Abstract
The utility model relates to a USB interface accessing device capable of switching mode, which is provided with a USB interface unit which can be used for connecting an electronic device, a USB controller which can be used for controlling a functional module set, and a manual diverter switch which is connected with the USB controller, wherein the USB controller is connected with the USB interface unit. The master mode or the slave mode can be switched by using the manual diverter switch, and the USB controller is arranged to perform a master mode driving program or a slave mode driving program.
Description
Technical field
The utility model is about a kind of access device, refers to a kind of USB interface access device of changeable pattern especially.
Background technology
With the progress day by day of work science and technology, (for example: digital camera, MP3, PDA etc.) external form is more and more lighter and handier, and the processing capacity of numerical data is also more and more stronger for portable apparatus.Generally, between portable apparatus or computer apparatus, make data transmission or store data by network or disk, but problem because of storage volume and portability, so present mobile access device (for example carry-on dish) comes the access data to replace disk gradually, and can insert another electronic installation by carry-on dish, to carry out the data transmission.
At present with oneself dish is generally to utilize the USB interface as transmission interface, in addition, with USB wiring series connection digital camera and computer, and opens the power supply of camera, just can be fast and easily the image of digital camera is transferred to computer, and conveniently inspect, compile or print.And the USB interface that at present carry-on dish and digital camera are adopted is to be redefined for subordinate pattern (Slave mode), for example then be set at aggressive mode (Mastermode) for the USB interface that electronic installation adopted of PC, therefore this predefined pattern makes the not enough elasticity of use of USB interface the USB interface access device that needs design one changeable pattern to strengthen the elasticity of its use.
The utility model content
Fundamental purpose of the present utility model is to provide a kind of USB interface access device of changeable pattern, and can make access device changeable is active (Master) pattern or subordinate (Slave) pattern.
For achieving the above object, the USB interface access device of the changeable pattern that the utility model provides comprises:
One USB interface unit is for being connected with an electronic installation;
One USB controller supply to be connected with a functional module group, and this USB controller is connected to this USB interface unit; And
One manual change-over switch, be connected in this USB controller, in order to switch this USB controller is aggressive mode or subordinate pattern, and when this Manual Transfer Switch switches to the moving pattern of king, set this USB controller and carry out an aggressive mode driver, and when this Manual Transfer Switch switches to the subordinate pattern, set this USB controller and carry out a subordinate mode activated program.
Wherein this Manual Transfer Switch can be set at ' 0 ' and reach ' 1 ' two states.
Wherein when the state of Manual Transfer Switch was ' 0 ', pattern belonged to the subordinate pattern and starts subordinate mode activated program.
Wherein when the state of Manual Transfer Switch was ' 1 ', pattern belonged to aggressive mode and starts the aggressive mode driver.
Wherein this functional module group can be a reservoir.
Wherein this electronic installation is a digital camera.
Wherein this electronic installation is a printer.
Wherein this electronic installation is a mobile phone.
Description of drawings
Fig. 1 is the functional block diagram of the USB interface access device of the changeable pattern of the utility model.
Fig. 2 is the mode initialization flow process of the USB interface access device of the changeable pattern of the utility model.
Embodiment
The USB interface access device preferred embodiment of relevant changeable pattern of the present utility model, please be with reference to the functional block diagram of Fig. 1 demonstration, its show this access device 1 mainly by USB interface unit 2, functional module group 3, USB controller 4, and main member such as Manual Transfer Switch 5 formed, the aforementioned functional module can be a reservoir.
Aforesaid USB interface unit 2 is in order to connect an electronic installation 6, and in present embodiment, electronic installation 6 can be printer, computer apparatus, mobile phone or digital camera etc.Wherein, USB interface unit 2 can be a USB connector.USB controller 4 is connected with functional module group 3 and USB interface unit 2 respectively, and 5 of Manual Transfer Switch are connected with USB controller 4, come switch mode in order to Manual Transfer Switch 5.
Manual Transfer Switch 5 is used for switching USB controller 4 and is aggressive mode or subordinate pattern, when this when moving change-over switch 5 switches to aggressive mode, set this USB controller 4 and carry out an aggressive mode driver, and when this Manual Transfer Switch 5 switches to the subordinate pattern, set this USB controller 4 and carry out a subordinate mode activated program.
And please refer to the process flow diagram of switching mode shown in Figure 2.When if the state of the Manual Transfer Switch of access device is ' 0 ', then pattern belongs to the subordinate pattern and starts subordinate mode activated program; Otherwise the state of the Manual Transfer Switch of access device is ' 1 ', and pattern belongs to aggressive mode and start the aggressive mode driver.
By above explanation as can be known, the utility model utilizes a manual change-over switch 5 to set USB interface access device to be aggressive mode or subordinate pattern, when being aggressive mode, set the USB controller and carry out an aggressive mode driver, and when for the subordinate pattern, set the USB controller and carry out a subordinate mode activated program,, and can make the use of USB interface not be subjected to any restriction so that USB interface access device can be set at aggressive mode or subordinate pattern.
Only for convenience of description and for example and own, the interest field that the utility model is advocated should be as the criterion so that claim is described the foregoing description certainly, but not only limits to the foregoing description.
