Battery voltage checking device
First Claim
1. A device to which a plurality of cases containing therein batteries capable of applying different nominal voltages are selectively mountable and which checks the battery voltage of a mounted case, comprising:
- signal means provided on at least one of said plurality of cases and emitting a discrimination signal to indicate which of said cases has been mounted;
voltage check means including a plurality of voltage check circuits corresponding to said cases to check each of the output voltages of the batteries contained in said plurality of cases; and
selector means operativey associated with said signal means during said mounting to select one of said plurality of voltage check circuits in accordance with said discrimination signal and apply to said selected voltage check circuit the output voltage of the battery contained in said mounted case as a voltage to be checked.
