Problems solved by technology

[0003] In the above-mentioned optical disc transportation device, the optical disc is clamped between the guide part and the transmission roller of the double-cone structure. During the transport process, scratches may appear on the disc surface in contact with the guide part, so it cannot be applied to all optical discs used.

Embodiment Construction

[0014] In the present invention, a double-cone structure of the transfer roller is adopted, and the diameter of the roller body of the transfer roller is gradually reduced from both ends to the middle. At a position opposite to each cone of the transfer roller, there is provided a follower contacting the outer circumference of the optical disc. And ensure that the driven roller can rotate freely. A further description will be given below in conjunction with the drawings.

[0015] Refer to Figure 1-3 , The present optical disc conveying device includes a conveying roller 4, a guide member 7 located above the conveying roller 4, and an elastic member 10 for pressing the conveying roller 4 to the guide member 7 (see Figure 5 ), and the motor M used to drive the transfer roller 4 to rotate (see Figure 4 ), the roller body of the conveying roller 4 is a double cone structure with a diameter gradually reduced from both ends to the middle, and two rotatable positions are installed on t...

Abstract

The invention discloses a device for conveying an optical disk, which comprises a carrying roller, a guide part positioned above the carrying roller, an elastic part used for pressing the carrying roller towards the guide part, and a motor used for driving the carrying roller to rotate, wherein, the roller body of the carrying roller is a bipyramidal structure with the diameter which is shrunken from the two ends to the middle gradually; at least a turnable driven roller is mounted on the position which is opposite to each pyramidal of the carrying roller on the guide part, the rotating shafts of the driven rollers are positioned in a plane or are parallel to the plane, and the rotating shaft of the carrying roller is positioned in the plane and the plane is perpendicular to the roof of an optical playing device, and the driven rollers which are close to one end of the middle part of the carrying roller tilts upwards to enable the driven roller to contact with only the outer edge of the optical disk when the optical disk is inserted. The device can enable the front side and the back side of the optical disk to be not scratched, is suitable for the optical playing device with two surfaces of the used optical disk as the recording surfaces, and can realize the miniaturization of the optical disk playing device.

Description

Technical field [0001] The present invention relates to an optical disc transport device in an optical disc playback device, in particular to an optical disc transport device that transports the optical disc from an insertion port to a playback position by the rotation of the transport roller when the optical disc is inserted between the transport roller and the guide part. Background technique [0002] When the optical disc is inserted between the transport roller and the guide member, a transport device that transports the optical disc from the insertion port to the playback position by the rotation of the transport roller is known. For example, Japanese Patent Application Publication No. 2005-332461 discloses a conveying roller with a double cone structure, a guide member, an elastic member for pressing the conveying roller to the guide member, and a device for driving the conveying roller to rotate. An optical disc conveying device composed of a motor, which clamps the disc b...
