<p>PROBLEM TO BE SOLVED: To provide a miniature and inexpensive loading device in which no micro switch is used for detecting the insertion of a recording medium into a main body. SOLUTION: A gear 11 is rotated by a tray 20 inserted into a port 13, and by linking with the rotation of this gear 11, a rotary shaft of a DC motor 10 is rotated. At that time, the electromagnetic induction is generated inside the motor, and the voltage corresponding to this electromagnetic induction is produced in a power supply line. A control part 2 judges whether the tray 20 is inserted into the main body from the port 13 or not in accordance with whether the voltage is produced in the power supply line or not, then the tray 20 inserted into the port 13 is transported to the processing position.</p> |
