Abstract
A drying apparatus includes: a rotatable belt which has an outer surface and an inner surface, the outer surface contacts a sheet; a blowing mechanism which blows hot air on the sheet at a side of the outer surface; and a heating unit which includes a heating element and a contact surface which is disposed in contact with the inner surface. A plurality of rollers are arranged in a direction in which the sheet travels. The rollers are pressed against the outer surface of the belt with the travelling sheet being held between the rollers and the outer surface of the belt.
Claims19
An apparatus for drying a sheet, comprising:
- a rotatable belt which has an outer surface and an inner surface, a part of the outer surface being in contact with the sheet;
- a plurality of rollers arranged in a direction in which the sheet travels, the rollers including a first roller and a second roller which are adjacent to each other, the rollers being pressed against the outer surface with the travelling sheet being held between the rollers and the outer surface;
- a blowing mechanism which blows hot air on the sheet from between the first roller and the second roller;
- and
- a heating unit which includes a heating element and a contact surface which is disposed in contact with the inner surface,
- wherein the first roller is disposed in an upstream of the second roller in the direction and the first roller is pressed against the sheet with urging force smaller than that of the second roller.
An apparatus for drying a sheet, comprising:
- a conveying unit having a plurality of rollers arranged in a direction in which the sheet travels, the rollers including a first roller and a second roller;
- and
- a heating unit configured to heat the sheet at a position between the first roller and the second roller,
- wherein the first roller is disposed in an upstream of the second roller in the direction and the first roller is pressed against the sheet with urging force smaller than that of the second roller.
