Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hand proofer for uniformly applying ink or paint on the surface of paper, film, metal or the like.

[0002]

2. Description of the Related Art For example, since ink or paint cannot be accurately discriminated by just seeing the undiluted solution from the outside, it is confirmed that it is applied on the surface of paper or metal. It is necessary to apply the coating with a uniform thickness. Therefore, a hand proofer conventionally used is configured such that an upper roller presses a lower roller by its own weight in a state where each shaft of a pair of rollers is supported by a supporting member via a bearing. .

In another prior art, a blade member which elastically abuts the outer peripheral surface of the lower roller, that is, the roller for applying directly to an object, is provided, and the outer peripheral surface of the roller is provided substantially in the longitudinal direction. Excessive ink or paint that adheres over the entire length is scraped off, and the thickness of the ink or paint in the application area of the roller that contacts the object is made uniform.

[0004]

In such a prior art, since the both ends of the shaft rod of the roller are attached to the supporting member by the bearings, the roller cannot be easily replaced, and therefore, the ink or the paint cannot be replaced. Another hand proofer has to be separately prepared for each different type and color, and the distance between the blade member and the outer peripheral surface of the roller cannot be finely adjusted.

Therefore, an object of the present invention is to make it possible to easily replace the roller so that ink or paint can be applied in a different manner, and to finely adjust the distance of the blade member to the outer peripheral surface of the roller so as to apply it with a uniform thickness. It is to provide a hand proofer that can do.

[0006]

SUMMARY OF THE INVENTION According to the present invention, a substrate and a pair of substantially L-shaped fitting grooves extending substantially vertically from both ends in the longitudinal direction of the substrate are formed on respective inner surfaces facing each other. The support member, a pair of upper and lower rollers in which shaft rods whose both ends are detachably fitted in the fitting grooves of the pair of support members are rotatably inserted, respectively, and the upper roller and the lower roller. The hand proofer is characterized in that it includes a pressing means for pressing toward a substrate and a handle that is provided substantially in the center of the substrate so that the angle with respect to the substrate can be adjusted.

Further, according to the present invention, in the vicinity of either one of the pair of rollers, the one roller is close to the other roller.
The blade member is provided so that the displacement of the blade member can be adjusted in the separating direction.

[0008]

According to the present invention, the substrate and the supporting members are provided at both ends of the substrate in the longitudinal direction. Substantially L-shaped fitting grooves are formed on the inner surfaces of these supporting members that face each other, and these fitting grooves each have an axial direction of each shaft rod that rotatably supports a pair of rollers.
