摘要： A mirror drive portion which causes a mirror portion to swing around a predetermined swing axis; a single optical sensor including a single light emission portion and a single light reception portion which receives light emitted from the light emission portion; a light blocking portion which is arranged in the mirror portion to swing together with the swing of the mirror portion and periodically blocks the light emitted from the light emission portion along with the swing; and a mirror control portion which controls the swing of the mirror portion based on an alternating voltage and a detection signal of the optical sensor, wherein the mirror control portion acquires a state of the swing of the mirror portion based on a light reception state of the light reception portion and a zero-cross timing of the alternating voltage, and controls the swing of the mirror portion.

摘要： A spray device includes a holding part, a spray part, and a detection part. The holding part is capable of holding a liquid therein. The spray part atomizes and sprays the liquid held in the holding part. The detection part detects a liquid level of the liquid held in the holding part. The detection part includes a first electrode and a second electrode provided inside the holding part, and an application part. The application part applies a first voltage between the first electrode and the second electrode with the first electrode as an anode and the second electrode as a cathode, and then applies a second voltage between the first electrode and the second electrode with the first electrode as the cathode and the second electrode as the anode.

摘要： Provided is a light projection device, and includes: a light source having plural light emission portions arranged side by side in a predetermined direction; a projection lens; and an optical scanner having a mirror portion which scans light passed through the projection lens in a direction that the light emission portions are aligned, and a drive source swinging the mirror portion. The mirror portion scans a scanning light, which is irradiated from each light emission portion and scanned by the mirror portion, to form an intensity distribution having a central valley part and peaks located on both sides of the valley part. The optical scanner scans the light irradiated from the light emission portions in a manner that at least a peak of an intensity distribution of scanning light of other light emission portion is located in the valley part of the intensity distribution.

摘要： An optical pickup includes a plurality of light sources, an objective lens, a diffractive optical element, and a light-detecting unit. The various light sources emit light of wavelengths that are different from each other. The objective lens focuses light on an optical disc. The diffractive optical element includes a diffracting portion and a light-blocking portion. The diffracting portion diffracts return light reflected from a first recording layer of the optical disc where information is being read or written. The light-blocking portion blocks stray light reflected from a second recording layer of the optical disc that is different from the first recording layer. The light-detecting unit receives the diffracted light of the diffractive optical element and generates an output signal to generate a tracking error signal based on this diffracted light. Furthermore, the light-blocking portion includes a plurality of light-blocking patterns which block light of wavelengths that are different from each other.
