Abstract:
1. A method for producing a reversible thermosensitive recording medium, the method comprising: (a) conveying an inlet sheet which includes inlets each of which has a convex-shaped electronic information recording element and an antenna circuit on a circuit board, (b) retrieving positional information of the nlets by detecting the position of the inlets in the inlet sheet, (c) cutting the inlet sheet into individual inlets based on the positional information of the inlets, (d) retrieving positional information of the convex-shaped electronic information recording element in the individual inlets on a vacuum suction roller which is rotatable with the individual inlets being adsorbed on a surface thereof, (e) conveying a base sheet, which comprises a reversible thermosensitive recording layer and a plurality of concave portions in a surface thereof opposite to a surface thereof on which the reversible thermosensitive recording layer is provided, toward the vacuum suction roller, (f) retrieving positional information of each of the concave portions in the base sheet by detecting the position of the concave portion, (g) aligning the convex-shaped electronic information recording element with the concave portion based on the positional information of the convex-shaped electronic information recording element and the positional information of the concave portion, so that the convex-shaped electronic information recording element is inserted into the concave portion, and (h) laminating the inlets and the base sheet by allowing the base sheet to pass between the vacuum suction roller and a lamination roller after the aligning, wherein the detecting in (f) of the position of the concave portion is performed by a concave portion-detection sensor which detects the concave portion of a register mark indicating the position of the base sheet and outputs positional information of the concave portion which includes difference information between the position of the detected concave portion and a reference position of the concave portion set by a size of the base sheet or a pitch interval between the concave portions arranged adjacent to each other.
