Abstract
A recording-medium holder insertion detection apparatus includes a motor which is engaged with the recording-medium holder placed at a first position within a recording/reproducing system, the motor moving the holder in an insertion direction from the first position when the motor is rotated by a drive voltage, and the motor generating an alternating voltage when the motor is rotated by a manual insertion of the holder so as to reach a second position. A detection circuit outputs a pulsed signal in response to the alternating voltage generated by the motor. A determination unit calculates a distance of the holder away from the first position in the insertion direction based on the pulsed signal output by the detection circuit, and outputs a drive-start signal when the calculated distance has reached a predetermined distance between the first position and the second position.
