An electric arm lifting and turntable's auto-stop assembly of a record player is revealed. A record player is disposed with a power-driven turntable, a rotatable and movable arm disposed on one side of the turntable, a lift mechanism used for pushing against and moving the arm upward, and a sensor. The arm is moveable over the turntable. The sensor is arranged at an arm rotating shaft of the arm and used for sending a signal while detecting that the arm is moved to a lift point over the turntable. The lift mechanism is activated to move the arm upward and the turntable is stopped simultaneously for protecting a needle on the arm while the sensor detects that the arm has been moved from the turntable to the lift point.
