Abstract

Provided is an input / output (I / O) expansion device for a portable electronic apparatus having a port to which an external expansion device can be connected. The I / O expansion device includes: a display body having at least one display portion; and at least one I / O connector formed at a portion of the display body to be electrically and physically attached to and separated from the port of the portable electronic apparatus. Therefore, it is possible to provide a multi-function I / O expansion device that can be electrically and physically attached and separated.

Description

technical field [0001] The present invention relates to an input / output (I / O) expansion device for a portable electronic device, and more particularly, to a display unit capable of expanding a conventional portable electronic device by attaching a short-distance information recognition and transfer device, a biosensor, etc. and An I / O expansion unit for portable electronic devices that also adds functionality. Background technique [0002] With the development of the information and communication industry, an initial cellular phone only for voice communication is developing into an integrated device having functions of a digital camera, a Moving Picture Experts Group (MPEG) Layer 3 (MP3) player, and the like. Recently, various optional electronic devices such as sensors having various functions, information storage devices, etc. are integrated in such mobile devices, and thus the functions of the mobile devices are diversified. However, an appropriate power source is requir...
