摘要

A conventional camera mounted on an information terminal has a focal distance set to 0.3 to ∞m and it has been impossible to set the focal distance to a nearer distance. Especially, a so-called close-up for imaging at a distance of several mm or several cm from an object has been impossible. Moreover, a photographer could not change the camera field angle (i.e., narrow angle and wide angle) or the lens color. To cope with this, the present invention mounts a lens (21) on a camera imaging section (15) by the adhesive force, adsorption force (including suction force and magnetic force), friction force, urging force, and the like.
