摘要： A carrier for a printer, having a single type element, is disclosed. The selection apparatus contained within the carrier is one whereby only a rotary power force plus control signals need be introduced into the carrier. The selection apparatus is comprised of barrel cams having a plurality of channels formed into the periphery of the barrel cams to cause lateral displacement thereof on their drive shaft. The lateral displacement of the barrel cams is converted into a linear motion which is in turn transmitted and converted into rotary motion to position the type element about its rotate and tilt axes. The controls for transmitting signals to the carrier are pneumatic and the pneumatic impulses received by the carrier logic block and actuator blocks activate mechanical latches to insert selector pins into the grooves of the barrel cams. A dual rack and single pinion arrangement is disclosed to convert the linear motion to rotary motion of the type element.
