Portable electronic apparatus having external connector fixed at internal circuit board

1. Field of the Invention A portable electronic apparatus includes: a box-type case having an opening at its rear face and upper face; a circuit board having a receiving portion and an engaging hole formed adjacent to the receiving portion, the circuit board being installed inside the case; a key board unit positioned at an upper surface of the case; and a connector having a front face with a plug inserting portion, a side face having a fixing piece and a lower face, wherein the lower face of the connector penetrates the receiving portion and is fixed at the circuit board, and the plug inserting portion of the connector faces the opening. Since the connector is positioned penetrating the receiving portion formed at the circuit board, the connector may be positioned at about the middle position of the connector, to make the whole product thin. In addition, in case where a flexible printed circuit is used to connect the connector and the circuit board, the plurality of terminals included in the connector can be connected simply with the circuit board and interference with other components can be minimized.
