1. A character recognition apparatus for recognizing entered characters, comprising:
- holding means for holding a dictionary which stores strokes constructing a standard character in accordance with an order in which prescribed points of each stroke of the standard character are projected upon a line;
storage means for storing a plurality of strokes constructing the entered character in accordance with an order in which prescribed points of each stroke of the plurality of strokes are projected upon the line;
matching means for matching strokes constructing the entered character stored in said storage means with strokes constructing the standard character stored in said dictionary in accordance with the order in which the strokes constructing the entered character are stored in said storage means; and
recognition means for recognizing a character, which is constructed by the entered plurality of strokes, based upon results of the matching performed by said matching means.

Abstract
A character recognition apparatus is provided with a recognition dictionary that stores the strokes of standard characters in an order that is in accordance with a predetermined rule for deciding the order of each stroke by the positional relationship of each stroke. A plurality of strokes are stored on a storage medium in an order in accordance with the predetermined rule. The plurality of strokes stored on the storage medium and each stroke of the standard characters stored in the recognition dictionary are compared. The character constructed by the plurality of strokes is recognized based upon the results of comparison.
