Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a floppy disk device, and particularly to a floppy disk device connected to or built into a personal computer or terminal device.

[Conventional technology]

Conventional floppy disk devices are used to create multiple copies of the same data on floppy disk media for storage purposes, etc., and are generally used in personal computers or terminals that have 12 floppy disks connected or built-in. A device or the like is used to operate a program for copying data on a floppy disk medium, and data is copied from a copy source floppy disk medium mounted on each of two floppy disks to a copy destination floppy disk medium.

[Problem to be solved by the invention]

The conventional floppy disk device described above is a floppy disk device connected to or built into a personal computer, terminal device, etc.
A copy source floppy disk medium and a copy destination floppy disk medium are respectively installed in a 70-speed disk device, and the data on the floppy disk medium is copied by running a copying program on a personal computer or terminal device, etc. Personal computers, terminal devices, etc. that operate only with a single program have the disadvantage that other programs cannot be operated while data is being copied from a floppy disk medium.

Furthermore, in personal computers, terminal devices, etc. that operate with multiple programs, it is possible to run a copy program and any other arbitrary program in parallel, but both programs have the disadvantage that the processing time is long. .

a signal composite component that branches an interface signal including a write data signal and a control signal to the personal computer, terminal device, etc. and the copy control unit; and a copy instruction unit that instructs the copy control unit to perform a copy operation; and a copy instruction section that displays operations.

〔Example〕

Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the inventive floppy disk device. FIG. 2 is a flow chart showing an example of the operation of copying data on a floppy disk medium in the floppy disk device of this embodiment.

Main control unit 1, reading control unit 2, and writing control unit 3 in FIG.
, read/write head positioning control section 4, floppy disk medium rotation control section 5, floppy disk medium attachment/detachment mechanical section 6, read/write operation display section 7, read #
)/write head 8 is a function also included in conventional floppy disk devices.

Reading or writing to a floppy disk medium installed in a floppy disk device based on an instruction from a personal computer or terminal device, etc., is carried out by a signal branching section 9.
The main control unit 1 controls each of the above functions.

On the other hand, when the copy control section 10 receives an instruction to start a copying operation through the operation of the operator, the copying control section 10 issues a copying operation display instruction to the copying instruction section 13 to display the copying operation. It is possible to send and receive copy operation instructions for reading or writing data on the floppy disk medium, read data signals, write data signals, and control signals to and from the signal branching section 9. Note that the copy instruction section 13
There are a copy operation indicator (2) that displays the read operation of the copy source floppy disk medium and a copy operation indicator (2) that displays the write operation of the copy destination floppy disk medium.

Further, the signal branching section 9 is a circuit that branches an interface signal for a personal computer, a terminal device, etc., and an interface signal for the copy control section 10. During the copying operation, the signal branching section 9 controls the copying control section 10.
The transmission and reception of read data signals, write data signals, and control signals are controlled between the main control unit 1 and the copy control unit 10 according to copy operation instructions from the main control unit 1. Control is performed between personal computers, terminal devices, etc.

Next, the copying operation of this embodiment will be explained based on FIGS. 1 and 2.

First, in step 21 of FIG. 2(a), when the copy source floppy disk medium is loaded into the floppy disk device, the floppy disk medium loading/unloading mechanical section 6 detects that the floppy disk medium is loaded. The signal is connected to a personal computer, a terminal device, etc., and a copy control section 10 through a signal combining and branching section 9 .

Therefore, in step 22, when the operator presses the copy instruction switch in the copy instruction section 12, the copy instruction section 12
Since an instruction to start a copying operation is sent to the copying control section 10, when the copying control section 10 receives the instruction to start a copying operation, it sends a copying operation instruction to the signal branching section 9.

Then, when the signal branching unit 9 receives the close-up operation instruction,
Read data signals, write data signals, and control signals that can be transmitted and received between the main control unit 1 and personal computers, terminal devices, etc. can be transmitted and received between the main control unit 1 and the copy control unit 10. Switch as follows. In this state, the floppy disk device is being used by a personal computer, terminal device, or the like.

Further, in step 23, the copy control unit 10 mainly transmits and receives read data signals, write data signals, and control signals.
11I Copy instruction section 1
Light up the copy operation indicator (3) and start the copy operation.

Then, in step 24, since there are various types of floppy disk media currently available on the market, it is necessary to identify the type. In order to read, an instruction is sent to the read/write head positioning control section 4 through the signal branch section 9 and the main control section 1, and the read/write head 8 is positioned at the position where the type information of the floppy disk medium is stored. , the type information is read through the reading control section 2, the main control section 1, and the signal branching section 9.

Then, in step 25, if there is no error in reading the type information, in the next step 26, the copy control unit 10 converts the read type information of the copy source floppy disk medium into the type information of the copy destination floppy disk medium. It is stored in the storage unit 11 for comparison.

In addition, in steps 27 and 28, the copy control unit 10 identifies the installed floppy disk medium based on the read type information, and sends the read/IF recording head through the signal synthesis branch unit 9 and the main control unit 1. An instruction is sent to the positioning control section 4 to position the read/write head 8, and then copy data is sequentially read through the read control section 2, main control section 1, and signal branching section 9, and stored in the storage section 11.

Then, when reading of the copy data is completed, step 2
If there is no error in reading the copy data in step 9, in the next step 30, the copy control section 10 turns on the copy operation indicator ■ of the copy instruction section 13, and instructs the operator to read the copy source floppy disk medium. Notifies that reading of copy data has been completed correctly.

