  • Paper sensing mechanism
    Patent number: 4206912
    Abstract: A sensing mechanism for commercially available printing machines wherein paper is automatically fed into the machine sheet by sheet. The sensing mechanism is adapted to be mounted to the machine for permitting it to sense the arrival of a stack of paper at a preselected location as the paper feed table is automatically elevated. When the preselected location is sensed, the table elevation is arrested to prevent the prior art paper "overfeeding" problems.
