Abstract:
1. A support device, provided in a movable carrier, for supporting a display device, provided in a cabin top inner surface portion of the movable carrier, configured to move to a view position when being opened from a closed state in a stowage position in the cabin top inner surface portion, the support device comprising: an opening-and-closing mechanism configured to move the display device about a drive shaft from the stowage position to the view position upon receiving a supply of voltage, and to move the display device about the drive shaft from the view position to the stowage position when the supply of voltage to the holding mechanism is stopped; a holding mechanism provided for the drive shaft and configured to hold the display device in the view position with at least two levels of holding force upon receiving a supply of voltage when the display device is moved to the view position by the opening-and-closing mechanism; an acceleration sensor provided in the movable carrier and configured to detect acceleration of the movable carrier; and a control unit configured to (i) control the supply of voltage to the opening-and-closing mechanism to cause the opening-and-closing mechanism to move the display device from the stowage position to the view position, (ii) control, when the acceleration of the movable carrier detected by the acceleration sensor is greater than a threshold value, the supply of voltage to the holding mechanism to cause the holding mechanism to hold the display device in the view position with the higher of the two levels of holding force, and (iii) stop the supply of voltage to the holding mechanism, to cause the opening-and-closing mechanism to move the display device from the view position to the stowage position.
