Abstract

PURPOSE:To prevent generation of wrinkles by using plate-shaped members furnished over and under a transcript sheet while it is in standby within an aux. sheet feeding means, providing by this member a function to shelter the sheet from outside air and seal, and thereby avoiding deformation of the transcript sheet. CONSTITUTION:Plate-shaped members 28, 29 over and under a transport belt 27 are in open condition in the periods when the belt 27 runs, when a transcript sheet is fed on the belt 27 by a feed roll 26, and when the sheet is exhausted to a transport path 19 by another feed roll 30. Under other conditions, the two plate-shaped members are shut to enclose the transcript sheet together with the belt 27 whereon the sheet is placed, and the sheet is thus sheltered from the outside air to ensure that moisture absorbing actions are eliminated. An aux. sheet feeding means sends the transcript sheet with its one side copied back to a switch-back part 32, and the sheet is fed again onto the belt 27 where it is put in standby condition by a feed roll 31 for copying on the other side. At this time, the surfaces for transcription is sheltered from the outside air to ensure that the sheet is prevented possible deformation.

However, if the electronic copying device is used in a high-temperature environment, the moisture content of the initially fed transfer paper is high, so if the humidification unit humidifies the transfer paper that has passed through the fixing unit, an excessive amount of moisture will be released. This often results in adverse effects, such as poor transfer due to a decrease in transfer paper resistance, and paper jams, paper wrinkles, etc. due to a decrease in transfer paper stiffness.

。Means for Solving the Problems In order to solve the problems described in 1., the inventors of the present invention have carefully observed the deforming behavior of transfer paper discharged from the fixing means, and found that When the transfer paper is transported from the fixing means to the image forming means for multiple copies, multiple sheets of transfer paper with low moisture content are stacked on top of each other by the fixing means and remain in the auxiliary paper feeding means while being exposed to the outside air. It was found that while the paper was on standby, moisture was absorbed more rapidly than from the outside air, resulting in uneven absorption on the surface of the rotating paper. and,
It has been found that the deviation in the uniformity and absorption of this water content gives non-uniform expansion and contraction to the wood fibers constituting the transfer paper, causing deformation of the transfer paper. FIG. 1 shows the J I S P81
A4 with a moisture content of 7.9% under the moisture measurement conditions of 11
The plate sample transfer was applied to the uppermost sample paper and approximately in the center when 30 sheets were left on the tray under the environmental conditions of temperature 25℃ and humidity 62%. It shows changes in the moisture content of stacked sample papers. As time passes, the sample at the top rapidly absorbs moisture from the outside air, but the sample at the center only absorbs moisture gradually. This moisture measurement was performed near the center of the sample paper surface, but if we estimate from this result, even if the sample paper was loaded in the center, the moisture content in the surrounding area near the outside air would be lower. It is thought that it contains the same amount of moisture as that loaded on top. It can be inferred from this that there is a portion with a deviation in moisture content on one sheet of paper, and this has an adverse effect on the next copy.

作像手段に給紙するものである。The present invention improves the surface of the transfer paper by adding a function of shielding the transfer paper from the outside air and sealing it by plate-like members disposed above and below the transfer paper while the transfer paper is waiting in the auxiliary paper feeding means. The paper is fed to the next image forming means while preventing deviations in moisture content from occurring.

（ＩＵ減するものである。Function The present invention has the above-mentioned structure, and by blocking the surface of the transferred paper with a low moisture content from the arrangement, uneven moisture absorption is prevented and unnecessary transfer of the transferred paper is achieved. Since deformation is avoided, the incidence of paper jams and paper wrinkles that occur during double-sided copying and even single-sided copying multiple times can be significantly reduced (IU).

値の大なるものである。Effects of the Invention According to the present invention, paper jams, double feeds, paper wrinkles, etc., which are caused by multiple IM copies on two sheets of paper performed by ordinary copying means, can be removed from the transfer paper. It is possible to reduce the based failure to 1.1. The reason for this is that the heat fixing means (forcibly draining the moisture from the transfer paper causes the transfer paper to become susceptible to moisture absorption.
Depending on the conditions in which it is left, each transfer paper may contain moisture1.
In order to prevent the deformation of the paper caused by the deviation from the heat 16, in the present invention, the transfer paper, which is in a state where it easily absorbs moisture, is shielded from the outside air to prevent the moisture content from becoming undesirable.11- Its effects can be demonstrated in various situations, and it is of great industrial value.
