響を受け、コピー画質の低Fをきたすことがある。Prior Art For example, cut sheets used in copying machines or microprinters are transfer paper or copy paper for transfer type copying machines, photosensitive paper for electrofax systems, printing paper for simple printing machines, etc., and are susceptible to the effects of outside air and humidity. Paper jams occur when paper supply performance deteriorates. In addition, the image quality deteriorates due to such a reduction in the performance of the cut sheet. Therefore, when not copying, it may be necessary to take the cut sheets out of the paper supply tray and store them in a plastic bag or the like. In addition, with cut notes that have a photosensitive surface such as one coated with zinc oxide, the quality of the copied image may deteriorate due to the effects of temperature and humidity (the upper part of the cut sheet stored in the paper supply tray is affected by external light). It may cause low F.

ってしまう不具合があった。Conventionally, a moisture-proof thin plate with a cutout in the area where the feed roll is located was tightly attached to the paper surface above the cassette in order to block temperature, humidity, and external light. However, since the moisture-proof thin plate is made of vinyl or metal, in high temperature and high humidity conditions, the vinyl or metal surface becomes sticky with water droplets and sticks to the paper on the cassette, causing the paper to not be fed. There was a problem.
発明の目的

湿性薄板を設けた用紙供給皿を提供することを目的とす
る。OBJECTS OF THE INVENTION It is an object of the present invention to overcome the above-mentioned drawbacks and to provide a paper supply tray provided with a moisture-proof thin plate to which water droplets do not adhere.
発明の構成
本発明はビニールや金属などの防湿性材料に紙を貼り合

触するようにして水滴の付着をな(シ、カセット上の用
紙が送られな(なるのを解消したものである。Structure of the Invention The present invention aims to prevent water droplets from adhering to the paper surface of a moisture-proof thin plate made by bonding paper to a moisture-proof material such as vinyl or metal by bringing it into contact with the surface of paper in a supply tray. This solves the issue where the paper on the cassette would not be fed.

PPC用紙を使用できるが、用紙供給皿に供給する用紙
の種類により他の用紙を使用することもできる。積層は

法も可能である。Here, the paper laminated on the moisture-proof material can be general high-quality paper or PPC paper, but other papers can also be used depending on the type of paper to be fed to the paper supply tray. Lamination is usually performed by bonding with an adhesive, but methods such as lamination are also possible.

る最上面の用紙を示している。This supply tray stores paper 2 in a cassette, and is provided with a moisture-proof thin plate 3 on the top of the paper 2, and the moisture-proof thin plate is provided with a notch 4 into which a roller for feeding the paper 2 is inserted. FIG. 2 shows the state when the paper 2 is being pulled out, and 2a indicates the topmost paper that is being pulled out.

不動性であるが、その具体的手段は省略する。In this example, a moisture-proof thin plate 3 made of a moisture-proof material 3a and paper 3b is used in place of the moisture-proof thin plate shown in FIG. The moisture-proof thin plate 3 made of a moisture-proof material 3a and paper 3b sufficiently isolates it from outside air, and prevents moisture from adsorbing on the paper surface 2a in the supply tray. In this case, it is preferable that the paper layer ε of the moisture-proof thin plate 3 be brought into close contact with the surface of the paper 2. Although the moisture-proof thin plate is movable in the vertical direction, it is immovable in the front, rear, left and right directions, but the specific means thereof will be omitted.

0μ aluminum foil metal layer 3a and 100μ thick high quality paper 3b
A moisture-proof thin plate 3 to which was attached with an acrylic resin adhesive was placed on the paper 2a with the high-quality paper 3b facing toward the paper surface. When I left this structure in a room with a relative humidity of 85 degrees for 48 hours and then made copies, I was able to make clear copies with no paper jams from the first sheet. The moisture content of the paper at this time was maintained at around 5 cm, which was the initial moisture content. Also, when I set and fed paper with a moisture content of 8.7% that had been kept in a room with a relative humidity of 85 degrees, no paper jams occurred.

A moisture-proof thin plate made of a 0μ iron foil metal layer 3a and a 80μ thick high-quality paper attached using a polyethylene resin adhesive is attached to the high-quality paper 3.
Place b facing the paper side and cover paper 2. With this structure, the same moisture-proofing effect and runnability as in Example 1 were obtained.

(給紙できなかった。When the comparative papers were left in a stacked state in a room with a relative humidity of 85 cm for 48 hours, the moisture content of the first sheet of paper was about 8 cm. When this laminated paper was fed into a paper supply tray made of a moisture-proof thin plate and a single PVC sheet, a 30% misfeed occurred. Furthermore, I set paper with a moisture content of 8.7% and attempted to feed the paper in the same manner, but at this time all of the paper could not be fed.
