Performs various data read / write to 9 ₁ and 9 _2.
As the FDDs 7 and 8, ones whose rotational speed can be switched by a control signal, that is, ones that can drive both the A-format FD and the B-format FD described above are used. As this type of FDD, for example, there is a DFR783F series manufactured by Alps Electric Co., Ltd.

In addition, in FIG. 2, reference numeral 11 denotes a ROM, which comprises a control program area for controlling weighing processing, printing processing, display processing, data writing processing, and the like, and a table for storing character patterns. . Reference numeral 12 denotes a RAM, which is a working area in which various flags and registers are secured, a preset data file for storing preset data, a total data file for storing total data, and a storage for storing reservation data. It is composed of a reservation data file and a work result data file for storing work result data.

Reference numeral 13 denotes a printer, and when the operator presses one print key of the function key 6b, the CPU 1 receives the information on the entry or exit from the RAM 12 read from the RAM 12 through the printer interface 14, and It is printed on the receipt slip or outgoing slip.

Further, reference numeral 15 denotes a rotary rack comprising a plurality of shelves on which a tray for storing a plurality of parts is placed. The operator inputs shelf number data indicating a storage position of the parts. The shelf number data is received via the rotating rack interface 16, and based on the shelf number data, the shelf on which the tray storing the corresponding parts is placed is rotated to a position where it can be easily taken out, and the position where the tray is taken out by the indicator light. Notify. For details of the configuration of the inventory management device including the electronic weighing device and the rotary rack 15, see Japanese Patent Application No. 1-225 previously proposed by the present applicant.

Perform the outgoing work. Read one reserved data. The shelf of the rotating rack 15 is rotated based on the read reservation data, and the take-out position is displayed by the indicator lamp. The operator pulls out the tray from the place where the indicator light is turned on. The operator takes out the component from the tray, weighs the component using an electronic weighing device, and counts the number of components. The delivery slip is printed by the printer 13 and issued. The operator replaces the tray. Read the next reservation data. The above-described processing is repeated to carry out the delivery of all the reserved parts.

Next, the read / write processing of various data by the CPU 1 to and from the FDs of different formats, which is a feature of the present invention, will be described with reference to the flowcharts of FIGS. First, a normal read / write processing routine of various data to the FD shown in FIG. 3 will be described. This process routine is executed for each accessing the CPU1 is FDD7 or FD9 ₁ is inserted into 8 or 9 _2.

[0019] CPU1, first, the process proceeds to step SA1, whether FDD7 or 8 is inserted into FD9 ₁ or 9 ₂ has been replaced, or, FDD7 or 8
FD9 ₁ or 9 ₂ determines whether the newly inserted. This determination is based on the F inserted in the FDD 7 or 8.
When D9 ₁ or 9 ₂ is replaced, or when FDD7 or 8 to FD9 ₁ or 9 ₂ is newly inserted,
The FD eject switch (not shown) is turned on / off,
Since a flag corresponding to the flag is set or reset, it is determined whether the flag is set.
If the result of this determination is “YES”, the following FD format selection process of steps SA2 to SA6 is executed. That is, the CPU 1 proceeds to step SA2. On the other hand, if the result of the determination in step SA1 is "NO", the flow proceeds to step SA8 described later.

In step SA2, the F-format is selected in the currently selected FD format (the default is A-format).
D9 ₁ or 9 ₂ are stored in the data, for example, F
After reading the ID of the AT, the process proceeds to step SA3. In step SA3, it is determined whether or not data could be read in the processing in step SA2. If the currently selected format is different, the ID
Since data cannot be read, a read error occurs, the result of determination in step SA3 becomes "NO", and the
U1 proceeds to step SA4. On the other hand, if the currently selected format is correct, step SA
Since the data can be read in the processing of step 2, the result of the determination in step SA3 is "YES" and C
PU1 proceeds to step SA8 described below.

At step SA4, the format of the FD is switched to another format, and a control signal is transferred to the FDD 7 or 8 via the FDD interface 10 to change the rotation speed according to each format. That is, when the A format is currently selected, the mode is switched to the B format, and when the B format is currently selected, the mode is switched to the A format. Then, the CPU 1 proceeds to step SA5.
At step SA5, the data stored in FD9 ₁ or 9 ₂ in the format of a switched FD, for example, after reading the ID of the FAT, the process proceeds to step SA6.

At step SA6, it is determined whether or not data could be read in the processing at step SA5. If the result of this determination is "NO", that is, in the case of a read error, the format is other than the format A and format B, or the format is unformatted, so the CPU 1 proceeds to step SA7. On the other hand, if the currently selected format is correct, the data can be read in the processing of step SA5.
The result of the determination in 6 is “YES”, and the CPU 1 proceeds to step SA8 described later.

