PURPOSE:To exhaust a skew paper parallel by providing a runner of an elastic body rotatable synchronously to one side roller of the first and the second rollers in the same direction, and making the outer diameter of the runner in a rotation larger than the outer diameter of the roller. CONSTITUTION:A paper exhaust roller device 11 is composed of paper exhaust rollers 31 and 32 contacting each other, and the paper exhaust roller 31 is formed of a shaft 31a and plural roller pieces 31b fixed to the shaft 31a. The paper exhaust roller 32 is formed of a shaft 32a parallel to the shaft 31a and plural roller pieces 32b fixed to the shaft 32a, and the rollers 31 and 32 are provided opposing each other. In the shaft 32, rotary runners 33 are provided to the both sides of the roller pieces 32b, the runners 33 are formed of an elastic material and rotated on the same direction synchronously with the roller 32. The outer diameter of the runner 33 is made larger than the roller 32. As a result, although a bending is generated when a recording paper 35 is fed in a skew condition, the bending is eliminated by the runners 33, and as a result, the recording paper 35 is pushed out parallel at the time when it goes out of the runners 33. |
