Description of the Invention: [Technical Field of the Invention] Disc-shaped recording such as transfer of a disc or a magnetic disc, particularly relating to a disc having a long wear life. The present invention relates to a disc transfer member of a medium, a transfer member. [Prior Art] The CDCC has proposed a disc recording and/or playback device, which uses an ompact Disk: DC-R〇M (Read Only Memory *), etc., called a disc or a magnetic disc (10) agnetlc Dlsk And the disc-shaped recording medium is recorded and/or played. κ Dingbei. Μ 口唬 In order to record and/or broadcast the disc entrance and exit. In order to make the "Xioni Tishan 4" long-shaped slit-like body, that is, the optical disc, the disc-shaped transfer structure of the disc-shaped structure has the insertion force and the discharge force to the disc. Recording and playback devices as well as their Japanese, for example, pq 9nn〇one. Further, it is not disclosed in Japanese Patent Publication No. 98 (Patent Document 1). The second snippet is recorded in a state in which the material roll m of the patent reading 1 and the monument 110 are spear. The Yuan Zhao system 1 〇〇 system includes .± mqn , $ ,®, a conventional transfer trousers μ (four) 邛 101, a lower cylindrical portion 102, and the same portion m and the lower cylindrical portion 102 Between the formation of the "shaped groove shape 316439 Ϊ 274326 m 103, through the shaft mounting hole (10) provided in the central portion of the transfer member _ when: the rotation center of the coffee roll is fine.

Handling the second:: the other-transfer roller's "shaped groove" to be maintained, and load _, 798 (four) ((four), [Description of the Invention] Figs. 46 and 47 and related to the illusion [Problems to be solved by the invention] J: The disc transfer member for the disc recording and playback apparatus is transmitted by the above and f mode. The transfer member is composed of The circumferential direction continuously forms the right=fog, and the grooved grooved drum is formed. Because the part: the shape or the V-shaped tip touches the disc, the volume is lost. "The upper and lower end edges change: the intersection is large, and there is wear and tear. The powdery piece is so powerful that the original piece of the worn piece is shouted. The edge touches the slope of the drum: By ensuring the handling force, the handling force of the disc will be increased because the rigidity of the rubber of the cylinder is lowered, that is, the size of the text is large. It means force. Therefore, if it is only for making it; The invention of the transfer member is for understanding the problem of 沬 + + low.

The same reference numerals will be given to the same reference numerals, and the description will be omitted. In the embodiment, the central circle of the transfer drum is divided into three stages: the upper part, the central part, and the lower part, and the upper lower part or the central part P and the outer peripheral surface of the disc are batched. The above Jr is not limited to this, and may be divided into a part of the outer peripheral surface of the disc by four or more stages. In the case of the assembly mode, the case where the transfer drum has its central portion ' has been described, but the present invention is not limited thereto, and may be assembled to the fixed shaft. Referring to the fourth embodiment of the present invention, the present invention is not limited to the embodiment shown in the same scope of the invention, and the present invention is modified. , or within the scope of the search, various modifications may be applied or 316439) 2 1274326 [Industrial Applicability] / According to the present invention, a transfer mechanism for disc transfer may be provided in a line extending in the thickness direction thereof. The disc member is configured to convey the disc, thereby ensuring the handling force of the disc: the surface is worn by the line contact, and can be advantageously used as a disc transfer roller.
