摘要:
The present invention provides a paper seasoning apparatus and an inkjet recording apparatus including a paper seasoning apparatus, capable of seasoning paper configured in a paper stack, and separating the paper stacks by introducing separation plates between sheets of the paper. Namely, separation plates for separating paper into specific numbers of sheets are introduced from a plate feeding apparatus into a housing of a paper seasoning apparatus. A separation plate lowering device lowers the separation plate that is supporting a paper stack. Seasoning is performed by blowing air from an air blowing device against the paper stack.
