1. A medical couch apparatus, comprising:
a couch body;
a top, on which a subject is mounted;
a frame arranged between the couch body and the top to be guided in the rostrocaudal direction of the subject by the couch body;
a driving unit configured to transfer the top in the rostrocaudal direction via the frame;
a guide unit arranged between the frame and the top and configured to guide the top in the rostrocaudal direction;
a biasing mechanism configured to bias the top in an opposite direction of a transfer direction of the transfer of the top; and
a bias control unit configured to apply a force to the top to be transferred in the opposite direction for the frame through the bias applied by the biasing mechanism when the transfer of the top by the driving unit is stopped, wherein
the biasing mechanism comprises:
a transferring member configured to engage with the top such that the transferring member transfers in the direction orthogonal to the rostrocaudal direction;
a link member having a center part that is axially supported by the frame rotatably and at opposite ends, the link member configured to guide the transferring member in a reciprocable manner between the opposite ends;
a bias member configured to bias the top via the transferring member by biasing the link member in a specific rotational direction; and
a switch unit configured to bias the top in the opposite direction by
transferring the transferring member to one of the opposite ends of the link member when the top is transferred in one direction along the rostrocaudal direction, and
transferring the transferring member to another end of the opposite ends of the link member when the top is transferred in a direction opposite the one direction.
