Inkless printer

摘要

An inkless printing device that comprises a plurality of lasers, a rotating polygonal mirror, and an energy recycling unit. The mirror rotates and reflects a laser beam in a manner that allows the beams to reach any point on the paper. The laser turns ON and OFF while the mirrors are rotating to form a printout. Printing on a sheet of paper is achieved by burning to a certain pre-determined depth of the paper, by using the thermal properties of a laser. The energy recycling unit converts the heat energy generated during the printing process to electrical energy and charges a battery cell. Upon the battery cells being charged to a pre-determined power threshold, the power supply to the printer is changed from the AC supply to the battery supply.

主权项

1. An inkless printer comprising:
a stationary laser configured to emit a beam of a desired power intensity; a polygonal shaped rotating mirror configured to direct the beam to a paper; a lens configured to focus the laser beam to a point on the paper and print data on the paper by burning the paper; an energy recycling component that includes a plurality of thermoelectric cells and is configured to convert heat energy generated by burning the paper to electric energy used to charge a battery; an AC power supply configured to power the inkless printer; a LED display configured to display the inkless printer settings and a battery charge level; and a controller configured to switch the power supply to the inkless printer from AC power supply to a battery upon detecting that the battery charge level is equal to a predetermined threshold.
