Thermal activation device and method of conveying sheet material

摘要

Provided is a thermal activation device including a thermal activation head (11) for thermally activating a heat-sensitive adhesive layer of a sheet material (3), a platen roller (12) for holding and conveying the sheet material (3), the platen roller (12) being brought into press contact with the thermal activation head (11), and a pair of conveyor rollers (14a and 14b) that convey the sheet material (3), the conveyor rollers (14a and 14b) being provided to be located on an upstream side of the thermal activation head (11) in a conveying direction of the sheet material (3). Holding force for the sheet material (3) by the pair of conveyor rollers (14a and 14b) is made larger than holding force for the sheet material (3) by the platen roller (12) and the thermal activation head (11).
