DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for forming an uneven pattern plate, and more particularly to an apparatus for forming an uneven pattern plate which can be easily formed by a person other than a plate making expert or a specialist.

[0002]

2. Description of the Related Art In some cases, a plate, a chestband, or the like, which is used for an entrance of a private room, a tenant guide of a building, or the like, is formed with a stamped concavo-convex pattern on the surface like a stamp. Such plates and the like are often created by specialists and specialized traders, especially those with uneven characters on the surface, whether by hand or using a machine, select one side or both sides of the plate-shaped body Often created by engraving. Also, a mold having irregularities opposite to the irregularities of the target pattern is formed of, for example, resin, and then a fluid such as rubber is poured into the mold and solidified to form an irregular surface member. It is also made by attaching it to the body.

[0003] However, the number of plates that corporations and individuals desire to own is large. In such a case, when an expert or a specialist is requested to create the uneven pattern plate, there may be a problem in terms of money and a period until the creation.

[0004] Although different from the concavo-convex pattern plate to which the present invention is applied, there is a similar problem with a seal such as a rubber stamp. A seal making apparatus (strictly speaking, a kit is suitable) that can easily make a desired seal by a person other than a seal making expert or a specialized trader is already on the market. Since the embossed pattern plate and the stamp have a common feature of having an embossed pattern on a certain surface, the technology of the stamp making apparatus can be applied to the embossed pattern plate forming apparatus. Therefore, a conventional stamp making apparatus will be examined. .

[0005] Although a conventional stamp making apparatus is not shown, it is provided with an ultraviolet-sensitive film, an ultraviolet irradiation device, a flat UV-curable resin member (sign face member), and a stock. To create a seal. The ultraviolet irradiation device includes a housing having a built-in ultraviolet fluorescent lamp, a timer for setting the lighting time of the ultraviolet fluorescent lamp by a user, and a transparent mounting provided on the upper surface of the housing for transmitting ultraviolet light. It is composed of a plate and a lid that can be opened and closed to prevent the ultraviolet light transmitted through the transparent mounting plate from leaking to the outside. Further, the ultraviolet curable resin member is composed of a base layer insensitive to ultraviolet light and an ultraviolet curable resin layer, and the base layer is thinner than the ultraviolet curable resin layer.

When a stamp is to be created by a conventional stamp making apparatus, first, the stamp or stamp is printed on an ultraviolet ray transmissive paper such as a tracing paper to transfer the characters or designs ( The original image is created by writing the pattern. After that, the original image and the UV-sensitive film are superimposed on the transparent mounting plate of the UV irradiation device, and the lid is closed, and the irradiation time according to the paper quality of the original image is set by a timer. Then, ultraviolet rays from an ultraviolet fluorescent lamp are irradiated for a predetermined time. The film thus exposed is washed with a predetermined liquid (water in a commercially available apparatus) to obtain a negative film in which the concavo-convex pattern has been inverted from the negative to the positive. That is, a negative film is obtained in which the concavo-convex pattern portion is transparent to ultraviolet rays and the other portions are brown (ultraviolet ray cut color).

Next, after placing the negative film and the ultraviolet-curable resin member on the transparent mounting plate of the ultraviolet irradiation device, the cover is closed, and the ultraviolet light from the ultraviolet fluorescent lamp is closed for a predetermined time. Only irradiate. By this irradiation, an ultraviolet ray irradiated portion (corresponding to the concavo-convex pattern) of the ultraviolet ray cured resin member is cured, and other portions are not cured. After such a curing treatment, the UV-curable resin member is washed with a predetermined liquid (water in a commercially available apparatus) to remove the uncured portion, so that the UV-cured resin layer of the concavo-convex pattern portion has the other portions. An engraved surface member protruding from the base layer is completed. Ultraviolet rays are further applied to the stamp face member completed in this way to fix the stamp face.

The stamp is completed by attaching the stamp face member to a stock.

[0009]

As described above, since the uneven pattern plate and the seal have a common feature of having an uneven pattern on a certain surface, the technology of the seal making apparatus is also applied to the uneven pattern plate forming apparatus. It is possible. Conversely, the problem in the conventional stamp making device is also a problem in a case where the technology of the stamp making device is applied to the uneven pattern plate forming device.

According to the conventional stamp making apparatus, including the work of creating the original image, the stamp creator has to perform a very large number of works, resulting in poor workability and a long preparation time. Have a problem. Despite the presence of the irregular pattern in the original image itself, this information cannot be used directly to create a stamping surface member, that is, it is necessary to create a negative film as an intermediate member. This is a major cause of the above problem.

Unless the original image is created by hand, the original image is created in a predetermined font, so that a word processor or the like is used. Therefore, it takes much time and effort to create an original image because it is necessary to make a copy on an ultraviolet ray transmissive paper by using the above method.

Further, it is necessary to set an ultraviolet irradiation time using a timer or the like in accordance with the thickness of the ultraviolet light transmitting paper, the density of the document, and the like, which requires some skill.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and provides an uneven pattern plate producing apparatus which can produce a desired irregular pattern plate easily and in a short time even by a person other than a plate producing expert. The purpose is to:

First, the electrical components of this embodiment will be described with reference to FIG.

This electrical component is mainly for controlling the optical component for transferring the concave and convex information by taking in the concave and convex pattern information, and corresponds to a kind of information processing apparatus. Like the general electronic information processing apparatus, the input unit 10, the control unit 20, and the output unit 30
It is composed of The control unit 20 executes processing according to the information from the input unit 10 and the processing stage at that time, and controls the optical component for transferring unevenness information via the output unit 30 according to the processing result and the like. Things.

The input unit 10 includes a key input unit 11 provided with a press key, a dial key, and the like, an image reading unit 12, and an uneven pattern plate type detection sensor
It is composed of

The key input unit 11 generates character code data and various control data to be given to the control unit 20.

For example, the uneven pattern plate main body and its mounting jig are provided with physical identification elements such as holes that define the uneven pattern plate type, and the uneven pattern plate type detection sensor 13 reads this physical identification element. To output the uneven pattern plate type information. The uneven pattern plate type detection sensor 13 may be omitted.

The output unit 30 is provided with an ultraviolet light source 5 to be described later.
0, a driving circuit 32 of a liquid crystal panel unit 51 for transferring an uneven pattern, which will be described later, and a driving circuit 33 of a display liquid crystal device 34.
2, 33 drive corresponding components under the control of the control unit 20. The display liquid crystal device 34 corresponds to a display device in the information processing device, and displays a guidance message for the creator of the concavo-convex pattern plate, the concavo-convex pattern information input by the creator of the concavo-convex pattern plate, and the like. Is what you do.

The ultraviolet irradiation light source 50 and the liquid crystal panel portion 51 for transferring the uneven pattern will be described later, including the drive control thereof.

The control unit 20 is constituted by, for example, a microcomputer, and includes a CPU 21, a ROM 22,
RAM 23, character generator ROM (CG-R
OM) 24, an input interface 25, and an output interface 26 are connected via a system bus 27.

The ROM 22 stores various processing programs (see FIG. 4 and FIG. 5) for creating a concavo-convex pattern plate to be executed by the CPU 21 and a table for converting key-input code data into a character code corresponding to the code. For example, in the case of Japanese, fixed data such as kana-kanji conversion dictionary data for converting a “kana” code to a “kanji” code is stored.

The RAM 23 is used as a working memory by the CPU 21, and stores fixed data relating to user input.

The CG-ROM 24 stores dot patterns of characters and symbols prepared by the concavo-convex pattern plate making machine, and corresponds to code data for specifying characters and symbols. This is to output a dot pattern. Note that separate CG-ROMs may be provided for display and for transferring the uneven pattern.

The input interface 25 performs an interface between the input unit 10 and the control unit 20.
The output interface 26 includes an output unit 30 and a control unit 20.
Interface between the two.

The CPU 21 uses a processing program in the ROM 22 determined according to an input signal from the input unit 10 and a processing stage at that time, while using the RAM 23 as a working area.
The processing is performed by using the fixed data stored in the storage device 3 as appropriate, and the processing status, the processing result, and the like are displayed on the display liquid crystal device 34, and the ultraviolet irradiation light source 50 and the uneven pattern transfer liquid crystal panel unit 51 are operated. Drive it to create a textured plate.

Next, the configuration of the optical component for transferring an uneven pattern and the main body of the uneven pattern plate will be described with reference to FIG.

The concave / convex pattern plate main body 40 is composed of a base plate (not necessarily wooden) 41 and a flat engraved surface member 42 attached to one surface of the base plate 41. The engraving surface member 42 includes a base layer 42 that is not reactive to ultraviolet rays.
a and the ultraviolet curable resin layer 42b, and the ultraviolet curable resin layer 42b is exposed to the outside.

The concave / convex pattern plate main body 40 is detachably attached to the concave / convex pattern plate making machine 45 by an attaching mechanism (not shown). For example, the rectangular uneven plate body 40 is attached such that one corner of the rectangle conforms to a rectangular coordinate system in which one corner coincides with the reference point, and the circular or oval (elliptical) uneven plate body 40 is attached, for example. By being loaded via a jig, it is attached to the uneven pattern plate maker 45 in the same manner as the rectangular uneven pattern plate body 40. At the time of attaching the uneven pattern plate, it is preferable to prevent ultraviolet rays from leaking to the outside of the uneven pattern plate creating machine 45.

The optical component for transferring unevenness information includes an ultraviolet light source 50, a liquid crystal panel portion 51 for transferring unevenness that can control the transmission of ultraviolet light, and an objective lens (often realized by a combination lens) 52. Are arranged in this order, and the above-described ultraviolet curable resin layer 42b is a target to be irradiated with ultraviolet rays. In addition, a diffusion plate may be provided between the light source 50 and the uneven pattern plate main body 40 in order to make the light beams uniform.

