  • Patent number: 9283799
    Abstract: A method for producing a thermoreversible recording medium, containing: arranging inlets on a first base sheet to be spaced apart from each other by predetermined intervals to produce a first sheet having a product portion including the inlets and end portions at both ends of the product portion; applying an adhesive onto a second base sheet using an adhesive application unit, to produce a second sheet; passing the first sheet and the second sheet through a gap between a pair of gap rollers in the manner that the inlets and the adhesive face to each other to laminate the first sheet with the second sheet, while forming an adhesive liquid pool in an upstream of the gap; and feedback controlling an amount of the adhesive to be applied in the applying so that the adhesive liquid pool does not flow into the end portions on the first sheet.

  • Patent number: 8778107
    Abstract: The present invention provides a method for producing a reversible thermosensitive recording medium, the method including: conveying an inlet sheet which includes inlets each having a convex-shaped electronic information recording element, retrieving positional information of the inlets, cutting the inlet sheet into individual inlets, retrieving positional information of the convex-shaped electronic information recording element in the individual inlets, conveying a base sheet, which includes concave portions, toward the vacuum suction roller, retrieving positional information of the concave portions, aligning the convex-shaped electronic information recording element with the concave portions so as to be inserted into the concave portion, and laminating the inlets and the base sheet.

  • Patent number: 8541339
    Abstract: A reversible thermosensitive recording medium including: reversible thermosensitive recording layer; first sheet-shaped base; second sheet-shaped base; first resin layer; second resin layer; and electronic information recording module containing module substrate, and electronic information recording element and antenna circuit disposed on the substrate, wherein the recording layer is provided adjacent to the first sheet-shaped base; the first or second sheet-shaped base has concave portion in which the element is disposed in depth direction thereof; the module is provided between the first and second sheet-shaped bases, where the first resin layer is provided between the module and the sheet-shaped base having the concave portion and the second resin layer is provided between the module and the sheet-shaped base having no concave portion; and inner side surface of the concave portion is tapered surface where maximum opening diameter of the concave portion decreases from opening edge thereof towards bottom sur

  • Patent number: 8450240
    Abstract: A reversible thermosensitive recording medium including a reversible thermosensitive recording layer, a first sheet-shaped base provided adjacent to the reversible thermosensitive recording layer, an electronic information recording module containing a module substrate, and a convex-shaped electronic information recording element and an antenna circuit both disposed on the module substrate, and a first resin layer for bonding the first sheet-shaped base and the electronic information recording module, wherein the first sheet-shaped base has a concave portion on a surface opposite to a surface on which the reversible thermosensitive recording layer is formed, and the electronic information recording element is inserted into the concave portion of the first sheet-shaped base.
