Claims

[Scope of utility model registration request]

(1) A disk rotating device 2 that rotates a recording or reproducing disk 1, a laser light source 12, and a laser beam 3 emitted from the laser light source 12 that guides the disk 1 (optical components, the laser light source 12, and the An optical device 4 for optical recording or reproducing, which includes a support base 11 that supports optical components; a feeding device 5 that transports the optical device 4 in the radial direction of the disk 1; and a fixed end fixed to the support base 11. 18, an engaging portion 19 extending at an angle with respect to the feeding direction of the optical device 4, and a shielding portion 20 bent at an angle with respect to the retaining portion 19. Part 1
8 and the retaining portion 19 is formed to elastically rotate from the non-operating position to the operating position, with the boundary portion 22 between the retaining portion 19 and the shielding portion 20 serving as a rotation center. Corresponding to the non-operating position, the position is such that the path of the laser beam 3 within the optical device 4 is not blocked, and the engaging portion 1
a beam shielding member 6 formed to be in a position that blocks the passage of the laser beam 3 corresponding to the operating position of the optical device 4; and a position of the laser beam 3 projected from the optical device 4 onto the disk 1; When the optical device 4 is moved so that it is near the outer circumferential edge of the disk 1 or away from the disk 1, it engages with the retaining portion 19 of the beam shielding member 6 and shields the laser beam. a fixing protrusion 7 for rotating the member 6 to the operating position; An optical disc device comprising:

(2) The optical disc device according to claim 11, wherein the beam shielding member 6 is a bent plate spring.
