[0002]

2. Description of the Related Art A large number of form data are created by a host computer, and if necessary, recorded on a magnetic tape. The form data is read into a PC having a data format different from that of the host computer, and only necessary items are read. 2. Description of the Related Art There is known an electronic form system for extracting a required form, extracting necessary forms, totalizing the forms, and combining and searching a plurality of items.

FIG. 5 is a diagram showing an example of a conventional electronic form system. In this figure, reference numeral 10 denotes CRMT (Cart
ridge Magnetic Tape, magnetic tape housed in a cartridge). Reference numeral 11 denotes a CRMT driving device.
Data is recorded in the RMT 10 or data is read from the CRMT 10. The CRMT 10 records form data as the user data in accordance with a predetermined format. FIG. 6 shows an output example of the form data recorded in the CRMT 10. The form data shown in FIG. 6 is formed by combining and outputting a predetermined form and data in each entry field.

In FIG. 5, reference numeral 12 denotes a host computer.
Here, the form data 14 is created. The form data 14 is C
It can be formed by data read from the RMT 10 by the CRMT device 11. Of course, it may be created by means different from CRMT10. Form data 1 read here
4 is the same as the form data shown in FIG.
The host computer 12 also stores data format information 16. The data format information 16 includes index key data, information files, form parameters and editing parameters, user external characters, and the like. Here, the information file includes data format information, a data structure system, a password, and the like.

In the host computer 12, the created form or the form read from the CRMT 10 is displayed on display means (not shown) as necessary. The required form can be output to the COM system 18. Here the COM system 18 is Comp
uter Output Microfilm System, meaning that computer output is directly converted into microfilm and output. By converting the form into a microfilm, it is possible to ensure the storability and authenticity (prevention of correction and deletion) of the data.

[0006] Reference numeral 20 denotes a personal computer (hereinafter referred to as PC).
This PC 20 is the host computer 1
2 has a different data format. For example, in the host computer 12, UNIX (UNIX System Laboratories, In
c. developed and licensed), X ・ WINDOW
While supporting multi-job and multi-window by System (trademark of MIT, USA), PC 20 is compatible with Windows NT / 95 (Windows system name of Microsoft Corporation). Therefore, the data formats of the host computer 12 and the PC 20 are different.

[0007] The PC 20 reads the form data 14 and the data format information 16 from the host computer 12 or the CRMT driving device 11. At this time, the form data 14 is compressed to form compressed form data 22. Note that the data format information 16 is read as it is into the PC 20 and becomes the data format information 24. Reference numeral 26 denotes a printer which prints out form data edited and processed by the PC 20.

Reference numeral 28 denotes a CD-R (Co) as an external recording medium.
mpact Disc Recordable, an uncorrectable and writable compact disc). This CD-R28 is C
The data is loaded into the DR control unit 30 and data writing and reading are performed. The PC 20 writes and records the compressed form data 22 in which the data is compressed on the CD-R 28. At this time, data format information 16 such as index key data, form parameters and edit parameters, user external characters, etc.
Is also written on CD-R28.

[0009]

In the above-described conventional system, the PC 20 can edit the form data using the CD-R 28. That is, the compressed form data 22 is read from the CD-R 28 to restore the form data, and can be edited and printed out as needed.

However, the data read from the CD-R 28 is used for forming data used in the PC 20 and cannot be used in the host computer 12 having a different data format. Therefore COM
It could not be output as film. For this reason, the form data 14 used by the host computer 12 must always be read from the CRMT 10, and the CRMT 10 and the COM film must all be stored in accordance with the request of the “electronic book storage method” described later.

However, the CRMT 10 is housed in a cartridge and is larger than the CD-R 28, and its data storage capacity is significantly smaller than the CD-R 28. For example, the storage capacity of the CRMT 10 is 12,000.
Compared to 0 pages / book, the number of CD-R28 is about 300,000 pages / sheet. For this reason, there is a problem that the accommodation space of the CRMT 10 becomes large, and handling thereof becomes troublesome.

On the other hand, in recent years, it has been widely practiced to convert accounting books into electronic data and store it in a form which can be processed by a computer. That is, all book documents are recorded on a CD-R or a hard disk, and are searched and edited so that they can be printed out in a timely manner. Such forms are required to be kept for a certain period by tax law, commercial law, etc.
The “Electronic Bookkeeping Law” regulates the storage.

According to the law, it is necessary to "store electronic data together for three years or to be able to search for recorded items on COM films" (Article 4.1-5 of the Enforcement Regulations of the law).
Also, the electronic form is specified as "can be converted to a COM film after a certain period of time and stored" (Article 4-3 of the Enforcement Regulations of the same law).

The COM system used here reads the print image information, which is the user data of the forms as it is, from a magnetic tape, converts it into a microfilm, and outputs it. Since the electronic data must be stored in a searchable form for a certain period of time, it has conventionally been necessary to store the magnetic tape (print image tape, PIT). For this reason, the storage space for the magnetic tape becomes large, and its handling is troublesome. The magnetic tape used here corresponds to the CRMT 10 in FIG.
