To surely prevent a normal mode from being restored from an energy saving mode by off-hook.SOLUTION: The ringer interrupt control unit 44 outputs the ringer interrupt signal S2 according to the ringer detection signal S1 when the off-hook detection signal S3 is not output (that is, in a state where the receiver of the external telephone 37 is put down), so that the mode control unit maintains the energy saving mode and does not switch to the normal mode even when the receiver of the external telephone is lifted and the off-hook signal is output (that is, even when the off-hook detection signal is output) in the energy saving mode. As a result, the mode control unit does not switch from the energy saving mode to the normal mode only by lifting the receiver of the external telephone, thereby preventing a decrease in energy saving efficiency.SELECTED DRAWING: Figure 2
