Abstract

The invention discloses a picking-up device (10), which consists of case (30) and lens (20) in the case (30), wherein the case (30) contains first bearing part (41) to support lens (20), second bearing part (42) to support lens (20), first separating wall (51) in connection with the first bearing part (41), second separating wall (52) in connection with the second bearing part (42), connecting part (60) in connection with the first separating wall (51) and second separating wall (52); the ultrasonic hardening adhesives (91), (92), (93) are coated on the first bearing part (41), second bearing part (42) and connecting part (60) to fix lens (20) in the case (30), which is convenient to coat on the projecting part (63) of lens (20) and connecting part (60) in the case (30). The strength of case (30) is improved to avoid resonant problem of optical pick-up device (10).

Description

technical field [0001] The present invention relates to a pickup device mounted on, for example, a disk device and capable of reading information on a medium such as a disk. Background technique [0002] image 3 It is a perspective view showing one form of a conventional pickup device. [0003] The collimator lens 520 is attached to the lens attachment portion 535 of the housing 530 . Adhesives 591 , 592 , 593 , and 594 are applied to the upper portions of the pair of bottom-side inclined portions 541 , 542 and the two left and right rail surfaces 551 , 552 of the die-cast housing 530 . Adhesives 591 , 592 , 593 , and 594 are applied to a total of four locations on the peripheral portion 529 of the collimator lens 520 . In this way, the collimator lens 520 is adhesively fixed to the casing 530 . [0004] In addition, an actuator (not shown) is mounted on the actuator mounting portion 580 of the housing 530 . Actuator means a drive device that converts energy into transl...
