Patent ID: 7550685

Claim:
A compound operation input device comprising: a first operating body, pressably operable in a direction substantially orthogonal to a circuit board, and having a first face exposed for operation and a second face opposite from the first face; a second operating body of annular shape, disposed around the first operating body and substantially parallel to the circuit board, tilt operable in any radial direction from the parallel state, and rotatably operable in a circumferential direction; a first switch actuable in response to pressing movement of the first operating body; a plurality of second switches independently actuable in response to tilt movement of the second operating body; a rotation detector for detecting rotation of the second operating body; and an attachment including: an outer portion, the second operating body being provided with the outer portion, and an inner portion facing the second face of the first operating body, wherein the plurality of second switches are disposed in an outer area on the circuit board outside an area on the circuit board facing the first operating body, and the rotation detector is attached to the inner portion of the attachment and disposed in a space between the circuit board and the first operating body and inside the plurality of second switches.
