Patent ID: 8522262

Claim:
An optical-disc player, comprising: a pair of optical-disc sensor levers ( 10 ) ( 15 ) respectively having a detection part capable of being embedded into the periphery of an optical disc (D) inserted into an optical-disc inserting opening ( 6 ) and rotating immediately once the detection part driven by the optical disc; a conveying roller ( 35 ) used for clamping the optical disc on an optical-disc guide plate ( 21 ) and conveying the optical disc between the optical-disc inserting opening and a turntable ( 221 ) through the rotation of a motor ( 27 ); a roller supporting component ( 36 ) used for supporting the conveying roller; a driving member ( 37 ) embedded with the roller supporting component and used for driving the conveying roller and the optical-disc guide plate to be engaged and disengaged during the reciprocating motion; a cam gear ( 26 ) used for moving the driving member; a driving gear ( 30 ) used for driving the cam gear via a rotary force of the motor; switches ( 13 ) ( 14 ) ( 38 ) used for controlling the rotation of the motor, and a traverse mechanism ( 22 ) having a pick-up ( 25 ) and the turntable, wherein the component is embedded with the roller supporting component and used for driving the conveying roller and the optical-disc guide plate to be engaged and disengaged, on the driving member being an E-shaped cam hole ( 37 a ); and a convex portion ( 26 e ), a first toothed portion ( 26 b ) and a second toothed portion ( 26 c ) formed on the cam gear, and a toothless portion ( 26 d ) are formed between the two toothed portions; the optical-disc player also comprising: a shaking component ( 31 ) embedded onto the driving gear and shaking along with the rotation of the driving gear, and a hook component ( 32 ) supported by the shaking component, wherein the hook component has a contact portion ( 32 b ) capable of being embedded with the optical-disc sensor lever and a hook portion ( 32 a ) capable of being embedded with the convex portion of the cam gear; when the optical disc taken out from the optical-disc inserting opening, the hook portion embedded with an end section ( 26 p ) of the convex portion by the disembedding between the optical-disc sensor lever and the contact portion; the cam gear driven to rotate by the shaking of the shaking component via the hook component and the driving gear engaged with the first toothed portion; the cam gear driven to rotate continuously and the driving member driven to move to a mobile terminal position, and then the conveying roller and the optical-disc guide plate disengaged from each other.
