  • Publication number: 20040078989
    Abstract: An alignment device provides one or more references, such as laser lines and planes in horizontal and vertical orientations. One version of the alignment device includes an optics mounting assembly situated in a pivot socket on a frame to provide an output beam. A spring system and one or more alignment assemblies align and secure the optics mounting assembly in the socket. As a result, the output beam has a desired orientation with respect to true level. The spring system holds the optics mounting assembly in communication with the alignment assemblies to reduce system backlash. One implementation of the pivot socket has a surface in the form of a sphere's interior surface. A set of support members on the optics mounting assembly rest on the pivot socket's spherical surface—causing the output reference beam to extend from the center of a sphere including the socket's spherical surface.

  • Patent number: 6404993
    Abstract: An APS camera having various mechanical features that simplify film pre-loading, especially in single use APS cameras, is disclosed. The disclosed camera employs the film advance mechanism to open and close the APS film cassette's light lock door, and also employs a film sensor to disable the film advance mechanism from operating the light lock door when film is present in a film path of the camera. Camera size is kept to a minimum by a feature that defines a battery compartment within a film spool of the camera.

  • Patent number: 6081666
    Abstract: A method of pre-loading a camera with film and a battery, and specifically a single use camera, is disclosed. According to the disclosed method, the camera is pre-loaded by withdrawing film from a film cassette into a film spool compartment. The battery is then inserted inside the film spool compartment such that the film surrounds the battery.

  • Patent number: 5862414
    Abstract: A method of pre-loading a camera with film, and specifically a single use camera, is disclosed. According to the disclosed method, the camera is pre-loaded in non-darkroom conditions with the back cover assembled to the camera without exposing any substantial portion of the film to any substantial amounts of light. According to the disclosed embodiment, the camera has a film advance mechanism that employs a manual advance wheel, and the manual advance wheel is rotated in opposing directions to pre-load film from a film cassette in the camera to a film spool compartment and to wind film back into the film cassette from the film spool compartment as exposures are taken. In the disclosed embodiment, the camera is an APS camera, and rotation of the manual advance wheel also opens and closes the APS film cassette's light lock door. In a final assembly step and if the camera employs a battery, the battery is inserted inside the film spool compartment.

  • Patent number: 5832311
    Abstract: A single use camera has a film cassette and film spool compartment for receiving unexposed film withdrawn from the cassette. A battery is disposed inside the film spool compartment and is insertable and removable via a port on the bottom of the camera aligned with the film spool compartment. Packaging is disposed about an exterior surface of the camera and is arranged so as to permit an end user to take exposures without removing the packaging but such that removal of at least one of the back cover or battery requires at least partial removal or at least partial destruction of at least part of the packaging.

  • Patent number: 5689733
    Abstract: A method of loading film into a camera that employs a film cassette with a light lock door and has a back cover securely affixed to a main body includes loading the film cassette into a film cassette compartment via a film loading port with the light lock door closed, operating an advancing means to engage a light lock door driver affixed to the camera, rotating the advancing means to open the light lock door with the light lock door driver, preventing further rotation of the advancing means from operating the light lock door driver; continuing to rotate the advancing means to drive film out of the cassette across the film path and into a film receiving slot contained in a film spool and winding film from the cassette onto the spool. Additionally, a camera includes a mechanism for opening and closing a light lock door of a film safe cassette and the mechanism for opening and closing the light lock door.
