<p><P>PROBLEM TO BE SOLVED: To provide a hard electronic endoscope with excellent operability to change the direction of the visual field by simple operation. <P>SOLUTION: The endoscope has an illumination and imaging unit 22 disposed rotatably around a pin 41 inside the distal end part 21 of a hard insertion part 12, and a plunger 42 disposed on the back side of the unit 22. The plunger 42 has a movable piece which can project. The movable piece is made to project by the switch operation of a scope switch 47 etc., to rotate the illumination and imaging unit 22 around the pin 41, so that the state of illumination and imaging can be easily shifted from the direct viewing to the oblique viewing. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
