ABSTRACT:
A TV camera is attached to an eyepiece unit of an endoscope and includes a solid-state imaging device. A housing of the TV camera has an outer metallic sheathing. The outer metallic sheathing is hermetically coupled via an insulating material to a metallic housing frame of an electric connector which has contact pins connected to the solid-state imaging device and which is fixed hermetically using a hermetic seal. This structure defines a hermetically enclosed space which can withstand autoclaving. A shielding sheathing layer is formed inside an insulating layer within the hermetic space in order to shield an electric circuit including the solid-state imaging device and which is located inside the shielding sheathing layer. The shielding sheathing layer is designed to communicate with the housing metallic frame of the connector that is isolated and sheathed. This structure provides measures for solving problems concerning electromagnetic compatibility (EMC).
