Abstract
PURPOSE: To make construction compact and cost low by moving a mirror upward as desired and enabling the lens barrel to be housed in an empty space thereby.
CONSTITUTION: The collapsion operation takes place like this. A lens barrel 21 is given left turn by a mirror pressing spring 23 as the contact face 21a makes engaging contact with the projecting part 22c of a mirror coupling ring 22. The meshing of a click stop spring 24 and a click groove 21b is released when the lens barrel 21 is manually turned left. As a result of this left turn, the lens barrel 21 stops in the position where each of projecting parts 21c1, 21c2, 21c3 can go into each of the recesses 27a, 27b, 27c of a body flange 27. Such left turn of the mirror coupling ring 22 causes a mirror arm 22a to press the 1st arm 5a which then turns a mirror lever 5a left, and this causes the lever 5 to turn the mirror 1 left against a mirror spring 3, thereby moving the mirror 1 upward. If the lens barrel 21 is pushed in after this, it is housed in the space after the mirror 1 has ascended, thus assuming a collapsed state.
