Patent ID: 7191454

Claim:
A disc driving device having a function of performing loading operation to transfer a disc, which is a disc-shaped recording medium, in its radial direction, and chucking operation to transfer the disc substantially in the direction of its thickness, the disc driving device comprising: plural roller members that contact an outer circumference of the disc and thus support the disc; a roller arm that sways parallel to the radial direction of the disc and has the roller members arranged at its swaying end; a chucking member engaged with a center hole of the disc; a chucking arm that sways substantially in the direction of the thickness of the disc and has the chucking member arranged at its swaying end; a single driving source that gives rotational driving force to at least one of the plural roller members; and a cam driven by the single driving source and having provided thereon a centering cam groove or cam ridge for regulating the swaying of the roller arm and a chucking cam groove or cam ridge for regulating the swaying of the chucking arm; wherein as the centering cam groove or cam ridge regulates the swaying of the roller arm, the disc transferred in the radial direction by rotational driving of the roller members is positioned at a predetermined position, and as the chucking cam groove or cam ridge regulated the swaying of the chucking arm, the disc situated at the predetermined position is transferred substantially in the direction of the thickness by the chucking member.
