Some collating machines have a plurality of sheet feeding stages arranged in the vertical direction, and sequentially take out and collate sheets placed on each sheet feeding stage. FIG. 4 is a schematic side view showing an example of such a collating machine. In FIG. 4, the collating machine 30 has ten paper feed stages 2a to 2j arranged in the vertical direction, and a predetermined number of sheets 3a to 3j are placed on each paper feed stage. Paper feed rollers 4a to 4j are provided at the front end of each paper feed stage. Reference numerals 5a to 5j denote sheet feeding units, 6a to 6j and 7a to 7j denote longitudinal conveyance rollers, and 8a to 8i denote transmission rollers.
[0003]
Reference numeral 9 denotes a drive motor which rotates a pulley 10 around which a chain or the like is wound, and rotates the vertical conveying rollers 6a to 6j via power transmission means (not shown). -The vertical transport rollers 7a to 7j are rotated via the rollers 8a to 8i. The paper 3a placed on the paper feed stage 2a is pulled out by the paper feed roller 4a and transported in the vertical direction by the vertical transport rollers 6a and 7a through the paper feed unit 5a. In the same manner, the paper fed from each paper feed stage is transported to the vertical transport roller, sequentially stacked on the paper 3a, and transported in the vertical direction while being collated. The sheet bundle collated in this way is discharged from the first discharge unit 13 to the outside.
