Abstract
A camera with an internally arranged electronic flash device in which there is arranged a distance control knob releasably interlocking with a power source switch of the flash device. When the object to be photographed needs the flash device under conditions of low luminance the power source switch is moved to a suitable position indicating a particular distance between the object and the camera while the power source switch is moved into the "ON" position. When the photograph is taken with natural light the distance control knob is operated independently of the power source switch.
Claims5
A photographic camera having a built-in electronic flash device and a power source connectable to the flash device, comprising:
- a. a housing having a groove;
- b. a photographic objective lens within said housing, said lens being movable forward and backward along an optical axis of said lens;
- c. first knob means slidably movable along said groove for actuating focus adjusting means for moving said lens along said optical axis;
- d. second knob means slidably movable along said groove between ON and OFF positions, said second knob means when moved to said ON position connecting said power source to said flash device and disconnecting said power source from said flash device when in the OFF position, said second knob means having an arm for slidably moving said first knob means simultaneously with said second knob means when said second knob means is moved along said groove within the ON position range;
- and
- e. means operatively connected to said second knob means for selecting the rate of passage of light to said lens;
- said first knob means sliding within said groove when said second knob means is moved to said ON position thereby actuating said focus adjusting means to provide focal adjustment and said means for selecting the rate of passage of light to said lens simultaneously with connection of said power source to said flash device, said first knob means being slidable solely along said groove when said second knob means is at said OFF position.
