Abstract
A handwriting detecting and storing apparatus comprises a lens having a cone shape at front-most position of a lens system which introduces handwriting image to image pick up means such as a charge coupled device or the like, and a pen shaft provided at a center of the lens having a cone shape, and wherein an optical axis of the lens system, an optical axis of the lens having a cone shape and a central axis of the pen shaft are coincident with one another, so that a writing operation is performed using a writing device, handwriting image is picked up and picked up handwriting information is stored therein. The apparatus decreases handwriting image which is hidden by an edge section of the writing device as little as possible, and obtains handwriting information within a region of a recording face accurately and with a low cost, the region corresponding to a position just below the leading edge of the writing device and a neighboring region with respect to the position.
