<p>PURPOSE:To eliminate the restriction of external and internal construction caused by battery chamber and to improve the use on human engineering, and to obtain thin and small sized unit, by separating the battery chamber of electronic unit from the external package and forming it as a single component. CONSTITUTION:The battery chamber 4 which had been formed unifiedly with the external package upper case 1 or lower case 2 conventionally, is separated from the external package and constituted as independent component, and it can be located at the position entirely independently of the dismounting direction of the mold of the external package upper and lower cases 1, 2, and the external construction can accept the request on the desing such that the slope advantageous to human engineering is provided for the operation section 7 as shown in Figure. Further, as to the internal construction, the internal components can be located so that unnecessary space can be avoided, allowing to make thin and small for the entire construction.</p> |
