Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a form having variable information, and more particularly, to a form having variable information composed of characters and numbers obtained by shaving a base material surface by laser irradiation and forming the variable information. About the method.

[0002]

2. Description of the Related Art Conventionally, addresses, names, telephone numbers, IDs
The form on which variable information such as the number and the amount of money is described includes, for example, various notices, certificates, and DMs addressed to individuals. The variable information described in these is usually applied by means such as an ink jet printer or a laser printer.

[0003]

The variable information printed with ink or toner as described above is sometimes falsified or forged by a malicious third party or the like. For example, this is performed by scraping a film of ink or toner constituting the original information, newly adding falsification information with the same color ink, or forging a duplicate using a high-performance color copier.

[0004] In view of the above problems, it is an object of the present invention to provide a form having variable information which makes it difficult to falsify by falsification or copying, and to provide a forming method capable of easily and efficiently applying the variable information. .

[0005]

In recent years, the development of laser technology has been remarkable. In particular, the technology of freely deflecting laser light by employing a plotter mechanism (moving device in the X and Y directions), a polygon mirror, a variable mask, and the like has been developed. It is frequently used in the field of parts manufacturing, especially for engraving on metal surfaces, and its use has been rapidly expanding recently. Therefore, the present inventors have paid attention to this laser technology, and in order to achieve the above object, selectively scrape the base material surface of the form by laser irradiation and apply variable information, thereby making it difficult to falsify or forge. The present invention has been found that it is possible to provide a form to be formed and a method for forming variable information easily and efficiently.

That is, a form having variable information according to the present invention has a variable information description portion at a predetermined portion of the base material surface, and selectively cuts off the base material surface by laser irradiation on the variable information description portion.
It is characterized in that variable information composed of characters, numerals, etc. formed in advance is given.

Further, the method of forming variable information according to the present invention comprises:
A variable information description portion applied to a predetermined portion of the base material surface is irradiated with a laser beam controlled based on data input in advance, and the base material surface is selectively scraped off by the laser irradiation, so that characters and characters can be written. It is characterized by forming variable information including numbers and the like.

[0008] The variable information is formed by changing the pattern of the variable information on the basis of the input pattern data of the variable information to each form input to the laser irradiation apparatus, and sequentially executing the unit forms supplied in a continuous state. Will be In the present invention, the variable information of the holes may be formed by completely scraping the base material of the laser irradiation unit, but preferably, the variable information is left in a state in which the base material of a predetermined thickness is left, that is, in a half-cut manner. Should be formed. In the conventional method for forming an image in a half-cut mode, since an image is formed at a paper making stage or an image is formed by stamping with a mold roll, variable information cannot be entered.

The variable information in the half-cut mode is difficult to visually recognize at a glance, but is visible, and is particularly convenient for passwords and ID numbers that are not desired to be seen by humans. Furthermore, unlike ink and toner films, once applied, the original information cannot be erased, making falsification difficult, and since there is no hue contrast between the information and the substrate surface, forgery of duplicates by color copying Becomes impossible.

[0010]

Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a perspective view of a form having variable information according to the present invention.
FIG. 3 is a sectional view taken along the line XX of FIG. 1, FIG. 3 is a schematic explanatory view of a method of forming variable information in the present invention, and FIG. 4 is a block diagram showing a method of controlling a variable information forming process.

First, as shown in FIG. 1, a form 1 having variable information of the present invention constituted as a "membership certificate" is provided with general information 5 such as a title, a company name, and an explanatory note on a surface of a base material 2. And has a variable information description section 3 in a predetermined section,
The variable information writing unit 3 stores variable information 4 by laser irradiation.
The password and membership number are printed. Further, on the surface of the base material 2, variable information 4 'for normal printing by an ink jet printer, such as an address and a name, is provided in another variable information description section 3'.

