20090276798 | Optical Disk Transport Device for Optical Disk Player - An optical disk transport device for optical disk player comprises a carrying roller, an optical disk guiding part located above the carrying roller, an elastic part for pressing the carrying roller towards the optical disk guiding part, and a motor for driving the carrying roller to rotate. The roll body of the carrying roller is of a bipyramidal structure with the diameter gradually decreasing from the two ends to the middle. The positions on the optical disk guiding part opposite to each pyramid of the carrying roller are provided with at least one rotatable driven roller. The rotating axes of each driven roller are located in the plane which is the rotating axis of the carrying roller located in and is vertical to the roof of the optical disk playing device, or are parallel to the plane. The ends adjacent to the middle of the carrying roller of each driven roller slant upwards, so as to make the driven rollers only contact the outer margin of the optical disk when the optical disk is inserted. The optical disk transport device can protect the front and back surfaces from being scratched during the process of transporting the optical disk. It is especially suitable for the optical disk playing device using the optical disks with the both surfaces being recording surfaces, and can implement the miniaturization of the optical disk playing device. | 11-05-2009 |
20090282426 | Optical Disk Player Capable of Monitoring the Optical Disk Status - An optical disk player, which comprises: a shell, a plummer fixed in the shell, an optical disk transport mechanism, a guiding mechanism, an optical disk loading final position detection mechanism, and a control part; the shell is 80-90 millimeters wide at the optical disk insertion direction; the detection parts of the guiding mechanism are located between the plummer and the delivery roll of the transport mechanism; the optical disk loading final position detection mechanism comprises a support part and a trigger bar; one end of the support part is rotatablely fixed to the upper base plate near the detection part of one detection bar, and its middle is provided with an assorted part interacting with the detection bar; the middle of the trigger bar is rotatablely fixed to the free end of the support part, of which one end is provided with a contact part for contacting the periphery of an optical disk, and the other end is connected to the control part. When an optical disk is at the playing position, a part of the optical disk will be exposed out of the shell of the optical disk player, so, when the optical disk is played, the status of the optical disk in the optical disk player can be intuitively seen from the outside. | 11-12-2009 |
20100095313 | Optical Disk Transport Device for Optical Disk Playing Device - An optical disk transport device for optical disk playing device comprises: a delivery roll and an optical disk guiding device located at the optical disk insertion inlet; a pair of detection bars provided with detection parts contacting the periphery of the optical disk inserted from the optical disk insertion inlet, and the detection bars being capable of freely rotating around respective rotary pivots; a linkage plate for controlling the pair of detection bars to move together; an elastic part making the detection bars to rotate according to the direction that makes the detection parts to contact the periphery of the optical disk; and an optical disk baffle for stopping the transport of the small diameter optical disk as the center of the small diameter optical disk passing the center of the plummer; the detection parts of the pair of detection bars are located between the delivery roll and the plummer. The optical disk transport device utilizes simple structure, to implement that no matter what posture the playing device is at, it can all transport the small diameter optical disk to the plummer safely. | 04-15-2010 |
20100095314 | Optical Disk Loading Final Position Detection Device - An optical disk loading final position detection device comprises: an optical disk guiding device and a delivery roll located at the optical disk insertion inlet; a pair of detection bars provided with detection parts contacting the periphery of the optical disk of big diameter or small diameter inserted from the optical disk insertion inlet, and the detection bars being capable of freely rotating around respective rotary pivots; a support part, one end of the support part being rotatablely fixed to the upper base plate near the detection part of one detection bar, the middle of the support part being provided with an assorted part interacting with the detection bar; and a trigger bar, the middle of the trigger bar being rotatablely fixed to the free end of the support part, one end of the trigger bar being provided with a contact part for contacting the periphery of an optical disk, and the other end being connected to a control part. While the detection bars are rotating, the support part makes the trigger bar to move towards the direction directly facing the central line, so, the trigger bar will not extrude out of the maximum outer diameter of the optical disk along the optical disk transport direction, so as to implement miniaturizing the optical disk playing device. | 04-15-2010 |
20110247024 | Compact Disc Centering Apparatus of Compact Disc Player - A compact disc centering apparatus of a compact disc player includes carrying rollers which are disposed within a compact disc entry on the opposite sides thereof and a compact disc guiding; a pair of detection rods capable of synchronized rotating, which is disposed between a support plate and the compact disc entry. The apparatus also includes a control device and a trigger device, wherein, an engaging portion is disposed on the control device and extends along the direction in which the control device moves, and an engaged portion is disposed on the trigger device and engages with the engaging portion. When the engaged portion is located in the engaging portion, the contact between the engaging portion and the engaged portion makes the trigger device rotate and stop at a position such that the center of the compact disc is coincident with the center of the support plate. The structure of the compact centering apparatus according to the present invention is extremely simple, which enables the center of the compact disc to stop at a position coincident with the center of the support plate, and the compact disc does not return in the direction toward the compact disc entry even if there exists the effect of a reset spring of the trigger device. | 10-06-2011 |
