Customer Replaceable Cash Receipt Cutter

Disclosed is a simple cash receipt cutter that attaches to a point of sale printer via molded snap latches. The plastic materials are chosen to provide a mix of wear resistance and lubricity. The cutter station may be easily replaced by the customer.

A two-piece molded plastic frame 1 contains pins and spacers that locate, retain, and provide clearance for the hardened steel cutting blade 2. A plastic bearing 3 is keyed to the cutter blade and slides freely in guide ways 4, molded into the top frame. A slot, molded in the bearing, engages the pin 5 on the spring-returned rotary actuator 6. Molded into the underside of the frame are locating bosses 7 and snap latches to mount the rotary actuator. A throat 8, molded into the frame, provides a guided entry path and constraint for the receipt paper.

The blade 2 and the bearing 3 are inserted into the frame 1. Integrally molded bosses act as rivets and are heat or ultrasonically upset to fasten the assembly. The frame assembly also acts as a shield to provide for safe handling of the blade.

The rotary actuator 6 is then aligned to its locating holes 7 in the frame and to the slot in the bearing. Plastic latches molded into the underside of the frame secure the rotary actuator to the frame assembly.

The completed assembly may now be attached to the printer via locating pins and plastic snap latches 9 that are molded into the top access cover of the point- of-sale printer.
