[Problems to be Solved by the Invention] However, in the prior art, a firm fixing method using screws or screws is used for fixing the blade, and the blade cannot be easily replaced. Since the lower end of the blade is not inserted to the inside of the cutter table, the blade is cut at the tip of the blade, and the curing sheet escapes from the tip of the blade. Further, when the blade is housed inside the cutter handle, it is necessary to match the direction of the blade with the direction of the cutter handle, and there is a problem that the blade can be arranged only downward.

[0004]

The present invention uses the following means to solve the above-mentioned problems. In the cutter for cutting the curing sheet S, the taper
In the center of the upper part of the cutter base 1
-Attach the blade case 2, and furthermore,
The cutter handle 3 protrudes obliquely upward and the cutter blade C is inserted into a cutter blade groove 4 provided at the base of the cutter handle 3, and the cutter blade groove 4 extends from the upper end of the cutter handle 3. The cutter blade 1 is drilled through the case 2 to reach the cutter base 1, and the lower end of the cutter blade groove 4 is formed inside the cutter base 1 so that the cutter blade C does not fall from the cutter blade groove 4. Further, a sheet suppressing projection 3b is provided immediately before the cutter blade C at the base of the cutter handle 3.

As an embodiment of the curing sheet cutter of the present invention, a curing sheet cutter A shown in FIGS.
And the curing sheet cutter B shown in FIGS. 10 to 12.
Will be described.

First, the curing sheet cutter A will be described. The material of the curing sheet cutter A uses resin. The cutter table 1 is inclined in a tapered shape, and has a shape that makes it easy to catch the end of the curing sheet S as shown in FIG. A cutter blade case 2 is attached at the center of the upper part of the cutter base 1 on the side opposite to the X side, and a cutter handle 3 is further projected obliquely above the upper part. Then, a cutter blade groove 4 is provided from the upper end of the cutter handle 3 to the cutter blade case 2 and the cutter table 1.

In the cutter blade groove 4, a blade suppressing protrusion 3 a is provided in the portion of the cutter handle 3 as shown in FIG. 2 so that the cutter blade C fitted in the cutter blade groove 4 does not swing. The cutter blade groove 4 exposes the cutter blade in the cutter blade case 2. The vertical width of the exposed portion is slightly larger than the thickness of the curing sheet, so that the curing sheet can be reliably cut. Further, the cutter blade case 2 has the same thickness on the side opposite to the X as the cutter handle 3, but has a smaller thickness on the side of the cutter blade C, so that the sheet cut by the cutter blade C does not interfere with the next cutting. It has a function to open.

Since the bottom of the cutter blade groove 4 is located in the cutter table 1, the floor is not damaged by the cutter blade.
The floor can be further prevented from being scratched by applying a felt or the like to the bottom surface of the cutter table 1. The blade replacement hole 1 extends from the bottom surface of the cutter base 1 to the bottom of the cutter blade groove 4.
a. The blade replacement hole 1a is configured to insert a screwdriver or the like to push up and remove the cutter blade C in the cutter blade groove 4.

The cutting is performed by grasping the cutter handle 3 and pulling it in the X direction. A problem in cutting is that the cut sheet floats up, and the sheet to be cut next is lifted up. For this reason, by providing the sheet holding projection 3b at the base of the cutter handle 3 at a position before the exposed portion of the blade in the cutter blade case 2, the sheet is prevented from floating and the cutter is correctly guided. The sheet holding projection 3b
Also has a function of protecting a finger or the like of a hand gripping the cutter handle 3 from being accidentally touched by the cutter blade and not being damaged. Reference numeral 3c denotes a string hole for storing the cutter.

The curing sheet cutter A is configured as described above. For example, even when the curing sheet S is in close contact with the floor as shown in FIG. 7 or when the curing sheet S is floating as shown in FIG. In addition, the function of the cutter table 1 and the sheet holding projections 3b makes it possible to cut the sheet reliably and quickly without floating the sheet and without damaging the underlying floor or sheet. Also, as shown in FIG.
Is wound in a roll at the time of packing, but if the curing sheet cutter A is used, the packed sheet can be cut without damaging other portions of the sheet wound by the cutter table 1.

Next, an embodiment of the curing sheet cutter B will be described. The curing sheet cutter B can be configured to be handmade, and the material of the cutter table 5 or the cutter handle 6 may be wood, ABS resin, or the like. Cutter stand 5
Are inclined in a tapered shape like the curing sheet cutter A. Grooves 5a and 6a for mounting the cutter blade case 7 are dug in the side surfaces of the cutter base 5 and the cutter handle 6, and the cutter blade case 7 is embedded in the groove and fixed with screws or the like, and the cutter base 5 and The cutter handle 6 is connected. As shown in FIG. 12, the cutter blade case 7 is formed by bending a steel plate into a U-shape so that the tip of the cutter blade can be inserted. A groove 5b for mounting a cutter blade is provided on a side surface of the cutter table 5, and a screw hole 5c for screwing a thumb screw 8 for fixing the cutter blade is formed. The cutter blade C is buried in the groove 5b with the blade facing upward, the tip is inserted into the cutter blade case 7, and the hole already provided in the cutter blade C is aligned with the screw hole 5c and fixed with the thumb screw 8. In addition,
If the U-groove of the cutter blade case 7 is crushed at the portion 7a immediately below the inserted cutter blade C, the cutter blade C does not rub down. The portion immediately before the cutter blade C at the base of the cutter handle 6 constitutes a protruding portion 6b for both safety and sheet suppression, similarly to the curing sheet cutter A.

Since the curing sheet cutter B is constructed as described above, the sheet cutting surface is not bent by pulling in the direction of the arrow X 'in FIG. 10, and the curing sheet can be cut quickly. Also in each case of the curing sheet S as shown in FIGS. 7 to 9, the same function as the curing sheet cutter A is exerted, and quick and reliable cutting can be performed without damaging other parts.

[0014]

Since the present invention has the above-described structure and embodiment, it has the following effects. First, a cutter blade groove 4 into which the cutter blade C is inserted.
Is provided from the cutter handle 3 to the cutter base 1 downward, so that the cutter blade C is simply inserted into the cutter blade groove 4 without easily fixing the cutter blade C firmly with screws or screws. In the inserted state, the cutter blade C can be held. Second, the cutter blade groove 4
Is provided from the cutter handle 3 to the cutter table 1 via the cutter blade case 2 without being configured inside the cutter handle 3, so that the cutter blade C is not limited to the direction of the cutter handle 3. The corresponding angle between the sheet and the curing sheet S can be arranged at a right angle or an upward angle. Third, since the cutter blade groove 4 is extended into the cutter table 1 and the lower end is locked inside the cutter table 1, the tip of the cutter blade C constitutes a cutting portion. However, since it is used only as a fixing portion of the cutter blade C, the cutter blade C can be securely fixed, and the holding force of the cutter blade C that can sufficiently withstand the pressing force of the curing sheet S can be obtained. You can. In addition, by using not the tip of the cutter blade C but the middle part as the cutting part, the cutter blade C does not escape due to the pressing force of the curing sheet S, and the sharpness can be improved. Fourth, since the projection is formed immediately before the cutter blade C at the base of the cutter handle 3, the finger or the like of the hand holding the handle is safe without touching the blade, and the rising of the curing sheet S is suppressed. The cut surface can be reliably cut without bending.
