Abstract: The aligner mechanism comprises first and second control sleeves keyed to end portions of a shaft. First and second levers are pivotally mounted on the shaft adjacent to the first and second control sleeves for movement between first and second positions. A pinch roller is rotatably mounted on the levers opposite a drive roller. The aligner mechanism also includes an aligner bar having a first leg portion and a second leg portion secured to the first and second control sleeves respectively, and an engaging portion joining the first and second leg portions. The first lever has a projection cooperating with a control member on the first control sleeve and the second lever has a projection cooperating with a control member on the second control sleeve so as to provide lost motion coupling to pivotally move the first and second levers from a first position to a second position.

Abstract: A strain relief apparatus for relieving strain on a cable of an electrical device having a housing with a notched-out portion therein. The strain relief apparatus is generally planar and is mounted directly into the notched-out portion. The strain relief apparatus has a U-shaped channel which is dimensioned to provide an interference fit with the cable after the cable is mounted therein. The design of the strain relief apparatus introduces bends in the cable to further facilitate strain relief if, for example, the cable is accidentally jerked or pulled.

Abstract: A piggyback recorder for use in a printer terminal having a first recorder for printing a first set of data on a document, such as a receipt document. The piggyback recorder is detachably mounted piggyback onto the first recorder, thereby providing a second recorder to the terminal for printing a second set of data on the document. The piggyback recorder comprises a piggyback print member which is capable of printing the second set of data, a mounting member for mounting the piggyback print member directly onto a first print member of the first recorder, a piggyback platen, a second mounting member for mounting the piggyback platen directly onto a first platen of the piggyback recorder, and a solenoid for providing relative movement between the piggyback print member and the piggyback platen.
