Abstract
A data cassette storage and retrieval device is provided having a gripper which moves linearly on the carrier of a cassette transporter to and from a storage crypt. The gripper carries a pair of pins having hooked ends which rotate into and out of engagement with the flange of a disc cassette. The gripper is operated by a mechanism which includes a chain which is driven around a pair of sprockets. The chain carries a drive pin which is linked to the gripper by way of an actuator plate which slides on the gripper only perpendicular to the path of the gripper. The actuator plate has a cam slot which rotates the pins by driving cam followers on the pins as the drive pin moves on the chain around a sprocket. Control switches and motors on the carrier are connected to the drive controls by a printed circuit board through a hollow shaft on which the carrier rotates on a movable elevator carriage of the transporter. A plastic ribbon cable connected to the printed circuit board is coiled around the shaft to accommodate its rotation.
