<p>PROBLEM TO BE SOLVED: To suck all sizes of glass bases, etc., by forming the surface of a suction disc being brought into contact with a member to be coated of a porous body in an apparatus wherein coating is performed by moving relatively the member to be coated being vacuum-sucked on the suction disc and a coating head for coating the member to be coated with a coating liq. SOLUTION: In a die coater which is a coating apparatus applied for preparing a color filter for color liq. crystal display, a pair of guide channel rails 4 are formed on a base 2 and a table 6 as a suction disc is freely reciprocatingly movably mounted through a pair of slide legs 8. In addition, the top face of the table 6 is formed as a porous suction face. I.e., the table 6 consists of a porous body forming a suction face and a holding plate for supporting the porous body and four pieces of lift pins for elevating/lowering the base plate are assembled. In this case, the porous body is set so as to make the aperture ratio in the range of 1-20% and it is formed in such a way that the aperture of the porous body becomes a hole with the diameter of at most 0.5 mm.</p> |
