Abstract

PURPOSE:To prevent the breakdown of already written information by displaying the contents of the change of classification information when the classification information of the previously outputted stored information is changed. CONSTITUTION:When the stored information in different types stored into a storing means 13 is collectively outputted, the classification information of the stored information attached to the stored information to be outputted by a discriminating means is discriminated, and based on the discrimination result of the discriminating means, whether or not the classification information of the previously outputted stored information has been changed is discriminated by a comparing means. When the change of the classification information is decided, the contents of the change of the classification information is displayed on a display means 24. Thus even when the plural pieces of the information in different processing units or in different attributes are collectively outputted and written to the storing means 13 in a mixed state, the breakdown of the already written information can be prevented.

Description

[Detailed Description of the Invention] [Object of the Invention (Industrial Application Field) This invention relates to, for example, an electronic filing device,
In particular, the present invention relates to an information retrieval device that can integrate and manage image data and code data using an optical disc.

(Prior Art) In this type of information retrieval device, for example, code data in units of files created on a personal computer and code data in units of volumes stored in a storage medium such as a floppy disk are also searched according to their attributes. It is said that it is possible to store and manage data on an optical disk in bulk according to processing units. Here, the attribute refers to the type of data such as image data or code data, and the processing unit refers to the unit of data processing such as file unit or volume unit.

By the way, in this type of information retrieval device, data stored on an optical disk with different attributes or processing units is retrieved, and data with different attributes or processing units is stored in an external storage medium such as a floppy disk, for example. It is possible to output all at once. However, this batch output processing outputs data to an external storage medium without determining the attributes or processing units of the data to be output.

For this reason, for example, even though the processing unit of data to be output has changed from a file unit to a volume unit, the operator does not notice this and ends up overwriting the necessary data that was written earlier. In some cases, data may be destroyed.

(Problems to be Solved by the Invention) This invention solves the problem that when a mixture of data with different processing units and attributes is extracted and stored on a storage medium, the data that has already been written may be destroyed. The purpose is to solve the problem of data that has already been written, even when data with different processing units and attributes are mixed and extracted and stored on a storage medium. The purpose is to provide an information retrieval device that can prevent destruction.

[Structure of the Invention] (Means for Solving the Problems) This invention provides a storage means for storing different types of storage information, and storage information to be output when outputting the storage information from the storage means at once. A determining means for determining type information indicating the type of stored information attached to the stored information, and comparing whether or not the determination result of this determining means is the same as the type information of stored information output immediately before the stored information. and display means that displays the content of the change in the type information when the type information is determined to be different by the comparison means.

(Operation) When outputting different types of storage information stored in a storage means in a batch, this invention determines the type information of the storage information attached to the storage information to be outputted by the determination means. Then, based on the determination result of the determination means, the comparison means determines whether or not the type information of the stored information output immediately before has changed. If it is determined that the type information has changed, the content of the change in the type information is determined by the comparison means. By displaying on the display means, it is possible to display information with different processing units and attributes in a mixed state.
- Even when extracting the information and writing it into the storage means, it is possible to prevent the information already written from being destroyed.

Next, how image data and code data are managed in a unified manner will be explained from the viewpoint of document management.

In other words, the document management system in this embodiment has four parts: cabinet, binder, document, and page, as shown in Figure 2.
It has a hierarchy, and each cabinet is associated with one side of the optical disc 19. Up to 8 binders can be defined in a network, and up to 30,000 binders can be defined in a binder.
You can register up to 0 documents. Each document has a title, and its structure is defined for each binder. The above document is the basic unit of a file, and in addition to the title, annotations (explanation of the document) can be added. Further, a document is composed of up to 4095 pages.

This kind of management system takes into account consistency with paper files, and a page corresponds to one paper file, and this information processing device also manages code data at the level of this page. It has become.

That is, the page is either image data for one sheet of paper, data for one floppy disk (volume-batch data), one file data, or data that is a combination of the above three types.

As a result, for example, as the first page in one document,
Source files of a given program (code data)
, the second page shows the program specifications (code data) created with a word processor, and the third page shows the processing results (image data). Can be managed effectively.

All the image data and code data stored on the optical disk are composed of a header section HD and a data section DT, as shown in FIG. The header section HD stores attribute information AD that identifies whether it is image data or code data, and if the pig is code data, processing unit information UD that identifies whether it is in file units or volume units. is memorized. Similar information is also set for the merged data.

