Abstract

A nonimpact radiant energy printer is shown. The printer utilizes a source of radiant energy 10 such as a laser which produces a series of bursts of energy. The bursts of energy are synchronized with a rotatable character mask disk 12 and print position emitter 18 so that the selected character is formed by the energy passing through the character mask and impinging on mirror or prism 14 to direct the energy to the print member 20 at the selected print position. Two prisms 14 are provided on an endless belt 16 which is continuously driven by suitable drive means working through pulleys 22. Print member 20 may comprise conventional sheets of multiple copy paper interleaved with carbon paper.

Nonimpact Radiant Energy Printer

A nonimpact radiant energy printer is shown. The printer utilizes a source of radiant energy 10 such as a laser which produces a series of bursts of energy. The bursts of energy are synchronized with a rotatable character mask disk 12 and print position emitter 18 so that the selected character is formed by the energy passing through the character mask and impinging on mirror or prism 14 to direct the energy to the print member 20 at the selected print position. Two prisms 14 are provided on an endless belt 16 which is continuously driven by suitable drive means working through pulleys 22. Print member 20 may comprise conventional sheets of multiple copy paper interleaved with carbon paper. The energy impinges upon and is absorbed by the paper so that energy absorbed in the carbon paper softens the wax vehicle and permits a carbon image of the selected character to transfer to the paper. A line of printing can be accomplished as prism 14 is moving across the line. The carriage is then spaced while the second prism 14 is moved into print position at the start of the next print line. Alternatively, the print member 20 can be continuously driven by tilting belt 16 downward at the right end to the next print line position.