At Step SA7, error processing is performed.
For example, after displaying on the display unit 5 that the FD data is not read, a series of processing is terminated. At step SA8, after a read / write processing of various data formats that are currently selected to FD9 ₁ or 9 _2, the series of processing is terminated. In the electronic weighing apparatus of this embodiment, each time data of one cluster is written to the FD 9, the file size up to that time is written to the directory entry. The memory of the electronic weighing apparatus, for example, the RAM 12 also stores the position of the data written to the FD up to that point. Therefore,
Even if data is read while data is being written to the FD 9, the data written so far is valid. This will be described later in detail.

Next, the FD 9 ₁ inserted into the FDD ₇

Proceed to.

In step SB2, it is determined whether or not data could be read in the process in step SB1. If the currently selected format is different, the ID data cannot be read, so a read error occurs and the result of the determination in step SB2 is “N”.
O ", and the CPU 1 proceeds to step SB3. On the other hand, if the currently selected format is correct, data can be read in the process of step SB1, and the result of determination in step SB2 is “YE
S ", and the CPU 1 proceeds to step SB7 described later.

[0026] At step SB3, switches the FD9 ₁ format which is inserted into FDD7 to other formats, it switched depending on the format of the rotational speed to transfer the control signal to FDD7 through the FDD interface 10. That is, when the A format is currently selected, the mode is switched to the B format. When the B format is currently selected, the A format is selected.
Switch to format. Then, the CPU 1 proceeds to step SB4. In step SB4, the data stored in FD9 ₁ with switched formats, for example, after reading the ID of the FAT, the step SB5
Proceed to.

In step SB5, it is determined whether or not data could be read in the process in step SB4. If the result of this determination is “NO”, that is, in the case of a read error, the format is other than the formats A and B, or the format is unformatted, so the CPU 1 proceeds to step SB6. On the other hand, if the currently selected format is correct, the data can be read in the process of step SB4,
The determination result of 5 is “YES”, and the CPU 1 proceeds to step SB7 described later.

At step SB6, error processing is performed.
For example, after an indication that not read data of the display unit 5 to FD9 _1, the series of processing is terminated. Step SB7
In the FDD7, the format currently selected in FDD7
After formatting the FD9 ₂ that is inserted into DD8, the process proceeds to step SB8. In step SB8, the FD
After copying the FD9 ₁ of data inserted in D7 is inserted and into FD9 ₂ to FDD8, the series of processing is terminated.

The FD 9 ₂ inserted in the FDD ₈
Unformatted FD inserted into FDD7 from

Corresponds to 7).

Next, the FD 9 ₁ inserted into the FDD ₇
A copy processing routine for copying data from the FD 92 to the formatted FD 92 inserted in the FDD ₈ will be described with reference to the flowcharts of FIGS. First, the CPU 1 proceeds to the process of step SC1.
The format of FD that has been selected for the current FDD7 data (default is A format) stored in FD9 _1, for example, after reading the ID of the FAT, the process proceeds to step SC2.

In step SC2, it is determined whether or not data could be read in the processing in step SC1. If the currently selected format is different, the ID data cannot be read, so a read error occurs and the result of the determination in step SC2 is “N
O ", and the CPU 1 proceeds to step SC3. On the other hand, if the currently selected format is correct, the data can be read in the process of step SC1, and the result of the determination in step SC2 is “YE”.
S ", and the CPU 1 proceeds to step SC6 described later.

[0032] At step SC3, switches the FD9 ₁ format which is inserted into FDD7 to other formats, it switched according to the rotational speed to each format and transfer the control signal to FDD7 through the FDD interface 10. That is, when the A format is currently selected, the mode is switched to the B format. When the B format is currently selected,
Switch to A format. Then, the CPU 1 proceeds to step SC4. In step SC4, stored in FD9 ₁ with switched format data,
For example, after reading the FAT ID, step SC
Go to 5.

In step SC5, it is determined whether or not data could be read in the processing in step SC4. If the result of this determination is "NO", that is, in the case of a read error, the format is other than the format A and format B, or the format is unformatted. Proceed to SC11. On the other hand, if the currently selected format is correct, step S
Since data can be read in the process of C4, the result of the determination in step SC5 is "YES",
PU1 proceeds to step SC6. In step SC6, the format of FD that has been selected for the current FDD8 data (default is A format) stored in the ₂ FD9 in, for example, after reading the ID of the FAT, the process proceeds to step SC7 in FIG.

In step SC7 of FIG.
It is determined whether or not the data could be read in the processing of step 6. If the currently selected format is different, the ID data cannot be read, so a read error occurs, the result of the determination in step SC7 becomes “NO”, and the CPU 1 proceeds to step SC8.
On the other hand, if the currently selected format is correct, the data can be read in the processing of step SC6, so that the determination result in step SC7 is “YES”, and the CPU 1 determines in step SC
Proceed to 12.

[0035] At step SC8, switches the FD9 ₂ format that is inserted into FDD8 to other formats, it switched according to the rotational speed to each format and transfer the control signal to FDD8 through the FDD interface 10. That is, when the A format is currently selected, the mode is switched to the B format. When the B format is currently selected,
Switch to A format. Then, the CPU 1 proceeds to step SC9. In step SC9, stored in FD9 ₂ in switched format data,
For example, after reading the FAT ID, step SC
Proceed to 10.

