Abstract: A scanner has a rotational shaft and at least one reflection surface. The scanner rotates the at least one reflection surface together with the rotational shaft to thereby (i) change a direction of the light beam transmitted from the phototransmitter and incident on the scanner to output a changed light beam in a main scanning direction that is orthogonal to an axial direction of the rotational shaft, and (ii) reflect an arrival light beam arriving from a scanning region to thereby output the light beam to a direction in which the light beam is incident on the scanner. A photoreceiver receives the arrival light beam reflected by the scanner. The photoreceiver includes a received-light deflection mirror that deflects the arrival light beam outputted from the scanner in a second direction different from the first direction, and a light receiving device that receives the arrival light beam deflected by the received-light deflection mirror.

Abstract: A ranging device includes a transmitting section, a receiving section, a housing, a transmissive section, and a heating section. The transmitting section transmits a transmission wave. The receiving section receives a reflection wave caused by reflection of the transmission wave from an object. The housing encloses the transmitting section and the receiving section and has an opening formed for allowing the transmission wave and the reflection wave to pass therethrough. The transmissive section is formed of a material transparent to the transmission wave and the reflection wave, and covers the opening. The heating section includes a mesh of metal having a plurality of mesh openings and is disposed to cover at least a portion of the opening. The heating section generates heat by energising the metal to heat the transmissive section.

Abstract: A vehicle mounting structure for a ranging device includes a ranging device, a bracket, and a shielding plate. The ranging device measures the distance to an object by emitting transmitted waves and detecting reflected waves from the object to which the transmitted wave has been emitted. The bracket attaches the ranging device in a mounting space formed on an outer surface of a vehicle and capable of accommodating the ranging device. The shielding plate covers the mounting space from the outer-surface side of the vehicle with the ranging device attached in the mounting space. The mounting space is provided on at least one of a front surface of the vehicle, a side surface of the vehicle, or a rear surface of the vehicle. The shielding plate forms an opening for introducing into the mounting space traveling wind occurring along with travel of the vehicle.

Abstract: A vehicle-mounted sensor cleaning device cleans a sensing surface of a vehicle-mounted sensor. The vehicle-mounted sensor cleaning device includes a gas nozzle spraying a gas toward the sensing surface, a gas supply device supplying the gas to the gas nozzle, and a control section controlling operation of the gas supply device. A predetermined value is set in the control section, for indicating an abnormal state of detection accuracy of the vehicle-mounted sensor based on detection accuracy information of an object which is obtained from the vehicle-mounted sensor. A gas supply threshold value is also set, for use in operating the gas supply device to direct a supply of the gas toward the sensing surface before the detection accuracy information becomes equal to or lower than the predetermined value. If the detection accuracy information has become lower than the gas supply threshold value, the control section operates the gas supply device.
