ABSTRACT:
A disk indicator and ejector for a disk drive mechanism including a base and a clamshell assembly mounted to the base to pivot between an open position for receiving a disk cartridge, and a closed position for drivably engaging it. The indicator and ejector includes a linking member mounted slideably with respect to the base. A cartridge inserted into the mechanism contacts the linking member, moving it inwardly against the force of a tension spring. Simultaneously, a latch rotatably mounted to the linking member contacts a latch block and is thereby rotated against a torsion spring. As the cartridge reaches its centered position, the linking member engages a pin mounted on the clamshell assembly, indicating complete insertion. The clamshell assembly is then closed, moving the pin and linking member further inward and free of the cartridge, and setting the latch in a cocked position. To eject the cartridge, the clamshell is re-opened to move the pin and linking member outward, causing the latch to rotate from the cocked position and lift the linking member free of the pin. The linking member, responsive to the tension spring, then ejects the cartridge.
