SOLUTION: Cutter levers are assembled with this paper cutter device with a predetermined space from a paper take-out part, and one end of one cutter lever is formed as a working lever, and the other end thereof is formed as a working rod, and the other cutter lever is formed as a cutter. The force is increased by the leverage by utilizing the force cut by the paper cutter. A slider is folded or pulled by the working rod of the cutter lever to hold the paper, and the paper is cut while stopping any advance of the paper.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a long-wound paper or paper-like material such as paper towel, toilet paper, Saran wrap, aluminum foil, gum tape,
The present invention relates to a paper cutter device capable of safely cutting an adhesive tape or the like (hereinafter referred to as paper) to a required length with one touch and with one hand. 2. Description of the Related Art A conventional long-winding paper cutting apparatus draws out one end of a roll-shaped paper with one hand, determines the required length, and presses a part of the roll or paper with the other hand to remove the paper. The paper is pressed against the cutter while cutting to prevent the tape from being cut out, and there is an inconvenience that the cutting cannot be performed unless both hands are used. In addition, a cutter is indispensable for cutting the paper, but a sharp blade is required for accurate cutting, but there is a danger of injuring the hand, so the blade is rounded, They were perforated or used paper that was easy to tear. [0003] The long-winding paper cutting device according to the present invention utilizes the force of cutting the paper drawn to a required length, rotates the cutter lever,
By using a lever, the slider can be pushed or pulled to hold the paper, preventing the paper from coming out and cutting the paper reliably with only one hand operation. [0004] A cutter lever is assembled at a predetermined distance from a paper take-out portion, and one end is formed as a working lever, the other end is formed as a working rod, and the other is formed as a cutter. Use the force to cut the paper with a cutter, increase the leverage action, push or pull the slider with the action lever of the cutter lever, press the paper, stop the paper picking out, and remove the paper. Disconnect. An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows an example of a roll paper cutting device. 1 is case, 2 is roll paper,
3 is a roll paper shaft, 4 is a cutter lever, 5 is a slider, 6 is a slider case, 7 is a slider opening, 8 is a paper end, 21 is a cutter lever lever, 22 is a cutter lever fulcrum, and 23 is a cutter lever fulcrum. Bearing portion of the cutter lever, 24 is a cutter portion, 25 is a working rod, 26 is a cutter protection portion, 27 is a paper press portion of the slider, 2
8 is a paper receiving portion. 2 shows a lever differential state when paper is cut, FIG. 3 is a top view of FIG. 1, and FIG. 4 is an explanatory view of another embodiment in which paper is taken out upward.
4 is an explanatory view of the operation of the other embodiment of FIG. 4, FIG. 6 is a detailed view of the cutter lever, and FIG. 7 shows an example of a case where the slider is pulled to stop the paper. The operation of the paper cutting device constituted by the above members will be described below with reference to FIGS. 1 and 2. FIG. 1 shows a case where the paper cutting device is set to a normal position. The cutter lever 4 is supported by its fulcrum 22 and a bearing 23 and is set so as to be able to rotate at a fixed angle. A slider 5 having one end as an operation lever 21, the other end as an operation rod 25, and the other one as a cutter 24, is incorporated so as to be able to slide back and forth in the slide case 6. The paper pressing portion 27 of the slider 5 is in contact with the paper receiving portion 28 fixed to the case, and is formed so as to have a predetermined distance from the cutter lever 4. The cutter portion 24 of the cutter lever 4 is normally covered with the cutter protection portion 26, and there is no danger of injury to the hand. The paper end 8 is a paper holding part 27 of the slider.
And the paper receiving portion 28, and is hung down through the frontage portion 7. FIG. 2 shows the operation when the paper is cut by the paper cutting device, and its embodiment will be described as follows. As is apparent from the drawing, the end 8 of the paper is brought into contact with the lever portion 21 of the cutter lever 4 after being pulled out by a predetermined length, and is pulled to the left in the drawing.
The cutter lever 4 rotates about the fulcrum 22, and the operating rod 25 pushes the slider 5 to release the paper presser 27.
The paper is sandwiched and fixed between the paper receiving portion 28 and the paper receiving portion 28.
The cutter portion 24 of the cutter lever 4 is easily cut with one hand by jumping out of the cutter protection portion 26, biting into the paper, and further pulling. [Other Embodiment] The other embodiment shown in FIG. 4 shows a case where the paper end 8 is taken out upward.
The constituent members of the paper cutter device are all formed from the same or the same effect members as in the previous embodiment, and the operation shown in FIG. 5 is also the same as in the previous embodiment. FIG. 6 is a perspective view of the cutter lever, and the relationship among the cutter lever 21, the cutter portion 24, and the operating rod 25 is clearly shown. [Other Embodiments] FIGS. 7 and 8 show another embodiment. In this embodiment, a slider 5 which slides in a slider case 6 is provided as shown in FIG. When the paper end 10 is pulled to the left side in the figure by the lever 4, the paper end 10 is fixed by the opening 7 of the slider, and the paper end 10 is cut and separated by the cutter 9. In the paper cutter device according to the present invention, the cutter formed on one of the cutter levers is normally protected by the cover and is safe, and the cutter lever rotates during cutting. Thereby, the cutter jumps out and bites into the paper, so that cutting can be facilitated. In the paper cutter device according to the present invention, a predetermined interval is maintained from the place where the paper is pressed to the cutter, so that the next paper can be easily taken out. In addition, the paper cutter device according to the present invention not only enables a safe cutting without touching the blade, but also keeps the length of the paper end after the cutting that allows the next removal. Facilitates removal.
