Abstract

PURPOSE:To facilitate operating of an operator and to improve the efficiency of registration without entering a file name every time the file is inputted by writing file data and control information of the file data independently on an external memory. CONSTITUTION:The whole system is controlled by a CPU 62 connected to a bus 61 of the system according to a program stored beforehand in an ROM 63. Data, etc. are inputted from a keyboard 5 connected to the bus 61, and input data from an image inputting device 3 are applied to the bus 61 through an input interface 65, and written on a large capacity disk 7 through an RAM 64 and a disk interface 66 under control of the CPU 62. File data and control information of the file data are written on the disk 7 independently. Thus, operation of an operator is made easy and the efficiency of registration is improved without entering a file name every time the file is inputted.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a file creation method, particularly to a file creation method when filing data such as images and codes in an external storage device.

[Prior art]

BACKGROUND ART Floppy disks, hard disks, and the like have been commonly known as external storage devices.

When data files are written to these disks, they are always written along with file management information called a directory.

Generally, when an operator creates a file, he or she registers the file name using the keyboard and then inputs data to create the file. Once you have finished entering the data, enter the command to end the file and the file will be created on disk along with the directory. This conventional file creation method will be explained using FIGS. 1 and 2.

FIG. 1(a) is an internal configuration diagram of a directory, where 11 is an area for storing the file name of data, 12 is the first trunk for data writing, an area for storing sector addresses, 13 is the last trunk for data write, This is an area that stores sector addresses. Figure 1 (a) is a diagram of the structure of data files and directories when creating files on the disk, and Figure 2 is how files are created on the disk.
1 is a flowchart showing step 1. The file creation procedure will be explained according to this flowchart.

At Sl, the 2-isle name inputted from the keyboard is written into the file name 11 area in the directory area 1 of the disk. Then, in S2, the address of the first track and sector for data file writing is registered in area 12 in directory l, and the data file input standby state is entered.

In S3, the input data is developed on the main memory. At s4, it is determined whether the data input is completed, and if the input is completed, the data is written on the disk (S5) and data file 1 is created. When the writing is completed, the writing end track is displayed in S6.
The address of the sector is registered in the file end track of directory 1, sector registration area 13. In this way, the file name, the first track and sector, and the last track and sector of the file are written in the directory, and the file writing is completed and a file is created on the disk as shown in Figure M1 (b). Ru.

As in the past, if the data file was only a character data file input from the keyboard, it was not so troublesome to register the file name before inputting the file.

However, due to advances in electronics and advanced technology in recent years.

With the advent of large-capacity, high-density external storage devices such as optical disks, opportunities to handle not only code information t9 but also image information have increased. When writing image information as a data file to an external storage device, a computer system equipped with an image input device as shown in FIG. 3 is generally used. When such a system is used to create a file using the method described above, the operator must type in the file name from the keyboard each time an image is input from the image input device, which is very cumbersome. In particular, it has been difficult to continuously process image information using an automatic document feeder or the like.

〔the purpose〕

The present invention has been made in view of these points, and provides a file creation method that allows data files and file names to be written separately.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 5 is an internal configuration diagram of a directory expanded on the main memory to which the present invention is applied, in which storage areas 81, 84 and 87 are storage areas for file names, and 82, 85 are storage areas for file names.

88 is a storage area for the address of the first track and sector;
83, 86, and 89 are storage areas for the addresses of the final track and sector. Figure 6 (a) is a diagram of the internal configuration of a disk when only a data file is written on the disk, and Figure 6 (b) is a diagram of the disk when a file is created with a data file and directory written on the disk. It is an internal configuration diagram.

FIG. 7 is a flowchart showing the procedure for creating a file on the disk. (a) is a data file registration procedure, and (b) is a directory registration procedure.

Hereinafter, the file creator 1 of the present invention will be explained according to the flowchart of FIG.

When the operator gives a data file registration command from the keyboard 4, a file name area 81 is secured in the directory area 8 on the main memory (T1), and the address of the first track and sector to be written in the data file is registered in 82 of the directory area 8. (T2). At T3, an image input OK command is sent to the image input device 3. The image input device 3 starts reading the original, and the control unit 6
When the information is sent, the information is transferred to the large-capacity disk 7 and written as a data file on the disk as shown in FIG. 5 (T4). When the writing of the data file to the main memory is completed, the writing of 7g is completed.The input and writing of one data file is completed using the above procedure. At T7, it is determined whether the data file registration has been completed, and if not, the steps from T1 to T6 are repeated again to write another data file to the disk. Now, if we input three files, the second file will be written in the directory area 84 to 86 on the main memory, the third file will be written in the directory area 87 to 89, and the data files will be written in the directory area 10 and 11 on the disk. written. When the operator issues a data file input end command, it is determined at T7 that the data file registration is complete, and the file is written on the disk 7 in the state shown in FIG. 5(a).

Next, the operator receives a command to register a file name and inputs the file name of the data file 9 manually entered (-) from the keyboard 4, and the entry file 2-me is registered in the file name area 81 above 1'5. do(
T8). Then, at T9, directory information 81 to 83 is written to the directory area 14 of the disk. 1
When the second file name is written, the next file name is requested, and when the file name is input, the above T8
~ Repeat the procedure of T9, and enter the file name of data file 10 or file name field @84. Directories 84 to 86 are directory area 1 on the disk.
3, the file name of the data file 11 is registered in the file name area 87, and the file name of the data file 11 is registered in the file name area 87.
89 are hidden in the directory area 12 on the disk. When all file names have been registered, a command to end file name registration is given. At that point, Figure 5'
Files and directories like (1+) are created on the disk.

In the tree example, compound,! I gave an example of registering the file name after writing the take information as a file to the disk, but conversely, after registering the file name,
An example in which data information is written to the disk as a file may also be used. In this case, when registering the file name, confirm the address registration area of the first trunk and sector for data file writing and the address registration area of the last trunk and sector. When a data file corresponding to that file name is written to the disk, the first trunk and sector and the last trunk and sector are written to the reserved area.Then, at the end of data file writing, Writes the expanded directory on main memory to disk.

A flowchart in this case is shown in FIG. Figure (a)
is the first register of the directory, and (b) is the first register of the data file.

At T21, like T8, a file name is written in the file name area on the main memory. At T22, the address of the data file first write trunk and sector is written on the main memory.
a j7. Secure the address registration area for the winter trunk and sector.

At T23, similarly to TIO, it is determined whether all file names have been registered.

At T24, the first track and sector are written in the secured first track and sector registration area on the main memory. T25
-T28 are similar to T3-T6. At T29, information in the directory area on the main memory is written to the directory area on the disk. At T2O, as with T7, it is determined whether or not all data file registration is completed.

Also, in the embodiment, image information was given as an example of file data, but of course coat information is also acceptable, and the number of data files is three in the embodiment.
Any number is fine as long as it can be managed by the computer. Further, writing of the file name and data may be performed in an interactive manner with the image processing system.

〔effect〕

As explained above, if the present invention is used, there is no need to input a file name every time a data file is input, which makes the operation easier and improves registration efficiency.
