Abstract: A handwriting storing and reproducing method which takes small images including a leading edge for writing and stores the small images in a time sequential manner following a movement of a writing device. The method then reads out the stored small images and overlaps a just read out small image to a previously read out small image so as to obatain a partial image when both small images include portions which include partial handwritings coincident to one another. Thereafter, the method overlaps one partial image to another partial image-so as to obtain a larger image when both partial images include portions which include partial handwritings coincident to one another.

Abstract: A writing device for storing handwriting picks up a handwriting which is written on a paper using a lead, using a CCD area sensor by a predetermined sampling frequency, then stores the picked up image data by the storing device under the control of a microcomputer, so that data storing which data are effective for reproducing the handwriting using a comparatively simple program, is achieved.

Abstract: When characters and the like are written with a writing device, handwriting is detected by a handwriting detection circuit based on outputs from optical sensors and stress sensors and is stored in a handwriting memory section. The handwriting memory section stores the handwriting whereby it can be used as input data for a computer and the like without reductions in the convenience in using the writing device.
