As described above, the invention according to claim 6 is, in the invention according to claim 1, 2, 3, 4 or 5, the value of the sheet conveyed in the sheet conveying path is set to the inner side of the arc-shaped conveying guide. Since the displacement detection sensor for detecting the above displacement is provided and the air volume of the air blowing mechanism is reduced or set to “0” based on the detection result from the displacement detection sensor,
When the displacement detection sensor detects that the paper is displaced toward the inner arc-shaped conveyance guide side by the set value or more due to the wind from the air blow hole because the paper is weak, the air volume of the air blowing mechanism decreases or becomes “0”, It is possible to prevent the sliding contact noise from being generated due to the sliding contact with the inner arc-shaped conveyance guide.
