PROBLEM TO BE SOLVED: To execute incorporation in a keyboard naturally and uniquely move a painter in an operation direction by means of a finger tip by providing fixed links whose base end parts are pivotally supported at a fixed shaft, a pointing button and encoders. SOLUTION: A pair of the fixed links 2U and 2D whose base end parts 2a are pivotally supported at the fixed shaft 1 are used, one end parts 4a of the pair of mobile links 4U and 4D indicating a case at the time of the same measure as the fixed links 2U and 2D are respectively pivotally supported in the joint pins 3 of the tip parts 2b and the pointing button 6 which can be operated in the desired direction P by the finger tip is fixed at the common mobile shaft 5 of the other end parts 4b. Segment teeth 7 are respectively formed on the peripheral surfaces of the base end parts 2a of the respective fixed links 2U and 2D, the pinion gears 10 of the pair of encoders 9U and 9D which are pivotally supported in a substrate 8 are respectively engaged with the respective segment teeth 7 and the rotary direction and rotary quantity of the fixed links 2U and 2D with the fixed shaft 1 as a center are detected by the respective encoders 9U and 9D. |
