  • Patent number: 4697897
    Abstract: A watertight camera is disclosed in which the normal line of a transparent protection plate for an objective of the finder, or the normal line of a protector for the strobe, is inclined toward the axial direction of the photographic lens. While there is no interference during in-the-air photography, underwater photography is carried out more advantageously.

  • Patent number: 4668061
    Abstract: A buckle device for a water-proof camera is disclosed, including a buckle arm pivotally mounted at its one end to the camera housing, and a buckle body whose one end is pivotally mounted on the free end of the arm and whose opposite end has a bent-over lug from a pin on the back lid of the camera. The buckle arm has a spring-biased buckle lock member arranged to engage in a recess provided in the camera housing. By slidingly moving the buckle lock member against the bias spring, the buckle arm is released from the connection with the recess. In this releasing position, the buckle lock member then functions as a handle for taking the lug from engagement with the back lid of the camera housing. Therefore, the back lid is surely prevented from opening by accident.

  • Patent number: 4666275
    Abstract: In the disclosed camera, an arrangement shifts the light detecting location of a light sensor facility from a first position offset from the camera's optical axis to a second light detecting location offset from the axis and angularly displaced from the first position. In a specific embodiment, a mount, rotatable about an objective lens, shifts a light detector from below the lens to the side of the lens so that when the camera is turned from a horizontal to a vertical position, the light detector may still be located below the lens. Preferably, the mount also carries the flash emitter of a flash unit and a camera grip so they retain their positions when the camera is turned. Effectively, the light detector, the flash emitter, and the grip remain in position while the camera body is turned.

  • Patent number: 4572640
    Abstract: The present invention relates to a camera having an automatic focusing device, particularly designed so that the shutter release operation is carried out only when the distance measuring operation is carried out properly before taking a photograph in order to avoid an out-of-focus photograph. During flash photography, the aperture value of the camera is controlled in accordance with the object distance value set by means of the automatic focusing device.

  • Patent number: 4482226
    Abstract: A drive gear is arranged to rotate in response to driving torque from an electric motor, and is supported for swinging movement by a shaft the axis of which is different from the axis of rotation of the drive gear. Also, the drive gear is urged by a bias force in a direction for release from meshing engagement with a transmission gear of a film rewinding system. When rewinding of a film is completed, and a load which is exerted on the film rewinding system during rewinding disappears, the meshing force between the drive gear and the transmission gear is reduced. The reduction in the meshing force effects an automatic release of the drive gear from the meshing engagement with the transmission gear.

  • Patent number: 4479705
    Abstract: A spool drive type camera in which the taking up of the film is carried out only by the rotative force of the spool, while the one-frame advancement of the film is controlled by the revolution of the sprocket as it is driven by the film transportation is provided with automatic switching means for selection of a mode in which the above-described one-frame advancement is effected by the rotative force of the winding up system when a film is not loaded in the above-described camera.

  • Patent number: 4417795
    Abstract: In the disclosed automatic focus detection device, two image forming lenses have optical axes fixedly spaced a predetermined distance. Distance measuring elements are arranged near the focal points behind each image forming lens. A holding member holding one of the distance measuring elements is rotated around a shaft outside of the space between the optical axes of the two lenses so as to alter the distance between the distance measuring element and the image forming lens. According to an embodiment, one of the measuring elements is a light source which scans the object through one of the lenses when the holding member is rotated. Rotation of the holding member refocuses the light source throughout its scan.
