PURPOSE:To permit a decrease in useless waste of ink without a possible staining of the interior of a printer by preventing a large accumulation of printing ink which was scraped at the edges of side boards through tilting in a direction to gradually come close to the tip of a squeezee roller. CONSTITUTION:A portion of printing ink at an ink staying place 12 enters between an inner side surface 1a of a side board 1 and a tip surface of a squeezee roller 2 and adheres to the tip surface of squeezee roller, forming a thin layer. A portion of the printing ink is scraped off by an edge portion when it passes the peripheral edge 17a of a concave 17 and it adheres to the tilted surface 17b of the concave 17 and stays in the wedge shaped opening which is formed by the tilted surface 17b and the tip surface of the roller 2, and it is given a force in the direction of the rotation by rotation of the roller 2 and passes the peripheral edge 17a and is carried away by being swallowed between the inner side surface 1a of the side board 1 and the tip surface of the roller 2, resulting in no large amount of accumulation of printing ink in the opening. Therefore, the dropping from the side board 1 of the printing ink which was scraped off from the tip edge of the roller 2 is avoided. |
