Description

  The present invention relates to a stamping device using stencil printing, and is intended for important documents that need to be distinguished from counterfeits by imprinting a set genuine original stamp, such as financial statements and books, for example, The present invention relates to a stamping device that can automatically stamp an original stamp.

  In recent years, computerization of documents has progressed, and various important documents have been transferred from paper media to electronic media due to the establishment of the so-called e-document method (electronic document method). The e-Document Law, which was enacted in November 2004 and came into effect from April 2005, permits the digitization of documents that must be preserved under certain requirements. However, financial statements, books, contracts with provisions other than standard terms and conditions, receipts of 30,000 yen or more, etc. are not permitted to be digitized by this law, and must still be kept as paper documents. Don't be.

  In that case, it is necessary to stamp the paper document to be stored with an original stamp that proves that it is the original document, and to objectively visualize its authenticity. The following Patent Documents 1 and 2 are known as conventional stamp apparatuses that can be used as original stamps.

  Patent Document 1 describes a stamp creation apparatus. In this stamp making apparatus, a desired image is formed on a film fed from a roll by a thermal transfer ribbon and a thermal head, and the film on which the image is formed is positioned on a stamp surface forming member of a stamp body set at a predetermined position, and a xenon tube The stamp surface forming member of the stamp body is irradiated with light emitted from the stamp body through a film, and the stamp surface forming member is selectively melted to form a stamp image. The used film is sent first and stored. According to the stamp manufactured by this apparatus, an image can be printed by the user holding it in his hand and pressing the stamp surface against the document with an appropriate force.

  Patent Document 2 describes a stamp device. This stamp device has a roll of unused stencil paper and a roll of used stencil paper inside the main body, and the stencil paper is continuous between them, and the ink impregnated stamp means is arranged in the middle ing. Then, the stencil sheet fed from the unused roll is made by an external plate making means, and the plate making portion to be a printing surface is arranged directly below the stamp means. According to this stamp apparatus, an image can be printed by the user holding it in his hand and pressing the stamp surface against the document with an appropriate force.

  According to the conventional stamp apparatus, the amount of ink transferred from the plate to the paper is determined by the time when the plate and the paper are in contact with each other, and this affects the state of the imprint such as density. However, since the stamp apparatus as disclosed in Patent Documents 1 and 2 is manually stamped, the imprint state is not constant. For example, the appearance of the same mark may vary greatly depending on the person who uses it. Even when a person stamps, it may not always be stamped in the same state.

  When such a stamp is used as the above-mentioned original stamp, the original stamp is not determined to be stamped once on a single manuscript, and one certifier can make multiple types of manuscripts on the date of the day. There may be a case where the same original stamp is stamped, and a case where a plurality of different certifiers respectively stamp the same original stamp on a plurality of types of documents on the date of the day. In either case, there was a problem that if the original was manually stamped, the imprinted state would not be the same and the authenticity of the original could not be guaranteed.

  The present invention solves the above-mentioned problems, and is intended for an important manuscript that needs to be distinguished from a fake by imprinting a genuine certification stamp (original stamp). It is an object of the present invention to provide a stamping device that can automatically perform stamping under appropriate stamping conditions so as to achieve the above-mentioned seal impression.

A paper supply unit for supplying a document to be stamped with the certification mark;
A stamping unit that stamps the certification mark on a document supplied by the paper feeding unit using a plate of the certification stamp made on the stencil sheet by the platemaking unit;
A stencil sheet used for printing the certification stamp in the stamp part, and a stencil sheet storage unit wound and stored in a roll in a continuous state with the stencil sheet of the unused plate storage part;
It is characterized by comprising.

The stamping device according to claim 2 is the stamping device according to claim 1,
The stamping unit is configured to hang a stamp roller impregnated with ink on which a stencil sheet made of paper is impregnated, and a document supplied from the paper feeding unit, which is movably disposed in the vicinity of the stamp roller, on the stamp roller. And a pressing member that presses the rotated stencil sheet.

