## Background
BACKGROUND
1. Technical Field
The present disclosure relates to a portable storage device, and more particularly to a portable storage device with individual processing functions.
2. Description of Related Art
Portable storage devices, such as cards or external hard drives, are often used for storing data and transmitting data among different electronic devices. However, data access between portable storage devices and a host device, such as a computer, is usually controlled by the host but not by the portable storage devices, such that data stored on the device cannot be managed by the portable storage itself when it is not connected to a host. Thus, convenience for the user is affected.



BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1A is a view of one embodiment of a portable storage device.
FIG. 1B is another view of one embodiment of the portable storage device.
FIG. 2 is a block diagram of one embodiment of the portable storage device.



DETAILED DESCRIPTION
FIG. 1A and FIG. 1B are two views of one embodiment of a portable storage device 100.
The portable storage device 100 includes a case 10, a USB plug 20, a slide button 30, a delete button 40, a controller 50 and a memory module 60. The case 10 includes a first surface 11, a second surface 12 opposite to the first surface 11 and a terminal portion 13 disposed between the first surface 11 and the second surface 12.
In one embodiment, the first surface 11 comprises a slide slot 111. A display 121 is disposed in the second surface 12. An opening 131 is disposed in the terminal portion 13, and the opening 131 is through the slide slot 111. The USB plug 20 can be housing in the case 10 through the opening 131. The slide button 30 is round, with a receiving portion is disposed in one terminal of the slide button 30. The slide button 30 can be received in the slide slot 111 and be fixed with the USB plug 20. When the slide button 30 moves along the slide slot 111, the slide button 30 carries the USB plug 20 to slide in the case 10. Thus, the USB plug 20 can extend out of the case 10 or be housed in the case 10 according to the movement of the slide button 30. When the slide button 30 slides to one terminal of the slide slot 111 near the opening 131, the USB plug 20 extends out of the case 10 from the opening 131. When the slide button 30 slides to the other terminal of the slide slot 111 away from the opening 131, the USB plug 20 is completely housed in the case 10. The delete button 40 is disposed in the terminal of the slide slot 111 away from the opening 131. When the slide button 30 slides to the terminal of the slide slot 111 away from the opening 131, the USB plug 20 is completely housed in the case 10. A containing portion 31 is disposed in one terminal of the slide button 30. The delete button 40 is housed in the containing portion 31 when the slide button 30 slides to the terminal of the slide slot 111 away from the opening 131.
FIG.2 is a block diagram of one embodiment of the portable storage device. The portable storage device includes the controller 50 and the memory module 60, both disposed in the case 10. The controller 50 is electrically coupled to the USB plug 20, the display 121, the delete button 40 and the memory module 60. When the USB plug 20 is electrically coupled with a electronic device, the controller 50 controls the memory module 60 to transmit or store data to electronic device, whereby the electronic device can access data or store data from the memory module 60. Moreover, the controller 50 is capable of displaying content information on the display 121. In one embodiment, the content information includes total storage capability info, used volume or the type of stored data. In addition, the controller 50 allows direct deletion of data stored in the memory module 60 via the delete button 40 with no requirement for a host device defined in USB specification, such as a computer, so that user can delete data stored in the portable storage device 100 by pushing the delete button 40 directly.
In one embodiment, data stored in the memory module 60 of the portable storage device 100 can be deleted by pushing the delete button 40 without any host device such as computer. The USB plug 20 can be housed in the case 10. Moreover, the delete button 40 can be housed in the slide button 30 so as to avoid possibility of mistakenly deleting data. In addition, information about the data stored in the memory module 60 can be shown in the display 121.
Although certain inventive embodiments of the present disclosure have been specifically described, the present disclosure is not to be construed as being limited thereto. Various changes or modifications may be made to the present disclosure without departing from the scope and spirit of the present disclosure.

## Claims

1. A portable storage device, comprising:
a case;
a USB plug;
a storage, storing data transmitted through the USB plug; and
a controller, electrically coupled to the USB plug and the storage, and controlling data accessed through the USB plug; and
