When the first lock engages and the second lock does not engage the transmission system, the transmission system moves the platform in a first direction according to the rotation of the rotational element. When the first lock does not engage and the second lock engages with the transmission system, the transmission system moves the platform in a second direction other than the first direction according to the rotation of the rotational element.
