<p>PROBLEM TO BE SOLVED: To attach/detach a roller used for carrying a paper sheet easily and safely without the disassembly of respective parts. SOLUTION: A roller 8 is installed so as to be put in or taken out freely and a drive shaft B9 combined by a turning stop is supported in a cantilever state and its free end 23 is extended upto a part beyond the maximum paper passing width PWMAX of a paper passing passage 6. A holding part 27 extended to near its free end 23 along the drive shaft B9 is fixed to the end surface of the roller 8 so as to hold this holding part 27 and attach/detach the roller 8 to the drive shaft B9. The falling off of the roller 8 combined by a turning stop to the drive shaft B9 is stopped by a falling off stop mechanism 31 and the falling off of the roller 8 can be released by an operation near the free end 23 of the drive shaft B9. Thereby, the roller 8 can be attached/detached only near the free end 23 of the drive shaft B9 with a wide space without the arrangement of the other parts and the easiness and safety of the work can be improved.</p> |
