Abstract
Disclosed is magnetic tape cassette transport apparatus for use with a magnetic tape cassette storage and utilization system. Magnetic tape cassettes are transported between locations in the system by means of a cassette transport/accessor assembly, which is actuated by a belt drive system using stationary drive motors. This drive system eliminates the need to mount drive motors on the transport assembly, thus effecting a lighter weight, less complex assembly. The transport/accessor assembly includes two vertical rails rigidly mounted on upper and lower wheel carriages which travel on spaced horizontal rails adjacent to the cassette storage and utilization system. An accessor platform travels vertically on the vertical rails. The accessor platform supports a pair of cassette accessor assemblies which insert and extract a cassette from a location in the cassette storage and utilization system. The power for driving the cassette transporter/accessor assembly is provided by stationary motors coupled to the transport/accessor assembly through sprocket driven, high-yield stainless steel belts. Separate motor and belt drive systems provide selective movement of the transport/accessor assembly in horizontal, vertical and lateral directions.
