Description

  The present invention cuts billing details / receipts containing personal information and confidential matters, other printed materials and documents, cuts recording media such as CDs and DVDs, cash cards, credits, etc. IC cards such as cards are shredded, and at the same time, magnetic recording data is destroyed and erased to prevent the digital data recorded on them from being reproduced, and personal information and confidential matters from waste are prevented from leaking. Therefore, the present invention relates to a shredder device used in an office or home.

2. Description of the Related Art Conventionally, in order to dispose of confidential documents and the like, a shredder device having a structure in which an insertion port is formed on an upper surface of a main body and a shredding cutter is provided inside is provided. In addition, when disposing of a magnetic storage medium such as a flexible disk or a magnetic disk, the shredding device not only shreds them but also arranges a device for erasing the magnetic information remaining in the fine pieces in parallel with the shredding cutter. Is known (see, for example, Patent Document 1).
Japanese Utility Model Publication No. 62-179036

However, the conventional shredder device usually has only one insertion port, and the shredding device described in Patent Document 1 also has only one insertion port on the upper surface of the main body. It is only disclosed.
However, there are multiple types of objects to be shredded, ranging from paper fragments such as confidential documents to magnetic disks and magnetic cards, and these shredded objects are inserted through a common insertion slot and shredded using a common shredding cutter. It is not appropriate if it is a method that is designed to do so.

That is, since the shredding method and required torque differ between different types of shredded objects, the method of shredding them with the same shredding cutter is inappropriate for the size and shape of the shredded pieces (debris) Or torque may be insufficient, which is not appropriate.
For example, since documents need to be shredded as finely as possible, it is necessary to reduce the installation interval of the cutters and use a large number of sheets in a dense arrangement. When trying to shred magnetic disks and magnetic cards, a large drive torque is required. When manually rotating the cutter like a hand shredder, the shredder is especially useful for women and children with weak power. There are cases where it is not possible.

  Further, in the conventional method, in order to enable shredding of documents that do not require erasure of magnetic information, the opening size of the insertion slot is larger than the size of the magnetic storage medium, for example, A4 size to B4. It is necessary to keep the size of the document so that it can be inserted. For this reason, it is necessary to arrange a magnetic information erasing device that is larger (longer) than the size of the magnetic storage medium in accordance with the opening size of the insertion slot, which is wasteful and unreasonable.

  Moreover, although the magnetic information erasing apparatus of the said patent document 1 has illustrated the case where it installed only in the one side of the magnetic-storage-medium path | route between an insertion port and the cutter for shredding, There are some problems. That is, there are magnetic storage media in which the magnetic information storage part is formed on only one side and in which the magnetic information storage part is formed on both sides. It is necessary to align the surface with the side where the magnetic information erasing device is installed, and if inserted in the opposite direction, the magnetic information may not be erased or the erasure may be incomplete. In the case where the information storage part is formed on both sides of the medium, only one side is erased, and the other side may not be erased or the erasure may be incomplete.

  The present invention has been proposed in view of the above-described problems, and the object of the present invention is to set the shredding size and shredding torque within an appropriate range for each type of shredding object. It is an object of the present invention to provide a shredder device that can reliably erase magnetic information.

In order to achieve the above object, the present invention divides and arranges a document insertion slot, a magnetic disk insertion slot, and a magnetic card insertion slot on the outer surface of the upper lid of the main body supporting the shredding cutter. In addition, a pair of magnets are arranged opposite to each other with a gap passing through the cards between at least the magnetic card slot and the shredding cutter.
According to the above configuration, documents, magnetic disks, and magnetic cards can be selected and shredded using the optimum shredding method and shredding torque for each, and magnetic information can be used regardless of the insertion direction. At the same time, it can be surely destroyed or erased. In particular, in the case of a medium in which the magnetic information storage unit is formed on only one side, the surface may be inserted in either direction, and even if the surface is formed on both sides, the magnetic information is reliably obtained. It can be destroyed or erased.

The magnetic card insertion slot has a rectangular opening slightly larger than the short side length and the thickness of one sheet of the magnetic card, and the pair of magnets has a length corresponding to the magnetic card insertion slot. The pair of magnets are arranged to face each other with a card passage gap slightly larger than the thickness of one magnetic card.
According to the above configuration, regardless of the position of the magnetic information storage unit in the magnetic card, the magnetic cards are inserted one by one along the long side direction, and both surfaces are passed close to the magnet. It is possible to reliably destroy or erase the magnetic information of the magnetic cards.

  The document insertion slot has a rectangular opening shape into which a plurality of A4 size or B4 size pieces of paper can be inserted from the short side, and the magnetic disk insertion slot and the magnetic field are adjacent to the document insertion slot. The card insertion slot is arranged in parallel and on the same straight line, and the shredding cutter is provided corresponding to each of the document insertion slot, the magnetic disk insertion slot, and the magnetic card insertion slot. It is characterized by.

  According to the above configuration, the documents can be shredded to A4 size or B4 size, and the magnetic disk insertion slot and the magnetic card insertion slot can be arranged side by side within this horizontally long dimension range. Three types of insertion openings can be arranged in a compact and rational manner on the top cover of the main body, and the cutting lines for the other two insertion openings are arranged adjacent to the shredding cutters for the document insertion openings. It can be arranged in parallel, and in particular, the shredding cutter for the magnetic disk insertion slot and the shredding cutter for the magnetic card slot can be arranged in series on the same axis, so each shredding cutter is driven. The force transmission mechanism can also be made compact and compact. Moreover, since the object can be shredded into documents, magnetic disks, and magnetic cards, it can be shredded to the optimum size and shape for each object, and the rotational drive torque is within the proper range. Easy to set.

The shredding cutter can be driven to rotate by a manual handle.
According to the above configuration, documents, magnetic disks, and magnetic cards can be shredded without using power such as electricity.
The shredding cutter provided corresponding to the document insertion slot has a cross-cut structure that cuts the documents perpendicular to two directions, and is provided at the magnetic disk insertion slot and the magnetic card insertion slot. Correspondingly provided shredding cutters are characterized by a straight cut structure that shreds in one direction.

  According to the above configuration, the documents are shredded perpendicularly to the two directions, and the magnetic disks and magnetic cards are shredded in a band shape in one direction.

  ADVANTAGE OF THE INVENTION According to this invention, the shredder apparatus which can set a shredding dimension and shredding torque to an appropriate range for every kind of shredding object, and can erase | eliminate magnetic information reliably can be provided.

Embodiments of a shredder apparatus according to the present invention will be described below based on the drawings.
