Estimating the term…
An optical printing device includes a photosensitive means having a photosensitive surface and an optical print head. The optical print head has a plurality of arrays of a plurality of light emitting devices selectively energized and an optical means to form light images from the light emitting devices on the photosensitive surface. A plurality of the light emitting device arrays are arranged in a plurality of rows, with the light emitting devices aligned in a common direction with the arrays. The optical means comprises a plurality of graded index optical fiber arrays causing light images from the light emitting devices to be formed in a single line on the photosensitive surface.
An optical print head for optical printing devices comprising light emitting device arrays having a plurality of light emitting devices selectively energized and arranged in a row, said light emitting device arrays being arranged in a plurality of rows with said light emitting devices aligned in a common direction with said light emitting device arrays, and a plurality of graded index optical fiber arrays focusing the whole of light images from said light emitting devices so as to be formed in a single image line on a photosensitive surface of photosensitive means, each of said graded index optical fiber arrays being arranged opposite to each corresponding row of said light emitting device arrays and each of said graded index fiber arrays having an equimultiple lens power.
