Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for displaying figures composed of line segments together with characters or symbols on an output device such as a cathode ray tube display or a printer. The present invention relates to a graphic input method that makes it extremely easy to transmit graphics.

Conventionally, in input devices that input characters, symbols, etc., the characters, symbols, etc. are generally converted into 8-bit codes, and this code is sent to a data processing device such as a computer, and the results of data processing are sent to an output device. However, in recent years, it has become necessary to handle figures in addition to characters, symbols, etc., and it is now necessary to divide figures into predetermined figure pieces and create keys, etc. according to these figure pieces. In addition to providing input means for each, a specific code is assigned to each type of graphic element,
In this way, the type of each graphic element is given to the data processing device, and a predetermined graphic is displayed on the output device. However, in such a figure input method, keys must be provided according to the type of figure element, which has the disadvantage of increasing the number of keys, and in order to avoid the increase in the number of keys. In this method, a separate control key is provided, and the key indicating the type of graphic element and the control key must be operated at the same time, resulting in a troublesome input operation.

Furthermore, since codes are assigned depending on the type of graphic element, the number of types of codes increases, resulting in a disadvantage in that there are restrictions on code allocation. The present invention aims to fundamentally eliminate such drawbacks of the conventional art, and provides an extremely rational graphic input method that allows predetermined continuous shapes to be given as input data by simply providing a specific graphic input means. The present invention provides a method.

Hereinafter, details of the present invention will be explained with reference to figures showing examples.

FIG. 1 is a block diagram showing the system configuration to which the present invention is applied, and the keyboard KB has a general character key group C.
In addition to K being provided as a character input means, a single figure key FK is provided as a specific figure input means, and by operating these keys, a code corresponding to the type of key is generated, and a code is generated according to the type of key, The data processing device DP is given to the data processing device DP such as the
After performing predetermined data processing by storing the code given to the attached memory MM or reading it out, the code is sent to the output device 0E such as a cathode ray tube display device or a printer, and the code is read out. Characters, symbols, figures, etc. corresponding to the image are displayed in a predetermined format.

Note that the data processing device DP accommodates a transmission line L, through which codes are sent and received to and from the other party's data processing device or terminal device.

In addition, the display on the output device 0E is performed sequentially and serially according to the operation of the character key group CK on the keyboard KB, and is shown as horizontal rows, but when a predetermined number of digits is reached, a line break is automatically performed. The characters are input sequentially and serially according to the operation of the character key group CK, so the characters are displayed according to the order of input. The upper row and column are self-determined, and this determines the address of the character indicated by the row and column.

Therefore, characters or symbols, etc. corresponding to the operation of the character key group CK are generated as a code and immediately given to the data processing device DP, but the operation of the figure key FK is treated in the same way, and the figure key FK is The figure instruction code generated by the operation is also inserted into the code string generated in response to the operation of the character key group CK according to the order of operation of the character key group CK and the figure key FK, and the data processing device The display address is determined according to the order of operation of the graphic keys FK.

In addition, a monitor device ME such as a printer is attached to the keyboard KB, and the code sent from the keyboard KB is immediately converted into characters or symbols, etc., and printed on printing paper.

FIG. 2A shows an example of the display on the monitor device ME, and FIG. 2B shows an example of the display on the output device 0F corresponding to A. Each key such as ゛, ``口゛, ``ha,''``2,''``bo,'' etc. is operated in sequence, and in the second line, the space key SK is operated once, and then the figure key FK is operated. is operated repeatedly, and the same operation is repeated on the third and subsequent lines depending on the characters and figures to be input\, then the code corresponding to each key is displayed on the keyboard K according to the order of operation of each key.
The monitor device ME displays A according to the content and order of each code, and continuous figures are constructed according to the input order of the graphic instruction codes through arithmetic processing described later by the data processing device DP. output device 0
E will display B, and in 4.~,
Frres 2-2 to 2-6, indicated by row and column
While special symbols are displayed at 3-2, 4-2 to 4-6, etc., in B, graphic elements each consisting of a line segment are shown at these addresses.

The arithmetic processing performed in the data processing device DP for displaying the graphic element shown in FIG. 2B and its principle are as follows. FIG. 3 shows an example of graphic factors F1 to F4 necessary to show the figure of FIG. DP is the figure factor F
If desired ones are selected from 1 to F4 and combined, figure elements E1 to Ell shown in FIG. 4 are constructed, and if desired ones are selected and arranged from these figure elements E1 to Ell, , any other shapes than those shown in FIG. 2B can be displayed.

