PROBLEM TO BE SOLVED: To prevent the increase in the size and the cost of a device for stacking long printing plates. SOLUTION: In this stacker 10, a hook 62 of an inclined part 28 supports a tip of the printing plate 12 and moved downward by driving a drive shaft 72 in the direction of an arrow D by a motor 70, and the printing plate is delivered to a receiving plate 38 and held by the inclined surface. Then, the motor is driven in the reverse direction, the drive shaft is rotated in the direction of an arrow E to turn an upper guide 32 by a first link mechanism 92, to open a lower guide 30, and to turn the inclined part 28 toward a stock part 24. Even when the printing plate is so long as to stretch over a curved guide part 26 and the inclined part, the printing plates can be reliably tilted and stacked in the stock part by one motor without increasing the output torque of the motor.
