摘要

Control device of the diaphragm to apparatus for taking photographic views. / p & & p & the control device of a diaphragm according to the present invention comprises a take-up section of the application for producing an opening information corresponding to the diaphragm brightness of a subject, a stepper motor 54 not turn is not in response to said information, and a coupling ring 48 for activating a connecting pin 50 of the diaphragm in conformity with the raising of a mirror 22 thanks to which the opening of the diaphragm is controlled by the engagement between the locking lever 58 fixed to the shaft of the stepper motor 54 and a section notched 52 formed in the coupling ring 48. The angle of rotation of the stepper motor 54 is n4 of manner a through which extends the position of one of its initial position of the opening of the diaphragm of the stepper motor 54, and another position.