The ultraviolet light source (for example, fluorescent tube) 50 is
The ultraviolet light is emitted only during the period when the ON command from the light source drive circuit 31 is given. The injection time is selected as a time at which the ultraviolet curable resin layer 42b sufficiently cures. The ultraviolet irradiation light source 50 may be turned on / off by an on / off switch or the like. That is, the on / off of the ultraviolet irradiation light source 50 is set to C
The PU 21 may not be controlled.

The two-dimensionally arranged cells of the uneven pattern transfer liquid crystal panel 51 are controlled by the controller 20 under the control of the controller 20.
The on / off state is set by the above-described liquid crystal panel drive circuit 32. The cell set to the on state transmits ultraviolet light from the light source 50, and the cell set to the off state transmits the ultraviolet light from the light source 50. To prevent. Here, the on / off setting for each cell is performed so as to be similar to the concavo-convex pattern as clarified in the operation description to be described later, whereby the ultraviolet image transmitted through the concavo-convex pattern transfer liquid crystal panel unit 51 becomes a concavo-convex pattern image. It has become.

In general, a liquid crystal panel is used for a display device and transmits visible light. However, there is a liquid crystal panel having an ultraviolet region as a transmission region. Can be applied to the above-mentioned concave / convex pattern transfer liquid crystal panel section 51 by using as it is or by providing an ultraviolet transmission filter.

The objective lens 52 is for forming an ultraviolet image having an uneven pattern image on the ultraviolet curing resin layer 42b. It is preferable that the focal plane of the objective lens 52 be slightly different from the surface of the ultraviolet curable resin layer 42b. When the focal plane and the surface of the ultraviolet curable resin layer 42b are completely coincident with each other, the contour of the concave and convex pattern becomes jagged due to the arrangement of the cells of the liquid crystal panel unit 51 for transferring the concave and convex pattern. If the surface is slightly displaced from the surface of the ultraviolet curable resin layer 42b, the light beams from the cells slightly overlap each other, and the contour of the uneven pattern can be prevented from being jagged.

The ultraviolet curable resin layer 42b can be removed by a predetermined liquid (for example, water: gas) except for the cured portion.

The concavo-convex pattern plate forming apparatus having the electrical component shown in FIG. 2 and the optical component for transferring concavo-convex information shown in FIG. 1 has, for example, the appearance shown in FIG. In the external appearance example shown in FIG. 3, the key input unit 11, the display liquid crystal device 34, and the mounting structure 55 of the uneven pattern plate body 40 are arranged at appropriate positions on the operation panel surface, and the image reading unit 12 It is connected to the main body 56 of the uneven pattern plate making machine via the same.

Next, with reference to FIG. 4, an example of a process of capturing uneven pattern information performed by the CPU 21 as a center will be described.

For example, when the key input unit 11 instructs the process of capturing the concavo-convex pattern information, the CPU 21
4 is started, and first, the type of the uneven pattern plate is displayed on the display liquid crystal device 34, and the creator of the uneven pattern plate is input from the key input unit 11. Fetches the information of the selected uneven pattern plate type (step 100). Here, the uneven pattern plate type is defined by the outer shape of the marking surface such as rectangle, circle, and oval, and the size such as large, medium, and small. What can be handled is predetermined.

Next, the CPU 21 operates the display liquid crystal device 34.
A message asking whether to input the image of the concavo-convex pattern information or to input the image is displayed, and the information of the input method selected by the creator of the concavo-convex pattern plate is taken from the key input unit 11 to determine the selected input method. (Step 10
1).

Here, when the image input is selected, a message requesting that the original be set in the image reading section 12 and the image reading section 12 be started is displayed on the display liquid crystal device 34, and the image reading section 12 The read image data is captured (step 102). Then, the read image and the outer contour of the engraved surface relating to the designated concavo-convex pattern plate type are superimposed and displayed on the display liquid crystal device 34, and a designation of a portion to be used for the concavo-convex pattern in the read image is obtained. The obtained concave / convex pattern portion is fetched, and only that portion is displayed on the display liquid crystal device 34 as a concave / convex pattern image, and the process of capturing the concave / convex pattern information ends (step 103).

For example, when the creator of the concavo-convex pattern plate operates the cursor key of the key input section 11, the outer contour display of the engraved surface relating to the designated type of the concavo-convex pattern plate is moved in that direction. When the enter key is operated, the portion of the read image surrounded by the outer contour display of the engraving surface at that time is taken in as the one designated as the uneven pattern.

On the other hand, when the CPU 2 recognizes that the key input method has been selected as the input method of the concavo-convex pattern information, the CPU 2
1 displays on the display liquid crystal device 34 a message requesting that the attribute information of the concavo-convex pattern be specified, and captures the attribute information of the specified concavo-convex pattern (step 104). The attributes of the concavo-convex pattern include, for example, whether or not a frame is included, whether the document is written vertically or horizontally, the number of lines, the size of the character (either absolute or relative) or intaglio (corresponds to the inverted display in the display).
Performs character shape conversion (e.g., circularization) using a positive or negative (corresponding to non-reversal display in display), character typeface, whether or not to create the whole as a faint blur, or a circular uneven pattern plate. Whether or not there is the size of the outer shape of the concavo-convex pattern portion and the like are taken in. Some attributes do not allow designation due to restrictions such as the size of the designated concavo-convex pattern plate.
For example, in the case of a small uneven pattern plate, prohibiting a multi-line pattern is performed.

Thereafter, the CPU 21 asks the creator of the uneven pattern plate for the input of the character information by the display by the display liquid crystal device 34, and performs the same processing as the information processing device such as a so-called word processor through the key input unit 11. The input character information is captured (step 105).
Note that the display in this input process is not a display like an uneven pattern image. When the input of the character information is instructed, the CPU 21 converts the input character information in accordance with the specified various attributes, and displays the converted character information on the display liquid crystal device 34 as a concavo-convex pattern image to create a concavo-convex pattern plate. Then, the process of capturing the uneven pattern information is completed (step 106). The display of the input characters and the display of the concavo-convex pattern image of the characters input up to that point may be switched according to the key operation of the user.

The creator of the concave / convex pattern plate may immediately start the transfer process to the engraving surface member 42 upon completion of the input operation of the concave / convex pattern information, or temporarily store it in the RAM 23 (or an external storage device). You can also do so.

For example, in the state in which the uneven pattern image is displayed on the display liquid crystal device 34 (including the case where the stored one is read out and displayed), the creator of the uneven pattern plate may use the key input unit 11. Can be used to instruct transfer to the marking surface member 42. At this time, CPU 2
1 starts a transfer processing program to the engraving surface member 42 shown in FIG.

First, the CPU 21 takes in the information from the uneven pattern plate type detecting sensor 13 and confirms that the uneven pattern plate body 40 is mounted on the uneven pattern plate creating machine 45, and that the mounted uneven pattern plate is mounted. It is confirmed that the type of the main body 40 is specified (step 200).

Here, when the result of not mounting or mounting error is obtained, a message requesting mounting or a message requesting replacement of the mounted uneven pattern plate body 40 is displayed on the display liquid crystal device 34. Error processing (step 201).

On the other hand, if the validity of the mounted concavo-convex pattern plate main body 40 is confirmed, the cell of the concavo-convex pattern transfer liquid crystal panel section 51 is selected according to the concavo-convex pattern in question. Set on / off (step 20)
2). In the case of this embodiment, the cells corresponding to the concavo-convex pattern are set to the ON state, and the cells corresponding to the background are set to the OFF state. Thereafter, the CPU 21 causes the ultraviolet irradiation light source 50 to emit light for a predetermined time (step 203). And
After a lapse of a predetermined time, a message indicating that the irradiation has been completed or that the ultraviolet curable resin layer 42b of the concavo-convex pattern plate body 40 is to be washed with a predetermined liquid (water) is displayed on the display liquid crystal device 34, and a series of messages is displayed. The transfer processing of the uneven pattern is completed (step 204).

The creator of the uneven pattern plate washes the ultraviolet curing resin layer 42b of the uneven pattern plate main body 40 after the transfer process (curing process) with a predetermined liquid, so that portions other than the uneven pattern are removed from the ultraviolet curing resin layer 42b. The concavo-convex pattern forming the concavo-convex pattern is formed by removing the concavo-convex pattern, thereby completing the concavo-convex pattern plate.

It is preferable that after the cleaning with the predetermined liquid, the uneven pattern plate main body 40 is attached to the uneven pattern plate maker 45 again and irradiated with ultraviolet rays to ensure the resin curing. In this case, all the cells of the liquid crystal panel unit 51 for transferring unevenness information are set to the open state.

FIGS. 9 to 11 show examples of the uneven pattern plate formed by this embodiment. FIG. 9 shows an example of a badge and the like.
An engraved surface member 42 having an A & B "pattern formed with irregularities is fixed. FIG. 10 shows an example of a door display board, a company emblem, and the like. The engraving surface member 42 is fixed, and Fig. 11 shows an example of a name plate,
A stamping surface member 42 in which an alphabet pattern is formed with irregularities directly is fixed to 1.

Regardless of the badge shown in FIG. 9, the door display plate shown in FIG. 10, the company emblem, the name plate shown in FIG. 11, etc., in order to enhance the visibility, an ultraviolet curable resin layer is used. 42b, base layer 42a and / or base plate 4
It is preferable to make the color different from one. Further, in the case of a room number plate which is vertically mounted on a door mounting frame or the like toward the corridor side, an uneven pattern may be formed not only on one side but also on both sides.

