光ディスクに対してレーザ光を照射する光ピックアップ装置と、
前記光ピックアップ装置を移動自在に支持するガイドシャフトと、
前記光ディスク側から前記ガイドシャフトの一端部を支持する第１支持部と、
前記第１支持部とは対向して配置され前記第１支持部との間に挿入された前記ガイドシャフトの前記一端部を前記光ディスクと反対側から支持する第２支持部と、
前記ガイドシャフトの前記一端部を前記第１支持部及び前記第２支持部を介して保持するベースと、を備え、
前記第１支持部または前記第２支持部の少なくとも一方の他方に対向する面は前記ガイドシャフトの軸方向で凸形状であることを特徴とする光ディスク装置。 An optical pickup device for irradiating an optical disc with laser light;
A guide shaft that movably supports the optical pickup device;
A first support for supporting one end of the guide shaft from the optical disc side;
A second support part arranged to face the first support part and to support the one end part of the guide shaft inserted between the first support part from the side opposite to the optical disk;
A base that holds the one end portion of the guide shaft via the first support portion and the second support portion;
An optical disc apparatus characterized in that a surface facing at least one of the first support portion and the second support portion is convex in the axial direction of the guide shaft. 前記ガイドシャフトを前記第１支持部と前記第２支持部との間に挿入する方向に最大角度傾けた場合前記ガイドシャフトが前記第１支持部に接する第１の点と、前記第１支持部と前記第２支持部との間で前記方向と逆方向に最大角度傾けた場合前記ガイドシャフトが前記第１支持部に接する第２の点と、を結ぶ線のガイドシャフト側に、前記第１支持部の凸形状の頂点は突出していることを特徴とする請求項１記載の光ディスク装置。   A first point at which the guide shaft contacts the first support portion when the guide shaft is inclined at a maximum angle in a direction of insertion between the first support portion and the second support portion; and the first support portion. When the maximum angle is inclined in the direction opposite to the direction between the first support portion and the second support portion, the guide shaft is connected to the second point at which the guide shaft is in contact with the first support portion. 2. The optical disk apparatus according to claim 1, wherein the convex vertex of the support part protrudes. 前記ガイドシャフトを前記第１支持部と前記第２支持部との間に挿入する方向に最大角度傾けた場合前記ガイドシャフトが前記第２支持部に接する第１の点と、前記第１支持部と前記第２支持部との間で前記方向と逆方向に最大角度傾けた場合前記ガイドシャフトが前記第２支持部に接する第２の点と、を結ぶ線のガイドシャフト側に、前記第２支持部の凸形状の頂点は突出していることを特徴とする請求項１記載の光ディスク装置。   A first point where the guide shaft is in contact with the second support portion when the guide shaft is inclined at a maximum angle in a direction of insertion between the first support portion and the second support portion; and the first support portion. When the maximum angle is inclined in the direction opposite to the direction between the first support portion and the second support portion, the guide shaft is connected to the second point where the guide shaft contacts the second support portion. 2. The optical disk apparatus according to claim 1, wherein the convex vertex of the support part protrudes. 前記第１支持部と前記第２支持部とは、前記ガイドシャフトの軸方向にずれて配置されていることを特徴とする請求項１記載の光ディスク装置。   2. The optical disc apparatus according to claim 1, wherein the first support portion and the second support portion are arranged so as to be shifted in the axial direction of the guide shaft. 前記第１支持部は前記ベースと一体であることを特徴とする請求項１記載の光ディスク装置。   2. The optical disc apparatus according to claim 1, wherein the first support part is integral with the base. 前記第２支持部は前記ベースと一体であることを特徴とする請求項１記載の光ディスク装置。   2. The optical disc apparatus according to claim 1, wherein the second support part is integral with the base. 前記第１支持部または前記第２支持部の少なくとも一方に細隙を設けたことを特徴とする請求項１記載の光ディスク装置。2. The optical disc apparatus according to claim 1, wherein a slit is provided in at least one of the first support portion and the second support portion. 前記第１支持部または前記第２支持部の少なくとも一方を有して前記ベースに固定される支持部材を備え、前記ガイドシャフトの前記一端部の側方にある前記光ディスクに対して略直角な前記支持部材の内側面は、前記ガイドシャフトの軸方向で凸形状であることを特徴とする請求項１記載の光ディスク装置。A support member that has at least one of the first support portion and the second support portion and is fixed to the base, and is substantially perpendicular to the optical disc on the side of the one end portion of the guide shaft. The optical disk apparatus according to claim 1, wherein an inner side surface of the support member has a convex shape in an axial direction of the guide shaft. 前記第１支持部または前記第２支持部の少なくとも一方を有して前記ベースに固定される支持部材を備え、前記ガイドシャフトの前記一端部の側方にある前記光ディスクに対して略直角な前記支持部材の壁部に細隙を設けたことを特徴とする請求項１記載の光ディスク装置。A support member that has at least one of the first support portion and the second support portion and is fixed to the base, and is substantially perpendicular to the optical disc on the side of the one end portion of the guide shaft. 2. The optical disk apparatus according to claim 1, wherein a slit is provided in the wall portion of the support member.
