Abstract: A document sheet issuing system suitable for manufacturing a product based on an ordering by a retailer issues a plurality of documents, e.g., guarantee card, user registration card, on which data including a name of retailer is printed during manufacturing. The issued documents are attached to a carton box in which manufactured product is packed before the product is delivered to thereby reduce troublesome operation by the retailer. The system uses a laminated medium including a lower document sheet and an upper document sheet peelably laminated on the lower sheet. A first data is printed firstly on the lower sheet through the upper sheet and a second data different from the first data is then printed on the upper sheet.

Abstract: A multicolor thermosensitive recording medium according to the present invention comprises a first thermosensitive coloring layer which develops by the application of coloring energy, and a second thermosensitive coloring layer which develops in a different color from the first thermosensitive coloring layer by the application of coloring energy. At least one of a region wherein only the monochrome color of the first thermosensitive coloring layer is obtained without coloring the second thermosensitive coloring layer, and a region wherein only the monochrome color of the second thermosensitive coloring layer is obtained without coloring the first thermosensitive coloring layer, is provided in a printing region of the multicolor thermosensitive recording medium of the present invention.

Abstract: A thermal print head comprising a sequential laminated arrangement of an insulating substrate, a heating resistance layer, an electrode layer formed in a predetermined pattern, and a protective layer. The protective layer is formed of a mixture of Al.sub.2 O.sub.3 as a principal component, and SiO.sub.2. The protective layer has satisfactory heat resistance, abrasion resistance, crack resistance, moisture resistance and chemical stability.
