<p><P>PROBLEM TO BE SOLVED: To change the direction of a visual field during photography in a wide range without enlarging an endoscope and to drive an imaging element stably by using a driving substrate. <P>SOLUTION: The endoscope comprises an imaging holder 11 holding an imaging unit 12 including the imaging element 14, a driving substrate 17 for driving the imaging element, driving force transmission mechanisms 21X and 21Y each including a pair of driving rods 22 and 23 having distal ends connected to the imaging holder at diagonal positions, a driving device 51 which makes the driving rods 22 advance or retreat, a support shaft 41 extending from a base member 53 side of the driving device, a relay holder 42 attached to the support shaft for supporting the middle part of the driving rods, and cover members 4, 5 and 6 for covering at least a part of them. By advancing or retreating the driving rods, the imaging unit rotates around two different axes. The driving substrate is arranged between the imaging unit and the relay holder. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
