Abstract
The present invention discloses a short-range light source device for use with an image pick-up apparatus and the image pick-up apparatus provided with the same. The short-range light source device comprises a fixing base, multiple protective cap units, multiple light source units and multiple driving units. The fixing base constitutes a light receiving pathway corresponding to the lens of the image pick-up apparatus. Upon being driven by the driving units, the protective cap units are pivotally rotated in relation to the fixing base between a protective shielding position and an open position in a synchronous manner. Each of the light source units has a light exit face which is shielded and protected when the protective cap units are located at the shielding position and exposed when the protective cap units are located at the open position.