The stamping device according to claim 3 is the stamping device according to claim 2,
The stamp roller includes an internal ink holding portion that stores and holds ink, an ink supply portion in which a large number of ink supply holes are formed in the peripheral wall, and ink that is wound around the peripheral wall and supplied from the ink supply portion And an ink holding portion for impregnating and holding the ink.

  According to the stamping device described in claim 1, the conveying means pulls the unused roll-shaped stencil sheet from the roll of the unused plate storage unit and sends it to the plate making unit, where the plate of the stamp (seal) is printed. Plate making. The plate of the proof stamp made is sent to the stamping portion, and the stamping portion stamps the proof stamp on the document sent from the paper feeding unit using the proof stamp plate. After the stamping is finished, the used certification mark is sent as it is by the transport means, wound in a roll shape in a continuous state, and stored in the stamped plate storage unit.

  Thus, after making a roll-shaped unused stencil sheet automatically and further automatically printing, the stencil sheet is wound and stored as a used stencil sheet in a continuous state, The stamping operation of the certification stamp is efficient and uniform, and the certification stamp imprinted on the document becomes a fixed impression and has little variation. Therefore, even if the same certification stamp is stamped on a large number of manuscripts, and even when many users use the same original stamp, the stamped state of the large number of certification stamps is made constant. be able to.

  The stencil sheet is a sheet formed by sticking a heat-melting film to a porous support such as Japanese paper or candy, and when the film is heat-pierced with a desired original pattern to make a plate, it is particularly solid. Since the irregular pattern of the porous support appears as a unique pattern in a part, the authenticity of the certification mark can be more easily identified and counterfeited particularly in the case of a stamping device that can always keep the stamped state as in the present invention. It becomes difficult.

  According to the stamping device described in claim 2, in addition to the effect of the stamping device according to claim 1, the stamping portion is further impregnated with an ink around which the stencil sheet is made, and the stamping roller.

  As shown in FIGS. 1 and 2, a first transport roller 9, which is a transport unit for the stencil sheet 4, is provided at a position downstream of the plate making unit 6 in the transport direction of the stencil sheet 4. The first conveying roller 9 is configured to pull the stencil sheet 4 made by the plate making unit 6 in the horizontal direction and guide it to a lower stamping unit 10 described later.

  As shown in FIGS. 1 and 2, the stamping unit 10 is provided downstream of the first conveyance roller 9 and below the first conveyance roller 9 in the conveyance direction of the stencil sheet 4. The stamping unit 10 includes a stamp roller 11 on which a stencil sheet 4 that has been impregnated with ink and is engraved is wound around the lower half circumference, and a pressing member 12 that is disposed below the stamp roller 11 so as to be movable up and down. ing.

  As shown in FIG. 3, the stamp roller 11 is a hollow cylindrical member. As shown in FIGS. 3 and 4, the hollow inner space of the stamp roller 11 is an ink storage portion 13 filled with the supplied ink, and the rigid peripheral wall has a large number of fine ink supply holes. Is formed as the ink supply unit 14. An ink holding portion 15 that is a porous soft layer that impregnates and holds ink is wound around the outer periphery of the peripheral wall. Ink is always supplied to the ink storage unit 13 by a pump (not shown), and a constant pressure is maintained. The ink in the ink storage unit 13 oozes out from the ink supply hole of the ink supply unit 14 and impregnates the ink holding unit 15 to be used for printing.

  As shown in FIG. 2, the pressing member 12 has a rectangular parallelepiped shape having a longitudinal direction parallel to the axial direction of the stamp roller 11 and having a dimension comparable to the diameter of the stamp roller 11 in the direction orthogonal to the coaxial direction. For example, urethane rubber. The pressing member 12 lifts a document fed at a predetermined timing between the stamp roller 11 and the pressing member 12 at the lowered position by a lifting drive means (not shown) and presses the original against the stencil sheet 4 of the stamp roller 11. Then, the original is stamped on the original.

