Patent ID: 8202404

Claim:
A surface treatment device for supplying a surface treatment liquid to the inside of a treatment cell while rotating the treatment cell containing a workpiece, thereby performing a surface treatment on the workpiece, wherein the surface treatment device comprises positive electrode supporting means for supporting a positive electrode so that the positive electrode can be used for a surface treatment, wherein the positive electrode supporting means comprises: a positive electrode supporting member for supporting the positive electrode; a tray supporting member for supporting a positive electrode tray; raising and lowering means for moving the positive electrode vertically via the positive electrode supporting member; positive electrode moving means for moving the positive electrode horizontally via the positive electrode supporting member; tray moving means for moving the positive electrode tray horizontally via the tray supporting member; and connecting means through which the positive electrode supporting member and the tray supporting member are connected to each other, and wherein the connecting means is formed so as to connect both the supporting members when the positive electrode starts moving from above a positive electrode retaining tank or from above the treatment cell by the positive electrode moving means and when the positive electrode tray is located below the positive electrode by the tray moving means.
