Single reel cartridge with improved housing assembly

摘要

A single reel data tape cartridge housing includes a base and a cover. The base includes four outer side walls which are formed with at least one step such that the outer walls step to a decreased thickness toward their free end. The cover includes four outer side walls which are formed with at least one step such that the outer walls step to a decreased thickness toward their free end. The base and cover also include four inner walls which are formed with two steps such that the inner walls step to a decreased thickness toward their free end. The inner and outer walls of the cover complementarily mate with the inner and outer walls of the base. A projection can be placed within pockets in the base and cover to locate the base and cover during assembly.
