Abstract
The invention relates to a miniature read/write device which belongs to the class of electronic devices, can be used for inserting MICRO SD memory cards and comprises a USB interface, an SD interfaceand a control module, wherein the USB interface can be connected with an electronic device with a USB socket; the SD interface can be connected with an electronic device with an SD socket; and the control module can be used for switching the read/write device into a card reader state or a switching card state. When the USB interface is connected to the USB socket, then the read/write device is inthe card reader state; when the SD interface is connected to the SD socket, then the read/write device is in the switching card state.
Description
Technical field
The invention belongs to the electronic installation class, be particularly related to a kind of miniature read/write device, especially refer to a kind of for being plugged with the calculating punch state of MICRO SD memory card or the miniature read/write device of adapter state, the miniature read/write device that can have calculating punch and adapter function simultaneously.
Background technology
In recent years, because the progress of science and technology, people are developed and the life of digital electronic product miscellaneous with convenient people, include digital camera, digital camera, the numeral walkman, PDA, mobile phone and mobile computer etc., and when using this type of digital electronic product, just must use storage device with the store digital archives, photograph, music, data such as film or software, and wherein small memory card in conjunction with the flash memory (Flash Memory) of semiconductor (Solid-state electronic) processing procedure, because its volume is less, and easy to carry, replaced the multi-medium data storage device that relatively large discs and disk sheet become a new generation.
Small memory card provides rewritable, need not power supply preserves storage device, the external form of data and lightly reaches preferable shockproof, the antimagnetic and dustproof environmental adaptation characteristic of tool.After asking the city from nineteen ninety flash card (Flash Memory Card), have successively such as CF card (Compact Flash Card), SM card (Smart Media Card), mmc card (Multi Media Card), MS card (Memory Stick Card), SD card (Secure Digital Card), xD card (xD-PictureCard) and T-Flash card (Trans Flash) or the like several small memory cards and release successively.
Yet above-mentioned memory is stuck in when using, and still exists following point to need to improve:
Advantage such as that though small memory card has is easy to carry, memory capacity is big, yet also because the present memory card form that develops is too much, caused and carried trouble, usually needing just has way to read the data of memory card inside through switching or via calculating punch, has caused user's inconvenience.
The content of invention
Fundamental purpose of the present invention is to provide the miniature read/write device of a kind of changeable one-tenth calculating punch state or adapter state.
Technical scheme of the present invention is: miniature read/write device can be for being plugged with MICRO SD memory card (Security Digital Card), and this read-write equipment includes USB interface, SD interface and control module.
Wherein, this USB interface can be for the default electronic installation that connects a tool USB socket, and this SD interface can be for the default electronic installation that connects a tool SD socket;
One control module, and this control module can be calculating punch state or adapter state for switching this read-write equipment, and when this USB interface is connected to USB socket, then this read-write equipment is the calculating punch state, this electronic installation can be for the data in this MICRO SD memory card of access, when this SD interface was connected to the SD socket, then this read-write equipment was the adapter state again, and this electronic installation can be for the data in this MICRO SD memory card of access.
Miniature read/write device, wherein this electronic installation can be one of them persons of associated electrical product such as personal computer, intelligent mobile phone, projector, printer, digital frame, digital camera, mobile computer, satellite navigation system, digital camera, Digital Television, personal digital assistant.
The invention has the advantages that: the USB interface of read-write equipment of the present invention, when being connected to the USB socket of electronic installation, then this read-write equipment is the calculating punch state, the user can utilize this electronic installation to read, write this MICRO SD memory card, again when the SD of read-write equipment interface is connected to the SD socket of electronic installation, then this read-write equipment is the adapter state, the user can utilize this electronic installation to read, write this MICROSD memory card, by this, read-write equipment of the present invention can have calculating punch and adapter function simultaneously, reached the effect of multi-purpose machine, very convenient to the user.
