<p>A meter base drive assembly (4) is a part of a postage meter base (2), to which a postage meter is mounted. The assembly includes envelope drive (62), a tape dispenser (86) and a print head drive (84) mounted to a base frame (12). The drive assembly includes a motor drive (6), pivotally mounted (10, 14) to the frame, which drives a pulley (8) in a first rotary direction. First, second and third driven pulleys (16, 18, 56) are operably coupled to the envelope drive, print head drive and tape dispenser respectively. A dual pulley (20), including first and second pulley elements (28, 53), is pivotally mounted (34, 36 ; 102, 104) to the frame. One side (30) of a first drive belt (26) engages the drive pulley and one of the first and second driven pulleys. The second side (32) of the first drive belt engages the first pulley element. A second drive belt (52) engages the second pulley element and the other of the first and second driven pulleys, so that the first and second driven pulleys are rotated in opposite rotary directions.</p> |
