給紙するタイプの電子写真複写機に於ける供給用紙の調
湿技術に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a technique for controlling the humidity of supplied paper in a paper-fed electrophotographic copying machine.
電子写真プロセスに於ける静電転写方式では、’IR

転写を行っている。したがって、転写紙が吸湿して導電
状態にあると必要な電荷を確保することができず、転写
紙の電界が弱くて良好な転πが行ねノ],ない。In the electrostatic transfer method in the electrophotographic process, 'IR
The image is transferred by applying a charge of opposite polarity to the toner image to the paper. Therefore, if the transfer paper absorbs moisture and becomes conductive, it will not be possible to secure the necessary charge, and the transfer will fail. Because the electric field of the paper is weak, good π rotation cannot be achieved.

た。Therefore, conventional paper feed cassettes have been used that have completely open tops, or that allow air to circulate freely between the inside and outside even when the lid is closed. Therefore, during the rainy season A. (r) When the relative humidity of the outside air was high, the claws inside the paper feed cassette absorbed lIσ air and became in a state of high moisture content, making it easy for copies to drop out due to poor transfer.

ようと1−る点にある。The present invention relates to an improvement of the prior art, which was devised in consideration of such circumstances, and involves blowing dehumidified air using a desiccant onto the supplied paper (=J, then t;+rfl of the paper). The purpose of this is to always make a stable and high-quality copy of the outside air, regardless of what it is.
以下、図面に則して本発明をlR’+明する。The present invention will be explained below with reference to the drawings.

Therefore, when the paper cassette 1 is stored in the storage position when not in use, the 11T i2B can be closed and the paper P inside can be protected from atmospheric moisture to some extent. is possible. When using the paper feed cassette 1 by loading it into the paper feed section of a copying machine, as shown in the figure, 11.
Open ``1-ru''.

る。On the other hand, the copying machine is equipped with a dehumidified air supply device 3, and the device 3 is equipped with a desiccant 6', such as linica gel, chloride, etc. i: A filled container 5, a blower 4 connected to the container 5, one end connected to the container 5, the other end 6
A is made up of a blowing pipe 7 which is arranged so as to face the paper P in the paper feed cassette 1 loaded in the paper feed section.

The paper P in the paper feed cassette 1 is blown 4q through the air pipe 7 with a wire. This ejected air A passes through the inside of the container 5'1
Since the paper P is dehumidified by the desiccant 6 during this period and is in a low humidity state, the paper P is effectively dehumidified even if the paper P is in a moisture-absorbing state. Note that air A is supplied from paper feed cassette 1.
The first jet is ejected onto the exit side surface of the paper P inside. In addition, dehumidification is carried out over the entire surface of the paper L that enters the inside of the paper feed cassette 1, and while the paper P is being carried out, the entire surface from the front end to the rear end is dehumidified. Since direct injection is performed sequentially, uneven dehumidification does not occur.

される。In addition, if dry air is blown not only at the paper feed section but also at the entire conveyance path up to the transfer section, it is possible to prevent the dehumidified paper from re-absorbing moisture and to ensure stability. guaranteed transcription.
なお、半密閉型の給紙カセットを用いた場合には・待機
保管位置にある給紙カセット内に常時乾燥空気を供給す
ることができ、用紙の調剤を略ぼ完全に実行し得る。Note that when a semi-closed type paper feed cassette is used, dry air can be constantly supplied into the paper feed cassette in the standby storage position, and the dispensing of paper can be carried out almost completely.

For example, there is no need to equip a dedicated dehumidifying fan or blower, and the production cost can be reduced to 11%.

It can be as low as 1-. Therefore, is a stable transcription always guaranteed nine good quality copies? I can do 1 thing.
