Abstract
Abstract An imaging recorder wherein a linear array of laser diodes (12) is mounted to project the output of the diodes onto a thermally activated photosensitive material (14) movable along a predetermined path. The array of diodes (12) is linearly aligned in a direction parallel to the path of movement of the material and the laser diodes are activated simultaneously as a group. Optical means (25) are provided between the array of laser diodes and the material to provide an imaging spot (26) on the material which is elongated in a direction perpendicular to the path of movement of the material.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
140 words
An imaging recorder device wherein images are produced by the application patterns to an imaging material comprising: means for moving an imaging material along a predetermined path a plurality of light radiating elements in spaced relation with the path of the material and disposed to project their output toward the path of the material; means for applying power simultaneously to said plurality of light radiating elements as a group to heat the thermal imaging material, said light radiating elements being linearly arranged in a direction substantially parallel to the path of movement of the material; and optical means disposed between said light radiating elements and the path of the material for converting the image of said light radiating elements on the material to an irradiated region which is elongated in a direction linearly perpendicular to the movement of the material.
Claim 2
Dependent Claim
140 words
An imaging recorder device wherein images are produced by the application patterns to an imaging material comprising: means for moving an imaging material along a predetermined path a plurality of light radiating elements in spaced relation with the path of the material and disposed to project their output toward the path of the material; means for applying power simultaneously to said plurality of light radiating elements as a group to heat the thermal imaging material, said light radiating elements being linearly arranged in a direction substantially parallel to the path of movement of the material; and optical means disposed between said light radiating elements and the path of the material for converting the image of said light radiating elements on the material to an irradiated region which is elongated in a direction linearly perpendicular to the movement of the material.
