<p>PURPOSE:To perform the input operation with a single hand in a narrow operation range to improve the operability, by depressing a switch provided on an input pen to set the information code to a desired type and depressing a tablet panel surface. CONSTITUTION:A switch 303 provided on an input pen 202 is depressed to drive a code generating circuit 302, and a desired information code is set to a display part 304. Next, a desired position of a tablet surface 201 is depressed with the input pen 202 to obtain a set timing signal ST from a pen switch 301. The signal ST is inputted to a position information buffer 311, and X and Y information at a depression point F on the tablet panel surface 201 are inputted to the buffer 311 also. Meanwhile, a desired code is held in an information code buffer 312. X and Y information and the information code are set together with the ST signal to a transmitting circuit 313 and are transmitted to a central processing device 102. Thus, the operativity of the operator is improved because it is sufficient if only the tablet panel surface is operated with this single hand.</p> |
