Abstract

PURPOSE:To attain the highly efficient application of a personal computer, etc., by adding a function to a floppy disk device itself to initialize the data on a floppy disk medium. CONSTITUTION:A signal branching part 9 serves as a circuit which branches the interface signals to a personal computer, a terminal equipment, etc., and an interface signal to an initialization control part 10 respectively. In an initialization state of a floppy disk medium, the part 9 performs the control to transfer the read data signal, the write data signal and the control signal between a main control part 1 and the part 10 based on an initializing action instruction received from the part 10. Otherwise the transfer of those signals are carried out between the part 1 and the personal computer, the terminal equipment, etc. Thus a floppy disk device can perform the initialization by itself and meanwhile the personal computer, the terminal equipment, etc., can actuate other programs.

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 that is connected to or built into a personal computer, terminal device, or the like.

[Conventional technology]

In conventional floppy disk devices, the floppy disk medium is initialized when the floppy disk medium is newly used, but generally the floppy disk device is initialized using a connected or built-in personal computer, terminal device, etc. The program is run to initialize the floppy disk medium installed in the floppy disk device.

[Problem to be solved by the invention]

The conventional floppy disk device described above initializes the floppy disk medium by loading the floppy disk medium and running an initialization program using a personal computer, terminal device, etc. Personal computers, terminal devices, etc. that only operate on floppy disks have the disadvantage that other programs cannot be run while the floppy disk medium is being initialized.

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

[Means to solve the problem]

The floppy disk device of the present invention is a floppy disk device that is connected to or built in a personal combinator, a terminal device, etc., and includes an initialization control unit for initializing data on a floppy disk medium, a read data signal, and a pledge data signal. a signal branching section that branches interface signals including signals and control signals to the personal combinator, terminal device, etc. and the initialization control section; and an initialization instruction section that instructs an initialization operation according to an operation of an operator. and an initialization operation display section that displays the initialization operation.

[Example] Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a floppy disk device of the present invention. Further, FIG. 2 is a flowchart showing an example of the initialization operation of the floppy disk medium in the floppy disk device of the embodiment.

Main control unit 1, reading control unit 2, and writing control unit 3 in FIG.
, a read/write head positioning control section 4, a floppy disk medium rotation control section 5, a floppy disk medium loading/unloading mechanical section 6, a read/write operation display section 7, and a read/write head 8, which can be used in conventional floppy disk devices. This is a function that includes

In addition, when reading or writing to a floppy disk medium installed in a floppy disk device based on an instruction from a personal combinator, terminal device, etc., instructions from the personal combinator, terminal device, etc. are sent to the signal branching section 9.
The information is received by the main control unit 1 through the main control unit 1, and the main control unit 1 controls each of the above functions.

On the other hand, when the initialization control section 10 receives an instruction to start the initialization operation from the initialization instruction section 11 (through an operation by the operator), the initialization control section 10 issues an initialization operation display instruction to the initialization operation display section 12 to initialize the initialization operation. In addition to displaying operations, it is also possible to send and receive initialization operation instructions, read data signals, write data signals, and control signals to the signal branching section 9 for initializing the floppy disk medium.

Further, the signal branching section 9 sends interface signals to a personal combinator, a terminal device, etc., and an initialization control section 1.
This is a circuit that branches an interface signal for 0. During the initialization operation of the floppy disk medium, the signal branching section 9 initializes the transmission and reception of read data signals, convolution data signals, and control signals with the main control section l according to an initialization operation instruction from the initialization control section 10. The following describes the initialization operation between the main control section 1 and the personal combiator, terminal device, etc. when the initialization operation is not in progress.

First, in step 21, when the floppy disk medium to be initialized is inserted into the floppy disk device, the floppy disk medium loading/unloading mechanical unit 6 notifies the personal computer through the main control unit 1 and the signal branching unit 9 that the floppy disk medium has been loaded. It is connected to a computer, a terminal device, etc., and the initialization control section 10.

Therefore, in step 22, when the operator presses the initialization instruction switch in the initialization instruction section 11, the initialization instruction section 1
1 sends an instruction to start the initialization operation to the initialization control section 10, so when the initialization control section 10 receives the instruction to start the initialization operation, it sends an initialization operation instruction to the signal branching section 9. Niner.

