    摘要: An autonomous traveling device includes a vehicle body, a traveling body to move the vehicle body, a ranging device to consecutively change a direction of emission of light beams while optically scanning a scanning range, and a reflection body to change a direction of an optical path of at least part of light beams emitted from the ranging device and reflected to an area other than a center area of the scanning range. Further, an autonomous traveling device includes an optical path changing device. The optical path changing device changes an angle of inclination downwardly relative to a scanning plane of the ranging device and changes a direction of an incident light from a lateral direction to a forward direction of the vehicle body. Further, the optical path changing device changes a direction of an incident light toward a foot area of the vehicle body.

    摘要: An optical scanner includes a light source, an optical element, a deflector, a casing, and a first cover. The deflector deflects the light beam emitted from the light source to scan a photoreceptor through the optical element. The casing includes an upper opening, walls including a transparent plate defining a deflector compartment to accommodate the deflector, and an optical element mounting portion to accommodate the light source and the optical element. The first cover covers the upper opening of the casing and includes a recessed portion recessed toward the bottom of the casing and including a first opening at the bottom thereof facing the deflector. The recessed portion and the walls are directly or indirectly connected to define a single continuous space isolating the deflector compartment from the optical element mounting portion. The recessed portion and the deflector compartment communicate via the first opening.

    摘要: An optical scanner includes a light source for projecting a light beam against a target, a deflector for deflecting the light beam, a coupling lens, an optical element, a light source support member, and a housing. The coupling lens directs the light beam to the deflector. The optical element focuses the light beam deflected by the deflector into a desired shape. The light source support member supports the light source. The housing houses the light source supported by the light source support member, the deflector, and the optical elements. The housing includes at least two coupling lens mounts on which the coupling lens is fixed on an optical path between the light source and the target, and accommodates multiple light source support members. The coupling lens is fixed to the coupling lens mount using an adhesive agent after an optical axis of the light beam is aligned.

    摘要: A curvature correction device used in an optical scanning unit includes a holder and a pushing unit. The optical scanning unit includes a light beam emitter to emit a light beam, a deflection unit to deflect the light beam in a main scanning direction, and a reflection mirror to reflect the light beam. In at least one embodiment, the curvature correction device includes a holder and a pushing unit. The holder holds the reflection mirror in a state in which the reflection mirror is forcibly bent in a first direction. The pushing unit pushes the reflection mirror held by the holder to bend the reflection mirror in a second direction opposite the first direction. The curvature correction device corrects the curvature of the main scanning line by adjusting an amount at which the pushing unit pushes the reflection mirror. The holder has a stiffness larger than the reflection mirror.
