Abstract
The present disclosure relates to a scanner and an electronic apparatus including the scanner. The scanner according to the present disclosure comprises a mirror, a substrate separated from the outside of the mirror, a first and a second mirror support member, a first and a second mirror spring, and a plurality of combs formed on the substrate and to supply a rotational force based on electrostatic force to the mirror, wherein the substrate includes a first edge and a second edge closer to the mirror than the first edge and placed at a lower position than the first edge, and the optical interference angle at the second edge is greater than the optical interference angle at the first edge. Accordingly, it is possible to output light in both directions of a mirror and thereby to perform wide-angle scanning.
