Description

[0001] Punch type paper crusher [0002]

The present invention relates to a document shredder, and more particularly, to an improvement of a punch type document shredder for shredding documents using punching pins.

With the rapid transition from the industrial society to the knowledge society and the information society, the harm caused by information leakage is getting serious. Accordingly, it is increasingly necessary to dispose of various kinds of data, such as a document requiring security which is generated in a public office, a company office or a home, or a card invoice showing personal information, after being shredded by a document shredder or the like.

As a result, the use of paper shredders has been generalized to such an extent that document shredders such as document shredders must be used not only in public institutions and companies but also in ordinary households. However, it is still difficult to buy electric shredders in small individual businesses or households.

In addition, the conventional electric shredder is convenient to use but requires power, and power consumption due to standby power occurs in standby state. This is in line with government policies that seek energy efficiency.

Conventionally known document shredders include a method in which a document is heated by rotating a rotary blade by a motor, a method in which a document is heated by turning a rotary knife by a hand, and a method using a punching method. Except for the punching method, it is possible to process only one document at a time, and it takes a lot of time to shred several documents.

And it is convenient to rotate the rotating blade by the motor, but it has a disadvantage that it has a high probability of failure, is difficult to use for a long time, consumes power, and is limited in installation place for power connection.

In addition, the method of rotating the rotary knife by rotating the handle by hand causes the document to be heated, which is time-consuming because the handle must be rotated several times by hand, which is inappropriate for use when the number of documents to be shredded exceeds several thousand.

The present invention relates to a document crusher using a punch method capable of crushing a plurality of documents, and related prior art is disclosed in Japanese Patent Application Laid-Open No. 4-61937 (hereinafter referred to as "prior invention"). The prior art discloses an apparatus comprising a main body having a box and a lower plate having a main body and a lower plate on which an upper plate on which a punch projection is formed and a hole into which a punch projection is inserted are formed by elastic support by a support bar and a spring. This prior art is advantageous in that, since a plurality of sheets can be manually shredded at one time in comparison with a method of cutting a document by rotating a rotary blade, the shredding efficiency is excellent without waste of electric power.

The inventor of the present invention has the advantage that it is possible to crush a plurality of documents at a time without waste of electric power, but whenever the crushing of a document is performed, the residue after punching remaining between the upper plate and the lower plate is hand- It is necessary to carry out a document crushing operation again. Therefore, it is recognized that there is a problem that the crushing operation efficiency is lowered.

In addition, the prior art has a problem that it takes a long time to break the document and there is a great risk of a safety accident when the post-punching residue is manually taken out by hand.

In addition, the prior art is disadvantageous in that it is unsuitable for use in the home, and occupies a too large area in the office, since the document is laid down and crushed and occupies a large area.

In addition, in the prior art, a safety plate extending downward from the upper plate along the edge of the upper plate is provided for the safety of the user so that a plurality of sheets can be inserted between the upper plate and the lower plate, In such a case, it is more difficult to remove the residue after punching, which makes it difficult to install the safety plate.

It is an object of the present invention to provide a document shredder suitable for use in a home or office having a small space and a small space so that not only a plurality of documents can be shredded at a time.

Another object of the present invention is to provide a document shredder which is capable of easily removing residues after punching a document, and is superior in the efficiency of crushing a document as compared with the conventional art.

Another object of the present invention is to provide a document shredder which can easily remove residues after punching of documents even if a safety plate is installed.

It is still another object of the present invention to provide a document shredder which is easy to manufacture, low cost, and does not break down and is easy to repair even if a trouble occurs.

A document shredder according to the present invention is a document shredder for use in punching and crushing a document, the document shredder comprising: a container body having an opening formed thereon; A support portion provided with a plurality of punching holes and extending upward from above the support body and having a lower portion opened toward the opening; And a plurality of punching pins inserted into the punching holes at positions facing the punching holes to pierce a plurality of holes in the document between the punching holes and the punching hole, A punching member rotatable relative to the support portion; A residue releasing member provided between the punching member and the receiving portion and having a hole through which the punching pins can pass, and allowing a document inserted into the punching pin to be released from the punching pin after punching; The punching pin is rotatably installed on the main body to support the lower end of the document inserted between the receiving portion and the releasing member, and rotates after punching to rotate the punching pin so that the residue can fall into the container. A support member; And support member operating means connected to the support member for pivoting the support member to a position for supporting the document before punching and to a position for allowing the residue to fall down to the container body after punching .

It is preferable that one of the support portion and the punching member is fixed to the support body and the other is rotatably installed on the support body or the one fixed to the support body.

It is preferable that at least one of a thermometer and a hygrometer is installed in the document crusher.

It is preferable that a drawer-type auxiliary container is installed in the above-mentioned container body.

It is preferable that a transparent window for confirming the internal state is installed in the container body.

It is preferable that a hook is provided on the back surface of the receiving part so as to be hooked to a ring or a structure provided on the wall.

Since the document shredder according to the present invention can also shred several sheets at a time, it is possible to reduce the time required for document shredding and to punch the document in a standing state, thereby taking up a small horizontal area.

Since the document shredder according to the present invention is small in thickness, it can be constructed as a wall-mounted type that can be used by hanging on a wall.

The document shredder according to the present invention is convenient because it can remove the document residues remaining between the receiving unit and the punching member after punching directly to the container below.

In addition, according to the present invention, it is possible to easily remove document residues even when a safety plate is installed, so that there is no restriction on the installation of the safety plate, and as a result, the risk of a safety accident can be reduced.

Since the conventional electric type crusher is expensive, it is burdensome for an individual individual to purchase the crusher, but the document crusher according to the present invention can provide a document crusher having a superior ability to crush a document at a much lower price.

Although the conventional electric shredder is accompanied by unnecessary power consumption due to standby power and the repairing cost is high in case of failure, the document shredder according to the present invention does not require electric power, so it meets the green environment and does not fail well, Repair costs are low.

In the conventional electric type crusher, the paper is occasionally caught in the crushing state and the electric power is consumed. However, in the document crushing apparatus according to the present invention, there is no consumption of electric power and the paper is not caught.
