Tape perforators belong to the list of very important devices for the output of information from computers and automatic systems. The report describes a three-speed tape perforator, PL-75-100-150 which provides perforation of tape at three speeds. The main thing in the development and study of this perforator was the creation of a block diagram of code selection which provides tape perforation at any speed, i.e., from 0 to 150 lines/second.
