Abstract

PURPOSE:To simplify a daylight photographing-flash photographing mode changeover mechanism by the constitution wherein a detecting member displacing according to film sensitivities and object distances is changed over by a changeable aperture value regulating member and is operated cooperatively with a diaphragm blade operating member. CONSTITUTION:When a strobe 26 is contained in the prescribed position of a camera body, the leading end part of a flash mode aperture value regulating member 24 is pressed to a cushion member 27 and therefore the member 24 moves to the position shown by an alternate long and short dash line and the pin 24b of the member 24 also moves to position outside the moving range of a film sensitivity detecting lever 22, by which it is disengaged and a daylight photographing mode state is set. The regulation of a distance detecting lever 20, the lever 22 and the member 24 upon aperture values is perfectly released. If the strobe 26 is moved upward up to the solid line part from such state, the member 24 is released from pressure, and changes over to the state of the flash photographing mode shown by a solid line.
