Abstract: A camera having a camera finder system including a finder housing having a camera finder. The camera further includes a movable housing linearly movable into the finder housing whereby the camera finder is moved forward out of a camera body or backward into the finder housing of the camera; and drive device for linearly moving the movable housing.

Abstract: A rigid camera with a film holder independently rotatable about a horizontal axis and a vertical axis. The film holder rotates synchronously with the focusing plate of the viewfinder. The focusing plate rotates independently about a first horizontal axis parallel to the horizontal axis of the film holder when the film holder rotates about its horizontal axis, and about a second horizontal axis perpendicular to its first axis when the film plane rotates about its vertical axis.

Abstract: An inverted Galilean finder incorporated in an automatic focusing camera has an optical system including an objective lens, an eyepiece and a transparent cover plate disposed in front of the objective lens for protecting the finder optical system from foreign particles. The cover plate is formed on its front surface with a framing marking for defining an exposure frame and a target marking which is directed toward an object to be focused when taking a picture and on its back surface with diopter adjustment lenses arranged correspondingly in position to the framing and target markings, respectively.

Abstract: Apparatus in a photographic camera for moving an exposed section of a filmstrip loaded into a camera from the exposure gate to a curl-developing area located along the film transport path after a predetermined period of camera inactivity as measured by an included timing circuit so as to prevent the onset of a reverse curl. According to the invention, the apparatus includes a control mechanism for automatically advancing a succeeding unexposed film portion to the exposure gate upon reactivation of the camera.

Abstract: A camera includes a lens barrel which can be retracted into a camera body, and a lens barrel storage control apparatus. The lens barrel has a front lens group mounted in a front end portion thereof and a rear lens group movably disposed therein. The lens barrel storage control apparatus, first, controls a stepping motor for driving the rear lens group to locate the rear lens group at a standby position in the barrel, and then controls a DC motor for driving the lens barrel to retract the lens barrel into the camera body while keeping the rear lens group at the standby position. Also, when it is detected that the rear lens group is not located at the standby position, the control apparatus controls the DC motor to locate the lens barrel at a suitable position within a range where the lens barrel can be set in a photographable state.

Abstract: A camera includes a photographic information output circuit section, a CPU, a PPM signal conversion circuit section, a drive section for a plurality of magnetic heads, and a film feeding section. The CPU converts several parallel data items which are output from the photographic information output circuit section into a single serial data item and outputs it to the PPM signal conversion circuit section, which then converts this single serial data item thus output from the CPU into several PPM signals, and then the PPM signal conversion circuit section supplies the PPM signals to the magnetic head drive section.

Abstract: A single-lens reflex type camera which is very more compact than the conventional single-lens reflex camera, or is equal to the COMPACT camera in compactness. Two prisms 4 and 5, between which a slantingly extending low refractive index layer 15 is sandwiched, are positioned between the photographing lens 3 and the photosensitive surface 9. A Fresnel mirror 6 with a reflecting and/or deflecting function is arranged between the prism 5 and the photosensitive surface 9.

Abstract: A camera having a zoom system which comprises a front lens group driven by a DC motor and a rear lens group driven by a stepping motor includes a motor control apparatus for controlling the DC motor and the stepping motor. The motor control apparatus voltage measuring means for measuring a voltage of a power source for driving the DC motor and the stepping motor, decision means for deciding as to whether the voltage is more than a predetermined value, means for simultaneously driving the DC motor and the stepping motor, if a decision is made that the voltage is more than the predetermined value, and means for driving only the DC motor and thereafter driving only the stepping motor, if the voltage is not more than the predetermined value.
