<P>PROBLEM TO BE SOLVED: To provide an oscillatory operation type input device that enhances detection precision with ease, and easily secures large mechanical strength of a rotative support structure of an operation knob enough to withstand large operational force. <P>SOLUTION: Shafts 15 are fit in fitting holes 3a of both side wall parts 3e of a knob fitting member 3 in a rotation stop state, and each shaft 15 is pivotally supported by a bearing wall part 1a. The operation knob 2 is provided outside the knob fitting member 3, and the operation knob 2 and knob fitting member 3 are united by fastening a fixing screw 16 to the shaft, the both 2, 3 are supported rotatively by the bearing wall part 1a. In a region crossing the rotational center line L of the operation knob 2, a magnet 4 and a magnetic sensor 5 of a detection unit 7 closely face each other, and when the operation knob 2 is operated and rotated, a drive part 3b of the knob fitting member 3 drives the magnet 4, so that the magnetic sensor 5 can detects magnetic field change thereof. <P>COPYRIGHT: (C)2012,JPO&INPIT |