As described above, according to the above-described embodiment, the operation of creating a negative film is unnecessary, and the information corresponding to the original image can be easily created using the key input unit 11 or the like. A person other than an expert in making a pattern plate can easily and quickly create a desired concavo-convex pattern plate.

FIGS. 3 and 4 show the basic processing flow. However, since the embodiment has an information processing structure, the size of the uneven pattern plate main body (hence, It is also possible to easily change the size of the pattern and the attribute of the uneven pattern. For the same reason, it is possible to obtain various concavo-convex pattern plates having different concavo-convex patterns, although the sizes of the concavo-convex pattern plates are different, by a single process of inputting the concavo-convex pattern information.

Further, in the above embodiment, since the ultraviolet curable resin layer 42b which remains by curing is applied to the portion which becomes the convex portion constituting the concave / convex pattern, each cell of the concave / convex pattern transfer liquid crystal panel portion 51 is turned on / off. At the time of setting, it is not necessary to convert the input concavo-convex pattern information, that is, it is not necessary to perform reverse character processing (mirror character conversion processing), and the load on information processing is small.

It should be noted that the present invention is not limited to the first embodiment. Some of the modified embodiments related to the first embodiment are as follows.

(1) The objective lens 52 may be constituted by a zoom lens, and the function of the objective lens 52 may be used to enlarge or reduce the concavo-convex pattern. In this case, a drive system for moving a part of the zoom lens is required. It should be noted that, in the case of scaling by the optical system, smoothing of the contour line of the concavo-convex pattern can be achieved as compared with the case of scaling by the information processing by the bitmap method. In this case, the processing time can be reduced as compared with the case of performing the above operation, and the magnification can be set freely.

(2) A component for performing a cleaning step of the cured resin layer 42b with a predetermined fluid may also be provided in the concavo-convex pattern plate making machine 45. For example, the uneven pattern plate main body 40 after the hardening process (unevenness information transfer process) is moved, and its tip is immersed in a predetermined liquid stored in the housing container to automatically remove portions other than the hardened portion. You may do it.

(3) The objective lens 52 may be omitted, and the UV curable resin layer 42b of the concave / convex pattern plate body 40 may be brought into direct contact with the surface of the concave / convex pattern transfer liquid crystal panel 51 to cure the concave / convex pattern portion. good.

(4) Only the marking surface member 42 separate from the base plate 41 may be mounted on the concave and convex pattern plate forming machine 45 to perform the curing treatment of the ultraviolet curable resin layer 42b. In this case, it is preferable to provide an adhesive layer, which is usually covered with release paper, on one of the base plate 41 and the engraving surface member 42 to facilitate the adhesion between the base plate 41 and the engraving surface member 42.

(5) As a part of the present invention, a commercially available information processing device may be applied. For example, a word processor, a personal computer, or a tape printer is applied as an information processing configuration other than the unevenness information transfer optical component unit, and ON / OFF information for each cell of the unevenness pattern transfer liquid crystal panel unit 51 is provided via a cable. Or you may.

(6) The display liquid crystal device 34 and the uneven pattern transfer liquid crystal panel 51 may be realized by one liquid crystal device.

For example, as shown in FIG.
As (34), an ultraviolet light source 501 capable of transmitting ultraviolet light and visible light is applied, and an ultraviolet irradiation light source 501 having a parabolic mirror is used.
And a visible light irradiating light source 502 are separately provided, and the liquid crystal device 5 is illuminated by the oscillating mirror 503 with visible light emitted from the visible light irradiating light source 502 when functioning as a display device.
1 may be backed up, and the liquid crystal device 51 may be backlit by the ultraviolet light emitted from the ultraviolet light source 501 at the time of transferring the unevenness information. Alternatively, as shown in FIG. 7, a liquid crystal device 51 (34) that can transmit ultraviolet light and visible light is applied, and an ultraviolet irradiation light source 501 and a visible light irradiation light source 502 are provided with a parabolic mirror 504 in common, When functioning as a display device, a visible light irradiation light source 5
The liquid crystal device 51 is back-lit with visible light emitted from the mirror 02 and reflected by the mirror 505, and the liquid crystal device 51 is back-lit with ultraviolet light emitted from the ultraviolet irradiation light source 501 and reflected by the mirror 505 at the time of transferring unevenness information. May be.

(7) Liquid crystal panel section 51 for transferring an uneven pattern
May have a one-dimensional configuration, and in the sub-scanning direction, the transfer of the concavo-convex pattern may be performed by moving the marking surface member 42 or the concavo-convex pattern transfer liquid crystal panel unit 51.

FIG. 8 shows the latter example. The light source unit 510 has a built-in ultraviolet irradiation light source having a parabolic mirror (not shown), and a one-dimensional liquid crystal panel illuminated by the ultraviolet irradiation light source. In FIG. 8, black hatched portions represent cells that do not transmit ultraviolet light. The light source unit 510 is fixed to a belt 512, and the belt 512 is stretched over two rollers 513 and 514 fixed at a predetermined interval by a guide frame 515. One of the rollers 513 and 514 is rotationally driven by a driving unit (not shown) and is fixed to the belt 512 by the light source unit 5.
10 is moved in the horizontal direction of the drawing, that is, in the sub-scanning direction.

(8) As the cured resin layer 42b, one that is cured by physical factors other than ultraviolet rays can be used. For example, a visible light curable resin or a thermosetting resin can be used. When a visible light curable resin is used, the uneven pattern plate body 40 is distributed in a state where the visible light curable resin layer is covered with a visible light cut release paper, and the release paper is peeled off only at the time of the unevenness information transfer processing. Is preferable. When a thermosetting resin is used, instead of the liquid crystal panel unit 51 for transferring a concavo-convex pattern, a panel unit in which heat generation control elements employed in a thermal transfer printer or the like are arranged one-dimensionally or two-dimensionally is applied. It is necessary to bring the cured resin layer into direct contact with the panel portion as in the modified embodiment (3).

(9) As the resin constituting the marking surface, a resin which can be removed by a predetermined liquid at a portion to which a predetermined physical stimulus is applied, such as a resin which collapses by irradiation of ultraviolet rays, may be applied.

(10) As a method of inputting the concavo-convex pattern, only image reading may be made possible, or only key input may be made possible. For example, in an uneven pattern plate forming apparatus that performs only image reading, the image information read by the image reading unit may be directly provided to the uneven pattern transfer liquid crystal panel unit. In this case, the CPU itself may be omitted,
Alternatively, input control and transfer control by the CPU may be omitted.

Next, an apparatus for forming a concavo-convex pattern according to a second embodiment of the present invention will be described in detail with reference to FIGS.

This embodiment is different from the first embodiment in that the pattern of the concavo-convex pattern plate is formed on the marking surface member 42 by using a scanning light beam.

The uneven pattern plate forming apparatus of this embodiment comprises an uneven pattern plate main body and an uneven pattern plate forming machine as in the first embodiment. The uneven pattern plate forming machine is roughly shown in FIG. It is composed of an electrical component (consisting of an information processor and a concavo-convex information transfer controller) and an optical component for concavo-convex information transfer shown in FIG.
FIG. 12 also shows the configuration of the uneven pattern plate main body. The external configuration example of the uneven pattern plate forming apparatus is the same as that shown in FIG. 3 of the first embodiment. FIG. 14 is a flowchart showing a basic process for creating a concavo-convex pattern plate in this embodiment.

First, the electrical components of this embodiment are shown in FIG.
This will be described with reference to FIG.

This electrical component comprises an input unit 10, a control unit 20, and an output unit 30, as in the first embodiment. Since the input unit 10 and the control unit 20 are the same as those in the first embodiment, detailed configurations are omitted.

The output section 30 is composed of an optical component driving circuit group 35 for driving and controlling each component of an optical component for transferring concavo-convex information, which will be described later, and a driving circuit 33 of the display device 34. The circuits 35 and 33 drive corresponding components under the control of the control unit 20. Although the optical component drive circuit group 35 includes various drive circuits, they are collectively shown here. As will be described later, among the components of the optical component, there are various components that require drive control, and in practice, a drive circuit exists for each component.

Next, the configuration of the optical component for transferring the uneven information and the structure of the uneven pattern plate body will be described with reference to FIG.

The uneven pattern plate main body 40 has the same structure as that of the first embodiment. It should be noted that the mounting mechanism for the uneven pattern plate main body 40 (not shown) is movable at a predetermined pitch (line pitch) in the Y direction (sub-scanning direction) shown in FIG.

The optical component for transferring unevenness information includes an ultraviolet irradiation laser light source 60, a beam condenser 61, an optical switch 62, a beam expander 63, a cylinder lens 64,
It is composed of a polygon mirror 65, an fθ lens 66, and an objective lens 67, and each element is arranged in this order.

The ultraviolet irradiation laser light source 60 oscillates and outputs an ultraviolet laser beam during a period in which the control unit 20 instructs the output by a drive circuit (not shown in FIG. 13). is there. The laser beam output in this manner is focused by the beam collector 61 and is incident on the optical switch 62. The optical switch 62 is for interrupting the laser beam by a drive circuit (not shown, reference numeral 35 in FIG. 13), and its control command is issued by the control unit 20. Note that the optical switch 62 can be omitted when the ultraviolet irradiation laser light source 60 itself can control the output and non-output of the laser beam in accordance with the control signal, that is, when it is of a type that outputs the laser beam in a pulsed manner. . The intermittent laser beam is made to have a predetermined spot shape by the beam expander 63, and then is incident on the polygon mirror 65 after the change of the spot shape due to the reflection of the polygon mirror 65 is compensated by the cylinder lens 64. You.

