Abstract
In a dry air blowing plate, rows of dry air outlets are arranged at given intervals in a transport direction of a photosensitive material. The interval between the dry air outlets within the row is narrower in a front zone of the dry air blowing plate that is close to a dry air inlet, whereas the interval is wider in a rear zone of the dry air blowing plate that is away from the dry air inlet. In the front zone, the velocity of dry air is lower but the aperture rate per unit area is larger. On the other hand, in the rear zone, the velocity of dry air is higher but the aperture rate is smaller. As a result, the volume of blown dry air is almost the same throughout an external surface of the dry air blowing plate, so the dry air is evenly blown to a surface of a photosensitive material.
Claims10
A drying device for drying a recording medium comprising:
- a blower mechanism for generating dry air and sending it out;
- a duct disposed along a transport path of said recording medium and supplied with the dry air from said blower mechanism, said duct comprising a dry air blowing member on a side facing to said transport path;
- a plural number of air outlets formed through said dry air blowing member, to blow the dry air to said recording medium through said air outlets, wherein said air outlets are formed at a smaller aperture rate in a zone where pressure of the dry air on inner surface of said dry air blowing member is larger, said aperture rate being an area rate of apertures of said air outlets per unit area of said dry air blowing member;
- and
- a conveyer mechanism for conveying said recording medium along said transport path, said conveyer mechanism being placed across said transport path from said dry air blowing member, wherein said recording medium is held on said conveyer mechanism by virtue of the dry air blown from said air outlets to said recording medium.
