PURPOSE:To perform efficient operation by indicating a pattern code by the output signal of a microphone stuck in one body to a cursor for permitting an electronic computer to read the coordinate values of a position of an original drawing mounted on a table. CONSTITUTION:A microphone 1 is stuck to a cursor 3 in one body to constitute a cursor part. The cursor 3 is equipped with a window part having cross hairs for positioning, and an unshown coordinate value reading circuit or transmitter for position display. The output signal of the microphone 1 is analyzed by a voice analyzer 2 and converted into a pattern code. A voice signal may be discriminated by a circle (a), a segment (b) or the starting point of a segment or round, start, etc. A computer 4 performs adequate processing by position coordinate information from the cursor 3 and the pattern code from said voice analyzer 2. Thus, operation is enabled only at hand and any error due to a shift of the cursor during the operation is not generated. |
