This UV curable resin liquid is supplied to the transfer roll 402 by rotation of the pickup roll 401, and is applied to the gap between the transfer roll 402 and the back roll 403 when the photosensitive material 2 is passed through.

The transfer roll 402 is made of rubber, and the pickup roll 401 and back roll 403 are made of metal. This pickup roll 401 has a rough surface.
The amount of V-curing resin liquid pumped up can be controlled, and the surface of the back roll 403 is also made rough, so that the photographic light-sensitive material 2
This makes it easy to transport.

The pickup roll 401 is movable, and the contact pressure with the transfer roll 402 can be adjusted. Further, a predetermined gap is formed between the back roll 403 and the transfer roll 402, and this gap is also formed between the back roll 403 and the transfer roll 402.
It can be adjusted by moving the thickness of the photosensitive material 2, and is set to be smaller than the thickness of the photographic material 2. When the thickness of the photographic material 2 is, for example, 500 μm, the gap is set to about 250 μm.

The temperature control means of the control unit H controls the heater 405 to control the UV curable resin liquid to a predetermined temperature higher than room temperature, for example, 37°C.

For example, 100 cc of UV curable resin liquid is stored in the vat 400, and a heater 4 heats this UV curable resin liquid.
As shown in FIG. 5, it is preferable to provide 05 on the outside bottom of the vat 400 so that it can be heated uniformly, but it may also be provided in the liquid inside. Further, the heater 405 is not limited to a plate-shaped one, but may be a rod-shaped one, and the bat 405 may also be a rod-shaped one.
It is also possible to provide it on the side of 00, and the arrangement position is not particularly limited.

The temperature detection sensor 406 is, for example, a thermistor, but is not limited to this, and as shown in FIG.

The tip of the supply pipe 407a of No. 7 is opened by cutting diagonally, and when the liquid level of the UV curable resin liquid in the vat 400 decreases, the UV curable resin liquid is automatically supplied from the replenishment tank 407.

Coating conditions for the UV curing resin liquid In this coating mechanism, by setting the coating conditions for the UV curing resin liquid, a pattern can be created when the UV curing resin liquid is applied to the photographic material, and a three-dimensional pattern can be created by curing the UV curing resin liquid. A protective layer 3 having a pattern can be formed.

The coating conditions include the coating speed of the UV curing resin liquid, the UV
There are the viscosity of the cured resin liquid, the relative speed of the transfer roll and the pickup roll, etc., and these coating conditions will be explained below.

Transfer roll and pick-up roll When the rotational speeds of the transfer roll 402 and the pick-up roll 401 are the same, a three-dimensional pattern is formed by setting the coating speed and the viscosity of the UV curing resin liquid to predetermined values.

In addition, a transfer roll 402, a pickup, a roll 401
It is also possible to form a three-dimensional pattern by providing a gap between the two and using a separate drive source to change the rotational speed of the two.

For example, a matte rubber roll is used as the transfer roll 402, and the surface roughness thereof is preferably in the range of 20 μm to 40 μm, for example.

Further, the film thickness of the UV curing resin liquid on the transfer roll 402 is I
Depending on the type of D card, etc., the thickness is controlled to always be a predetermined thickness, for example, in the range of 1 to 30 μm. In this embodiment, the film thickness on the transfer roll 402 is controlled to be 3 to 10 μm.

Coating speed By controlling the rotational speed of the transfer roll 402, the coating speed is set to tm.
/min or higher and the coating speed is increased, a remarkable three-dimensional pattern is formed by the protective layer.

Viscosity of UV curable resin liquid The viscosity of the UV curable resin liquid is set to, for example, 100 cp or more. The viscosity of this UV curable resin liquid is temperature dependent as shown in FIG. 6, and a predetermined viscosity can be obtained by controlling this temperature. As described above, the temperature of this UV curable resin liquid is controlled to be higher than room temperature, for example, 37°C, thereby adjusting the viscosity of the UV curable resin liquid.

For temperature control of the UV curable resin liquid, for example, it is preferable to compare the actual measured temperature with a set value and control the set temperature based on the difference, as this enables precise temperature control. However, the heater 405 is turned on, 0FFL,
It may also be controlled to maintain a predetermined temperature.

An example of a three-dimensional pattern formed on the protection N3 of the ID card I is shown in FIGS. 7 and 8.

The LIV lamp 501 uses, for example, a high-pressure mercury lamp, and the lamp house 502 is formed into a box shape with an opening at the bottom. A vent (not shown) is formed in the lamp house 502 to easily draw air into the lamp house 502. This improves the cooling efficiency of the UV lamp 501.

The UV lamp 501 has a reflecting mirror 503, which irradiates the photographic material 2 with ultraviolet rays, and the longitudinal direction of the UV lamp 5o1 is arranged along the transport direction of the photographic material 2. . When the photosensitive material 2 is conveyed by the conveyor belt 304, the time for passing the ultraviolet rays from the UV lamp 501 becomes longer, and the curing of the UV curing resin liquid can be accelerated.

The UV irradiation chamber 500 is partitioned with a heat insulating material and has an irradiation window 50.
4 is provided with a cold filter 505 to block the heat of the UV lamp 501 from being transmitted to the outside. U
An air inlet 507 is formed in the lower part of the V irradiation chamber 5oo via a filter 506, and an air exhaust port 509 having a fan 508 is formed in the upper part, thereby forming an air passageway that circulates air from the lower part to the upper part. There is.

With the air passage formed in this UV irradiation chamber 500, the UV clamp 01 itself is directly cooled, and the UV irradiation chamber 500
The heat insulating material that separates the UV lamp 501 from being transmitted to the outside reduces the thermal influence on the UV curable resin liquid at the application area, and the area close to the application area This makes it possible to arrange the device in a smaller size.

Embossed part F In this invention, an embossed part is not necessary because a three-dimensional pattern is formed by curing the UV-cured resin liquid in the above process, but in this embodiment, an embossed part is further provided after the UV irradiation part E. F is placed on the protective layer 3, on which a three-dimensional pattern is formed by curing the UV curing resin liquid, and an emboss of a predetermined shape is further formed to prevent imitation and theft of the ID card ■. There is.

This emboss is formed when the photographic material 2 is heated with an embossing roll 600 placed above and passed between it and the back roll 601, and is formed only on the protective layer 3 of the photographic material 2. This prevents the image area from being scratched.

Air Conditioning Unit G An air conditioning unit G is disposed above the UV irradiation unit E, and is used to air condition the inside of the device main body 1 to cool and clean the air and to create a positive pressure. This air conditioning section G includes a fan 700 and filters 701 and 702 placed before and after this fan 700.
