A facsimile device includes a main control unit and a sub-control unit. The first main control unit is configured to count a number of rings in a call signal sent from a public-line network and to put the facsimile device off-hook when the count value reaches a preset specified number of rings in the normal mode, and to suspend the count and off-hook functions in the energy-saving mode. The sub-control unit is configured to detect an incoming call signal and cause the main control unit to recover. The main control unit is configured to: calculate the number of rings in an incoming call signal in an elapsed time required from when the sub-control unit detects the incoming call signal until the main control unit recovers to the normal mode; and use the calculated number of rings to count the number of rings in an incoming call signal.
