Description
Technical field
The utility model relates to a kind of data processing equipment with standard data interface, especially a kind of portable, can be easily in conjunction with multiple formatted data treating apparatus and storer have a standard data interface portable data conversion processing unit, belong to the computer external data processing equipment.
Background technology
The original storer of computing machine uses magnetic medium to store data, and used floppy disk, hard disk all belongs to the magnetic medium memory device on the computing machine now.The magnetic medium memory device can be made high capacity memory easily, but has the shortcoming of life-span weak point, poor reliability.And in the present mobile storage, ubiquity can't really move the purpose that stores, and is most of because volume carries inconvenient as external hard disk too greatly, the external CD writer, ZIP, MO... etc., these equipment can provide the larger capacity storage but the maneuverability deficiency.As pocket memory, for example, floppy disk, not only to take volume big for special driver, and energy consumption, noise are big, and travelling speed is slow, occurs physical damage in the use easily.Along with development of semiconductor, the capacity of non-volatile solid state memory is increasing, and price is more and more lower, under this technological accumulation and inheritance, can improve the work and the data reliability of computing machine undoubtedly greatly with the design of alternative floppy disk of solid state memory disc or hard disk.Existing solid state memory disc is of a great variety, and it is the non-volatile solid state memory dish with USB interface rapidly that CF card, mmc card, SMC card and more multiple exhibition are arranged.Carry out exchanges data between their connecting interface structures by separately and the PC.
Because the structure of various cards differs, make PC have to have the connection that various interfaces could satisfy above-mentioned solid-state memory and use, so not only need to increase the PC mainboard different be electrically connected interface, and make the complexity of the structure change of PC or its peripheral hardware.
Present various standard data interface technology, for example USB or IEEE394 etc., become that the PC field widely uses than the new interface technology.Non-volatile memory medium flash memory-FLASH semiconductor technology has than more superior characteristics of storage material such as magnetic medium, and not needing the characteristics of complex drive mechanism based on the storer of this medium, such storer just progressively substitutes existing portable memory device.
On the other hand, integrated circuit card is made up of one or more integrated circuit (IC) chip, and is packaged into and is convenient to the card that people carry; Have temporary transient or nonvolatil data storage capacities, its content can read or supply inter-process, judgement for the outside; Have logic and mathematical operation processing power, be used to discern the information that provides with response external and the processing demands of chip itself.IC-card is as integrated circuit card, a kind of along with development of semiconductor and society arise at the historic moment to improving day by day of requirements such as Information Security, have the integrated circuit (IC) chip of microprocessor and mass storage etc. and be flush-mounted in the card of making on the substrate such as plastics.Because IC-card has adopted current state-of-the-art semiconductor fabrication and information security technology, therefore IC-card has following four characteristics with respect to the jig of other kind: 1, memory capacity is big: there are storeies such as RAM, ROM, EEPROM its inside, and memory capacity can be from several bytes to several megabyte.Can store various information such as literal, sound, figure, image on the card.2, safe: IC-card is implemented its security strategy from several aspects such as hardware and softwares, can control card in the access features of zones of different.Itself has security password memory card, if attempt illegally it to be carried out data access then the card self-destruction, promptly can not read and write.3, not high to network requirement: the safe reliability of IC-card makes its real-time, susceptibility to computer network in application require to reduce, and very meets present case, helps using in the not high environment of network quality.
Because the reliability and the security of integrated circuit card, the use of IC-card is more and more universal, the trace of all visible IC-card from financial product to the personal consumption product, therefore, under the situation that the IC-card consumption increases year by year, PC will become unavoidable trend with combining of IC-card; In like manner, the demand of IC-card card reader also will increase day by day.Because existing computing machine does not have the setting of IC-card card reader, therefore such computing machine can't use IC as its discriminating means.In addition, the communication port on the computer body is limited, and the increasing of the kind of available data input, mode, tend to occur the interface of computing machine by absorb, some external units can't be communicated by letter with it, can only insert use in turn, perhaps can't directly connect at all.
Product based on above-mentioned technology has USB storage, CF card reader, SMC card card reader, IC-card recognizer etc. at present.Like this from the angle of product design and use, do not utilize shared device, there are not to satisfy neatly the variation and the combination of practical application yet, relatively all be to have fixed capacity or function with any a product, make the user have to buy or use one by one function can not be integrated, form these consumption electronic products independently, but also can not upgrade and upgrade.Have again,, do not change owing to carry out modular structure better, and can not reduce cost, improve output better from the manufacturing angle of product.In addition, because demands such as the authentication in PC uses, wireless data exchange exist, integrated day by day interface and data processing equipment too much on the PC, and not configuration more easily.
