  • Patent number: 7733408
    Abstract: A solid-state image sensor, a transparent cover, a DSP, a wiring board and the like are sealed in a sealing portion by molding of a synthetic resin, and fixed to an imaging unit. At this time, a portion of the transparent cover is exposed from the sealing portion. The optical path fixing device and the imaging unit sealed by the sealing portion are fixedly combined by engagement of hook engaging portions and hook portions, in a state where the lower end surface of a lens barrel comes into contact with the exposed portion. As the result, positioning accuracy of a lens with respect to a pixel area of the solid-state image sensor dose not deteriorate even if a substrate on which the solid-state image sensor is arranged is deflected or distorted.

  • Patent number: 7456483
    Abstract: A bond portion for bonding the principal plane of a solid-state imaging element with a transparent covering portion and configuring a hollow portion therebetween is provided with: a first opening end portion on the hollow portion side; a second opening end portion on the outer side; and a trap portion. The first opening end portion, the trap portion and the second opening end portion constitute a vent path. The vent path is shaped not to connect the first opening end portion with the second opening end portion linearly but to connect the opening end portions in the bond portion via the trap portion larger than the opening end portions.

  • Patent number: 7397023
    Abstract: An optical path delimiter having a lens is disposed so as to be in contact with a transparent lid bonded to a surface of a solid-state image sensor, and is fixed without bonded. Further, the solid-state image sensor to which the transparent lid is bonded, the optical path delimiter disposed so as to be in contact with the transparent lid without bonded, a DSP serving as a signal processor, a circuit part and a wiring board are fixed by being sealed in a synthetic resin. Even when distortion occurs due to warpage, flexure or the like on a board where the solid-state image sensor is disposed, the accuracy of the alignment of the lens with respect to the solid-state image sensor never decreases. In addition, the solid-state image sensor or the signal processor is never damaged by an external shock.

  • Patent number: 7294828
    Abstract: A screw portion is provided on an image sensing unit, a screw hole portion to be engaged with the screw portion is provided on an optical path delimiter, and the screw portion and the screw hole portion are engaged together to thereby fix the image sensing unit and the optical path delimiter so that a lens barrel of the optical path delimiter is in contact with a transparent lid bonded to a surface of a solid-state image sensor. The solid-state image sensor, the transparent lid, a DSP, a wiring board and the like are sealed by a sealing portion made of a resin. Even when distortion occurs due to warpage, flexure or the like on the board where the solid-state image sensor is disposed, the accuracy of the positioning of the lens with respect to a pixel area of the solid-state image sensor is never decreased, it can be prevented that the solid-state image sensor or a signal processor is damaged by an external shock, and the optical device module is easily fabricated.
