According to the present invention, original contents to be copied from a digital copy machine can be downloaded and stored on a digital data recording medium such as a floppy diskette or flash memory for playback on a computer or caption player, and the original digital data stored on the data recording medium can be easily reproduced. The present invention relates to a digital copy machine provided with a document content recording and reproducing means which can be output to paper through a copy machine.

A general digital copier can store the original image information read through the scanner in the image data memory, and enlarge or reduce or copy as many copies as desired according to the copy function selection and condition setting.

Fig. 1 shows a schematic circuit block configuration of a digital copier. The digital copier has a scanner 13 that reads the contents of an original as digital data, and a memory 12 that stores digital data read by the scanner. And a developing unit 15 which charges the digital data stored in the memory to a drum and transfers it to copy paper, a function selection and condition setting unit 11 for setting a digital copy mode and copy conditions according to a user's key input, and digital It consists of a system controller 10 that controls the overall operation of the copier.

When such a digital copier reads the document 14 placed on the contact glass or the document passing through the automatic document feeder ADF, the scanner 13 generates image data, and the image data is temporarily stored in the memory 12.

The system controller 10 then sends the image data of the original stored in the memory 12 to the developing unit 15 according to the copying conditions registered in the function selection and condition setting unit 11. In the developing apparatus, an image electrostatic latent image of the contents of the original through charging is formed on the drum, and then the copying operation is completed by fixing and discharging it on the copy paper 16.

Such a copying operation using a digital copying machine is very advantageous compared to a general copying machine when one original is reduced or enlarged or a large quantity is copied in its original size. In the case of non-digital copiers, if one copy of a large number of originals is required, the carriage having the exposure device and the scanner must be repeatedly moved by the copy quantity, which will result in shortening the mechanical life of the copier and prolonging the copy time. .

On the other hand, the copy output for the original is paper, whether the copier is a digital type or not. Therefore, when a large amount of originals are copied, the result may be inconvenient for storage and transportation even if the result is paper.

In particular, in the light of the trend that all information is digitized and processed throughout the entire society such as political economy, social culture, etc., copiers using copy paper as their output should make their own progress to meet the information age.

It is an object of the present invention to download original contents to be copied from a digital copy machine onto a data recording medium such as a floppy diskette or flash memory, which can be reproduced by a general computer or a caption player, and also to simply copy the original data stored on the data recording medium. The present invention provides an advanced digital copier that can exchange information with other digital information processing means by outputting through paper.

The present invention for achieving the above object is a scanner for reading the contents of the document as digital data, a memory for storing the digital data read by the scanner, and the digital data stored in the memory to the drum to transfer to copy paper A digital copier comprising a developing device, comprising: a data interface device for extracting original content digital data stored in the memory to the outside and transferring original content digital data to the memory; Between the digital copier and another digital data processing device by adding an original content read / write device for storing the original content digital data on a recording medium and reading and transmitting the original content digital data stored on the recording medium to the data interface device. Digital It is characterized in that the exchange of data can be made.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

Fig. 2 shows a circuit block diagram of a digital copy machine provided with a document content recording and reproducing means of the present invention. As referred to herein, the digital copier of the present invention includes a scanner 13 for reading the contents of an original as digital data, a memory 12 for storing digital data read by the scanner, and a document stored in the memory. A data interface device 17 which draws out content digital data to the outside and transmits the content digital data input from the outside to the memory; and stores the content digital data drawn out by the data interface device on a recording medium; An original content read / write device 18 for reading the original content digital data stored in the recording medium and transmitting the original content digital data to the data interface device, a developer 15 for charging the drum with digital data stored in the memory, Setting the digital copy mode and copy conditions according to the user's key input And a selection and tank construction unit 11, a system controller 10 that controls the entire operation of the digital copying machine.

Such a digital copier generates a digital data by the scanner 13 reading an original 14 placed on a contact glass or an original passing through an automatic document feeder, and the digital data is temporarily stored in the memory 12.

Digital document content data stored in the memory 12 is read / written through the data interface device 17 under the control of the system controller 10 according to the user's function selection and operation of the condition setting unit 11.
