Abstract

PURPOSE:To print a document name and a keyword on the same paper by converting the document name and the character code of the keyword to character pattern data by a character generator. CONSTITUTION:A character output instruction and a print instruction are outputted from a central processing unit 1 to a character code control part 12 and a picture data control part 10. When receiving the print instruction, the picture data control part 10 sends an address for read of picture data to a picture memory 11 and sends a timing signal to the character code control part 12. The character code control part 12 sends a character code address to a document name keyword buffer 13 on a basis of the timing signal. A character generator 14 converts the character code to character pattern data on a basis of the character code from the buffer 13 and the address from a character code address generating part 35. This converted character pattern data and picture data from the picture memory 11 are put one over the other and are printed on the same paper by a printer 16.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a document output device capable of simultaneously outputting a document name and a keyword added to a document when outputting an image of the document.

[Conventional technology]

As a conventional document output device, for example, there is one shown in Fig. 4, which is equipped with a central processing unit 1 that serves as the core of the system and manages and controls the entire system, and a document reading means such as COD, which reads the contents of the original document. An image input device 2 that performs reading and photo-electrical conversion, and an image memory 3 that stores the content read by the device.

In the above configuration, the content of a document or the like is read and captured by the image input device 2, and the image information converted into a digital signal is stored in the image memory 3. The document name and keywords input from the keyboard 4 are added to the desired document in the image memory 3 under the control of the central processing unit 1. The image data with the document name and keyword added is stored in the external storage device 6. When performing a search, by specifying the document name or keyword added to the document to be searched using the keyboard 4, the image data of the specified document is transferred from the external storage device 6 to the image memory 3. This image data is read out from the image memory 3 by the image output device 7 and printed out. The content obtained by this printout is the document itself specified by the document name or keyword, and if you want to print out the document name and keyword, you can use a character output device (not shown) to print the document on the paper. print out on a separate sheet of paper.

[Problem that the invention seeks to solve]

However, with conventional document output devices, it is not possible to print out document image data, document name, keywords, etc. on the same sheet of paper, so it is not only difficult to remember the document name and keywords for the document once output. , there was a problem that required a separate sheet of paper with the document name (or keyword) written on it.

[Means and operations for solving the problem] The present invention has been made in view of the above, and it is possible to simultaneously output the document name and keywords on the paper on which the document is printed. To provide a document output device in which a character code of a keyword is converted into character pattern data by a character generator, and this data and image data of a document are superimposed and printed on the same sheet of paper.

〔Example〕

Hereinafter, the document output device according to the present invention will be explained in detail.

FIG. 1 shows an embodiment of the present invention, and the image output device 7 having the configuration shown in FIG. 4 is the object of the present invention. The image output device 7 according to the present invention includes an image data control unit 10 that receives a print command issued from the central processing unit 1 and generates an address and timing signal for reading out image data; An image memory 11 that outputs image data corresponding to an address signal, a character code control unit 12 that outputs an address corresponding to a document name and a keyword based on a timing signal from the image data control unit 10, and the character code control unit a document name/keyword buffer 13 that outputs the document name and keyword characters corresponding to the address signal output from the address signal 12;
2, a character generator 14 that converts into character pattern data based on the output address, an exclusive OR gate 15 that ORs the respective output signals of the generator 14 and the image memory 11, and image data output from the OR gate 15. It is composed of image data 16 that prints data in which a document name and a keyword are superimposed.

FIG. 2 shows an image data control section 10 and a character code control section 1.
The image data control unit 10, which is a detailed block diagram of No. 3, is as follows.
A command determining unit 21 that determines reception of a print command and generates a start signal, a clock generating unit 22 that generates a clock signal based on the output signal of the command determining unit 21, and calculates an address for reading image data. an image memory address generation section 23 that counts the clock signal output from the clock generation section 22 and outputs a line signal; It is composed of a line number counting section 25 that outputs a signal.

