Abstract
Abstract A tape punching and reading device having a series of punches which are selectively controlled by a cam element common to all of the punches. A three-armed lever is provided, one arm of which engages the cam element, the second arm is electro-magnetically coupled to an electormagnet, and the third arm has an additional lever pivotally mounted thereon which is interposed between the cam element and the individual punches to effect the punching operation. A photo-electric scanner is provided to read a perforation receiving line of the tape one increment of tape advance beyond the individual punch elements.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
221 words
An apparatus for punching and a tape comprising: a housing; a plurality of punch elements disposed in said housing for punching a hole on a first perforation receiving line on the tape; means for incrementally advancing the tape past said plurality of punch elemenTs; means adjacent the tape for scanning a second perforation receiving line on the tape one increment of tape advance beyond the plurality of punch elements in the direction of tape advance; and means for selectively actuating each of said punch elements including: an electromagnet disposed in said housing; a common cylindrical eccentric cam means for controlling all of said punches; a substantially T-shaped three-armed lever pivotably mounted in said housing between said electromagnet and said eccentric cam means, a first arm of said three armed lever being engageable with said eccentric cam means, a second arm of said three armed lever being selectively electromagnetically coupled to said electromagnet; a second lever pivotally mounted to the third arm of said three-armed lever and extending between said eccentric cam means and a respective punch element; and a spring means for constantly biasing said second lever into engagement with said eccentric cam means whereby the free end of said second lever pushes a respective punch into the tape upon rotation of said eccentric cam means when said electromagnet is energized.
