The present invention relates to a belt tension adjustment mechanism for use with a device including a main body and a belt pulley set. The belt pulley set includes a belt. The belt tension adjustment mechanism includes a slab, at least two tension pulleys and a fixing element. A tight tension force and a slack tension force are exerted on the opposite sides of the belt to define a tight side and a slack side of the belt when the belt pulley set runs. A counterforce is generated from the tight side of the belt to exert on the tension pulley contacting with the tight side, the slab is moved in response to the counterforce. The slack side of the belt is suppressed by the tension pulley contacting with the slack side such that the slack tension force is adjustable.

An image acquisition module in a transmission device for a scanner is installed in a base of the scanner, a rotating wheel and a first roller are pivotally connected onto two inner sides of the base, and a driving roller is installed below the first roller. A conveyor is respectively put around the rotating wheel, the first roller and the driving roller, and a second roller is pivotally connected onto a place between the rotating and the driving roller and used for withstanding the conveyor between the rotating wheel and the driving roller to allow the conveyor between the rotating wheel and the second roller to be parallel to the conveyor between the rotating wheel and the first roller, and the conveyor is driven by the driving roller to drive the image acquisition module to move.

Transmission device for scanner

A paper guide adjusting mechanism of an office machine includes a main body, a plurality of elastic elements, a transmission member, a plurality of fixing elements and a pressing plate. The main body includes a plurality of confining elements, which have respective recess structures. The transmission member includes a roller axle and a plurality of rollers, wherein the roller axle is partially received in the recess structures and the rollers are sheathed around the roller axle. The fixing elements are disposed in respective recess structures of the confining elements, wherein each fixing element has a base and the base has a first surface sustained against a corresponding elastic element and a second surface sustained against the roller axle. The pressing plate is sustained against the elastic elements.
