Abstract

Abstract An internal drum plotter including a laser source (10) producing a laser beam output, apparatus (14) for modulating the laser beam output to apply information content thereto, apparatus (22) for supporting laser recording material in a generally circular cylindrical configuration about a cylinder axis (20) and scanning apparatus (23) for receiving the modulated laser beam and reflecting it onto the laser recording material, the scanning apparatus (23) including a stabilized reflector (26) arranged for rotation about the cylinder axis (20) for reflecting the modulated laser beam directly onto the laser recording material, wherein the stabilized reflector (26) is insensitive to wobble in the position thereof in directions perpendicular to the cylinder axis (20).

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 103 words
An internal drum plotter comprising: a laser source producing a laser beam output; means for modulating the laser beam output to apply information content thereto; means for supporting laser recording material in a generally circular cylindrical configuration about a cylinder axis; and scanning means for receiving the modulated laser beam and reflecting it onto the laser recording material, the scanning apparatus including a stabilized reflector arranged for rotation about the cylinder axis for reflecting the modulated laser beam directly onto the laser recording material, wherein the stabilized reflector is insensitive to wobble in the position thereof in directions perpendicular to the cylinder axis.
Claim 2
Dependent Claim 103 words
An internal drum plotter comprising: a laser source producing a laser beam output; means for modulating the laser beam output to apply information content thereto; means for supporting laser recording material in a generally circular cylindrical configuration about a cylinder axis; and scanning means for receiving the modulated laser beam and reflecting it onto the laser recording material, the scanning apparatus including a stabilized reflector arranged for rotation about the cylinder axis for reflecting the modulated laser beam directly onto the laser recording material, wherein the stabilized reflector is insensitive to wobble in the position thereof in directions perpendicular to the cylinder axis.
Claim 3
Dependent Claim 17 words
An internal drum plotter according to claim 1 and wherein said stabilized reflector comprises a penta prism.
Claim 4
Dependent Claim 34 words
An internal drum plotter according to claim 1 and wherein said stabilized reflector comprises a combination of mirrors which is insensitive to wobble in the position thereof in directions perpendicular to the cylinder axis.
Claim 5
Dependent Claim 46 words
An internal drum plotter according to any of the preceding claims and wherein said means for supporting includes means for securing the recording material against a cylindrical support surface by exerting a compressive force thereon in the plane of the material, tangentially to the cylinder axis.
Claim 6
Dependent Claim 44 words
An internal drum plotter according to any of the preceding claims and also comprising automatic apparatus for feeding and removing the recording material in association with the apparatus for supporting, thereby enabling the internal drum plotter to be operated outside of a darkroom environment.
Claim 7
Dependent Claim 42 words
An internal drum plotter according to any of the preceding claims and also comprising means for displacing the scanning means axially along the cylinder axis and for synchronizing the axial motion of the scanner means with the rotation of the stabilized reflector.
Claim 8
Dependent Claim 40 words
An internal drum plotter according to any of the preceding claims and also comprising means for synchronizing the supply of data to the modulating means with the axial displacement of the scanning means and the rotation of the stabilized reflector.
Claim 9
Dependent Claim 87 words
An internal drum plotter comprising: a laser source producing a laser beam output; means for modulating the laser beam output to apply information content thereto; means for supporting laser recording material in a generally circular cylindrical configuration about a cylinder axis, including means for securing the recording material against a cylindrical support surface by exerting a compressive force thereon in the plane of the material, tangentially to the cylinder axis; and scanning means for receiving the modulated laser beam and reflecting it onto the laser recording material,
Claim 10
Dependent Claim 87 words
An internal drum plotter comprising: a laser source producing a laser beam output; means for modulating the laser beam output to apply information content thereto; means for supporting laser recording material in a generally circular cylindrical configuration about a cylinder axis, including means for securing the recording material against a cylindrical support surface by exerting a compressive force thereon in the plane of the material, tangentially to the cylinder axis; and scanning means for receiving the modulated laser beam and reflecting it onto the laser recording material,
