An imaging apparatus that is easily moved between locations protects an imaging element in motion and provides a first arm member and a proximate movable second arm member. A lighting-imaging element is movably positionable proximate an arm mechanism and also proximate a rear-side location of a wheeled platform relative to a traveling direction thereby preventing damage. The first and second arm are relatively surrounded with a sub-arm and lighting-imaging element, thereby preventing further unintended movement. Accordingly, an elongating (separation) of the first and second arm members are prevented.
