Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the transmission and reception of information exchange codes using a storage device that stores facsimile encoded information.

Traditionally, facsimiles are handwritten documents, printed documents,
It has been used as a device for transmitting documents containing graphics as facsimile signals to remote parties.
With recent advances in technology, even if a facsimile receiver receives character information represented by a character code, if the receiver is equipped with a character generator, the character information can be collated with the contents of the character generator. Facsimile signals can now be easily obtained from character codes. Therefore, in addition to outputting a facsimile signal to a record, a facsimile receiver can also output a received character code to a record. Taking advantage of this fact, some cases have begun to be seen in which character codes output from computers are received by facsimile.

On the other hand, on the sending side, in order to create a document represented by a character code and transmit it to a remote party by facsimile, the document must first be created using a document creation device such as a keyboard, and then output as a hard copy on paper. After that, send it to the facsimile transmitter,
You must either convert it into a facsimile signal and then send it, or connect your document creation device to a facsimile transmitter and send it to the other party as a character code.

Therefore, the facsimile device requires a document creation device such as a keyboard, which increases the cost of the device. FIG. 1 is a block diagram of a conventional facsimile device used to send character codes such as characters. 1 is a facsimile reading section/recording section, 2
3 is an encoding section/decoding section, 3 is a signal control section, 4 is a communication section, 5 is a storage section, 6 is an operation section, and 7 is a document creation device section. 8 is a conventional facsimile machine.

The operation shown in FIG. 1 will be explained. When sending a facsimile signal, the original to be transmitted is read by the reading section of the facsimile reading section/recording section 1, and the read signal is encoded by the encoding section of the encoding section/decoding section 2. In order to match the terminal processing speed of the randomly generated encoded information with the communication speed of the communication channel, the encoded information is temporarily stored in the storage unit 5, read out at a speed corresponding to the communication speed, and then communicated. The encoded information is sent from the device section 4 to the communication path. A signal control section 3 manages the processing of facsimile signals and controls the processing of each section 1, 2, 4, 5, and 6. The operation unit 6 is used to select a communication partner, decide to start communication, designate the operation mode of the facsimile machine, and the like.

When receiving a facsimile signal, the communication section 4 receives the facsimile encoded information, and inputs it into the storage device 5 to match the communication speed and terminal speed. The facsimile signal is input into the decoding section 2, the facsimile signal is restored by the decoding section, and the facsimile reading section/recording section of the recording section 1 obtains a received image. When a character code is received, the converter 9 converts the character code into a facsimile signal, and the facsimile signal is output as a hard copy by the recording section of the facsimile reading/recording section 1. Next, when the character code is sent by the device 8, the document creation device 7 is connected to the signal control section 3. The document created by the document creation device 7 is once stored in the storage section 5, as in the case of facsimile, and then sent out to the communication channel via the communication section 4. Therefore, in order to transmit the character code, it is necessary to connect the document creation device 7 to the facsimile device 8, which increases costs.

The present invention has been made to solve these drawbacks, and uses a recording medium and writing or reading from the recording medium as a storage unit for facsimile encoded information used to match terminal processing speed and communication speed. Using a device that can be separated from the storage control device to be used, such as a floppy disk device, magnetic tape device, magnetic card device, paper tape device, etc.
By configuring so that a recording medium created by a document creation device installed in a remote location separate from the facsimile device can be used, the recording medium can be used without connecting the document creation device to the facsimile device. This feature is characterized in that a character code can be sent via the computer.

Examples will be described in detail below.

