A camera prevents a lens barrel from extending accidentally upon receiving, for example, an external impact. A camera includes a barrel having a guide groove extending in X-direction, a lens barrel including an engagement protrusion protruding radially outward and engaged with the guide groove on the barrel, a switch spring extending between a spring engagement portion and the engagement protrusion, a drive lever rotatable about a lever shaft, a stopper rotatable about a stopper shaft in the drive lever, and a stopper urging spring urging the stopper. The drive lever includes a pusher that pushes the engagement protrusion in the positive X-direction and a rotation restrictor that restricts rotation of the stopper. The stopper includes a restraint portion that is to be on a path of the engagement protrusion to restrain movement of the engagement protrusion in the positive X-direction when the drive lever is at an initial position.

A variable-power optical system (ZL) is constituted by, in order from the object side and along the optical axis, the following: a first lens group (G1) that has a positive refractive power; a second lens group (G2); a third lens group (G3) that has a negative refractive power; and a rear group (GR) that includes a plurality of lens groups. When power is varied from the wide-angle end to the telephoto end, the interval between the first lens group and the second lens group increases, the interval between the second lens group and the third lens group increases, and the interval between the third lens group and a lens group in the rear group positioned closest to the object decreases, thus satisfying the following conditional equation:

0.10<D1/D2<1.80, where D1 is the length on the optical axis from the lens plane closest to the object of the first lens group to the lens plane closest to the image, and D2 is the length on the optical axis from the lens plane closest to the object of the second lens group to the lens plane closest to the image.

The G2 carrier may be positioned by a lens transporter within the G13 carrier at a particular zoom factor to form a lens pair to enable optical investigation and/or transporting of the lens pair.

The proposed invention relates to a camera module with an optical image stabilization function. A flexible printed circuit board (FPCB) electrically connected to an image sensor is implemented to serve as an electrical path and at the same time, serve to provide an elastic restoring force in directions of a plurality of axes, thereby further miniaturizing and lightening the camera module.

The present disclosure describes a projector which has: an image projection portion; an image provision portion that provides a projection image to the image projection portion; a deviation movement detection portion that detects a deviation movement of the image projection portion; and an image process portion that based on detection by the deviation movement detection portion, shifts the image provided by the image provision portion in a direction where the deviation movement is corrected. According to this, even if an image projection function does not include a deviation correction function, it is possible to perform the deviation correction by means of the image process.
