Transporter and transport method

A transporter comprising:

• a conveyor that conveys an object in a first direction, the conveyor being movable in a second direction, the second direction being different from the first direction;
• a restrainer disposed corresponding to a downstream end of the conveyor in the first direction;
• and
• a restrainer moving unit that keeps, in a case where a position of the conveyor, in the second direction, relative to an object-transporting destination is out of a preset range, the restrainer at a restraining position at which the restrainer restrains a movement of the object, and the restrainer moving unit that starts to move, in a case where the position of the conveyor, in the second direction, relative to the object-transporting destination is in the preset range, the restrainer toward a releasing position at which the restrainer allows the movement of the object,
• wherein
• the restrainer moving unit comprises a first arm, a second arm, and a linkage, the first arm is to be on the object-transporting destination, the second arm is moved by the first arm by coming into contact with the first arm in the case where the position of the conveyor, in the second direction, relative to the object-transporting destination is in the preset range, and the linkage links the second arm to the restrainer.
