ップ制御回路7の出力は制御対象回路に供給される。The positive side of the battery 1 is a positive side power contact pin 2 and a battery pack attachment / detachment detection pin 4 having a short effective mating length.
The negative side of the battery 1 is connected to the negative side power contact pin 3 to form a battery pack. Next, the main body side of the information equipment is supplied with the positive side power source by the positive side power source contact pin 2 and the negative side power source by the negative side power source contact pin 3, and the battery pack attachment / detachment detection pin 3 is connected to one end of the resistor 5 and the buffer. The input of the circuit 6 is connected, the other end of the resistor 5 is connected to the negative power source, the output signal of the buffer circuit 6 is supplied to the backup control circuit 7, and the output of the backup control circuit 7 is supplied to the controlled circuit. .

作中の回路動作は保証される。Next, when the operator tries to pull out the battery pack, the positive side power supply contact pin 2 and the negative side power supply contact pin 3 are separated because the battery pack attachment / detachment detection pin 4 has a short effective fitting length. Before being removed, the battery pack attachment / detachment detection pin 4 becomes unconnected, the voltage drop across the resistor 5 becomes zero, the input of the buffer circuit 6 becomes low level, and the buffer circuit 6
Becomes a low level, and the backup control circuit 7 instructs the control target circuit to perform a backup operation according to this signal state. At this time, since the plus side power source contact pin 2 and the minus side power source contact pin 3 are not disconnected, the power source voltage from the battery 1 is completely supplied and the circuit operation during the backup operation is guaranteed.