The polygon mirror 65 is rotated at a constant speed by a drive circuit (not shown in FIG. 13 at 35) and a drive mechanism (motor) 68. As is well known, deflection scanning is performed in the X direction (main scanning direction). The rotation of the polygon mirror 65 is also performed under the control of the control unit 20, and is performed in synchronization with the intermittent operation of the optical switch 62 described above. The scanning laser beam reflected by the polygon mirror 65 is converted by, for example, an fθ lens 66 having a toroidal lens configuration so that the scanning speed on the irradiation target (ultraviolet curable resin layer 42b) becomes constant. The ultraviolet-curable resin layer 42b whose surface coincides with the focal plane of the objective lens 67 is irradiated via the objective lens 67 having a heavy spherical lens configuration.

Therefore, the intermittent operation of the laser beam by the optical switch 62 is performed according to the information of one line in the predetermined direction (main scanning direction) of the concavo-convex pattern, and the concavo-convex pattern plate body 40 (accordingly, the ultraviolet curing resin layer 42b) is moved. By repeating the same operation by shifting the line by one line in the sub-scanning direction, it is possible to selectively irradiate only the portion corresponding to the concavo-convex pattern of the ultraviolet curable resin layer 42b with the ultraviolet light. That is, the concavo-convex pattern can be transferred to the ultraviolet curable resin layer 42b.

Next, the operation will be described with reference to FIG. FIG.
When the validity of the mounted concavo-convex pattern plate body 40 is confirmed in step 200 in the same manner as in the flowchart of FIG. 4, the oscillation of the ultraviolet irradiation laser light source 60 is started with the optical switch 62 closed, and The rotation of the polygon mirror 65 is started, and further, the mechanism for driving the concave / convex pattern plate body 40 set at the initial position in the sub-scanning direction is operable. The state is set (step 212). When the laser oscillation and the rotation of the polygon mirror 65 are stabilized, the total number N of scanning lines according to the type of the uneven pattern plate is obtained, and the line position parameter i is set to an initial value (1) (step 213).

Then, the image data (binary data) of the line i of the concavo-convex pattern to be processed is taken out, and the optical switch 62 is turned on and off in synchronization with the rotation of the polygon mirror 65, and the concavo-convex pattern of the line i is changed. UV curable resin layer 42b
Is scanned and irradiated on the position of the line i, and the line i is partially cured (step 214). If the ultraviolet curable resin layer 42b cannot be sufficiently cured by one scan, scanning of the same line may be repeated a plurality of times. When the scan transfer process (curing process) for the line i is completed, it is confirmed that the scan transfer process for all the lines has not been completed, the uneven pattern plate body 40 is moved by one line, and the line parameter i is changed. Increment by one and the above-described step 214 is performed.
(Steps 215 and 216).

By repeating such transfer processing (curing processing) for each line, the processing for all lines is eventually completed, and a positive result is obtained in step 215. At this time, the CPU 21 ends the transfer processing. And the ultraviolet curable resin layer 42 of the uneven pattern plate body 40
A message instructing that b is washed with a predetermined liquid (water) is displayed on the display device 34, and a series of transfer processes of the uneven pattern is completed (step 217).

The creator of the concavo-convex pattern plate cleans the ultraviolet curable resin layer 42b of the concavo-convex pattern plate body 40 after the curing process with a predetermined liquid, thereby removing portions other than the concavo-convex pattern to form the concavo-convex pattern. This completes the uneven pattern plate.

According to the second embodiment, the same effect as that of the first embodiment can be obtained. For example, a person other than a person who is an expert of forming an uneven pattern plate can easily and quickly create a desired uneven pattern plate. Can be obtained.

The present invention is not limited to this embodiment and the above-described embodiments. Some of the modified embodiments related to the second embodiment will be described below. It is.

(11) The transfer in the sub-scanning direction may be performed by moving the entire optical system from the laser light source 60 to the objective lens 67, instead of moving the concavo-convex pattern plate body 40. good.

Further, as shown in FIG. 15, a swing mirror 69 whose angle changes in the sub-scanning direction is provided, and an objective lens 67 is provided.
May be scanned in the sub-scanning direction on the uneven pattern plate main body 40.

(12) The enlargement / reduction of the concavo-convex pattern may be performed by optical processing instead of by information processing. For example, the concavo-convex pattern can be enlarged or reduced by appropriately changing the constant rotation speed of the polygon mirror 65, changing the basic cycle of intermittent switching of the optical switch 62, and changing the feed amount in the sub-scanning direction.

Next, an apparatus for forming a concavo-convex pattern according to a third embodiment of the present invention will be described in detail with reference to FIGS.

In this embodiment, an irregular pattern is printed and transferred to the marking surface member 42 using an ink having a composition that does not transmit ultraviolet rays, and then the ultraviolet rays are irradiated.

The uneven pattern plate forming apparatus of this embodiment comprises an uneven pattern plate main body and an uneven pattern plate forming machine.
7 and a mechanical optical component (a printing unit, a light beam irradiating unit, etc.) shown in FIG. FIG.
Reference numeral 6 also shows the configuration of the uneven pattern plate main body. Also,
FIG. 18 is a plan view of the ink ribbon, and FIG. 19 is a flowchart showing basic processing executed by the control unit of this embodiment.

This electrical component comprises an input unit 10, a control unit 20, and an output unit 30, as in the first embodiment. Since the input unit 10 and the control unit 20 are the same as in the first embodiment, a detailed description of the configuration will be omitted.

First, the output section 30 is composed of a mechanical optical component drive circuit group 35 'for driving and controlling each component of a mechanical optical component described later, and a drive circuit 33 of the display device. , Each drive circuit 35 ′, 33 drives a corresponding component under the control of the control unit 20. Although the mechanical optical component drive circuit group 35 'is composed of various drive circuits, they are collectively shown here. As described later, there are various components requiring drive control among the components of the mechanical and optical components, and in practice, a drive circuit exists for each component.

The mechanical optical components shown in FIG. 16 are mainly composed of a printing configuration and an ultraviolet irradiation configuration.

The printing configuration is based on, for example, a thermal transfer system, and uses the ultraviolet curable resin layer 42b as a printing target. The printing configuration includes a movable print head 70,
Ink ribbon 71 and supply reel 7 for ink ribbon 71
2, a take-up reel 73, and rollers 74 and 75 for changing the traveling direction of the ink ribbon 71.

Under the control of the control unit 20, the movable print head 70 generates heat when the heating driving circuit (see the circuit indicated by reference numeral 35 'in FIG. 17) performs a driving operation, so that the ink on the ink ribbon 71 is irradiated with ultraviolet rays. It is transferred to the cured resin layer 42b, and moves when a moving drive circuit (see a circuit denoted by reference numeral 35 'in FIG. 17) operates under the control of the control unit 20. In the case of this embodiment, the home position P of the movable printing head 70 during the printing standby is selected at a position apart from a region connecting the ultraviolet curing resin layer 42b and an ultraviolet irradiation light source 76 described later,
The irradiation operation described below is not disturbed.

As shown in the plan view of FIG. 18, the ink ribbon 71 is made of a sheet member 7 having a property of transmitting ultraviolet light.
The ink 71b is selectively adhered to the ink lamination area 1a, and a region which is detected by an ink ribbon position detection sensor (not shown) and faces the ultraviolet curable resin layer 42b is the ink adhered region R1 or other transparent region. A mark 71c for identifying the region R2 is provided. Here, the ink 71b is selected to block transmission of ultraviolet rays (for example, black). In addition, the ink attachment region R1
For example, the size of the largest uneven pattern plate body 40 is
Is equal to or larger than the area of the UV-curable resin layer 42b, and the size of the light transmitting region R2 is
It is made equal to or larger than one.

Although the pressing force is applied to the sheet member 71a from the uneven plate body 40 depending on the mounting structure of the uneven pattern plate body 40, the material of the sheet member of the general ink ribbon is more vertical than the material of the sheet member. It is preferable to use one having high resistance to pressing force.

As the ultraviolet irradiation structure, for example, an ultraviolet irradiation light source 76 having a fluorescent lamp structure is provided, for example, in a fixed manner. Note that a lens system or a mirror system for condensing the irradiation light on the ultraviolet curable resin layer 42b may be appropriately provided.

The electric components shown in FIG. 17 described above and FIG.
6 has, for example, an appearance as shown in FIG. 3 of the first embodiment.

Next, the operation will be described with reference to FIG. As in the first and second embodiments, when the validity of the uneven pattern plate main body 40 mounted in step 200 is confirmed, the ink attachment region R1 of the ink ribbon 71 is superimposed on the ultraviolet curable resin layer 42b. After moving
By driving the print head 70, the ink 71b is adhered to the portion of the ultraviolet curable resin layer 42b corresponding to the image obtained by inverting the uneven pattern between black and white and mirror image (steps 222 and 22).
3). Next, after moving the ink ribbon 71 so that the light transmitting region R2 is superimposed on the ultraviolet curable resin layer 42b, the ultraviolet irradiation light source 76 is turned on for a predetermined time (steps 224 and 225).

Finally, the CPU 21 displays, on the display device 34, a message instructing that the transfer process has been completed and that the ultraviolet curable resin layer 42b of the uneven pattern plate main body 40 should be washed with a predetermined liquid (water). Then, a series of concave and convex pattern transfer processing ends (step 226).

