Abstract
A tape threading apparatus (20) includes a tape guide arm (22) having a spring-biased elbow (32). The arm (22) is coupled for rotation with a rotatable shaft (24). The shaft is provided with a barrel cam (76, 92) for a third dimension of movement. A drive mechanism includes two gears (88, 90) that overlap to permit vertical slippage in the third dimension of movement. An arm guide cam slot (102) provides a directional orientation for movement of the arm (22) along a tape travel pathway (100).
