A transport conveyer includes an upstream side conveyer portion and a downstream side conveyer portion. The upstream side conveyer portion is provided such that an upstream side imaginary path line which is circular-arc-shaped is connected to a downstream side imaginary path line such that the tangent line at the downstream side end of the upstream side imaginary path line and the tangent line at the upstream side end of the downstream side imaginary path line are at the same angle. Provided on the upstream side end portion of the downstream side conveyer portion is a rotating operation transport device for supporting and transporting the article such that the amount of rotation of the article by the downstream side conveyer portion is greater than or equal to the amount of rotation caused by the downstream side conveyer portion.
