Abstract: A head-up display device includes an image display device that outputs display light of an image; a mirror having a reflecting surface that reflects the display light toward a reflecting portion, and an input shaft; a motor that has an output shaft located on an extended line of the input shaft, and rotates the output shaft; a transmission member that has a cylindrical fitting portion to which the input shaft is press-fitted and a coupling portion coupled with the output shaft and transmitting output torque of the motor from the output shaft to the input shaft; a holding member that holds the motor; and a first spring that is interposed between the holding member and the transmission member, and imparts, to the transmission member, a biasing force oriented to bring the mirror close to the output shaft.

Abstract: A board design assistance device includes a design data acquirer to acquire design data for a printed circuit board, a first determiner to determine, based on the design data for the printed circuit board, whether a lengthwise direction of board fiber in the printed circuit board is perpendicular to a longitudinal direction of an electronic component mounted on the printed circuit board, a second determiner to determine, based on the design data for the printed circuit board, whether a wire is routed crosswise from a pad receiving the electronic component mounted on the printed circuit board, and a notifier to provide a notification including error information specifying an electronic component determined to have a longitudinal direction not perpendicular to the lengthwise direction of the board fiber and determined to be connected to a pad from which a wire is not routed crosswise.

Abstract: A projection device includes a housing including a wall part including an opening, and a cover with a plate shape having a light-transmitting property and closing the opening. The wall part includes a pair of edge parts facing each other with the opening therebetween and extending along a first direction, and a plurality of claw parts disposed at each of the pair of edge parts. The pair of edge parts is curved to the inside of the housing. The cover includes through holes disposed correspondingly to the claw parts. The claw part includes a base part protruding from the corresponding edge part and a holding part protruding from the base part along the first direction. The housing sandwiches and holds the cover between an edge part and the holding parts inserted into the through holes in a state where the cover is curved.

Abstract: A head-up display device includes a housing, a reflecting member, a projection light emitting unit, and a vibration transmitting member. The housing is fixed to a vehicle. The reflecting member is rotatably supported by the housing and is held at a rotation position. The projection light emitting unit projects projection light corresponding to information onto a window of the vehicle through the reflecting member. The vibration transmitting member is provided between the housing and the reflecting member and has elasticity. The vibration transmitting member is fixed to the housing and makes contact with the reflecting member in an elastically compressed state in an entire rotatable range of the reflecting member.
