Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a control system for a display device that displays variable pitch characters such as alphabetical characters in which the number of display dots differs for each character, as well as variable pitch characters such as stretchable characters in which the number of display dots changes depending on the specification of double-width characters and cow-horn characters. It is related to Tsukuda-shōkubi.

When tabulating tables or the like using a word processor or a personal computer, tab control is possible by inputting a tab code to display characters at a designated tab position. In other words, the tab character is displayed at the specified position by inserting a predetermined number of standard space characters of a size corresponding to the standard column of the display device in front of the tab character. It is. However, when using -1: Kicho odd pitch characters, the character's size and the size of the column do not correspond, so the tab specified position and the display position of the tab specified character; It is difficult to accurately display (print) the characters specified by the tab at the specified position on a display device such as a CRT display or a page printer.For example, as shown in Figure 81111.゛t
As shown, four characters C1 are inputted on the CRT screen, with the character widths of the alphabet letters I, e, etc. being narrower, and the number of dots i being smaller than the number of columns, and seven columns from the beginning of the line (
When the tab mark C2 is set in advance and the character YC6 to be input after the character C1 is specified as a normal tab, the characters C1... are calculated as one column, and the characters before the character group C6 are calculated as one column. To the two marks C.
By inserting the space character C3, the character group 06 specified by the tab is displayed from the 7th column.
f7? has been completed. However, since the width of the character C1 is narrow, the character position does not correspond to the column position, and the beginning of the character group C6 cannot be displayed in alignment with the position corresponding to the tab mark C2.

This is the same when you use double-width, half-width Okiji characters. ) Even when performing tough printing, etc., the characters specified by the tab cannot be displayed accurately in the specified position, and there is a drawback that the tough machine f flood cannot be sufficiently generated.

S 4 = 7.6 dots) (step 67
). The selecting means 27 selects the auxiliary space character S5 having the number of dots equal to the sum of one of the auxiliary spaces S3 and the remaining space s1, and selects the one-dot data character S5 having the number of dots equal to the auxiliary space S4 of the ability. It is inserted after the CI code data (step 69). Next, one column is subtracted from the standard space column loss N3 calculated by the subtractor 26.1. (Step 70)
, based on this value, standard space characters corresponding to correction space S7' C3 pieces (ik (N3-1)
is selected (step 59). Below, step 60
．． 61, the curl mark C5 corresponds to the tab designated position.

In this way, by selecting the tTIi auxiliary space character S5 having 1 nit duration (added by q), the auxiliary space S3 is added to the remaining space sl that is smaller than the minimum pitch that can be quickly processed in the output control unit 4o. It is possible to perform high-speed display (printing) in auxiliary space characters smaller than .

In other words, if a character take with a pitch smaller than the minimum pitch (j+17?i 14 'r't) is stored, it cannot be read out at high speed, so it takes time to load it onto the display, and the high-speed display is slow. This is because, while it is not possible to do this, high-speed filling becomes possible by adding the auxiliary space S3 to the remaining space S1, which is less than the minimum pitch, as described above.
