Abstract
An electrostatic transmission mechanism can be adopted for use in data media recorders such as printers, facsimile machines, or scanners to transport media. The invention has a feed roller with an electrostatic field generator located therein to generate static electricity on the surface of the feed roller to attract and transport media. The invention can eliminate the disadvantages of conventional transmission mechanisms such as crumpled paper resulting from the pressing of the feed rollers, star wheel tracks on the paper caused by the star wheels, etc.
Claims12
An electrostatic transmission mechanism for data media recorders to transport a paper through feeding, printing and discharging operations, comprising:
- a feed roller driven to rotate by a driving apparatus of the data media recorders to transport the paper;
- and
- an electrostatic field generator connecting electrically to the feed roller to generate static electricity on the surface of the roller to attract the paper and to allow the paper to move on the surface of the feed roller in a flat and smooth manner.
An electrostatic transmission mechanism for data media recorders having a feed roller to transport media required by the data media recorders, characterized by:
- two pairs of conductive wires crossing with one another and being laid on the surface of the feed roller and said conductive wires connecting to a power supply to generate static electricity on the feed roller to attract and transport the media.
