Abstract:
1. A combiner storage device configured to store a combiner in a housing of a head-up display device, which condenses a display light representing a display image by a combiner having a concave surface to receive the display light, and causes a viewer visually recognize the display image from the concave surface side, comprising: a holder, which is movable with respect to the housing, and holds the combiner; a first connection part, which is rotatable about a first axis that is extended along a horizontal direction as seen from the viewer and immovable with respect to the housing, and whose one end is located in the first axis, and the other end is connected to the holder; and a second connection part, which is rotatable about a second axis that is extended along a horizontal direction as seen from the viewer and immovable with respect to the housing, and whose one end is located in the second axis, and the other end is connected to the holder, wherein the combiner is able to be moved from a projected state projecting from the housing to a stored state being stored in the housing by a four-joint link mechanism assuming that the first connection part is a drive joint driven by a given driving force, the second connection part is a follower joint, the holder is an intermediate joint, and a joint connecting a center of the first axis and a center of the second axis is a fixed joint, an elastic member is provided, which connects at least one of the first connection part, the second connection part, and the holder to a part immovable with respect to the housing, and pulls a connected part by a restoring force, and the combiner is transited from the projected state to the stored state by one of the driving force and the restoring force, and transited from the stored state to the projected state by the other force.
