Description

Detailed Description of the Invention [Purpose of the Invention (Field of Industrial Application) The present invention relates to an information transmission device capable of transmitting recorded information on an information recording medium between a plurality of terminals connected to a public line. .

(Prior Art) In recent years, computer and word processing communications that use public telephone lines to mutually transmit various types of information between multiple terminals have become popular.

Such computers, word processors, etc. are mainly used for the use of other application software and for the input work inherent to word processors, and are not dedicated devices for communication. Therefore, for example, when attempting to transmit text information to another word processor, etc., it is necessary to take the following steps.

First, for example, if you are currently editing a text file,
Finish this work once.

After this, the user of the other terminal is notified that the text information will be sent from now on. As a result, if the destination word processor or the like is currently editing a text file, the process will be temporarily terminated.

Thereafter, both terminals are enabled to transmit and receive information at the same time, and information transmission begins.

Then, wait for the transmission to end, and then re-execute the interrupted work.

(Problem to be solved by the invention) However, as long as public lines are used, there is a natural limit to the speed of information transmission, and no matter what kind of text information or binary information is transmitted, it will take a considerable amount of time. . Moreover, during this transmission, both terminals are in a state where no human power is accepted, and it is impossible to use other application software or perform input operations that are typical of word processing.

Therefore, for example, when transmitting a relatively large text file, there is a problem in that both word processors cannot be used for a long time.

Furthermore, in addition to the above-mentioned problem, information transmission between terminals of different models is difficult, except for some models in a superior-lower relationship, because the formats of floppy disks and the like are different. For this reason, conventionally it was necessary to use a host computer.

Therefore, an object of the present invention is to provide an information transmission device that can mutually transmit information regardless of the difference in format of information recording media.

[Configuration of the Invention] (Means for Solving the Problems) The configuration of the present invention for achieving the above object will be explained.

The information transmission device on the sending side is an information transmission device that can mutually transmit recorded information on the information recording medium in each terminal and its format information between multiple terminals connected to a public line, and The apparatus includes an analysis means for analyzing the format of the information recording medium in the terminal, and a sending means for sending the analyzed format information and recorded information to another specific terminal. In this case, it may be equipped with a compression means for compressing the analyzed format information and recording information.

In addition, the information transmission device on the receiving side includes a temporary recording means for temporarily recording the transmitted information, and a formatting means for formatting the information recording medium based on the format information of the recorded information. , and a writing means for writing temporarily recorded information onto a formatted information recording medium.

In this case, as long as the recorded information and its format information are compressed, it may be provided with a decompressing means for decompressing the temporarily recorded recorded information.

Furthermore, an analysis means for analyzing the format of the information recording medium in one terminal, a transmission means for transmitting the analyzed format information and recorded information to another specific terminal, and a transmission means for temporarily transmitting the transmitted information. A temporary recording means for recording, a formatting means for formatting an information recording medium based on format information among the recorded information, and an instruction to write temporarily recorded information on the formatted information recording medium. It may also have a writing means. In this case as well, a compression means for compressing the format information and recorded information analyzed by the analysis means and a decompression means for decompressing the transmitted compressed recorded information temporarily recorded in the temporary recording means are provided. Good too.

(for production) The operation of the present invention having the above configuration will be explained.

First, the analysis means analyzes the format of the information recording medium in one terminal. Then, the recorded information together with the analyzed format information is sent to another specific terminal by the sending means.

In this case, as long as it is equipped with a compression means, the information to be sent may be compressed and sent.

Information transmitted from other terminals is temporarily recorded in the temporary recording means. The formatting means formats the information recording medium based on the format information among the recorded information. Then, the writing means writes the temporarily recorded information onto the formatted information recording medium. In this way, information can be mutually transmitted regardless of the difference in format of the information recording medium.

(Example) Hereinafter, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an information transmission device as an example.

The information transmission device shown in FIG. 1 includes a modem 1 that demodulates and modulates information to be transmitted and received, a public line interface 2 that performs matching of information input and output from other terminals or computers via the modem 1.

The temporary recording means 3 includes a 5csr adapter 4 and a 40M
The memory disk 5 includes a fixed disk 6 having a capacity of B and a memory disk 5 including a RAM or the like having a capacity of 2 MB.

Among these, the memory disk 5 has a function as a buffer memory for temporarily recording a predetermined amount of information input via the modem 1 or the like and sequentially transferring the information to the fixed disk 6.

The fixed disk 6 receives information from the memory disk 5 as described above, temporarily records this information, and also compresses the control file 30 for the entire device and the information recorded on the floppy disks 9 to 11. A compressed file 25 that decompresses the information from the memory disk 5 if it is compressed, an analysis file 31 that analyzes the format of the floppy disks 9 to 11, which are transmitted from one terminal. A processing file 28 for processing recorded information, a retransmission file 27 for retransmitting this processed recorded information to another specific terminal, and analyzed format information and recording information.
A sending file 29 for sending to another specific terminal, a format file 32 for formatting an information recording medium based on format information, and the like are recorded.

The PRG memory 7 is a memory in which files 25 to 32 read from the fixed disk 6 as necessary reside.

The floppy disk controller group 8 includes a floppy disk controller 2 that drives floppy disks 9 to 11 having different media sizes of 3.5 inches to 8 inches, respectively, and writes/reads information.
1 to 23.

