<p><P>PROBLEM TO BE SOLVED: To provide an optical pointing device which can reduce influence of stray light on image data imaged by an imaging element without having a new shielding wall, and an electronic apparatus having the optical pointing device. <P>SOLUTION: An optical pointing device 30 comprises: a light source 16 for radiating light on a contact surface 11 of a subject 10; an imaging reflector 14 for focusing scattered light from the subject 10 onto an imaging element 15; and a structure S1 which is provided in an outer peripheral region of the imaging reflector 14 and within the range where direct light from the light source 16, scattered light from the subject 10, and other disturbance light can reach, and which prevents light reflected at the outer peripheral region or light transmitted through the outer peripheral region from being incident on the imaging element 15 as noise light. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
