Abstract
The utility model relates to a kind of write type Novel USB flash disk alternately, it is characterized in that: comprise USB flash disk main body, simple and easy display screen, data line, USB plug, USB joint, upturning key, return key, determine key, downturning key etc.Described simple and easy display screen is arranged on USB flash disk main body middle and upper part, described data line is by USB flash disk main body Base top contact, and connect USB plug, described USB jiont treatment is in USB flash disk main body one side, can be used for being connected with USB plug, described upturning key, return key, determine that key and downturning key are arranged on USB flash disk main body middle and lower part, be positioned at simple and easy display screen below.It can realize between USB flash disk read-write alternately for existing USB flash disk, can be independent of that network is shared and computing machine read-write, and autonomous mutual read-write has that data transmission efficiency is high, advantage easily and efficiently.
Description
Technical field
The utility model relates to message exchange, electronic processing technology, contacts closely, particularly a kind of write type Novel USB flash disk alternately with electronic information technology.
Background technology
USB flash disk is mainly used in carrying out message exchange with personal computer (PC), realizes data transmission, transfer and storage.Its cardinal principle is: computing machine transfers compound binary digital signal instructions such as (add distribution, check) storehouses read-write to USB chip adaptable interface binary digital signal, the appropriate address stores binary data of distributing to EPROM2 storage chip by chip processing signals, realizes the storage of data.EPROM2 data-carrier store, its control principle is the high low value of the voltage of Control of Voltage gate transistor (high electronegative potential), the junction capacity of gate transistor can be preserved magnitude of voltage for a long time.
And general USB flash disk mainly depends on personal computer now, realize and driving and data transmission, cannot realize autonomous read-write and data sharing and transmission.What main limitation was that EPROM2 storage chip realizes is only storage, and can not realize operability.But on market, Mp3 player has central processing unit and can realize the operation to file, data.
Utility model content
The utility model is intended on the basis of existing USB flash disk, chip is transformed, made it have autonomous classification, file and data manipulation function, thereby realize the data interaction read-write between USB flash disk, break away from the dependence to personal computer, make directly to carry out between USB flash disk mutual read-write operation.Its technical scheme adopting is as follows:
Write type Novel USB flash disk, comprises USB flash disk main body, simple and easy display screen, data line, USB plug, storage chip, button cell, USB joint, upturning key, return key, determines key, downturning key alternately.Described simple and easy display screen is arranged on USB flash disk main body middle and upper part, described data line is by USB flash disk main body Base top contact, and connect USB plug, described USB jiont treatment is in USB flash disk main body one side, can be used for being connected with USB plug, described upturning key, return key, determine that key and downturning key are arranged on USB flash disk main body middle and lower part, be positioned at simple and easy display screen below;
Above-mentioned write type Novel USB flash disk alternately by thering is copying on market, paste, the chip technology of the MP3 player inside of the basic operation such as shearing is applied on the EPROM2 storage chip of USB flash disk, and carry out technological improvement in the USB interface of existing USB flash disk, change into and can realize mutual Embedded interface, thereby realize the connection of two USB flash disks;
Above-mentioned write type Novel USB flash disk alternately inside is provided with button cell as power supply, for the file operation between USB flash disk provides the energy.
The utlity model has following advantage: can realize read-write alternately between USB flash disk, can without personal computer in the situation that, carry out data transmission and share, greatly improve data transmission efficiency, especially at USB flash disk, use the ground such as industry park, cultural industry district, campus frequently, being independent of network shares and computing machine read-write, autonomous mutual read-write, has advantage easily and efficiently.

Embodiment
Below in conjunction with accompanying drawing and example, the utility model is described in further detail:
As shown in Figure 1, write type Novel USB flash disk, comprises USB flash disk main body 1, simple and easy display screen 2, data line 3, USB plug 4, storage chip 5, button cell 6, USB joint 7, upturning key 8, return key 9, determines key 10, downturning key 11 alternately.Described simple and easy display screen 2 is arranged on USB flash disk main body 1 middle and upper part, described data line 3 is by USB flash disk main body 1 Base top contact, and connect USB plug 4, described USB joint 7 is arranged on USB flash disk main body 1 one sides, can be used for being connected with USB plug 4, described upturning key 8, return key 9, determine that key 10 and downturning key 11 are arranged on USB flash disk main body 1 middle and lower part, be positioned at simple and easy display screen 2 belows.By thering is copying on market, paste, the chip technology of the MP3 player inside of the basic operation such as shearing is applied on the EPROM2 storage chip 5 of USB flash disk, and carry out technological improvement in the USB interface of existing USB flash disk, change into and can realize mutual Embedded interface, thereby realize the connection of two USB flash disks, in addition, in USB flash disk inside, be provided with button cell 6 as power supply.
While using on personal computer, without USB flash disk internal electric source, drive, and can give button cell 6 chargings, to extend its service time, realize the data transmission between personal computer and USB flash disk simultaneously, when reading and writing alternately, two USB flash disks can utilize self-contained power supply, the USB plug of a USB flash disk 4 is connected on the USB joint 7 of another USB flash disk, utilize the simple and easy display screen 2 of USB flash disk main body 1, can show internal file, data, and by using upturning key 8, return key 9, determine key 10 and downturning key 11, realize and simply copying, shear, the file operations such as deletion.
With way of example, the utility model is illustrated above, but the utility model is not limited to above-mentioned specific embodiment, all any changes of doing based on the utility model or modification all belong to the claimed scope of the utility model.