As shown in FIG. 2, the variable information 4 is formed by instantaneously burning or sublimating the substrate portion irradiated with the laser and shaving it off, thereby forming half-cut letters and numbers. The base material 1 used for the “membership certificate” in this embodiment is a high-quality paper that is frequently used in forms and the like.
The present invention is not limited to this, and materials such as synthetic paper and synthetic film that can be burned, sublimated, or melted by laser irradiation and that can partially remove the base material can be applied.

Next, an embodiment of a variable information forming method according to the present invention will be described with reference to FIG. A continuous form W provided with a large number of feed holes H in the marginal portion is formed by connecting a large number of unit forms S via a folding / cutting sewing machine line. General information necessary for the "membership certificate" is printed in advance.

The feed hole H is engaged with a tractor pin of the tractor device T, and the continuous form W is transferred in a predetermined direction by driving the tractor device T. A variable information forming device is disposed on the transfer path of the continuous form W. The variable information forming device includes a carbon dioxide laser light oscillator L having a built-in variable mask, and a variable information forming device that changes the traveling direction of the laser light emitted from the laser light oscillator L and changes the direction. In order to form information, two pairs of polarizing mirrors M, M which are incorporated in a plotter mechanism (not shown) movable in the width direction and the transport direction of the continuous form W and are rotatably configured.
And so on.

As shown in the block diagram of FIG. 4, an encoder E for detecting the feed amount of the continuous form W is connected to the tractor device T. The encoder E converts the rotation amount of the tractor device T into a pulse signal. Feed amount is detected. When the converted pulse signal is sent to the control unit C, the control unit C sends the pattern data of the input variable information at the timing corresponding to the feed amount, that is, at the time when the variable information writing unit 3 reaches the laser irradiation position. , A control signal is issued to the laser light oscillator L and the drive unit of the polarizing mirrors M, M to control them. Further, an input device K such as a keyboard and a display device B such as a CRT are connected to the control unit C to input desired variable information pattern data and check operation conditions.

Further, in the apparatus of the present embodiment, an optical detection sensor D for detecting the timing at which the variable information description section 3 of each unit form S reaches the laser irradiation position is also arranged on the transfer path of the continuous form W. The detection signal is also sent to the control unit C. Note that a detection mark (not shown) is provided at the marginal portion of each unit form S for detecting the laser irradiation position.

In the embodiment shown in FIG. 1, as an example of a condition for partially removing the base material 2 while keeping a predetermined thickness, a high-quality paper having a basis weight of 64 g moving at a transfer speed of 60 m / min is used. The half-cut mode was achieved by irradiating the substrate with carbon dioxide laser light with an output of 15 to 30 W. In addition, adjustment of the depth of the cut portion according to the type and thickness of the base material is performed because the energy received by the unit of the base material is inversely proportional to the transfer speed and proportional to the output. This is done by adjustment.

In the embodiment of the variable information forming method shown in FIG. 3, a suction drum V for stabilizing the focus is provided at the laser irradiation position so that the focal length of the laser light does not shift during the irradiation of the laser light. Furthermore, although a proper tension is applied between the tractor device T and the two pairs of guide rolls G, G so as not to loosen the form, other than this method, for example, the form roll may be wound around a large-diameter roll at a predetermined wrap angle. A laser irradiation section may be set in this wrap portion.

Further, in this embodiment, in order to form arbitrary variable information, a laser light oscillator having a built-in variable mask and a laser irradiator having a rotatable polarizing mirror incorporated in a plotter mechanism are provided. Although used, the present invention is not limited to this, and various types of laser irradiation devices used for laser image formation can be used.

[0020]

As described above, according to the form having the variable information according to the present invention, the base material is selectively scraped off by laser irradiation to apply the variable information. If this is done, the original information cannot be erased, so that falsification becomes difficult, and since there is no hue contrast between the information and the substrate surface, forgery by copying becomes impossible. Furthermore, since variable information is applied by laser irradiation controlled based on data input in advance, it is possible to easily and efficiently change the pattern of the variable information.
