1. An apparatus for singling value documents, comprising:
a support means; a conveyor belt for picking a single value document from a stack of value documents lying on the support means, at least a portion of the conveyor belt being movable back and forth relative to the support means between a first position and a second position, wherein the conveyor belt in the first position cannot touch the stack lying on the support means, and the conveyor belt in the second position can touch the lowermost value document of the stack lying on the support means, and thereby can pick the value document from the stack at least partially; a positioning device in direct contact with the conveyer belt, the positioning device moving the conveyor belt between the first and second positions; and a compensating element in direct contact with the conveyor belt, the compensating element moving the conveyor belt to compensate for changes in lengths of portions of the conveyor belt that occur when positioning the conveyor belt, the compensation of the compensating element reducing mechanical stress of the conveyor belt to a minimum, the compensating element being coupled to the positioning device such that movement of the positioning device to move the conveyor belt from the first position to the second position causes a synchronous counter-movement, opposite to the movement direction of the positioning device, of the compensating element to move the conveyor belt and reduce mechanical stress of the conveyor belt; wherein the positioning device comprises a first diverting element configured to divert the conveyor belt such that substantially linearly extending portions of the conveyor belt adopt different angles on the two sides of the diverting element. |
