Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a single drive
A system, that is, a floppy disk copy (backup) method suitable for use in various OA devices such as a personal computer having only one floppy disk drive or a word processor, and a floppy disk type time recorder using this copy method. Regarding

[0002]

2. Description of the Related Art In a single drive system personal computer, word processor, time recorder, etc., in order to back up the contents (data) stored in a floppy disk to another floppy disk, first, Insert the copy source floppy disk into the single drive system, write the contents to the work file on the system side, then pull out the copy source floppy disk and insert the copy destination floppy disk instead, and the contents of the work file It is designed to write to this copy destination floppy disk, but there is a large amount of copy of the above floppy disk and the file memory capacity of the system side is smaller than this copy amount, or it is used for copying. Memory capacity When click region is small, it is necessary to repeat the copy and insert a plurality of times alternately each floppy disk in the source and destination to the system.

However, since the replacement work of the floppy disks is all performed manually by the operator, the order of replacement of the floppy disks of the copy source and the copy destination is confused as the number of copies increases and the number of times the floppy disks are replaced increases. Various insertion mistakes such as inserting the same floppy disk twice in succession or misusing a completely different floppy disk, and
There is a problem in that there is a high probability of misuse and the like, resulting in various accidents such as omission of copy and destruction of copy content.

[0004]

Therefore, conventionally, the label of each copy source and copy destination floppy disk is provided with a symbol or number indicating the type or order of the source or destination, or a mark or the like, or at the time of copying. There were measures taken to prevent the mistake of replacing the floppy disks or the mistake of using them by outputting a message to the system display to prevent the order of floppy disks or a mistake in replacing them. However, it was not possible to prevent the mistaken replacement of the floppy disk or the mistaken usage of the floppy disk by using the passive preventive measures.

Therefore, the technical problem of the present invention is to prevent the mistaken replacement and the mistaken use by providing means for notifying the occurrence of the mistaken replacement or the mistaken use of the floppy disk in copying the contents of the floppy disk. Therefore, it is necessary to prevent accidents such as omission of copy and destruction of copy contents.

[0006]

[Means for Solving the Problems] Means taken in the present invention for solving the above technical problems are as follows. In a method of copying the contents of a floppy disk using a single drive system such as a personal computer or a word processor of a single drive system, (1) identification information is provided to each of the copy source and copy destination floppy disks. An identification information area to be recorded is provided, and if the identification information recorded on each of the copy source floppy disk and the copy destination floppy disk is the same at the first writing to the copy destination floppy disk, Rewrite the identification information to another content. (2) If the identification information recorded on each of the copy source and copy destination floppy disks is the same when reading from the copy source or writing to the copy destination, a warning to that effect is given as a replacement error. (3) When the identification information of the copy destination floppy disk is rewritten, the rewritten identification information should be restored to the original identification information when the copying is completed.

A time recorder of a single drive system configured so that the working data of each person calculated according to the input of the personal code can be stored in a floppy disk and the data can be copied to another floppy disk as needed. (4) An identification information area for recording identification information is provided on each of the copy source storing the above work data and each copy destination floppy disk to which this work data is copied, while the above time recorder has a copy destination. When the first writing to the floppy disk of, if the identification information recorded on each of the copy source and copy destination floppy disks is the same, the identification information of the copy destination floppy disk is rewritten to another content. Provide rewriting means. (5) When reading from the copy source or writing to the copy destination, if the identification information recorded on each of the copy source and copy destination floppy disks is the same, a warning means is provided as a replacement error warning. To be provided.

[0008]

The above means operates as follows. If the identification information recorded on the copy source floppy disk and the copy destination floppy disk is different, the element of (1) above can write the contents of the copy source floppy disk to the copy destination floppy disk as it is, and both If the identification information of the same is the same and the writing of the copy is the first, the identification information of the copy destination floppy disk is changed to other information to perform the copy, and the copy operation from the next time onward is the changed identification. Make sure you can follow the information.

The element (2) above is such that if the order of inserting the floppy disks into the system is incorrect, that is, if the order of source → destination → source → destination ... is incorrect, the identification information of the copy destination and the copy source will be the same. If a warning is issued when this same information is read, it is possible to inform the operator that the floppy disk insertion order is incorrect. This makes it possible to prevent accidents such as destruction of copy contents.

