摘要： PURPOSE:To obtain an excellent image even in a high-temperature, high-humidity state by providing a moisture absorbing means which is arranged in the device, a shutter which is provided on a discharge port for media and can be opened and closed, and an opening/closing means which controls the shutter so that the discharge port is closed when the device is not in operation. CONSTITUTION:When the device begins to operate, the shutter 31 is opened inward by an electromagnetic solenoid 31b which operates by the startup of a power source. Developed paper 20 after heat fixation can move to a form receiving tray 42 through the open shutter 31. A heat source 52 is arranged below a moisture absorbing agent 51 and heats up by being powered on to discharge moisture absorbed from the moisture absorbing agent 51 to the outside through the open shutter 31. The shutter 31 is closed unless the device is in operation to shield the inside from the outside air. Consequently, the humidity in the device is lower than the outside humidity and an adhesion state becomes hard to occur in development even in a high-humidity, high-temperature state, so that an excellent visual image is obtained.

摘要： PURPOSE:To prevent parts except a light receiving member from being influenced with heat by receiving infrared light transmitted through a reflecting member in the light cast from a light source by the light receiving member. CONSTITUTION:A reflector 51 is an aluminum mirror in an elliptic shape and a halogen lamp 53 is arranged so that it is positioned on the focal point of the reflector 51. A reflector 52 constituting the reflecting member is an elliptic cold mirror and the halogen lamp 53 is arranged so that it is positioned on the focal point of the reflector 52. A reflector 54 is a flat cold mirror and receives the light reflected by the reflector 51, then it reflects only visible light to cast it to an original. Below the reflector 52, a heat shielding plate 55 constituting the light receiving member is arranged so as not to induce the infrared light transmitted through the reflector 52 to a lens 9, etc., on the downside. Thus, the infrared light transmitted through the reflecting member does not heat other parts, such as a lens, etc., and the heat can be effectively processed.
