Abstract: PROBLEM TO BE SOLVED: To provide an optically coupled device which is simple in structure and capable of preventing dust or foreign particles from penetrating into an optical path provided within. SOLUTION: A light-emitting device 20 and a photodetector 21 are housed in a easing 22. An elastically deformable, movable body 23 is provided to the upside of the casing 22 in one piece covering a light-transmitting chamber S provided inside the casing 22. When an external force is applied to the movable body 23, the movable body 23 is elastically deformed to shut off an optical path X. When an external force is removed from the movable body 23, the movable body 23 recovers its original shape by its own elasticity to form an optical path again.

Abstract: PROBLEM TO BE SOLVED: To provide an actuator for optical pickup that efficiently generates a thrust for driving a lens holder in a focusing direction. SOLUTION: The actuator for optical pickup is supported on an axis 16 and designed to drive the lens holder 11, which has an objective lens 12, in the focusing direction that is parallel to the axis 16 and in the circumferential direction B that is around the axis 16. This actuator is equipped with magnets 13 for magnetizing the lens holder in the same direction and a coil 14, which is wound on the entire circumference of the axis 16, for driving the lens holder in the focusing direction. The magnets 13 are arranged in point symmetry around the axis 16 along the outer circumference of the lens holder 11. The coil 14 for driving in the focusing direction is fixed to a base 10, with a space from the magnets 13, on the outside of the magnets 13.

Abstract: PURPOSE:To dispense with a die for forming a shielding material, to facilitate changing the shape and position of a window, and to enable the width of the window smaller, by providing a shielding member formed by depositing shielding material in a preset thickness thereto on the surface of a translucent resin. CONSTITUTION:In the case of a reflective photo interrupter, a light emitting device 1 and a light receiving device 2 are mounted on the same lead frame 4 and internally connected via gold line 5. And when it is completed as a finished product, a lead frame 9 for connection is provided to prevent a mold body on the light emitting side from separating from a mold body on the light receiving side. After this is molded in a translucent resin 3, it is coated by a shielding member 10 which is a shielding type paint or metal. If the shielding member 10 is the paint, a method of spraying, printing, dropping or dipping it into the paint can be considered. Also, if it is the metal, it can be formed by vacuum evaporation or plating.
