Abstract: An optical switch module includes a housing, at least two first collimators, at least two second collimators, a relay, and plural prisms. The housing has an accommodating space, a first sidewall, and a second sidewall. The first collimators are located on the first sidewall. Each of the first collimators connects even number of first fibers. The second collimators are located on the second sidewall. Each of the second collimators connects even number of second fibers. The second collimators are respectively aligned with the first collimators. The relay is located in the accommodating space and has a rotation support. The prisms are located on the rotation support and respectively between the first and second collimators. The rotation support is configured to enable at least one of the prisms to be in light transmission paths between the first fibers and the second fibers.

Abstract: Monoclonal antibodies against human Mac-1 are provided. These antibodies can bind to different states of Mac-1 so as to alter the biofunctions of Mac-1. These antibodies can modulate Th1/Th2 cytokine secretions by TLR-activated immune cells and can be used for the treatments of diseases related to acute and chronic inflammatory disorders, such as infectious diseases, and cancers.

Abstract: A position recognition device of a printer includes a bracket, a platform, a positioning gear, and a base. The bracket includes a receiving shaft. The receiving shaft includes a shaft body and a gear portion mounted to the shaft body. The positioning gear is pivotally located to the platform. The positioning gear includes a gear body and a marker connected to the gear body. The gear body and the gear portion are the same size. The base is slidably mounted to the bracket. The base includes a sensor. The positioning gear is located under the sensor to be aligned with the sensor; the gear portion rotates to drive the positioning gear to rotate. The sensor senses the marker to determine an initial position of the receiving shaft for compensation.

Abstract: A paper feeding mechanism includes a paper cassette, a feeding roller, a baffle, and a paper separating apparatus. The paper cassette stores stacks of paper. The feeding roller pulls a sheet of paper from the paper cassette and feeds the sheet of paper into a paper transport path. The baffle is located at a side of the paper cassette. The paper separating apparatus is mounted to the baffle and prevents more than one sheet of paper from being fed into the paper transport path at a time.

Abstract: A transmitting apparatus of a printer, includes an active shaft and a sliding bush. A positioning post is located on the active shaft. A sliding bush is movably mounted on the active shaft. The sliding bush defines a first positioning slot and a second positioning slot. The sliding bush includes an active gear. The sliding bush is configured to move on the active shaft to selectively receive the positioning post in the first positioning slot or the second positioning slot to mesh the active gear with different transmitting gears.

Abstract: A cleaning apparatus for a printer, includes a bracket and a paper transmitting apparatus. The bracket includes a paper tray which is adapted to receive a paper located on. The paper tray defines a cutout. A brush is pivotably mounted below the cutout. The brush is covered by any paper in the paper tray, and is exposed through the cutout when there is no paper in the paper tray. The paper transmitting apparatus includes a carrier and a roller rotatablely mounted on the carrier The paper transmitting apparatus rotates the roller to move the paper in the paper tray. The roller can rotate against the brush when the paper tray is empty to be cleaned of any paper scraps.

Abstract: A paper adjusting device comprises a first and a second limiting plates; the second limiting plate substantially parallel to the first limiting plate; a first driving plate comprising a rotating end and a sliding end, the rotating end of the first driving plate is rotatably attached to the first limiting plate, and the sliding end of the first driving plate is slidably engaged with the second limiting plate; a second driving plate comprising a rotating end and a sliding end, wherein the rotating end is rotatably attached to the second limiting plate, and the sliding end is slidably engaged with the first limiting plate; and an operating member comprising a positioning plate and slidably connected to the first and the second driving plates; wherein the first and the second limiting plates, the second limiting plate are slidable to form a space to align a stack of paper.

Abstract: A paper transmitting apparatus for a printer, comprises a bracket comprising a paper tray mounted thereon, the paper tray is adapted to receive a piece of paper in the paper tray; and a driving mechanism comprising a roller rotatablely mounted on the driving mechanism, a sleeve fitted around the roller, a plurality of grains located on an outer surface of the sleeve to increase a surface roughness of the outer surface of the sleeve, the outer surface of the sleeve rests on the piece of paper, and the driving mechanism is adapted to rotate the roller to move the piece of paper on the paper tray.
