  In the conventional general cutter knives described above, the adjustment of the way of cutting out the blade is set on the basis of the unit of the blade piece, and in the case of a cutter knife dedicated to cutting one sheet without an underlay, the cutting of the cutting edge can be adjusted. The one was matched to the paper thickness, and the mechanism of the functions of the former and the latter was completely different as a cutter knife.

  The present invention is based on the convenience of adding the function of a cutter knife dedicated to single-cutting that can finely adjust the way the blade tip comes out, based on how the blade tip of a conventional general cutter knife comes out based on the blade unit. It aims at solving and realizing each structural problem.

  In order to achieve the above-mentioned object, the present invention is formed so as to have a slide fine movement function in addition to a cutter knife function in which the blade slides and fixes in the order of each blade piece in the holder. In addition to the function to fix and release the slide movement, the fine-moving slide is slidably united, and a shaft insertion hole is provided to fit the adjuster shaft. The fine-moving slide has a cam operating hole and blade that accept the adjuster cam. A blade replacement convex part to be mounted is provided, and the adjuster is provided with a shaft part for rotational movement and a cam part for converting the rotational operation into a slide fine movement, and the shaft part of the adjuster is fitted into the shaft insertion hole of the slide body and the cam part. Is operated by the cam operating hole of the fine slide, and the blade of each slide movement fixed is set to 0 mm of the blade tip with 0 degree rotation adjustment by adjuster. By rotating the adjuster between 0 degrees and 180 degrees, the tip is finely moved so that it is included in the area on the line connecting the tip middle end and the tip bottom end of the holder blade exit direction end. The slide blade has a mechanism that allows fine movement of the blade between the minimum and maximum blades on the blade replacement convex part.

  Further, the means for solving the second problem is that the horizontal first cut edge and a part of the blade edge oblique side are exposed in parallel in the vicinity of the lower edge of the front middle end at the oblique side of the blade outlet direction end of the holder. A notch formed by the second cut side is provided.

  In addition to the normal function of the cutter knife, the action of the first problem solving means is that the adjuster is rotationally adjusted between 0 degrees and 180 degrees so that the cam portion of the adjuster operates in the cam operating hole of the fine movement slide. The blade mounted on the blade replacement convex portion provided on the fine movement slide is finely moved, so that the fine movement adjustment between the minimum and maximum extent of the blade tip corresponding to the cut from one sheet to the multiple cut is possible. it can.

  The second problem solving means is that the notch that is in contact with the hypotenuse at the end of the holder in the direction of the exit of the holder has a cutting edge set to a minimum of 0 mm by adjusting the adjuster in the line area of the hypotenuse and the hypotenuse of the cutting edge. Since it can be seen in a partially exposed state, fine adjustment corresponding to the paper thickness of a single sheet can be easily performed while checking the fine movement of the blade by adjusting the rotation of the adjuster, and the cutting edge can be seen. You can also cut by cutting one sheet while tracing the draft line.

  As described above, the cutter knife with a single-cutting function of the present invention is a cutter dedicated to single-cutting that can finely adjust the function of a general cutter knife and the way the blade tip does not need an underlay when cutting paper or the like. It is possible to provide a cutter knife with improved convenience and economy that combines the functions of a knife.

(A) An enlarged side view of the adjuster 7, (b) An enlarged bottom view of the upper figure (a).

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

  As shown in FIG. 7, a slider 5 and a fine movement slide 6 are slidably movable on the slide body 3, and as shown in FIG. 2, the shaft portion 7a of the adjuster 7 is rotatable so that the slide body 3 can rotate. The slide body 3, the slider 5, the fine movement slide 6 having the blade replacement convex part 6 a, and the adjuster 7 are inserted into the shaft insertion hole 3 a and the cam portion 7 b is operated by the cam operation hole 6 b of the fine movement slide 6. Are united together. In addition, as shown in FIG.10 (b), the cam part 7b is made into the column shape inscribed in the outer periphery of the axial part 7a. As shown in the partial sectional view of FIG. 6, the cam operating hole 6b allows the cam portion 7b to be inserted into the fine movement slide 6 with no gap between the lateral ends of the cam operating hole 6b, and between the longitudinal ends with the cam portion 7b. Is formed in a vertically long hole so that it can be inserted movably even during the maximum vertical movement due to the rotation of the adjuster 7.

  As shown in FIG. 3, the opening of the holder 1 is inserted into the upper and lower ends of the horizontal opening of the holder 1 by inserting a gap between the joint boundary grooves of the slide body 3 and the slider 5 and using the upper and lower ends as a guide. The release shaft is the one in which the protrusions 4a of the W-shaped spring 4 installed on the slide body 3 are engaged with the protrusions 2a of the blade 2 provided on the upper end of the blade 2 and the number of the blade pieces 2b of the blade 2 is fixed. When the slider 5 provided with 5a is slid back and forth, the release shaft 5a moves the convex part 4a downward, and the meshing with the concave part 1a is released to enable sliding movement.

  In addition, as shown in FIG. 1, the blade edge 2 a of the blade 2 for each slide movement and fixing set to a minimum of 0 mm by adjusting the adjuster 7 is located in a line area connecting the front middle end 1 c and the front lower end 1 d of the holder 1. A hypotenuse 1e is formed so as to be included, and a cut side that is horizontal around the lower side of the tip middle end 1c on the hypotenuse 1e and a cut side where a part of the hypotenuse side 2c is exposed in parallel are formed. A cutout portion 1b is provided.

  The operation of the above configuration will be described above. In addition to the general cutter knife function that fixes and releases the sliding movement of the blade 2 in and out by the concave portion 1a of the holder 1 and the convex portion 4a of the W-shaped spring 4 installed on the slide body 3, the adjuster 7 is set to 0 degrees. -By rotating 180 degrees, the fine movement slide 6 is finely moved by the cam portion 7b inserted into the cam operation hole 6b, and the blade 2 mounted on the blade replacement convex portion 6a is finely moved. Specifically, as shown in FIG. 1, when the adjuster 7 is set to 0 degree, the blade protrusion is 0 mm on the hypotenuse 1e line, and the position of the cam portion 7b is the axis of the shaft portion 7a as shown in FIG. It is facing backwards to the heart. Further, as shown in FIG. 4, when the adjuster 7 is set at 180 degrees, the cutting edge of the blade edge 2a in the direction perpendicular to the hypotenuse 1e is maximized, and the cam portion 7b is positioned at the shaft portion as shown in FIG. It faces forward with respect to the axis 7a. For example, if the maximum blade protrusion is 1 millimeter, the blade protrusion 2a can be finely adjusted between 0 millimeters and 1 millimeter in half rotation from 0 to 180 degrees, corresponding to the paper thickness. The cutting edge 2a suitable for cutting one sheet can be adjusted.

  In addition, as shown in FIGS. 1, 4 and 6, the notch 1b provided at the end of the holder 1 in the direction of the blade outlet can see the blade edge 2a by sliding fine movement. Is easy to set up.

  As described above, according to the present embodiment, while being visible at the notch 1b at the tip of the holder 1, by adjusting the exit of the blade edge 2a by the adjuster 7, the undercutting can be performed by cutting one piece, and It is also possible to obtain an effect that makes it easy to cut one sheet along a draft line such as a curve.
