  • a housing having a roof mirror array, a lens array, an optical-path separator, a pair of slits extending in the same direction as a longitudinal direction of a lens array, and a mirror member being retained in said housing;

    said roof mirror array composed of an array of roof mirrors arranged at a constant pitch;

    said lens array extending in said longitudinal direction comprosed of an array of lenses at the same pitch as said constant pitch, each of said lenses being optically associated with one of said roof mirrors; and

    each optical axis of said lenses is perpendicular to a recording medium surface;

    said optical-path separator disposed between said roof mirror array and said lens array for separating optical paths between said roof mirrors and said lenses associated therewith;

    said mirror member comprising an elongated transparent plate with a mirror surface formed by vapor deposition on one longitudinal side of the plate which is disposed opposite to and remotely from said roof mirror array with said lens array interposed therebetween, said mirror member extending in the same direction as said longitudinal direction of said lens array, and disposed in covering relation to an exit from said housing;

    a self-scanned recording element fixedly mounted on said housing and having a light-signal producing surface being held in registration with an object surface on which a unit magnification object image would be formed on said recording medium by said lens array and said roof mirror array.
