In this document preparation device, read data read from a read object is converted from character data into image data, and the image data is printed by a printer.

[0004]

In the case of the above-described text creating apparatus, the character data and the image data are not stored and managed in the memory, and the contents of the data buffer are erased when the one-way processing is completed. After the character data is converted into the image data and printed, the image data cannot be converted into the character data, so that the mutual conversion between the character data and the image data becomes impossible.

For example, in the case of printing read data after converting it into character data or image data, it is sometimes better to leave the character data as the quality of the database. In addition, since the output device is only a printer and only image data is printed, the quality of a print database cannot be improved.

Alternatively, a display 2 as a display device for displaying image data, and a printer 5 as a printing device for printing character data or image data as a result of image data / character data mutual conversion processing based on the processing contents are provided.

The memory 6 stores image data /
A work buffer 6a showing a work procedure of the character data mutual conversion processing, a management buffer 6e showing a storage management procedure of character data or image data after the image data / character data mutual conversion processing, and a read buffer 6b for temporarily storing read data. And an image data buffer 6c for storing image data in accordance with the work procedure and the storage management procedure, and a character data buffer 6d for storing character data in accordance with the work procedure and the storage management procedure.

The operation of the read data conversion management device (mainly the operation based on the data conversion control device 3) will be specifically described below.

FIG. 2 is a flowchart showing the operation of input data storage processing by the read data conversion management device.

Here, after the scanner 1 reads read data from an object to be read, such as a manuscript, the read data is converted into image data by the data conversion controller 3 to read image data (step S1). The data conversion control device 3 temporarily stores the read data in the read buffer 6b of the memory 6 according to the work procedure of the image data / character data mutual conversion process of the work buffer 6a in the memory 6 (step S2), and then reads the read data into the management buffer 6e. The start and end addresses of the buffer 6b are stored (step S3) (ie,
The processing operation ends when the start and end addresses of the read buffer 6b are written to the management buffer 6e.

FIG. 3 is a flowchart showing an image data / character data mutual conversion operation by the read data conversion management device.

Here, first, the read data read from the object to be read by the scanner 1 is transferred to the data conversion control device 3.
Is displayed on the display 2 (step S1), and the range to be converted to character data on the display screen of the display 2 is designated by the keyboard / mouse 4 (step S2), and it is determined whether or not the range is to be converted to character data (step S2). Step S3)
I do.

As a result, if it is not in the range to be converted to character data (when not converted to character data), the process is terminated. It is converted into data (step S4). Thereafter, it is determined whether or not the conversion was successful (step S5). If the conversion was successful, the character data is stored and stored in the character data buffer 6d (step S8).
However, if the conversion has not been completed, it is determined whether to save the image (step S6).

As a result, when the image data is stored as an image, the processing operation is terminated. When the image data is not stored as an image, character data is inputted by the keyboard / mouse 4 (step S7). Thereafter, the input character data is stored and stored in the character data buffer 6d (step S8).
Then, it is determined whether or not conversion into character data has been completed (step S5).
After that, the address of the character data buffer 6d is stored (step S9), and the processing operation ends.

FIG. 4 is a flowchart showing the data editing processing operation by the read data conversion management device.

Here, it is first determined whether or not the read data read by the data conversion control device 3 is edited as image data (step S1). If the image is to be edited, the image data is read from the image data buffer 6c. Output on the display screen of the display 2 (step S2), edit the image on the display screen (step S3), save the edited image data in the image data buffer 6c (step S4), and end the operation processing. . If not edited as image data, the character data is read from the character data buffer 6d and output on the display screen of the display 2 (step S5).
Then, after the character is edited on the display screen (step S6), the edited character data is stored in the character data buffer 6d (step S7), and the operation process is terminated.

FIG. 5 is a flowchart showing a print data processing operation of processed data by the read data conversion management device.

Here, first, the read data read by the data conversion control device 3 is displayed on the display 2 by the data conversion control device 3 (step S1), and it is determined whether or not to output the processed data (step S2). .

