Document display processing apparatus including means for controlling the display of plural text block groups

A document processing apparatus for controlling the display of text on a display frame of a display device, said apparatus comprising:

• coordinate input means for inputting user instructions including display coordinates of the display frame as specified by a user;
• text block group control means for controlling a grouping of text to be displayed on said display frame, said text block group control means including (1) memory means for storing a plurality of text characters, (2) block area coordinates storing means for storing information indicative of coordinates of a plurality of rectangular display areas of the display frame each constituting a text block area, (3) text block specifying means for specifying text characters from among the plurality of text characters, the text characters specified by said text block specifying means for display in each of the plurality of rectangular display areas stored in said block area coordinates storing means, (4) text block display means for controlling the display of the text block areas stored in said block area storing means containing the text characters specified by said text block specifying means, and (5) text block group management means for designating a text block group containing one or more text block areas to be displayed by said text block display means;
• and
• display control means for receiving the user instructions from said coordinate input means and for controlling said text block group control means in accordance with the user instructions, said display control means including (1) specified text block detecting means for detecting which one of a plurality of displayed text block areas has been specified by the user based on the display coordinates of said coordinate input means, (2) specified text block group detecting means for detecting a displayed text block group containing the one of the plurality of displayed text block areas detected by said specified text block detecting means, and (3) stream-in operation means for automatically transferring, responsive to a corresponding user instruction via said coordinate input means, text characters from one text block group detected by said specified text block group detecting means as being superimposed on a displayed figure within the display frame to another defined text block group which is not superimposed on the displayed figure within the display frame;
• wherein said stream-in operation means includes (1) a text block area direct specifying means for automatically specifying a rectangular display area of a new text block area which does not overlap any displayed figure, (2) a replacement text block forming means for forming the new text block area specified by said text block area direct specifying means, (3) a replacement text block character number computing means for computing a number of text characters to be included in the new text block area according to a size of the new text block area, (4) a character integrating means for integrating all of the text characters specified by a corresponding sentence block specifying means so as to write the text characters as one continuous text into said text character storing means, (5) a replacement text block specification setting means for extracting a number of characters computed by said text block character number computing means from among the continuous text so as to set the extracted characters into the text block area newly formed by said replacement text block forming means, and (6) a replacement block group forming means for forming a replacement block group containing at least one newly formed block group area.
