First Claim
Patent Images
1. A character recognition apparatus for inputting ruled lines which comprises:
- an integrated tablet input device including an input panel and a display panel, the input panel detecting and recognizing information inputted by a stylus pen;
virtual frame setting means for setting a number of virtual frames including grating-like sections within the input panel;
detection means for detecting positional information of the stylus pen indicated on the input panel;
conversion means for converting the positional information of the stylus pen detected by the detection means into a positional information of the virtual frame;
memory means for storing the positional information of the virtual frame;
comparison means for comparing through the positional information of the virtual frames the positions of the stylus pen provided before and after movement thereof on the input panel; and
ruled line input means for inputting a ruled line with a unit length of one frame width and the ruled line being located in at least two virtual frames when the stylus pen is moved therebetween.

Abstract
A character recognition apparatus includes an inputting function of ruled lines. The apparatus is equipped with a tablet type input device integrating a tablet type input device with a display panel. The apparatus includes a control unit that recognizes information inputted in an input panel by a stylus pen. There is a memory unit for storing the recognized information. The control unit sets a grating-like virtual frame in the input panel. The frame set in the input panel is a virtual boarder obtained by calculation and does not appear on a display panel.

7. A recognition apparatus which can accurately input lines inputted by an input device comprising:
-
an input-display tablet for receiving an input; control means operatively connected to the input-display tablet for receiving information from the input-display tablet and outputting information to the input-display tablet, and outputting commands;
fora recognition unit operatively connected to the control means for receiving information from the control means and processing the information to produce a recognized result corresponding to input information and outputting the processed information to the control means; and a ruled line unit that includes a virtual frame unit for receiving commands from the control means for performing a ruled line process to produce a ruled line having a length related to a virtual frame. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. The method of producing ruled lines in a character recognition apparatus with the use of a stylus pen comprising the steps of:
-
(a) inputting rule line information with the stylus pen to an input-display panel; (b) setting in the input-display a plurality of virtual frames which include grating sections; (c) detecting the position of the stylus pen on the input-display panel; (d) converting the position of the stylus pen into positional information on the virtual frames. (e) storing the information produced in step (d); (f) comparing the positional information of the stylus pen on the virtual frames before and after movement of the stylus pen; and (g) producing a ruled line with a unit length of one frame width and is located in at least two virtual frames when the stylus pen is moved between the at least two virtual frames.
