To provide a hot air circulation auto rack dryer in which the printing quality of printed matters is prevented from being lowered by making constant the rotating angle of a leaf when it is tilted within a predetermined angle range by the moving of the center of gravity of the leaf itself by its own weight while the leaf is moved from the attitude vertical to the installation surface of the dryer in the reversal direction to prevent the printed matters from being deformed.
This hot air circulation auto rack dryer comprises a rotating angle control means 1 for making constant the rotating angle of the leaf when it is tilted within a predetermined angle range by the movement of the center of gravity of the leaf itself by its own weight while the leaf 51 is moved from the attitude vertical to the installation surface of the dryer in the reversal direction.
