Patent ID: 7016100

Claim:
An electronic instrument having a mirror device comprising: a mirror substrate having a mirror and a support substrate that supports the mirror substrate, a wherein the mirror substrate includes: a plurality of first mirror-side operating regions that are driven by a predetermined distance-dependent driving force; a plurality of second mirror-side operating regions that are driven by the distance-dependent driving force and function as the mirror, and hinges disposed on respective ends of each of the second mirror-side operating regions, one hinge being connected to one of the first mirror-side operating regions and an other hinge being connected to an other one of the first mirror-side operating regions, wherein the support substrate includes: a plurality of first opposite-side operating sections, the distance-dependent driving force acting between each one of the first opposite-side operating sections and a corresponding one of the first mirror-side operating regions; and a plurality of second opposite-side operating sections, the distance-dependent driving force acting between each one of the second opposite-side operating sections and a corresponding one of the second mirror-side operating regions, wherein the first and second mirror-side operating regions and the first and second opposite-side operating sections are formed so that an attractive force is generated as at least part of the distance-dependent driving force, wherein at least one of the mirror substrate and the support substrate is formed so that a gap between each one of the first mirror-side operating regions and a corresponding one of the first opposite-side operating sections is narrower than a gap between each one of the second mirror-side operating regions and a corresponding one of the second opposite-side operating sections, and wherein the first opposite-side operating sections are arranged in a direction of the hinges and the second opposite-side operating sections are arranged in a direction intersecting the direction of the hinges.