Based on each of the files 25 to 32 recorded on the fixed disk 6 or PRG memory 7, the CPU 20
an analysis means for analyzing the format of a floppy disk in one terminal; a compression means for compressing the analyzed format information and recorded information; a sending means for sending the compressed information to another specific terminal; a decompression means for decompressing recorded information temporarily recorded on the recording means; a formatting means for formatting the information recording medium based on format information of the recorded information; each as a writing means for writing information stored in the terminal, a processing means for processing the recorded information transmitted from one terminal, and a retransmission means for retransmitting the processed recorded information to another specific terminal. It is equipped with functions.

For example, if a text file created by another word processor or the like is recorded on the floppy disk 9 inserted into the floppy disk controller 21, the CPU 20 as the analysis means determines the format, for example, the number of cylinders and the number of tracks as ID information. It has a function to analyze the number of sectors, sector length, etc., and register the format in a reference table format.

By the way, FIGS. 2(a) and 2(b) are perspective views showing the external configuration of the present device.

The components shown in FIG. 1 are housed in a case 33, and a portion of the floppy disk controllers 21 to 23, a display section 14, and an input section 13 are arranged in an orderly manner on an operation surface 33a. Incidentally, 36 is an external connection section consisting of various connectors.

Operation of the information transmission device configured as described above.

The effect will be explained with reference to FIG. 3 as well.

When you press the reset switch (not shown),
The control file 30 recorded on the fixed disk 6 is read out and transferred to the PRG memory 7. Then, the control file 30 self-diagnoses the status of each part of the device and enters the activated state.

Sending operation> When the control file 30 is activated and a floppy disk is inserted into any of the floppy disk controllers 21 to 23, a message “Please press the start button” is displayed on the display unit 14. .

When the operator presses the start button according to these instructions,
The CPU 20 as a format analysis means gives a read signal to the floppy disk controller (21 to 23) into which the floppy disk is inserted, and the floppy disk controller reads the ID information of the floppy disk.

Then, the CPU 20 creates a reference table based on this read ID information. This is format information.

Next, the CPU 20 sequentially reads information recorded on the floppy disk track by track while referring to the reference table.

This read information is once transferred and written to the memory disk 5 together with the format information.

The recording information and format information written to the memory disk 5 as described above are stored in the CP as a compression means.
High-density compression is performed by U20.

When the information to be transmitted is compressed in this way, identification information indicating that it is a compressed file is also added. Such compression can significantly reduce the time required for transmission. Note that the recording information and format information do not need to be compressed unless necessary.

When the compression is completed, a message "Please enter the destination" is displayed on the display unit 14.

When the destination is input from the input section 13 in accordance with this message, the CPU 20 serving as a sending means places a telephone call to the terminal of the destination.

Then, when a data link is established between both terminals, the CP
Based on the transmission request signal from the destination terminal, U20
The compressed recording information and format information described above are sent. In this case, if a data link is not established, the compressed recording information and format information are temporarily written to a fixed disk, and are sent to the destination terminal automatically and at regular intervals until a data link is established. I'll have to call.

Receiving Operation> When compressed recording information, format information, etc. are received via the modem 1, these information are sequentially stored in the memory disk 5 and transferred to the fixed disk 6 in predetermined capacity units.

Once all record and format information has been received,
Display unit 14 shows “File (information) has arrived”
is displayed. In this way, it is possible to eliminate the need for operator monitoring and reception operations at the terminal on the receiving side as well.

When the operator confirms the display contents on the display section 14 and presses a confirmation button (provided in the input section), the display section 14
A message such as ``Please insert a 3.5-inch floppy disk'' is displayed.

Following this instruction, the operator inserts a 3.5-inch floppy disk into the floppy disk driver 21 and specifies the file to be written.

Then, the CPU 20 as a formatting means formats the inserted floppy disk based on the format information.

Next, the CPU 20 as the decompression means uses the fixed disk 6
Among the files recorded in , only the specified file is decompressed.

Then, the CPU 20 as a writing means writes the recorded information temporarily recorded on the fixed disk 6 to the formatted floppy disk.

Here, it is assumed that the terminals 37 to 39 are connected to the public line as shown in FIG. The following description assumes that the data is sent to the terminal 38.

When the terminal 38 receives the information A, the CPU 20 as a processing means processes the received information A by adding, for example, information A'. This processed information A+A' is
The CPU 20 serving as a retransmission means retransmits information A+A' to the terminal 38 based on the retransmission information.

According to the apparatus of this embodiment described in detail above, data can be transmitted and received regardless of how the floppy disk is formatted and regardless of its type. Furthermore, the operator is not constrained during transmission or reception.

It should be noted that the present invention is not limited to the above embodiment,
Various modifications can be made within the scope of the gist.

In the embodiments described above, a floppy disk was used as an example of the information recording medium, but the present invention is not limited to this, and the same applies to IC cards, optical disks, magneto-optical disks, and the like. In this case as well, the same effects as in the embodiment described above can be obtained.

[Effects of the Invention] According to the present invention described in detail above, it is possible to provide an information transmission device capable of mutually transmitting information regardless of the difference in the format of the information recording medium.
