Is a state in which the diaphragm aperture by the blades 22 and 23 has a maximum value. That is, by operating the aperture lever 15 to the right in the drawing while holding the lock knob 18, the drive pin 17A moves the blade 22 upward and the other drive pin 17
B moves the blades 23 to the lower side, and both openings 22A,
23A coincides with each other, and the aperture opening 101 becomes maximum.

なる。From this state, when the aperture lever 15 is oscillated to the left side of the drawing, the blade 22 is moved downward by the drive pin 17A and the other drive pin 1 is moved as shown in FIG. 7 (A).
7B moves the blade 23 upward, and the blades 22, 2
Numeral 3 is restricted by a restriction pin 21 so as to move vertically accurately in a straight line. Therefore, the openings 22A of both blades 22 and 23,
The overlapping area of 23A becomes small, and the diaphragm aperture is narrowed down as shown in FIG. When the aperture lever 15 is operated to the leftmost end, the blade 22 moves to the lowermost end, and the opening 22A is blocked by the blade 23,
The blade 23 moves to the uppermost end, and the opening 23A is moved to the blade 2
It is blocked by 2, and the diaphragm aperture is in the closed state (0).