Therefore, in step 31, the operator takes out the copy source floppy disk medium from the floppy disk device, and in step 32 of FIG. 2(b), installs the copy destination floppy disk medium. The copy control unit 10 informs the main control unit 1 that the previous floppy disk medium has been inserted through the signal branching unit 9.
It goes to. .

Then, in step 33, when the copy control unit 10 is informed that the copy destination floppy disk medium has been installed, the copy control unit 10 turns off the copy operation indicator ■ of the copy instruction unit 13, and in step 34, the copy destination floppy disk medium is inserted. The type information of the medium is read using the same procedure as for reading the type information of the copy destination floppy disk medium.

Then, in step 35, if there is no error in reading the type information, in the next step 36, the read type information of the copy destination floppy disk medium is stored in the storage unit 11 as the type information of the copy source floppy disk medium. If they match, the next step is to write the copy data to the copy destination floppy disk medium. Note that the control procedure when the type information does not match will be described later.

Therefore, the copy control section 10 sends an instruction to the read/write head positioning control section 4 through the signal synthesis branch section 9 and the main control section 1 to position the read/write head 8 while storing the copy data in step 37. At step 38, the signal is sent to the write control section 3 through the signal branching section 9 and the main control section 1, and the read/write head 8
The files are sequentially written to the copy destination floppy disk medium.

Then, when writing of the copy data is completed, step 3
At step 9, the copy control unit 10 reads the copy data from the copy destination floppy disk medium in the same way as it reads the copy data from the copy source floppy disk medium, and at step 36, the copy control unit 10 reads the copy data from the copy destination floppy disk medium. If not, step! In step 7, the copy data is compared with the copy data stored in the storage unit 11, and if they match, in step 118, the copy operation indicator ■ of the copy instruction unit 13 is turned off to indicate that the copy operation has been completed correctly. inform the person. Note that the control procedure when the copy data does not match when compared will be described later.

Further, in step ii9, when the operator takes out the copy destination floppy disk medium, the floppy disk medium loading/unloading machine section 6 notifies the main control section 1 and the signal branching section 9 that the copy destination floppy disk medium has been removed. The information is transmitted to the copy control unit 10 through the

When the copy control unit 10 is informed that the copy destination floppy disk medium has been ejected, the copy control unit 10 issues an instruction to the signal branching unit 9 to terminate the copy operation. Signal branch 9
When receiving the instruction to end the copying operation, the main controller 1 and the personal computer, terminal device, etc. Switch so that you can send and receive data to and from .

On the other hand, in step 25 or step 29, when reading the type information of the copy source floppy disk medium or reading the copy data, if an error is detected in the type information read in the copy control unit 10 or in the copy data, step 40 , the copy control section 10 changes the copy operation indicator (2) of the copy instruction section 13 from a lit state to a blinking state, informs the operator that the copy operation cannot be performed correctly, and cancels the copy operation.

Therefore, in step 41, when the operator removes the copy source floppy disk medium, the floppy disk medium loading/unloading machine section 6 notifies the main control section 1 and the signal branching section 9 that the copy source floppy disk medium has been removed. The information is transmitted to the copy control unit 10 through the

Therefore, in step 42, when the copy control section 10 is informed that the copy source floppy disk medium has been ejected, the copy control section 10 turns off the blinking copy operation indicator (■) of the copy instruction section 13. At the same time, an instruction to end the copying operation is sent to the signal branching section 9. When the signal branch 9 receives the instruction to end the copying operation, the signal branch 9 transfers the transmission and reception of read data signals, write data signals, and control signals that have been performed between the main control section 1 and the copy control section 10 to the main control section 1. and a personal computer, terminal device, etc.

On the other hand, in step 35 or step 36, when reading the type information of the copy destination floppy disk medium or reading the copy data, the copy control unit 10 reads,
If an error is detected in the type information or copy data,
If a mismatch is detected when the type information or copy data read in step 36 or step 37 is compared with the copy source i-specific information or copy data stored in the storage unit 11, in step 43, copy control is performed. Part 10
Then, the copying operation indicator (3) of the copying instruction unit 13 is changed from a lit state to a blinking state, and the operator is informed that the copying operation cannot be performed correctly, and the copying operation is stopped.

Therefore, in step 44, when the operator ejects the copy destination floppy disk medium, the floppy disk medium loading/unloading machine section 6 sends a message to the main control section 1, the signal branching section 9 to the copy control unit 10.

Therefore, in step 45, when the copy control section 10 is informed that the copy destination floppy disk medium has been ejected, the copy control section 10 turns off the blinking copy operation indicator (■) of the copy instruction section 13. At the same time, an instruction to end the copying operation is sent to the signal branching section 9. Signal branch 9
Upon receiving the instruction to end the copying operation, the main controller 1 transmits and receives the read data signal, write data signal, and control signal between the main controller 1 and the copy controller 10. Switch so that you can send and receive data to and from .

〔Effect of the invention〕

As explained above, the floppy disk device of the present invention provides the floppy disk device itself with a function to copy data on a floppy disk medium, so that it can copy data from a floppy disk without running a copy program on a personal computer or terminal device. Since the device can copy data on a floppy disk medium by itself, it has the effect that personal computers, terminal devices, etc. can be used efficiently.

For example, if you are running an arbitrary program on your personal computer or terminal device, and you need to copy data from a floppy disk, you can use the floppy disk. It has the advantage of being able to make copies simply by attaching it and pressing the copy stopper switch.
