To fully disclose the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout the specification.

Hereinafter, the present invention will be described with reference to the drawings for explaining a tape cutter according to embodiments of the present invention.

1 is a perspective view illustrating a tape cutter according to a preferred embodiment of the present invention. FIG. 2 is a cross-sectional view of a tape cutter according to a preferred embodiment of the present invention, in which a tape is cut. 3 is a cross-sectional view showing a state in which a tape of a tape cutter according to a preferred embodiment of the present invention is unwound.

1 to 3, a tape cutter according to the present invention includes a body 10, a roller 20, and a support 30.

The body portion 10 is formed with a coupling portion 11 on one side of which the tape 1 is rotatably engaged and a cutting portion 12 on the other side of which the tape 1 is cut.

At this time, the tape 1 is rolled up in the form of a roll in the engaging portion 11, and since it is a known technique, a detailed description on the method of using the tape 1 and the like will be omitted.

The body portion 10 is formed with a slotted hole 13 in the vertical direction so that the rotary shaft 21 of the roller 20 to be described later penetrates and can slide in the vertical direction.

The roller 20 is located below the cutting portion 12 and is rotatably coupled to the body portion 10. [

That is, the roller 20 is rotatably coupled to the body portion 10 so as to guide the tape 1 coupled to the coupling portion 11 when the tape 1 is rolled.

Further, the roller 20 is coupled to the body portion 10 so as to be slid in the vertical direction.

The rollers 20 are formed with rotation shafts 21 protruding on both sides.

That is, the roller 20 is vertically moved along the elongated hole 13 of the rotary shaft 21 and rotatably coupled to the body 10.

The user pulls the tape 1 in the upward direction when the tape 1 is unwound from the engaging portion 11 to cut the tape 1. Here, the roller 20 is moved upward along the longitudinal direction of the moving hole 13 by an external force that pulls the tape 1 by the user.

Then, when the user cuts the tape 1, the pulling external force is lost. At this time, the roller 20 is slid downward by a load or an elastic member 40 to be described later.

The support base 30 is located below the roller 20 and is coupled to the body 10 so that when the roller 20 is moved downward, it is engaged with the outer peripheral surface of the roller 20, 1).

That is, when the roller 20 is moved upward, the winding hole 22 is formed so that the tape 1 is wound, and when the roller 20 is moved to the lower side, it comes into contact with the support 30.

Accordingly, the roller 20 is slidably moved upward when the tape 1 to be wound is pulled upward by the external force, and when the external force is lost, the tape is pulled down by the load or the elastic member 40 To the support base 30.

The roller 20 is slidably moved upward so that the winding hole 22 is formed between the outer peripheral surface of the roller 20 and the support base 30 when an external force pulling the tape 1 to be pulled up is applied, And is slid downward by the load of the roller 20 when the external force disappears. At this time, the roller 20 fixes the tape 1 'which is wound by causing the outer surface of the support base 30 to come in contact with the tape 1' that has been wound.

Particularly, the adhesive surface of the tape 1 to be unwound is directed downward. As the roller 20 moves downward, the adhered surface of the tape 1 is adhered to the support table 30. Thus, the tape 1 'wound is not reeled or rewound by the engaging portion 11, so that the user can easily grasp the tape 1 when necessary and can easily use the tape 1 for reuse.

On the other hand, the support base 30 is formed to have a concave upper surface and a curvature corresponding to the curvature of the roller 20.

That is, when the outer circumferential surface of the roller 20 and the upper surface of the support base 30 come into contact with each other, they come into surface contact. Accordingly, the adhesive surface of the tape 1 'that has been wound is attached in surface contact when it is attached to the upper surface of the support table 30, and is not wound around the engaging portion 11.

Particularly, the tape 1 between the support 30 and the cutting portion 12 is maintained in the upper direction by the curvature of the support 30. Accordingly, it is possible to prevent the end of the unwound tape 1 ' from falling down and sticking to the outer circumferential surface of the body 10 or the wound tape 1. [ The user can easily hold the tape 1, which is convenient for use.

4 to 7 are sectional views showing an elastic member and its operation of a tape cutter according to a preferred embodiment of the present invention.

Referring to Figs. 4 to 7, the tape cutter according to the present invention further includes an elastic member 40. Fig.

The elastic member 40 pushes or pulls the roller 20 whose one end is fixed to the body and the other end is fixed to the roller 20 and is slid up and down so as to move in the direction of the support base 30.

That is, the elastic member 40 is fixed to a fixing pin 14 having one end protruding from the inner surface of the body 10 and the other end fixed to a rotation shaft 21 protruding from both sides of the roller 20, So that the outer peripheral surface of the roller 20 is supported on the outer surface of the support table 30. The roller 20 is supported on the outer surface of the support table 30 by pushing or pulling the roller 20 slidably moved upward.

The elastic member 40 may be composed of a torsion string or a coil spring, but is not limited thereto.

Therefore, when the user easily grips the end of the tape 1 erected by the support 30 and pulls the tape 1 upward, the user can drop and release the tape 1 attached to the support 30 by an external force . Then, the user cuts the tape 1 " through the cutter 12.

At this time, the roller (20) is moved in the direction of the support base (30) as soon as the external force applied to the tape (1) disappears by the elastic force of the elastic member (40). The adhesive surface of the tape 1 is attached to the support base 30 and is not wound or wound. In addition, the end of the tape 1 stands up toward the upper portion by the curvature of the support base 30.

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. The scope of the present invention is defined by the appended claims rather than the foregoing detailed description, and all changes or modifications derived from the meaning and range of the claims and the equivalents thereof are included in the scope of the present invention Should be interpreted.
