    摘要： An optical pickup includes a lens holder; an objective lens provided on the lens holder and having an effective region for collecting light from a light source and an edge located outer to the effective region; and a lens protector provided on the lens holder. The lens protector protrudes toward an optical disc more than the objective lens. The edge of the objective lens includes a convexed portion protruding toward the optical disc. An apex of the effective region of the objective lens protrudes toward the optical disc more than the convexed portion of the edge. A straight line connecting a part of the edge of the objective lens and a part of the lens protector is closer to the optical disc than the apex of the effective region of the objective lens.

    摘要： An optical pickup device has a DVD/CD laser diode for emitting a DVD/CD laser beam as linear polarized light, and a BD laser diode for emitting a BD laser beam. The optical pickup device has a dichroic mirror that regularly reflects a part of the DVD/CD laser beam, transmits a part of the DVD/CD laser beam, and transmits return light of the BD laser beam. The dichroic mirror is formed so that a product of reflectance of outward light of the DVD/CD laser beam and transmittance of return light of the DVD/CD laser beam becomes 20% or more to 25% or less. A light receiving element receives the return light of the DVD/CD laser beam transmitted through the dichroic mirror or the return light of the BD laser beam transmitted through the dichroic mirror.

    摘要： In an electronic device including a temperature sensor and an electronic component which is a heat generation source, the temperature is measured while the influence of heat from the electronic component is reduced. The electronic device includes: a base formed of a resin material; a board which is disposed at one side of the base, and includes an electronic component and a temperature sensor; and a heat sink which is disposed at the other side of the base for dissipating heat generated by the electronic component. The heat sink includes an extension part extending from the other side of the base toward a position of the board at which the electronic component is provided.

    摘要： A light emitting device includes a base, a light-emitting module, and a shielding case. The light-emitting module is fixed to the base via a curved flexible printed-circuit. The shielding case fixed to the base in such a manner that the light-emitting module is held in a position to resist a restoring force of the flexible printed-circuit which is generated by the curve of the flexible printed-circuit. The light-emitting module includes a heat source, and the shielding case includes a projection. The projection controls movement of the light-emitting module in a direction perpendicular to the direction in which the light-emitting module is held by the shielding case. The projection and the light-emitting module are bonded to each other with silicone.
