PROBLEM TO BE SOLVED: To provide a sterilizable electronic video camera for an endoscope. SOLUTION: The electronic video camera comprises an enclosure, a lens cell, a lens cell holder, an image sensor, a motor-driven focusing system and a switch control part. The enclosure comprises a housing and a cover, and the housing defines a cavity therein. The cover has a window disposed therein, and the housing and cover are adapted for hermetic coupling. The lens cell is slidably disposed in the lens cell holder. The image sensor is in optical communication with the lens cell and window. The motor-driven focusing system is adapted to axially reciprocatingly move the lens cell relative to the lens cell holder controlled by the switch control part. The switch control part is activated from outside the enclosure and is hermetically sealed therewith. The lens cell, lens cell holder, image sensor and the motor-driven focusing system are coupled as an assembly to the cover and disposed within the cavity. COPYRIGHT: (C)2006,JPO&NCIPI
