[0003]
[Problems to be solved by the invention]
However, information copied to the paper under pressure-sensitive copying is sometimes falsified or forged by a malicious third party. These may be done, for example, by scraping the copy information and newly adding tampering information on another pressure-sensitive copying paper, or forging the pressure-sensitive copying paper itself with a high-performance color copier. is there.
[0004]
Accordingly, in view of such problems, the present invention provides a pressure-sensitive copying upper paper that prevents falsification of information copied on the pressure-sensitive copying paper and forgery by a copying machine, and a pressure-sensitive copying form having the same. Objective.
[0005]
[Means for Solving the Problems]
In recent years, the development of laser technology has been remarkable, and in particular, the technology for freely moving and deflecting laser light using a variable mask, plotter mechanism (XY axis direction movement mechanism), polygon mirror, etc. Recently, the technology has developed rapidly, and micro characters can be marked.
[0006]
Therefore, the present inventor pays attention to this laser technology, and in order to achieve the above object, the color former microcapsule layer on the back surface of the base sheet is selectively scraped off by laser irradiation to give a non-copyable portion having a predetermined shape. It has been found that a pressure-sensitive copying form that makes it difficult to falsify or counterfeit can be provided by creating a new pressure-sensitive copying upper paper and using it, and the present invention has been conceived.
[0007]
That is, the pressure-sensitive copying upper paper of the present invention has a non-copyable portion having a predetermined shape formed by selectively scraping off the color former microcapsules by laser irradiation on the color former microcapsule layer provided on the back surface of the base sheet. It is characterized by being made.
[0008]
Further, a preferable pressure-sensitive copying upper sheet of the present invention is characterized in that the shape of the non-copyable portion is a fine pattern such as a micro character, a line, or a repeated pattern.
[0009]
Further, the pressure-sensitive copying form of the present invention comprises a high-order form comprising the above pressure-sensitive copying upper paper having an information entry part in a predetermined part of the surface corresponding to the color former microcapsule layer provided with a non-copyable part of a predetermined shape. And a lower form made of a sheet under pressure-sensitive copying having an information copying section corresponding to the information entry section on the surface thereof, in a separable manner.
[0010]
Formation of a non-copyable portion of a predetermined shape on the color former microcapsule layer of pressure-sensitive copying paper is performed by irradiating the color former microcapsule layer with laser light based on the predetermined shape data inputted to the laser irradiation device. Is done. The color former microcapsules selectively irradiated with laser are burned or sublimated and scraped off instantaneously, thereby giving a non-copyable portion of a predetermined shape.
[0011]
The non-copyable portion having a predetermined shape is preferably a fine one that does not make the copy information difficult to read, although it depends on the size of the copy entry field, that is, the size of the entered characters. Therefore, a fine pattern such as a micro character, a line, and a repeating pattern is suitable. When a non-copyable portion having such a shape is formed, a blank image composed of a fine pattern or the like is incorporated into the copy information, so that it is difficult to tamper with and difficult to appear with a copy machine, and forgery is also difficult.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail based on preferred embodiments. Here, FIG. 1 is a plan view of the back side of the pressure-sensitive copying upper sheet of the present invention and a partially enlarged view of the accompanying sheet, FIG. 2 is a schematic sectional explanatory view of the partially enlarged view of FIG. 1, and FIG. 4 is an exploded explanatory view of a copy form, FIG. 4 is an enlarged explanatory view of copy information applied to a sheet under pressure-sensitive copying, and FIG. 5 is an explanatory view of a method for forming a non-copyable portion of a predetermined shape on a color former microcapsule layer.
[0013]
As shown in FIG. 1, the basic structure of the pressure-sensitive copying upper sheet 1 of the present invention is that the color developing agent microcapsule layer C is applied to the back surface of the base sheet F, and the color development is performed as shown in the accompanying partial enlarged view. The agent microcapsule layer C is provided with a non-copyable portion D having a predetermined shape formed by selectively removing the color former microcapsules by laser irradiation. This non-copyable portion D is composed of, for example, a fine pattern such as a partially enlarged view (b): micro characters and (b): filaments (straight line, wavy line, broken line, dotted line, etc.), as shown in FIG. Since the color former microcapsules are removed, it does not have a copying function.
[0014]
Next, examples of the pressure-sensitive copying form of the present invention will be given.
