Abstract: The integrated point of sale (POS) terminal includes: a calculating device; and a monitor, an input device and an output device respectively electrically connected to the calculating device. An input data is inputted into the calculating device via the input device and displays on the monitor, and then the output data is displayed thereon and outputted from the output device post calculation. In other POS, the input device performs input and output functions, or a touch panel might be the input device.

Abstract: A cooling-fan-free system module includes a housing unit, a circuit module, and a heat radiating unit. The housing unit includes a front and a rear case assembled together to define a receiving space therebetween, and the rear case is made of a highly heat conducting metal material. The circuit module is received in the receiving space of the housing unit, and includes a circuit board, and at least one heat-producing element mounted on and electrically connected to the circuit board. The heat radiating unit includes at least one insulating heat conductor bonded to an inner side of the rear case corresponding to the heat-producing element for transferring the heat produced by the heat-producing element to the rear case, and at least one heat radiating member integrally formed on a back side of the rear case and consisting of a plurality of radiating fins.

Abstract: A mechanism for adjusting an elevation angle of an LCD includes a base, a U-shaped locking arm, a pawl, a release button, an LCD, two rotation shafts and return springs. The base is disposed with a lower casing and a slot. The U-shaped locking arm is defined with an L-shaped hole. The pawl extends through the L-shaped hole and the slot. The release button connects to the U-shaped locking arm. The LCD is disposed with an upper casing. Teeth are respectively disposed at two ratchet arcs of the upper casing and abut against the pawl. The rotation shafts are pivotally disposed at the U-shaped locking arm, the upper casing and the lower casing. The upper casing and the angular relationship between the LCD and the base are restricted by the return springs. When the release button is operated, the angle of elevation of the LCD is adjustable.

Abstract: A computer case includes a lower and an upper cover pivotally connected at a front end to each other via two shafts. The lower and upper covers are provided near two lateral rear ends with an elastic fastening mechanism each for detachably locking a rear end of the lower and upper covers when they are closed to each other. A set of computer equipment is mounted to inner surfaces of the lower and upper covers. When the upper cover is pivotally lifted from the lower cover to fully open the computer case, the computer equipment can be easily accessed to facilitate repair or maintenance thereof.

Abstract: A mechanism for adjusting a rotary angle of an LCD includes: a lower base with a sector rack and arcuate sliding grooves disposed at the top surface thereof; an upper base disposed with an LCD at an upper portion thereof, the bottom surface of the upper base being disposed with sliding posts for movably engaging with the arcuate sliding grooves; and a positioning mechanism including a positioning spring and a positioning push button. The positioning spring constantly urges the positioning push button to mate with one of the protruding teeth of the rack, thereby positioning the rotary angle of the upper base and the LCD. When the positioning push button is inwardly pushed, the positioning push button is disengaged from the protruding tooth thereby enabling the LCD to rotate right and left. The adjusting mechanism further includes an inhibiting mechanism for restricting the rotating scope of the LCD.
