Abstract
The present invention relates to a driving device for a scanning module. An active gear wheel and a passive gear wheel are disposed respectively on two rigid frames. These two rigid frames are connected by a rigid component to avoid relative displacement between the two wheels due to external force or change of temperature. The rigid component of the present invention may also be adopted as a guiding track for the scanning module.
Claims9
A driving device for a module, comprising:
- a rigid component;
- a first rigid frame fixed to one side of the rigid component;
- a second rigid frame fixed to another side of the rigid component;
- an active gear wheel fixed on said first rigid frame;
- a passive gear wheel fixed on said second rigid frame;
- a driving belt comprising a strain-controlling apparatus installed therein for adjusting a suitable tension to engage with said active gear wheel and said passive gear wheel.
A scanning module comprising:
- a driving device for the module;
- wherein said driving device further comprises:
- a rigid component;
- a first rigid frame fixed one side of the rigid component;
- a second rigid frame fixed another side of the rigid component;
- an active gear wheel fixed on said first rigid frame;
- a passive gear wheel fixed on said second rigid frame;
- and
- a driving belt having a strain-controlling apparatus installed therein for adjusting a suitable tension to engage with said active gear wheel and said passive gear wheel.
A device for driving a movable scanning module to scan over a scanning area of a plastic scanner body, the driving device comprising:
- a rigid unit further comprising an elongated rigid metal component extending parallel to a scanning direction of the module, a first rigid frame mounted on the plastic scanner body and attached to a first end of the rigid component, and a second rigid frame mounted on the plastic scanner body and attached to a second end of the rigid component;
- an active gear wheel fixedly mounted on the first rigid frame;
- a passive gear wheel fixedly mounted on the second rigid frame;
- and
- a driving belt engaged with said active gear wheel and said passive gear wheel.
