実用新案登録請求の範囲を次のように補正する
。Amendment November 12, 1980 The scope of claims for utility model registration is amended as follows.
【実用新案登録請求の範囲】
記録媒体上に光スポツトを投射する対物レンズ
を保持する保持体を弾性支持体により移動自在に
支持した光学系支持装置において、前記弾性支持
体に、その延在方向のまわりに発生するねじれに
対するダンピング効果を有するように凹凸加工を
施したことを特徴とする光学系支持装置。[Claims for Utility Model Registration] An optical system support device in which a holder for holding an objective lens for projecting a light spot onto a recording medium is movably supported by an elastic support. 1. An optical system support device, characterized in that an optical system support device is provided with an uneven surface so as to have a damping effect against torsion generated around the optical system support device.

を保持する保持体を弾性支持体により移動自在に
支持した光学系支持装置において、前記弾性支持
体に、その延在方向のまわりに発生するねじれに
対する耐ねじれ強度を有するように凹凸加工を施
したことを特徴とする光学系支持装置。 In an optical system support device in which a holder holding an objective lens for projecting a light spot onto a recording medium is movably supported by an elastic support, the elastic support has resistance against twisting occurring around the direction in which the elastic support extends. 1. An optical system support device characterized by having a concavo-convex process to provide torsional strength.
