Abstract

PURPOSE: To improve the operability of a mechanism for switching the fulcrum of an underslung spring for an optical disk player. CONSTITUTION: A reproducing unit is supported in a case 1 through an underslung spring and a damper 2. A circular arc-shaped guide groove 1a formed in the case 1 is provided with plural recessed parts inside. The guide groove 1a guides a spring hook member 5 supporting the underslung spring. The underslung spring applies tensile force to the member 5 toward the inside of the guide groove 1a. A turning lever 7 is turnably supported at the center of the circular arc of the guide groove 1a, and is provided with a cam 7a abutting on the member 5. By turning the lever 7, the member 5 is thrust out and moved from the recessed part of the guide groove 1a.
