The operation of each embodiment of the present invention will be described below. In the embodiment shown in FIG. 1, first, document data to be registered is inputted from the input section (B) 3. If the input document you want to register is a document that is already written on paper, such as a magazine or literature, the input section (B) 3 is configured by scanning, etc. In some cases, it is configured by the computer or word processor itself.

The document data inputted from the input section (B) 3 is first read into a temporary storage device (same type) of the control section 9 via the bus 7. If the input section (B) 3 has a DMA (direct memory access) function, the transfer control section (A)
8 is activated, the document data is output from the bus 7, and the input section (B
) 3 to the control unit 9 at high speed.

The control unit 9 uses a transfer control unit (A
) 8 and transfers the document data to the screen processing unit 6 via the bus 7 at high speed. In the screen processing section 6, the input section (B) 3
If the input document data is in code format, such as input from a computer, etc., it is converted to dot-bang format, and if it is already in dot-bang format, such as input from a scanner, etc., it is converted. The image is displayed on the display unit 2 without being processed.

The registrant issues instructions for enlarging, reducing, scrolling, rotating, etc. from the input section (A) 1, confirms the input document data, and arranges the format of the document data. The instruction information is sent to the screen processing section 6 via the control section 9, and image processing is performed according to the instruction information. Various image processes in the screen processing unit 6 are executed at high speed to improve the man-machine interface.6 When the confirmation and correction of the document data is completed, the registrant assigns a search key to the document data and registers it. Hereinafter, the search key assignment method 1 document data registration method will be explained with reference to FIG.

As shown in FIG. 2(a), Cb'), an area 202 on the display screen for writing the search key is determined in advance. There are two ways to assign a search key: the registrant assigns the key by hand ((a) in Figure 2), and the key is assigned to a part of the document ((b) in Figure 2). .

In the former case mentioned above in 22, the input of input section (A) 1
When a handwritten memo is written in the display area (202 in FIG. 2(a)), the coordinate value data string corresponding to the handwriting of one handwritten memo is sent to the screen processing unit 6 via the control unit 9, converted to a dot bang, and displayed. Input/display area of section 2 (Figure 2 (a)
) 202: The same place as when inputting) is displayed as an echo.

In the latter case, enter the part you want to use as a search key in the input field (
A) When specified in 1 (for example, specified by a rectangular area), the position information of the area is sent to the control unit 9. In the control section,
Enter the search key along with the location coordinates of the specified area.
The position coordinates of the display area (202 in FIG. 2(b)), transfer instruction information to the input/display area, and enlargement/reduction instruction information according to the size of the input/display area are sent to the screen processing unit 6. . This screen processing section performs processing such as enlarging or reducing the contents of the specified area of the document data to the input/display area based on the instruction information, and transfers the contents, and displays the search key in the input/display area.

When the input of the search key is completed using either of the above two methods, the control unit 9 adds and updates the search key information to the database management table, and transfers the information to the transfer control unit (A
) 8, and the screen shown in FIG. 2(a) appears.

The document data in the text data display area 201 and the search key data in the search key input/display area 202 shown in FIG.
) 8 is restarted, the data read into the control section 9 is sent to the storage conversion section 5, and a request is made for encoding.

In the case of binary images such as ordinary document data, the encoding method is MH (
Modified Huffman (Modified Huffman) encoding, MR (Modified Read) encoding, etc. are used, and in the case of grayscale images and color images, DCT (Discrete Cosine Transform), which is becoming increasingly standardized, is used.

When the encoding is completed, the control unit 9 again switches to the transfer control unit (A).
8 is activated, the encoded data is read out from the storage conversion section 5, and is stored in the storage section 4. During this storage, the document data and search key data are stored in different locations on the storage section 4.

When a searcher makes a search request from the input section (A) 1, the search request is sent to the control section 9, and the control section 2 in FIG.
As shown in 03, the database management table is searched to display a list of search keys.

The transfer control unit (A) 8 is activated and the search key data is sequentially read out from the storage unit 4 to the control unit 9. The search key data read from the storage unit 4 is sent to the storage conversion unit 5 and decrypted, and the decryption result is temporarily transferred to the control unit 9 by activating the transfer control unit (A) 8. After that, it is transferred to the screen processing section 6.