The element (3) described above rewrites the rewritten identification information to the original content when the copying is completed when the identification information of the copy destination floppy disk is rewritten at the first writing. Therefore, the identification information written on the floppy disk and the identification information written on the label can be matched to prevent confusion after copying.

The element of (4) above is, in a floppy disk type time recorder for storing the working data of each person in a floppy disk, copying the working data of each person stored in the floppy disk to another floppy disk for backup. In this case, when the memory capacity of the time recorder is small and the floppy disk is replaced several times to copy the contents of the memory, the identification information of the copy source and copy destination floppy disks is the same, and the copy writing If it is the first time, since the identification information of the copy destination is changed to another content, it is possible to surely proceed with the copy work from the next time onward according to the changed identification information.

The element of the above (5) is that when the insertion order of the floppy disks is wrong, the warning means provided in the time recorder gives a warning of the mistake, so that the operator can be notified of the mistake in replacing the floppy disk. By substituting the correct floppy disk according to this warning, it is possible to accurately copy the work data of each person to the copy destination floppy disk. As described above, the technical problems described above can be solved by the above means, and the problems of the conventional technology can be solved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of a floppy disk copying method according to the present invention and a floppy disk type time recorder using this copying method will be described below in detail with reference to the accompanying drawings. FIG. 1 is an external view of a floppy disk type time recorder according to an embodiment of the present invention, in which a time card (not shown) has a slot 1a on an upper surface of the time recorder indicated by reference numeral 1. It is opened, and the front panel displays the time data, a floppy disk replacement message, which will be described later, and a warning when the floppy disks are in the wrong order, and inputs or changes various data. An input key 3 used in the case is provided, and further, a single drive system 4 having an insertion opening 4a of a floppy disk 5 opened on the front surface of the recorder 1 is mounted inside the time card from the insertion opening 1a. When you insert the, the employee code recorded on the time card is read, and as a result, the employee's employment data is calculated and this The printing on the appropriate printing column of the time card, and, has a mechanism for storing on a floppy disk 5 inserted into the single drive system 4.

FIG. 2 is a block diagram showing the electrical construction of the above-mentioned floppy disk type time recorder according to the present invention, in which a bus 12 is interposed between a CPU 10 and a storage section 11 constituted by a ROM and a RAM. In addition to the display 2, the input key 3 and the single drive system 4 described above, the interface circuit 13 connected by the above-mentioned circuit 6 detects the reference time clock signal 6 and the inserted time card. A card sensor 7 for reading a personal code, a motor 8 for feeding a card for pulling in and feeding the inserted time card, and discharging it, and a printer 9 for printing working data on the time card are connected. The system is so controlled as to operate in accordance with the system program stored in the ROM of the storage unit 11.

In the single-drive floppy disk type time recorder configured as described above, when the work data of each person stored in the floppy disk 5 is copied to another floppy disk for backing up,
First, the copy source floppy disk 5 is inserted into the single drive system 4, the data of the floppy disk 5 is temporarily stored in the RAM of the storage unit 11, and then the copy source floppy disk 5 is pulled out. , A copy destination floppy disk (not shown) instead
Is inserted into the single drive system 4, and the above R
Although the data stored in the AM is written on the floppy disk of the copy destination to finish the copying, the storage capacity of RAM such as a time recorder or a simple personal computer or a word processor is the capacity of the floppy disk. If the work area of the RAM that can be used for copying is less than the capacity of the floppy disk, it is not possible to complete the above copying operation once, and the floppy disk of the copy source and the copy destination cannot be copied. It is necessary to alternately replace and copy the single drive system 4 a plurality of times.

However, while repeatedly replacing the copy source floppy disk and the copy destination floppy disk, the source → destination → source →
There is a case in which the order of ... is lost and the same floppy disk is inserted twice in succession, resulting in omission of copy or destruction of copy contents. However, in the present invention, each floppy disk of the above-mentioned copy source and copy destination is destroyed. The disc is provided with an identification information area (for example, in the case of MSDOS, an area for recording "OEM name and version" existing before BPB in the 0th sector of the disk is used), and the identification information of each disk is provided in this area. Is recorded and the identification information of the copy source and that of the copy destination are compared at the time of copying to eliminate the above-mentioned insertion error (exchange error) of the floppy disk.

