Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile device, and more particularly to a facsimile device that prints out calligraphic information from a connected computer onto recording paper.

[Conventional technology]

In conventional facsimile machines, print data generated for a printer attached to a computer is printed out on recording paper by the facsimile's printer unit via an interface.

[Problem to be solved by the invention]

The above-mentioned conventional facsimile devices have drawbacks such as the size of the print area being different and the shape of the character font being deformed because the line density of the printer attached to the computer and the line density of the printer section of the facsimile are different. .

[Means to solve the problem]

The facsimile apparatus of the present invention includes an interface connected to a computer, and a calculation unit that calculates a converted print position converted into facsimile linear density based on a value calculated from the print position according to an instruction code of the computer inputted from the interface. , a frame memory that stores one page's worth of image information of the linear density; a development unit that reads font data of calligraphy and strokes according to the designated instruction code from the font ROM and writes it into the frame memory; and the frame memory. The printer control unit controls the printer unit to print dot-level print data from the printer.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention.

This embodiment includes a printer control section 9 that prints dot-level print data, a communication control section 10 that sends a band-compressed signal of the dot-level print data to a line,
The image forming apparatus includes a scanner control section 14 that scans a document and generates dot-level print data.

The features of the present invention are that the interface 1 connects to a host computer (not shown) and the printing position specified by the command code from the host machine is set to an address on the frame memory 3 corresponding to the line density of the facsimile. The arithmetic unit 2 to be converted determines whether the instruction code indicates a character font or a ruled line font, and if it indicates a character font, the character is stored in the font ROM.
4 and write it to the address calculated by the calculation unit 2, and when it points to a ruled line font, read it from the corresponding font ROM 4, transform the font so as to guarantee the continuity of the ruled lines, and write it to the address calculated by the calculation unit 2. When the instruction code indicates dot graphic data, the frame memory 3 converts the image data sent as dot graphic data into facsimile linear density and calculates it in the arithmetic unit 2.
a dot graphic development unit 6 that writes to the address of
A kudzu print control section 7 that controls the operations of the font development section 5, dot graphic development section 6, and calculation section 2 and outputs control signals to the facsimile control section 13, and a scanner that outputs dot data from the frame memory 3. A selector 11 selects dot data from the control section 14 or the communication control section 10, and a selector 11 selects dot data from the control section 14 or communication control section 10, and outputs this output from the printer control section 9.
Alternatively, the selector 12 input to the communication control section 10 and the output of the print control section 7 control these selectors and the scanner control section 14. The printer controller 99 includes a facsimile controller 13 that controls the communication controller 10.

Next, the operation of this embodiment will be explained. In the case of this embodiment, the linear density of the printer attached to the host computer is 1.
Print data is output assuming that it is 80LPI. On the other hand, the line density of a facsimile printer is 8 lines/mm.
X 7.7 lines/l1lIII, so if you print as is, it will be 180/203 in the main scanning direction and 1 in the sub-scanning direction.
The calligraphy and drawings are printed out after being reduced at a ratio of 80/196.

Therefore, in the present invention, the printing position of the font and the dot graphic are calculated in the calculation unit 2 using the formulas (1) and (2), respectively, and the corresponding address of the frame memory 3 is output. Xo and YO in formulas (1) and (2) are 1
Indicates the upper left printing position of the font or dot graphic data block on the 80LPI plane, and Xm and Ym are 8
books/mm x 7.7 books/l1lfll Represents the upper left printing position of a font or dot graphic data block on a plane.

If the code specified by the host computer is a character font, the corresponding font data is transferred to the font RO.
When reading from M4, as shown in Figure 2, the upper left of the character is (
The data is expanded onto the frame memory 3 so as to match the addresses calculated using equations 1) and (2).

Next, if the instruction code is a ruled line font, read the corresponding font data from phono 1 to ROM 4 and transfer it onto frame memory 3 so that the upper left of the character matches the address calculated by formulas (1) and (2). When developed, the font is transformed so that it continues with the next ruled line font, as shown in FIG. 3, and is developed onto the frame smori 3.

If the instruction code is dot graphic, the main scanning direction is 203/180 in units of blocks sent at one time.
A linear density conversion of 196/180 in the sub-scanning direction is performed and the block is expanded onto the frame memory 3 so that the upper left corner of the block matches the address calculated using equations (1) and (2), as shown in FIG. .

By doing the above, unshrinkable tiger data is generated on the frame memory 3. When printing out this data, from the computer to the printer 1 to the host 1.
When a local print command is given to the facsimile control section 13 via the control section 7 or when a local print command is given to the facsimile control section 13 from the facsimile operation section,
The facsimile control section 13 connects the selector 11 to the frame memory 3 side and connects the selector 12 to the printer control section 9 side to execute print recording.

In addition, if you want another device to print out, either give a remote print command including the destination phone number from the host computer to the facsimile control unit 13 via the print control unit 7, or use the facsimile control unit to control the facsimile from the facsimile operation unit. When a remote print command including the destination telephone number is given to the facsimile control section 13, the facsimile control section 13 selects the selector 1.
1 is connected to the frame memory 3 side, and the selector 12 is switched so as to connect this output to the communication control section 10.

The communication control unit 10 calls the destination telephone number input from the facsimile control unit 13, connects the line, and then outputs the bandwidth-compressed prints 1 to 1 from the frame memory 3.
Output the data to the line.

When there is no print command from the host computer, the facsimile control section 13 switches the selector 11 to the scanner control section 1.
4 or the output of the transmission control section 13 is connected to the selection side to operate as a normal facsimile machine.

Here, the interface 1 is, for example, an interface using Centronics. In addition, the printer 1 to commands input to the computer to the host 1 are, for example, the Microsoft disk operating system (Mic
rosoft Disk Operating System
tem, MS-DO3) is a PRINT command, and the microcomputer operating system (Mon1
torcontrol program for mi
In crocomputer, CP/M), this is a PIP instruction. The print command code inputted from the host computer is used to, for example, start printing, horizontal/vertical tabs, line breaks, specify printing characters, and control character spacing and dot graphic printing.

〔Effect of the invention〕

As explained above, the present invention converts the printing position into the line density of the facsimile in accordance with the instruction code of the computer and generates dot-level calligraphic information developed from the font ROM, thereby allowing the printer section of the facsimile to print. It is possible to eliminate the problem of deformation of the print area of calligraphy and drawings and the shape of character fonts.

It is a front view.
