Abstract:
1. An imaging apparatus mountable on an optical instrument, comprising: an imaging device to image an optical image; a two-dimensional drive mechanism including a base member and driving sections that are operable to cause two-dimensional displacement of the imaging device; a cooling device mounted on the base member and configured to cool the imaging device; a thermo-conductive member located between the imaging device and the cooling device; a sealing structure, which air-tightly seals a space around at least the imaging device and the two-dimensional drive mechanism, and which includes an exterior member, an optical member, an elastic member, and a circuit board; and a flexible cable which is provided inside the sealing structure and which couples the imaging device to the circuit board; wherein the circuit board does not have any holes extending therethrough at least in an area thereof corresponding to the sealing structure; and wherein the imaging device operates in synchronism with the two-dimensional displacement caused by the drive mechanism; and wherein the elastic member comprises a ring-shaped member which is more elastically deformable than the circuit board and which is provided between the exterior member and the area of the circuit board without holes.
