Description

1373782 v IX. Description of the Invention: [Technical Field] The present invention relates to a positioning mechanism and an external keyboard having the same. [Prior Art] With the rapid development of the communication industry, the use of various portable electronic devices such as mobile phones and personal digital assistants (PDAs) has become more and more popular. At the same time, more and more consumers are no longer satisfied with the simple answering phone function of the 亥▼-type electronic device. They hope that the portable electronic device has multi-function, convenient use and fast key input. However, the conventional portable electronic device is short, small, light, and thin due to its own size. The limitation makes the conventional portable electronic device keyboard have great defects in the game and the fast input operation, which brings great inconvenience to the user. In view of the above defects, some manufacturers in the market have introduced external portable electronic devices. On the mini keyboard. The external type of mini-keyboard ♦ button layout is basically the same as that of a normal computer keyboard. The eight are interconnected with a portable electronic device by a universal serial bus (USB) or Bluetooth. The user can operate the external keyboard of the external device with both hands to greatly improve the speed of the game operation and the information input operation during use. The mini keyboard is placed on the surface of the button of the portable electronic device. If there is only a mini keyboard and no corresponding positioning mechanism, the keyboard 5 is on the surface of the button of the portable electronic device, and the mini keyboard 5 is tilted or even dropped on the surface of the button due to uneven force during use. The separation of the τ-type electronic device brings a lot of inconvenience to the use. 7 1373782 SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a positioning mechanism that can be used to position a component to be positioned on a device to achieve its positioning and holding functions.
