Abstract

PURPOSE:To print an original and printed data superposedly without using preprinted paper, negative film or the like by providing an optical array which can control the transmission of light, and controlling the transmission state thereof in accordance with printed data. CONSTITUTION:In the case of superposing an original 15 and printed data DATA and printing the same on paper 19, the light 20 from a light source 17 is irradiated to an original 15 and the reflected light thereof is conducted through the optical element 11 of an optical array 10 on a photosensitive drum 2 and the electrostatic latent image corresponding to the original 15 is formed. On the other hand, light 20 can be transmitted or shielded according to whether voltage is applied on the electrodes 13, 13 of the array 10 or not; therefore, the image corresponding to the data DATA and the image corresponding to the original 15 are formed electrostatically in the synthesized form by applying the printed data DATA on the respective electrodes 13 of the array 10 in synchronization with the rotation of the drum 20.

Description

DETAILED DESCRIPTION OF THE INVENTION α) Technical Field of the Invention The present invention relates to a printing method in an electrophotographic apparatus that allows data to be overlapped with an original.

■ Conventional technology and problems Conventionally, as a method of overlapping the manuscript and 11J y) data, there is a method of overlapping 11J y) data on the manuscript that has already been marked 11 and 19Y top data tg
Is there a known method of printing with a 1mm printing method and a method of printing by overlapping the negative film of the original with a laser beam? Storage space is also an inconvenience due to membership fees.
In the latter case, it is OK to create a negative film of the original.
It had the disadvantage of being time consuming.

・) Circumstances of the invention In order to eliminate the above-mentioned drawbacks, the present invention provides a printing method that allows overlapping printing of original and print data without using paper or negative film. It is a tlI thing to do.

(2) Structure of the Invention In other words, the present invention is capable of controlling the transmission of light and provides an optical array, and also controls the transmission state of the optical playback based on print data, and is passed through the optical array to form a combined image of the document and print data on the sensing drum.
It will be done.

φ) Examples of failures to occur Below, failures will be specifically explained based on examples of failures shown in IQ.

Figure 3 is a diagram showing an example of the nine-electronic photographic scissors holder to which the first wheel support system is applied, @21G is a perspective view showing the optical array, Figure 3 is a diagram showing the operation of the 4R optical element of the optical array, Figure 4 is a diagram showing the operation of the optical array.

The electrophotographic apparatus 1 has one sensing drum 2 as shown in No. 111, and the drum 10 is equipped with a developing device 3, a transfer device S, a collecting tarina, and a charging light T1. A device e and an optical array 10 are provided. In the optical array 10, as shown in the second EK, a large number of optical elements 11 such as liquid crystals are arranged in a row with one glass substrate IL11 in the center of the axis of the drum 20.
A transparent conductor @1S is formed on both the upper and lower sides of the 0-part reference array 1/01 11II upper KFI manuscript 1StII is placed on the mourning manuscript table 1S is provided in the direction of arrow B. 9. Below the meeting 1 @ is the original 61 of Halogen y5yy etc.
17 are provided.

Since the electrophotographic apparatus 1 has the above-mentioned S*t-,
When printing the original 11 and the print date on top of paper 1, place the original 15tS on the original table 1et and transfer the appropriate charge in the directions of arrows A and B, and then move the original 1117 to the original 20t. 1! iKl [is reflected on the surface of the original 1s, and the nine elements 20 are irradiated onto the sensory drum 1 being moved in the direction of arrow C through the optical element 11 of the optical array 1o, and charged by the charger 1. By selectively removing static electricity on the drum 1, an electrostatic latent image corresponding to the original ISK is formed on the drum 1.

On the other hand, each optical element 11 of the optical array 10 can transmit (ON) or block (OFF) the element 20 depending on whether or not 11 voltage is applied to 1 m 13.18 as shown in No. 310 fj. So, array 10's Tsuboden @13% I 5
K71J/)f-IDATAt,, synchronized with 20 rotations of the drum and added in a round shape), each element 11 is selectively 0N10FF for each rotation, and as shown in FIG. 1 data DATAK compatible and good guidance!
Nine images 21 are electrostatically formed in perfect shape, corresponding to the original image 1s.
state and the data is cut off. Therefore, the data 0622 corresponding to the data DATAK is formed on the drum 2, but since the other parts of the array 100 are in the ON state, the data from the original 11 to 0 and 10 is passes through the T-type element 11 to form a cap 21 corresponding to jll15. ).

Therefore, by converting the 0921.12 on the drum 1 into a psi image with toner through the developer 3 and transferring it onto the paper 1, the p% original s and the print data DA are transferred.
A superimposed round image of TA is printed on paper 1-11.

**% Manuscript 15Fi may be in the form of a quantum as in this example, or may be in the form of a sheet. Also manuscript I
Don't be fooled by SO reflections (transmitted light can also be used).

In this embodiment, each collector 11Fi of the optical array 10 is arranged one-dimensionally in the axial direction of the drum 2.
However, it is also possible to arrange it two-dimensionally and make a 9-t vh, and even if element 11 is used, the voltage can be set to 2 @ VrON
J) f
Elements that control t20 can also be used.

- According to the single-shot WsK as described in detail of the invention, the optical array 10
c) The transmission pattern m of ft is controlled based on the bright data DATAK, and the elements 20 from the 15 are passed through the array 10 to form images 21 and 22 on the photosensitive drum 1. Therefore, it is possible to print the original m1llB and the print data DATAO superimposed round printing t1 and draft 1S without using the negative film of the original 15 in the 9 pre-printed paper, saving the storage space of the pre-printed paper and the time to create the film. It becomes possible to provide a printing method that does not require any parts.