In addition, the series of processes in which document data is read from the storage unit 4, decoded by the storage conversion unit 5, and transferred to the single-screen processing unit 6 must be executed at high speed from the man-machine interface, and the transfer control unit ( A) Transfer speed according to 8, read speed from storage section 4, ? It is necessary to determine the decoding unit of the 5-product converter 5, the decoding time, etc.

The transfer method described above is the simplest method.

If there is a problem with the man-machine interface, it is possible to improve the speed by directly transferring data between devices without going through the control unit 9, or by performing parallel processing to transfer the encoding process and the encoding result to the screen processing unit. There are ways to achieve this.

Next, in another embodiment shown in FIG.
and the bus 10 between the screen processing unit 6 and the transfer control unit (B) 11
This is a device that operates in parallel the process of newly generating a data, reading it from the storage unit 4 and encoding it in the storage conversion unit 5, and the process of transferring the encoding result in the storage conversion unit 5 to the screen processing unit 6. This is particularly effective when the decoding unit in the storage conversion unit 5 is small.

That is, the search key data transferred to the screen processing unit 6 is
A list is displayed in order on the display unit 2 as shown in FIG. 2(c).

- Enter the desired search key from the displayed search keys in the input field (
A) When specified by 1, the control section 9 finds the storage address of the search key and the corresponding document data on the storage section based on the position information, and reads one document data from the storage section 4. The read document data is transferred via the storage/conversion section 51 and the screen processing section 6 in the same manner as the search key data, and is displayed on the display section 2 at high speed.

Note that the single-screen processing unit 6 enlarges or reduces character data at high speed to match the size of the display screen of the display unit 2 and displays the data.

Next, according to FIG. 4, a method of creating document data for one individual by writing a handwritten memo from the input section (A) 1 to the document data input from the input section (B) 3 will be explained.

If the document data A input from the input section (B) 3 has already been stored in the storage section 4 through the above-mentioned registration process, it is read out from the storage section 4 through the above-mentioned search process,
In addition, if it is not registered, the input section 401 (input section (B))
As shown in FIG. 4, the dot pattern data is developed as dot pattern data on the screen memory area 405 in the screen processing section 6, 406, and displayed on the display screen 400 of the display section 2.

In order to create personal document data, the searcher selects display section 2.
On the document data section displayed on the display screen 400 of
By using the same method as when inputting a handwritten memo from the input unit (A) 1, it is possible to speed up the transfer process. In the above-described method for creating personal document data, the document data A may be a handwritten memo input from the input section (A) 1.

Document data A and document data B accumulated as above
When adding or modifying, the document data to be added or modified is read out from the storage unit 4 by the above-described search process. The read document data A and document data B are decoded by the storage conversion section 5 and transferred to separate areas on the screen memory area 405 of the screen processing section 6 as shown in FIG. (40 in Figure 4)
0).

When editing instructions such as addition 5 deletion are given from input section (A) 1,
The instruction information is sent to the screen processing section 6 via the control section, and the contents of document data A or document data B are modified. The correction results are stored in the storage unit 4 in the same manner as described above.

(Effects of the Invention) As described above, according to the present invention, image document data B such as arbitrary handwritten memo input, existing magazines, literature, etc. is written. Coordinate value data corresponding to the handwriting of the handwritten memo is sent to the screen processing section 6 via the control section 9. As shown in FIG. 4, this screen processing section 6 converts handwritten memo data into dot pattern data and develops it in an area 407 separate from the document data A on the screen memory area 405 in the screen processing section 6. , the document data A is echo-displayed on the display unit 2, overlapping it with the document data A (400 in FIG. 4).

The searcher updates the database management table so that document data A and document data B are managed as one document.

Furthermore, if the document data A is unregistered, a search key is assigned in the same manner as the method described above. moreover.

The transfer control unit (A) 8 is activated, and the document data A406 and document data B4O7 in the screen processing unit 6 are transferred to the storage conversion unit 5 and encoded. Encoded document data A
and document data B in separate areas 409.4 on storage unit 4.
10.

Even when the document data from the double-sided processing section 6 is transferred to the storage section 4 via the storage conversion section 5, it is possible to easily add or delete handwritten memos to the search data described above. Furthermore, by using part of the content of handwritten notes or document data from a tablet as a search key, assigning a search key is simplified, which has the advantage of providing a personal document search device with excellent man-machine interface. .
