    • PURPOSE:To reduce cooling load and, then, to miniaturize a device by providing a by-pass linking a path for reflux and an introducing path and by making gas by- pass in case when a transfer paper is not yet conveyed in a fixing an drying part. CONSTITUTION:In case when a transfer paper (p) is conveyed in a housing 5, hinged valves 88, 89 are turned to solid positions through a detection output of a sensor S1 for detecting a front end of paper, and circulating gas which is made high temperature in a heat exchanger 83 and is flowed into the housing 5 through an inlet 5a for air, then a treatment for fixing and drying is performed by contacting this air with the paper (p). In case when the paper (p) undergone the fixing and drying treatment is ejected from the housing 5, the valves 88, 89 are turned to broken lined positions through a detection output of a sensor S2 for detecting a rear end of paper. As a result, the circulating movement of the gas returning from the housing 5 into the housing 5 by way of the heat exchanger 83, a cooler 84, a suction fun 82 and the heat exchanger 83 is made to stop, then, the gas which is in a path joining from the suction fun 82 to the cooler 84 by way of a by-pass 87 only is circulating.
    • 目的:为了减少冷却负荷,然后通过提供旁通连接回流路径和引入路径并通过在转印纸尚未在固定中传送的情况下进行气体旁路来减小冷却负载 干燥部分。 构成:如果在壳体5中输送转印纸(p)的情况下,铰链阀88,89通过用于检测纸张前端的传感器S1的检测输出和循环气体被转动到固定位置 热交换器83中的高温通过用于空气的入口5a流入壳体5,然后通过使该空气与纸(p)接触来进行固定和干燥处理。 在经由定影干燥处理的纸(p)从壳体5喷射的情况下,通过用于检测纸张后端的传感器S2的检测输出,阀88,89转动到分开的位置。 结果,使通过热交换器83,冷却器84,抽吸功能82和热交换器83从壳体5返回壳体5的气体的循环运动停止,然后将气体 处于通过旁路87从抽吸乐趣82连接到冷却器84的路径仅循环。
