Abstract: An enhanced electronic card structure includes a circuit board, a top cover board, and a bottom cover board. The circuit board has multiple front front and rear contact points. At least one fixing hole is defined between any two adjacent front contact points. The top cover board has a front edge defined therein multiple gaps, each aligned with one front contact point and corresponding rear contact point. Any two adjacent gaps are separated by a rib, each rib having a bottom face extended thereform a fixing tip aligned with the fixing hole. The bottom cover board has a surface formed thereon multiple fixing joints, each aligned with one fixing tip at the bottom of the rib, so as to make the fixing tip pass through the corresponding fixing hole to be fixed to the corresponding fixing joint.

Abstract: A memory card casing includes a plastic framework, and upper and lower metal covers that could be conveniently assembled to two sides of the plastic framework. The metal covers are fastened to each other via fastening means spaced on perpendicular wall portions of the metal covers. Each of the fastening means includes first and second fastening plates. The plastic framework is provided with retaining means, each of which includes a neck portion inward projected from and perpendicular to inner wall surface of the plastic framework and an expanded head portion in front of the neck portion.

Abstract: An integrated, secured point-of-sale (POS) system comprises a cabinet housing computer electronics, a keyboard, a monitor, and a customer display assembled in a modular construction. The cabinet has a cover that is connected to a base using a pair of release rods for easy assembly and disassembly without the use of tools. The keyboard is attached to the cabinet with quick-release connectors. Security locks are provided in the keyboard to protect proprietary data stored in the POS system. The cabinet includes a printer platform for supporting a printer and a display platform for supporting the monitor and customer display. The monitor is connected to the display platform for two-dimensional displacement using a skewed rod extending from the monitor and cooperating with a guide slot in the display platform or vice versa. A monitor mounting mechanism employing a simple yet efficient pin-and-slot connection provides precise tilt-and-swivel motion of the monitor relative to the display platform.

Abstract: A multiple-key key assembly includes an integrated key top and key base unit with a built-in stabilizer. The key top includes a key plunger for mating with a key plunger guide provided in the key seat of a keyboard to support the key assembly on the keyboard and for making key stroke contacts with depression of the key top. The stabilizer includes a swing rod connected in a movable fashion between the key top and the key base. When eccentric actuation occurs from the top of the key top, the eccentric force is deflected by the swing rod and uniform force transmission is achieved to provide smooth operation of the integrated key. A support plunger provided in the key top is guided by a support plunger guide provided in the key base for added stability. The integrated structure with the built-in stabilizer allows the integrated key assembly to be adapted to a wide range of multiple-key applications, including double and quad keys.

Abstract: A security electric cash drawer includes a shell having two inner lateral walls, a front opening, a bottom opening and a front securing plate, a bottom plate having a front bent end and inserted into the shell to be held secured to the shell for covering the bottom opening, a pair of tracks respectively mounted on the two inner lateral walls, and a drawer slidable along the pair of tracks and inserted into the shell from the front opening.Further, the security electric cash drawer includes a securing piece inserted from an inside of the shell for fixing the bottom plate in place in order to avoid the cash drawer from being externally disassembled. This invention also provides a tray having a plurality of detachable clips for conveniently managing kinds of cashes.
