PURPOSE:To perfectly prevent a continuous sheet from being heated or being burnt at the time of not printing by forming the device so that the tension can be impressed on the continuous sheet at the time of separating a pressurizing roller and separating the continuous sheet from the heating roller and the pressurizing roller. CONSTITUTION:The heating roller 1 is rotatably disposed within an upper frame 8, and the pressurizing roller 2 is disposed within a lower frame 9 so that it can freely rotate within a movable frame 11 which is turnably formed through a shaft 10, and the pressurizing roller 2 is formed so as to freely press-contact to and separate from the heating roller 1. The contact part of the heating roller 1 and the pressurizing roller 2 is disposed above a flat plane including a terminal end on the downstream side of a paper entering guide 3 and the contact part between paper ejecting rollers 4. The tension can be impressed on the continuous sheet 6 at the time of separating the pressurizing roller 2, and the sheet 6 can be separated from the heating roller 1 and the pressurizing roller 2. Thus, the sheet 6 can be surely separated from the heating roller 1 and can be perfectly prevented from being heated or being burnt caused by a heat transfer from the heating roller 1 at the time of not printing. |
