FIELD: physics.
SUBSTANCE: invention relates to the field of equipment for processing valuable documents. Stacker for valuable documents has a stack accumulator and a braking device. Braking device is located along line of valuable documents transportation directly in front of stack accumulator. Brake device has a transport shaft and a brake shaft oriented parallel to it. Corresponding valuable document is transported between the shafts. At least one drive roller is rigidly mounted on the transfer shaft. On the transport shaft there is additionally mounted at least one roller installed with possibility of rotation. Also, at least one cam roller and at least one eccentric roller are mounted on the brake shaft. Due to the rotation of the brake shaft, the eccentric roller is capable of engagement or disengagement with the driving roller lying opposite it. When engaging the rollers, the valuable document is clamped between them. During disengagement valuable document is not clamped between them. Document is braked by clamping between drive roller and eccentric roller.
EFFECT: high speed of processing valuable documents and reduced dimensions of the stacker.
