Abstract

The invention discloses a portable electronic device, which provides an electronic device capable of being connected to a storage medium through the portable electronic device. The portable electronicdevice comprises a first transmission interface, a second transmission interface and a selection interface. The first transmission interface is used to be electrically inserted into by the storage medium so as to build data which is transmitted on the portable electronic device; the second transmission interface is used for the electronic device to build data which is transmitted on the portableelectronic device; and the selection interface is operationally connected to the first and second transmission interfaces so as to switch the electronic device to write-only, read-only or read-write in the storage medium.

Description

Technical field [0001] The invention relates to a portable electronic device. Background technique [0002] With the development of technology, portable electronic devices are becoming more and more common. For example, notebook computers, personal digital assistants, mobile communication devices and mobile storage devices have become indispensable daily necessities in life. These portable electronic devices all have the function of data transmission (including data reception, data storage or data transmission), and there are still dangers and inconveniences in the technology of data transmission. [0003] Known portable electronic devices often need to be used as relay devices for data transmission. For example, mobile phones are equipped with a memory card interface and a universal serial bus (USB) interface, which can accommodate a memory card and connect to a laptop computer, and the mobile phone As a relay device for data transmission between memory cards and notebook compute...
