POSTAGE METER TYPEWHEEL SELECTOR HAVING A WORM GEAR DRIVE AND GUIDING SLEEVE

摘要

This invention relates to a postage meter having a plurality of worm gears for adjusting the rotational position of postage print wheels. Each worm gear selectively moves a rack which is an engagement with a postage print wheel so as to provide rotational movement to the print wheel. Sensors are provided so that the rotational position of each worm gear can be determined thereby indicating the position of the print wheels. A sleeve is located within the housing to provide support to the worm gears and maintain alignment of the racks during printing.
