Similarly, when distributing only to companies ranked A rank (for example, companies A and B), the second selection key (7b) for A rank distribution is pressed. Copy paper (11) only in the trays (68) of Company A and Company B

In addition, the LED array (15) is G a A s P
(7) It is composed of a group of red LEDs formed by mounting GaAS on the heath, and the emission wavelength is approximately 6,600. Therefore, photoreceptors suitable for this purpose are limited to amorphous silicon having long wavelength characteristics, selenium with a high tellurium content of 1, and the like. In this point,
When a green LED array (wavelength: 5650) is used, the range of types of photoreceptors that can be used with it is expanded.

In Figure 7, TC is the conjugate length and zo is the lens (14)
The length 10 represents the distance from the end surface of the lens (14) to the LED array (15) or photosensitive drum (13). The relationship between these dimensions and the wavelength of the LED is shown in the following table.

The same short focus lens row can be used for the D array and the halogen lamp, but the length of the lenses used must be different for the red LED array and the halogen lamp, so the same short focus lens row (14) cannot be used.

In the state shown in FIG. 12(A), the holder (44) is located above the portion of the photoconductor where the latent image 1 (black) is formed, so that the document image in that portion is 'CDJ is not projected and imaged onto the photoreceptor drum (13). Therefore,
An image other than the original image formed by the original image ``ABJ'' and the LED array (15) is formed as an electrostatic latent image. On the other hand, in the state shown in FIG. 12(B), the LE
Since the D array (15) does not exist on the short focus lens row (14), all the original images "ABJrCD" are projected and formed on the photosensitive drum (13), but the electrostatic charge other than the original image FIG. 6 is a perspective view showing an embodiment in which only an original image can be projected onto a photoreceptor drum (13) without moving the latent image in the direction of the rotational axis of the forming drum (13). In this embodiment, the holder (44) is constructed so that it can be opened and closed at the upper end, and when forming an image other than the original image "Gyokuyo", the LED Ashii (15)

Further, by moving the holder (44) to an appropriate position, an electrostatic latent image other than the original image can be formed at a desired position. In this case, the photosensitive drum (13) can be rotated. Furthermore, if only the holder (44) is allowed to move without rotating the photosensitive drum (13), it is possible to form an image other than the original image in the direction perpendicular to the moving direction of copy paper = 21-(11). .

In this figure, (21a) is a magnet roller for forming an original image, and (21b) is a magnetic roller for forming images other than the original image. When such a developing device (19) is used, the original image is copied in black on the copy paper (11) J-, and images other than the original image, such as the date, are printed in a color other than black (for example, brown). It turns out.

In this embodiment, since it is difficult to move the part containing brown toner parallel to the rotational axis of the photoreceptor drum (13), the position where images other than the brown original image are formed is moved. It's hard to forgive.

When printing with an LED array in a printer or the like, a black print is usually formed only on the portion corresponding to the light emitting part of the LED by performing reversal development. However, in the case of an electronic copying machine, if the reversal development is performed, the black and white of the original image will also be reversed, which causes a problem. Therefore, in the case of the present invention, when forming white characters, etc., the LED array can be made to emit light corresponding to the characters. , FIG. 22(D) shows an example in which the LED array is moved and a postal code is printed horizontally in the center.

Claims (1)

[Claims] 1. The original image is projected onto the uniformly charged surface of the photoreceptor to form a static latent image, and this electrostatic latent image is developed with toner. - In an electronic copying machine configured so that an image is transferred to a copy paper and the copy paper is sent toward a sorter, an electrostatic latent image of an image other than the original image is formed on the photoreceptor. means for forming the electrostatic latent image, means for developing the electrostatic latent image with toner, means for transferring a toner image other than the original image onto copy paper, and storing the copy paper on which the toner image is formed. An electronic copying machine characterized in that the electronic copying machine is equipped with a selection means for selecting a tray of the sorter to be sorted, and the operation of the sorter is controlled by a signal outputted by the selection means. 2. A key manual means provided on the copying machine main body. The electronic copying machine according to claim 1, wherein the tray of the sorter is selected according to the method of the present invention. 1-3. Means for reading a toner image other than the original image transferred onto the copy paper is provided, and An electronic copying machine according to claim 1 or 2, wherein a sorter tray is selected according to the content of the image.
