<p>PURPOSE:To omit a flat table which moves a coordinate input means, etc. set at the places near a computer main body and a keyboard, by giving a two-dimensional shift to an indication lever via a rotary member to detect the rotational angle of the rotary member and the shift value of the indication lever in its radius direction. CONSTITUTION:A fixed member 1 is fixed at the side of a supporter and a rotary member 2 is set rotatably to the member 1. A means is provided between both members 1 and 2 to detect the rotational angle of the member 2. Then the coordinate position is indicated and moved two-dimensionally within a range having a radius equal to a slide groove 4 of an arm part 3 by operating manually the knob 6 of an indication lever 5. Thus the operation and shift information on the coordinates are displayed on a display CRT with input of the rotational frequency of the member 2 and the shift value of the lever 5 given to a computer 8. In such a way, a free two-dimensional input is secured for the coordinate position.</p> |
