Abstract:
1. A thermally activating device, comprising: a carrying-in section into which a heat-sensitive sheet is carried from a device at an anterior stage; and a heater section for heating the carried heat-sensitive adhesive sheet while conveying the heat-sensitive adhesive sheet; wherein the thermally activating device bends the heat-sensitive sheet toward one surface side thereof in a region between the carrying-in section and the device at the anterior stage by changing between a speed at which the heat-sensitive adhesive sheet is carried out of the device at the anterior stage and a carrying-in speed thereof in the carrying-in section; wherein the carrying-in section comprises a pair of conveyor rollers that convey the heat-sensitive adhesive sheet while sandwiching the heat-sensitive adhesive sheet therebetween; and a guide member provided at an anterior stage of the pair of conveyor rollers for abutting on one surface of the heat-sensitive adhesive sheet to guide a path of the heat-sensitive adhesive sheet; wherein a guide tip end nearest the conveyor rollers on a guide surface of the guide member is disposed at a position displaced from a reference line in a direction opposite to a side toward which the heat-sensitive adhesive sheet bends when viewed from a rotation axis direction of the conveyor rollers, the reference line being a tangential line of the conveyor rollers and passing through a contact point of the pair of conveyor rollers; and wherein the guide tip end is displaced from the reference line by a length of R×0.05 to R×0.3, where R is a diameter of the conveyor roller on a side to which the guide tip end is displaced, an inclination at a portion of the guide tip end of the guide surface is set at 0° to 17° with respect to the reference line, and the guide tip end is disposed at a position spaced apart by R×0.25 to R×0.75 from a plane including respective rotation axis lines of the pair of conveyor rollers.
