Abstract
A light-weight print head having an array of LED light emitting elements positioned adjacent an apertured mask is employed to photographically record at very high speeds characters having high resolution so that they are suitable for phototypesetting. The light transmitting apertures have a cross-sectional area substantially smaller than the cross-sectional area of the LEDs and since the apertures may be very accurately positioned with respect to each other, high character resolutions are obtainable despite misalignment between the mask and the array of LEDs. A flat, lightweight, flexible ribbon of conductors is coupled between the moving scanning head and a stationary source of electrical signals. An electrically insulating, opaque filler may advantageously be employed between the LEDs.
