Abstract

PURPOSE:To decrease time required for error processing by discriminating an error caused at read/write and reading and displaying error information being the discriminated error content from a read means. CONSTITUTION:A CPU 8 sets a floppy disk control parameter to a prescribed area of a RAM 10 to designate a track number and a sector number to execute the write of a floppy disk via a floppy disk controller and a floppy disk driver 12. Succeedingly, a floppy disk drive status signal fed from the driver 12 to the controller 11 is read and the CPU 8 discriminates whether the write is executed normally or an error takes place, and write protect error or other error. Based on the result of discrimination, a corresponding error content is read from a ROM 9, displayed on a display section 3 and an alarm by a buzzer 7 is raised. This is similar to an error at read, the error content is displayed clearly and the time required for error processing is decreased.

Description

[Detailed Description of the Invention] [Industrial Application Field 1] The present invention relates to a floppy disk VL storage, and in particular, it is possible to prevent a J3 L error from occurring when writing data to a floppy disk or reading data from a floppy disk. The present invention relates to a floppy disk device that displays error information indicating the content of the error while passing through the FD and FA.

[Prior Art] As is well known, a floppy disk device is a storage device that uses a floppy C disk as a storage medium, and is used in a wide range of fields as a simple auxiliary storage device or a data input/output device.

FIG. 8 is a diagram showing the configuration of a conventional transaction processing system using a 1m floppy disk.

In FIG. 8, this transaction processing system is composed of one floppy disk device 1 and a plurality of ECRs (7!f cash registers) 2, each ECR 2
The sales data is transmitted to the floppy disk device 1 and written on the floppy disk.

By the way, in the process of self-transfer to a floppy disk,
When the floppy disk runs out of space to write data, the floppy disk is replaced, but at this time, a floppy disk with a different file name or a write-protected floppy disk is inserted. In such cases, an error message is displayed on the ECR2 display.

[Problems to be Solved by the Invention] In the transaction processing system shown in FIG. 8, the floppy disk group ra1 is normally installed at a location separate from the ECR2. Therefore, when replacing the floppy disk, the operator must replace the floppy disk If! After going to point 1 and replacing the floppy disk, return to ECR2 and perform the operation. If an error message is displayed at this time, go to point 1 again to process the error, such as replacing the floppy disk. I have to go to Tsubii Disk 'gA Station 1. Therefore, in the past, there was a problem that error processing took time.

Therefore, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a floppy disk device that makes it possible to shorten the time required for error processing.

Means for Solving Problem E] The floppy disk device of the present invention detects error contents and error information indicating the error contents that occur regarding the process of writing data to a floppy disk or the process of reading data from a floppy disk. A separately stored storage means, a display means for displaying any of the error information stored in the storage means, and a storage means for displaying any error information stored in the storage means, Error determining means for determining which error has occurred among the error contents of the means, and display #AIII for reading error information from the storage means and displaying it on the display means without indicating the error contents determined by the error determining means.
and means.

[Operation] In the present invention, in response to the occurrence of an error related to data writing processing or data reading processing, it is determined which error has occurred, and error information indicating the content of the determined error is displayed on the display means. That's what I do.

[Embodiment] FIG. 1 shows a floppy disk lf according to an embodiment of the present invention.
FIG. 1 is an external front view of the vehicle. In FIG. 1, a floppy disk insertion section 20, an indicator 3, a ready indicator lamp 4, a close switch 5, and a m[switch 6] are provided on the front panel surface of a floppy disk device 1. The floppy disk insertion section 20 is for inserting a floppy disk. The display 3 indicates data writing to the floppy disk 51! ! This is used to display error codes for errors that occur in processing or reading data from floppy disks. The ready indicator lamp 4 is a lamp that lights up when the floppy disk can be accessed. The close switch 5 is operated to interrupt access to the floppy disk and replace the floppy disk. T! 1 source switch 6 is fi! of floppy disk family N1. G! This is to switch on/off.

FIG. 2 is a side view of the floppy disk device 1 shown in FIG. 1. In FIG. 2, a floppy disk device 1
A buzzer 7 is installed inside. The buzzer 7 issues an alarm when an error occurs in the process of transmitting data to the floppy disk or in the process of reading data from the floppy disk.

FIG. 3 is a schematic block diagram showing the electrical configuration of a floppy disk device according to an embodiment of the present invention. In Figure 3, the floppy disk lV! 11 is provided with CF"tJ8. CPU8 is provided with ROM 9, RAMl0 and F
A CC (floppy disk controller) 11 is connected via an address bus 13 and a data passco 4.

F' (0M9 stores the CPU operating program based on the flowcharts shown in Figs. 6 and 7, which will be explained later), and also stores the error contents and the corresponding error as shown in Fig. 5, which will be explained in The RAM 10 includes a storage area as shown in FIG. 4, which will be explained later.The FDCl 1 controls an FDD (floppy disk drive) 12.

An FDD control signal is sent from FDCl 1 to FDCl 2, and an FDD status signal is sent from FDCl 2 to FDCl 1.

