Abstract

The present invention relates to a portable terminal device, such as a cellular phone, which has a screen display section, such as an LCD module, in its upper part and a key manipulation section having an array of plural keys in its lower part. The portable terminal device has a removable battery and is highly protected from water especially in a battery area. There is provided a pair of inner housings, that are a backside inner housing and a front side inner housing, which form a battery compartment having an opening for battery insertion / removal. A key manipulation sheet is disposed on the front side inner housing, and the whole components are covered with a pair of outer housings.

Description

[0001] This application is a continuation of U.S. Ser. No. 10 / 765,221 filed Jan. 28, 2004.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a portable terminal device, such as a cellular phone, which has a block-like screen display section, such as an LCD module, in its upper part and a sheet-like key manipulation section having an array of plural keys in its lower part. [0004] 2. Description of the Related Art [0005] In recent years, portable terminal devices including cellular phones have become widely used. Some of these portable terminal devices have various additional capabilities, for example, are made waterproof. [0006] In conventional waterproof portable terminal devices, a battery pack is located externally, and a cover is placed over the battery that is once mounted. Such a configuration requires a large-area and large-scale mechanism to hold the battery pack, protect it from water and hermetically seal in it, resulting in...
