Abstract: A scanner includes a housing including a first slot, a platform installed on the housing for supporting a document, and an upper casing installed above the platform and rotatably connected to the housing. The upper casing includes a second slot. The scanner further includes a main hinge, connected between the housing and the upper casing. One end of the main hinge is fixed to the upper casing and the other end of the main hinge is positioned within the first slot. The upper case and the housing are connected via the main hinge. The scanner further includes a sub-hinge, connected between the housing and the upper casing, including a shaft and a body. The shaft is installed within the second slot, and the body is installed within the first slot in a slidable manner against the main hinge.

Abstract: A scanner includes a platform, and an upper casing installed above the platform in a rotatable manner. The upper casing includes a housing including a cavity, and two fixtures positioned above the cavity for receiving an end of a positive respectively when the positive is placed into the cavity in a first direction and for receiving an end of a negative respectively when the negative is placed into the cavity in a second direction. The upper casing further includes a light source disposed inside the housing for emitting light. The scanner further includes a scanning module installed under the platform for receiving light emitted from the light source and passing through the positive or the negative so as to generate a sensing signal.

Abstract: A computer input/output (I/O) cable plug retaining seat comprises a retaining cover and a base. The seat can be connected to a computer I/O plug, such as a well-known CENTRONICS cable plug. Four screws are used to secure the cable plug between the retaining cover and the base. A pair of fixing screws secure the retaining seat with cable plug to the rear cover of an equipment shelf so that when a channel unit slides from the card guide of the equipment shelf, the channel unit connector will be led into the guide holes by means of guide pins so that the channel unit connector is precisely aligned with the cable plug. When a user wishes to remove the channel unit from the equipment shelf, the channel unit is extracted directly without having to disconnect the cable. Thus, the objective of rapid assembly and disassembly is achieved.

Abstract: A SCSI cable plug retaining seat includes two guide holes, two guide pins, and a seat. The two guide holes are combined to the upper and lower grooves of the cable plug. The two guide pins are installed to a channel unit connector. The seat has an L shape and the bottom thereof having an opening and has two screws and two screw holes. The retaining base of the present invention serves to fix the cable plug by the screw, and then is locked to the rear covering plate of the shelf. When the channel unit slides into the shelf through card guide, the channel unit connector will be guided into the guide holes by the guide pins so that the channel unit connector is precisely combined to the cable plug. Therefore, the connector can be pulled and inserted rapidly.