Next, the processing procedure for copying the contents of the floppy disk according to the present invention will be described with reference to the flow charts shown in FIGS. In the first step S1, the copy source floppy disk 5 is inserted into the single drive system 4, and in the next step S2, the identification information recorded on the copy source floppy disk 5 is read and stored in the storage unit 11. The data is stored, and the process proceeds to the next step S3 to secure a work area in the storage unit 11, and the process proceeds to the next step S4.

In step S4, the data (working data) stored in the copy source floppy disk 5 is written in the work area, and when this writing is completed, the flow advances to step S5 to copy the floppy disk to the display device 2 as the copy destination. A message for replacing the floppy disk 5 of the copy source is removed from the single drive system 4 in step S6 according to this message, and the floppy disk of the copy destination is inserted instead.
Then, the identification information recorded on the copy destination floppy disk is read and stored, and the next step S
Go to 8.

In step S8, the identification information (copy source) stored in step S2 is compared with the identification information (copy destination) stored this time, and if it is determined that both identification information are the same, the next step S9. In step S10, the identification information of the copy destination floppy disk is changed to another content. Then, in step S10, the identification information of the copy destination floppy disk is rewritten with the changed identification information and the operation proceeds to step S11. However, if it is determined in step S8 that the identification information of the copy source and the identification information of the copy destination are different, the process directly proceeds to step S11.

In step S11, the above-mentioned data in the work area is written in the copy destination floppy disk, and then it is judged in step S12 whether or not the copying is completed. If all the copying is completed, step S13 is executed.
If the copy remains and the copying is continued, the process proceeds to step S16, a message to the effect that the floppy disk is replaced with the copy source is again displayed on the display unit 2, and the process proceeds to step S17 shown in FIG.

In step S13 shown in FIG. 3, it is determined whether or not the identification information of the copy destination floppy disk has been rewritten at the time of copying, that is, whether or not the above-described steps S9 and S10 have been performed, and rewriting is performed. If there is, the process proceeds to the next step S14, the rewritten identification information is restored to the original identification information and recorded in the copy destination floppy disk, and further the process proceeds to step S15 to release the work area and finish the processing. If it is determined in the above step S13 that there is no rewriting, the process directly proceeds to step S15 and the processing is ended.

On the other hand, in step S17 shown in FIG.
According to the message displayed in step S16, the copy destination floppy disk 5 is pulled out from the single drive system 4, and the copy source floppy disk 5 is used instead.
Is inserted again, and then the process proceeds to step S18 to determine whether the identification information of the copy source floppy disk 5 is correct, that is, whether it is the same as the identification information stored in step S2 (copy). Original floppy disk 5
Identity) is determined, and if it is correct, the next step S1
9 proceeds to write the continuation or remaining data of the copy source floppy disk 5 to the work area described above, and if not correct, proceeds to step S20 to display a warning message on the display 2 indicating that the floppy disk is wrong. ,
Prompt to replace the copy source floppy disk 5 with a correct one.

When the writing to the work area is completed in step S19, the process proceeds to the next step S21, and a message for exchanging the floppy disk for the copy destination floppy disk is displayed on the display unit 2, and in the next step S22, this message is followed. When the floppy disk of the copy destination is replaced with the floppy disk 5 of the copy source and is inserted into the single drive system 4, the process proceeds to step S23, the identification information of the inserted floppy disk of the copy destination is read, and the floppy disk of the copy destination is read. Is judged, and if it is correct, the process returns to step S11 and the data writing process is repeated. If the inserted copy destination floppy disk is wrong, the process proceeds to step S24 and a warning message is displayed. The floppy disk is displayed on the display unit 2. Encourage the exchange.

The above-described processes shown in FIG. 4 are repeated any number of times until the entire contents of the copy-source floppy disk 5 are written in the copy-destination floppy disk. Is executed to end the process.

[0025]

As described above, according to the floppy disk copy method of the present invention, the capacity of the memory on the system side is small, and in the single drive system, the copy source and copy destination floppy disks can be used. Even when repeatedly inserting data into a single drive system and copying the data, the floppy disks of the copy source and the copy destination can be replaced in order without fail, and thus, It is possible to prevent accidents such as copy omissions and data destruction due to mistakes in replacing floppy disks during copying (during backup), which is suitable for implementation in personal computers or word processors. Floppy disk type time recorder using the method Reliably individual's work data stored in the disk be one that can exhibit the advantage of a backup copy to another floppy disk,
The effect is extremely high.
