[0003] As an example, Japanese Patent Application Laid-Open No. H10-50700
In Japanese Patent Application Publication No. 5 (1999) -1995, a pair of sheet rolls each formed by winding a pair of sheets for laminating the front and back surfaces of a sheet are rotatably supported and arranged at upper and lower positions in a sheet cassette. The cassette is detachably mountable to a sheet supply unit of the apparatus main body.

In the apparatus main body, a pair of upper and lower nipping rollers is disposed on the sheet discharge side of the sheet cassette, and the two nipping rollers are configured to rotate in synchronization with rotation of an outer handle. .

[0005] Then, the paper placed on the paper feed tray is supplied close to and between the upper and lower sheet rollers, and the upper and lower sheets are pulled out by the sandwiching rollers, and the sheets are sandwiched between them and laminated. . When the laminate thus formed is cut in the X direction (a direction perpendicular to the paper transport direction) by a horizontal cutter blade, a paper laminated with a sheet such as a PET film (laminate)
Is obtained.

However, in the above-described conventional apparatus, it is troublesome to manually perform the operation of placing the sheets to be stacked on the sheet feed tray and inserting the sheet up to the joining portion of the upper and lower two sheets in the sheet cassette. There was a problem.

Therefore, the present applicant has previously filed Japanese Patent Application No.

In the laminating apparatus 1 of the present embodiment, as described above, the sheet S1 has a transparent resin film layer as a base material, and an adhesive layer is laminated on one surface thereof. In the case of a pattern layer, a sheet S1 composed of a film layer and an adhesive layer is pressed against the front side of the paper P, and the film layer is adhered to the surface of the paper P by the adhesive layer. On the other hand, the sheet S2 is pressed against the back of the sheet P, but does not adhere to the sheet P because the sheet S2 is only the release paper layer.

When the width of the sheets S1 and S2 is made larger than the width of the sheet P, the sheets S1 and S2 protrude from the sheet P in the width direction of the sheet P. Then, at the protruding portion, the adhesive layer of the sheet S1 and the release paper layer of the sheet S2 adhere to each other, and the sheets S1, S2 and the sheet P are substantially integrated into a laminate.

Then, the laminate R is sent to the cutting section D.

In the laminating apparatus 1 of the present embodiment, when the width of the sheets S1 and S2 is excessively large with respect to the width of the paper P, the vertical cutting mechanism is used to set an excessively large edge portion to an appropriate edge width. cut out. Further, the feeding of the laminate R proceeds to a predetermined position in the Y direction of the paper P, and the laminate R
When the predetermined position reaches the cutting position by the horizontal cutting mechanism, the laminate R is cut in the X direction.

In the laminate R thus produced, a transparent film layer is laminated on the surface of the paper P, and a release paper layer exists on the back surface of the paper P in a non-adhered state.
1 and S2, and the transparent film layer F and the release paper layer are bonded to each other at the protruding portion in such a manner that the release film layer is easily peeled off.

When the laminate R thus laminated is to be attached to a wall or the like, the release paper layer on the back surface is rolled up. As a result, the adhesive layer of the sheet S1 is exposed around the sheet P. Therefore, the laminate can be attached to a desk or the like.

In another embodiment, the same sheet (laminated sheet of a resin film layer and an adhesive layer) as in the previous embodiment is used as the sheet S1, and a magnetic sheet is used as the sheet S2. In one embodiment of the magnetic sheet, a magnetic sheet is used as a base material, and an adhesive layer is laminated on one surface thereof. Examples of the magnetic sheet serving as a base material include a magnetic sheet obtained by kneading a magnetic material in rubber or synthetic resin.
