Power it By functioning as the respective cams, the driving of a large number of members can be controlled, so that the number of members can be further reduced, the driving force transmission path is simplified, and malfunctions and the like hardly occur. Therefore, a disk device that is resistant to vibration can be configured.
- the regulating arm 231 can be displaced via the slide link 114 and the link arm 113 in accordance with the displacement of the pick swing cam plate 138 for driving the pick arm 130, the respective driving members are arranged. Compared to the case of installing, the simplification of the mechanism and the saving of required space can be realized.
- the regulating arm 231 can be set at the retracted position at both left and right ends of the slide link 114, the pick swing cam plate 138 that moves in the opposite direction between the front and rear during disc playback and disc insertion and ejection is provided. Even if there is, the regulating arm 231 can be driven in conjunction with this.
- the regulating arm 231 and the tension arm 115 can also be displaced via the slide link 114 and the link arm 113. Compared to the case where a driving member is provided, simplification of the mechanism and saving of required space can be realized.
- the slide link 114 can have the regulating arm 231 at the retreat position and the tension arm 115 at the abutment position at the left and right ends, opposing front and rear directions can be used during disc playback and disc insertion and ejection. Even if the pick swing cam plate 138 moves to the position, the regulating arm 231 and the tension arm 115 can be driven in conjunction with the pick swing cam plate 138.
- the present invention is not limited to the above embodiments.
