Lens driving device, camera device and electronic apparatus
A lens driving device includes: a box-shaped lens carrier for fixing a lens barrel to the inside thereof which lens barrel is for guiding light from an imaging target to a photo detecting sensor, wherein the lens carrier has a first opening through which light from the imaging target enters, a second opening through which light toward the photo detecting sensor exits, and a third opening for mounting the lens barrel, wherein the third opening is formed between ends of two opposing side walls of the box-shaped lens carrier other than side walls being formed with the first opening and the second opening, wherein inner surfaces of the two opposing side walls are formed in parallel with respect to each other from the third opening to the center of the lens carrier.
Lens apparatus and image pickup apparatus
A lens apparatus includes an optical element, first and second fixed barrels coupled to each other, a conversion mechanism from a rotary motion to a linear motion, fitted to the first fixed barrel and configured to be rotated about a first axis as an axis of the first fixed barrel to drive the optical element along the first axis, an operation member fitted to an outer periphery of the second fixed barrel and configured to be operated to be rotated about a second axis as an axis of the second fixed barrel, and a transmission ring, supported by the conversion mechanism to be translatable in a first direction orthogonal to the first axis and by the operation member to be translatable in a second direction and orthogonal to the second axis, configured to transmit rotation from the operation member to the conversion mechanism.
Voice coil motor
A VCM (voice coil motor) is disclosed, the VCM including: a rotor including a cylindrical bobbin for accommodating a lens and protruded at a bottom end with a boss, and a coil block arranged at a periphery of the bobbin; a stator including a magnet facing the coil block and a yoke fixing the magnet; and an elastic member including a first elastic member formed with a through hole coupled to the boss of the bobbin and a second elastic member coupled to an upper end facing the bottom end of the bobbin; wherein the boss is formed with a disengagement prevention unit inhibiting the first elastic member from being disengaged from the boss, and the first elastic member is formed with a coupling unit contacting a joint where the disengagement prevention unit and the coupling unit meet.
