Abstract

PURPOSE:To easily make the image of a document unreadable and to miniaturize a storage space, by applying opaque paint to the whole of a single surface or both surfaces of paper by a coating means and storing the same in such a state that the coating surface thereof is closely adhered. CONSTITUTION:In the disposal of a secret document, the paper inserted from a paper insert port 2 is guided between rollers 4, 5 by the rotation of a paper feed roller 3, and the opaque paint supplied from felts 6, 7 provided so as to contact the peripheral surfaces of rollers 4, 5 is applied to both surfaces of the paper. Thereafter, the paper is guided to a storage part 11 by a guide 13 and stored therein in such a state that the surface thereof is closely adhered with the surface of the paper already stored in the storage part. The papers when filled are taken out of the storage part 11 by opening the door 9 which is closable.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Use This invention relates to an image erasing device for disposing of documents while keeping the written contents secret.

(b) Conventional Technology A shredder has traditionally been used to dispose of documents containing secret documents and drawings, making them unreadable. This shredder places paper sheets between a large number of pairs of rotating blades installed on the top and bottom, and shreds them (1).At the same time, images are shredded to make them unreadable, and documents 9, etc. are disposed of in a concealed state. (c) Problems to be Solved by the Invention In the conventional shredder as described above, in order to ensure that documents written on documents are made illegible, the distance between the rotary blades in the axial direction must be narrowed. Each time you do this, you shorten the cutting width of the paper. However, shortening the cutting width means increasing the number of rotary blades that come into contact with the paper, and the required rotational torque increases due to the increase in rotational resistance. This has the disadvantage of requiring a larger motor, which leads to problems.

Furthermore, for the same reason, the amount of dust associated with cutting increases, and the frequency of machine failures increases. Furthermore, cut paper occupies more voids in the same volume than before cutting, so it has the disadvantage that it requires a large space for storage.

The purpose of this invention is to make documents, etc. written on them unreadable without misalignment, to prevent the motor from becoming larger due to the narrowing of the cutting width, an increase in the amount of dust, and an increase in the force of the gap during storage 1). Solving problems and causing cost problems and breakdowns 41
-An object of the present invention is to provide an image erasing device that can realize low frequency and space saving.

(Means for solving problem d1) The image erasing device of the present invention; 6. Applying opaque coating 1 to one side 7 or both sides of the paper fed through the paper 1 feeding path. A) Paper storage means for storing the paper that has passed through the coating 41-meshing step in the direction of the paper surface, and the tray (
Ii! i: Let λ-tagoto be '1j [sign.

According to the invention of te+ A'1y, -, the entire surface of one or both sides of the paper is coated with an opaque paint by a coating means. Further, the paper coated with the coating 1 is stored in the paper storage means with the paper surface 1) in close contact with the paper.

(f) Embodiment FIG. 1 is a schematic diagram of side 1 without showing the structure of an image erasing device according to an embodiment of the present invention.

Front panel of the image erasing device body 1. -1 is formed with a paper insert 1-12, and a boop pull 2a is attached thereto. Picture 13 - Inside the forming device main body 1, the chiffle 2a
U)k2 has paper feed I)-ra3 (liti).

Furthermore, a guide 1) 0a faces the tables 2, 1, forming a conveyance path 10. A pair of rollers 4 and 5 are in contact with the inside of the image erasing device main body 1 with a constant pressing force.

The rotation of the motor outside the country is transmitted to the -ra 4. l-
The 1-roller 5 is pressed against the roller 4 and rotates 7 by rotating the 1-roller 4 by one inch. A felt 6.7 is in contact with each of the rollers 4, 5.

The felts [3, 7 supply the ink stored in the tank 8 to the circumferential surfaces of the rollers 4, 5. The paint stored in tank 8 is an opaque paint. 2 rollers 4 and 5
and felt 6.7 are the application means of this invention.

The conveyance path 10 is continued downward from the rollers 4 and 5 by a guide 13. The upper side of the image erasing device main body 1 is the storage section 1.
), the paper passing through the rollers 4 and 5 falls downward as shown by the broken line in the figure, and the paper 12 is stored in the storage section 1' with the paper surface in close contact with the cage. this! 1) A paper storage means according to the invention including a clasp 1) and a kite 13.

A part of the front pile of the image erasing device main body I is made into an opening/closing door 9. The door 9 can be opened and closed using the lower side as a hinge.
``I is in the state shown by the dotted chain line in the middle of M.

The second figure 1 is a partially cutaway perspective view -C showing the main parts of the image erasing device.

II-One end fi of the fer l-6, 7 that contacts the la 4,5
a, 7a are inserted into the tank 8 through the opening 8a 2). The immersion pressure of the opaque coating 1" 3L and felt 6.7 stored in the dirt removal tank 8 is 1.
The lij portions 6a and 7a move to the contact portion with the ji 1-ra 4 and 5.

According to this embodiment, the paper inserted from the paper insertion [12] is rotated by the rotation of the paper feed roller 3.
It is led between Riji J-So 4 and 5. This roller 4.5 rotates in the directions of arrows A and Y3], and
:1-, its circumferential surface is covered with opaque h2 from felts 16 and 7.
1'1 is being fed (Jt). Therefore, the paper is being fed by roller 4.
．． 5, the opaque paint is applied to the entire surface of both sides of the paper by the +1)--ra 4 and 5. After that, the paper is guided to the storage section 1 by a gar (1" 13), and is stored with the surface of the paper in close contact with the surface of the paper already stored in the storage section 1).Storage section When the paper becomes full in step 1), the opening/closing door 9 is opened and the paper is taken out from the storage section 1).

(g+ Effect of the invention According to this invention, an opaque paint is applied to the entire surface of one or both sides of a sheet of paper inserted into the device by a coating means, making the image of a document, etc. formed on the sheet of paper unreadable. Therefore, there is no need for excessive torque when contacting the paper, and there is no increase in cost due to an increase in the size of the motor.Furthermore, for the same reason, when processing
ζ No dust is generated and the frequency of mechanical failures can be reduced. ;j: In addition, since the sheets of paper with images erased are stored with their surfaces in close contact with each other, no voids are created in the sheets during storage, and the storage space can be reduced in size.
