ABSTRACT:
Gate mechanism for a data cartridge library system including an upstanding lever arm having a laterally extending tab formed at its upper end and a generally Z-shaped member extending from its lower end, the distal end segment of the Z-shaped member forming a light-breaking flag disposed between an optical switch. The lever arm is pivotally attached proximate its lower end to a pivot member that allows the lever arm and its appendages to be rotated about orthogonal axes. An actuator is attached to the lower end of the arm so as to rotate it about one of the axes, and a spring is attached to the lower end of the lever arm to return the arm to a neutral position following its rotation about either axis. The gate mechanism is useful in blocking entry to a drive unit, limiting ejection distance of a cartridge ejected from the drive unit, and indicating when a cartridge extends out of the drive unit.
