[0001] SHREDDERS FOR PAPER [0002]

The present invention relates to a document shredding apparatus, and more particularly, to a document shredding apparatus comprising means for confirming a document to be shredded while integrating the authentication means in a document shredding unit, and means for separating the identified document, Means for preventing a document that is not to be discarded due to carelessness from being shredded and for confirming whether or not the document to be discarded has been normally discarded to enhance the security and management of the discarded document To a document crushing apparatus.

Various security incidents are occurring because documents requiring security are leaked to the outside without the formal approval or procedure. In particular, documents requiring security include important information such as companies and public institutions, and therefore there is a loss of business and business, such as property damage or strategic exposure.

As a result, companies and public organizations are strengthening the security of documents that are shredded by outside personnel, and they are increasing security education for their employees.

However, there is a limit to prevent documents from being destroyed abnormally by security education alone.

A common method for shredding a document is to shred the document using a document shredder. Accordingly, various types of document shredders have been introduced.

In the early days of document shredders, they were simply crushed when documents were put in. These documents do not have the means to recognize, store and screen documents so that once the documents are inserted, they should not be discarded, or if the shredding is to be held by instant remorse, the contents of the document Unidentified sedans and crushing proceed without confirmation, resulting in unrecoverable consequences.

On the other hand, a large amount of documents stored for a certain period of time in accordance with the business regulations should be designated as discarded documents and discarded. In order to check whether the documents to be discarded are stored and not discarded, There is a difficulty.

In addition, according to the business regulations, a large amount of documents stored for a certain period of time is designated as a waste document, the waste disposal process is referred to the subcontractor, and the subcontractor records the document to be discarded, There is a possibility that an accident may occur, and there is a problem that it is impossible to confirm whether or not a normal disposal has actually been performed.

Accordingly, various types of document shredders have been introduced to prevent documents from being shredded without normal permission, and to prevent documents from being leaked out due to carelessness.

For example, Korean Patent No. 10-1656073, entitled " Security Enhancement Device for Document Sedan Machine ", comprises authentication means installed to generate a signal for authentication with an illuminance sensor, And control means for controlling the output to the shredding apparatus corresponding to the input of the apparatus and the authentication means.

Wherein the authentication unit further comprises a camera for acquiring a user image and a card reader for reading an identification card to process authentication with a plurality of inputs, wherein the shredding device comprises: a scanner for converting contents of the object into digital data; And a storage box installed at a lower end of the chute to store an object to be bypassed, wherein the control unit is provided with a touch screen And a fracture pad for guiding bypass of the object when the extracted keyword matches the data of the scanner.

The security enhancing device of the document shredder recognizes the RFID information of the face recognition or the employee ID so that the employee is authenticated as a member and then the document is discarded in a batch manner.

Therefore, if there is a need to discard documents that are not to be discarded or to dispose of the shredding, there is still a problem in the use of unilateral sedans and crushing that can not be confirmed.

In addition, since the shredded document can not be systematically managed as a database, it can not be confirmed whether the destruction target document is not discarded and stored, and it is not possible to confirm whether or not the destruction target document is normally discarded, There is a problem with this.

The operation of the embodiment of the present invention will be described below.

First, in the case of the first embodiment, as shown in FIG. 1, the document discharged from the paper feeder 2 is used to generate document information and a document image via the image generating means 4, (7) and crushed, and the crushed waste is stored in the collection box (8).

Here, in the case of a secure document obtained by reading the document recognition means of the shredding request document by the image generation means 4, the document information is stored in the control means 6, and a non-secured document or a general document The control unit 6 displays an image of the document and simultaneously inputs information about the document.

The input of the information on the document is enabled by a keypad or a touch screen provided in the control means 6 and the inputted document information and the document image obtained by the image generating means 4 are input to the control means 6 ).

2 and 7, the document shredding apparatus is provided with the authentication means 3 for identifying the identity of the document shredding requester. When the identity of the document shredding requester is authenticated, A shredding request document placed on the tray 2 by the drive signal of the control means 6 is transferred to the image generating means 4 to generate document information and a document image, 10 to the crushing section 7 and crushed, and the crushed crushed material is stored in the collection box 8.

As a result of reading the document recognition means of the shredding request document by the image generation means 4, the processing procedure for the secure document and the general document is the same as that of the first embodiment.

That is, when the shredding request document is a security document, the document information is stored in the control means 6. If the shredding request document is a non-security document or a general document without the document identification means, the control unit 6 displays an image of the document And information on the corresponding document can be input by a keypad or a touch screen provided in the control means 6, and it is possible to input information about the general document, The document image obtained in the means (4) is stored in the control means (6).

The driving of the roller device 10 is the same as the third to fifth embodiments described later, and will be specifically described in the following embodiments.

