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.
