Abstract:

A system for aligning labels on label stock of different sizes with the print head in a printer is disclosed. The label stock is wound around a tubular core, which has a ring shaped groove in its inner surface at the midpoint of its length, forming a roll of label stock. The continuous liner strip contains synchronization holes and identification holes. The system includes a printer having a spindle mounted on a pedestal and holding the roll of label stock to be fed into the printer. The spindle is undersized relative to the tubular core and includes a ring shaped protrusion at its midpoint for engaging the groove in the inner surface of the tubular core. This roll of label stock is automatically maintained centered on the midpoint of the spindle, by its own weight, as it turns around the spindle as the label stock advances. The system also includes an optical detector movably mounted within the printer, for detecting synchronization holes and identification holes in the liner during print head traversal. The system includes a paper feed drive and a print head stepper mechanism.

Abstract:

A font cartridge extrender into which a commerically available font cartridge can be plugged and which plugs into the font cartridge receptacle of a computer printer. The extender includes a novel latching mechnism which attaches the font cartridge to the extender so that the assembly can be conveniently plugged into, and unplugged from, the printer as a unit. The font cartridge is secured to the extender by a spring hook mechanism, which resides in a chute molded into the inside of the top portion of the casing of the extender. The spring hook mechanism is supported in the chute by braces and a pin molded inside the case which is inserted through an aperture in the spring hook mechanism. The spring hook mechanism is actuated by finger pressure on a contact surface.
