Abstract: A multi-function writing implement includes a pen shaft, a colored pen assembly, and an erasing pen assembly. The colored pen assembly is arranged at one end of the pen shaft. The colored pen assembly includes a cartridge seat, a nib seat, a plurality of colored cartridges, a plurality of relay cartridges, and a plurality of colored ink cotton tubes. The erasing pen assembly is arranged at the other end of the pen shaft opposite to the colored pen assembly. Only one end of the pen shaft may have at least two colors for providing the user to use different colors and the user is not necessary to use two nibs respectively arranged at two ends of the pen shaft by replacing in turn.

Abstract: A transformer structure includes an iron core and coils constituted by first, second, third and fourth windings, where the iron core has a first, second and middle flanges. The first flange is respectively configured with first and second terminal electrodes, the second flange third and fourth terminal electrodes, and the middle flange first and second center taps. The first winding is respectively in connection with the first terminal electrode and first center tap, the second winding the first center tap and third terminal electrode, the third winding the second terminal electrode and second center tap, and the fourth winding the second center tap and fourth terminal electrode. Whereby, the present invention can obviously increase the Hi-Pot safety distance of the transformer, and can thus have better high-pressure resistance.

The relay cartridges are respectively connected to the colored cartridges and arranged in the cartridge seat. The colored ink cotton tubes are respectively connected to the relay cartridges and arranged in the pen shaft and the cartridge in parallel. The erasing pen assembly is arranged at the other end of the pen shaft opposite to the colored pen assembly.

Abstract: An optical disk drive includes a body, a tray, a first fastening structure, and a second fastening structure. The body has an opening. The tray is coupled to the body and movable at the opening. The first fastening structure is disposed at the body, and the second fastening structure is disposed at the tray. When the tray is situated in the body, the first fastening structure and second fastening structure are correspondingly fastened to each other to restrict the displacement of the tray along the vertical direction in the body.

Abstract: There is provided an optical disc drive designed for reading data stored in an optical disc. The optical disc drive includes a body, a driving module, a body wrapping unit, and an access module designed for reading data stored in the optical disc. The driving module and the access module are both disposed in the body. The driving module has a circuit board and a driving element disposed on the circuit board, and the body has a plurality of latching structures. The driving mechanism is secured to the body with the use of the latching structures, and the driving mechanism is secured at one side of the latching structures. Moreover, the body wrapping unit used to cover the body has at least a limiting portion which is positioned at another side of a portion of the latching structures.

Abstract: A housing structure. The housing structure includes a first case and a second case. The first case includes a first inner wall with an extension plate. The length of the extension plate is h. The second case includes a second inner wall with a rib. A notch is defined between the rib and the second inner wall, and the depth of the notch is h. When the first case is joined with the second case, the extension plate engages the notch.

Abstract: The present invention is related to a portable storage device for personalizing computer, wherein an application program is stored in the portable storage device. The portable storage device has a connector for connecting to the connecting port of an electronic device. When the connector and the connecting port are electrically connected, the application program is executed to output the personal profile of the portable storage device to the electronic device, or the personal profile of the electronic device is stored in the portable storage device. Thus, the user can readily change the personal profile in the operating system, so that the task may be accomplished accurately and efficiently, and the problems caused by the operational interface as described in the prior art may be avoided.