Further, the character code control unit 12 is started by the logical product of the command determination unit 31 which generates an output signal when a character output command is input, the output signal of the command determination unit 21, and the output signal of the command determination unit 31. an AND gate 32 for obtaining a signal;
a clock number counting section 33 that counts the clock signal output from the clock generation section 22; a line number 978 section 34 that counts the line signal output from the clock number counting section 24; a clock number counting section 33;
It is comprised of a line number 978 section 34 and a character code address generation section 35 that generates character code addresses and timing signals based on each of the start signals. A parallel/serial converter 17 is provided to convert the parallel signal output from the character generator 14 into a serial signal and apply it to the OR gate 15.
A parallel-to-serial converter 18 is provided to apply the voltage to the signal 5.

In the above configuration, the general operation will be explained with reference to FIG. First, a character output command and a print command are sent from the central processing unit 1 to the character code control section 12 and the image data control section 10.
are output to each of them. Upon receiving the print command, the image data control section 10 sends an address for reading image data to the image memory 11, and also sends a timing signal to the character code control section 12. Based on the timing signal, the character code control unit 12 sends a character code address to a document name keyword buffer 13 in which character codes of document names and keywords are stored. Based on the character code from the document name keyword buffer 13 and the address from the character code address generator 35, the character generator 14 converts the character code into character pattern data. The converted character pattern data and the image data from the image memory 11 are superimposed by the OR gate 15 and printed on the same paper by the image printer 16.

Next, the detailed operation will be explained based on FIG. 2.

Key in the document name and keyword from the keyboard 4. Next, the central processing unit 1 outputs a print command to the command determining section 21, and outputs a character output command to the command determining section 31. The command determining section 21 generates a start signal upon receiving the print command, and applies it to each of the clock generating section 22 and the image memory address generating section 23. Upon receiving the start signal, the clock generating section 22 generates a clock signal at regular intervals, and the image memory address generating section 23 outputs the image memory address to the image memo January 1. The clock signal outputted from the clock generating section 22 is counted by the clock number counting section 24 to generate a line signal. Furthermore, the number of line signals is 97.
A page signal is created by counting by the eight section 25. In response to an address signal from the image memory address generation section 23, corresponding image data is read out from the image memory 11 in word units. This word-based image data is converted into serial data by a parallel-to-serial converter 18 and then sent to an OR gate 15.

On the other hand, in the character code control section 12, a start signal is generated from the AND gate 32 when both a character output command and a print command are given.

From the time when this start signal is received, the clock number counting section 32 starts counting clock signals, and the line number 978 section 34 starts counting line signals. When each count value reaches the count number of the position where a character is to be output, a control signal is sent from each of the clock number counting section 33 and the line number 978 section 34 to the character code address generation section 35. The character code address generation unit 35 generates the document name and the document name containing the keyword.
The address of the character code is sent to the keyword buffer 13. The document name/keyword buffer 13 sends a character code to the character generator 14 in accordance with this address. The character generator 14 outputs character pattern data for the character code to the parallel-serial converter 17. Parallel/serial converter 17
converts the parallel data in word units into serial data and sends it to the OR gate 15. The character pattern data and the image data are exclusively ORed in the OR gate 15 and sent to the image printer 16.

Note that if it is not desired to print out the document, document name, and keywords at the same time, the character output command need not be applied to the character code control section 12. As a result, the AND gate 32 does not output a start signal, so the character code control section 2 does not operate.

In the embodiment shown in FIG. 1, the document name/keyword buffer and character generator are connected to the image output device 7.
Although an example is shown in which it is provided independently within the interior, a configuration as shown in FIG. 3 may also be adopted.

That is, the bus 40 includes a document name/keyword buffer 13, a character generator 14, and a character pattern memory 41.
It is also possible to connect each of them, and have the central processing unit 1 read the character code of the document name/keyword and write it into the character pattern memory 41.

〔Effect of the invention〕

As explained above, according to the document output device of the present invention, when the count value of the clock signal and the line signal reaches the value corresponding to the position where the characters of the document name/keyword should be output, the document name/keyword buffer is output. Since the character code is read and the character pattern data corresponding to the character code is printed over the image data, the document name and keywords added to the document for search etc. can be printed on the same page along with the actual image. be able to.
