2. Description of the Related Art There is an apparatus that performs processing such as bleaching, fixing, bleach-fixing, stabilization, and washing with water to form an image on a photosensitive material. In the above processing, for example, the photosensitive material is immersed in each processing solution while transporting the photosensitive material after exposure, so that the photosensitive material on which an image is formed is swollen, and the processing solution adheres to the surface of the photosensitive material. I have. Therefore, it is necessary to dry the photosensitive material by evaporating the processing liquid adhering to or contained in the photosensitive material and then carry out the photosensitive material. Therefore, a photosensitive material drying unit is generally provided integrally with the photosensitive material processing apparatus.

62840 specification, JP-A-1-18839, 1-118840,
There is an apparatus described in JP-A-1-123233 and JP-A-1-123236. The drying section in these apparatuses is configured to blow hot air onto the photosensitive material after passing through the processing liquid or to irradiate the photosensitive material with infrared rays to evaporate the moisture on the surface or inside the photosensitive material.

口から吸引する構成であり、感光材料表面近傍の含湿空
気を逐次排気することができる。The apparatus described in JP-A-1-123236 discloses a configuration in which air is blown to a photosensitive material from a nozzle provided in the vicinity of a transport roller, and the blown air is suctioned from an intake port provided behind the transport roller. That is, it is possible to sequentially exhaust the humid air near the photosensitive material surface.

気の風速や温度を高めないと、迅速に乾燥を行うことが
できないという問題がある。However, since the intake port is located behind the transport roller, when air near the surface of the photosensitive material is sucked from the intake port, the transport roller becomes an obstacle to air flow and the exhaust resistance is large. Air cannot be exhausted well. Therefore, there is a problem that drying cannot be performed quickly unless the wind speed and temperature of the air blown out from the nozzles are increased.

乾燥しないという問題がある。In addition, the transport roller obstructs air flow, causing air turbulence near the transport roller, and a negative pressure between the transport roller and the nozzle, so that the photosensitive material has a waving phenomenon such as flapping during transport. Occurs and is not properly transported along the transport path. Therefore, there is a problem that the photosensitive material is not deformed or dried uniformly.

気が受ける抵抗は少なく、乱流や負圧が発生しにくく空
気の流通が円滑になる。In other words, the transport roller has air permeability,
When the air near the photosensitive material surface is exhausted by the suction section behind the transport roller, it passes through the transport roller and flows well. In addition, since the transport roller has air permeability, the air receives little resistance during exhaust, and turbulence and negative pressure are less likely to be generated, so that the air flows smoothly.

とができる。Therefore, the moisture-containing air near the surface of the photosensitive material is efficiently exhausted, so that the drying time of the photosensitive material can be shortened. Further, the photosensitive material is properly conveyed without flapping and the like. Etc. can be prevented.

Then, the air reaches the intake hole 81 and is exhausted. Therefore, when the humid air near the surface of the photosensitive material is exhausted from the intake holes 81, the humid air smoothly reaches the intake holes 81, and turbulence and negative pressure are not generated near the transport rollers. Accordingly, it is possible to satisfactorily exhaust the humid air in the vicinity of the photosensitive material.

The coaxial rollers 56a to 56g are formed of stainless steel, plastic resin, or the like. Since a predetermined gap is formed between the coaxial rollers 56a to 56g, the humid air near the surface of the photosensitive material is removed by the coaxial rollers 56a to 56g.

される。The transport roller 56 shown in FIG. 6 has a configuration in which a number of openings 55 are dispersedly formed on a peripheral surface of a hollow roller 59 made of metal such as stainless steel or plastic resin. The humid air near the photosensitive material surface once enters the hollow roller 59 from the opening 55, exits from the opening 55 facing the intake hole 81, and is sucked into the intake hole 81.

たスリット等いかなる形状であってもよい。The shape of the opening 55 formed on the peripheral surface of the hollow roller 59 is not limited to a circular shape as shown, but may be any shape such as a slit along the circumferential direction or the axial direction.
本発明によれば、感光材料搬送ローラに近接して設け
たノズルから感光材料に向けて吹き出した空気を、搬送

く空気の流通が円滑になる。According to the present invention, in a photosensitive material drying apparatus having an air suction unit that sucks and exhausts air blown toward a photosensitive material from a nozzle provided near a photosensitive material transport roller from the rear of the transport roller, Due to this property, the air in the vicinity of the photosensitive material surface passes through the transport roller and flows well when exhausted by the suction section behind the transport roller. In addition, since the transport roller has air permeability, the air receives little resistance during exhaust, and turbulence and negative pressure are less likely to be generated, so that the air flows smoothly.
したがって、感光材料表面近傍の含湿空気は効率良く
排気されるので、感光材料乾燥時間を短縮することがで
き、更に、感光材料はバタツキ等が起こらず適正に搬送

とができる。Therefore, the moisture-containing air near the surface of the photosensitive material is efficiently exhausted, so that the drying time of the photosensitive material can be shortened. Further, the photosensitive material is properly conveyed without flapping and the like. Etc. can be prevented.
