Description

All-in-One memory card switching device

Technical field

The utility model relates to a kind of memory card switching device, particularly relates to a kind of memory card switching device that reads multiple memory card data formats and changed output.

Background technology

Digital product is a large amount of to come out and the fast-developing multiplication that brings quantity of information, wherein little with volume again, memory card easy to carry is the data storage medium that the most generally uses, it can be used in digital still camera, PDA, mobile phone, the message playback equipment, and can extract at any time to substitute and carry out Data Processing, and the storage volume of the memory card that sells can be a kind of being extensive use of and the high memory storage interface of compatibility up to 4～6GB on the market at present.

Yet develop the memory card of its specific standard separately because of manufacturer, be convenient user, the All-in-One memory card switching device that can read multiple memory card form simultaneously just arises at the historic moment, referring to Fig. 1 is a kind of " All-in-One card reader " that is sold on the market, this kind All-in-One card reader has a printed circuit board (PCB) 10, one controller 11, one socket 13, one first slot 15 for the insertion of MS (memory stick) memory card, one second slot 16 for CF (compact flash) or the plant of MD (microdrive) memory card, one for MS Duo (memory stick duo), the 3rd slot 17 that memory stick Pro Duo or miniSD memory card insert, and the card reader that combines of the 4th slot 18 that plugs for the xD memory card.

As shown in Figure 1, the all indivedual welderings of each slot 15～18 tie on this printed circuit board (PCB) 10, so this printed circuit board (PCB) 10 must provide enough installation surface could place all slots 15～18 simultaneously, thus, the shared volume of whole card reader increases relatively, concerning commercial affairs or travelling personage, the burden that invisible increase is carried.

On the other hand, PCMCIA (Personal Computer Memory Card InternationalAssociation) is an international organizations that is found in 1989, mainly be for formulating the international standard of memory card, with this specification of the most normal use of notebook computer, PDA, digital still camera, digital television, set-top box (set-top boxes) etc. also all have corresponding product can use the card of PCMCIA specification.

In order to cooperate the demand for compact expanding device of notebook computer, PCMCIA has formulated the specification of three kinds of thickness: Type I, Type II and Type III mainly are used in memory card, interface card, adlib, data card and the networking of general notebook computer, the device of external hard disc; Recently PCMCIA more makes ExpressCard ^TMThe interface form.Therefore, if more kinds of memory cards can be read the terminal interface is integrated in the volume of more simplifying, collocation ExpressCard ^TMThe interface expansion demand, adapt to notebook computer or accompanied electronic equipment be particular about compact and be easy to carry about with one functional, believe more to meet trend now.

The utility model content

The purpose of this utility model is to provide a kind of and can read eight kinds of data storage interfaces and be integrated in the same slot, at last with data with ExpressCard ^TMThe All-in-One memory card switching device of interface output.
