Description
[technical field]
The utility model relates to a kind of memory and links USB commentaries on classics card reader/writer, relates in particular to a kind of the connection with computing machine with the memory that makes things convenient for data storing to read to link USB commentaries on classics card reader/writer.
[background technology]
In order to cooperate the appearance of digital product, digital camera, Digital Video, mobile phone and other some digital products the small memory card of many different size shapes have appearred, for example on the market.Because this type of memory card is compact, not only meet the needs of digital product storage data, and its capacity reached all more than the megabyte, therefore for digital products such as mobile phone, very convenient really in the use.
Especially the microSD card of extensively using now will become the flash memory of specification minimum in the world, and size has only 11x15x1mm, and it will be compatible fully with the TransFlash form of SanDisk, therefore can be general with the SD or the product of miniSD card.And all be equipped with the camera lens of high-res in the present mobile phone, can also download video content, and can be compatible with computer information, therefore need removable flash memory to support these functions more, and microSD card De Chu Now can fully satisfy the requirement of aspects such as being applied to size, speed, performance, swap date and security.In the employed flash memory in all parts of the world, leading at present with the SD flash memory.Because it has possessed the fluency of data conversion, therefore comprises other numerical digit products such as digital still camera, video camera, printer, notebook computer, all support The note Yi card.
When these microSD cards uses combine with product, now corresponding product (mobile phone) comprises a card inserting mouth, be used to read the data of microSD card inside, but, as desire to read the data of microSD card internal reservoir, and perhaps on the microSD card, writing other data, still must handle by computing machine, but the standard specification of this type of microSD card and non-computer does not have adaptive device to connect memory card and computing machine.
This shows the card reader/writer that needs a kind of microSD card and computing machine to read and write data mutually.Thereby realization data write.
[summary of the invention]
At the problem of above-mentioned existence, the purpose of this utility model provides a kind of memory that can realize the data-switching between microSD card and the computing machine by the most common USB interface and computing machine line and links USB and change card reader/writer.
For realizing above-mentioned purpose, the technical solution of the utility model is to provide a kind of memory to link USB changes card reader/writer, and it is characterized in that: comprise a housing, described housing has a microSD card slot, inserts for the microSD card; One USB interface is in order to be connected with computing machine.
Also comprise a holding unit in the described housing, microSD card receptacle, microSD card modular converter circuit board, wherein, holding unit is fixed in the containment vessel of the USB interface that the one end extends in the housing; MicroSD card receptacle is in order to ccontaining microSD card; Described microSD card modular converter circuit board comprises Card Reader coupling part and USB coupling part, carries out circuit with microSD card receptacle, USB interface respectively and is connected.
The utility model comprises that also one buckles.
Characteristics of the present utility model are: a kind of computing machine USB interface of the present utility model and a kind of card reader utilized is being provided, this card reader can directly be connected with computing machine by aforementioned calculation machine USB interface, make computing machine directly read microSD card internal storage data, and make the read-write operation of computing machine fast convenient more by high-speed interface; And for microSD card user, be more convenient for the exchanges data of microSD card.
