Abstract

This idea addresses this issue of possibly cutting your hand/wrist while removing or replacing a paper roll. Tear bars on current printers are nice feature for tearing receipts, but it can also be a safety concern, especially during the process of removing or replacing a paper roll. Because of the location of the tear bar in respect to your hand motion of removing/replacing the paper roll, the sharp edges of the tear bar are hard to avoid.

Safety Cover for Printer Cutter Blades

The idea is having a shroud or housing unit around the tear bar when the paper cover is in open position. This is the cover position when the operator is removing the paper core and installing new paper roll, or just removing a paper roll. There could be other less frequently replaced parts that the operator can reach when the cover is open. See the parts descriptions in Figure 1.

The housing unit is spring loaded, where it springs up when the paper cover is in the open position to protect/cover the tear bar, and it is sprung back down to expose the tear bar when the paper cover is closed (Figure 2). There is a mating latch on the paper cover that moves the housing out of the way when the cover is closed.
