Abstract: An active stylus having physical writing function includes a tip shell including a first opening and a second opening, a first electrode including a first end protruded through the first opening of the tip shell and including a second end protruded through the second opening of the tip shell and entered a main body housing of the active stylus, wherein the first electrode includes conductive material. The tip shell includes non-conductive material. The first end of the first electrode is configured to leave colored traces on an object by physical friction caused between the first end of the first electrode and the object.

Abstract: A book scanner with a minimized scan margin scans an open book, which has a first inner surface, a second inner surface and a binding section. The book scanner includes a book supporting structure and a scanning module. The book supporting structure is composed of a transparent first portion and a second portion, which define a first angle smaller than 180 degrees and a ridge. The scanning module scans the first inner surface of the book contacting the first portion. The scanning module can scan a scan region of the first inner surface and a distance from the scan region to the ridge is substantially shorter than 4 millimeters.

Abstract: A multi-function peripheral which facilitates maintenance includes a scanner unit, a printer unit and a support assembly. The support assembly includes a top platen, on which the scanner unit is placed, a bottom platen, on which the printer unit is placed, and a vertical support column for connecting the top platen to the bottom platen. The top platen is capable of being rotated about the vertical support column relative to the bottom platen, or the vertical support column is retractable to enlarge a buffer space above the printer unit and to facilitate the maintenance of the printer unit.

Abstract: A continuously adjustable illuminating apparatus includes a base, a light source, a reflector and a continuously adjustable mechanism. The base has a through hole, and the light source movably passes through the through hole and emits light rays. The reflector surrounds the base and is mounted to the base to collect the light rays and reflects the light rays for output. The continuously adjustable mechanism may continuously move the light source so as to continuously adjust a relative position between the light source and the reflector.

Abstract: A finely adjustable optical mechanism includes a base, a lens seat mounted on the base, a mirror set mounted on the base. A lens and an image sensor are mounted on the lens seat. A link is provided between the lens seat and the base. It is possible to move the lens seat relative to the base by rotating the link to move the lens seat or the base. Accordingly, the relatively positional relationship between the lens seat and the base can be finely adjusted.
