Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of printing an electronic whiteboard equipped with an output printer capable of printing.

In an electronic blackboard equipped with an output printer capable of printing, characters and tooth shapes displayed on the display surface are each displayed in a size within the range of the standard output print width and length of the output printer. There has been no disclosure of a technique for printing paper of a printer in a variable size within the range of the standard output print width and length of the output printer.

C. Problems to be Solved by the Invention In the conventional technology, as mentioned above, characters are displayed on the display screen within the range of the output print width and length,
Because it is not possible to print figures on paper of an output printer in a variable size within the range of the standard output print width and length of the output printer, on one display surface the standard output print width and length of the output printer cannot be printed. Each of the characters and graphics displayed within the size range can be printed on the paper of the output printer in its size, or each of the characters and graphics displayed on the display surface of the above size can be printed on the paper of the output printer. The technical problem of the present invention is to solve the above-mentioned drawbacks of the prior art, which had the drawback of not being able to print at a size suitable for smaller paper.

2. Means for Solving the Problem In order to achieve the above-mentioned technical problem, the present invention sets a predetermined position based on the standard output print width of the output printer in the longitudinal direction of the display surface, and A single character figure with a size within the range of the standard output width and length of the output printer is displayed at each position, and in the main scanning direction, the original main scanning width is limited to the standard output print width of the output printer. In the sub-scanning direction, there is a means for moving the display surface at a speed that matches the standard printing width of the output printer, and a technical means for changing the writing pulse signal to the output printer in accordance with the standard print width of the output printer. shall be.

E. The output printer is displayed at a predetermined position on the operation display screen, and the movement speed of the display surface and the writing pulse signal to the output printer are changed to match the standard pre-drive width and length of the output printer. As characters and shapes of width and length,
Each is printed on the paper of the output printer.

Example 1 is a driving roller shaft, 2 is a roller shaft for direction change, and 3 is a driving roller shaft.
4 is an endless sheet having display surfaces 3' and 3', 4 is a box-shaped housing with an opening on one side (the left side in Figure 2), and 5 is an output provided on the bottom of the housing 4. Printer, 6.6'
are a pair of legs provided on the housing 4, and the driving roller shaft is mounted between the side plates 8 and 8' of the housing 4 so that it can rotate slightly above the lower side 7 of the housing 4. A rotating gear 9 is integrally fixed near one end (the front end in FIG. 2) of the rotary shaft. Reference numeral 10 denotes a pulse motor for driving the drive roller shaft. The gear 9 on the shaft 1 is the gear 1 mounted on the side plate 8.
They mesh through 3. The roller shaft 2 for changing the direction is mounted between the side plates 8, 8' so that it can rotate slightly below the upper side of the housing 4. The endless sheet is placed between the roller shaft 2 and the driving roller shaft 1, and the driving roller 1 is rotated by the rotation of the pulse motor 10 through the gears 12, 13 and 9. By rotating, the direction of the endless sheet 3 is changed by a direction changing roller 2, and the endless sheet 3 is moved. Reference numeral 14 denotes an optical system storage case, which is provided inside the upper side of the case 4, and includes a light source 15 and first and second reflecting mirrors 16 and 17. Each is accommodated. 18 is a condensing lens; 19 is a CCD image sensor; They are set in that order. Then, by moving the endless sheet 3, the letters and figures written or pasted on the display surface 3', irradiated with the light v, 15, are reflected by the first and second reflecting mirrors 16. 17. It reaches the CCD image sensor 19 through the condensing lens 18 and is read, and the read character 1 graphic data is transmitted to the output printer 5 and reduced to one side of the reference paper of the output printer 5,
It is ready to be printed. All of the above are similar to known ones.

