  • Camera module, electronic device in which camera module is mounted, and method for manufacturing camera module
    Patent number: 9641732
    Abstract: A plurality of lenses constituting a lens unit (1) are fixed to each other with use of an adhesive (20) applied between the plurality of lenses. The lens unit (1) is incorporated into an actuator (30) through an opening (26) of the actuator (30) and is held inside the actuator (30) so as to face directly an inner wall surface of the actuator (30).

  • LENS DRIVE APPARATUS AND CAMERA MODULE
    Publication number: 20150301305
    Abstract: The present invention makes it possible to more accurately determine a position of an imaging lens with respect to an imaging element at low cost. A lens holder (1) is provided with a holder tapered surface (12), and a base (3) is provided with a holder tapered engaging surface (31). When the lens holder (1) is supported by the base (3), the holder tapered surface (12) and the holder tapered engaging surface (31) engage with each other.

  • LENS DEVICE AND ELECTRONIC APPARATUS
    Publication number: 20130038948
    Abstract: In an image pickup element module, a light blocking plate sandwiched between a first lens and a second lens is provided with fixing holes. The light blocking plate is retained by the second lens by projections from the second lens being inserted into the fixing holes. This prevents the light blocking plate from being displaced due to vibration or impact, thus making it possible to keep the optical characteristics of the image pickup element module satisfactory and provide the image pickup element module inexpensively.
