Abstract

PURPOSE:To confirm copy contents to perform the image processing before outputting a copy, by storing the optical image of an object to be copied in a storage device and reading out its contents by a reading means and printing them by a printing means. CONSTITUTION:The image of an object 11 to be copied is transmitted to a photoelectric converting part 18 through an optical system 14 and is converted to an electric signal. This signal is converted to a digital signal by AD conversion and is stored in a storage circuit 20. When the object 11 is copied, contents of the storage circuit 20 are read out by a reading part 21, and the signal is printed in a printing part 22 to obtain a copy 13; and when the operator wants to confirm copy contents, contents of the storage circuit 20 are read out by the reading part 21 and are displayed on a display such as a CRT. Consequently, copy contents are confirmed before outputting the copy 13, and thus, the failure of copy is prevented to make the copy work efficient.

Description

[Detailed description of the invention] The present invention relates to electronic copying machines.

FIG. 1 is a pull diagram of an example of a conventional electronic copying machine. 1 is an object to be copied, 2 is a copying machine main body, and 3 is a copy. The copying machine main body 2 includes an optical system 4, an exposure section 5, a developing section 6, and a fixing section 7.

The operation of a conventional electronic copying machine will be explained below with reference to FIG. The image of the object to be copied 1 is transmitted to the exposure section 5 through the optical system 4. The exposure section 5 forms the transmitted image of the copying object 1 on a copying medium, the developing section 5 develops the image, the fixing section 6 fixes the image, and finally the copy 3 is output.

Therefore, the image of the object to be copied is formed directly onto the copying medium, and the quality of the copy is determined by the experience and feeling of the operator. Ta.

Also, it is not possible to know whether the copy was successful until the copy is finally output from the copying machine, so if you copy the same thing over and over again, you will often find yourself repeating the same thing over and over again.

The present invention eliminates these drawbacks of the conventional copying machine and provides a copying machine that allows the user to confirm the content of the copy and perform image processing on the content before outputting the copy.

According to the present invention, the present invention is characterized in that it includes a storage device for storing an optical image of the object to be copied, a reading device for reading out the stored contents of the storage device, and a printing device for printing the output of the continuous printing device. An electronic copying machine is obtained.

FIG. 2 is a block diagram of an embodiment of an electronic copying machine according to the present invention. 11 is the object to be copied, 12 is the copying machine body, 1
3 is a copy. The copying machine main body 12 includes an optical system 14, a photoelectric conversion section 18, a colleague processing section 19, a storage circuit 20, and a reading section 21.
, printing section 22).

The operation of electronic copying according to the present invention will be explained below with reference to FIG. The image of the object to be copied 11 is transmitted to the photoelectric conversion section 18 through the optical system 14, and is converted into an electrical signal in the photoelectric conversion section 18. The image signal converted into an electric signal by the photoelectric conversion section 18 is subjected to AD conversion, and the image signal converted into a digital signal is stored in the storage circuit 20. If the operator wants to check the contents of the copy before outputting the copy, this can be done by displaying the contents of the memory circuit 20 on a CRT-like display device using the reading section 21. When a copy is to be made, the content of the memory circuit 20 is read out by the output unit 21 and the signal thereof is printed out by the printing unit 22.

Therefore, when making a copy using the electronic copying machine according to the present invention, the contents of the memory circuit in the image processing section are read out,
It will be printed. Furthermore, before outputting a copy, the content to be copied can be confirmed by reading out the contents of the storage circuit of the image processing section and displaying it on a display device such as a CRT.

In addition to changing the contents of the memory circuit, it is also possible to modify the contents of the copy.

The electronic copying machine according to the present invention can eliminate copying failures and improve the efficiency of copying operations, and has great practical value.
