PROBLEM TO BE SOLVED: To provide an optical device which achieves miniaturization of optical scanning mechanism and in which reflected light in a light transmission member furnished for protection in front of a light reflection member does not become disturbance. SOLUTION: The light transmission member (a second light transmission member) 2 for protection is furnished in front of a micromirror (a first light reflection member) 1 having a yoke 1d which serves as a light reflection face, a laser beam from a laser light source 11 is reflected on the micromirror 1 via the light transmission member 2, and a photoreceptor 13 is scanned with the reflected light beam via the light transmission member 2. The light transmission member 2 has a function of protecting the micromirror 1 and a function as an optical lens. The number of optical members to be provided at the optical scanning mechanism is decreased by the function as the optical lens of the light transmission member 2, and the photoreceptor 13 is not irradiated with the reflected light B of the laser beam from the laser light source 11 in the light transmission plate 2, and the photoreceptor 13 is irradiated only with the reflected light C in the micromirror 1.

PROBLEM TO BE SOLVED: To provide a micro mirror capable of driving a plurality of micro mirrors in synchronization, a micro mirror device, and a method for driving the micro mirror. SOLUTION: When an AC voltage is applied by a first AC power source 6 to a first electrode, electrostatic forces in the directions opposite to each other are generated between the first electrode 1 (comb tooth section 1d) and second electrode 2 (comb tooth section 2d) and moment is generated in a direction orthogonal to the first electrode 1 and the second electrode 2, and a disk-shaped rotating section 1b rotates around a hinge section 1c as an axis. At this time, the rotating operation of the micro mirror 10 (the rotating section 1b) is controlled by applying the AC voltage of a desired frequency and phase by a second AC power source 8.

PROBLEM TO BE SOLVED: To provide a MEMS mirror scanner structure that can realize high-speed scanning equal to or more than a polygon mirror scanner, that aims for example to realize high precision scanning in use for laser printing, and that is in particular intended to optimize the shape, dimension, etc., of a scanning mirror itself. SOLUTION: The high precision and miniaturization can be attained by necessarily enlarging the range of an optical path that needs more as an angle of incidence becomes lower (smaller). In other words, with the angle of incidence in the range of 25-90° in the direction orthogonal to the target surface of emission, the scanning mirror needs to have a ratio of the length (b) in the direction of the oscillation axis to the length (a) in the direction orthogonal to the axis as (a≥b, a:b=(1.0 to 2.0):1), or (a COPYRIGHT: (C)2006,JPO&NCIPI
