2. Description of the Related Art As a conventional bookbinding file of this type,
It is known that the back cover is coated with a thermoplastic adhesive, and as a bookbinding machine that binds this file, it has a heating means and a file support part that supports the bookbinding file on the heating surface side of this heating means. However, there is known a structure in which the material is bound in the bookbinding file by heating the thermoplastic adhesive applied to the back of the bookbinding file by a heating means (Actual Development Sho 60- (See 102960 publication).

[0003]

However, in the conventional bookbinding machine of this type, a heater is used as a heating means, the thermoplastic adhesive is melted by the heater, and then the adhesive is cooled to cure the adhesive. Since the bookbinding is performed, there is a problem that it takes time to reach the temperature at which the adhesive can be bound and the binding can be performed, and further, the bookbinding material must be left to stand until the molten adhesive is cured. Further, since the heat from the heater is blocked by the base material of the file, it takes a long time to melt the thermoplastic adhesive, and there is a problem that the bookbinding efficiency is poor. Furthermore, since the heated portion becomes hot, there is a problem in terms of safety.

The present invention has been made in view of the above circumstances, and a bookbinding file and a bookbinding file capable of bookbinding by curing the adhesive in a short time without raising the heating source of the heating means more than necessary. It is intended to provide the bookbinding machine.

It is characterized in that at least a portion of the spine cover to which the adhesive is applied is formed of an ultraviolet ray transmissive member, and the adhesive is an ultraviolet curable adhesive.

In the first aspect of the invention, the ultraviolet-transmissive member is not a thermoplastic such as a transparent plastic film or an inorganic film (for example, mica film) or an organic film (for example, cellophane) having relatively good ultraviolet-transmissivity. (Including films, etc.) and the like can be used.

As the UV-curable adhesive, for example, a UV-curable adhesive composed of a (meth) acrylic monomer, a urethane (meth) acrylate oligomer, a (meth) acryloylated polymer or various polymers can be used.

As the above-mentioned ultraviolet ray opaque member, for example, paper, opaque plastic film, cloth, non-woven fabric, ceramic, metal, or a composite material thereof can be used.

Further, the bookbinding machine of the second invention is premised on the bookbinding machine in which the material is bound in the bookbinding file according to claim 1 or 2, and the file is formed by an ultraviolet-transparent member. Substrate, a file support portion facing the file installation substrate, and an ultraviolet irradiation means arranged on the opposite side of the file installation substrate from the file installation side.

In the second aspect of the present invention, the file setting substrate may be any one as long as it is formed of an ultraviolet transparent member, and can be formed of, for example, highly transparent transparent glass. ..

As the ultraviolet irradiation means, for example, an ultraviolet lamp such as a high pressure mercury lamp or a metal highland lamp, an electrodeless discharge tube or the like can be used.

Further, the file supporting part may be fixed as long as it supports the bookbinding file on the side of the installation substrate, but preferably at least one is movable back and forth with respect to the other. It is better to be composed of a pair of supports. More preferably, a detection means for detecting the presence / absence of a file is provided on the file support side of the file support part, the signal from this detection means is controlled by the control means, and the output signal is an ultraviolet irradiation means and a display. Better to communicate to the means.

[0013]

According to the present invention having the above-mentioned structure, the ultraviolet ray radiated from the ultraviolet ray radiating means is radiated to the ultraviolet ray curable adhesive through the file setting substrate and the ultraviolet ray permeable member of the file. The UV curable adhesive cures and the material can be glued into the file.
Further, since it is a curing method using ultraviolet rays, the heating temperature is not raised more than necessary, so that the safety can be improved.
