Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 134 words
A character and figure processing apparatus comprising: coordinates input tablet having a handwriting input area for receiving handwritten character input; display means including a display area corresponding to said handwriting input area of said coordinates input tablet; designating means for designating the coordinates on said coordinates input tablet, including the handwritten character input; recognizing means for recognizing a character input to said area; display control means for dividing the display area of said display means and displaying a proposed character with regard to the recognized character in the divided display areas of said display means; and selecting means for selecting when one of the divided display areas displaying the proposed character is designated by said designating means, the character displayed in the one divided area as the character input to said handwriting input area.
Claim 2
Dependent Claim 134 words
A character and figure processing apparatus comprising: coordinates input tablet having a handwriting input area for receiving handwritten character input; display means including a display area corresponding to said handwriting input area of said coordinates input tablet; designating means for designating the coordinates on said coordinates input tablet, including the handwritten character input; recognizing means for recognizing a character input to said area; display control means for dividing the display area of said display means and displaying a proposed character with regard to the recognized character in the divided display areas of said display means; and selecting means for selecting when one of the divided display areas displaying the proposed character is designated by said designating means, the character displayed in the one divided area as the character input to said handwriting input area.
Claim 3
Dependent Claim 45 words
A character and figure processing apparatus according to claim 1, wherein said designating means is in the form of a pen, and said coordinates input tablet detects the contact position of the tip of said pen as a coordinates input by an electromagnetic induction system.
Claim 4
Dependent Claim 40 words
A character and figure processing apparatus according to claim 1, wherein said coordinates input tablet is a transparent member in at least said handwriting input area, and the display area of said display means is disposed under said transparent member.
Claim 5
Dependent Claim 182 words
A character and figure processing apparatus comprising: a coordinates input tablet having a plurality of handwriting input areas for receiving handwritten character inputs; display means including display areas corresponding to said plurality of handwriting input areas of said coordinate input tablet; designating means for designating the coordinates on said coordinates input tablet, including the handwritten character inputs; recognizing means for recognizing the characters input to said handwriting input areas; display control means for dividing said corresponding display areas in response to said designating means to designate the display of the proposed characters and for displaying a first proposed character with regard to the recognized characters in one of said divided display areas, and displaying other proposed characters in said concerned divided display areas in conformity with the designation of said display area in which the display is being effected by said designating means; and selecting means for selecting, when one of said divided display areas displaying the proposed character is designated by said designating means, the characters displayed in said divided display areas as the chracters input to said handwriting input areas.
Claim 6
Dependent Claim 182 words
A character and figure processing apparatus comprising: a coordinates input tablet having a plurality of handwriting input areas for receiving handwritten character inputs; display means including display areas corresponding to said plurality of handwriting input areas of said coordinate input tablet; designating means for designating the coordinates on said coordinates input tablet, including the handwritten character inputs; recognizing means for recognizing the characters input to said handwriting input areas; display control means for dividing said corresponding display areas in response to said designating means to designate the display of the proposed characters and for displaying a first proposed character with regard to the recognized characters in one of said divided display areas, and displaying other proposed characters in said concerned divided display areas in conformity with the designation of said display area in which the display is being effected by said designating means; and selecting means for selecting, when one of said divided display areas displaying the proposed character is designated by said designating means, the characters displayed in said divided display areas as the chracters input to said handwriting input areas.
Claim 7
Dependent Claim 45 words
A character and figure processing apparatus according to claim 4, wherein said designating means is in the form of a pen, and said coordinates input tablet detects the contact position of the tip of said pen as a coordinates input by an electromagnetic induction system.
