Disc device

A disc device comprising:

• a housing having a tray conveying opening formed at a side surface;
• a tray on which a disc is to be placed;
• a tray conveying mechanism which conveys the tray in a conveying direction through the tray conveying opening, between an ejection position outside the housing and a recording/reproduction position inside the housing;
• a first optical pickup unit provided in a manner capable of moving in a radial direction of the disc with respect to a first surface of the disc at the recording/reproduction position, the first optical pickup unit performing at least one of recording and reproduction of information on the first surface;
• a first traverse chassis movably holding the first optical pickup unit;
• a second optical pickup unit provided in a manner capable of moving in the radial direction with respect to a second surface on a back side of the first surface of the disc at the recording/reproduction position, the second optical pickup unit performing at least one of recording and reproduction of information on the second surface;
• a second traverse chassis movably holding the second optical pickup unit;
• and
• a first biasing member and a second biasing member biasing the first traverse chassis and the second traverse chassis, respectively, in directions of coming closer to each other,
• wherein the first traverse chassis and the second traverse chassis are coupled to each other to turn around a turning axis, and the turning axis is at a position, of the housing, opposite the side surface of the housing and extends in a width direction of the housing orthogonal to the conveying direction and a thickness direction of the housing, and
• at least one of the first biasing member and the second biasing member includes a first end attached to the first traverse chassis and a second end attached to the second traverse chassis, and is inclined with respect to each of the conveying direction, the thickness direction and the width direction.
