摘要： A scanner has a hollow base, a bracket securely received in the hollow base and having a paper-pressing bar mounted onto the bracket, a top seat securely provided to one side of the hollow base and a top cover mounted on top of the top seat. The top cover has a pressing plate extending into an interior of the top seat and a pair of pressers each extending to engage with and abut the paper-pressing bar. The paper-pressing bar has a driven gear mounted on one distal end thereof so as to correspond to a driving gear of the bracket and a rubber sleeve mounted on the paper-pressing bar to increase a friction. The paper-pressing bar is releasably mounted on a pair of cutouts in the bracket so that the paper-pressing bar is able to move vertically relative to the bracket.

摘要： The present invention discloses an improved wireless audio output assembly for projectors, which comprises a system unit having a projector circuit therein and a projector lens disposed on the exterior of the system unit, and the system unit has a card-type wireless audio output circuit installed therein and a wireless active speaker installed on the exterior of the system unit, so that a projector can be used as a standalone device without connecting to external cables to read data from a memory card, view video images, and read audio/video signals of an optical disk. The projector can be upgraded to the user's desired wireless audio output circuit by inserting various different cards for the expansion.
