す不都合が発生する。 Generally, in an electrophotographic copying machine, a toner image formed on a photosensitive drum in a developing section is transferred onto a transfer paper by a transfer charging device in a transfer section. In order to perform this transfer process, a transfer paper guide device is provided to supply the transfer paper to the transfer section, but the conventional transfer paper guide device guides the transfer paper onto the photoreceptor drum 1 as shown in FIG. It has an upper guide plate 2 and a lower guide plate 3 for this purpose. However, the spacing between the upper and lower guide plates is set to match standard paper such as plain paper (basis weight 50 to 65 kg), so when feeding thick paper such as postcards (basis weight 180 to 200 kg), it becomes difficult to run the cardboard smoothly. I'm coming. In addition, if the distance between the upper and lower guide plates is increased in order to make the cardboard run smoothly, when plain paper, etc. is fed, the leading edge of the fed paper will come into contact with the toner image on the photosensitive drum, causing the leading edge of the transfer paper to move smoothly. Inconveniences occur such as toner contamination on the back side and deterioration in the quality of the transferred image.

とである。 The present invention has been made to eliminate the above-mentioned drawbacks of conventional transfer paper guiding devices, and its purpose is to ensure that the transfer paper is always guided smoothly even when the thickness of the transfer paper varies. To provide a transfer paper guide device that allows copies of excellent image quality to be obtained.

かつた。 The present invention will be explained in detail below with reference to the drawings. In FIG. 2, one end of an elastic member 4 for guiding transfer paper is attached to the upper guide plate 2, the other end of the elastic member 4 is in contact with the tip of the lower guide plate 3, and the transfer paper P is elastic. It moves in the direction of the arrow while releasing the contact between the member 4 and the lower guide plate 3. Transfer paper P
The leading end is guided along the leading end of the lower guide plate by the pressure of the elastic member 4, and therefore reaches the predetermined transfer point A without colliding with the photosensitive drum, and satisfactory transfer is performed. The elastic member for guiding the transfer paper is a flexible thin plate, and the tip of the transfer paper is placed upward (downward).
Any material can be used as long as it has enough elasticity to guide along the tips of the guide plates 2 and 3, and can be made of, for example, metal foil, plastic film, or wire bent into a rectangular shape. According to the present invention, it has been found that Mylar (trade name, manufactured by 3M Company) made of polyester film is preferable.
また、第３図は転写紙案内用弾性部材４を下案
内板３に取り付けた実施例を示したもので、この
場合には上案内板の先端部を稍下方に向けておく
のがよい。 Further, FIG. 3 shows an embodiment in which the transfer paper guiding elastic member 4 is attached to the lower guide plate 3. In this case, it is preferable that the tip of the upper guide plate be directed slightly downward.

じることがない。 According to the transfer paper guide device of the present invention, the running state within the guide device changes depending on the interval between the upper and lower guide plates and the type of transfer paper, but the elastic member corrects the direction of the leading edge of the transfer paper so that Since the leading edge of a predetermined transfer paper comes into contact with the photosensitive drum, there is no possibility of contamination of the back surface of the transfer paper or transfer failure.
