<p>PURPOSE:To simultaneously perform the inputs of characters and graphics in a computer, leaving handwritings on paper by using a handwriting writing means such as normal pen and pencil by a user by making a device have a constitution that the surrounding of the tip of a pen is always continued to be monitored, uniting the device with a writing tool in a body, and each operation while a character is written is decided. CONSTITUTION:When a user writes characters on paper, etc., the device body 1 coupled with an arbitrary pencil, etc., operates together with the pencil. By the operation, the acceleration signals Sx and Sy of an X-axis and a Y-axis are detected by X-axis and Y-axis acceleration sensors 12 and 13. When a double integration is performed for the signals in a signal double integration part 15 after the signals are amplified in an amplification part 14, the locus of a handwriting is restored and the written character is recognized in a character recognition part 16. The recognized character is transmitted from a signal transmission part 17 to the outside by radio and infrared ray, etc., by a character code and an existing computer provided with a reception part receives the transmission. The down and up, etc., of the pencil on paper which is required for the double integration of the signal double integration part 15, the decision processings of various kinds of operations and the processing of timing, etc., are performed in a central processing part 19.</p> |
