Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a facsimile adapter device, and more particularly to a facsimile adapter device that outputs data obtained from a data terminal to a facsimile receiving device.

(B) Prior Art Conventionally, data from a data terminal such as an electronic notebook is generally displayed on a liquid crystal display device or the like, and in order to print the data, a printer dedicated to the data terminal is required.

(c) Problems to be Solved by the Invention As mentioned above, there is a problem in that a very expensive printer is required to print data from a data terminal.

The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide a facsimile adapter device that enables printing of the data by using facsimile machines that are currently in widespread use.

(2) Means for Solving the Problems The present invention provides an image conversion circuit that obtains an expanded image from data input from a data terminal, an encoding device that obtains an encoded signal from the expanded image, and an encoder that generates an encoded signal from the expanded image. A facsimile adapter device comprising: a communication device for outputting to a facsimile device.

(E) Effect According to the present invention, data input from a data terminal is converted into a coded signal via an expanded image, and this coded signal is output to a facsimile machine. data will be printed.

(F) Embodiment FIG. 1 is a block diagram of a facsimile adapter device according to an embodiment of the present invention.

In the figure, A is a facsimile adapter device, a is a RS
-2 3 2C communication interface, b is a connector for facsimile communication (specifically, a modular jack used to connect a normal facsimile device to a telephone line), 9 is an RS-2 3 Electronic notebook (data terminal) with 2C communication function, 10 is G3FAX
(facsimile machine).

Further, 8 is a central control unit (CPU) that controls the entire facsimile adapter device 8, a first communication device 5 that controls communication with the electronic notebook 9, and a second communication device that controls facsimile communication with the G3 FAX 10. Device 7, electronic notebook 9
Image conversion circuit 1 that obtains an expanded image from data input from
, and an encoding device 6 that obtains an IR encoded signal from the expanded image.

Further, 2 is a data buffer that stores data input from the electronic notebook 9, 3 is a page memory that stores the decompressed image from the image conversion circuit 1, and 4 is a code buffer that stores the encoded signal from the encoding device 6. be.

In this embodiment, communication between the electronic notebook 9 and the first communication device 5 employs an RS-232C communication method using start-stop synchronization and a data length of 8 bits + parity (even number).

Further, the data sent from the electronic notebook 9 is a format in which character data or image data is arranged following data control information.

Next, a case will be described in which data sent from the electronic notebook 9 is printed on A4 size paper using the above-mentioned facsimile adapter device.

The CPU 8 controls the first communication device @ 5 to perform RS-232C communication with the electronic notebook 9 , inputs data from the electronic notebook 9 , and stores the data in the data buffer 2 . Then, the CPU 8 determines whether the data is character information or image information based on the data control information at the beginning of the data, and proceeds to the following processing.

(i) In the case of character information, the CPU 8 reads data from the data buffer 2, uses the image conversion circuit 1 to obtain an expanded image from the character data (specifically, the ), and stores this expanded image in the page memory 3.

By the way, the number of characters in one line is determined by the number of dots in the character font. For example, if a 24 dot x 24 dot character font is provided, the number of characters in one line is 72 characters per line in A4 size.
It becomes a row. Furthermore, the line break of character data may be determined by a line feed code, and the end of character data may be determined by an end code.

Next, the CPU reads the expanded image from the page memory 3 and blackens it, and the encoder 6 obtains an encoded signal from the expanded image (
Specifically, the expanded image stored in the page memory 3 is
The encoded signal is encoded line by line to obtain an encoded signal), and this encoded signal is stored in the code buffer 4.

When the above-mentioned processing is completed, the CPU 8 connects the second communication device 7
, and sends a single frequency (1300Hz) signal to the G3FAX 10 to activate the G3FAXIO. Then, the CPU 8 determines that the second communication device 7
When a response signal is received from CCITT Recommendation T. 30
After establishing a link with the G3FAX10 according to the procedure and completing the training sequence, the encoded signal is read from the code buffer 4, and this encoded signal is transferred to the G3FAXI.
0, and have the data printed by the G3 FAX10. When all transmissions are completed, the CPU 8 transmits the T. Perform the cutting procedure according to Step 30.

In addition, if the number of characters in one line does not reach a predetermined number, white pixels will be added to the expanded image of the line where the number of characters is insufficient, and if the number of characters in one line exceeds a predetermined number, the line will be automatically broken at a predetermined number. It is preferable to do so.

Further, by providing a blank space between lines, the printed image becomes easier to read.

(ii) In the case of image information, the CPU reads data from the data buffer 2, and the image conversion circuit 1 obtains an expanded image from the image data (specifically, the data control information includes the vertical and horizontal lengths of the image data. and resolution, the image conversion circuit 1 obtains an expanded image based on these information), and stores this expanded image in the page memory 3.

Next, the CPU 8 reads the expanded image from the page memory 3, and uses the encoding device 6 to obtain an encoded signal from the expanded image (
Specifically, the expanded image stored in the page memory 3 is
The encoded signal is encoded line by line to obtain an encoded signal), and this encoded signal is stored in the code buffer 4.

When the above-mentioned processing is completed, the CPU 8 connects the second communication device 7
, and sends a single frequency (1300Hz) signal to the G3FAX 10 to activate the G3FAXIO. Then, the CPU 8 determines that the second communication device 7
When a response signal is received from CCITT Recommendation T. 30
After establishing a link with G3FAXIO according to the procedure and completing the training sequence, read the encoded signal from the code puffer 4 and transfer this encoded signal to G3FAXIO.
0, and have the data printed by the G3 FAX10. When all transmissions are completed, the CPU 8 transmits the T. Perform the cutting procedure according to Step 30.

In addition, if the horizontal length is less than the specified size (for example, the horizontal length of A4 size is 216 mm), please position the image in the center and add white pixels to both ends of the expanded image for each line. This makes the printed image easier to read. Also, G
The printing resolution of 3FAX10 is 8 dots/mm x 7.7
line/mm, but for example, the resolution is 8 dots}
/ mm x 3.35 lines/mm, it is preferable to create an expanded image in which the same line is copied into two lines in order to match the resolution.

In the above-described embodiment, communication with the G3 FAX 10 is performed after the encoded signal is stored in the code buffer 4, but the communication can be started at any time.

(G) Effects of the Invention As is clear from the above description, the present invention makes it possible to print data from a data terminal by using currently widespread facsimile machines, so it is extremely difficult to print the data. This eliminates the need for expensive punonta.