The creator of the concavo-convex pattern plate cleans the ultraviolet curable resin layer 42b of the concavo-convex pattern plate main body 40 after such transfer processing with a predetermined liquid, thereby removing portions other than the concavo-convex pattern to form the concavo-convex pattern. Irregularities are formed, and the ink 71b adhering at the time of this cleaning is also removed to complete the irregular pattern plate.

After this, the uneven pattern plate body 40
Is preferably attached again to the concavo-convex pattern plate making machine and irradiated with ultraviolet rays to ensure the resin curing.

Therefore, according to the third embodiment, the creator of the uneven pattern plate does not need to create a negative film, and information corresponding to an original image can be easily created using the key input unit 11. To the extent possible, even a person other than a specialist in the preparation of a concavo-convex pattern plate can easily and quickly produce a desired concavo-convex pattern plate.

Further, according to the above embodiment, since the ink 71b is applied directly to the ultraviolet curable resin layer 42b to irradiate the ultraviolet rays (the shape of the attached ink corresponds to the negative film). The uneven pattern can be accurately transferred as compared with the case where ultraviolet rays are irradiated through the intermediate member.

The present invention is not limited to this embodiment and the above-described embodiments. Some of the modified embodiments related to the third embodiment will be described below. It is.

(13) The printing process on the ultraviolet curing resin layer 42b of the marking surface member 42 may be performed by the fixed head by moving the marking surface member 42 side instead of moving the print head 70.

(14) The supply of the ink ribbon may be performed not in the form of a roll but in the form of a sheet cut to the size of the marking surface. In this case, by discharging the ink sheet after the transfer of the uneven pattern, it is not necessary to provide the above-described light transmitting region R2 in the ink ribbon.

(15) The printing method is not limited to the thermal transfer method, and an ink jet method or a wire dot method may be applied. When the ink jet method is applied, it is considered that the device can be downsized because the drawing of the ink ribbon is unnecessary.

Next, an uneven pattern plate forming apparatus according to a fourth embodiment of the present invention will be described in detail with reference to FIGS.

In this embodiment, instead of printing the concavo-convex pattern plate pattern directly on the engraving surface member 42 as in the third embodiment, a printing process was performed so that ultraviolet rays were partially transmitted in accordance with the concavo-convex pattern. The marking surface member 42b is irradiated with ultraviolet light through the film.

The uneven pattern plate forming apparatus of this embodiment comprises an uneven pattern plate body and an uneven pattern plate forming machine.
This embodiment basically includes the same electrical components as the electrical components shown in FIG. 17 and the mechanical optical components (printing unit, light beam irradiation unit, etc.) shown in FIG. FIG. 20 also shows the configuration of the uneven pattern plate main body. FIG. 21 is a flowchart illustrating basic processing executed by the control unit according to this embodiment.

The electrical components of the fourth embodiment are basically the same as the electrical components of the third embodiment shown in FIG. 17, and a description thereof will be omitted.

The structure of the mechanical optical component will now be described with reference to FIG. The mechanical and optical components shown in FIG. 20 mainly include a printing configuration and an ultraviolet irradiation configuration.

The printing configuration follows the thermal transfer system.
Fixed print head 80, platen roller 81, ink ribbon 82, printing paper ribbon 83, supply reel 84
, A take-up reel 85, and rollers 86 and 87 for changing the traveling direction of the ink ribbon 82.

An ink ribbon 82 and a printing paper ribbon 83 are wound around the supply reel 84 of the fourth embodiment in a superimposed state. The process proceeds to the printing position between the head 80 and the platen roller 81.

Under the control of the control unit 20, the print head 80 generates heat when a heating driving circuit (not shown) is driven to transfer the ink of the ink ribbon 82 to the printing paper ribbon 83.

Here, in the ink ribbon 82 of the thermal transfer system, the transferred portion is depleted of ink and becomes transparent. That is, the transferred ink ribbon 82 includes a portion that can transmit ultraviolet light (a portion from which ink has been removed) and a portion that blocks transmission of ultraviolet light (a portion where ink remains). Therefore, in the fourth embodiment, a printing process is performed on the concavo-convex pattern, and the transferred ink ribbon 82 in which a portion corresponding to the concavo-convex pattern becomes transparent is used as a negative film.

The ink ribbon 82 and the printing paper ribbon 83 in a superimposed state that have passed through the printing section consisting of the print head 80 and the platen roller 81 reach the roller 86, and reach the roller 86 (and the roller 86 and the roller 86). The ink ribbon 82 and the printing paper ribbon 83 are separated by the ribbon separation mechanism (printing mechanism).

After the separated ink ribbon 82 passes immediately below the ultraviolet curable resin layer 42b of the uneven pattern plate main body 40, the traveling direction is changed by a roller 87, and the ink ribbon 82 is taken up by a take-up reel 85. I have. In an optical transfer process of the concave / convex pattern described below for curing the portion corresponding to the concave / convex pattern of the ultraviolet curable resin layer 42b, the area of the ink ribbon 82 where the portion corresponding to the concave / convex pattern is transparent. With the (negative film) positioned directly below the ultraviolet curable resin layer 42b, the ink ribbon 8
2 is stopped.

On the other hand, the printed paper ribbon 83 on which the separated concavo-convex pattern is printed is pulled out of the concavo-convex pattern plate making machine from the discharge opening 88, and cut by a manual or automatic cutter (not shown). The printing paper portion cut in this way is used for checking the uneven pattern.

As the ultraviolet irradiation structure, for example, an ultraviolet irradiation light source 90 having a fluorescent lamp structure is fixedly provided, and the control unit 20 controls turning on and off. Further, the transparent plate 91 which moves forward and backward by a moving mechanism (not shown),
It is provided on the side of the marking surface member 42 opposite to the ultraviolet curable resin layer 42b with the ink ribbon 82 interposed therebetween. That is,
The ultraviolet light emitted from the ultraviolet light source 90 is applied to the transparent plate 9.
1 and the ultraviolet curable resin layer 42 via the ink ribbon 82
b. The transparent plate 91 enhances the adhesion between the ink ribbon 82 functioning as a negative film and the ultraviolet curable resin layer 42b at the advancing position and does not hinder the running of the ink ribbon 82 at the retreating position.

Both ends of the transparent plate 91 in the traveling direction of the ink ribbon 82 are rounded, for example, so as not to damage the ink ribbon 82 at the time of contact. The rounded ends of the transparent plate 91 slightly project from the general surface. When the transparent plate 91 moves to bring the ink ribbon 82 into contact with the engraving surface member 42, the tension is increased and the ink ribbon 82 is brought into close contact. It works to increase sex.

A lens system or a mirror system for condensing the irradiation light on the ultraviolet curing resin layer 42b may be appropriately provided between the ultraviolet irradiation light source 90 and the transparent plate 91.

Further, depending on the mounting structure of the uneven pattern plate main body 40, since a large pressing force is applied to the ink ribbon 82, the resistance to the vertical pressing force is higher than that of a general ink ribbon sheet material. It is preferable that the ink ribbon 82 be formed by a sheet member.

Next, the operation will be described with reference to FIG. When the validity of the mounted concavo-convex pattern plate body 40 is confirmed in step 200 in the same manner as in the above-described embodiment, the print head 80 and the traveling mechanism of both ribbons are driven to execute the concavo-convex pattern printing process. Then, a portion functioning as a negative film is formed on the ink ribbon 82 (step 23).
2).

Thereafter, the printed paper ribbon 83 on which the concavo-convex pattern is printed is discharged and cut, and the negative film functional portion is brought into close contact with the ultraviolet curable resin layer 42b to complete the preparation for optical transfer. Is displayed, prompting the user to instruct whether or not to perform optical transfer, and in response thereto, the contents of the instruction made by the creator of the uneven pattern plate to the key input unit 11 are determined (step 233). 234). For example, the creator of the concavo-convex pattern plate makes a final check whether the size, character shape, etc. are the desired concavo-convex pattern according to the concavo-convex pattern of the cut and discharged printing paper ribbon 83, and if appropriate, optically Direct transfer is specified, and if it is not appropriate, the forced termination of the transfer process is specified. In addition, the uneven pattern displayed on the display device 34 at the time of input of the uneven pattern and the uneven pattern printed to be formed on the marking surface member 42 often differ somewhat in size, pitch between characters, and the like.

When forcible termination is instructed, the CPU 21 immediately terminates a series of transfer processing. On the other hand, when the optical transfer is instructed, the CPU 21 sets the ultraviolet irradiation light source 9.
0 is turned on for a predetermined time (step 235).

Finally, the CPU 21 displays on the display device 34 a message instructing that the transfer processing has been completed and that the ultraviolet curing resin layer 42b of the uneven pattern plate main body 40 should be washed with a predetermined liquid (for example, water). Is displayed, and a series of uneven pattern transfer processing ends (step 23).
6).

The creator of the concavo-convex pattern plate cleans the ultraviolet curable resin layer 42b of the concavo-convex pattern plate body 40 after the above-described transfer processing with a predetermined liquid, whereby portions other than the concavo-convex pattern are removed to form the concavo-convex pattern. The uneven pattern is formed, and the uneven pattern plate is completed.

After that, the uneven pattern plate body 40
Is preferably attached again to the concavo-convex pattern plate making machine and irradiated with ultraviolet rays to ensure the resin curing.

Therefore, according to the fourth embodiment, it is unnecessary for the creator of the uneven pattern plate to create a negative film, and information corresponding to the original image is input to the key input section 11.
A person who is not an expert in the preparation of a concavo-convex pattern plate can easily and quickly produce a desired concavo-convex pattern plate by the amount that can be easily prepared using.

