Patent ID: 8042127

Claim:
An optical disk player capable of monitoring the optical disk status comprising: a shell ( 1 ), a plummer ( 12 ) fixed in the shell, a transport mechanism for transporting the optical disk between the optical disk insertion inlet ( 5 ) and the plummer ( 12 ), a guiding mechanism for guiding the optical disk to the center of the transport path, an optical disk loading final position detection mechanism, and a control part ( 40 ) for controlling a chuck plate ( 22 ) to keep the optical disk on the plummer ( 12 ) and canceling the holding of the transport mechanism to the optical disk when an optical disk being transported to be above the plummer, characterized in that: the shell ( 1 ) is composed of an upper base plate ( 2 ) and a lower base plate ( 3 ), and a clearance ( 4 ) used as the optical disk transport path is located between the upper base plate ( 2 ) and the lower base plate ( 3 ); one end of the clearance ( 4 ) is the optical disk insertion inlet ( 5 ), and the upper and the lower base plates are 80-90 millimeters wide at the optical disk insertion direction; the guiding mechanism comprises a pair of detection bars ( 10 , 11 ) that are symmetrically located at the two sides of the central line ( 1 a ) of the optical disk transport path and capable of rotating around respective rotary pivots, a linkage plate ( 13 ) for making the pair of detection bars ( 10 , 11 ) to move together, and a first stretching spring ( 14 ) making the detection bars ( 10 , 11 ) to rotate according to the direction that makes their detection parts ( 10 a , 11 a ) to contact the periphery of the optical disk, wherein, the detection parts ( 10 a , 11 a ) of the pair of detection bars are located between the plummer ( 12 ) and a delivery roll ( 27 ) of the transport mechanism; the optical disk loading final position detection mechanism comprises a support part ( 20 ) and a trigger bar ( 21 ); one end of the support part ( 20 ) is rotatablely fixed to the upper base plate ( 2 ) near the detection part ( 11 a ) of one detection bar ( 11 ), and its middle is provided with an assorted part ( 20 b ) interacting with the detection bar ( 11 ); the middle of the trigger bar ( 21 ) is rotatablely fixed to the free end of the support part ( 20 ), of which one end is provided with a contact part ( 21 a ) for contacting the periphery of the optical disk, and the other end is connected to the control part ( 40 ).
