PROBLEM TO BE SOLVED: To provide a compact focus controller that is fixed to a camera device, builds in a radio communication unit inside an operation part, and allows a stable radio communication without impairing operability.SOLUTION: A controller fixed to a camera device of an imaging device including a lens device and the camera device and performing a radio communication of a signal to a movable optical unit of the lens device is configured to comprise: a fixing part that is fixable to the camera device; operation means that rotates with respect to the fixing part; rotation position detection means that detects a rotation position of the operation means with respect to the fixing part; and radio communication means that performs a radio communication of position information detected by the rotation position detection means with the lens device. The radio communication means does not rely on the rotation position of the operation means, but includes an antenna having directivity in a predetermined direction. |
