Abstract: An optical scanner includes a substrate having a rigid body and a beam, and a layered body having multiple layers, including a lower conductive layer, a interlayer insulation film and an upper conductive layer, the layered body layered on and protruding outward from the rigid body and the beam. The layered body is patterned to form a resonance scanner portion and a vari-focal mirror, the resonance scanner portion (i) made as a part of the layered body and (ii) having an actuator part, and the vari-focal mirror made as a part of the layered body. The layered body including the resonance scanner portion and the vari-focal mirror is patterned to form a mirror driving wire. In such structure, the size of the optical scanner is reduced, and a frequency change of the resonance scanner portion due to the voltage application to the mirror driving wire is suppressed.

Abstract: A load sensor is constituted by a rib and a vertical transistor including an organic semiconductor film, and a load measurement can be executed based on a change of a gap between a drain electrode and a source electrode which is a channel length of the vertical transistor. Therefore, a change of a current Ids is in a linear relationship to a load applied to the load sensor.

Abstract: A reflector has a reflective surface on first and second directions. Each of torsion beams extends to each opposite side of the reflective surface in the first direction. Each of coupling portions is to each opposite side of the reflector in the first direction and includes a central portion with U-shape having two projection portions and a bottom portion joined to the torsion beam. The projection portions include first concave portions opposing across the torsion beam by being penetrated in thickness direction. Each first concave portion extends in the second direction from an opening to a side surface facing the torsion beam towards an opposite side surface up to a bottom. A distance between the bottoms of the first concave portions across the torsion beam is greater than a distance between the side surfaces each facing the torsion beam of the projection portions.

Abstract: An optical scanning device has a reflecting portion and a supporting body for supporting the reflecting portion. The reflecting portion has a reflecting surface for reflecting light beam. A pair of outside beam members is arranged between the reflecting portion and the supporting body in a longitudinal direction of the device. The device also has a first driving portion, one end of which is connected to the supporting body, while the other end of which is connected to a driving point of the reflecting portion. When the first driving portion is inflected, the reflecting portion is oscillated in a twisting vibration manner at a first axis. The driving point of the reflecting portion is located at a position separated from the first axis.
