１４によって巻取るといった方法が採用されていた。Structure of the conventional example and its problems In the conventional coating apparatus, as the specific structure is shown in Figs. In order to prevent this, while the printed circuit board 2 is being conveyed by the intermittent supply device 3, the adhesive tapes 6 and 7 sent out from the supply devices 4 and 6 are applied continuously via the roll 8, and the coping liquid is applied. Spraying is performed by forming a protective film 10 on the printed circuit board 2 using a device (for example, a spray gun) 9, and then using a curing furnace 11.
The protective film 10 is cured by being passed through a recovery device 13. The adhesive tape 6.7 is peeled off via the roll 12.
A method of winding it up by 14 was adopted.

があった。However, in the above method, the cost increases because the adhesive tape 6.7 is expensive, and the adhesive tape 6.7 has a narrow width that matches the width of the masking part in the direction perpendicular to the supply direction of the material to be coated. Therefore, when peeling off the printed circuit board 2, the adhesive tape 6.7 may be cut, making process quality control difficult.

以下本発明の一実施例について第５〜６図にもとづいて
説明する。Structure of the Invention The present invention provides a paper supply device and recovery device for supplying a coating liquid to a material to be coated, a guide roll for guiding the traveling of the masking paper, a wedge-shaped block for bending the masking paper into an acute angle, and the wedge-shaped block. It consists of a device that presses the material to be coated through masking paper and a device that supplies the material to be coated intermittently. A masking paper with a width greater than its length is supplied, and is bent into an acute angle with a wedge-shaped block to form a line.For pressing, the material to be coated is raised by a device and the boundary line of the masked area and the wedge-shaped By aligning and holding the block with the line formed by the masking paper, the coating liquid is sprayed after protecting the masked area from infiltration. The structure is repeated in that the masking paper is lowered and separated from the masking paper, and then the masking paper is rolled up several millimeters by a recovery device, which allows the use of inexpensive paper, resulting in a significant improvement in cost. DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 5 and 6. Since paper breaks do not occur, there is no need for process quality control.
