Abstract
Abstract A recording method and apparatus useful for a photocopy device are disclosed utilizing light energy to move a record forming material onto a record medium. Light energy, particularly from a laser, is focused to minute size and scanned across a member supporting a record forming material. The intensity of the light beam is modulated with information between a level at which said record forming material remains on the support member and a level at which the record forming material is caused to move from the support member to a record medium. A lens mosaic can be used to concentrate the light beam at minute cavities on the support member for containing the record forming material, and this support member can take the form of a screen or a member integral with the lens mosaic having cavities therein. The lens mosaic can be in the form of a semi-cylindrical surface, and a plurality of record forming material support members can be used, each member supporting a material of a different color for producing a color copy.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
205 words
Apparatus for recording information on a record medium comprising: a printing member having a surface including cavities for receiving and containing record forming material, means for depositing a record forming material on said surface of said printing member, means for positioning a record medium adjacent said surface of said printing member, means for generating a light beam, means for directing said light beam to said surface of said printing member including a lens mosaic integral with said printing member and having a multiplicity of lens portions for concentrating said light beam at said surface, said cavities located in said surface of said integral lens mosaic printing member with each of said cavities positioned on the optical axis of one of said lens portions and located at the focus of said one of said lens portions of said lens mosaic, means for scanning said light beam across said lens mosaic to direct said light beam successively through said lens portions, and means for modulating the intensity of said light beam at said surface between a level at which said record forming material remains in the cavities on said surface and a level at which said record forming material is caused to move to the record medium.

Claim 3
Dependent Claim
197 words
Apparatus for recording information from an information bearing sheet onto a record material comprising: means for supporting an information forming material for projection onto a record material and including a surface having cavities therein for containing said information forming material, a lens mosaic integral with said material supporting means and including a multiplicity of lens portions each having its optical axis passing through one of said cavities and each for concentrating a light beam at a cavity portion of said material supporting means, means for positioning a recording medium adjacent said material supporting means, means for generating a coherent beam of light, means for causing said beam of light to sweep back and forth across said lens mosaic for successively focusing said light beam through the different lens portions of said lens mosaic to the cavity portions of said material supporting means, means for modulating the intensity of said light beam at said material supporting means in accordance with information on said information bearing sheet between a level at which said information forming material remains on said material supporting means and a level at which said information forming material is caused to move to the record material.
