    摘要： A rotary/linear shuttle mechanism, particularly suitable for use in shuttling the carriage of a dot matrix line printer, is disclosed. The rotary/linear shuttle mechanism includes a pair of stiff, thin bands--one long and one short (35,41). The bands are formed of an inelastic material, such as steel or titanium. Each band has a centrally located loop (formed by a necked down portion of the band passing through a window in the band), and a pair of outwardly extending arms. The loop (67) in the long band (35) is wrapped around, and affixed to a motor pulley (33). The pulley is mounted on the shaft of a low inertia motor (31), such as a moving coil type DC brush motor. The ends of the arms (66,68) of the long band (35) are affixed to the periphery of a large diameter pulley (37). The large diameter pulley is mounted on a shaft (75) that also supports a small diameter pulley (39). The loop in the short band (41) is wrapped around, and affixed to, the small diameter pulley (39); and, the arms of the short band are affixed to the carriage (11) to be shuttled. AC power of a suitable frequency, magnitude and waveform is applied to the low inertia motor, causing the shaft (43) of the motor to oscillate. The resultant oscillatory movement of the motor pulley (33) causes the large diameter pulley (37) to oscillate resulting in the oscillation of the small diameter pulley (39). The rotary oscillation of the small diameter pulley (39) causes linear oscillation of the arms of the short band (41) and, thus, causes linear oscillation of the carriage (11).
