PURPOSE:To automatically adjust both roller groups so as to be positioned opposite to each other at a distance suitable to the thickness of the paper by shifting a 2nd roller group in a direction for separating the 2nd roller group from a 1st roller group when the paper is loosened. CONSTITUTION:The 1st roller group 3110 formed on a 1st supporting shaft 311 for a loosening part 310 is constituted of alternately fixed large-diameter roller 311a and small-diameter roller 311b, and the 1st roller group 3120 formed on the 2nd supporting shaft 312 is constituted of alternately fixed large-diameter roller 312a and small-diameter roller 312b. And also, as for a counter distance adjusting part 350, the counter distance with the 1st supporting shaft 311 can be adjusted by shifting the 2nd supporting shaft 312 in a radial direction. Besides, an approach quantity controlling part for variably controlling the closest distance of the 2nd supporting shaft 312 to the 1st supporting shaft 311 is constituted of a front panel part 331 for a fixing holder 330, a cross-shaped screw 340 and an erected piece 325 for a shaft holder 320. |
