Abstract
Abstract Disclosed is a structure of a housing for a paging receiver of the type including a storage device and a write terminal for a writing code in the storage device. A battery case is disposed in a part of the housing and provided with a window that communicates with the interior of the housing. The write terminal electrically connected to the storage device faces the window so that a connector of a writing apparatus may be inserted into the housing through the window to be connected to the write terminal. The write terminal is not exposed to the outside of the housing, thereby to enhance the resistivity to static electricity and hermetic sealing against dust, water and other impurities and therefore to achieve reliable operation.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
133 words
A housing structure for a paging receiver comprising: a printed-circuit board on which are mounted at least a storage device for storing code and a write terminal for writing the code in the storage device; a chamber for accommodating said printed-circuit board; a battery chamber that is spaced from the printedcircuit board chamber by an internal separating wall and that has an opening to permit battery insertion and removal from the outside; said internal separating wall having a window with an opening in said printed-circuit board chamber in proximity to the portion of said printed-circuit board on which said write terminal is mounted, and with a further opening in said battery chamber for allowing a connector of a writing apparatus to be inserted through the window and into contact with said write terminal.
Claim 2
Dependent Claim
