Automatic Strip Printer

Computer printouts are provided by a low-cost strip printer, using a dot matrix print head device or the like, controlled by a combination of computer commands and feedback signals indicating print medium movement.

Print medium 10, shown here as paper, is stored on reel 11 mounted to base plate 12. A dot matrix print head 15 is positioned in the line of travel of paper 10 and could be a dot matrix wire printer somewhat similar to that shown in Patent 3,108,534, "High Speed Printer", by Preisinger, a dot matrix punch. a bar matrix printer or the like. A ribbon mechanism could be contained within head 15 with a follower wheel arrangement, not shown, for moving the ribbon as the paper moves, or with means for incrementally moving the ribbon as print commands are executed by head 15.

A small DC motor 16, with a ball reduction drive, can be used for moving the paper 10 in response to actuating signals introduced to terminals 17 and 18. These actuating signals could be manually switched, computer originated or both. Pressure rollers 19 and 20 grip paper 10, and an emitter 21 with associated detector 22 can be used to sense movement of the paper and generates pulses at output 23 representative of that movement. Normally both pressure rolls 19 and 20 would be mounted on plate 12. Alternatively, motor 16 could be omitted entirely and movement imparted to the paper manually.

The computer or other controlling mechanism responds to motion indicating s...