  As shown in FIGS. 1 and 2, a second transport roller 16, which is a transport unit for the stencil sheet 4, is located downstream of the stamp unit 10 and above the stamp unit 10 in the transport direction of the stencil sheet 4. Is provided. The second conveying roller 16 is configured to pull the stencil sheet 4 used in the stamping unit 10 vertically upward, draw it out in the horizontal direction, and guide it to the stamped plate storage unit 17.

  As shown in FIG. 1 and FIG. 2, the stamped plate storage unit 17 includes a used stencil sheet 4 used for printing the original by the stamping unit 10 and a stencil sheet of the unused plate storage unit 3. 4 can be wound and stored in a roll. The stored used original mark can be pulled back again and set in the stamping unit 10 and used to print the original mark on the paper. The original stamp printed again on the paper can be used to collate with the original stamp printed earlier (verification of whether the original on which the original stamp has been printed is authentic).

  Thus, in this example, the drawing position of the unused plate storage unit 3, the plate making unit 6, the first conveyance roller 9, the second conveyance roller 16, and the winding position of the stamped plate storage unit 17 are substantially omitted. The stamp portion 10 is set at a lower position between the first and second transport rollers 9 and 16. The unused stencil sheet 4 drawn out from the unused plate storage unit 3 is made by the plate making unit 6 and then conveyed to the first and second conveying rollers 9 and 16 to be stamped on the stamping unit 10 below. The roller 11 is wound around the lower half of the roller 11 and used for printing at the stamp position. After the stamping, the roller 11 is further continuously conveyed and continuously wound into a stamped plate storage unit 17 in a roll shape.

  As shown in FIG. 1, the paper supply unit 18 is attached to the outside of the housing 2 and placed under the original platen 19 on which an original to be imprinted is placed and below the unused plate storage unit 3. And a paper feed roller 20 that supplies a document on the document table 19 to the stamping unit 10. The document sent out by the paper supply unit 18 is sent to the conveyance path 21 set in the housing 2. The conveyance path 21 extends horizontally from the paper feeding unit 18 to the stamping unit 10, passes between the pressing member 12 and the stamp roller 11, curves downward and becomes horizontal again, and further toward the lower side of the paper feeding unit 18. The original can be discharged toward a paper discharge tray 22 which is extended and attached to the outside of the housing 2. The transport path 21 is provided with several paper transport rollers 23 for feeding the original. As shown in FIG. 9, the transported original is in the vicinity of the paper transport roller 23 at the entrance of the stamping unit 10. A detection sensor 24 is provided for detecting the tip of the sheet and for timing of feeding.

  Accordingly, the document fed to the stamping unit 10 by the sheet feeding roller 20 of the sheet feeding unit 18 through the conveyance path 21 is pressed against the stencil sheet 4 of the stamp roller 11 by the pressing member 12 raised at a predetermined timing. The ink supplied from the ink 11 is transferred to the original through the stencil sheet 4 and the original stamp is printed. Then, the document that has received the original stamp is transported along the transport path 21 by the paper transport roller 23 and is discharged to the paper discharge tray 22.

  As shown in FIG. 1, an image reading unit 30 is provided in the conveyance path 21 at a position downstream of the stamping unit 10 and upstream of the paper discharge tray 22 in the conveyance direction. An image data storage unit 31 is connected. The image reading unit 30 reads a document with an original stamp, and the image data is sent to and stored in an image data storage unit 31. The image data stored in the image data storage unit 31 can be displayed on the display unit of the operation unit 5 and checked against the original stamp printed earlier (whether the original on which the original stamp was printed is authentic or not. Used to perform collation). In such an original collation, the used stencil sheet 4 wound up in the stamped plate storage unit 17 is pulled back again and set in the stamping unit 10 to print the original stamp on the paper. When it is necessary to collate with the printed document, but it takes a certain amount of time to pull out the used stencil sheet 4 and print it again. For example, the image data stored in the image data storage unit 31 can be used as described above.

