  • Patent number: 9320161
    Abstract: A first drive arm and a second drive arm are rotatably coupled. A tip portion of the first drive arm and a device main body are connected to each other through a first connection link, and a tip portion of a second drive arm and the device main body are connected to each other through a second connection link. Because each of the drive arms and the device main body are connected to each other through an axial rotational portion, the device main body is moves smoothly between an extended position and a retracted position, and vibration and rattling are suppressed.

  • Patent number: 9036336
    Abstract: An in-vehicle display apparatus includes a display panel including a rectangular display screen; a pair of semicircular decorative rings (frames) obtained by dividing an annular member into two parts along a line extending in a lateral direction of the display screen; and a driving mechanism that drives the decorative rings to reciprocate toward and away from each other in a longitudinal direction of the display screen. The decorative rings are rotatable around axes extending in the lateral direction of the display screen. The driving mechanism moves the decorative rings while the decorative rings are in front of the display panel and in parallel positions in relation to the display screen. The decorative rings are rotated on sides of the display panel in a longitudinal direction of the display panel and stored in storage spaces.

  • Patent number: 8649161
    Abstract: An on-vehicle display apparatus includes a motor, a gear train, a threaded rod, a slider screwed to the threaded rod, and a display main body rotatably connected to the slider. The lead angle of the threaded rod is set greater than the friction angle thereof. The gear train includes first and second gears facing each other. Protrusions provided on one of the first and second gears are fitted in recesses provided in the other. A spring member elastically urges the first gear toward the second gear. A detection sensor detects the size of an external force on the basis of the displacement of the first gear against the spring member in the axial direction. The motor is controlled on the basis of the detection result of the detection sensor such that the display main body is moved away from the external force.