Next, a fifth embodiment, which is a modification of the fourth embodiment, will be described.
Will be described in detail with reference to FIG. Here, FIG. 22 shows the mechanical and optical components (printing unit, light irradiation unit, etc.) of the fifth embodiment, and the same reference numerals are given to the same and corresponding parts as those in FIG. 22 described above. Is shown.

The fifth embodiment is also characterized in that, similarly to the fourth embodiment, a negative film is automatically created by using a printing process. The difference is the biggest difference from the fourth embodiment. The electrical components are almost the same as those of the fourth embodiment, and the fifth embodiment will be described below mainly on the mechanical optical components.

In FIG. 22, the printing paper ribbon 83 of the fifth embodiment is formed of a transparent sheet (in this respect, the expression “paper” may not be appropriate), and the uneven pattern is transferred through the printing process. After being discharged, it travels with the ink ribbon 82 without being discharged to the outside, and reaches the roller 93 via the roller 92. The roller 93 has a ribbon separating mechanism (not shown) and the like, and separates the ink ribbon 82 and the printing paper ribbon 83. Ink ribbon 82 separated and changed in traveling direction
Is taken up by a take-up reel 85.

On the other hand, the printing paper ribbon 83 which has been straightly separated passes immediately below the ultraviolet curable resin layer 42b of the concavo-convex pattern plate main body 40, and then its traveling direction is changed by the roller 94. It is made to be wound up. During the optical transfer processing of the concave and convex pattern described later for curing the portion corresponding to the concave and convex pattern of the ultraviolet curable resin layer 42b, the area of the printing paper ribbon 83 on which the concave and convex pattern is black-and-white inverted is cured by ultraviolet curing. Resin layer 4
The printing paper ribbon 83 is stopped so as to be directly below 2b.

The ultraviolet irradiation structure of the fifth embodiment is the same as the ultraviolet irradiation structure of the fourth embodiment.
The third embodiment is different from the fourth embodiment in that the third embodiment is opposed to the ultraviolet curable resin layer 42b with 3 interposed therebetween.

The processing executed by the CPU 21 is the same as in the fourth embodiment, and a description thereof will be omitted. The uneven pattern image to be printed is the black and white reversed from the uneven pattern image to be printed according to the fourth embodiment.

According to the fifth embodiment as well, a negative film (part of the printing paper ribbon 83) is automatically created through the printing process, and the transfer to the ultraviolet curable resin layer 42b is immediately executed. The same effect as that of the fourth embodiment can be obtained.

May be transferred.

(20) In the fourth and fifth embodiments, the ink ribbon or the printing paper ribbon corresponding to the negative film is transported to the irradiation position in a continuous ribbon shape. And may be transported to the irradiation position.

Printing may be performed at an ultraviolet irradiation position by applying a head, a platen roller, or the like.

(22) By fixing the transparent plate 91 and moving the concave and convex pattern plate body 40 forward and backward, the negative film and the marking surface member may be brought into close contact with each other.

Next, an apparatus for forming a concavo-convex pattern according to a sixth embodiment of the present invention will be described in detail with reference to FIGS.

This embodiment is different from the fourth and fifth embodiments in that the stamping surface member 4 is passed through a thermoreversible light transmittance changing film instead of the film which partially transmits ultraviolet light according to the concavo-convex pattern.
2 is irradiated with ultraviolet rays.

The rugged pattern plate forming apparatus of this embodiment comprises a rugged pattern plate body and a rugged pattern plate making machine.

The thermoreversible light transmittance changing film 100 can be in a light-transmitting state and a non-light-transmitting state (with respect to ultraviolet light) at room temperature, for example, as shown in FIG. Transition to optical state DE-
A is a transition ABCD from the non-light-transmitting state to the light-transmitting state.
Can also be performed by heating and natural cooling.

Recently, a thermoreversible information display film in which display characters are black has been proposed.
Applies to 00.

Thermal head 85 for producing a negative film
For example, a thermoreversible light transmittance changing film 100 in a light transmitting state is run between the platen rollers 86. The thermal head 85 is, for example, similar to a thermal head according to a thermal transfer printing method. Under the control of the control unit 20, the dot elements of the thermal head 85 driven by a heat generating drive circuit (not shown) generate heat. The portion corresponding to the background of the uneven pattern of the thermoreversible light transmittance changing film 100 is selectively changed to a non-light-transmitting state. It should be noted that the thermoreversible light transmittance changing film 100 in the light transmitting state is used.
Is a portion that functions as a negative film.

On the other hand, a heat-reversible light transmittance changing film 100 in which a light-transmitting portion and a non-light-transmitting portion coexist runs on the heat roller 97 for erasing the negative film. The heat roller 97 causes all the portion of the thermoreversible light transmittance changing film 100 that has passed through the roller to be in a light transmitting state. That is, the portion functioning as a negative film is eliminated.

As the ultraviolet irradiation structure, for example, an ultraviolet irradiation light source 90 having a fluorescent lamp structure is fixedly provided, and the control unit 20 controls turning on and off. Further, the transparent plate 91 which moves forward and backward by a moving mechanism (not shown),
It is provided on the side opposite to the ultraviolet-curable resin layer 42b of the marking surface member 42 with the thermoreversible light transmittance changing film 100 interposed therebetween. That is, the ultraviolet light emitted from the ultraviolet light source 90 is applied to the transparent plate 91 and the thermoreversible light transmittance changing film 1.
00, and reaches the ultraviolet curable resin layer 42b. The transparent plate 91 enhances the adhesiveness between the thermoreversible light transmittance changing film 100 functioning as a negative film at the advancing position and the ultraviolet curable resin layer 42b, and the thermoreversible light transmittance changing film 100 at the retreat position. It is made so as not to disturb the running. Both ends of the transparent plate 91 in the traveling direction of the thermoreversible light transmittance changing film 100 are rounded, for example, so that the thermoreversible light transmittance changing film 10 at the time of contact is formed.
0 is not damaged. Also, the transparent plate 91
The rounded both ends slightly protrude from the general surface, and when the transparent plate 91 advances to bring the thermoreversible light transmittance changing film 100 into contact with the marking surface member 42, the tension is increased. Functions to increase adhesion.

A lens system or a mirror system for condensing the irradiation light on the ultraviolet curing resin layer 42b may be appropriately provided between the ultraviolet irradiation light source 90 and the transparent plate 91.

Next, the operation will be described with reference to FIG. When the validity of the concavo-convex pattern plate body 40 mounted in step 200 is confirmed as in the above-described embodiment, the thermal head 85 and the traveling mechanism of the thermoreversible light transmittance changing film 100 are driven, and the like. Thermoreversible light transmittance changing film 1
Only the portion corresponding to the concave and convex pattern of No. 00 is in a light-transmitting state to form a portion functioning as a negative film (step 2).
42).

After that, the thermoreversible light transmittance changing film 10
After the negative film functional portion of 0 is run immediately below the marking surface member 42, the negative film functional portion is brought into close contact with the ultraviolet curable resin layer 42b to complete optical transfer preparation (step 243). The CPU 21 controls the ultraviolet light source 9
0 is turned on for a predetermined time, and when the lighting for a predetermined time is completed, the CPU 21 determines that the transfer processing is completed, and that the ultraviolet curable resin layer 42b of the uneven pattern plate main body 40 is washed with a predetermined liquid (water). The instructed message is displayed on the display device 34 (steps 244 and 245).

Finally, the negative film functional part of the thermoreversible light transmittance changing film 100 is
, And the entire surface is returned to the light-transmitting state, thereby completing a series of transfer processes of the uneven pattern (step 246).

The creator of the concavo-convex pattern plate cleans the ultraviolet curable resin layer 42b of the concavo-convex pattern plate body 40 after the above-described transfer processing with a predetermined liquid, thereby removing portions other than the concavo-convex pattern to form the concavo-convex pattern. The uneven pattern is formed, and the uneven pattern plate is completed.

According to the sixth embodiment, a negative film (a heat-reversible light transmittance changing film 10) is also printed through a printing process.
0 is automatically created and immediately transferred to the ultraviolet curable resin layer 42b.
The same effect as that of the embodiment can be obtained.

By the way, when the uneven pattern plate is created, it may be required to put an outer frame (enclosing frame) on the plate. However, it takes time and effort for the creator of the concavo-convex pattern plate to input the concavo-convex pattern having the outer frame. Therefore, even if the desired concavo-convex pattern has an enclosing frame, the creator of the concavo-convex pattern plate only needs to input the concavo-convex pattern excluding the outer frame. Preferred.

The uneven pattern plate forming apparatus of the seventh embodiment meets such a demand. This seventh embodiment can be applied to any of the first to sixth embodiments with only slight modifications.

There are four types of modes for automatically providing the outer frame with the concavo-convex pattern as follows. That is, (A) an outer frame prohibition instructing means for instructing not to add an outer frame to the concavo-convex pattern is provided, and unless the outer frame prohibition instructing means instructs not to add an outer frame to the concavo-convex pattern, The information processing means automatically adds an outer frame to the captured concavo-convex pattern to obtain a final concavo-convex pattern. (B) Outer frame prohibition instructing means for instructing not to add an outer frame to the concavo-convex pattern is provided. Except when the outer frame prohibition instructing means instructs not to add an outer frame to the concavo-convex pattern, a predetermined physical When applying the characteristic to the resin layer of the resin support member, the characteristic applying means adds the outer frame and performs the application processing. (C) Outer frame indicating means for instructing whether or not to add an outer frame to the concavo-convex pattern is provided. When the outer frame indicating means indicates to add an outer frame to the concavo-convex pattern,
An outer frame is automatically added to the concavo-convex pattern taken in by the information processing means to obtain a final concavo-convex pattern. (D) Outer frame indicating means for instructing whether or not to add an outer frame to the uneven pattern is provided. When the outer frame indicating means indicates to add an outer frame to the uneven pattern, predetermined physical characteristics are obtained. When the applying means applies an application process to the resin layer of the resin support member, the application process is performed by adding an outer frame.

