2. Description of the Related Art In an apparatus such as an electrophotographic copying machine that forms a monochrome image, a special sheet such as an OHP film can be used for copying in addition to a commonly used standard size sheet. Such a function is provided. Also, for small paper such as postcards,
There is also used one having a function capable of making a copy. However, as disclosed in, for example, Japanese Patent Application Laid-Open No. 4-337747, in a device of a type in which sheets are held on a transfer drum and color toner images are superposed and transferred, a small sheet such as a postcard is transferred onto the transfer drum. Difficult to support. Therefore, in order to perform copying on a small paper such as a postcard using a color electrophotographic copying machine, for example, as shown in Japanese Utility Model Laid-Open No. 60-49544, a large-sized mount is It is considered to use a means for carrying a small size sheet.

As shown in FIGS. 12 and 13, the small-sized sheet traveling means shown in the above-mentioned conventional example has a plastic holding film 11 arranged at the leading end of a large-sized mount 10 and the film 11 The front end portion is attached to the front end portion of the mount 10 to be integrally configured. Then, the rear end of the film 11 is used as a pressing portion 13 for the paper 14, and the leading end of a small paper is inserted between the mount and the pressing portion so that the paper can be conveyed in the paper conveying path of the electrophotographic copying machine. To
Further, in the mount 10, a frame for positioning the paper is arranged corresponding to the image area of the electrophotographic copying machine so that the small paper 14 can be positioned. Therefore, as shown in FIG.
By providing a means for inserting and holding the leading end of the paper 14 with respect to 0, it is possible to easily perform copying on a small paper by using an electrophotographic copying machine that can copy a paper of a standard size. To be done.

[0004]

However, when a small sheet is supported by using the above-mentioned mount and an attempt is made to make a copy by a color electrophotographic copying machine, for example, the color electronic as shown in FIG. 14 is used. Using the photocopier 40,
There may be a problem that the holding action of the sheet with respect to the transfer drum is not performed in a good state. That is, FIG.
As shown in FIG. 4, with respect to the surface of the transfer drum 43,
The mount 10 that supports the paper 14 is electrostatically and uniformly attached and held. However, the paper 14 whose leading end is held by the mount 10 is not attached to the drum surface integrally with the mount,
The rear end may separate in a free state. Then, with the rear end of the sheet 14 kept away from the drum surface,
When the transfer drum 43 is rotated, the edge of the paper 14 comes into contact with other members around the drum, causing a problem that the color toner image is disturbed.

In the color electrophotographic copying machine 40 shown in FIG. 14, in order to supply the sheet to the transfer drum 43, the sheet aligning device 41 causes the sheet to align and the registration roller device 42 causes the sheet to move. In the state where the leading end of the sheet is positioned, the sheet is sent toward the transfer drum 43. Further, a charging corotron 45 is arranged inside the transfer drum 43, and in addition to the function of pressing the paper against the surface of the drum by the pressing roller 44, the function of electrostatically supporting the mount 10 is exhibited. The photoconductor drum 50 is arranged corresponding to the transfer drum,
A charging corotron 51, a cleaning device 52, and a developing device 53 for forming toner images of a plurality of colors are arranged around the photosensitive drum. The developing device 53
, Four-color developing devices y, m, c, and b are arranged, and the developing devices corresponding to the colors to be developed are moved to the developing portion of the photosensitive drum to form a color toner image on the photosensitive drum. After that, the color toner image is transferred to the paper carried on the transfer drum by the discharge of the transfer corotron 46. Then, after the color toner images of a plurality of colors are superposed and transferred onto the paper, the mount 1 carrying the paper is carried.
0 is peeled from the drum by the peeling claw 47, and the fixing device 54
Then, fix it with the fixing device and discharge the color copy.

However, when a color electrophotographic copying machine as shown in FIG. 14 is used to make a color copy on a small sheet, as described above, the sheet holding action is performed well. The problem of not being discouraged remains. Therefore, for example, as shown in FIG. 15, when the paper P such as a postcard is supported on the backing sheet 20, diagonal insertion slits 21 to 24 are formed so as to insert the four corner portions of the postcard. Means for providing and supporting may be considered. In the mount 20 shown in FIG. 16, the position for supporting the paper is set according to the size of the postcard P, and the width B of the paper is set.
The distances a and A are set on the front and side portions of the mount 20 in correspondence with the length b and the image transfer position on the paper P can be easily set.

However, when using the mount having the above-mentioned structure, for example, as shown in FIG.
A mechanism for supporting only one sheet of paper on the side of the mount, and the roller member in the paper separating device of the electrophotographic copying machine is positioned in the separating part 26, the mount easily passes through the paper separating device. it can. On the other hand, as shown in FIG. 17, when two sheets of paper P1 and P2 are supported on the mount 20 and an attempt is made to pass the portion of the paper separating roller 46 of the paper feeding device, the mount 20 is supported by the mount. The part of the paper P2 that
The roller of the paper separating device exhibits an action of blocking passage of the leading end of the paper P2. Then, since the action of peeling the sheet from the mount may occur and the sheet P2 may be separated, the mount cannot normally pass through the part of the paper separating device.

Therefore, in order to solve the above-mentioned problems, as shown in FIG. 18, it is conceivable to construct a holding means by the adhesive portions 31 and 32 in order to hold the paper on the mount. . In the example shown in FIG. 18, the adhesive portions are arranged on the paper support surface of the mount 30 in correspondence with the lengths of the small papers P and P1, respectively, and the leading end and the rear end of the paper are mounted on the mount. The adhesive holding makes it possible to prevent the paper from peeling off from the mount when passing through the paper separating device. However, when the above-mentioned paper holding means is used, when the paper is held on the transfer drum, or when guiding the curved path, the paper and the paper are integrated as shown in FIG. There is a problem that is not retained in. In other words, when the above-mentioned paper is made of a paper having a high rigidity such as a postcard, and the mount 30 is made of a paper such as a plain paper, the strength of the waist of the two members is different, so Wrinkles may occur. If the member that holds the paper in a bent state is the transfer drum, the paper P is not evenly attached to the surface of the drum, so that the image transfer function is not performed well and a defective copy is created. There is a problem.

Further, as described above, instead of using a means for carrying paper such as a postcard on the mount, as shown in Japanese Patent Laid-Open No. 4-42182, the auxiliary sheet is replaced by a small paper. It is also conceivable to attach and copy. However, when the auxiliary sheet shown in the conventional example is used, it is effectively used when a mechanism for nipping and holding the leading end of the paper is provided for the transfer drum. The problem remains that it cannot be easily applied with a device that electrostatically holds paper. further,
When the sheet holding means as shown in FIG. 17 or FIG. 18 is used, when the backing sheet passes through the section of the sheet sorting apparatus, the sheet is likely to be obliquely fed due to the sorting action on the sheet. There is a problem that the quality of the copy is deteriorated.
