A reversing unit includes a fixed plate, a first movable plate provided so as to face one surface of the fixed plate, a second movable plate provided so as to face the other surface of the fixed plate and the rotary actuator. The rotary actuator rotates the first movable plate, the second movable plate and the fixed plate around a horizontal axis. In the reversing unit, a substrate before a back surface cleaning processing is reversed while being held by support pins of the first movable plate and support pins of the fixed plate, and the substrate after the back surface cleaning processing is reversed while being held by support pins of the second movable plate and the support pins of the fixed plate.
