Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for forming a protective layer of an ID card for applying a UV curable resin liquid of a card-shaped photographic material.

[Conventional technology] ID cards are student ID cards, ID cards, credit cards,
It is used for a driver's license and the like, and image information such as a photograph of a face and / or visible information such as a name, an address and other characters, symbols, and signs are recorded on a card surface in a photographic manner.

The applicant has made various studies on the creation of an ID card by this photographic method, for example, Japanese Utility Model Publication No. 45-28144, Japanese Patent Application Laid-Open No. 49-123016, Japanese Patent Application No. 55-17577, and Japanese Patent Application No. 59-15923.
No. 59-17546, Japanese Patent Application No. 58-45819, No. 58-45820
No. 58-53844. These are directly photographed on a roll of photographic photosensitive material by a photographing machine, processed by an automatic developing machine, and the laminate is adhered to the photographic photosensitive material by an automatic laminating and cutter machine and cut into ID card size. .

[Problems to be Solved by the Invention] By the way, as disclosed in Japanese Patent Application No. 59-200521 by the present applicant, a photographic photosensitive material is cut into an ID card size from the beginning, and a UV curable If the resin liquid is used, the ID card is completed immediately after the UV-curable resin liquid is cured without using a conventional cutter.

Therefore, since the cutter machine is unnecessary, the size of the apparatus is reduced, and the step of cutting the ID card into a size is omitted, so that the ID card can be created in a short time.

In this way, even when using a card-shaped photographic photosensitive material, after similarly capturing and developing image information, a UV curable resin liquid is applied, and in order to cure this UV curable resin liquid, Irradiation with ultraviolet light is performed.

This UV-curable resin liquid is applied by transferring a card-shaped photographic photosensitive material between a transfer roll and a back roll in an application section and transferring the UV-curable resin liquid from the transfer roll. Since the material is formed in a card shape, application is performed intermittently. Therefore,
It is necessary to make the film thickness of the UV curable resin liquid of the transfer roll constant, but it is difficult to directly measure and control this film thickness. By the way, the film thickness of the UV curable resin liquid of the transfer roll depends on the coating speed and the viscosity, but since this coating speed is sometimes limited by the relationship with the speed at which the ID card is created, the UV It is easier to control the viscosity by controlling the temperature of the curable resin liquid.

The temperature at the time of application of this UV-curable resin liquid is preferably room temperature or higher, but when this temperature is controlled, for example, a UV-curing part for curing the UV-curable resin liquid applied to the photographic photosensitive material in the apparatus body is used. The temperature rises during operation, which may cause the temperature of the UV curable resin liquid to exceed the control range, making it difficult to apply the UV curable resin liquid uniformly.

The present invention has been made in view of the above points, and controls the temperature of a UV-curable resin liquid under an appropriate environmental condition, and adjusts the film thickness at the time of application to uniformly coat a card-shaped photographic light-sensitive material. An object of the present invention is to provide an apparatus for forming a protective layer of an ID card, which enables coating, makes the protective layer uniform, further improves the quality of the ID card, and further reduces the size of the apparatus.

Means for Solving the Problems In order to achieve the above object, the present invention provides an ID having an application unit for applying a UV curable resin liquid to a card to be conveyed.
In the card forming apparatus, the coating unit is partitioned by a heat insulating material inside the apparatus, and a UV having an air introduction port for introducing air from outside through a filter, and an air exhaust port for discharging air to the outside via a fan. The irradiation chamber is provided with a UV lamp, and has a UV irradiation unit for irradiating ultraviolet rays to cure the UV curable resin liquid applied to the card, and to apply UV to the card.
Heating means for heating the curable resin liquid, temperature detection means for detecting the temperature of the UV-curable resin liquid, and driving the heating means based on temperature information obtained from the temperature detection means, thereby curing the UV-curable resin liquid. Temperature control means for controlling the temperature of the conductive resin liquid to a predetermined temperature equal to or higher than room temperature.

The above UV irradiation section is made of heat insulating material that partitions the UV irradiation chamber.
In addition to blocking the heat of the UV lamp from transmitting to the outside,
Since the UV lamp is cooled by driving the fan by connecting the air passage to the outside of the device body, the thermal effect on the UV curable resin liquid in the application section is reduced, and the environment becomes appropriate and the UV irradiation section is applied. And it can be arranged in close proximity.

Under this appropriate environmental condition, by further controlling the temperature of the UV-curable resin liquid according to the application conditions, its viscosity can be adjusted, enabling uniform application to the card and uniform protection layer. As a result, the quality of the ID card is further improved, and the size of the device is reduced.
