Pin sensing system
US 3795402 A
Abstract
A pin sensing system, based on the definition of pin sensing zones by intersecting reflecting and transmitting optical paths, transmits "pins standing" information to distinct optical projection and data printing systems. The intersecting, reflecting and transmitting optical paths originate in front of the head pin position and converge in the direction of the pit end of the lane.