  As shown in FIG. 2, a plate timing sensor 32 is provided along one edge of the stencil sheet 4 between the second transport roller 16 and the stamped plate storage unit 17. FIG. 5 is a top view showing the relationship between the plate making unit 6, the plate timing sensor 32, and the plate on which the original stamp 35 is made. In order to illustrate only the portions necessary for explanation, the stamp unit 10 and The first and second transport rollers 9 and 16 are omitted. The original stamp 35 made by the plate making unit 6 includes, for example, a company name (assumed to be ABCD), the affiliation and name of the stamper, and the date of stamping. Then, the plate making unit 6 makes a timing mark 36 for each original mark 35 outside the stamp face of the stencil sheet 4. Since the timing mark 36 is out of the printing surface, it is not printed on the paper. Even if the original mark 35 is not made, the timing mark 36 is made at regular intervals when the stencil sheet 4 is fed.

  The plate timing sensor 32 is a means for reading the timing mark 36 on the stencil sheet 4. When the original stamp 35 once made is used again or for confirmation, the first and second transport rollers 9, The timing mark 36 is read by the plate timing sensor 32 while the stencil sheet 4 is pulled back by reverse rotation of the stencil sheet 16 and the like, and a desired original mark 35 is located and moved to the stamping unit 10.

  The timing mark 36 in this example is a simple line, and the plate timing sensor 32 can be used by counting the original original mark 35 and the count value in association with each other when the stencil sheet 4 is initially set and stored. By pulling back the stencil sheet 4 until the count value to be counted is reached, the desired original mark 35 is drawn out of the stencil sheet 4 wound around the stamped plate storage unit 17 and set to the stamping position of the stamping unit 10. Can do. Alternatively, numerical information may be added in the form of a barcode or QR code (not shown) instead of a simple line.

  When the stencil sheet 4 is reversed, the thermal head 7 and the platen roller 8 of the plate making unit 6 are set at positions separated from the stencil sheet 4 by a mechanism (not shown) so as not to be stained with ink. .

(2) About the stencil sheet 4 used in the stamping apparatus 1 of the present example With reference to FIGS. 6 to 8, the reason why the stencil sheet 4 is suitable for the stamping apparatus 1 of the present example for automatically stamping the original sheet. explain.
As shown in FIG. 6, the stencil sheet 4 is formed by adhering a heat-melting film 41 with an adhesive 42 to a porous support 40 made of fibers such as Japanese paper or cocoons, regardless of whether it is synthetic or natural. The sheet body. Since this stencil paper 4 is an industrial product, it cannot be a completely uniform product, and its production varies. For example, as shown in FIG. 7 which is an enlarged cross-sectional view of the stencil sheet 4, if there are voids 43 in the fibers of the porous support 40, the film 41 at that portion becomes a slightly depressed concave portion (A portion), and thermal is made during plate making. The heat of the head 7 is difficult to be transmitted, and as shown in FIG. In particular, since the product form of the stencil sheet is a roll, the gap is crushed by the pressure of the stencil sheet sandwiched between the upper and lower sides. Further, as shown in FIG. 7, when the amount of the adhesive 42 that sticks the fibers of the porous support 40 and the film 42 is locally large, the thermal head 7 becomes a film in the portion (B portion). Even if a hole is formed in 41, since it is held and restrained by the porous support 40 by an adhesive, the hole is difficult to spread greatly, and as shown in FIG. Cheap.

  The non-uniformity generated in the perforation in the stencil sheet 4 is unique to each stencil sheet 4 and is irregularly generated. Thus, the pattern generated in the printed image is not in the stencil sheet 4. A unique pattern will be exhibited. Therefore, when the original stamp 35 is made on the stencil sheet 4, an irregular pattern of the porous support 40 appears as a unique pattern particularly in a solid portion, and therefore the stamped state is always mechanized by mechanization as in this embodiment. With the stamping device 1 that can be made constant, it is easier to authenticate the original mark 35 and it is difficult to forge.

