Turntable having elastic layer with high contact pressure portion |
| 摘要 |
Provided is a turntable for rotatably supporting a disc member on a disc support surface in a state where the disc member is sandwiched and held between the turntable and a clamp member placed opposite thereto, wherein the disc support surface is provided with an elastic layer having a predetermined width, and configured to project from the disc support surface, and at least one of an outer peripheral part and an inner peripheral part of the elastic layer is provided with a high contact pressure portion of which a contact pressure generated by pressing the clamp member thereto is higher than that of other portion. |

1. A turntable for rotatably supporting a disc member on a disc support surface in a state where the disc member is sandwiched and held between the turntable and a clamp member placed opposite thereto, wherein
the disc support surface is provided with an elastic layer having a predetermined width, and configured to project from the disc support surface, at least one of an outer peripheral part and an inner peripheral part of the elastic layer is provided with a high contact pressure portion of which a contact pressure generated by pressing the clamp member thereto is higher than that of any portion of the elastic layer other than the high contact pressure portion, the high contact pressure portion is formed by an edge portion projecting to form a predetermined angle in a vertical cross section which cuts across the disc support surface in its radial direction, and an inclination angle of an upper surface of the elastic layer is from about 0.5° to about 45°.