As a result, when the processed data is not output, the read data of the read buffer 6b is output (step S6), and then the operation process is terminated. To specify the range of the data type for the processing data (step S3)
Then, after selecting a data type of image data or character data (step S4), the address of the selected type of data is referred to in the management buffer 6e (step S5), and the corresponding buffer (image data After outputting the corresponding data (image data or character data) from the buffer 6c or the character data buffer 6d) (step S6), the operation process is terminated. The output destination here is the printer 2 as an example, but the same processing can be performed by a file device or the like.

FIG. 6 shows an example of managing the address of the management buffer 6e in the memory 6. FIG. 7 shows one form of data contents as a management example of the management buffer 6e, and FIG. 8 shows another form of data contents as a management example of the management buffer 6e.

Here, in the management buffer 6e, the example 1
Indicates a management method when the handwritten character "A" is read as read data. That is, here, first, in the management buffer 6e, the address 1 (A) is stored in the read buffer 6b as the read data buffer address.
Is stored in the image data buffer 6c as an image buffer address.
If the image data of (A) is stored and the character data is converted to character data and the character code becomes C, the code of C is stored in the character data buffer 6d. At this time, in the management buffer 6e, the address 3 (C) of the character data buffer 6d is stored as the character data buffer address. When character data is selected at the time of output, the management buffer 6e stores the address 3 (C) as an output buffer address.

Example 2 shows a case where image editing is performed from the state of Example 1. That is, when the address 2 (A) is edited as the image data as read and becomes the address 2 (B), the address 2 (B) of the image data buffer 6 c is used as the image data buffer address in the management buffer 6 e. If the character code is stored and the character code is converted to character data D, the character code D is stored in the character data buffer 6d. At this time, the address 3 (D) of the character data buffer 6e is stored in the management buffer 6e as the character data buffer address. When the image data is selected at the time of output, the management buffer 6e outputs the address 2 (B) as the output buffer address.
Is stored.

Example 3 shows a method of managing the management buffer 6e when the graphic E is read. That is, here, the address 4 (E) is stored as the read data buffer address and the image data buffer address in the management buffer 6e and the image data is stored in the image data buffer 6c by reading the figure. In this case, since the figure is read, the process of converting it into character data cannot be performed, and nothing is stored in the character data buffer address in the management buffer 6e. Also, at the time of output, there is only one type of data,
The management buffer 6e stores an address 4 (E) as an output buffer address.

Example 4 shows a case where image editing is performed from the state of Example 3. That is, in this case, if the image data at the address 4 (E) as read is edited and the result is the address 5 (F), the image data at the address 5 (F) is stored in the image buffer 6c. Is shown. At this time, in the management buffer 6e, the address 5 (F) is added to the image data buffer address.
Is stored, but nothing is stored in the character data buffer address as in the case of Example 3. Also, at the time of output, since there is only one type of data, the management buffer 6e stores the address 5 (F) as the output buffer address.

As described above, in the read data conversion management device of the embodiment, the read buffer 6b, the image data buffer 6c and the character data buffer 6d are stored in the memory 6.
Two dedicated buffers are prepared, and once read, the read data is stored in the read buffer 6b without change, and the image data buffer 6c and the character data buffer 6d store image data and character data obtained by converting the read data. Since the data is stored, the data can be output to various devices at any time, and the image data and the character data can be freely processed (edited) according to the management procedure of the management buffer 6e, rewritten, and stored and managed.

[0030]

As described above, according to the present invention, the storage device (memory) is provided with the work buffer indicating the work procedure of the image data / character data mutual conversion process, whereby the character data and the image data are mutually converted. In addition to a dedicated buffer for a read buffer, an image data buffer, and a character data buffer, a type buffer including a management buffer is provided and the management procedure (read,
Since the data is freely processed (edited) in accordance with the address management procedure of various data of images and characters) and stored and managed in a rewritable manner, the quality of the database can be improved in printing and editing. As a result, for example, with respect to one piece of data, a data format can be selected for a part to be partially left as an image and a part to be left as a character,
In addition, if the data amount is to be reduced, the data can be stored in characters, and if the read data is to be faithfully retained, it can be stored in the form of an image. This saves the user the trouble of managing the data format, thereby expanding the usage applications.
