Description
Technical field
The utility model relates to CF (Compact Flash) storage card, specifically is the CF card that can directly be connected and carry out the data transmission with PC about a kind of.
Background technology
In recent years because the making rapid progress of electronics technology, the performance of computer and peripheral product thereof improves constantly, various software is also constantly weeded out the old and bring forth the new thereupon, and cheaper price, it is universal day by day to make computer and peripheral product thereof be able in our routine work, study, life, and people to the demand of computer also thereby be able to quick growth, the manufacturer of each big computer and peripheral product thereof, in the face of this vast and emerging consumption market, wholeheartedly strive for invariably.
At present, the most extensive image capture unit that is used, as digital camera, provide a CF card (storage card) on it, make the digital camera can be with institute's picked image, convert digital signal to, be stored in this CF card, make this CF card and PC (PC) when being connected, this signal of video signal can be transferred to PC (PC), still, this CF card is changed without interface (as PCMCIA Converter, Card Reader), promptly can't directly be connected, therefore cause usability and the popularization that has limited this CF card with PC (PC).
Summary of the invention
In view of this, commonly use the shortcoming that the CF card can't directly be connected with PC for overcoming, the utility model provides a kind of CF card that can directly be connected and carry out the data transmission with PC, its objective is and on the CF card, be provided with a sequence transmission interface, make this CF card except can being used in electronic installation (as: digital camera), also can directly be connected, and stored data is transferred to PC, perhaps with data storage that PC transmitted by sequence transmission interface with PC.
The technical solution of the utility model is achieved in that
A kind of CF card that can directly be connected and carry out the data transmission with PC comprises:
One CF interface;
One sequence transmission interface can directly be connected with the sequence transmission interface of PC (PC) by a transmission line, makes this CF card with stored data, transfers to PC (PC), or the data storage that PC (PC) is transmitted.
A kind of CF card that can directly be connected and carry out the data transmission with PC, when the CF card is connected with PC, the CPU (central processing unit) of this PC will detect with the CF card and be connected, and out-put supply is to the CF card, required electric power for should the start of CF card the time, then, stick into the transmission of capable data again by sequence transmission interface and this CF.
CF card of the present utility model is provided with a sequence transmission interface, can directly be connected and carry out the transmission of data with PC, and can be connected with electronic installation again and carry out data transmission, has very obvious effect.

Embodiment
Below enumerate embodiment, and in conjunction with the accompanying drawings,, be described in further detail the purpose of this utility model, shape, constructing apparatus feature and effect thereof.
The utility model is a kind of " can directly be connected and carry out the CF card of data transmission with PC ", see also shown in Figure 1, this CF card 11 is provided with a CF interface 13 and a sequence transmission (USB) interface 15, the sequence transmission interface 15 of this CF card 11 can directly be connected with the sequence transmission interface 23 of PC 21 (PC) by a transmission line 16, and with stored data, transfer to PC 21 (PC), or the data storage that PC 21 (PC) is transmitted.
In the utility model, see also shown in Figure 2ly, when CF card 11 is connected with PC 21, the CPU (central processing unit) of this PC 21 will be handled according to the following step:
(201) detect with CF card 11 and be connected;
(202) out-put supply is to CF card 11, required electric power for should 11 starts of CF card the time;
(203) carry out the data transmission by sequence transmission interface 15 and this CF card 11.
In the utility model, see also shown in Figure 3, the CF interface 13 of this CF card 11 can be connected by the CF interface 33 of transmission line 16 with electronic installation 31 (as digital camera, notebook computer, palmtop computer, PC or card reader etc.), and accept the access command of electronic installation 31, with stored data, transfer to electronic installation 31, or the data storage that electronic installation 31 is transmitted.
In the utility model, see also shown in Figure 4ly, when CF card 11 is connected with electronic installation 31, the microprocessor of this electronic installation 31 will be handled according to the following step:
(401) detect with CF card 11 and be connected;
(402) out-put supply is to CF card 11, required electric power for should 11 starts of CF card the time;
(403) electronic installation 31 passes through CF interface 13,33 with CF card 11, carries out the data transmission.
In the utility model, see also shown in Figure 5ly, this CF interface 13 is located on CF card 11 1 sides, and sequence transmission interface 15 then is located on CF card 11 another sides.
So, the CF card also can be connected the transmission of carrying out data at any time with PC except being used in electronic installation.
The above, only be best specific embodiment of the present utility model, but feature of the present utility model is not limited thereto, anyly is familiar with this skill person in this creation field, can think easily and variation or modification, all should be encompassed within the claim scope of this case.
