摘要： An optical pickup has a support pedestal integrally formed at a rear end portion of a mounting surface of a base. A pair of left and right leg portions extend forwardly from both side edge portions of a rear end portion of a resilient plate. A fixing hole is penetratingly provided in each of the leg portions on a phantom line passing through a central axis of a photodiode and extending in a horizontal transverse direction. Each fixing screw is screwed into a threaded hole in the mounting surface through each fixing hole, so as to press the rear end portion of the resilient plate against the support pedestal.

摘要： An optical pickup has a pair of left and right leg portions formed integrally at both side edge portions of a rear end portion of a resilient plate. The leg portions extend forwardly along a horizontal longitudinal direction. A pair of fixing holes are penetratingly provided in the respective leg portions on a transverse phantom line passing through a central portion of the resilient plate and extending in a horizontal transverse direction and at positions spaced apart an equal interval from a longitudinal phantom line passing through the central portion of the resilient plate and extending in the horizontal longitudinal direction. A pair of fixing screws are screwed into a pair of threaded holes in a mounting surface of a base through the fixing holes, thereby fixing the leg portions to the mounting surface.

摘要： An optical pickup has a laser mounting surface formed around an opening portion of a laser hole while a notch groove ranging from the laser mounting surface to an operating hole is formed in a laser hole side wall portion. A fitting piece removably fitted into the notch groove is provided integrally with a metal holder which is provided for supporting a photodiode and which is locked in the laser mounting surface. The operating hole is defined between a forward end of the fitting piece and an inner end of the notch groove. A laser diode is fitted into a lock hole of the holder coaxial with the laser hole while a radiator plate is attached to the outer surface of the holder. Thus, the laser diode is held between the holder and the radiator plate.

摘要： An attachment part of a mirror fixture is housed in a recess part of an optical system unit and edge-like end margins of a pair of opposed engagement piece parts of the attachment part are retained on a pair of opposed walls and of the recess part in a press state. An operational piece part is extended backward from each of the engagement piece parts and housed in an operational jib insertion recess-in part 10 of the optical system unit. If the tip of an operational jig such as tweezers is inserted into the recess-in part and the operational piece parts are deformed inward, the engagement pieces parts also become deformed inward and the retention state with the walls is released.

摘要： An optical pickup includes a radiating plate made to abut against a rear surface of a laser diode by positioning an engaging hole provided penetratingly in a central portion of the radiating plate concentrically with the laser diode. Slits are formed in the radiating plate to form a pair of tongues in the manner of point symmetry about an axis of the engaging hole. Screw insertion portions formed in the respective tongues are communicates with the slits. As screws are passed through the screw inserting portions and are screwed in, the radiating plate is secured to the base. When the screws are screwed in, the axis is positioned on a phantom line connecting points of application of force generated at proximal end portions of the tongues. Distances from the axis to the respective points of application of force are set to be substantially identical.

摘要： An optical pickup has a base having a screw hole, a holder attached to the base, a laser diode held by the holder, a leaf spring, and an adjusting screw. The holder is formed of a substantially rectangular metal plate having short and long sides and is formed with a laser hole for fitting the laser diode through a center thereof. An angular fulcrum is formed at the center of a back surface of the holder along a direction parallel to the short side. The fulcrum is brought into abutment with the base via the leaf spring and one end of the holder is urged toward the base by the leaf spring. The holder is temporarily secured to the base by screwing the adjusting screw through an insertion hole formed at the other end of the holder into the screw hole of the base.

摘要： In a biaxial actuator for an optical pickup, rising pieces are bend-formed on a base member on which a lens holder having an objective lens is placed in such a way as to be able to displace in a focusing direction and in a tracking direction. The strength of the base member is increased by setting the width of the bend-formed portion at the root of each of the rising pieces in such a way as to be larger than the width of any other part of the associated rising piece. Preferably, the shape of a side elevation section of each of the rising pieces is set to be a trapezoid.

摘要： In an optical pickup device with a defocus adjustor used for adjusting a position of a photo-sensor against an optical system, the photo-sensor is mounted on a flexible printed circuit board, and the flexible printed circuit board is fixed on a plate spring. A first end of the plate spring with the flexible printed circuit board is fixed on a fixing face of a holder. Since the fixing face of the holder is inclined and the plate spring is formed flat with no bending portion, the plate spring is warped for generating a stress when the second end of the plate spring is fixed on the holder by an adjusting screw. The position of a photo-sensing face of the photo-sensor can be fine adjusted by tightening or loosening the adjusting screw.
摘要翻译： 在具有用于调节光传感器相对于光学系统的位置的散焦调节器的光学拾取装置中，光传感器安装在柔性印刷电路板上，柔性印刷电路板固定在板簧上。 具有柔性印刷电路板的板簧的第一端固定在支架的固定面上。 由于保持器的固定面倾斜并且板簧形成为平坦且没有弯曲部分，所以当弹簧的第二端通过调节螺钉固定在支架上时，板簧翘曲以产生应力。 光传感器的感光面的位置可以通过拧紧或松开调节螺丝来调整。

摘要： In a pickup 5 laterally moving by being guided at its one side by a main shaft 4, an inclined piece 5a tilted frontwardly and obliquely downwardly in an opening portion 1a inside a chassis 1 is opposite to the shaft 4. A screw 6 for adjusting the tilt angle of the pickup 5 is obliquely upwardly or downwardly screwed into the inclined piece 5a, and its lower part is placed inside the pickup 5. A flange-like holding portion 6A which is integral with the lower part of this screw 6 is fitted to the opposite opening edge 1b, and the bottom surface edge 6b partially abuts against the chassis 1 top surface and the edge 6b laterally moves by sliding along the top surface when the pickup 5 laterally moves. The edge 6b slides along the top surface near the edge 1b when the pickup 5 laterally moves.
