Abstract: The invention is a modular and wooden blocks type of CD rack. The CD storage comprises of several individual modules. And with different combinations of different modules, one can assemble different types of racks for storing CD and CD box. The modules comprise side plate, end plate, back plate, bottom feet, stand plate, support beam, connection structure. Because of the different modules, multiple types of CD rack such as vertical, horizontal and plane type CD racks can be structured and therefore it is capable of storing CD jewelry case, CD boxes and other objects. The framed racks are stackable unlimitedly in both vertical and horizontal direction.

Abstract: The invention is related to a mechanical device and method for labeling sticker on business card type of CD, and the device includes a sticker accepting base, a CD accepting base and a resilient unit. The said sticker-accepting base has an accepting plane for placing labeling stickers and the center of the said accepting plane is a central hole. Another side of the accepting plane is with a support foot base for standing up the sticker accepting base. The said CD accepting base is as an “U” type of module and the upper side is with two vertical and parallel side plates along two edges of the base, therefore, the turnabout of sticker accepting plane is limited and the vertical movement of CD can be guided. The top ends of the two side plates of the CD accepting base are ladder type of planes and the said ladder planes are for placing two parallel straight edges of CD. Central part of the CD accepting base is a positioning central pillar.

Abstract: A CD cleaning and labeling device includes a basin-shaped upper case, a lower case engageable with the upper case, a base having a concave base center located inside the lower case for providing a CD supporting surface, and a movable sticking seat located inside the base center. The upper case is furnished with at least one CD cleaning means. The lower case has a base for carrying a CD or a CD label. The sticking seat has a brim for allowing a CD label with a center hole to be sleeved along and a top surface for resting the CD. The sticking seat is movable between an extension position and a retracting position. While in the retracting position, the top surface of the sticking seat is lower than the supporting surface of the base so as to allow the CD to rest upon the supporting surface of the base.

Abstract: A CD cleaning and labeling device comprises an upper case engageable with a lower case to form a compartment therein. The upper case has an actuating means to drive a driving means and at least one cleaning means. The lower case has a base for carrying a CD or a CD label, a driven means engageable with the driving means and a movable sticking seat which may be lifted above the base at an extension position for receiving the CD or be pressed downward by means of the closed upper case for performing the CD cleaning or labeling operation.

Abstract: An external connecting interface which is capable to transmit both the power supply and digital signal of the computer motherboard to an external peripheral device through a single socket. The socket has a plurality of pins which includes at least two power transmission pins and a plurality of signal transmission pins. The power pins of the socket are coupled with the power supply of the computer motherboard for power transmission, while the signal transmission pins are coupled with the interface slots of the computer motherboard for signal transmission. A control chip may be included in the external connecting interface for controlling the signal transmission pins to couple with one of the interface slots. By using a cable to connect the external peripheral device to the socket, both the digital signal and power supply of the computer can be transmitted in the same time. It is convenient, has high compatibility, is low cost, and does not need additional external power supply or program driver.
