Description

  The present invention relates to an information outflow prevention punch that makes a plurality of holes in paper or the like to be punched and makes characters and numbers unreadable in order to prevent outflow of information such as characters on paper. It is.

  Since the enactment of the Personal Information Protection Law, the leakage of personal information in companies has also resulted in the loss of the company's credibility, so that personal information is processed so that it is unreadable. Conventionally, processing using a large shredder that cannot be easily carried as a means has been performed.

  Also, at home, papers with the most basic personal information address and name are sent, such as direct mail, direct debit details, New Year's cards, etc. The demand for spill prevention is increasing rapidly. On the other hand, as a measure for preventing information leakage at home, a shredder has been relied on in the past, but an accident in which a child pinches the finger has occurred, and the conventional shredder type information leakage prevention has been reviewed.

  As a result, personal-type shredders have been put into practical use. In addition, a portable device that cuts out a personal information portion by a punch by punching has been put into practical use.

For example, in Patent Document 1 below, it is difficult to grasp information represented by punch objects by moving a punch blade composed of two or more punch blades to open a plurality of holes in the punch object. Punches for preventing information leakage that are close to each other have been proposed.
JP 2004-25361 A

  Shredders are large and require a large space for installation, as well as electricity. Also, if you put a lot of vinyl or a large amount of printed material on the shredder at once, the paper shreds and the shredder often does not work, and it is troublesome to remove the jammed paper. It is pointed out that it occurs frequently.

  In addition, since each personal type shredder is processed by turning the handle by hand and moving the teeth, it takes time.

  The conventional personal type that is portable and cuts out personal information by pinpointing has the function of processing type characters within 7 centimeters per line in one line, and is described in multiple lines It takes a considerable amount of time and labor to process everything that is handwritten or handwritten. In addition, it is difficult to accurately match the part to be cut out, and the work must be repeated many times.

  As described above, since there is no tool that can be easily processed in the past, the printed matter containing personal information was often broken by hand, but breaking by hand requires more power depending on the type of paper. Depending on the method, personal information may remain, resulting in information loss.

  In addition, since the information leakage prevention punch described in the above-mentioned Patent Document 1 has only one row of punch holes, in order to make the described information indecipherable, it is necessary to open a hole many times. There is a problem that a large number of punch objects cannot be processed at once.

  Therefore, the present invention solves the above-mentioned problems of the prior art, and opens a two-dimensional hole with a small pressing force in a punch object having a size of a postcard or A4 paper containing personal information in one operation. It is an object of the present invention to provide a punch for preventing information leakage.

As a result of intensive investigations to solve the above-described problems, the present invention arranges a plurality of punching blades two-dimensionally in the row direction and the column direction, thereby providing postcards and A4 containing personal information in a single operation. An information leak prevention punch capable of easily punching a confidential document having a paper size is provided, and the gist of the punch is as follows.
(1) A lower base having a plurality of lower blades and an upper base having a plurality of upper blades provided at positions facing the lower blades, wherein the plurality of opposed lower blades and upper blades are in a row direction. And two-dimensionally arranged in the row direction, each end of the lower base and the upper base is pivotally fixed, and by pressing the upper base, the upper blade of the upper base is lowered to be punched An information outflow prevention punch characterized in that information described in a punch object is made unreadable by opening a plurality of holes arranged in a row direction and a column direction in the object.
(2) A rotary spring that holds the lower base and the upper base in a state where the lower base and the upper base are opened is provided on a rotary shaft that rotatably supports each end of the lower base and the upper base, and the upper blade is raised on the upper base. The information outflow prevention punch according to (1), further comprising: a lifting spring that holds the bent spring in a state where the repulsive force of the rising spring is larger than the repulsive force of the rotating spring.
(3) Crossbars fixed by floating pins at both ends of the upper base, and when the upper portion of the upper base is pressed, the floating pins slide in a slit provided in the crossbar and the cross The information leakage preventing punch according to (1) or (2), wherein the pressing force pressing the upper base is reduced by tilting the bar.
(4) The information leakage preventing punch according to any one of (1) to (3), wherein the diameters of the lower blade and the upper blade are 3 mm to 20 mm.
(5) The waste container according to any one of (1) to (4), further including a waste bin that accumulates waste generated by opening a hole in the punch target, below the lower base. Punch for preventing information leakage.
<Action>
According to the invention of (1), since the plurality of lower blades and upper blades provided so as to be opposed to each other in the vertical direction are arranged two-dimensionally in the row direction and the column direction, the size of the postcard and the A4 size punch target Since a large number of punch holes can be opened in an object at a time, personal information included in the object to be punched can be easily made unreadable.