FIG. 2 is a block diagram showing an embodiment of the present invention, in which the same names and symbols are used for the same parts as in the conventional device shown in FIG. The storage unit 15 stores recording media such as floppy disk devices, magnetic tape devices, magnetic card devices, paper tape devices, etc. (floppy disks, magnetic cards...
etc.) that can be separated from the storage device and taken out or attached to it freely. Operation unit 16
is an operation section for dialing the other party and specifying the mode of the terminal in order to connect with the communication partner, and uses the storage section for information from the reading section of the facsimile reading section/recording section 1. mode and
There are operation buttons and the like that allow the operator to separately instruct the mode in which the recording medium stored with character code information by an external document creation device etc. not connected to the facsimile device 18 is used in the storage section. A control device is provided to distinguish between transmission/reception of character codes, transmission/reception of facsimile signals, and the like.

FIG. 3 is a diagram for explaining the operation of writing facsimile read information to the floppy disk device 154 when the floppy disk device 154 is used in the storage section 15 of FIG. Direct memory access 32 to microprocessor 3
1 to write to the floppy disk device 154, the processor 31 requests the facsimile reader 1 to write to the floppy disk device 154.
Issue a read start command to. The read data is redundancy suppressed encoded by the encoder 2 and input into the buffer memory 151. buffer memory 15
If 1 does not overflow, the formatting device 152 adds the sequence number and address number of the data to be written to the floppy disk as a header and converts it into a signal format of a predetermined length.
After converting the signal into a parallel signal, it is written to the floppy disk device 154 via the system bus 2. When the buffer memory 151 overflows, a request to stop reading is issued to the processor 31, and the buffer memory 151 is controlled.

In order to transmit the character code, a recording medium for that purpose is created. FIG. 4 is a diagram showing a case where the storage device 15' is connected to the document creation device 7 to create a recording medium for transmission using a character code. The storage device 15' is of the same type as the storage device of the storage unit 15 provided in the facsimile device 18, and the recording medium created by the storage device 15' is attached to the storage device 15' of the facsimile device 18. It must be readable. Therefore, the format of the data stored on the recording medium in the storage device 15' is made the same as the format of the data in the storage section 15 of the facsimile device 18. FIG. 5 shows an example of the data format, which consists of a control code 21 and document data 22. Note that the document information may be divided into several pages or several blocks within one page, and a data format as shown in FIG. 5 may be created for each.

Next, FIG. 6 shows the floppy disk device 154.
FIG. 3 is a diagram for explaining an operation of reading and transmitting information. The floppy disk device 154 is equipped with a floppy disk written by the storage unit of the facsimile device 18 when transmitting a facsimile signal, and is loaded with an external document creation device, etc. when transmitting a character code signal. A floppy disk created by was attached. A desired mode designation button on the operation unit 16 is pressed by the operator. First, the direct memory access 32 issues a floppy disk read request to the processor 31. When a request is accepted from the processor 31, the direct memory access 32 accesses the floppy disk device 15.
The data is read directly from the floppy disk to the output port 41 via the system bus 20 by specifying the address of the recording medium No. 4. After the signal from the output port 41 is converted by a parallel-to-serial converter 42, it is sent to a buffer memory 4 for matching the transmission speed.
It can be placed in 3. The contents of the buffer memory 43 are output to the transmission path when there is no overflow. However, when the buffer memory 43 overflows, it issues a request to the control section 3 to stop reading from the floppy disk device 154. Then processor 3
1 issues an instruction to the direct memory access 32 to stop reading from the floppy disk device, and reading is stopped.

As explained above, since the amount of facsimile encoded information is not always constant but fluctuates, it is necessary to match the processing speed of the terminal with the transmission path, and for this purpose storage devices have traditionally been used. However, the present invention uses a storage device in which the recording medium can be separated from the storage device, and
This device has a mode that uses character codes, and by creating a recording medium for character codes using an external document creation device, etc., and using that recording medium, it is possible to send messages to remote parties based on character codes. Document transmission becomes possible. Further, in this case, there is no need to connect a document creation device such as a keyboard to the facsimile device, and the facsimile device is superior to conventional facsimile devices for sending characters in terms of economy.

Furthermore, the information obtained by the storage device can be held as a recording medium, and multiple copies of documents with the same content can be made.
