Description
Technical field
The present invention relates to the method for a kind of card reader and its data transmission, refer to a kind of especially through the card reader that has simple structure after integrating and its data transmission method to memory card.
Background technology
Now on the market popular card reader be divided into and be internal connecting type card reader and circumscribed card reader.Yet, no matter be internal connecting type or circumscribed, on the size of the simplification of its structure or volume, all be very important.Designs simplification or volume-diminished the consumer be installed on the general personal computer or at mobile computer go out carry, all be to be particular about very much; On the other hand, reduced volume also can reduce the cost of manufacturer.Therefore, all brought under the condition of benefit on both side giving, towards light, thin, short, little development, be more and more tangible trend with the structure of card reader or volume; Even, also upwards development constantly in the breakthrough of technology.
With regard to the structure of general known technology, please refer to shown in Figure 1ly, be known card reader structural representation.This card reader comprises a data input output interface 11 ', and this data input output interface 11 ' is taked the form of USB; One management system 13 ' comprises a control module 131 ', a mnemon 133 ', a processing unit 135 '; One data fetcher 15 ', comprise a Compact Flash card reading device 151 ', a Memory Stick card reading device 153 ', a Smart Media card reading device 155 ', a SecureDigital card reading device 157 ', this data fetcher 15 ' is generally taked two kinds of aspect supply the markets, and promptly a slot can read multiple different memory card and reads different memory cards respectively with many slots; Wherein, corresponding with it the respectively memory card of each reading device reads control with access with two kinds of communication interfaces, as this Compact Flash card reading device 151 ' see through a data transmission interface 1511 ' with eight terminals with a control interface 1513 ' and and a Compact Flash card 171 ' binding; This Memory Stick card reading device 153 ' see through a data transmission interface 1531 ' with four terminals with a control interface 1533 ' and and a Memory Stick card 173 ' binding; This Smart.Media card reading device 155 ' see through a data transmission interface 1551 ' with eight terminals with a control interface 1553 ' and and a SmartMedia card 175 ' binding; This Secure Digital/Multi-media card reading device 157 ' see through a data transmission interface 1571 ' with four terminals with a control interface 1573 ' and and a SecureDigital/Multi-media card 177 ' binding.Wherein, a plurality of terminals that each data transmission interface had often cause the increase on structural complicated and the cost, shown in scheming, have 24 terminals altogether and carry out the transmission of data, increase many costs; More therefore, if there is any terminal to produce problems such as distortion, and the aspect that is cooperated is again the card reader that belongs to All-in-One, certainly will this card reader must be time-consuming, take cost and keep in repair, even whole card reader scrapped.
Based on the generation of above-mentioned these situations, the card reader inner structure is carried out again layout and improvement, be the problem of required positive discussion at present.
Summary of the invention
The technical problem to be solved in the present invention is: a kind of modified card reader is provided, to simplify its inner structure, makes card reader reduce the probability of fault, reduce the cost of its maintenance during with fault.
Another technical matters that the present invention will solve is: a kind of modified card reader is provided, to dwindle the volume of card reader, when making it be assemblied in general personal computer, dwindles shared space as far as possible; On the other hand, if when being disposed at mobile computer, be convenient for carrying.
The technical matters again that the present invention will solve is: a kind of modified card reader is provided, reduce production costs with the structure of simplifying, therefore can be widely used in the built-in equipment of desktop PC, free-standing USB card reader, the built-in card reader of mobile computer, the built-in USB card reader of printer, the built-in USB card reader of household appliances, electronic photo album, the built-in card reader of portable product, mobile phone etc.
The another technical matters that the present invention will solve is: provide a kind of modified card reader data transmission method, with the structure of its conformability and unique data transfer path, merely and carry out the transmission of data apace.
For this reason, the present invention proposes a kind of modified card reader, comprising: a data input output interface, and the funding material passes in and out this card reader; One management system, the turnover of control and managerial data; At least one data fetcher, make at least a memory storage can with its binding, to carry out the access control of data for this memory storage of turnover; At least one data is shared control device, when data turnover memory storage, and the path of the access of giving information; When data input output interface and calculator system binding, and when memory storage and data fetcher, data are shared the control device binding, the cooperate with each other data of detecting, control turnover memory storage of this management system and this calculator system, and the data of this turnover is passed in and out by the path that the shared control device of this data is provided.
The present invention also proposes a kind of method of modified card reader data transmission, comprising:
(1) beginning;
(2) initialization one card reader;
(3) this card reader and a memory storage are linked;
(4) this memory storage of interpretation, and carry out the control of data turnover memory storage and unique transmission of data turnover memory storage respectively;
(5) finish.
Characteristics of the present invention and advantage are: the method for modified card reader of the present invention and its data transmission, when data input output interface and calculator system binding, and when memory storage and data fetcher, data are shared the control device binding, the cooperate with each other data of detecting, control turnover memory storage of this management system and this calculator system, the data of turnover is shared the path turnover that control device is provided by data.The present invention is through the structure after integrating, and is more simple than known technology, to dwindle the volume of card reader, when making it be assemblied in general personal computer, dwindles shared space as far as possible; On the other hand,, be convenient for carrying, on maintenance and cost, can save many if when being disposed at mobile computer; Simultaneously, simple property and agility in the time of on data transmission, more can guaranteeing to transmit.
