ABSTRACT:
A small-sized electronic apparatus having one or more replaceable batteries housed in a battery compartment of the body of the apparatus, wherein the apparatus comprises: a cover which is moved to open or close the battery compartment; a switching member for switching on and off the power source; and a linking member to which the switching member is attached and which is moved with the movement of the cover to allow the switching member to turn off the power source when the cover is moved to open the battery compartment, whereby the power is automatically turned off when the cover for the battery compartment is opened, so that there is no possibility of the stored data being lost or distorted even if the user tries to replace the battery without turning off the power switch.
