Abstract

PURPOSE:To eliminate the need for a device dedicated to data imprinting operation by using a light emitting array to discharge a photosensitive body and also imprint data. CONSTITUTION:When the photosensitive drum rotates, all LEDs of the interimage and image end eraser; unit 200 consisting of the LED array forming a data imprinting device 17 are turned on to remove interimage and image end chargers of the photosensitive drum. Then, when the photosensitive drum rotates up to one terminal a1 of an area IC shielded by a shutter 210 to image exposure, LEDs corresponding to the image end of the unit 100 and a data imprinted area ID are turned on and others are turned off to remove charges at the image end part of the photosensitive drum and also imprint data in the area ID. Consequently, the dedicated imprinting device is unnecessary and the data imprinting operation is carried out through the simple constitution.

At step 50'7, the light emitting diode G (the light emitting diode 731 which turns off at step 8508 and indicates that imprint mode 2 has been selected) lights up. Then, in step 5515, the image of the already set copying magnification data is inverted, and photoconductor 1! In step 8516, this inverted data is converted into data that can be written into the RAM latent image -1-.
:'4 is stored in a predetermined storage area. Data imprint mode switch A 3 is 3 (iil, because imprint mode 2 is selected in 21ii+11)! Then, the input mode () in which data is not input is set, and the light emitting diode 73) is turned off in step Sr.10. When this imprint mode is 1S0, the light emitting diode 73a, ? Neither 31+ lights up. FIG. 21 shows a detailed 70-channel diagram of the image area display routine. In this image area display routine, the closeness of the image on the photoreceptor drum is calculated based on the size of the document and the close-up rate (1), and the length and width are calculated using the image length display discovery diode 7.

If the data is larger than 42 fl Iom, the data in memory Q10 is changed to the maximum length of 42 () This data is output as data for displaying the image length. Various methods for detecting the size of the original are already in use, so they will not be explained in particular. This can be done automatically according to the measurement result of the image area, or the image area may simply be made to match the size of the copy paper to be used. This is a flowchart showing a detailed flowchart. When it is determined that the imprint mode is other than 0 in step S9t), that is, when imprinting data from jIif et al. Step S9 o

Set it on the axis counter. This is a process to prevent the imprint position DA shown in FIG. 6 from being mistakenly set outside the range in the right direction of the paper length while repeatedly pressing the imprint position setting key 700. Furthermore, in steps 8906 to 5909, the X-axis counter is decremented every time the ON edge of the imprint position setting key 701 occurs, and the count value of the X-pongee counter is ().
If it is determined that it is smaller, 0 is again set in the x pongee counter. This is a process for 7) preventing the indentation position DA from being mistakenly set outside the range in the left direction of the paper length.

When the paper is cut, this paper width is set again on the Y pongee counter. This is a process to prevent fj'r (I) "sinking position l) A shown in Figure 1 from being mistakenly set outside the downward range of the paper width. Furthermore, in steps 8915 to 8918, Imprint position setting key 70
Every time an ON edge of 3 occurs, the Y-axis counter is decremented, and if the count value of the Y-tsumugi counter is determined to be smaller than J, () is set in the 'tsumugi counter again. This is a process to prevent the imprint position DA from being mistakenly set outside the upper range of the paper width. Then, in step S919, the count value of the Y-axis counter is outputted as Y-axis imprinting position display data, and the ''-axis imprinting position display light emitting diode 721 is caused to emit light in accordance with this data. Then, in step S92o, the optical path shutter 210 is moved in accordance with the data imprint position 16 set by the above-described process. Although the details of this process will not be explained, the movement of the optical path shutter can be controlled by, for example, a mechanism consisting of a rack and pinion. Generally speaking, if the 11th feed of copy paper (formation of a copy image) is based on one side, the position of the data imprinting mechanism can be fixed as far as the reference side is concerned, whereas in a copying machine where the copy paper is based on the center. In this case, the data imprinting position must be moved depending on the paper size (or image size). Therefore, this imprint position setting routine allows data to be imprinted at the edge of the image even with a center-based copier, and the imprint position is displayed, so you can select an appropriate place in the copied image and imprint. can. Further, if the copying machine is a one-sided copying machine, this imprinting position 1n setting routine is not necessary unless the data imprinting position is changed.

Set 2. The internal timer 131 measures the time it takes for the photosensitive drum to rotate by the rotation angle a (FIG. 11) of the photosensitive 11ζ tram, which determines the width of the dont of imprint data. The timer D2 sets the timing at which the optical path shutter operates for a total of 11 times. Step S7] When the timer D2 completes a total of 0, 'r at 2,5713, power is applied to the Nyatta sole/id to turn on the optical path!

Effects - 4 - 1 - As explained in the present invention, Since the image-to-image and image-edge erasers are constructed from light-emitting element arrays17, and data is imprinted using a portion of this light-emitting element array, a dedicated device for data imprinting is not required, and duplication ( In addition to being able to reduce the cost of 1, it is also possible to imprint data on the light-emitting element array. Since it is possible to arbitrarily select the light-emitting element and set the position at which the insertion is performed, the formation of the copied image can be easily performed.
