Method for producing thermoreversible recording medium and apparatus for producing the same

An apparatus for producing a thermoreversible recording medium, comprising:

• a first sheet production unit configured to arrange inlets to be spaced apart from each other by predetermined intervals, on a first base sheet that additionally includes a thermosensitive recording layer, to thereby produce a first sheet having a product portion including the inlets and end portions at both ends of the product portion;
• a second sheet production unit configured to apply an adhesive onto a second base sheet using an adhesive application unit, to produce a second sheet;
• a lamination unit configured to pass 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
• a control unit configured to feedback control an amount of the adhesive to be applied so that the adhesive liquid pool does not flow into the end portions on the first sheet.
