Raster output scanner having a full width electro-mechanical modulator
First Claim
1. An image output scanner comprising in combination:
- (a) a source of high intensity radiation;
(b) means for converting radiation from said radiation source to a plurality of individual radiation beams;
(c) an array of flexible reflectors, the number of said reflectors being at least equal to the number of said radiation beams,said reflector array being disposed in the path of said radiation beams so that individual ones of said radiation beams impinge against individual ones of said reflectors whereby said reflectors individually reflect said radiation beams along a first path when said reflectors are undeflected and along a second path when said reflectors are deflected;
(d) an imaging member on which images are created through selective exposure by said radiation beams;
(e) a lens array for transmitting individual radiation beams reflected by said reflectors along one of said first and second paths to said imaging member to expose said imaging member and create images thereon; and
(f) means to deflect said reflectors individually in response to an image signal input whereby to selectively impinge said radiation beams against said imaging member to expose said imaging member and create images represented by said image signals on said imaging member.

Abstract
An output scanner for producing images in response to image signals, the scanner having a high intensity illumination lamp, fiber optic bundle for converting the light output of the lamp to a succession of light rays for exposing an imaging member line by line, an electro-mechanical modulator for modulating the light rays individually in response to image signals, and a lens array for transmitting light rays from the modulator to the imaging member. The modulator comprises a full width array of closely spaced finger-like reflectors which deflect upon application of a preset potential thereto, the potential being applied to the reflectors selectively in accordance with an image signal.

8. An image output scanner comprising in combination:
-
(a) a source of high intensity light; (b) means for converting said light to a linear array of individual light beams; (c) a plurality of flexible reflectors arranged to form a linear array, the number of said reflectors being at least equal to the number of said light beams, said reflector array being disposed in the path of said light beams so that individual ones of said light beams impinge against individual ones of said reflectors whereby said reflectors individually reflect said light beams along a first path when said reflectors are undeflected and along a second path when said reflectors are deflected; (d) a movable imaging member on which images are created through selective exposure by said light beams; (e) a linear array of lens elements for transmitting individual light beams reflected by said reflectors along one of said first and second paths to said imaging member to expose said imaging member line by line and create images thereon; and (f) means to deflect said reflectors individually in response to image signals whereby to selectively impinge individual ones of said linear array of light beams against said imaging member in accordance with said image signals whereby to expose said imaging member and create images represented by said image signals on said imaging member. - View Dependent Claims (9, 10, 11, 12)
