Abstract: An embodiment includes: a first transport module on which a carriage moves; a second transport module that is configured to be able to move to a position for connecting to the first transport module and on which the carriage is able to move to and from the first transport module; a position detection unit that detects a position in a moving direction of the second transport module and outputs position information; a first control unit that controls motion of the carriage on the first transport module; a second control unit that controls motion of the carriage on the second transport module; a third control unit that controls motion of the second transport module; and a fourth control unit that controls the first to third control units. The fourth control unit corrects a position where the second transport module connects to the first transport module based on the position information.

Abstract: A vehicle headlamp apparatus is provided. The vehicle headlamp apparatus includes a first lamp configured to selectively produce a first high beam light distribution pattern and an infrared light distribution pattern, a second lamp configured to selectively produce a second high beam light distribution pattern and a low beam light distribution pattern, a vehicle detector which detects a vehicle running ahead, and a condition-dependent selection controller which controls the first and second lamps. The condition-dependent selection controller controls the second lamp to produce the low beam light distribution pattern when the vehicle detector detects a vehicle and to produce the second high beam light distribution pattern when the vehicle detector detects no vehicle. The condition-dependent selection controller controls the first lamp to produce the infrared light distribution pattern, irrespective of whether the vehicle detector detects a vehicle.

Abstract: A leveling device helps to prevent misalignment in the axial direction of an adjusting screw with respect to a shaft. A shaft 20 has an insertion cylindrical portion 21 that is in a generally cylindrical shape, and a shaft-side engagement portion 23 that is connected in the axial direction of the insertion cylindrical portion. An adjusting screw 27 has an insertion shaft portion 28 that mates with the insertion cylindrical portion of the shaft, and a screw-side engagement portion 31 that engages with the shaft-side engagement portion. The insertion shaft portion of the adjusting screw has an irregular portion 28a that is press-fit into the insertion cylindrical portion of the shaft, and that restricts movement in the axial direction with respect to the shaft.

Abstract: A leveling apparatus for a vehicle headlamp has a case body, a motor disposed within the case body, a worm wheel supported by the case body rotatably but unmovably in the longitudinal direction and rotated by the motor and a shaft screwed into the worm wheel. The shaft and the worm wheel are screwed together by thread ridges provided on the inner side of the worm wheel and thread ridges provided on the outer periphery of a driven portion forming the shaft. The thread ridges on one side out of the thread ridges on two sides are formed by one to two pitches.

Abstract: A beam angle adjusting device for a vehicular headlamp having a reduced size, especially a reduced thickness of the case body of the device. The beam angle adjusting device is provided with a case body, a motor disposed inside the case body, and a shaft which moves in the front/rear direction in response to rotation of the motor, wherein the motor and a circuit member which has a terminal for supplying power are arranged in symmetrical positions in relation to a plane containing the shaft.
