Abstract: A book binding apparatus is provided with a conveyor belt 5 having a book block conveyance surface 13 extending obliquely downward toward a pair of clamp plates 3 and 4 of a clamper 2 at a book block supply position A. A guide plate 21 is attached to the clamp plate 4 on the conveyor belt side and can swing between a standing position and a tilted position. When the pair of clamp plates is placed in a closed position, the guide plate is held in the standing position. When the pair of clamp plates is placed in an open position at the book block supply position, the guide plate swings from the standing position to the tilted position and connects to the book block conveyance surface.
