However, the medium posture at the time of feeding is not constant, and the beginning of the medium 1 in the conveyed state is , It is completely unknown how it is leaning. Therefore, in the conventional technique, when the medium 1 is skewed and conveyed by the conveyor belt 2 in the direction A on the conveyor path 4, the medium 1 is conveyed to the belts 2 and 5 until it reaches the next conveyor belt 5.
A pair of medium receiving means 4 rotating at a low speed is provided with a space of a linear distance not restricted by the length of the medium 1 or more.
Skew was corrected by providing a and 4b.
