    摘要: A sheet heating device having heat insulators for preventing at least one of sheet feeding roller and sheet discharge roller from being overheated. The sheet heating device includes a delivery unit for delivering a piece of sheet, a heating unit for heating the sheet on a delivery path of the sheet, a cover member for covering the heating unit and opening on a feed side and a discharge side of the sheet, respectively, and two pairs of rollers adapted to close respective openings of the cover member. The pair of rollers serve as heat insulators for avoiding overheating to the sheet feeding and discharging rollers. Shutter members are also available for heat insulation. The shutter members also serve to confine hot air within an interior of the heating device.

    摘要: A sheet heating device for heating a developer sheet to fix an output image formed thereon. The sheet heating device includes a guide plate and a cover member to define an internal space therebetween. Within the space, a heater and a fan is provided. The fan generate circulating hot air stream which is directed in a traveling direction of the developer sheet. The hot air has a transversal width substantially the same as a transverse length of the developer sheet.

    摘要: A color copying machine has a sheet heating device for heating a color developer sheet while the sheet is being fed. The sheet heating device includes a sheet feed path along which the sheet is fed, a heater unit spaced from the sheet feed path, and a sheet protective member of an insulating material disposed between the sheet feed path and the heater unit. The sheet protective member has a plurality of holes defined therein for passing radiant heat from the heater unit toward the sheet feed path. The sheet protective member may comprise a mesh screen of intersecting filaments or a punched iron sheet.
