This invention relates to a wire-free sensing apparatus used in a disc system. The apparatus mainly comprises a beam emitting source installed at the case for emitting a beam, a reflector installed at the drawer for reflecting the beam, a beam receiving end installed at the case for receiving the beam reflected by the reflector, a switch installed at the drawer for controlling whether the reflector reflects the beam or not, and a one-way mirror installed at the case. The one-way mirror forms a non-right angle with an emitting direction of the beam and has a penetrating surface and a reflecting surface at opposite sides thereof wherein the beam penetrates the penetrating surface, and can be reflected by the reflector to the reflecting surface and then reflected by the reflecting surface to the beam receiving end.

We claim: 1. A wire-free sensing apparatus for a disc system, said disc system comprising a case and a drawer, said drawer being for adopting a data storage device and slidably received within said case, said wire-free sensing apparatus comprising: a beam emitting source, installed at a rear end of said case for emitting a beam; a reflector, installed at a front end of said drawer for reflecting said beam, and being movable to a straight emitting direction of said beam; a beam receiving end, installed at said case, being depart from said straight emitting direction of said beam for selectively receiving said beam reflected by said reflector; a switch, installed at said drawer for controlling whether said reflector reflects said beam or not, when said switch is at a KEY ON status, said reflector reflects said beam, and when said switch is at a KEY OFF status, said reflector does not reflects said beam; and a one-way mirror, installed at said case and positioned under said beam receiving end, and between said beam emitting source and said reflector, said one-way mirror forming an approximately 45 degree angle with the straight emitting direction of said beam, said one-way mirror comprising a penetrating surface at one side thereof facing said beam emitting source and a reflecting surface at the opposite side thereof facing said reflector, said penetrating surface being parallel to said reflecting surface; wherein when said switch at the KEY ON status, said beam penetrates said penetrating surface to said reflector, and is then reflected by said reflector in an opposite direction of said straight emitting direction of said beam to said reflecting surface and thereafter is perpendicularly deflected by said reflecting surface to said beam receiving end; whereby said disc system can judge whether said drawer is properly received within said case in determining whether said beam receiving end receives said beam. 2. The wire-free sensing apparatus of claim 1, wherein said beam emitting source is a light emitting diode (LED). 3. The wire-free sensing apparatus of claim 1, wherein said beam emitting source is a laser emitter. 4. The wire-free sensing apparatus of claim 1, wherein said beam emitting source is an infrared ray emitter. 5. The wire-free sensing apparatus of claim 1 further comprising a light-guiding pipe installed at said drawer for guiding said beam emitted from said beam emitting source to said reflector. 6. The wire-free sensing apparatus of claim 5 wherein said light-guiding pipe is a winding light-guiding pipe for being adapted to the location of said reflector. 7. The wire-free sensing apparatus of claim 5 wherein said light-guiding pipe is made of glass fiber. 8. The wire-free sensing apparatus of claim 5 wherein said light-guiding pipe is made of acrylics. 9. The wire-free sensing apparatus of claim 5 wherein said beam receiving end sends a message to a data processing device informing said data processing device whether said drawer is properly received within said case so that said data processing device can timely save un-saved data to said data storage device in said drawer. 10. The wire-free sensing apparatus of claim 9 wherein said data processing device is a computer. 11. The wire-free sensing apparatus of claim 9 wherein said data processing device is a server. 12. The wire-free sensing apparatus of claim 1 wherein when said beam receiving end receives said beam, said drawer is judged as being properly received within said case. 13. The wire-free sensing apparatus of claim 1 wherein when said beam receiving end does not receive said beam, said drawer is judged as being properly received within said case.