In step SC10, it is determined whether or not data could be read in the processing in step SC9. If the result of this determination is "NO",
In the case of a read error, since the format is other than the format A and format B or the format is unformatted, the CPU 1 proceeds to step SC11. On the other hand, if the currently selected format is correct, the data can be read in the processing of step SC9,
The result of the determination at C10 is "YES", and the CPU 1 proceeds to step SC12 described later. At step SC11, error processing is performed. For example, the display unit 5 displays the FD 9 ₁
Or 9 ₂ data can not be read, or, after FD9 ₁ or 9 ₂ has an indication is unformatted, the series of processing is terminated.

[0037] At step SC12, after copying in file units the FD9 ₁ of data inserted in FDD7 into FD9 ₂ that is inserted into FDD8, the series of processing is terminated. It should be noted that the FD 92 inserted in the FDD ₈ through the formatted F inserted in the FDD 7
D9 the copy processing of copying data to _1, is the same as that described above, description thereof is omitted.

In the embodiment described above, steps SA2, SA5, SB4, SC1, SC6 and SC
In each process of No. 9, when the FD data is read,
Although an example has been described in which the read error processing is immediately executed when a read error occurs, in this case, it may be a mere normal data read error. Do
It is also conceivable to perform a read error process when all read errors occur.

In the above-described embodiment, two different FD formats, ie, the A format and the B format, are automatically determined, and data is read from / read to the FD.
Although an example of writing has been described, the present invention is not limited to this, and it is of course possible to automatically determine three or more different FD formats and read / write data to / from the FD.

Further, in the above-described embodiment, the unformatted F
D9 ₂ describes a copy process of copying data from the formatted FD9 from ₁ in the same format as FD9 _1, FD by the flowchart shown in FIGS. 5 and 6
9 ₁ has been described copy processing for copying data to ₂ FD9 that are formatted from, in the processing of step SC10 in the flowchart of FIG. 6, of the case the determination result is "NO", FD9 ₂ is unformatted in some cases, it is conceivable to copy data from FD9 ₂ the FD9 ₁ FD9 after formatted in the same format as _1.

[0041] That is, when copying data from FD9 ₁ to FD9 _2, if FD9 ₂ is formatted,
Its format is prioritized, unless FD9 ₂ is formatted, after formatting in the same format as FD9 _1, it is also conceivable configured to copy data from FD9 ₁ to FD9 _2. In addition, in the above-described embodiment, since the device itself automatically determines the format of the FD and reads / writes data,
The operator does not know the format of the FD. Therefore, displaying the current FD format on the display unit 5 (including displaying only when the operator performs a certain key operation) may be considered.

By the way, the A format described above is frequently used in Japan, and the B format is widely used in the United States. For this reason, by automatically detecting the format of the FD, the operation mode of the electronic weighing apparatus may be automatically changed according to the format. For example, A format is displayed in Japanese, B format is displayed in English, A format is displayed in g or kg, and B format is weight in pounds or ounces. And so on. Specifically, these two types of control programs are stored in the ROM 11 or the like in advance,
It can be easily realized by selecting one of the control programs according to the detected format.

Further, in the above-described embodiment, when the result data file stored in the RAM 12 of the electronic weighing apparatus main body is copied to the FD 9, a control different from a normal MS-DOS copy command is performed. In the MS-DOS copy instruction, if the FD is taken out while data is being written to the FD, all the parts that have been written to the FD will be erased and wasted (actually, The portion written up to the FD is stored in the FD, but the file size of the directory entry becomes "0" and cannot be read.)

On the other hand, in the above-described embodiment, when writing data to the FD, each time data of one cluster is written, the previous file size is written to the directory entry and the electronic balance is written. The RAM 12 of the apparatus main body stores the portion of the work record file to be currently copied to the FD. For this reason, even if the FD is taken out for some reason during the copying of the data to the FD, the data written to the FD can be read later. Also, since the RAM 12 of the electronic weighing apparatus main body stores how much of the data has been written to the FD,
Only the remaining portion can be additionally written to the FD later.

[0045]

As described above, according to the present invention,
Since various types of data can be read / written to / from various personal computers employing FDs having different formats, it is possible to input work reservation data to the FD or to process total data read from the FD. The special effect of being able to do so occurs. Further, since the apparatus itself automatically determines the type of FD format and switches read / write control, the operator does not need to be conscious of the type of FD format at all. Therefore, at the time of reading / writing of the FD, the operator does not need to perform an operation such as key input of the type of the FD format. Further, even if the floppy disk inserted into the floppy disk device is unformatted (unformatted), it is possible to immediately format and write or copy data on the spot. Furthermore, there is an effect that format through the electronic scale device according to the present invention can exchange data between the various personal computers that employ different FD. That is, the electronic weighing device according to the present invention can be used as a data converter between different types of personal computers.
