PURPOSE:To make the construction of the entire part simple and to eliminate the need for taking the operation timing of an energizing lever and a releasing lever by turning both levers with a mirror cam. CONSTITUTION:A frame 132 for holding a mirror and a lever 124 for moving a mirror upward which are pinned 125 to one body are held energized counterclockwise by means of a spring 131 and are prevented from turning counterclockwise by means of a lever 121 for detaining the mirror. The spring 131 is energized by the clockwise turn of a lever 126 for a mirror charging lever 126 and the detention thereof by the lever 121 is released by the counterclockwise turn of an auxiliary lever 96 for the mirror. Since the lever 126 and the lever 96 are both turned by a mirror. Since the lever 126 and the lever 96 are both turned by a mirror cam 16, there is no need for taking the timing of both deliberately and the construction of the entire part is made simple. |