In the above configuration, referring to FIG. 4, documents containing a mixture of image tags, code data in file units, and code data in polygon units are searched from the optical disk 19, and are stored all at once on the floppy disk 28a as an external storage medium. When performing batch output processing, the data to be output is read from the optical disk 19 by a well-known search process,
This data is stored in the main memory 13 via the optical disk device 22 and the interface circuit 17. CPU
12, the attribute information AD of this data is determined by examining the header HD of this read data (S
TI).

As a result, if the data retrieved from the optical disk 19 is image data, output to the floppy disk 28a is inappropriate, so a message and confirmation indicating that output to the floppy disk 28a cannot be displayed is displayed on the CRT display 24. A message prompting you to respond will be displayed (
Sr1). In this state, the operator
Alternatively, by confirming with the mouse 29 (Sr1
), output processing of this image data to the floppy disk 28a is not executed. Then, it is determined whether processing of all documents specified as output targets has been completed (Sr1
), if it has not finished, processing of the next data is executed.

On the other hand, if it is determined in step STI that the retrieved data is code data, the processing unit information UD of the header HD is determined (Sr1). As a result, in the case of file-based information data, whether or not the attribute of the data for which output processing was executed immediately before was code data and the processing unit was file unit, that is, whether the attribute or processing unit has changed. It is determined (Sr6). Then, if there are no changes in the data attributes and processing units,
The output process for the floppy disk 28a is then executed (Sr1). The contents of the header HD of this outputted information are stored, for example, in the main memory 13, and the contents are updated every time the information is outputted.

Further, if it is determined in step ST6 that there has been a change in the data attribute or processing unit, a message indicating that the data attribute has changed to code data or that the processing unit has changed to file unit is sent. ,CR
At the same time, a message prompting a confirmation response is displayed on the CRT display 24 (Sr1). In this state, when the operator confirms the floppy disk 28a and responds with a confirmation response from the keyboard 23 or mouse 29 (ST9'), data output processing to the floppy disk 28a is executed (
STIO).

As a result of this process, the next file-based code data is mistakenly written to the floppy disk of the output light that was outputted at volume 1. It is possible to prevent the file structure from being changed.

On the other hand, if it is determined in step ST5 that the retrieved data is code data in units of volumes, the attribute information A of the data for which output processing was performed immediately before.
It is determined whether D is code data and the processing unit is a volume, that is, whether the attribute or processing unit has changed (STIO). As a result, if there is no change in the data attributes or processing units, a message will be displayed on the CRT display 24 requesting to replace the floppy disk, and a message will be displayed prompting for a confirmation response in order to continue output processing in units of volumes. (ST1
2). When the operator confirms with the keyboard 23 or mouse 29 (ST13), the floppy disk 28
Output processing to a is executed (S T 14).

Through this process, code data for the next volume unit is mistakenly written to the floppy disk of the output light that was outputted in volume units immediately before, and the data stored in the floppy disk of the output light is destroyed. It is possible to prevent this from happening.

Furthermore, if it is determined in the previous step STI 11 that a change has occurred in the data attributes or processing unit, a message will be displayed on the CRT display 24 to the effect that the processing unit has changed to a volume unit. Along with
A message prompting a confirmation response is displayed (ST15).

In this state, when the operator makes a confirmation response from the keyboard 23 or mouse 29 (ST16), output processing to the floppy disk is executed (ST17).

Through this process, code data for the next volume unit is erroneously written to the floppy disk of the output light that was outputted in file units just before, and the file data and file structure stored in the floppy disk of the output light are written. can be prevented from being altered or destroyed.

In the above embodiment, the processing unit is a file unit or a volume unit, but the same applies to data in which multiple code data files are merged and specified to be handled as one processing unit. It is possible to perform output processing in multiple units, and it is possible to avoid a situation where data in different processing units is accidentally destroyed.

In addition, the present invention is not limited to the above embodiments, and it goes without saying that various modifications can be made without departing from the gist of the invention.

[Effects of the Invention] As described in detail above, according to the present invention, when outputting different types of storage information stored in the storage means at once, the determination means adds the information to the storage information to be output. The type information of the stored information that has been outputted is determined, and based on the determination result of this determining means, it is determined by the comparing means whether or not the type information of the stored information output immediately before has changed, and it is determined that the type information has changed. If it is determined, by displaying the content of the change in the type information on the display means, even when information with different processing units and attributes is mixed and output in bulk and written to the storage means, it is possible to prevent the change in the type information from having already been written. Therefore, it is possible to provide an information retrieval device that can prevent the destruction of stored information.
