This invention is about an automatic recording/playing device and the method, an apparatus for recorder having sensor and method for playing/recording using the same, which is linked to the independent telephone line and is put somewhere in the user's room, receives and stores appropriate voice data which are sent by the main computer at the information provider's head office through the telephone line, plays back the stored voice data at the set time by the user and when the user comes near/into the area of motion sensor(infrared sensor) which is attached to the invention, or when the light sensor works which is also attached to the invention at the time the user turns off the light to sleep at night. All these operations take place automatically. So the user need do any action to work the invention and t listen to the recorded voice data, making the user a foreign language more effectively and steadily. The invention includes DTMF receiver and line controller unit (which receives DTMF signals through the telephone line, changes them into digital signals, and sends them to the voice recorder as the control of the main control unit), sensor unit (which senses the movement of the user and the change of the light), memory unit (which tells the time and place of the stored voice data recorder in the voice recorder), voice recorder unit (which plays back the recorded voice data through the speaker or sends out the recorded voice data through the spare output unit to the other devices) , input key unit (which receives and sends the user's orders to the main control unit in order to play back, delete, scan the recorded voice data or to adjust the current time, the playing back time, or the operation time of the sensors), and the main control unit ( which receives the DTMF signals sent from the DTMF receiver and line control unit, makes the on/off hook switch of the telephone unit hooked off to make the appropriate signals received and recorded automatically, stops the recording work when the arranged time passes or when the arranged DTMF stop signals are received or when the voice data receiving work doesn't occur for over a certain period of time.)
