Description

The present invention relates to, for example, an electronic filing apparatus, and in particular, integrates and manages image data and code data using an optical disc. The present invention relates to an information retrieval apparatus capable of performing the following.

(Prior Art) In this type of information retrieval apparatus, for example, code data in units of files created by a personal computer and code data in units of volumes stored in a storage medium such as a floppy disk also have respective attributes. It is possible to collectively store and manage them on an optical disc in accordance with the processing unit. Here, the attribute refers to a data type such as image data or code data, and the processing unit refers to a data processing unit such as a file unit or a volume unit.

By the way, in this type of information search device, data having different attributes or processing units stored in an optical disk is searched, and data having different attributes or processing units are mixed and stored in an external storage medium such as a floppy disk. It is possible to output all at once. However, in this batch output processing, data is output to an external storage medium without discriminating the attributes and processing units of data to be output. For this reason, for example, even though the processing unit of the data to be output has changed from a file unit to a volume unit, the operator does not notice it and overwrites the necessary data previously written, and In some cases, embedded data was destroyed.

(Problems to be Solved by the Invention) According to the present invention, when data having different processing units and attributes are mixed and output collectively and stored in a storage medium, already written data may be destroyed. The purpose of the present invention is to solve the problem. Even when data having different processing units and attributes are mixed and stored in a storage medium by batch output, destruction of already written data is prevented. It is an object of the present invention to provide an information retrieval device capable of preventing the information retrieval.

[Configuration of the Invention] (Means for Solving the Problems) The present invention relates to a storage means for storing different types of storage information to which type information indicating the type of storage information is attached, and collectively storing the storage information from the storage means. When outputting the stored information, the discriminating means for discriminating the type information attached to the storage information to be output, the discrimination result of the discriminating means, and the type information of the stored information output immediately before the stored information are It comprises a comparing means for comparing whether or not they are the same, and a display means for displaying the contents of the change in the type information when the type information is determined to be different by the comparing means.

(Operation) According to the present invention, when the storage information of different types stored in the storage means is output collectively, the type information of the storage information attached to the storage information to be output is determined by the determination means. From the determination result of this determination means, it is determined by the comparison means whether or not the type information of the storage information output immediately before has changed, and when it is determined that the type information has changed, the content of the change in the type information is determined. By displaying the information on the display means, it is possible to prevent the already written information from being destroyed even when the information having different processing units and attributes is mixed and output to the storage means in a batch.

Next, how to manage image data and code data in a unified manner will be described from the viewpoint of document management.

That is, the document management system in this embodiment is the second
As shown in the figure, there are four levels of cabinets, binders, documents, and pages, and the cabinets are associated with one side of the optical disc 19. Up to eight binders can be defined in the cabinet, and up to 30,000 documents can be registered in the binder. Each document has a title, and its structure is defined for each binder.
The above documents are the basic unit of the file. In addition to the title,
Annotation (document description) can be added. Also,
The document consists of up to 4095 pages.

Such a management system considers consistency with a paper file, and a page corresponds to one paper file.
In this information processing apparatus, code data is also managed at the page level.

That is, the above-described page is composed of one sheet of image data, one floppy disk data (volume batch data),
File data or data obtained by merging the above three types of data.

As a result, for example, in one document, as a first page, a source file group (code data) of a predetermined program, as a second page, a program specification (code data) created by a word processor, as a third page, What has conventionally had to be managed completely separately, such as processing results (image data), can be managed very effectively.

As shown in FIG. 3, all the image data and code data stored on the optical disc are composed of a header HD and a data
It consists of DT. In the header part HD, attribute information AD for identifying image data or code data is stored, and when the data is code data, processing unit information UD for identifying whether the data is a file unit or a volume unit. Is stored. The same information is set for the merged data.

