Abstract: A convey system includes at least three rotatable shafts disposed in substantial parallel with one another. A pair of first rollers are disposed at each of the at least three rotatable shafts. A first distance between the pair of first rollers is fixed at each of the at least three rotatable shafts. At least a pair of second rollers are disposed between the pair of first rollers at each of the at least three rotatable shafts. A second distance between the pair of second rollers is varied at each of the at least three rotatable shafts. The second distance between the pair of second rollers is shortest at a middle one or two of the at least three rotatable shafts and increased gradually from thereof to two opposite ends of the at least three rotatable shafts. In order to prevent the substrate from sliding on the first and second rollers, a sandblasted treating or a roughness coating is applied on an outer surface of the first and second rollers.

Abstract: A lens actuating device is applicable in a lens module. The lens module has at least a housing and a lens support in the space formed by the housing. The lens actuating device has at least a base disposed in the housing, a piezoelectric element disposed on the base for generating kinetic energy, a clamping component disposed on the piezoelectric element and a linkage element coupled to the lens support and clamped in the clamping component. The clamping component makes a corresponding motion upon receiving a kinetic energy created by the piezoelectric element, which allows a stick-slip friction to be generated in the clamping component to actuate the lens, thereby achieving optical zooming or focusing and avoiding the shortcomings of the prior art using for example a voice coil motor or a stepping motor.