(3) About the effect | action of the stamping apparatus 1 of this example With reference to FIG.1 and FIG.9, the effect | action of the stamping apparatus 1 of this example is demonstrated.
As shown in FIG. 9A, a document 45 to be imprinted with the original mark 35 (see “document before printing” in FIG. 1) is sent to the transport path 21 by the paper feed roller 20 of the paper feed unit 18 and the paper The feed roller 23 feeds the stamp roller 11 and the pressing member 12. The pressing member 12 is positioned at the lower limit when the document is fed. The feed amount is detected by the detection sensor 24 based on the position information of the position of the document 45 to be stamped in the paper (the margin position at the top of the document 45 in FIG. 1 “document before printing”). Then, it can be set by controlling the operation time of the sheet conveying roller 23.

  As shown in FIG. 9A, when the first and second transport rollers 9 and 16 send out the stencil sheet 4 from the unused plate storage unit 3, the plate making unit 6 acquires image data acquired from the outside of the apparatus 1. Accordingly, the plate making unit 6 is driven to make the original mark 35 and the timing mark 36 on the stencil sheet 4. Further, the stencil sheet 4 is sent in a state where the pressing member 12 is lowered, and the image of the original mark 35 is sent to the position where it is wound around the stamp roller 11 and set to the stamping position. The pressing member 12 is positioned at the lower limit when the document 45 is fed, but as shown in FIG. 9B, the pressing member 12 is raised at the time of stamping and presses the printing position (upper margin position) of the document 45 against the stamp roller 11. The original mark 35 is printed on the original.

  As shown in FIG. 1, the original document with the original mark 35 is sent to the conveyance path 21 by the paper conveyance roller 23, read by the image reading unit 30, and image data is stored in the image data storage unit 31 ( See FIG. 1 “Image of Stored Data”). The image data stored in the image data storage unit 31 is an image in which an original mark 35 is formed on the entire original image as shown in FIG. 1 and can be displayed on the display unit of the operation unit 5. It can be used for simple collation with the original stamp 35 printed earlier (verification of whether or not the original printed with the original stamp 35 is authentic). The document 45 on which the original mark 35 is printed is discharged onto the sheet discharge tray 22 (see “document after stamping” in FIG. 1).

  After the stamping, the stencil sheet 4 on which the used original mark 35 is formed is sequentially fed and continuously wound into a roll shape in the stamped plate storage unit 17 and stored (see FIG. 1 “Stored Plate”). Image ").

  In this example, the used plate of the original stamp 35 wound up in the stamped plate storage unit 17 can be rewound later and used for printing again. That is, the plate timing sensor 32 continuously counts the timing mark 36 from the time when the stencil sheet 4 is initially set, and stores each original mark 35 formed and each count value in association with each other. Accordingly, the stencil sheet wound around the stamped plate storage unit 17 is pulled back by the first and second transport rollers 9 and 16 in the reverse direction until the stencil timing sensor 32 counts the corresponding count value. The desired original mark 35 can be pulled out of 4 and set at a desired position.

  Therefore, when it is necessary to use the original stamp 35 once made for verification, for example, when it is necessary to use it again, the timing marks 36 are drawn while the first and second transport rollers 9 and 16 are reversed and the stencil sheet 4 is pulled back. Can be read by the plate timing sensor 32, the desired original mark 35 can be found from the count value, and can be moved and set in the stamping unit 10.

  As described above, according to the stamping apparatus 1 of the present example, the original stamp 35 is constituted by the stencil sheet 4 having uniqueness for each plate, and the continuous strip-shaped stencil sheet 4 drawn from an unused roll is used. Making a plate and then winding it up on a used roll continuously after printing, and further making it possible to automatically control the plate making and stamping operations, so compared to conventional hand-stamped stamps, etc. The stamping state on the original is always constant, the printing state is constant, and a high effect can be obtained as an original printing apparatus that reliably utilizes the uniqueness of the stencil sheet 4.

  Further, as described above, the continuous belt-like stencil sheet 4 is continuous from an unused roll to a used roll, and the stencil sheet 4 is made with the original mark 35 together with the timing mark 36 to form each original mark 35. Since the position is managed, it is possible to draw out and specify a desired used original at any time by counting the timing mark 36, etc., and use it for reprinting.
