Abstract
A recording apparatus includes a plurality of Xenon flash tubes and a separate enclosure for each of said flash tubes. Each enclosure is provided with a slit through which light from the associated flash tube emerges to form a relatively small line segment. The slits are all located in a recording plane and may be disposed in an H-shaped or C-shaped recording array, as desired. When placed in cooperative relation with a moving light sensitive recording medium that is ultrasensitive to a predominant wavelength of the light produced by said flash tubes, selective and appropriate flashing of said flash tubes produces dense analog time code and other traces on said recording medium.
Claims6
A light box matrix having a plurality of interior compartments and an exterior face in which a plurality of slits are arranged in a recording array, a plurality of flash tubes, means for mounting one of said flash tubes in individual ones of said compartments, an opaque member mounted in another of said compartments, said opaque member being configured to provide light tight isolation of said flash tubes from each other, said opaque member having a cylindrical opening therein to direct light from one of said flash tubes to pass to and through a first one of said slits, said opaque member having a first reflecting surface disposed at a first angle with respect to said cylindrical opening to reflect light from a second one of said flash tubes to and through a second one of said slits, said opaque member having a second reflecting surface disposed at a different angle with respect to said cylindrical opening to reflect light from a third one of said flash tubes to and through a third one of said slits.
A light box matrix having a plurality of hollowed out interior spaces and an exterior face in which a plurality of slits are arranged in a recording array, a plurality of flash tubes, certain of said interior spaces each having means therein for mounting one of said flash tubes therein, a member positioned in said another one of said interior spaces and arranged to provide light tight isolation of said flash tubes from each other, said member having an opening therein to direct light from one of the flash tubes to and through an individually associated one only of the slits of said recording array, said member having a first reflecting surface to reflect light from another one of the flash tubes to and through a second and individually associated one of said slits, and said member having a second reflecting surface to reflect light from a third one of the flash tubes to and through a third and individually associated one of said slits.