In the present invention, the size of the arrangement surface of the punch holes is not limited, but it is preferable to arrange them in the size of a palm or the size of a postcard.
According to the invention of (2), the repulsive force of the rising spring that holds the upper blade in the raised state on the upper base is made larger than the repulsive force of the rotating spring that holds the lower base and the upper base in an open state. Until the upper base and the lower base are closed by pressing the upper base, the rotary spring operates preferentially and the ascending spring does not operate. Therefore, the upper blade does not descend, and there is no fear of damaging the finger accidentally.

That is, the upper blade of the upper base facing the lower base of the lower blade portion is fixed at one end with a rotating shaft, and the upper surface of the upper base is pressed after the surface of the lower base and the upper base are in contact with each other. The upper blade descends vertically to make a hole in the punched object, so that a safe structure is obtained. At this time, it is important that the rotating shaft that fixes the lower base and the upper base is a hinge or a rotating spring that is weaker than the rising spring provided in the upper base.
According to the invention of (3), the upper base has crossbars fixed by floating pins at both ends, and when the upper part of the upper base is pressed, the floating pins are inserted into the slits provided in the crossbar. As the cross bar slides and tilts, the pressing force that presses the upper base is reduced, so that a plurality of punch objects having a large size are arranged two-dimensionally in the row direction and the column direction at a time. Since the hole can be opened with a small force, it is possible to easily prevent leakage of confidential information.
According to the invention of (4), since the diameters of the lower blade and the upper blade are 3 mm to 20 mm, it is possible to easily make a hole to the extent that the information contained in the punch object is unreadable, and to make it unreadable. For this purpose, the diameter of the gap between adjacent blades is preferably 3 mm to 20 mm.
According to the invention of (5), since it has a waste bin that accumulates the waste generated by punching a hole in the punch object below the lower base, it can be used as a waste receptacle after punching. , Garbage is not scattered.

According to the present invention, it is possible to provide an information outflow prevention punch that can open a two-dimensional hole with a small pressing force on a punch object having a size of a postcard or A4 paper containing personal information in one operation. Specifically, the following industrially significant effects can be obtained.
Although the conventional personal type has a small number of perforations and its range is narrow, as described above, the punch of the present invention has a palm size or postcard size and a wide perforation range. Punching personal information and confidential documents with a single punch makes it illegible and processable. In addition, at home, direct mail such as postcards and envelopes, bank usage details, expired credit cards, membership cards, etc. At companies, information output from personal computers, A4 paper on which customer personal information is written or There is a wide range of use for punching personal information such as postcard-sized documents, and it is efficient because personal information can be made substantially unreadable easily at one time. Here, “illegible” means either or both of a case where the character cannot be read and a case where the meaning is unknown.

  Moreover, the punching object can be punched without problems even if it is made of vinyl as well as paper, and can be placed on a desk for processing. In addition, the base on which the punch object is placed is fixed by a hinge only on one side, so that even if a paper jam occurs, it can be easily removed.

  Even if the punch object protrudes from the size of the lower base, the punch object can be folded and punched once, or the punch object can be moved on the lower base and punched twice. It is. Since the base for punching is the size of a palm or the size of a postcard, information described therein can be easily made unreadable.

  Furthermore, unlike a shredder placed on the floor, it is not necessary to secure a power source, there is no space problem, and there is no failure due to a paper jam.

  In addition, because of the structure, the upper base cannot be pressed unless the upper base and the lower base are in contact with each other, and it is safe without the upper blade coming out of the upper base and cutting the finger.