The above requirement can be satisfied by applying one of the four embodiments to the first to sixth embodiments.

Hereinafter, the seventh embodiment will be described in detail with reference to FIGS. 26 to 28. The uneven pattern plate forming apparatus of this embodiment includes an uneven pattern plate main body and an uneven pattern plate creating machine. The uneven pattern plate creating machine mainly includes an electrical component shown in FIG. Transfer control section) and a mechanical section selected from the mechanical and optical components shown in the first to sixth embodiments.

The electrical components shown in FIG. 27 are basically the same as those shown in the first to sixth embodiments, except that an outer frame off instruction unit 14 is newly provided. The outer frame off instruction unit 14 of the key input unit 11 is provided for the first time in this embodiment. In the case of this embodiment, an outer frame is automatically added to the uneven pattern input by the creator of the uneven pattern plate, as described later. This is operated when the addition is prohibited, and is, for example, an instruction effective only for one concavo-convex pattern plate to be created. The outer frame off instructing unit 14 is realized by, for example, an automatic reset type push button.

FIG. 28 is a perspective view showing an example of the appearance of the uneven pattern plate forming apparatus of this embodiment. In this external appearance example, the key input unit 11, the display liquid crystal device 33, and the mounting structure 5 of the concave / convex pattern plate body 40 are provided on the operation panel surface.
5 are arranged in an appropriate city, and the image reading unit 12 is connected to a concavo-convex pattern plate making machine via a cable.
(Note that reference numeral 14 denotes a power supply connection unit.) Next, an example of a process of capturing unevenness pattern information performed mainly by the CPU 21 will be described with reference to FIG.

For example, when the key input unit 11 instructs the processing of acquiring the concavo-convex pattern information, the CPU 21
26 is started, and firstly, the unevenness plate type information is displayed on the display device 33, and the unevenness plate creator selects the unevenness plate information from the key input unit 11. The information of the uneven pattern plate type is taken in (step 300).

Next, if the display device 33 does not require an outer frame, the CPU 21 operates the outer frame off instructing section 14 and then determines whether to input the concavo-convex pattern information by key input or image input. A message prompting the user to instruct whether to input the pattern information by key input or image input immediately if necessary,
Operation information by the creator of the concavo-convex pattern plate is fetched and its contents are determined (steps 301 to 303). If the outer frame off instructing section 14 has been operated, the outer frame off flag is set, and the process proceeds to the determination of the method of inputting the concavo-convex pattern information (step 303).

When the image input is selected as the input method of the concavo-convex pattern information, a message requesting that the original be set in the image reading section 12 and the image reading section 12 be started is displayed on the display device 33, and the image reading section The image data read by 12 is taken in (step 304). Then, the read image and the outer contour of the engraved surface relating to the specified uneven pattern plate type are superimposed and displayed on the display device 33,
Ask for the part to be used for the uneven pattern in the scanned image,
The designated concave / convex pattern portion is fetched (step 305).
For example, when the creator of the concavo-convex pattern plate operates the cursor key of the key input unit 11, the contour display of the engraved surface related to the designated concavo-convex pattern plate type is moved in that direction, and the enter key of the key input unit 11 is pressed. When the operation is performed, the portion of the read image surrounded by the outer contour display of the engraved surface at that time is taken in as the one designated as the concavo-convex pattern.

Thereafter, the value of the outer frame off flag is confirmed (step 306). If the application of the outer frame has not been refused, the irregularities incorporating the outer frame determined according to the type of the irregular pattern plate at that time are used. In addition to the pattern, a final concave-convex pattern image is obtained and displayed on the display device 33, and the process of capturing the concave-convex pattern information ends (steps 307 and 308). On the other hand, when the value of the outer frame off flag refuses to provide the outer frame (when it is set), the outer frame off flag is reset, and the basic operation is performed even when another uneven pattern is captured. The outer frame is added to the display device 3, and then the captured uneven pattern is directly used as the final uneven pattern image on the display device 3.
3 is displayed, and the process of capturing the concavo-convex pattern information ends (steps 309 and 308).

As described above, according to the seventh embodiment, an instruction is given only when an outer frame is rejected, and if no instruction is given, an outer frame is automatically provided. It is possible to increase the creation efficiency in the case of successively inputting the uneven pattern of the pattern plate.

FIG. 29 is a perspective view of a concavo-convex pattern plate prepared according to this embodiment. An outer frame 700 is formed around the uneven pattern plate.

It should be noted that the present invention is not limited to this embodiment and the above-described embodiments. Some modified embodiments related to the seventh embodiment are exemplified as follows. It is.

(23) In the seventh embodiment, the case where the outer frame is automatically added when the concave / convex pattern is fetched has been described. However, the processing for adding the outer frame is not executed when the concave / convex pattern is fetched. The outer frame may be added at the time of producing the negative film (at the time of printing on the engraving surface member 42 in the above embodiment).

(24) In the seventh embodiment, it is assumed that the outer frame is added, and the instruction is given only when the outer frame is not added. However, the instruction of adding or rejecting the outer frame is made by a dip switch or the like. The instruction may be made by weight. In addition, it may be possible to instruct whether or not to add an outer frame for each concavo-convex pattern.

(25) The automatic frame addition function is realized by using an uneven pattern plate forming apparatus employing only the image reading method as the method of inputting the uneven pattern, or employing only the key input method as the method of inputting the uneven pattern. May be provided in an uneven plate forming apparatus.

In the above-described first, third, fourth, fifth, and sixth embodiments, in the case of the concavo-convex pattern plate forming apparatus having the image reading apparatus provided in the apparatus main body, the space divided by the image reading apparatus. And the space occupied by the irradiation configuration of the engraving surface member 42 is large, resulting in an inconvenience that the uneven pattern plate forming apparatus becomes large and expensive. Further, when the image reading configuration is provided, the number of components as a whole increases, and as a result, there is a problem that the failure rate increases.

The eighth embodiment has been made in consideration of the above points, and provides an uneven pattern plate forming apparatus provided with at least an image reading device as information processing means. The same light source unit is used in combination with the light source unit and the light source unit of the light beam irradiation unit.

Hereinafter, the eighth embodiment will be described in detail with reference to FIG. The uneven pattern plate forming apparatus according to the eighth embodiment is characterized by its mechanical and optical components.
Therefore, the mechanical and optical components will be mainly described, and the description of the electrical components will be cited as representative of the fourth embodiment (see FIG. 17), and detailed description will be omitted.

The uneven pattern plate forming apparatus of the eighth embodiment is provided with only an image reading structure as a structure for capturing the uneven pattern, and has an external structure as shown in FIG.

In FIG. 31, the uneven pattern plate forming apparatus main body 1 includes a light beam irradiating component 2 for the uneven pattern plate main body 40, an image reading component 3 for reading an original image (irregular pattern), and a light irradiating component 3 (irregular pattern). A switch group 4 for activating the operations of the optical transfer unit 2 and the image reading unit 3.

FIG. 32 is a schematic sectional view of the light beam irradiation component 2 taken along the line II in FIG.
2, the configuration of the light beam irradiation component 2 will be described. The light beam irradiating component (irregular pattern optical transfer unit) 2 mainly includes a printing configuration and an ultraviolet irradiation configuration.

The printing configuration is basically the same as that of the fourth embodiment of the present invention shown in FIG. Therefore, components denoted by the same reference numerals as those in FIG. 20 are the same components. That is, the fixed print head 80, the platen roller 81, the ink ribbon 82, the printing paper ribbon 83, and the supply reel 84
, A take-up reel 85, and rollers 86 and 87 for changing the traveling direction of the ink ribbon 82.

On the supply reel 84, an ink ribbon 82 and a printing paper ribbon 83 are wound while being superposed.
These ribbons are pulled out from the supply reel 84 in a state of being overlapped, and the print head 80 and the platen roller 8 are pulled out.
Proceed to the printing position between 1.

The print head 80 generates heat under the control of a control unit (not shown) to transfer the ink of the ink ribbon 82 to the print paper ribbon 83.

Here, in the thermal transfer type ink ribbon 82, the transferred portion is depleted of ink and becomes transparent. That is, the transferred ink ribbon 82 includes a portion that can transmit ultraviolet light (a portion from which ink has been removed) and a portion that blocks transmission of ultraviolet light (a portion where ink remains). Therefore, the ink ribbon 82 after the transfer process, in which the portion corresponding to the uneven pattern is made transparent by printing the uneven pattern, is used as a negative film.

The ink ribbon 82 and the printing paper ribbon 83 in a superimposed state that have passed through the printing section composed of the print head 80 and the platen roller 81 reach the roller 86, and the roller 86 (and the roller 86 provided in association with the roller 86) are provided. The ink ribbon 82 and the printing paper ribbon 83 are separated from each other by a ribbon separating mechanism that is used.

After the separated ink ribbon 82 passes immediately below the ultraviolet curable resin layer 42 b of the uneven pattern plate main body 40, the traveling direction is changed by the roller 87, and the ink ribbon 82 is wound by the take-up reel 85. I have. During the optical transfer process of the concave and convex pattern for curing the portion of the ultraviolet curable resin layer 42b corresponding to the concave and convex pattern, the area of the ink ribbon 82 where the part corresponding to the concave and convex pattern is transparent (negative). The ink ribbon 82 is stopped in a state where the film is located immediately below the ultraviolet curable resin layer 42b.