When the signal branching unit 9 receives the initialization operation instruction, the signal branching unit 9 sends read data signals, write data signals, and control signals that are buttons so that they can be transmitted and received between the main control unit 1 and the personal computer, terminal device, etc. Switching is performed so that transmission and reception can be performed between the main control section 1 and the initialization control section 10. In this state, the floppy disk device is being used by a personal computer, terminal device, or the like.

Further, in step 23, the initialization control section 10 performs an initialization process in the initialization display section 12 so that the read/write data signal, write data signal, and control signal can be transmitted and received with the main control section 1. The indicator lights up and initialization control starts.

Then, in step 24, the initialization control unit 10 reads the type information stored in the installed floppy disk medium because there are various types of floppy disk media currently on the market, and it is necessary to identify the type. for,
The signal branching section 9 sends an instruction to the read/write head positioning control section 4 through the main control section 1 to position the read/write head 8 at the position where the type information of the floppy disk medium is stored. , main control section 1
, the type information is read through the signal branching section 9.

If there is no error in reading the type information in step 25, in the next step 26, the initialization control unit 10 identifies the type of the floppy disk medium installed based on the read type information, and outputs a signal. The branching section 9 sends an instruction to the write head positioning control section 4 through the main control section 1, and while positioning the reading 15/filling head 8, sends initialization data to the writing control section 3, Starting from 8, initialization data is sequentially written in a format suitable for the type of floppy disk medium. When the writing of the initialization data is completed, in the next step 27, the initialization control section 10 turns off the lit initialization indicator of the initialization operation display section 12, and instructs the operator to initialize the floppy disk medium. Informs you that it has finished correctly.

Therefore, in the next step 28, when the operator ejects the floppy disk medium, the floppy disk medium loading/unloading machine section 6 sends a signal to the main control section 1 and the signal branching section 9 to indicate that the floppy disk medium has been removed. Initialization control unit 1 through
Send to 0.

When the initialization control section 10 is informed that the floppy disk medium has been removed, the initialization control section 10 sends an instruction to the signal branching section 9 to end the initialization operation. Signal branch 9
When receiving the instruction to end the initialization operation, the main control unit 1 transmits and receives read data signals, write data signals, and control signals that have been performed between the main control unit 1 and the initialization control unit 10.
Switch to enable transmission and reception between the computer and the burner computer or terminal device.

On the other hand, in step 25, when an error is detected in the type information read by the initialization control unit 10 while reading the type information of the floppy disk medium, in step 29, the initialization control unit 10 The initialization operation indicator on the operation display section 12 is changed from a lit state to a blinking state, and the operator is informed that the floppy disk medium cannot be correctly initialized, and the initialization operation is stopped. Therefore, in step 30, when the operator removes the floppy disk medium, the floppy disk loading/unloading machine section 6 sends a message to the main control section 1 and the signal branching section 9 indicating that the floppy disk medium has been removed.
The information is sent to the initialization control section 10 through the .

Then, in step 31, when the initialization control section 10 is informed that the floppy disk medium has been ejected, the initialization control section 10 turns off the flashing initialization operation indicator on the initialization operation display section 12. At the same time, an instruction to terminate the initialization operation is sent to the signal branching section 9. When the signal branching unit 9 receives the instruction to end the initialization operation, the signal branching unit 9 transfers the transmission and reception of read data signals, write data signals, and control signals that have been performed between the main control unit 1 and the initialization control unit 10 to the main control unit 1 and the personal computer. Switch to enable transmission and reception with combiators, terminal devices, etc.

〔Effect of the invention〕

As explained above, in the 70 disk drive of the present invention, since the floppy disk drive itself is provided with a function to initialize data on the floppy disk medium, the initialization program can be run on a personal combiator, a terminal device, etc. Since the data on the floppy disk medium can be initialized by the floppy disk device alone, this has the effect that a personal computer or the like can be used efficiently.

For example, when you are running an arbitrary program on a personal computer or terminal device, and it becomes necessary to initialize the floppy disk medium, insert a 70 floppy disk medium into the floppy disk device and initialize it. The advantage is that initialization can be performed simply by pressing a switch.
