<p>PURPOSE:To prevent recording papers from loosening when a punch pin is removed by constructing a recording paper processing unit so that punch pins in a puncher are removed after the recording papers are binded. CONSTITUTION:After two binders 60 moved in the direction of a puncher 50, binder drive motors M9, M10 start rotation. Consequently, a lever 65 rotates to lower a push down chip 67 so as to lower a thin board 68 thus separating only one binding metal in a cartridge 70 and biting it into a copying material. Then a punch drive motor M6 starts rotation to cause rotation of two eccentric blocks 54a, 54b, but since they are secured under a positional relation shifted by some rotary angle each other, punching work of punch pins 56a, 56b through rolling chips 55a, 55b is also shifted in time. When punching work is shifted in time from binding work in such a manner, the punch pins 56a, 56b can be removed easily from copy paper so as to prevent loosening of copy papers.</p> |
