Abstract
An image forming apparatus and a telephone operation regulating method thereof, the image forming apparatus including a main body that is connectable to an external telephone communication line; a receiver comprising an audio output unit and an audio input unit, connected to the main body; and a sensing unit disposed inside the receiver, to determine whether the receiver is in an on-hook state or an off-hook state.
Claims15
An image forming apparatus, comprising:
- a main body that is connectable to an external telephone communication line;
- a receiver comprising an audio output unit and an audio input unit, connected to the main body through a telephone line;
- and
- a sensing unit disposed inside the receiver, to output a sensing signal to the main body, according to whether the receiver is in an on-hook state or an off-hook state.
A telephone operation regulating method of an image forming apparatus that comprises a main body and a receiver comprising an audio output unit and an audio input unit, the method comprising:
- transmitting a first sensing signal to the main body, using power supplied to the receiver to drive at least one of the audio output unit and the audio input unit, if the receiver is in an off-hook state;
- turning on a telephone operation of the image forming apparatus, according to the first sensing signal;
- transmitting a second sensing signal to the main body using the power, if the receiver is in an on-hook state;
- and
- turning off the telephone operation of the image forming apparatus, according to the second sensing signal.
An image forming apparatus, comprising:
- a main body that is connectable to an external telephone communication line;
- a receiver comprising an audio output unit and an audio input unit, connected to the main body through a telephone line;
- an electric power supply unit to supply a driving voltage to the receiver, to drive the audio output unit and/or the audio input unit;
- a sensing unit disposed inside the receiver, to output a sensing signal to the receiver, according to whether the receiver is in an on-hook state or an off-hook state, using the driving voltage or a ground voltage applied to the receiver;
- and
- a control unit to determine whether the receiver is in the on-hook state or off-hook state, based on the sensing signal.