In addition, FIG. 4 shows an example of the corresponding code in addition to the graphic elements E1 to E, l. If the figure instruction code generated by operating the figure key FK is EO, then this 4th for code ゛11100000'2 according to
By adding the code consisting of the fourth bit B4 to the first bit B1 in FIG. The code shown is constructed.

That is, for example, the code of figure factors F1 and F2 is ``00''.
0bi and 40010゛, figure instruction code゛ゞ1110
If added to 0000'2, it becomes 611100011'', which can indicate the graphic element E1.

FIG. 5 shows a data processing device DP that performs the above arithmetic processing.
This is a flowchart of the operating state in ``M''.
, n code" is given as an address of m rows and n digits from the keyboard KB, it is determined whether the 8th bit is 8th to 6th bit B6 capi 111" or not. Make the judgment of ゛, and if this is YES, ゛m
-1, n is a figure instruction code? ”, the address on the previous line and in the same digit as the address in the mth row and nth digit is the graphic instruction code E.

If the result is YES, add ``M, nKOOOOOOOOOl'' and add m-1.
, n to 00000100, add the graphic factor F1 in Figure 3 to the m-row, n-digit address, and add the graphic factor F3 in the same figure to the m-1 row, n-digit address. Thus, a code ``1110010bi'' indicating the graphic segment E2 of FIG. 4 is constructed between the address of m rows and n digits and the address of m-1 rows and n digits. Also, regarding this, is ゛M,n-1 the figure instruction code? Based on the judgment of
The address that is the same as and one digit before the m-line, n-digit address is the figure instruction code E.

If the result is YES,
``Add 0000100 to M, n'' and then 6m, n-
Add 00000010 to 1, add the graphic factor F3 to the address of m rows and n digits, and add the graphic factor F2 to the address of m rows and n-1 digit to make the address of m rows and n digits. , m rows and n-1 digit address to form a code "11101010" indicating the figure element E5, and send these codes to the output device 0E. A vertical line is displayed between the address immediately above, and a horizontal line is displayed between the address of m rows and n digits and the address on the left. Therefore, if the data processing device DP stores the codes sequentially given from the keyboard KB in the memory MM line by line and repeats the above-mentioned arithmetic processing based on the contents, a single graphic key can be obtained. F
Figure instruction code E from K. Based on this, a code corresponding to the figure elements E1 to F)11 for indicating a continuous figure is constructed, and it becomes possible to display any figure. FIG. 6A shows the monitor device M using a special operation example of the figure key FK.
B shows the display of output device 0E corresponding to A. In this case, since the operation of the figure key FK for address 2-1 is independent, the data processing device Ignored by the above calculation process in DP,
It does not appear on the display of output device 0E shown in B. Therefore, an erroneous operation of the graphic key FK does not appear in the final output, so reliable display is performed without requiring any particular correction, and operability is improved.

In addition, protruding figures are displayed at addresses 2-6 and 4-2, etc., and if the figure is always formed in a closed loop, addresses 1-6, 2-7 and 3- Detecting that there is no continuity with 2, 4-1,
The display of addresses 2-6, 4-4, etc. may be omitted.

In FIG. 1, when each code is transferred via the transmission line L, the graphic instruction code E is transferred according to the operating order of the graphic keys FK. If it is sent as is and the other party's device performs the same calculation as described above, it becomes possible to divert each code corresponding to the graphic elements E1 to Ell to other uses. Also, instead of using a special one as the first graphic key FK, use one of the character keys CK,
Simultaneous operation with other control keys may also be used as a specific graphic manual, and the line width or single line of the graphic display,
Separate control keys may be provided depending on whether the line is a double line, a dotted line, etc., and a code indicating the type of line may be added in response to the operation of these keys.

In addition, in the display formation of characters, symbols, etc., there is generally a margin between the characters, symbols, etc., and when displaying graphics, it is necessary to display this margin as well, but it is also necessary to display or display the space between lines and digits. Mechanism that can print or characters,
A method may be used in which boundaries between lines and columns are identified using the same font memory as symbols, etc., and line segments are extended and processed. Note that the graphic factor in FIG. 3 may not be set at the center of the rectangular area but may be set at an eccentric point,
In addition to using the keys of the keyboard KB as the input means, a tablet type input device or the like can also be used, and the present invention can be modified in various ways.

As is clear from the above description, according to the present invention, it is not necessary to provide separate input means according to the type of figure element or figure factor, but it is sufficient to simply provide an input means for instructing figure input. The structure and operation of the device become simpler, and only one type of graphical instruction code is required for code transmission, which simplifies the structure of each device and the assignment of codes, and the demand for it is increasing in recent years. Remarkable effects can be obtained when used in the figure input method described in .
