PURPOSE:To reduce the size of a direction changing section of a receiving table, by making an arm for pivoting/suspending the receiving table horizontally telescopable and moving the arm while engaging the upper/lower and front/rear positions thereof with an arm guide in a linear path. CONSTITUTION:A plurality of longitudinally telescopable arms 5 are projected from a chain 3 and a receiving table 7 is suspended at the tip thereof. An arm guide 6 to be engaged with a guide roller 5-1 fixed to the arm 5 is a rectangular track constituted of upper/lower and front/rear linear paths and circular corner tracks. A receiving table attitude holding guide 8 is provided in parallel with the arm guide 6. The arm 5 comprises a fixed section 5a and a telescopable section 5b, and when the chain 3 rotates, the fixed section 5a rotates around the center of a sprocket 2 and the guide roller 5-1 at the tip of the telescopable section 5b engages with the guide 6 and guided then rolls while extending the telescopable section 5b.
