Abstract
Disclosed is an improvement in a record player for turning the information stored on a cassette tape or a compact disc back into the original forms including a recording medium loading mechanism and an associated loading motor. It comprises means responsive to insertion of the recording medium for rotating the loading motor, thereby allowing it to generate the counter electromotive force, and a detection-switching device responsive to generation of the counter electromotive force for changing its conductive condition. Then, the loading motor is allowed to start and pull in the cassette or compact disk until it has been put in the loading position.
Claims6
A record player for turning information stored on a cassette tape or a compact disc back into original forms comprising a recording medium loading mechanism and an associated loading motor, wherein it further comprises means responsive to insertion of the recording medium for rotating the loading motor, thereby allowing it to generate a counter electromotive force, and a detection-switching device responsive to generation of the counter electromotive force for changing its conductive condition.
A record player for turning information stored on a cassette tape or a compact disc back into original forms comprising a recording medium loading mechanism and an associated loading motor, wherein it further comprises a gang of gears-and-slidable holder responsive to insertion of the recording medium for rotating the loading motor, thereby allowing it to generate a counter electromotive force;
- a detection switching transistor responsive to generation of the counter electromotive force for changing its conductive condition;
- and a system control computer connected to the detection switching transistor, the transistor having its collector electrode connected to a predetermined voltage source via an associated resistor, and its base electrode connected to the loading motor, thus allowing the loading motor to apply its counter electromotive force to the base electrode of the transistor, thereby changing its conductive condition.
