ABSTRACT:
An improved access door for magnetic tape library systems and the like, including a pivotable cartridge-receiving receptacle for facilitating the insertion and removal of cartridges into and out of the system. The receptacle is pivotably mounted to be rotatable between a first position extending at least part way out of the system housing, and a second position wherein the receptacle is at least partially disposed within the housing. A trip lever actuated latch holds the receptacle in the second position, and a spring-loaded lifter rotates the receptacle away from the second position when the latch is released. A damping cam and resilient roller control the rotation of the receptacle and provide limit stops therefor. Optical sensors indicate receptacle position and the presence or absence of a cartridge in the receptacle.
