Abstract
A slim-type optical disc drive includes a casing and a tray. A first circuit board is disposed within the casing. A second circuit board is disposed on the tray. A spring switch is disposed on the second circuit board. A first end of the spring switch is fixed on the second circuit board. A resistor is connected between the first end of the spring switch and a first power source. A second end of the spring switch is extended outside the second circuit board. In a tray-out status, the second end of the spring switch is not contacted with any object, so that a first status signal is generated. In a tray-in status, the second end of the spring switch is contacted with a conducting zone of a second power source, so that a second status signal is generated.
