Abstract
An optical pick-up device includes: a yoke plate having yokes formed at a front side where a magnetic body and a magnetic driving coil are positioned to drive an objective lens; a frame molded to the yoke plate in such a manner that a portion of the rear side of the yoke plate is inserted thereinto; and a PCB with at least two portions fixed to the frame, for applying a drive signal to the magnetic driving unit. Since the frame is press-fit to the yoke plate and the PCB with several portions coated with the adhesive is fixedly attached to the frame, it is not necessary to use an engaging member such as a screw, so that its assembly can be improved and the frame and the PCB can be prevented from being shaken.
Claims19
An optical pick-up device comprising:
- a yoke plate having yokes formed at a front side where a magnetic body and a magnetic driving coil are positioned to drive an objective lens;
- a frame fixed to the yoke plate in such a manner that a portion of the rear side of the yoke plate is inserted thereinto;
- and
- a PCB with at least two portions fixed to the frame, for applying a drive signal to the magnetic driving coil.
An optical pick-up device comprising:
- a yoke plate having yokes formed at a front side where a magnetic body and a magnetic driving coil are positioned to drive an objective lens;
- and
- a frame molded to the yoke plate in a state that a portion of the rear side of the yoke plate is inserted thereinto.
An optical pick-up device comprising:
- a yoke plate having yokes formed at a front side where a magnetic body and a magnetic driving coil are positioned to drive an objective lens;
- a frame fixed to a rear side of the yoke plate, wherein an insertion portion is formed at the rear side of the yoke plate and an insertion hole is formed at the frame so that the insertion portion is press-fit to the insertion hole, thereby fixing the frame to the yoke plate;
- and
- a PCB with at least two portions fixed to the frame, for applying a drive signal to the magnetic driving coil.