On the other hand, the printed paper ribbon 83 on which the separated concavo-convex pattern is printed is pulled out of the concavo-convex pattern plate forming apparatus main body 1 from the discharge opening 88, and cut by a manual or automatic cutter (not shown). You. The printing paper portion cut in this way is used for checking the uneven pattern. Further, by attaching the cut printing paper portion to the top of the uneven pattern plate main body 40, it is possible to visually recognize what type of engraving surface the uneven pattern plate main body 40 has.

As the ultraviolet irradiation structure, for example, an irradiation light source 90 having a fluorescent lamp structure is provided on a movable mechanism 51 which moves forward and backward in the X direction, and the turning on and off of the light is controlled by a control unit (not shown). A transparent plate 91 that moves up and down by a reciprocating mechanism (not shown) is provided on the opposite side of the marking surface member 42 from the ultraviolet curing resin layer 42b with the ink ribbon 82 interposed therebetween. That is, the light beam (ultraviolet light) emitted from the irradiation light source 90 is transmitted to the transparent plate 91 and the ink ribbon 8.
2 to reach the ultraviolet curable resin layer 42b. The transparent plate 91 includes an ink ribbon 82 functioning as a negative film at the upward movement position and the ultraviolet curable resin layer 42b.
To prevent the ink ribbon 82 from running in the downward movement position.

FIG. 33 is a schematic sectional view of the image reading component 3 taken along the line II-II in FIG.
The configuration of the image reading component 3 will be described with reference to FIG.

The image reading component 3 includes a transparent original image mounting plate 31 on which an original image (concavo-convex pattern) whose writing surface is directed downward is mounted.
0 is provided. The area and shape of the original image placement plate 310 are selected to be substantially equal to, for example, the area and shape of the marking surface member 42 of the largest uneven pattern plate main body 40 that can be handled by the uneven pattern plate forming apparatus main body 1. . When the swinging lid 311 closes the original image placement plate 310, the reading light beam is prevented from leaking outside, so that the quality of the read image is ensured.

Below the original image placing plate 310, the X
An irradiation light source 90 and a one-dimensional photoelectric conversion sensor 312 mounted on a movable mechanism 510 that moves forward and backward in the direction are provided. The one-dimensional photoelectric conversion sensor 312 receives reflected light of the light beam emitted from the irradiation light source 90 from the original image on the original image mounting plate 310, performs photoelectric conversion, and performs original image information (uneven pattern information).
As a serial electrical signal to an electrical processing component (not shown).

FIG. 30 shows that the lid 311 is opened (FIG. 30).
FIG. 2 is a schematic plan view of the uneven pattern plate forming apparatus main body 1 in a state where the uneven pattern plate main body 40 is not mounted.

As shown in FIG. 30, the movable mechanism 510
The one-dimensional photoelectric conversion sensor 312 mounted thereon is extended only below the image reading component 3. However, the irradiation light source 90 mounted on the movable mechanism 510 is extended over both the light beam irradiation component 2 and the image reading component 3, and serves as a light source for image reading, and a marking surface member. The light source unit 42 is also used as a light source unit for light irradiation. When irradiating the marking surface member 42 with a light beam, the irradiation light source 90 may be positioned at a fixed position. When the irradiation light source 90 is fixed, it is more effective to provide a reflector (reflecting plate) so that the light beam diverges.

Here, it is preferable that the irradiation light source 90 contains both ultraviolet light and visible light in the emitted light, and ultraviolet light effectively functions as a light source for irradiating the marking surface member 42 with light. Visible light effectively functions as a light source unit for the reading (a reading unit using ultraviolet light is also conceivable).

In the apparatus for forming a concavo-convex pattern plate having the above-described components, a concavo-convex pattern plate is prepared by the following procedure.

First, the creator of the concavo-convex pattern plate places the original image on which the desired concavo-convex pattern is described on the original image placing plate 310 with the writing surface facing downward, closes the lid 311 and reads the read instruction switch ( Is pressed to instruct image reading. As a result, the image reading component 3 operates to read an image, and the read image information (uneven pattern information) is temporarily stored in a memory (not shown). At the time of this reading, the irradiation light source 90 naturally functions.

Next, the creator of the concavo-convex pattern plate presses the negative film preparation instruction switch (see reference numeral 4),
Instruct creation of a part that functions as a negative film. As a result, the printing process based on the once stored unevenness pattern information is executed by the print head 80, and the printing paper 83 having the same unevenness pattern as the negative film is discharged to the outside, and the ink ribbon 82 functioning as the negative film is printed.
Is conveyed to a position directly below the marking surface member 42 of the uneven pattern plate main body 40.

The creator of the rugged pattern plate having confirmed the rugged pattern embodied in the rugged pattern plate main body 40 by the discharged printing paper 83, attached the rugged pattern plate main body 40 to the rugged pattern plate forming apparatus main body 1, Then, the marking surface member irradiation instruction switch (see reference numeral 4) is depressed to instruct optical transfer of the concavo-convex pattern to the marking surface member 42. At this time, the transparent plate 91 moves upward to bring the ink ribbon 82 functioning as a negative film into close contact with the ultraviolet curable resin layer 42b, and then the irradiation light source 90 emits light for a predetermined time. The irradiation light source 90 may gradually move in the X direction.

With such irradiation, the marking surface member 42
Irradiated portion of the ultraviolet curable resin layer 42b (concave and convex pattern portion)
Cures. For example, during irradiation, for example, L (not shown)
The irradiation indicator lamp of the ED configuration is turned on, and this lamp is turned off at the end of irradiation for a predetermined time. The creator of the concavo-convex pattern plate that has learned of the end of irradiation by turning off the light removes the concavo-convex pattern plate main body 40 from the concavo-convex pattern plate forming apparatus main body 1 and removes the ultraviolet curable resin layer 42 b
Is washed with a predetermined liquid, and the resin portion other than the hardened portion is removed to complete the embossed surface as an embossed pattern plate.

After that, the concave / convex pattern plate main body 40 is mounted again on the concave / convex pattern plate forming apparatus main body 1 and irradiated with light to fix the cured portion, that is, to fix the concave / convex pattern reliably. May be.

Therefore, according to the eighth embodiment, the irradiation light source 90 is used in combination as the light source for the image reading component 3 and the light irradiation component (optical transfer unit for concave and convex pattern) 2. High reliability can be achieved by reducing the number of devices, and downsizing of the device can be achieved by sharing the drive configuration of the light source unit and the like.

Next, a ninth embodiment of an uneven pattern plate forming apparatus according to the present invention, which is a modification of the eighth embodiment, will be described in detail with reference to the drawings. The printing configuration of the ninth embodiment is basically the same as that of the third embodiment of the present invention shown in FIG. Therefore, components denoted by the same reference numerals as those in FIG. 16 are the same components.

The uneven pattern plate forming apparatus of the ninth embodiment is also provided with only an image reading structure as a structure for capturing an uneven pattern, and has an external structure as shown in FIG.
In FIG. 34, the same or corresponding parts as those in the above-described drawings are denoted by the same reference numerals.

In FIG. 34, the uneven pattern plate forming apparatus main body 1 includes a light beam irradiating component 2 for the uneven pattern plate main body 40, an image reading component 3 for reading an original image, and a light irradiating component (a concave and convex optical transfer unit). 2) and a switch group 4 for activating the operation of the image reading component unit 3.
These are arranged on one straight line in the X direction.

FIG. 35 is a schematic sectional view of the light beam irradiation component 2 and the image reading component 3 along the line III-III in FIG. 34. As shown in FIG.
Is similar to that of the eighth embodiment.

The light beam irradiating unit 2 comprises an irradiation light source 90
And a print head 70 mounted on a movable mechanism 71 that moves forward and backward in the direction. This print head 70
In accordance with the ink jet method, printing is performed directly on the ultraviolet curable resin layer 42b of the uneven pattern plate main body 40 (ink is attached). Therefore, the ink attached to the ultraviolet curable resin layer 42b functions as a negative film. In the ninth embodiment, the movable mechanism 510 having the irradiation light source 90 is movable across the light irradiation component 2 and the image reading component 3.

In the ninth embodiment having the above-described structure, the procedure for forming the concavo-convex pattern plate is the same as that in the eighth embodiment, and a description thereof will be omitted.

Therefore, also in the ninth embodiment, the irradiation light source 90 is used in combination as the light source of the image reading component 3 and the light irradiation component (optical transfer of the concavo-convex pattern) 2. High reliability by reducing the number of
Further, downsizing of the apparatus can be achieved by sharing the drive configuration of the light source section and the like.

It should be noted that the present invention is not limited to the eighth and ninth embodiments and the other embodiments described above, but is a modified embodiment related to the eighth and ninth embodiments. Is as follows. In addition, the first to the first, which are not described above,
A modified embodiment related to the ninth embodiment is exemplified as follows.

(26) The features of the eighth and ninth embodiments can be applied to an uneven pattern plate forming apparatus capable of inputting uneven pattern information not only by image reading but also by character input.

(27) Although the processing for taking in the concavo-convex pattern by image reading and the processing for creating the negative film functional portion are performed in a time-sharing manner, these processings may be performed almost simultaneously in parallel. In such a case, the data obtained by the image reading may be immediately transferred to the negative film function part creating unit, and the memory for storing the concavo-convex pattern information may be omitted, or the memory having a small capacity (2 to 2)
About 3 lines) can be applied. Even in this case, the timing of the light beam irradiation for image reading and the light beam irradiation on the marking surface member are different, and the irradiation light source is changed as in the eighth and ninth embodiments. Can be used together.