  The information outflow prevention punch according to the present invention prevents the outflow of information by making a plurality of holes in a punch target. Here, punched objects are, for example, direct mail such as postcards and envelopes at home, bank usage details, expired credit cards, membership cards, etc. This refers to all objects consisting of documents up to about A4 size on which information is written.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

  1 to 9, 1 is a lower base, 2 is an upper base, 3A, 3B, and 3C are lower blades, 4A, 4B, and 4C are upper blades, 5 is a waste container, 6 is a top plate, and 7 is a lift spring , 8 is a rotating shaft, 9 is a top plate receiving portion, 10 is a cross bar (upper plate), 11 is a cross bar (lower plate), 12 is a fixing screw (fulcrum), 13 is a floating pin, 14 is a slit, 15 is The upper surface plate slide space, 16 is a punch object, 17 is a rotary spring, and 18 is a scrap holder.

  FIG. 1 is a perspective view illustrating an embodiment of an information leakage preventing punch according to the present invention.

  In FIG. 1, the lower base 1 has a plurality of lower blades 3A, 3B, 3C,..., The upper base 2 is placed on the lower base 1 so as to face it, and the upper surface plate of the upper base 2 is pressed. The upper blades 4A, 4B, 4C,... Of the upper base 2 are lowered to fit the lower blades 3A, 3B, 3C,. .

  The present invention includes a lower base 1 having a plurality of lower blades 3A, 3B, 3C,... And an upper base 2 having a plurality of upper blades 4A, 4B, 4C,. A plurality of opposed lower and upper blades are arranged two-dimensionally in a row direction and a column direction, and each end of the lower base and the upper base is pivotally fixed, By pressing the base, the upper blade of the upper base descends to open a plurality of holes arranged in the row direction and the column direction in the punch target, thereby making the information described in the punch target unreadable. It is characterized by. The two-dimensional arrangement of the upper and lower blades in the row direction and the column direction may be regularly arranged in a zigzag pattern alternately as shown in FIGS. 1 and 2, but it can be interpreted by randomly arranging them. Can be difficult.

As shown in the cross-sectional view of FIG. 4, the upper blades 4A, 4B, 4C,... Of the upper base 1 are held in a state of being lifted in parallel with the punch object by the lifting spring 7, and the lower blade 3A, It is preferable to descend perpendicular to 3B, 3C. This is because if the blade tip of the upper blade is inclined and descends to the lower blade portion, there is a possibility that the hole is not well opened in the punch target.
Here, the lifting spring refers to a spring having a repulsive force in the upward direction, and it is preferable to use a commonly used coil spring.

  As shown in FIG. 4, since a plurality of rising springs 7 are provided in the upper base 2, after the upper blade is lowered by pushing down the upper surface plate 6, the upper surface plate 6 returns to its original raised state when released. Try to return. Further, the rising spring 7 has a strength with a repulsive force larger than that of the later-described rotating shaft spring, so that the upper blade protrudes as long as the upper base 2 does not contact the lower base 1 even if the upper surface plate 6 is lightly pressed. It becomes a structure that does not take advantage.

  The lower blades 3A, 3B, 3C... Are accommodated in the lower base 1. Further, the upper base 2 provided to face the lower base 1 is pivotally supported at one end by a rotary shaft 8 so that the upper base 2 comes into contact with the surfaces of the lower base 1 and the upper base 2. By pressing the upper part of 2, the upper blades 4A, 4B, 4C,... Can be lowered vertically to open a hole in the punch object, and a safe structure can be obtained in which a finger is not accidentally damaged.

  Thus, in order to have a structure in which the upper blades 4A, 4B, 4C,... Do not descend until the upper base 2 contacts the surface of the lower base 1, for example, as shown in FIG. It is preferable to provide a mechanism in which the rotary spring 17 operates preferentially by providing a rotary spring 17 that is weaker than the ascending spring 7 provided in the upper base 2 on the rotary shaft 8 that fixes 2.

  Here, the rotation spring refers to a spring having a repulsive force in the rotation direction, and a commonly used coil spring is preferably used.

FIG. 2 is a top view illustrating an embodiment of the information leakage preventing punch of the present invention.
In FIG. 2, the range where the upper blades 4A, 4B, 4C,... Are provided is the size of the palm or postcard, depending on the size of the upper blade. It is preferable to make the part unreadable.

