Imaging apparatus including multiple optical systems
View Patent ↗The number of drive motors in a digital camera having multiple imaging optical systems is curtailed. The digital camera has a first imaging optical system and a second imaging optical system. The first imaging optical system has a zoom lens group and a focus lens. The second imaging optical system has another zoom lens group and another focus lens. The focus lens groups are actuated commonly by a focusing drive motor. The former focus lens group is moved by a gear G 3 and an outer peripheral gear of a lens guide ring. The latter focus lens group is moved by a feed screw.
1. An imaging apparatus having multiple optical systems, comprising:
a first imaging optical system; and
a second imaging optical system having an aperture of angle which differs from that of the first imaging optical system, wherein
the first imaging optical system has a first lens for focusing;
the second imaging optical system has a second lens for focusing;
the first lens and the second lens are driven by a common focusing drive motor;
the first lens meshes with an inner peripheral thread formed on a lens ring guide rotationally driven by the focusing drive motor; and
the second lens is connected to a feed screw coupled to the focusing drive motor.
2. The imaging apparatus having multiple optical systems according to claim 1 , wherein a gear is formed on an outer periphery of the lens guide ring, and meshes with the focusing drive motor.
3. The imaging apparatus having multiple optical systems according to claim 2 , wherein an angle of view of the second imaging optical system is set so as to become smaller than an angle of view of the first imaging optical system; and
a distance over which the first lens travels is set so as to become smaller than a distance over which the second lens travels.
