Abstract
A mounting and positioning structure for photoelectric detector units used to generate pulses in response to rotational movement of an automatically focused camera lens. The detector is provided with an integral hollow housing supporting a photocell and a light source on an axis displaced from and parallel to the pivotal mounting axis of the detector. The housing is insertable directly under a cantilevered resilient latch member having a blade-like edge engageable with embossed serrations which radiate from the pivotal mounting axis along one surface of the detector housing. The latch retains the detector in the position so that the light path between the light source and the photocell may be calibrated precisely with a reference determinative of lens focusing position.