  The diameter of the upper blade and the lower blade varies depending on the character and size, but in order to make it unreadable by the punch hole, the diameter of the hole size is preferably 3 mm to 20 mm, and the diameter of the gap between adjacent blades is also The thickness is preferably 3 mm to 20 mm.

  Further, the shape of the blade may be square, elliptical or S-shaped. It is also possible to make the blade diameter partially different within the range of the postcard size.

FIG. 3 is a front view illustrating an embodiment of the information leakage preventing punch of the present invention.
As shown in FIG. 3, by providing a waste bin 5 for collecting waste generated by opening a hole in the punch object below the lower base 1, it can be used as a waste receptacle after the punch. It is possible, and garbage is not scattered.

  The scrap bin 5 is configured to insert scraps removed by punching. Since it is a pull-out type by the handle 18, it is possible to easily discard the scraps that have been pulled out.

  6 to 8 are sectional views of the information leakage preventing punch according to the present invention as seen from the side, FIG. 6 shows a state where the upper base is raised, FIG. 7 shows a state where the upper base is lowered, and FIG. The pressed state is shown.

  6 to 8, since there are a large number of upper blades and lower blades, a considerable amount of force is temporarily required to press the upper surface plate 6 of the upper base 2. Is provided at both ends of the upper base. That is, the upper base 2 has crossbars that are fixed by floating pins at both ends, and when the upper portion of the upper base is pressed, the floating pins 13 slide in the slits 14 provided in the crossbars 10 and 11. As the cross bars 10 and 11 tilt, the pressing force that presses the upper base 2 is reduced.

  Further, the lower part of the cross bar 10, 11 is fixed by a fixing screw 12, and the pressing force is reduced by utilizing this principle as will be described later.

  Moreover, the force required for drilling is reduced by making the timing of drilling the plurality of upper blades and lower blades different from each other. The upper edge of the central part descends in advance of the drilling timing, and the right upper blade and the left upper blade descend with a delay. In order to ensure the deviation of the lowering of the upper blade, it is preferable to set the upper blade that descends in advance to be lower than the upper blade that descends later.

  FIG. 6 shows a state where the upper base 2 is opened, and FIG. 7 shows a state where the upper base 2 is closed. In FIGS. 6 and 7, the upper blade is housed in the upper base, and the upper blade does not come out unless the upper surface plate of the upper base is pressed. Therefore, there is no danger of pinching and cutting the finger. When the punch object 16 is inserted between the upper base 2 and the lower base 1 and the upper surface plate 6 of the upper base 2 is pushed down, the upper blade is lowered. As shown in FIG. 6, since the upper base opens widely, the punch object 16 can be easily inserted.

  FIG. 8 shows a state where the upper base plate of the upper base is being pressed. The ascending spring 7 contracts, and the upper blade descends vertically to fit the lower blade. Further, both ends of the upper surface plate 6 move down the upper surface plate slide space 15 of the upper base and come into contact with the upper surface receiving plate portion 9, so that holes are punched in the punch object, and the hole scraps enter the above-described scrap tray 5. .

  FIG. 9 is a diagram for explaining the operation of the crossbar used in the present invention. FIG. 9A shows the operating state of the crossbars 10 and 11 when the upper base 2 is raised, and FIG. 9B shows the operating state of the crossbars 10 and 11 when the upper base 2 is lowered.

  As shown in FIGS. 9 (a) and 9 (b), the horizontal distance from the fixing screw (fulcrum) 12 to the force point for pressing the top plate 6 is L1, and from the fixing screw (fulcrum) 12 to the action point for pushing down the upper base 2. Since the horizontal distance is L2, and L1 is larger than L2, a force (F2) that is L1 / L2 times the force (F1) that pushes the power point acts on the point of action, so it is necessary to press the top plate 6 On the contrary, the force is reduced to L2 / L1 of the force (F2) acting on the action point.

  When the information leakage prevention punches according to the embodiments of the present invention shown in FIGS. 6 to 8 are applied to a printed matter made of A4 size paper, holes that are easily arranged two-dimensionally even if 10 sheets are punched at once. The effect of the present invention was confirmed.
