Abstract

PURPOSE: Install a latticed light-source on one of the side-walls of a vacuum tube which sucks in the slackened part of magnetic tapes or record-paper, and at the same time install on the other side-wall a latticed light converging optical system. Thus, a smaller-in-size and highly accurate system is accomplished.
