Printer and adhesive label manufacturing device

An adhesive label manufacturing method comprising:

• a printing step of a printing device heating and printing a printing enabled layer of a heat-sensitive sheet provided by forming the printing enabled layer on one face of a sheet base material and forming a heat-sensitive adhesive layer on the other face;
• a cutting step, following the printing step, of a cutting device cutting the heat-sensitive adhesive sheet to a predetermined length;
• and
• a thermal activation step, following the cutting step, of a thermal activation device heating and thermally activating the heat-sensitive adhesive layer;
• a step, preceding the cutting step, of deflecting the heat-sensitive adhesive sheet downward, so as to form a concave shape between the cutting device and the thermal activation device, until a portion, extending from the leading edge of the heat-sensitive adhesive sheet, which is delivered to the cutting device from a delivery point, to a portion facing the cutting device reaches a desired length for an adhesive label,
• whereby the step of deflecting the heat-sensitive adhesive sheet downward into a concave shape includes a step of
• conveying the heat-sensitive adhesive sheet so that the leading edge abuts against a guide roof member, a flat plate positioned above the sheet path and extending from the delivery point for the cutting device to an insertion point for the thermal activation device, the position of which is lower than the delivery point, and sliding the heat-sensitive adhesive sheet, while in contact with the guide roof member, so as to introduce the heat-sensitive adhesive sheet to the entrance of the thermal activation device.
