Abstract: An imaging device includes an imaging terminal device having an imaging member, a controller having an operation section that operates the imaging terminal device, and a coupling portion that couples the imaging terminal device and the controller to each other in a manner in which the imaging terminal device and the controller can be detached from each other and rotated relative to each other. In the imaging device, the coupling portion is configured by an imaging-side coupling member provided in the imaging terminal device and a controller-side coupling member provided in the controller, the controller-side coupling member being fitted into the imaging-side coupling member, and at least one of the imaging-side coupling member and the controller-side coupling member is provided at a plurality of places.