Reference numeral A denotes an operation panel provided in the housing 4, and this operation panel has a plurality of keys Aa, Aa, Aa, and Aa for specifying write pulse cycles.
Ab and Ac are provided respectively. B is a pulse oscillator, C is a read-only frequency divider, D is a write-only frequency divider, E is a write-only frequency divider, and E is an endless sheet 3.
These frequency dividers C, D and microcomputer E are connected to the operation panel A and the pulse oscillator B, respectively, as shown in the third diagram, and the frequency divider C is connected to the COD.
The output printer 5 is connected via the image sensor 19, the frequency divider is directly connected to the output printer 5, and the microcomputer E is connected to the pulse 10, respectively.

Further, on the display surfaces 3', 3' of the endless sheet 3, an output printer 5 is installed in the longitudinal direction (back and forth direction in FIG. 1).
A predetermined position F based on the standard output print width a of Only characters and figures displayed within the basic output print width a at a predetermined position F are scanned and read, and a pulse signal of the scan reading width is outputted to the output printer 5 via the CCD image sensor 19. It has become. In addition, operation keys Aa and Ab on operation panel A
, by changing the pulse signal written from the frequency divider by instructions from AC, the number of times of writing to the output printer section 5 can be changed. The moving speed of the display surface 3 can be changed according to the endless sheet 3 via a pulse motor 10 by a signal. Therefore, for example, if the size of the display surface 3 is A, which is a known size, and the size of the printing paper is A, and the output printer 5 is for a known A4 size paper, the longitudinal direction of the display surface 3 is the longitudinal direction of the A4 size paper. Set a predetermined position F of the standard output print width a by displaying the index G, and write a letter at that predetermined position with a size within the length range of the standard output print width a and the standard print length b of the A+ version paper. For example, if "Fire Prohibited" is displayed by writing or pasting, and the operation key Aa of the operation panel A is pressed, only the character "Fire" displayed within the range of the reference output print @a is read by that operation. At the same time, a pulse signal having the scanning reading width is outputted to the output printer 5 via the CCD image sensor 19, and at the same time, a signal having the writing pulse width having the reading width is outputted from the frequency divider and written. In response to an instruction signal from the microcomputer E, the display surface 3' moves at the same speed as the paper feed speed of the output printer 5 according to the endless sheet 3 via the pulse motor 10. The character ``Fire'' that is the same size as the character ``Fire'' displayed on surface 3'
It is printed as shown in Figure 4 (a). Therefore,
By providing the output printer 5 with a long roll paper J whose width is the length of the A4 paper H in the longitudinal direction, the characters "No Fire" displayed on the first display surface 3' can be displayed on the long roll. In addition to printing the size on the paper J, the output printer 5 is provided with a cutter for cutting the roll paper, and after printing, the paper is cut by the cutter K. "Prohibited" can be obtained as a single long print. Also, if you wish to print each of the characters displayed in the above-mentioned sizes below a predetermined position on the display surface 3' on A5 paper provided in the output printer 5, you can press the operation key Ab on the operation panel A. . Then, the read pulse signal from the frequency divider C and the pulse signal from the frequency divider with a writing frequency width suitable for A5 size paper are input to the output printer 5, and the microcomputer E sends the paper to the output printer 5. As a result of inputting a pulse signal suitable for the speed to the pulse motor 10, a desired print as shown in FIG. 4(c) can be obtained. Furthermore, if you want to print the characters displayed in the above-mentioned size on the display surface 3' on a single sheet of A4 size paper of the output printer 5 in the same positional relationship on the display surface 3', you can All you have to do is press the operation key Ae like a known one. Then, the output signals from the frequency divider C and the microcomputer E are inputted to the output printer 5, so that a desired print as shown in FIG. 4(b) can be obtained.

Although the above description has mainly focused on printing the characters displayed on the display surface 3', it is also possible to print the characters instead.

Effects of the Invention According to the present invention, each of the characters and figures displayed on the display surface in a size within the range of the basic output print width and length of the output printer is displayed on the paper of the output printer. Printing can be done easily and reliably within the range of width and length with a simple operation, completely eliminating the drawbacks of conventional electronic blackboards, and printing characters of various sizes. The effects brought about by the use of graphic prints are extremely large.
