<P>PROBLEM TO BE SOLVED: To simplify the constitution of the opening and closing mechanism of the shutter of an objective lens and also to assemble an optical pickup device easily. <P>SOLUTION: The optical pickup device is equipped with: an optical pickup 16 which records and reproduces data; guide shafts 22, 23 which supports the optical pickup 16 so as to be movable in the radial direction of an optical disk 7; a transfer mechanism 18 which moves the optical pickup 16 in the radial direction of the optical disk 7; and a shutter member 43 which opens and closes an objective lens 19. The transfer mechanism 18 has: a feeding screw 32 which moves the optical disk 7; a transfer block 33 which is inserted into the guide shaft 23 between guide pieces 27, 28 and which is movable to the optical pickup 16; and an energizing member 35 which energizes the transfer block 33 to one direction. The shutter member 43 is configured so that its base end side is pivotally supported on the transfer block 33 and the middle part is pivotally supported on the pickup 16, and opens and closes the objective lens 19 with its tip side in accordance with the transfer of transfer block 33. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
