摘要： PURPOSE:To lead out the position control signal of a laser light by the incident light amt. to each factor and to reduce the man/hour in correcting a misregistration by dividing a detector in plural factors electrically by aligning to the position of a laser light. CONSTITUTION:A detector 100 has the light receiving pat multi-divided in a matrix shape in X direction and Y direction within the plane about parallel to the fitting face 100-2 of a board 100-1 and the board 100-1 is tacked by screw to the fitting face of a pickup case. The board 100-1 is then subjected to screw tightening after performing the position adjustment so that the light flux section 110 of the laser light may completely be converged in the detector 100 within the fitting face, and the detector 100 is fixed. A current is then induced at the element unit radiated by the laser light on the detector 100, which generates a current in the zone 120 and 130 bisected to the right and left by xio.

摘要： PURPOSE:To enable an automatic assembling by providing a positioning member having a terminal insertion hole at the center part of a movable part covering a shaft and a bearing. CONSTITUTION:The upper part of a terminal insertion hole 22e is formed in radial shape making width wider in proportion to approaching to the upper part and so that an aperture hole 22f is provided at the upper part, a coil terminal wire can be easily inserted within the terminal insertion hole 22e and also, the coil terminal wire inserted once within the terminal insertion hole 22e is prevented to come out from the aperture hole 22f. Furthermore, so that the upper part of a shaft 9 is covered with a positioning member 22, the invasion of microscopic dust to a space between the shaft 9 and a bearing 16 is prevented and with smoothing the turning of a movable part 13, the rotation accuracy of an objective lens 4a can be improved. Thus, working to insert the coil terminal wire to the terminal insertion hole is made easy and it is possible to perform the automatic assembling.

摘要： PURPOSE:To facilitate assembling and adjustment and to reduce the cost by sticking filters to end faces of plural optical fibers each of which is provided with a flat set reference face in one position at least on the outside peripheral surface and arranging these optical fibers close on a flat surface. CONSTITUTION:Optical fibers 14, 15, and 16 which have clads 22 whose sections are square or are provided with flat faces 24 in one part of clads 23 are arranged on an upper face 13 of a flat plate 12. Optical axes of optical fibers 14 and 15 are set to a straight line, and the optical axis of the optical fiber 16 is made orthogonal to optical axes of optical fibers 14 and 15. End faces of optical fibers 14 and 15 are cut at 45 deg. and filters 18 and 19 are stuck there, and a filter 20 is stuck to the end face of the optical fiber 16. The filter 18 permits the light having a wavelength lambda3 to pass through but reflects the light having a wavelength lambda4. The filter 19 permits the light having the wavelength lambda3 to pass through, and the filter 20 permits the light having the wavelength lambda4 to pass through. Thus, a device where assembling and adjustment of a light branching point 17 are made easy is produced.

摘要： PURPOSE: To simplify and automate the adjustment of the optical axis angle of an objective lens by installing the mounting position of the objective lens and a base for supporting a coil bobbin for mounting the objective lens so as to be positioned at the same side with respect to said coil bobbin, and reducing the distance between the fitting position of the objective lens and the fitting face of the base.
CONSTITUTION: The actuator base 1502 is installed at the side where the objective lens 501 of the coil bobbin 1505 is fitted, and in the center of the actuator base 1502 a hole 1511 is drilled to insert the objective lens 1502 a hole 1511 is drilled to insert the objective lens 501. Where the pitch of the fitting hole 1509 of the base 1502 and a distance between the fitting face of the base 1502 to a case 1 and the objective lens 501 are (a) and (d), respectively, an optical axis shift Δ when the optical axis m-m' of the objective lens 501 is angle- adjusted can be obtained according to the expression (I). If the fitting face of the actuator base 1501 and the objective lens 501 are disposed at the same side of the coil bobbin 1505, the optical axis shift Δ caused by the angle adjustment of the optical axis of the objective lens 501 can be significantly reduced.
