Abstract

<P>PROBLEM TO BE SOLVED: To secure a size of a fiber of paper in a residual part and facilitate a recycle to a high quality form by cutting only a part requiring cutting step in a form which carries confidential information or the like. <P>SOLUTION: A small-diameter drilling device incorporates an optical reading device and an operating device which allows the reading result to be image-processed. A part to be cut in the form is recognized from the result of image processing operation and is drilled by the drilling device, so that a part which does not require cutting is made to remain as a paper piece as large as possible. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a method for cutting confidential documents and the like.

Conventionally, it has been a method of cutting an entire confidential document sheet into an elongated or strip shape.
Japanese Laid-Open Patent Publication No. 2000-188833

  Finely cut paper is not suitable as a raw material for high-quality recycled paper, and there is a problem that it is often incinerated at present.

  However, the idea that an ever-increasing recycling rate of paper is inevitably required in response to various environmental issues is seen as a common philosophy.

  Therefore, as a method of using confidential documents as raw materials as recycled paper, a confidentiality agreement is concluded with a business operator who carries out recycling business, and then it is delivered in a hermetically packed state and dissolved without opening. In addition, companies that carry out recycling businesses come with vehicles that have built-in large-scale equipment that performs dissolution processing into paper raw materials, and methods such as processing confidential documents on the spot are now being carried out. .

  However, delivery in a sealed package has an information security problem that cannot completely prevent accidents, human error, or leakage of secrets by malicious persons. The dissolution treatment by moving has a problem that it is very expensive.

  The present invention has been made to solve the above-described problems, and automatically selects and cuts only a portion that requires cutting processing in a confidential document, and secures a fiber size as much as possible for a portion that does not require cutting. It remains in a state and can be used as a raw material for high-quality recycled paper.

  First, a sheet to be cut is read by an optical reading unit, and a portion that requires cutting processing is selected by an image processing calculation and control unit. Next, the part which needs a cutting process is cut finely by punching with a drilling blade. By putting the cut waste and the remaining paper portion into separate containers, it is possible to take out the portion that does not require cutting and use it as a raw material for high-quality recycled paper.

  If the apparatus (hereinafter referred to as this apparatus) according to the confidential document processing system of the present invention is used, after cutting without leaving it to the hands of a third party, only parts that do not require cutting are used as recycled materials. As a result, the security of confidential information is ensured within the reach of the parties' eyes, and the recycling can be handled.

  In addition, by having an optical reading device, it is possible to connect a personal computer or the like to the device and save it as image information at the same time as cutting, and automatically digitize and cut documents. There is also an effect.

  Furthermore, the problem with conventional cutting devices, such as “the wrinkles are not cut and the volume is bulky if not compressed,” can be solved by the fact that the cutting pieces of this device do not wrinkle, and the cutting waste storage section The frequency of taking out the food is greatly reduced, and the convenience of the user is greatly improved.

  Hereinafter, an embodiment of the present invention will be described with reference to FIG.

  In FIG. 1, the cutting required paper 2 is placed on the paper stock unit 1 so that the cutting required information faces a surface that can be read by the optical reading unit 4, and processing is executed.

  This apparatus includes at least one or more optical reading unit 4, and includes an image processing calculation and control unit 5 and a punching blade 7 for cutting, and separates and collects cutting waste 8 and remaining paper 10 after cutting. A cutting waste storage unit 9 and a remaining paper storage unit 12 are provided.

  In FIG. 1, the cutting-needed paper 2 placed on the paper stock unit 1 is sent to the reading position of the optical reading device 4 by a paper feed roller 3.

  The optical reading device 4 reads the image information on the paper and sends it to the image processing calculation and control unit 5. The image processing calculation and control unit uses a predetermined algorithm to determine a portion that requires cutting of the paper, feeds the paper to the position of the punching blade 7 by the paper feed roller 6, and punches only the portion that requires cutting.

  The cutting waste 8 accumulates in the cutting waste storage unit 9, and the remaining paper 10 after cutting that has not been cut is fed into the residual paper storage unit 12 by the paper feed roller 11.

  FIG. 2 is an example of a portion of the piercing blade as seen from above, and the piercing blade is attached in a plurality of rows, and a plurality of times are cut for a region that requires cutting, Realize necessary and sufficient cutting.

  In FIG. 3, by providing a plurality of the optical reading units so that both sides of a sheet can be read, even a sheet printed on both sides is appropriately determined and cut by punching a portion that needs to be cut.

  In FIG. 4, by providing a mechanism for reversing the front and back of the paper, even a double-sided printed paper, a portion that needs to be cut is appropriately determined and cut by punching.

  In FIG. 5, by providing a connection interface with a personal computer or the like, the function of storing as electronic data is performed, and at the same time, the part that needs to be cut is appropriately determined and cut by punching.

  In FIG. 6, cutting is performed by punching at an arbitrary position in the moving direction by a movable head having a small number of punching blades.

  It is a figure which shows the internal structure of embodiment of this invention.   It is a figure which shows the structure of the drilling blade part of Example 1 of this invention.   It is a figure which shows the internal structure of Example 2 of this invention.   It is a figure which shows the internal structure of Example 3 of this invention.   It is a figure which shows embodiment of Example 4 of this invention.
