Abstract

PURPOSE:To make it possible to copy using a personal computer equipped with a printer by storing a data signal corresponding to an original picture and outputting it through an input/output means. CONSTITUTION:The light emitting/receiving part 10 and 13 are moved in the direction that intersects orthogonally to the arrayed direction of the light emitting element 9 of a light receiving part 13 that converts the received reflecting light by emitting the light of a light emitting part 10 to an original 8 to an electric signal, with a specified speed against that of the original 8 and the output from the light emitting part 10 is inputted to a control means 2. The discrimination circuit 21 of the means 2 reads out in order the output of an element 9 that is positioned in a line and generates a signal of '1' or '0' according to the strength of the reflecting light and outputs data signals in series. In an address setting circuit 22, the pointer of an address is set up so as to write data signals at prescribed addresses and data signals corresponding to the picture image of the original 8 are written. And by a read out request, the data signals are outputted to an outside equipment 5 through an input/output means 4 and are inputted to a printer 6 directly or through a personal computer 7 and the picture of the original 8 is reproduced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a copying apparatus, and more particularly, to a copying apparatus that reproduces images such as characters and figures on a document onto another copy sheet.

[Background Art 1] Office automation has been proposed in recent years, and personal computers that operate printers have become widespread. On the other hand, there is a demand for copying documents, etc., and copying machines such as PPC copying machines have become widespread. However, both a personal computer and a copying machine are expensive, and purchasing them at the same time would be a huge burden. Furthermore, in conventional copying machines, when making multiple copies from a single original, the original cannot be viewed until all copies are completed, which can be inconvenient.

[Object of the Invention 1] The present invention has been made in view of the above points, and its main purpose is to provide a personal computer equipped with at least a printer.

The purpose is to reduce the cost of copying machines by making it possible to make copies using equipment, and other purposes include:
To provide a copying device which allows a document to be taken out without waiting until all copies are completed when making a large number of copies from one document.

[Disclosure of the Invention] 'Examples) Examples of the present invention will be described below based on the drawings. 1st
As shown in the figure, an image reading means 1 reads images such as characters and figures on a document 8 and converts them into electrical signals, a control means 2 generates a data signal corresponding to the image on the document 8, and a data signal. an external device 5 including at least a printer 6; and an input/output device 4 that reads data signals stored in the storage device 3 via the control device 2 and sends the data signals to the external device 5. It consists of As the external device 5, a personal computer 7 to which a printer 6 is connected, or the printer 6 alone is used. As shown in FIGS. 2 and 3, the image reading means 1 includes a light emitting section 10 that is composed of a number of light emitting elements 9 that emit light onto an original 8, and a light emitting section 10 that emits light onto the original 8 and reflects the light on the original 8. Optical fiber bundle 1 that receives the reflected light
1, and a light-receiving element 12 that converts the light introduced by the optical fiber bundle 11 into a corresponding electric signal.
1 and are arranged on a straight line parallel to each other. The light emitting section 10 and the light receiving section 13 have a width wider than the document in the middle direction of the document, and move at a constant speed with respect to the document 8 in a direction perpendicular to the arrangement direction of the light emitting elements 9. There is. Of course, the light emitting section 10 and the light receiving section 13 may be fixed at fixed positions and the original 8 may be moved. The output of the light receiving section 13 is input to the control means 2. The control means 2 includes a discrimination circuit 21 and an address setting circuit 22. The discrimination circuit 21 sequentially reads out the outputs of the light emitting elements 9 arranged in a row and determines "
1" or "O" signals are created, and these signals are sequentially arranged in series to output a data signal. In order to express intermediate tones, it is necessary to equip the discrimination circuit with a halftone function such as a dither method. Good one.Address setting circuit 2
In step 2, an address pointer is set so that the data signal is written to a predetermined address in the storage means 3 constituted by a random access memory. In this way, a data signal corresponding to the image of the original document 8 is written into the storage means 3. The data signal written in the storage means 3 is outputted to the external device 5 via the input/output means 4 when there is a read request. The external device 5 is provided with at least a printer 6, and the data signal output from the input/output means 4 is inputted to the printer 6 directly or via the personal computer 7, and the image of the original 8 is printed as the printer output on copy paper. It is reproduced above. Here, the transmission line 15 connecting the input/output means 4 and the external device 5 has a variable length, and the device for reading the document 8 and the device for reproducing the document 8 may be placed apart from each other.

[Effects of the Invention] As described above, the present invention includes an image reading means for reading images such as characters and figures on a document, a control means for converting the output of the image reading means into a data signal corresponding to the image, and a control means for reading an image such as a character or a figure on a document. storage means for storing data signals corresponding to the image of h-!; input/output means for outputting the data signals to at least an external device having a printer to reproduce the image of the document on the printer output; and h-! , ji#5-? 1f time, it is possible to make copies if there is a device such as a printer or a personal computer, which has the advantage that the cost required for a copying machine can be reduced. Furthermore, since the data signal corresponding to the image on the original is stored in the storage means, once the image has been read, it is possible to make a copy using the data signal read from the storage means, and one sheet of the original can be copied. This has the advantage that when making a large number of copies from a document, the original can be taken out without waiting until all the copies are completed.