As shown in FIG. 3, the pressure-sensitive copying form 10 of the present embodiment includes a high-order form 11 comprising the pressure-sensitive copying upper sheet 1 of the present invention as a “receipt” and a pressure-sensitive copying lower sheet 2 as a “receipt (deduction)”. The lower form 12 is formed by being separably bound at the end by a sewing line and an adhesive. General information 3 such as a title, company name, and explanatory text is applied to a predetermined portion of the surface of the base sheet F of the pressure-sensitive copying upper paper 1 and the pressure-sensitive copying lower paper 2, and the pressure-sensitive copying upper paper 1 An information entry unit 4 such as a customer name column, a receipt date column, and an amount column is provided, and an information copy unit 5 corresponding to the information entry unit 5 is provided on the pressure-sensitive copy lower sheet 2, and accordingly, a higher form 11 and a lower form 12 are provided. Is configured.
[0015]
Therefore, when predetermined information is entered in the information entry section 4 of the upper form 11, the copy information 6 applied to the information copy section 5 of the lower form 12 is colored on the pressure-sensitive copying upper sheet 1 as shown in FIG. A fine pattern white image d (indicated by a dotted line in the figure) corresponding to the non-copyable portion D of the predetermined shape of the agent microcapsule layer C is incorporated.
[0016]
The pressure-sensitive copying upper paper in the present invention is not limited to the color former microcapsule ink, even if the color former microcapsule aqueous coating is applied to the entire back surface of the base sheet and the color former microcapsule layer is applied. A color former microcapsule layer may be spot-coated on a predetermined area containing the back side of the information entry part (that is, the contact part of the information copying part of the paper under pressure-sensitive copying). Further, the non-copyable portion having a predetermined shape may be spot-applied on the entire surface of the color former microcapsule layer or only on a desired portion. Further, a developer layer may be formed on the surface of the base sheet, and it may be configured as a pressure-sensitive copying paper.
[0017]
Hereinafter, an example of a method for forming a non-copyable portion having a predetermined shape on the color former microcapsule layer will be described with reference to FIG. The non-copyable portion having a predetermined shape is formed on the color former microcapsule layer C with respect to a conventional pressure-sensitive copying upper paper web W (hereinafter referred to as the web W) in which a number of feed holes H are provided in the marginal portion. Done. The web W is formed by spotting a color former microcapsule layer C on the back surface of a long base sheet F with a color former microcapsule ink.
[0018]
The feed hole H is engaged with a tractor pin of the tractor device T, and the web W is transferred in a predetermined direction by driving the tractor device T. The transfer path of the web W can be moved in the width direction and the transfer direction of the web W in order to form the variable information by changing the traveling direction of the laser light emitted from the carbon dioxide laser oscillator L having a variable mask and the laser beam emitted from the laser beam. A pair of polarizing mirrors M, M, etc., which are incorporated in a simple plotter mechanism (not shown) and are configured to be rotatable, are provided.
[0019]
The tractor device T is connected to an encoder for detecting the feed amount of the web W, and the feed amount is detected by converting the rotation amount of the tractor device T into a pulse signal. When the converted pulse signal is sent to the control unit, the control unit sends the color former micro at the timing corresponding to the feed amount, that is, at the laser irradiation position (the suction drum V for focus stabilization is installed at this position). When the capsule layer C arrives, based on the input shape data, a control signal is sent to the laser light oscillator L and the driving units of the polarizing mirrors M and M to control laser oscillation and driving.
[0020]
In this manner, the color former microcapsules selectively irradiated with the laser are scraped off instantaneously, whereby the color former microcapsule layer C is provided with a non-copyable portion D having a predetermined shape. Further, the shape of the non-copyable portion D is changed by another control signal based on another shape data input to the control unit.
[0021]
In the example of forming the non-copyable portion shown in FIG. 5, the non-copyable portion having a predetermined shape is formed on the color former microcapsule layer, and laser light is irradiated through a variable mask and incorporated into the plotter mechanism. Although the laser irradiation apparatus including the polarizing mirror configured to be rotatable is used, the present invention is not limited to this, and various types of laser irradiation apparatuses used for laser image formation can be used.
[0022]
In addition, a suction drum V for stabilizing the focus is installed at the laser irradiation position so that the focal length of the laser beam does not blur when the laser beam is irradiated, and a tension is applied between the tractor device T and the two pairs of guide rolls R and R. However, other than this method, for example, a large diameter roll may be wound at a predetermined wrap angle, and a laser irradiation unit may be set at the wrap portion.
[0023]
【The invention's effect】
As described above, according to the pressure-sensitive copying upper paper of the present invention and the pressure-sensitive copying form having the same, the color former microcapsules are selectively scraped off by laser irradiation, and a predetermined shape is copied to the color former microcapsule layer. By providing the impossible portion, a white image consisting of a fine pattern or the like is incorporated into the copy information, and it is difficult to tamper with, and since this is difficult to be displayed by a copy machine, counterfeiting is also difficult.
