  A preferred embodiment of the present invention will be described with reference to the accompanying drawings. In addition, embodiment is not limited to the following forms, Other aspects can also be implemented if the subject of this invention can be solved.

FIG. 1 is a perspective view showing an information leakage prevention processing cutter 1 according to the first embodiment of the present invention.
This information leakage prevention processing cutter 1 is for cutting out only the protection information 3 to be prevented from leaking out of the information displayed on the sheet 2 such as paper and making it impossible to reproduce, and is shown in FIG. As described above, the rotary blade holder 20 that rotatably supports the rotary blade 10, the housing 30 that supports the rotary blade holder 20 so as to be movable up and down, and the operation unit 40 provided at the upper end thereof are configured.

The rotary blade 10 is intended to cause only the protection information 3 to be lost by running while pressing the peripheral surface of the sheet on the portion where the protection information 3 is displayed. A disk-shaped thin blade 12a, 12b is attached.
These thin blades 12 have a cutting edge that can be cut into a concavo-convex line, and by bringing the convex portions close to each other, as shown in FIG. Thus, the rotary blade 10 is designed.

That is, the projection 15 provided in the fixing member 14 is inserted into the attachment hole 13 provided in the first thin blade 12a, and the second thin blade 12b is similarly attached via the disc-shaped spacer 16. By being screwed in the screw hole 17 of the fixing member on the end side, the rotating blade 10 is integrated. At this time, the thickness of the spacer 16 between the thin blades 12 is adjusted so that the cut band 4 having a width corresponding to the size of the protection information 3 is formed.
By designing in this way, it is possible to manufacture the rotary blade 10 that can cut the sheet 2 with the two cutting edges provided on the peripheral surface to form the band-shaped cut band 4. By inserting the attachment shaft 21 of the rotary blade holder 20 through the pipe hole 18 of the rotary blade 10, the rotary blade 10 is rotatably attached to the rotary blade holder 20 (see FIG. 4).

An attachment shaft 21 for attaching the rotary blade 10 is fixed in a shaft hole 24 provided on the wall surface of the rotary blade holder 20 via fixing members 22 and 23.
The rotary blade holder 20 is supported to be movable up and down with respect to the housing 30 via a spring 26 while holding the rotary blade 10 (see FIG. 4).
That is, openings 31 and 31 are provided at corresponding positions on both wall surfaces of the housing 30, and a horizontal beam member 32 is installed in the openings 31 and 31. The crosspiece member 32 is fixed to the housing 30 at an attachment portion 33 provided on the wall surface.

Also on the wall surface of the rotary blade holder 20, openings 27 and 27 are provided at positions corresponding to the openings 31 and 31 of the housing 30, and the crosspiece member 32 is inserted through the openings 27 and 27. Thereby, it arrange | positions so that the inside of the rotary blade holder 20 may be penetrated (refer FIG. 4).
By disposing the spring 26 between the crosspiece member 32 and the ceiling portion 28 of the rotary blade holder 20, the rotary blade holder 20 is biased upward with respect to the housing 30. Assembled.

And the cap-shaped operation part 40 is provided on the rotary blade holder 20 so that the housing 30 may be covered.
The arrangement state of the spring 26 between the rotary blade holder 20 and the housing 30 is such that when the operation unit 40 is pushed down, the blade edge of the rotary blade 10 protrudes from the lower end portion of the housing 30 and the blade 2 has a predetermined edge of the sheet 2. It is designed so that the part can be cut.

A transparent paper pressing plate 34 is provided at the lower end of the housing 20.
As shown in FIG. 5, an opening 35 is provided at the center of the paper pressing plate 34, and the blade edge of the rotary blade 10 protrudes through the opening 35 when the operation unit 40 is pushed down. It is like that.
A line display 36 indicating a cutting line is provided on the extension lines of the blade edges of the thin blades 12a and 12b on both sides of the opening 35. By matching the line display 36, an accurate part can be cut out.

Both sides of the paper pressing plate 35 are raised in an inclined manner, and serve as guide portions 37 for smoothly moving on the sheet 2.
The operation unit 40 is provided above the housing 30 so as to be movable up and down with respect to the housing 30. The operation unit 40 is fixed to the ceiling 28 of the rotary blade holder 20 inside the cap shape.

A method of losing the protection information 3 from the sheet 2 using the information leakage prevention processing cutter 1 having the above configuration will be described with reference to FIG.
First, the information leakage prevention processing cutter 1 is placed on a portion of the sheet 2 where the protection information 3 is described. At this time, it is arranged through the transparent paper presser plate 34 while confirming the position where the protection information 3 is displayed.
Then, the operation unit 40 is pushed down. Thereby, the rotary blade holder 20 is pushed down with respect to the housing 30, and the two blade tips protrude from the opening 35.

