摘要： The present invention relates to a power source used in a camera having a circuit for detecting a focused condition determining the distance at which the focused condition is established. The invention is particularly suited, for preventing careless opening of the power source by providing an operating member on the lens barrel or a light or temperature sensing element either in the lens barrel or in the view finder respectively. In this manner the power supply switch is functionally engaged in the operating member or operates in response to the output of either the light or temperature sensing element so as to close the current supply circuit.

摘要： In an automatic focusing screen unit transparent photoelectric transducing means at a central portion of the image receiving surface area of a glass plate are capable of generating an output signal commensurate with the sharpness of an image formed thereon by an objective lens of a camera. An electrical circuit for processing the output signal of the transducing means produces an output during sharp focus. In a preferred embodiment, this circuit is constructed in the form of an integrated circuit chip for incorporation in the unit together with indicating means responsive to the output signal of the circuit for indicating a sharp focus condition.
