Abstract: The present disclosure provides an extrusion device and a liquid supply apparatus employing the same. The extrusion device includes a connection base, a first elastic valve, a pump base, a second elastic valve and an outlet connector. When the movable assembly of the pump base is driven by an external force and moves toward a first hollow portion of the pump base, the first elastic valve is close, the second elastic valve is open, and the liquid inside the pump base is discharged through the pump base and the outlet connector. When the movable assembly is driven by a resilience of an elastic element and moves away from the first hollow portion, the second elastic valve is close, the first elastic valve is open, and the liquid inside a vessel flows into the pump base through the connection base and the pump base.

Abstract: 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.

Abstract: 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.

Abstract: A sheet separating device having a noise suppressing function is used with an auto document feeder. The sheet separating device includes a sheet separating pad, a sheet separating holder, a resilient element and a noise suppressing element. The sheet separating pad cooperates with a sheet separating roller to separate a paper sheet fed into a sheet-guiding path of the auto document feeder. The sheet separating pad is disposed on the sheet separating holder. The resilient element is sustained against or coupled to the sheet separating holder, so that sheet separating pad disposed on the sheet separating holder is urged against the sheet separating roller.

Abstract: An automatic document feeder is used with an office machine including a scanning module and a transparent substrate. The automatic document feeder includes a main body, an arc-shaped plate and multiple elastic pressing members. The arc-shaped plate is fixed on the main body and includes multiple protrusions and multiple openings. The protrusions are sustained against a surface of the transparent substrate to define a gap between the arc-shaped plate and the transparent substrate for allowing the paper to transport therethrough. The elastic pressing members have first ends coupled to the arc-shaped plate and have second ends partially penetrating through the corresponding openings. The elastic pressing members are arranged in a staggered form to press the object passing through the gap such that a scan zone of the object is in close contact with the transparent substrate to be scanned by the scanning line of the canning module.