By moving along the protection information 3 in this state, a corrugated cut band 4 as shown in FIG. 3B is formed. Then, the protection information 3 is separated from the sheet 2 by separating both ends of the cut band 4 from the sheet 2. Since the cutting band 4 at this time is connected to the sheet 2, it can be thrown into the waste box with its separated hands without being scattered as cutting waste.
In the case of an information resource such as an address and a name that produces value by combining a plurality of pieces of information, if one of them is separated (for example, only the name), the information value as the sheet 2 is lost. Therefore, the remaining cut sheet 2 can be effectively used as an information resource or a paper resource.

In particular, it is possible to safely dispose of items that cannot be shredded by a shredder from the viewpoint of environmental protection, such as mails whose addresses are attached to envelopes made of transparent cellophane.
In addition, since the rotary blade is configured by attaching a plurality of thin blades having cutting edges that can be cut to the uneven line to the rotating shaft, an uneven cut band can be formed. It is possible to make it difficult to read by running the blade edge along the character string on the information to be lost from the page.

In addition, since the rotary blade 10 is formed by combining the two thin blades 12a and 12b, the width between the thin blades can be made variable by adjusting the width of the spacer 16 inserted therebetween. This makes it possible to cut the sheet to a width that matches the character size. In addition, you may enable it to adjust the width | variety of a cutting band by replacing | exchanging the whole rotary blade or the whole rotary blade boulder.
Furthermore, since the cutting edge of the rotary blade 10 is exposed from the housing 30 by depressing the operation unit 40, safety when not in use is ensured. In addition, the information that should be prevented from leaking can be cut out by placing it on a desired part on the sheet and moving the operation unit 40 while pushing it down with the palm of the hand. The risk of touching is low.

In particular, since a transparent plate displaying the position of the blade edge of the rotary blade is attached to the lower end of the housing, the information to be leaked can be ensured by aligning the display with the position of the information to be prevented from leaking. It can be separated from the sheet.
In the present invention, any structure may be used as long as it is a cutter that cuts off the protection information 3 by pressing the peripheral surface of the rotary blade 10 against the portion of the sheet 2 where the protection information 3 is displayed. For example, as shown in FIG. 6, the thin blade 12 ′ constituting the rotary blade 10 ′ can be a round blade for linear cutting.
In this way, as shown in FIG. 6 (b), since it can be a straight cut band 4 ', not only the information remaining on the paper surface, but also the information separated from the paper surface, It can be effectively used as new information.

Further, as shown in FIG. 7, the rotating blade 10 ″ may be configured such that the convex portions of the thin blade 12 ″ are brought into close contact with each other to form a mesh-like cutting line.
In this way, both ends of the incision band 4 ″ can be separated from the sheet 2 without tearing by hand. Even when the cutting edge is not perfectly mesh-like due to the inclination of the blade edge, Since the width of the narrow portion of the band 4 ″ can be made as small as possible, it can be easily torn off by hand when separated from the sheet 2.
When it is desired to crush to an unrecoverable state as an indefinite fine fragment, the cut band 4 ″ can be cut off by reciprocating over the protection information 3.

According to the present embodiment, the plurality of blade edges provided on the peripheral surface of the rotary blade is configured by attaching a plurality of disk-shaped thin blades along the axial direction of the rotary shaft, and thus has a straight blade edge line. A cutting edge having a desired shape can be obtained by appropriately designing or changing the cutting edge shape of the thin blade, such as a thin blade or a thin blade having a wavy cutting edge line.
For example, when this information leakage prevention processing cutter is run only on the name part of a mail piece, the postal address and name are separated, and personal information can be effectively protected. By storing or filing a cut piece (name part), it can be reused as information for classification and number management of received mail items.

The rotary blade of the present invention can be, for example, a cylindrical rotary blade, as long as the part can be separated from the sheet by traveling while pressing the peripheral surface against the part on which the protection information of the sheet is displayed. The peripheral surface may be provided with a cutting edge capable of being cut in a mesh-like (that is, mesh-like, honeycomb-like) line.
In this way, the protection information that should be prevented from leaking can be cut into a mesh shape, so that it cannot be restored as fine shredded waste.

The assembled state of the rotary blade holder, the housing, and the operation unit can also be changed as appropriate. For example, the blade edge may be prevented from protruding from the housing when not in use by biasing the rotary blade holder upward by a spring interposed between the rotary blade holder and the bottom of the housing. And an opening part may be provided in the top | upper surface of a housing, and a pushbutton-shaped operation part may be arrange | positioned.
