Abstract

PURPOSE:To obtain a stable pushing and storing operation by energizing a link member toward a direction for reducing an interval between sheets and providing a spring for pushing and energizing a retaining board toward guide rails. CONSTITUTION:Paper notes T transferred to the predetermined position via conveyor belts 2 and 3 are pushed and inserted in a storage magazine 6 with a pushing member 8 via an opening 7. In this case, a retaining board 9 is pushed downward with the pushing member B against the resilient force of a spring 24. And when the pushing member 8 has moved upward to the original position thereof, the paper notes T pushed thereby into the storage magazine 6 are clamped between the retaining board 9 and the lower sides of guide rails 4 and 5. On the other hand, where the number of the paper notes T clamped between the retaining board 9 and the lower sides of the guide rails 4 and 5 is large, the displacement of the spring 24 becomes large, thereby giving a large effective force. As an angle between the direction of the force and a link member 15 becomes small, however, the link member 15 is subjected to less moment and a small pushing force is required for the pushing member to push the paper notes T into the storage magazine 6.
