Facsimile Device Performing Off-Hook in Preset Specified Number of Rings without Ring Apparatus

A facsimile device, comprising:

• a main control unit including a second main control unit having a normal mode and an energy-saving mode, the second main control unit being 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;
• a sub-control unit configured to detect an incoming call signal when the main control unit is in the energy-saving mode, and cause the main control unit to recover to the normal mode;
• and
• a storage unit configured to store a number of rings of call signal in a predetermined elapsed time required until recovery to the normal mode;
• wherein
• the main control unit is configured to count the number of rings of call signal based on the number of rings stored in the storage unit after recovery to the normal mode.

A facsimile device, comprising:

• a main control unit including a third main control unit having a normal mode and an energy-saving mode, the third main control unit being configured to measure a predetermined time and to put the facsimile device off-hook when the measured time reaches a required time in the normal mode, and to suspend the count and off-hook functions in the energy-saving mode;
• a sub-control unit configured to detect an incoming call signal when the main control unit is in the energy-saving mode, and cause the main control unit to recover to the normal mode;
• and
• a storage unit configured to store the required time required until a number of rings of call signal reaches a preset specified number of rings after the call signal arrives;
• wherein
• the main control unit is configured to measure, after recovery to the normal mode, the required time based on elapsed time required until the main control unit recovers to the normal mode after the sub-control unit detects a call signal.
