<p>PROBLEM TO BE SOLVED: To miniaturize a sensor and to read a drawing showing even the size of a tablet or the documents, etc., by combining optionally a detector using the circular or rotary scan of a sensor, a position detector and a sensor tilt detector respectively. SOLUTION: An input part consists of a tablet part 1, a detector 2 using the rotary scan or a circular sensor 3 and a detection coil 4 which detects the position and tilt of the sensor 3. The relation between the part 1 and the coil 4 of the input part is inputted to a position/tilt detection circuit 5 and an image sensor drive circuit 6. Thus, the angle formed between an original coordinate axis and the scanning direction is corrected by a change amount of the tilt angle caused at the scan starting point of the sensor 3. These corrected outputs 7, 8 and 9 are processed by a computer and outputted to a host computer. As a result, the sensor 3 can be miniaturized and also a drawing showing even the tablet size or the documents, etc., can be easily read.</p> |
