PROBLEM TO BE SOLVED: To increase a posture stability of a movable body separately at a standby position and a movable position by using a magnet.SOLUTION: An upper movable presentation device includes: a movable body 61 for reciprocating between a standby position and a movable position in conjunction with the driving of a drive motor 150; a magnet 75 provided in the movable body 61; a first sheet metal member 93 which is provided in a device body 80 relatively displacing its position with respect to the movable body 61 in conjunction with the reciprocating movement of the movable body 61, and to which the magnet 75 magnetically attaches when the movable body 61 is at a standby position; and a second sheet metal member 133 which is provided in a support arm 121 relatively displacing its position with respect to the movable body 61 in conjunction with the reciprocating movement of the movable body 61, and to which the magnet 75 magnetically attaches when the movable body 61 is at a movable position. Since the one piece of magnet 75 provided in the movable body 61 magnetically attaches to the first sheet metal member 93 and the second sheet metal member 133 respectively, the movable body 61 is supported at both standby position and movable position in conjunction with the reciprocating movement. |
