Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a tape cutter that accommodates a winding tape and can cut the tape to an arbitrary length at a required place.

[0002]

[Prior art]

 There is a cutter that is attached to a winding tape and carried to a necessary place and cut it to a desired length. This cutter includes, for example, a metal fitting with a blade that is fitted around the peripheral portion of the winding tape so as to be movable in the circumferential direction.

This metal fitting with a blade is externally fitted so that the blade is positioned at the outer peripheral portion of the winding tape and faces outward. When using, the tape is peeled off for a required length and a tensile force is applied to this. It is pressed against the blade and cut.

[0004]

[Problems to be solved by the device]

 With a conventional cutter such as the above-mentioned blade metal fitting, it is difficult to cut the exact position of the winding tape, and after cutting, the unused end of the winding tape adheres to the remaining tape peripheral surface. It takes a great deal of time to pick up the cut end for the next use, and it is often the case that this tape is damaged.

An object of the present invention is to provide a tape cutter that can deal with such a situation.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, in the present invention, a tape holder is formed which holds a winding tape so that it can be freely taken out and put in and can be rotationally displaced, and a tape having a constant length in the circumferential direction is formed on the peripheral surface of the holder. An extraction hole is provided, a receiving piece for supporting the lower surface of the tape is fixed to the front end of this extraction hole, and an elastic plate is extended from the rear end of the extraction hole toward the front end to cover the extraction hole. Then, a pressing piece for pressing the upper surface of the tape is fixed to the tip of the elastic plate in correspondence with the receiving piece, and further, a sliding operation plate is attached to the upper surface of the elastic plate so that the sliding operation plate can be slidably displaced forward and backward. At the same time, fix the tape cutting blade to the lower surface of the tip of the sliding operation plate.

At this time, in order to make the device of the present invention easy to grip, the tape holder is a cylinder in which side plates having circular holes formed in the central portion are opposed to each other, and the circular holes are wound to fit the tape. The structure is made by connecting with a core.

[0008]

[Embodiment of the invention]

 FIG. 1 is a view showing a tape cutter according to an example of the present invention, FIG. 2 is a side view showing a cross section of a main part thereof, and FIG. 3 is a view for explaining the cutting operation.

In these drawings, reference numeral 1 denotes a tape holder, and specifically, a pair of side plates 2 having a circular hole a formed at a central portion are opposed to each other, and a space between the circular holes a facing each other is provided. The tape core t is connected by the cylindrical core 3 fitted onto the outer circumference.

Reference numeral 4 denotes a lead-out hole of the tape t1 provided on the upper peripheral surface of the tape holder 1, a receiving piece 5 for supporting the lower surface of the tape t1 at the front end thereof, and a side plate 2 on the rear end side. The connecting plate 6 is fixed between the two.

Reference numeral 7 denotes an elastic plate, which extends from the rear end portion of the extraction hole 4 toward the front end portion so as to cover the extraction hole 4. At this time, a push piece 8 for pushing the upper surface of the tape t1 is provided at the tip of the elastic plate 7 so as to correspond to the receiving piece 5.

Reference numeral 9 denotes a sliding operation plate attached to the upper surface of the elastic plate 7 so as to be slidable in the front-rear direction. Specifically, as shown in FIG. 10 is fixed, and one side is provided with a guide hole 11 in the front-back direction in the center of the width of the elastic plate 7, and the guide holes 11 are used to guide the pins 10, 10 in the front-back direction.

Reference numeral 12 denotes a tape cutting blade fixed to the lower surface of the tip of the sliding operation plate 9.

An example of use of the product of the present invention and its operation will be described. By removing the cylindrical core 3 or the like, a winding tape t wound with an adhesive tape is fitted onto the cylindrical core 3 between the side plates 2 and 2, and the tip end side of the tape t1 is indicated by an imaginary line in FIG. Pull out from the pull-out hole 4. At this time, if the presence of the elastic plate 7 and the sliding operation plate 9 is an obstacle, they are bent upward to open the extraction hole 4 largely.

When using the winding tape t accommodated in the tape holder 1 in this manner, the product of the present invention is carried to the place of use, and the pull-out hole 4 The portion of the tape t1 pulled out from is picked up and pulled. As a result, the tape t1 adhered to the winding tape t is peeled off and pulled out, and during this pulling out, the winding tape t is rotated around the cylindrical core 3.

After pulling out the required length of the tape t1 in this way, the sliding operation plate 9 is pushed forward by a finger to be displaced as shown in FIG. This displacement is restricted in its moving direction and maximum moving distance by the pin 10 and the guide hole 11.

The displacement amount of the sliding operation plate 9 is adjusted to be optimum in relation to the required length of the tape t1 to be adhered.

After that, the sliding operation plate 9 is pressed by a finger to bend the elastic plate 7 so that the front portion 7a thereof is lowered as shown in FIG. 3A. The tape t1 pulled out from the tape is pressed on the receiving piece 5 on the way to reliably regulate the movement of the tape t1 in the front-rear direction.

Under this regulated state, the tape holder 1 is pulled up obliquely upward as shown by an imaginary line k in FIG. 3A. As a result, the tape t1 is pressed against the tape cutting blade 12 and the intended position is accurately cut.

Finally, the sliding operation plate 9 is moved backward as shown in FIG. 3B to prepare for the next use. At this time, the outer end of the tape t1 that has passed through the drawing hole 4 is in a state of slightly protruding from the receiving piece 5, and this outer end serves as a margin for picking up the next drawing.

[0021]

[Effect of the invention]

 According to the present invention constructed as described above, when cutting the winding tape, the cutting end e of the tape t1 can be adjusted to a desired length by arbitrarily adjusting the moving amount of the sliding operation plate. Since it can be cut accurately under the protruding state of s, so that the necessary picked portion can be surely left, it is convenient to use the next tape and the workability is improved.

According to the second aspect of the present invention, the winding tape can be protected by the side plate, and the finger can be conveniently grasped by inserting the finger into the circular hole of the side plate.
