Claims
- 1. In apparatus having (1) a photosensitive surface, (2) a print head having a linear array of light sources, and (3) a gradient index optical fiber imaging lens array with plural optical fibers having substantially the same total conjugate but which lens array is selectable from a group of lens arrays whose total conjugates vary from lens array to lens array within the group; the improvement comprising:
- locating means for removably supporting the print head relative to the photosensitve surface such that the light source array is spaced from the photosensitive surface by the total conjugate of the selected lens array, said locating means including
- A. means defining locating structure of predetermined fixed spacial relationship to the photosensitive surface, and
- B. means defining reference surfaces adjustably attached to the print head and cooperatively engageable with said locating structure to support the print head relative to the photosensitive surface,
- wherein the reference surfaces and the locating structure comprise pins and apertures of substantially larger size than said pins to freely receive said pins, said pins automatically resting against locatings surfaces of said apertures upon mounting of said print head to provide the support for said print head and to accurately locate said print head relative to said photosensitive surface; and
- mounting means for fixatively supporting the imaging lens array to the print head such that the lens array is centered between the light source array and the photosensitive surface.
- 2. The improvement as defined in claim 1 wherein said reference surfaces defining means are fixed on brackets, the brackets being adjustably positioned on the print head.
