the partition plate in a substantially horizontal state. and a fulcrum part located on the paper feeding side of the cassette case to hold the partition plate rotatably in a rearward direction.

せて紙葉を容易に折り曲げることができる。By rotating the working partition plate in both directions, a part of the space at the bottom of the cassette case can be opened up, making it easier to insert paper sheets. By later rotating the partition plate downward and bringing it into contact with the support portion, the intermediate portion of the paper sheet can be brought into contact with the rear edge of the partition plate, and the paper sheet can be easily folded.

。Reference numeral 1 denotes a cassette case with an opening on the top surface, and a lid 2 that closes the top opening of this cassette case l has a flap 4 that rotates around a hinge 3 on the paper feed side (left side in FIGS. 1 to 3). have. In addition, the cassette case 1
A bulging portion 6 that bulges downward is formed in the bottom portion 5 near the rear end. Furthermore, a partition plate 10 has attachment pieces 9 located on both sides of the paper feeding side of the curved portion 8 facing with a predetermined distance between the bottom portion 5 and the rear end inner surface 7 of the cassette case l.
is provided. Further, on both sides of the cassette case 1, a side plate 1 is provided which has a fulcrum part 11 that rotatably holds the mounting piece 9 and a support part 12 that supports the partition plate 10 in a substantially horizontal state.
3 is formed. Furthermore, a protruding piece 10a that comes into contact with the rear edge of the sheet 14 is provided on the upper surface of the partition plate IO.

でカセットケース１を複写機等の事務機に装着する。In such a configuration, as shown in FIG. 2, the lid 2 is removed to open the upper surface of the cassette case l, and the partition plate 10 is rotated in the rearward upward direction about the fulcrum part 11. At this time, the partition plate 10 rotates beyond the vertical plane, but the mounting piece 9
Since the corner 9a of the cassette case I contacts the bottom 5 of the cassette case I, it does not rotate any further and maintains a stable state. In this state, since the upper space of the bottom 5 of the cassette case 1 can be widely opened, a sheet 14 longer than the length of the cassette case l can be easily inserted into the bottom 5 of the cassette case l. Subsequently, the partition plate 10 is horizontally rotated about the fulcrum portion 11, and the paper sheet 14 is bent into a U-shape while pressing the center portion of the paper sheet 14 against the curved portion 8 at the rear end. Then, as shown in Fig. 3, the cassette case 1
The cassette case 1 is attached to an office machine such as a copying machine with the top surface of the cassette case 1 closed with a lid 2 and a flap 4 left open.
この状態では、カセットケース１の底部５に支えられた
紙葉１４の先端部が事務機内の給紙口−ラ１５に接触す

ことにより紙葉１４が左方に引き出される。この状態で
は、紙葉１４は折り曲げられた上部半分が仕切板１０に
支えられているため、紙葉１４の自重が外力としてその
折曲部に作用することがなく、しかも、底部５の後端部
には紙葉１４の膨らみを許容する膨出部６が形成されて
いるため、紙葉１４の折曲部に曲げ癖がつくおそれがな
い。この膨出部６は滑らかに湾曲する形状をもって形成
したが、第５図に示すように三角形状に膨出させ、或い
は、第６図に示すように、矩形状に膨出させてもよい。In this state, the leading end of the paper sheet 14 supported by the bottom 5 of the cassette case 1 comes into contact with the paper feed slot 15 in the office machine. Therefore, by driving the paper feed roller 15 clockwise, the paper sheet 14 is pulled out to the left. In this state, the folded upper half of the sheet 14 is supported by the partition plate 10, so the weight of the sheet 14 does not act on the folded portion as an external force, and the rear end of the bottom portion 5 Since the bulge portion 6 that allows the paper sheet 14 to bulge is formed in the portion, there is no fear that the paper sheet 14 will be bent at the bent portion. Although the bulging portion 6 is formed to have a smoothly curved shape, it may be bulged into a triangular shape as shown in FIG. 5, or may be bulged into a rectangular shape as shown in FIG.

a partition plate facing the inner surface of the rear end of the cassette case with a predetermined distance therebetween; a support portion supporting the partition plate in a substantially horizontal state; Since the cassette case is configured with a fulcrum part that holds the cassette case rotatably in an upward rearward direction, the upper space at the bottom of the cassette case can be widened by rotating the partition plate in one direction. Inserting the leaf can be made easier, and by rotating the partition plate downward and making it contact with the support part after inserting the paper sheet, the middle part of the paper sheet can be brought into contact with the rear edge of the partition plate. The paper sheets can be easily folded by touching each other, and by supporting the upper half of the folded paper sheet with a partition plate, the paper sheet's own weight can be prevented from acting as an external force on the folded part. It is possible to prevent the curved portion from becoming bent, and furthermore, since the partition plate simply separates the folded paper sheet into upper and lower parts, it has the advantage of being able to be made thinner.
