<p>A driving mechanism has a base member (10), a moving member (12), a rotatable first idler, a rotatable second idler (34), and a rotating member (30) disposed between the first and second idlers. A power-transmission belt (40) is disposed such that it contacts with the first idler, passes between the first idler and the rotating member (30), contacts with the rotating member (30), passes between the rotating member (30) and the second idler (34) and contacts with the second idler (34). A part of the belt contacts with the base member (10) by the first idler and another part of the belt also contacts with the base member (10) by the second idler (34). With this mechanism, rotational movement is converted to linear movement, and vice versa. <IMAGE></p> |
