Abstract

Abstract A character recognizing system determines a character in a character writing frame on a card. The frame defines a character writing region having at least one character writing guide point therein and is divided into a plurality of regions utilizing the character writing guide point as a reference point. A character determining circuit in operative proximity with the card determines the character. The character determining circuit comprising a feature determining circuit for determining the features of the character in the regions into which the character writing region is divided. A feature discriminating circuit is connected to the feature determining circuit for determining the character from the features determined by the feature determining circuit.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 391 words
A character identification system, comprising read-out means which, from a slip having thereon at least one position mark, a character entry frame placed in a specific position relative to the position mark and at least one character entry guide point positioned within the character entry frame, reads out the position mark and characters within the character entry frame by raster scanning means; position mark detecting means for detecting the position mark prepared for determining the character entry position by using a signal obtained by the readout means; horizontal position indicating means for indicating a character entry area in the direction of transfer of the slip, said slip having therein a character entry frame which shows the character entry area maintained in a specific positional relation with the position mark detected by the position mark detecting means and a position on a horizontal axis selecting a corner of the character entry range as an original point; vertical position indicating means for indicating the character entry range in the vertical direction of The character entry area determined by the direction of transfer of the slip or the position on the vertical axis selecting the corner in the character entry area as an original point; character detecting means for detecting a character crossing a position on a coordinate by detecting the coordinate position being scanned by the raster scanning means by means of the horizontal and vertical position indicating means and by detecting the presence or absence of a signal; a plurality of crossing detecting means, storage means connected to said crossing detecting means, said storage means storing the detection result of the character detecting means in said crossing detecting means obtained by detecting the character passing at least one coordinate position of a plurality of coordinate positions predetermined in the form of a plurality of radial lines between the coordinate position used as the character entry guide point within the character entry frame and each coordinate position forming the character entry frame; character extracting means for extracting the feature of a character within the character entry frame in accordance with the crossing conditions obtained by a plurality of the crossing detecting means of the storage means; and identifying means for identifying the character entered in the character entry area in accordance with the feature of the character provided by the character extracting means.
