Abstract
PURPOSE: To accurately and readily perform mutual position aligning of the two lens-barrels by freely inserting the second lens-barrel to the first lens-barrel and making the other lens-barrel adjustable in the rotating, vertical and lateral directions with respect to one lens-barrel.
CONSTITUTION: In the finder system of a cine camera, the first barrel 11 holds a focus plate 7 and a lens 8 and is fixed to the camera case C by means of screws. The second barrel 14 holds a mask 9 and is freely inserted onto the first barrel 11 movably in the rotating, lateral and vertical directions. An eccentric pin 15 is rotatably supported to the second barrel 14 and its end part 15a is engaged with the oblong hole 22 of the first barrel 11 to adjust the rotation of the second barrel 14. An eccentric pin 16 is rotatably supported to the camera case C and its end part 16a is engaged with the oblong hole 17 of the barrel 14 to adjust the barrel 14 in the vertical direction through its rotation. Also, a small screw 18 is freely inserted into the oblong hole 19 of the case C and is screwed into the threaded hole 20 of the barrel 14 to move and adjust the barrel 14 in the lateral directions. The position in the rotating direction is determined by the abovementioned eccentric pin 15 and the mask 9 and focus plate are adjusted by moving the second barrel 14 vertically and laterally by the eccentric pin 16 and screw 18.
