Abstract
The invention provides a memory-card expanding and capacity combining card reader which comprises a body with a USB joint and a plurality of memory card slots, a circuit board is built in the body, and the circuit board is mainly comprises a control and power supply module, a read-write module and data buses connecting the memory card slots. The read-write module detects and obtains the inserted card capacity of each memory card slot, and sequentially addresses the memory card slots, and the read-write module is controlled by the control and power supply module. The control and power supply module is in communication connection with a host computer through the USB joint, and obtains power through the USB joint. The memory-card expanding and capacity combining card reader detects and obtains the inserted card capacity of each memory card slot, and sequentially addresses the memory card slots to really combine the capacity of the memory cards. A user uses the memory cards in a computer as an integrated memory instead of simply reading a plurality of memory cards, and the problem of reutilizing memory cards with small capacity is solved.
Description
Technical field
The present invention relates to a kind of card-reading apparatus, the connection being specifically related to a kind of exented memory card holds card reader.
Background technology
In order to meet the individual demand of people for mobile phone EMS memory, modern many mobile phone brand and models are all provided with external memorizer, namely our usually said mobile phone EMS memory card.Along with development and the jumbo data storage requirement of people of memory technology, many mobile phones or compatible 16G and above Large Copacity RAM (random access memory) card, or mobile phone fixed memory capacity also reaches 16G, 32G, 64G.Just some 500M, 1G are arrived in order, the RAM (random access memory) card of 2G backs off market gradually for this.People just seem awkward when in the face of multiple low capacity RAM (random access memory) card, directly abandon and seem a little unfortunate, even if but coordinate conventional card reader to use as USB flash disk one by one, do not store how many files again.
Summary of the invention
For solving the recycling problem of existing low capacity RAM (random access memory) card, the connection that the present invention proposes a kind of exented memory card holds card reader, and realize combining of multiple RAM (random access memory) card capacity to be extended to high capacity U disc, its technical scheme is as follows:
The connection of exented memory card holds a card reader, comprises the main body being provided with USB joint and multiple RAM (random access memory) card draw-in groove, this main body internal circuit board, and this circuit board is primarily of controlling and power module, module for reading and writing and the data bus composition being connected each RAM (random access memory) card draw-in groove; Described module for reading and writing detects, obtains the plug-in card capacity of each RAM (random access memory) card draw-in groove, and is each RAM (random access memory) card draw-in groove sequential addressing, and it is controlled by described control and power module; Described control and power module, by USB joint and host computer connecting communication, obtain electric energy by USB joint simultaneously.
In the middle of one or more embodiment of the present invention, described module for reading and writing obtains data by described control and power module, then carries out segmentation storage according to plug-in card capacity to data.
In the middle of one or more embodiment of the present invention, described control and power module are connected with a pilot lamp, are used to indicate energising and data transmission state that connection holds card reader.
The invention has the beneficial effects as follows: described module for reading and writing detects, obtains the plug-in card capacity of each RAM (random access memory) card draw-in groove, and be each RAM (random access memory) card draw-in groove sequential addressing, the capacity set of each RAM (random access memory) card is really accomplished to be combined, what user experienced on computer is a complete storer, instead of read and write multiple RAM (random access memory) card simply.The present invention solves the recycling problem of existing low capacity RAM (random access memory) card well, from its practicality and economy, is all the products with excellent performance.
Accompanying drawing explanation
Fig. 1 is the external structure schematic diagram of the connection appearance card reader of exented memory card of the present invention.
Fig. 2 is the principle framework schematic diagram of the connection appearance card reader of exented memory card of the present invention.
Embodiment
Following 1-2 by reference to the accompanying drawings, is further described the application's scheme:
A kind of connection of exented memory card holds card reader, comprise the main body 1 being provided with USB joint 2 and multiple RAM (random access memory) card draw-in groove 10, this main body 1 internal circuit board, this circuit board is primarily of controlling and power module 11, module for reading and writing 12 and the data bus composition being connected each RAM (random access memory) card draw-in groove; Described module for reading and writing 12 detects, obtain the plug-in card capacity of each RAM (random access memory) card draw-in groove, and is each RAM (random access memory) card draw-in groove sequential addressing, and it is controlled by described control and power module 12; Described control and power module 12, by USB joint 2 and host computer connecting communication, obtain electric energy by USB joint 2 simultaneously.
Described module for reading and writing 12 obtains data by described control and power module 11, then carries out segmentation storage according to plug-in card capacity to data.
Described control and power module 11 are connected with a pilot lamp 3, are used to indicate energising and data transmission state that connection holds card reader.
Above-mentioned preferred implementation should be considered as illustrating of the application's scheme implementation mode, allly to duplicate with the application's scheme, technology that is approximate or that make based on this is deduced, replaces, improvement etc., all should be considered as the protection domain of this patent.
