PURPOSE:To improve S/N by switching a solid-state image pickup element and a focus detecting element, which detects the in-focus state of an object image on said element, in a set position to make the sufficient quantity of light incident on the solid-image pickup element at the time of photographing. CONSTITUTION:A printed circuit board 9 having a CCD8 and a printed circuit board 11 having a focus detecting element 10 are placed and fixed on plane parts 7a and 7b of a rotating plate 7 respectively. An optical path dividing prism 19 is fixed to the element 10 to form the optical path to a light receiving face 10a of the element 10 which coincides with an optical axis 6 and the optical path to a finder part A. When an image pickup start button is depressed, the element 10 receives the object light to detect the focus, and a focusing lens is moved to the focus position by the output. Power is supplied to a rotary solenoid 14 by a completion of this operation, and an arm 15 is turned counterclockwise at 90 deg.. Thus, the plane part 7a (or 7b) is set to the vertical (or horizontal) state as shown in a figure (b), and the CCD8 goes onto the optical axis instead of the element 10 and the prism 9, and the element 10 and the prism 19 are drawn back from then optical axis 6. |
