Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutter as a stationery for cutting paper and the like, and more particularly to an electric rotary cutter which is used by holding it with one hand.

[0002]

2. Description of the Related Art As a stationery for cutting papers, a cutter having a rotatable blade rotatably attached to the tip of a handle is known. In this cutter, the user pushes the rotary blade in a state where the rotary blade is put on the paper to be cut, thereby rotating the rotary blade to cut the paper.

[0003]

[Problems to be Solved by the Invention] However, in the above-mentioned conventional cutter, the user has to push the cutter by his / her own force, and it takes time and effort to cut the paper. In addition, there is a problem that the rotation of the round blade varies, and the round blade is easily damaged. The present invention
This is to solve such a problem in the conventional cutter.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, according to the present invention, a round blade is fixed to an output shaft of a motor, and the round blade is stored in an upper side with a lower portion of the round blade protruding downward. It is stored in a case, and a lower storage case is disposed below the upper storage case with a slight gap between the lower storage case and the upper storage case via a separator plate behind the round blade. The present invention provides an electric rotary cutter in which a lower end portion of a round blade is stored and a guide surface of an object to be cut is formed on an upper surface of a lower storage case.

[0005]

When using the electric rotary cutter of the present invention, the user holds the electric rotary cutter with one hand (for example, the right hand), and inserts a paper as an object to be cut into a gap between the upper storage case and the lower storage case. In this state, the circular blade may be rotated by the motor to advance the cutter. At this time, the object to be cut is cut by the round blade rotated by the motor while moving relatively on the guide surface on the upper surface of the lower storage case with respect to the cutter.
The object cut by the round blade is divided into right and left by a separator plate behind the round blade. The object to be cut may be held by the other hand (for example, the left hand), or may be cut while being fixed by a clip or other fixing means.

[0006]

Next, an embodiment of the present invention will be described with reference to the accompanying drawings. The round blade 3 is fixed to the output shaft 2 of the motor 1. The round blade 3 is stored in the upper storage case 5 with the lower portion 4 of the round blade 3 protruding downward. That is, the through hole 7 corresponding to the round blade 3 is formed in the bottom 6 of the upper storage case 5. A lower storage case 9 is disposed below the upper storage case 5 via a separator plate 8 behind the round blade 3 with a slight gap 10 between the lower storage case 9 and the upper storage case 5. Reference numeral 11 denotes a guide portion 11 for facilitating the cut object 12 to enter the gap 10. The guide portion 11 is formed by projecting the bottom 6 of the upper storage case 5 forward and bending it upward. . The lower storage case 9 stores the lower end 4 ′ of the round blade 3. A guide surface 13 for an object to be cut 12 is formed on the upper surface of the lower storage case 9. Reference numeral 14 denotes a through hole formed in the guide surface 13 corresponding to the lower end 4 ′ of the round blade 3. The through hole 14 is located immediately before the separator plate 8. Further, it is desirable to provide a battery 15 as a power source for the motor 1. Battery 1
Numeral 5 is disposed in a handle 16 having one end fixed to the motor 1 or the upper storage case 5 as an example. 17 is motor 1
A switch 18 for N-OFF is a projection for facilitating gripping of the grip 16. A cap 19 is detachably attached to the upper end of the handle 16 so that the battery 15 can be taken in and out.

[0007]

[Effects of the Invention] As described above, the electric rotary cutter of the present invention rotates the round blade by the motor, so that the rotation of the round blade becomes constant unlike the conventional one in which the cutter is manually pressed. And a stable cutting operation can be performed. Needless to say, the efficiency of the cutting operation is significantly improved.
