Abstract
The invention relates to battery-operated appliances, and to an improved battery storage compartment. The battery (47, FIG. 7) lies in a compartment in a housing (20), the housing having a front face containing controls (28, 30) and a display (26). An aperture (44) lies in the housing front face to enable battery replacement from the front, and a cover (110) covers the aperture. The cover has ports (124) through which plugs (122) pass to reach sockets (32). A circuit board (36, FIGS. 3 and 4) lies behind the rear wall (134) of the battery compartment, the circuit board having about as great a width and length as the housing.
