Claim:
A conveyance method for a processing step wherein, when a movable body is caused to move along a processing line in which processing liquid tanks are disposed at prescribed positions, a supporting body is raised and lowered by means of a swinging link mechanism provided swingably in the upward and downward directions about a support axle on the movable body, and a conveyed object supported on the supporting body is introduced into a processing liquid in a processing liquid tank and the conveyed object is thereby processed; in the swinging link mechanism, a first arm supported rotatably in the upward and downward direction on the support axle is caused to rotate in the upward and downward direction, in addition to which a second arm supported rotatably on the free end section of the first arm is rotated by means of a third arm coupled to the movable body and a prescribed position of the second arm, and the supporting body provided on the free end section of the second arm is raised and lowered following a movement path that traces a substantially vertical direction, thereby introducing same into, and removing same from, the processing liquid in the processing liquid tank.
