摘要： Apparatus for transferring a designated card or card-like article such as a microfiche into or out of a stack of similar cards by producing a separation in the stack at a selected location with a stream of air and moving the designated card into or out of the separation with a vacuum pickup arm. The selected stack location is verified by reading means located outside of the stack and directed at retroreflective marks on the card exposed by the separation.