Here, the FDD III all signal includes, for example, a signal for controlling which track and which sector of the floppy disk is to be inserted. FDD status signal is F
This is a signal representing the state of DC12.

Further, the above-mentioned display 3 and buzzer 7 are connected to the CPtJ8.

FIG. 4 is an illustrative diagram showing the storage area of the tRAM 10 shown in FIG. In FIG. 4, the area 101 stores the media file name of the floppy disk exchange 11A hfh, and the area 102 stores the media file name after the exchange. Here, the media file name is a file name determined for each floppy disk, and for files containing many data items, the same file name is given to and registered on a plurality of floppy disks.

Furthermore, FDC parameters 1 to 3 are set in area 103. FDC parameters 1 to 3 are information that instructs which sector and which track on the floppy disk the data is to be inserted into. Furthermore, the area 104 stores FDC data.

FDC status is FDCI 1 normally t'l:II
This is information indicating whether or not it was received.

FIG. 5 is a diagram showing display data displayed on the display 3 shown in FIG. 1 and error details corresponding thereto. display! S
The display data displayed at 3 consists of, for example, three digits, the upper one being the status and the lower two digits being the data.

For example, the status is “'9°” as shown in 1J in FIG.
If it is, it indicates that there was an erroneous operation. For example, if the display data is ``901'', it means that the media was removed without file close processing, and if the display data is ``902'', for example, another medium with a different file name is set without closing the file. For example, if the status is "A", it indicates that a media check error has occurred. For example, if the display data is "AOI", it indicates that the media type is incompatible; for example, if the display data is "A O2°",
Indicates that a media with an error in the format was used. For example, △03" indicates that there was an error when checking the media file name. For example, "804"° indicates that the media in RAM 10 was used. Indicates that the size of the data stored in the buffer is larger than the file size allocated to the media.

Roughly speaking, if the status is, for example, "F", it indicates that a request is made to replace the medium due to a read/write error. If the display data is for example “FO1” or °“
F11” indicates that there was an error in the write result; for example, °“FO2” or “F12” indicates that there was an error in the CRC (cyclic redundancy check). , for example “”FO3”
Alternatively, "F13" indicates that there was a seek error, and, for example, "FO4" indicates that there was a write protect error, that is, an attempt was made to write to a file that is prohibited from entering.

6, 13, and 7 are flowcharts for explaining the operation of an embodiment of the present invention. In particular, FIG. 6 shows the operation when exchanging media, and FIG. 7 shows the operation when writing to an FDD. shows the operation. In addition, in this embodiment, the floppy disk Vt
[1 is connected to the ECR2 group as shown in FIG. 8, and is placed iiQ apart from the ECR211F'.

Next, the operation during media exchange will be described with reference to FIGS. 1 to 6.

Here, a case will be explained in which the operator replaces the medium without performing a close operation and then inserts another medium.

A new floppy disk is installed in CPU1 and the FD
The system waits until the FDD 12 is in the F$ ready state, and when the FDD 12 is in the ready state, the file name is read from the attached medium and stored in an area 102 in the RAM 10. Next, area 102
It is determined whether the media file name stored in area 101 is the same as the media file name before exchange stored in area 101, and if the file name is different, the buzzer 7 is turned on and the , the display 3 shows, for example, a path 902''.
is displayed and the operation ends. In this way, for example, if a floppy disk runs out of space to write data and the media is replaced; if a 0x2 disk with a different media file name is inserted, an error message will be displayed to that effect. Therefore, the operator can know what error has occurred without having to return to ECR2. Therefore, error processing can be performed quickly.

Next, the operation during FDDI processing will be described with reference to FIGS. 1 to 7.

CPU'8 writes FDC to CPU v7103 in RAM10.
Set parameters to specify track number and sector number. Then write to the floppy disk,
Subsequently, the FDC status is read and stored in area 104. Then, it is determined whether the writing is normal or not, and if the writing is normal, the operation is terminated, but if there is an error in writing, it is then determined whether there was a write protect error or not. Discern. If there is a write protect error, the buzzer 7 is turned on to emit a warning sound, and the display 3 displays an error message such as "F04". Further, if it is not a write protection error, the following error check is performed, the corresponding error is displayed on the display 3, and the buzzer 7 emits an alarm sound.

In addition, in the above-mentioned Real 11M@, when an error occurs, the buzzer 7 is simply turned on to generate an alarm sound, but the content of the error may be made clear by changing the tone of the buzzer, for example. . Further, the display 3 of the floppy disk device 1 may display errors that occur in processes other than writing to a floppy disk or reading from a floppy disk, such as transmission processing. Furthermore, the operating status of the floppy disk may be displayed on the display 3 of the floppy disk device @1.

[Effect of Application] As described above, according to the present invention, in response to an error occurring in the process of writing data to the floppy disk or the process of reading data from the floppy disk,
Among the error contents in the storage means, it is determined which error has occurred, and the error information indicating the corresponding error contents is read out from the storage means and displayed on the display means, so that the operator can read the floppy disk'&ffl. Since the details of the error can be known by looking at the display, error handling can be carried out quickly.