In the above configuration, referring to FIG.
A description will be given of an operation when a document in which code data in a file unit and code data in a volume unit are mixed is retrieved from the optical disk 19 and output collectively to a floppy disk 28a as an external storage medium. Is read from the optical disc 19 by a well-known search process,
This data is stored in the optical disk drive 22, interface circuit
The data is stored in the main memory 13 through the memory 17. The CPU 12 examines the header HD of the read data to determine the attribute information AD of the data (ST1). As a result, if the data retrieved from the optical disk 19 is image data, a message to the effect that output to the floppy disk 28a is inappropriate and a message indicating that output to the floppy disk 28a cannot be A message prompting a response is displayed (ST2). In this state, when the operator confirms with the keyboard 23 or the mouse 29 (ST3), the output processing of this image data to the floppy disk 28a is not executed. Then, it is determined whether or not the processing of all the documents specified as the output target has been completed (ST4), and if not completed, the processing of the next data is executed.

On the other hand, if it is determined in step ST1 that the searched data is code data,
HD processing unit information UD is determined (ST5). As a result,
If the data is file-based code data, it is determined whether the attribute of the data that has just been subjected to the output processing is code data and the processing unit is a file unit, that is, whether the attribute and the processing unit have changed. (ST6). When there is no change in the data attribute and the processing unit, the output process of the floppy disk 28a is executed as it is (ST
7). The content of the header HD of the output information is stored in, for example, the main memory 13, and the content is updated each time information is output.

If it is determined in step ST6 that the attribute of the data or the processing unit has changed, a message indicating that the attribute of the data has changed to code data or the message that the processing unit has changed in a file unit is issued. , CRT
A message prompting a confirmation response is displayed on the CRT display 24 while being displayed on the display 24 (ST8).
In this state, when the operator confirms the floppy disk 28a and the operator confirms and responds from the keyboard 23 or the mouse 29 (ST9), a process of outputting data to the floppy disk 28a is executed (ST10).

By this process, the code data of the next file unit is erroneously written to the output destination floppy disk that has been output-processed immediately by volume unit, and the file structure in the output destination floppy disk output by volume unit is incorrectly written. Changes can be prevented.

On the other hand, in the step ST5, when it is determined that the searched data is the code data of the volume unit, the attribute information AD of the data on which the output processing has been executed immediately before is determined.
Is the code data, and it is determined whether the processing unit is a volume, that is, whether the attribute or the processing unit has changed (ST10). As a result, if there is no change in the data attribute and the processing unit, it is necessary to replace the floppy disk in order to continue the output processing in the volume unit.
A message is displayed on T display 24, and a message prompting a confirmation response is displayed (ST12). When the operator confirms the response from the keyboard 23 or the mouse 29 (ST13), an output process to the floppy disk 28a is executed (ST14).

By this process, the code data of the next volume unit is erroneously written to the output destination floppy disk that has been output-processed by the volume unit immediately before, and the data stored in the output destination floppy disk is destroyed. Can be prevented.

When it is determined in step ST11 that the attribute of the data and the processing unit have changed, the CRT
A message indicating that the processing unit has been changed in volume units is displayed on the display 24, and a message prompting a confirmation response is displayed (ST15). In this state, when the operator acknowledges from the keyboard 23 or the mouse 29 (ST16), an output process to the floppy disk is executed (ST17).

With this process, the next volume unit of code data is erroneously written to the output destination floppy disk that has just been output in file units, and the file data and file structure stored in the output destination floppy disk are incorrectly written. Can be prevented from being changed or destroyed.

In the above-described embodiment, the case where the processing unit is the file unit and the volume unit has been described. However, the same applies to the data that is specified as a plurality of code data files that are merged and handled as one processing unit. Output processing can be performed at the same time, and it is possible to avoid a situation in which data in different processing units is erroneously destroyed.

In addition, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the invention.

[Effects of the Invention] As described above, according to the present invention, when the storage information of different types stored in the storage unit is output collectively, the storage information to be output by the determination unit is added to the storage information to be output. The type information of the stored information is determined, and from the determination result of the determining means, whether or not the type information of the stored information output immediately before has changed is determined by the comparing means, and it is determined that the type information has changed. In this case, the content of the change in the type information is displayed on the display means, so that the information having different processing units and attributes is mixed and output to the storage means at the same time. An information retrieval device capable of preventing destruction of information can be provided.