As shown in FIG. 7 to FIG. 14, in the case of the third embodiment which is referred to in FIG. 3, without the authentication means for identifying the identity of the document shredding requester in the document shredding apparatus, 2 is loaded on the intermediate stacking table 5 via the image generating means 4. The image forming means 4,

At this time, the image of the document generated by the image generating means 4 is displayed on the display means 60 constituted by the touch screen through the control means 6, and at the same time, an input window for selecting the shredding and discharging routines It is displayed on the touch screen.

Thereafter, the document shredding requester can check the status of the document displayed on the display means 60 and determine whether the shredding and non-shredding ejection is possible.

Here, if the document image generated by the image generating means 4 is a document to be shredded as a result of being displayed on the display means 60, the control means 6 performs the shredding routine of the document, The control means 6 does not perform the shredding routine of the document but performs the discharging routine.

The drive roller 101 of the take-out roller 100 starts to drive and the take-out roller 102 supports the drive roller 101 so that the center of the take- And the document is transported from the loading table 5.

Each time the movable piece 123a makes contact between the first limit switch 123b and the second limit switch 123c, the switching signal switches the rotation of the second motor 120 in the normal and reverse directions, I repeat.

That is, the document expanding means 12 is driven every time a single document is fed, and when the folded document is present in the process, the folded portion is extended so that the document is not caught by the pulling roller 100, And the take-out roller 102, as shown in Fig.

Here, the first sensor 141 senses the document, and the second sensor 142 and the third sensor 143 detect that there is no document, and the document expanding means 12 is driven.

When the second sensor 142 and the third sensor 143 detect a document, the document expanding means 12 is in a driving standby state.

The document to be fed through the drawing-out roller 100 is spaced apart from the driving roller 101 at a predetermined interval, preferably a space at which a single document can pass, The one document positioned at the bottommost position by the roller 100 is ejected by the guide roller 104. [

At the same time, the separator 11 rotates the rotating shaft 112 within a predetermined angle range by the third motor 110 so that the upper end of the rotating piece 113 is separated from the driving roller 101 of the drawing roller 100 So that the document discharged into the space can be guided by the guide chute 131 to reach the crushing part 7. [

The guide chute 131 is provided with a conveying roller 132 at an appropriate interval so that the document can easily reach the crushing section 7.

The shredding request document arriving at the shredding section 7 is immediately dropped into the crushing section 7, is shed and crushed, and then the shredding document is stored in the collection box 8.

If the document image generated by the image generating means 4 is not displayed as a result of being displayed on the display means 60, or if the document is not to be shredded, the document shredding requester is displayed on the touch screen of the display means 60 The third motor 110 of the separator 11 is driven in the opposite direction and the rotation shaft 120 is rotated in the reverse direction within a certain angle range, The upper end of the take-up roller 130 comes close to the drive roller 101 of the take-out roller 100.

Accordingly, the document discharged from the guide roller 104 is not introduced into the guide chute 131, but is guided to the upper surface of the rotating piece 113 and is introduced into the discharge box 9, .

At this time, the drive roller 101 of the take-out roller 100 starts driving, the take-out roller 102 supports the drive roller 101 to transfer the document from the intermediate stacking bed 5, The process of feeding a document by the paper feed roller 103 and the guide roller 104 is performed as described above with reference to FIG.

In the case of the fourth embodiment which is referred to in Fig. 4, as shown in Figs. 8 to 14, the document shredding apparatus is provided with the authentication means 3 for identifying the identity of the document shredding requester. When the identity of the document shredding requester is authenticated, The shredding request document placed on the tray 2 by the drive signal of the control means 6 is transferred to the image generating means 4. [

The process of discharging from the image generating means 4 and the operating state are the same as those of the third embodiment, so repeated description will be omitted.

In addition, the server 15 is networked with a separate printing system, and information on the document identification means of the security document printed on the printing system is stored.

Therefore, when the identity of the document shredding requester is recognized in the authentication means 3, the authentication history is stored in the server 15, and a driving signal that follows the authentication of the document shredding requester is sent from the server 15 via the control means 6 And sends the shredding request document placed on the tray 2 to the image generating means 4. [

In this way, the shredding request document placed on the tray 2 by the drive signal of the control means 6 is transferred to the intermediate stacking table 5 via the image generating means 4, The document information of the shredding request document is transmitted to the server 15.

The server 15 compares the information about the document identification means of the security document stored while being printed in the printing system with the document information obtained by the image generation means 4 and judges whether the document stored in the intermediate stacking bin 5 Is displayed on the display means (60) of the control means (6) so as to determine whether to perform the discharge or shredding routine.

The operations of the roller device 10, the separator 11 and the crushing section 7 according to the discharge or shredding routine are the same as those of the above-described first to fifth embodiments, and thus repeated description will be omitted.

On the other hand, it is also possible that the image data and the document information of the document shredding requestor performed through the authentication means 3, the image and document information of the shredding request document generated by the image generating means 4, The document information and the shredding result of the shredding request document by the shredding unit 7 are stored in the server 15.
