Abstract
A driving mechanism has a base member, a moving member, a rotatable first idler, a rotatable second idler, and a rotating member disposed between the first and second idlers. A power-transmission belt is disposed such that it contacts with the first idler, passes between the first idler and the rotating member, contacts with the rotating member, passes between the rotating member and the second idler and contacts with the second idler. A part of the belt contacts with the base member by the first idler and another part of the belt also contacts with the base member by the second idler. With this mechanism, rotational movement is converted to linear movement, and vice versa.
Claims6
A driving mechanism comprising:
- a base member;
- a moving member movable against said base member;
- a rotatable first idler and a rotatable second idler provided on said moving member;
- a rotating member disposed between said first idler and said second idler, and having a shaft extending therefrom to transmit rotary motion of said rotating member to a rotating object;
- a linear drive means for causing said moving member to move in a linear direction;
- and
- a belt which is disposed such that said belt contacts with said first idler, passes between said first idler and said rotating member, contacts with said rotating member, passes between said rotating member and said second idler, and contacts with said second idler, and which contacts with said base member at its part by said first idler and contacts with said base member at another part by said second idler;
- wherein when said linear drive means causes said moving member to move, said rotating member is caused to rotate along said belt thereby causing said rotating object to rotate.
