Abstract: A cabinet is formed on the top face with an entry opening for rolled paper, and a storage section for accommodating the rolled paper. A cover is provided for opening/closing the entry opening, and the upper front of the cover is provided as a slipsheet entry face for inserting a slipsheet. The slipsheet entry face is formed in one side margin with a slipsheet guide along the insertion direction of the slipsheet. A paper discharge slot of the rolled paper is formed by a gap between a buff portion of the cabinet and the tip of the cover, when the cover is closed. The paper discharge slot is at a position lower than that of the slipsheet entry face. A slipsheet print section is placed on the upper rear portion of the cover.
