Claims

[Scope of Claim for Utility Model Registration] (1) In a fixing device of a printer equipped with a heat roller, a stop detection sensor detects the stopped state of continuous paper, and a heat roller is placed in a contact position or a non-contact position with respect to the continuous paper. A fixing device for a printer, comprising: a displaceable actuator for displacing a roller; and a control means for controlling the actuator so that the heat roller is in a non-contact position when a stop state is detected by at least a stop detection sensor. . (2) The printer according to claim 1, wherein the heat roller comprises a pair of driving heat roller and driven heat roller that sandwich the continuous paper, and the driven heat roller is displaced relative to the driving heat roller. fixing device. (3) A claim characterized in that a guide member for the continuous paper is arranged so that the continuous paper is in a non-contact position with both the drive-side heat roller and the driven-side heat roller at the non-contact position of the heat roller. A fixing device for the printer according to item 2.
