PURPOSE:To perform remote controlling easily with simple constitution by performing the movement of a photodetecting surface by a linear moving mechanism operated by a turning of a motor. CONSTITUTION:The target surface 141 of an image pickup element 14 is disposed on the optical axis 12 of a lens system 10, and a yoke assembly 16 is provided on the outside circumference of the element 14. At both front and rear ends of this assembly 16, two guide bars 22, 24 are inserted into the through-holes 181, 182 and 201, 202 of sliding support bodies 18, 20. A reversibly running motor 32 moves the element 14 in remote and near directions with respect to the lens system 10 by means of a worm of a worm 26 and a feed screw part 183 via gears 30, 28, thereby performing remote focus controlling. |
