ABSTRACT:
A sequentially operated machine employs two positionable members, a movable center selection piston member and a movable transducer member for accessing a record storage member selected by the central piston member. Making the record storage member available to the transducer reuires a predetermined time delay. Accordingly, the servomechanism powering the selecting mechanism has a high response, while a following servomechanism transporting the transducer has a low response such that cost is reduced while not adversely affecting access time to the record member.
