PURPOSE:To accurately operate an electronic circuit without erasing information stored in built-in memory even when abnormalities such as shortcircuiting of the output terminal of a packed battery or failure of apparatus in use occur. CONSTITUTION:The connection point of a current cut-off safety circuit 3 for avoiding abnormalities which is connected to a built-in battery 2 in series, is changed. The current cut-off safety circuit 3 is connected in series to the circuit to which an electronic circuit 4 and the built-in battery 2 are connected in parallel. Even when the power is cut off by the current cut-off safety circuit 3, power is supplied to the electronic circuit 4 from the built-in battery 2. Even when the current cut-off safety circuit 3 is cut off, a memory is reset and no information to be stored will be erased. |
