Description

Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a drying apparatus for drying a photosensitive material such as photographic paper which has been processed with various processing solutions such as a developing solution. 2. Description of the Related Art Generally, a photographic processing machine transports a photographic paper exposed by an exposure device to a processing tank of a developing processing apparatus and develops the photographic paper with various processing liquids such as a developing solution filled in the processing tank. After performing bleach-fixing, stabilization, and the like, the printing paper is conveyed to a drying processing apparatus, and is dried while being conveyed by a conveyance mechanism of the drying processing apparatus to finish a print. [0003] The drying apparatus is equipped with a photographic paper transport mechanism and a heating and drying means for drying the photographic paper. The heating and drying means is for supplying warm air to the photographic paper transported by the transport mechanism. , A blower provided on the upstream side of the duct, and a heater for heating the air blown by the blower. In the above drying apparatus, air heated to a certain temperature by a heater is supplied to a transport mechanism by a blower, and the photographic paper transported by the transport mechanism is dried by the hot air. I have. [0005] There are many types of photographic paper used in the above-mentioned photographic processing machines, which are different in maker, thickness, material, surface quality, application, and the like. Therefore, when the developed photographic paper is dried at a constant transport speed at a constant drying temperature,
Depending on the type of photographic paper, for example, the material of the photographic paper, the degree of drying differs. However, such problems as sticking of the photosensitive surface of the photographic paper and sticking of the photographic papers in some cases occur. To solve the above problems, a method of changing the transport speed of the photographic paper in the drying processing apparatus can be considered.
If the transport speed of the photographic paper in the drying processing device is reduced, for example, the transport speed of the photographic paper not only in the drying processing device but also in the developing processing device located on the upstream side of the drying processing device must be reduced. In other words, there is a problem that the processing capability of the photo processor is reduced as a whole. The present invention has been developed in view of the above circumstances, and has as its object to provide a drying apparatus capable of performing a drying process at a drying temperature suitable for the type of photosensitive material to be dried. I have. According to a first aspect of the present invention, there is provided a photosensitive material drying processing apparatus in which a photosensitive material is dried by a heating and drying means. The control means has a storage unit for drying temperature data in which a drying temperature is set for each type of photosensitive material, and is heated and dried so as to have a drying temperature corresponding to the type of photosensitive material to be dried. The means is controlled by the control means. The kind of the photosensitive material according to the first aspect is mainly due to the difference in the manufacturer, thickness, material, surface quality, and application. FIG. 1 schematically shows a photographic processing machine equipped with a drying processing apparatus according to the present invention, and is basically a printing material which is an example of a photosensitive material. The printer 1 includes a printer 1 that prints an image on paper P, and a processor 2 that performs processing such as development on the photographic paper P that has been printed.

A transport mechanism 22 for transporting the photographic paper P is mounted. The drying apparatus 2c includes a transport mechanism 3 for transporting the photographic paper P, and a heating and drying unit for drying the photographic paper P transported by the transport mechanism 3 at a predetermined drying temperature. It comprises a duct 4 for supplying warm air to the transport path of the photographic paper P, a blower 5 disposed upstream of the duct 4, and a heater 6 for heating the air blown by the blower 5. The warm air whose temperature is increased by the heater 6 and is introduced into the duct 4 from the blower 5 is supplied to the photographic paper P being conveyed through the duct 4. The photographic processing apparatus described above prints, for example, a frame image of a developed film on the photographic paper P, which is sequentially pulled out from the paper magazines 11a and 11b and cut to a predetermined print size by the cutter 12, by the exposure device 13. Subsequently, the photographic paper P is immersed in various processing liquids such as a developing liquid and a fixing liquid filled in the processing liquid tank 21 of the developing processing apparatus 2a to carry out each processing such as development, bleaching / fixing, and stabilization. After the processing is sequentially performed, the processing liquid adhering to the surface of the photographic paper P is removed by the removing device 2b, and the photographic paper P is further sent to the drying processing device 2c and dried by hot air while being transported by the transport mechanism 3 while being transported by the transport mechanism 3. Subsequently, the print is discharged from the print discharge device 2d. In the embodiment shown in FIG. 2, in the embodiment shown in FIG. 2, a controller 8 composed of a microcomputer is mainly used as control means for controlling the driving of the heater 6 and the like in the drying processing apparatus 2c. On the input / output unit of the controller 8, a monitor 9a for interactively displaying the operation state and various setting states of the photo processor and a keyboard 9b for inputting various information to the controller 8 are provided. Connected. The program of the controller 8 includes:

More specifically, the photographic paper setting mode 82 is called by operating the keys of the keyboard 9b, and the monitor 9a is set.
The screen of the photographic paper setting mode 82 is displayed on the screen of, and the type of the photographic paper P set in each of the paper magazines 11a and 11b is set on the screen. Along with the printing process by the photo processing device, the discriminating function 83 discriminates the paper magazine 11a or 11b used in the printing process, and sets in the photographic paper setting mode 82 based on the discrimination result. The type of the photographic paper P is determined based on the information, the drying temperature corresponding to the type of the photographic paper P is determined from the drying temperature data storage unit 81, and the heater 8 of the heater 6 is controlled by the controller 8 so as to have the drying temperature. The calorific value is controlled.

Is cut out to a predetermined print size by the cutter 12, and an image is printed on the printing paper P by the exposure device 13. The photographic paper P having undergone the image printing process is conveyed to the developing device 2a, where it is subjected to a developing process using various processing liquids, and then adheres to the surface of the photographic paper P by the removing device 2b. After the processing liquid is removed, the drying liquid is sent to the drying processing apparatus 2c, and is dried by the warm air supplied through the duct 4 while being transported by the transport mechanism 3 of the drying processing apparatus 2c. It is ejected and the print is finished. As described above, in accordance with the print processing operation by the photo processing apparatus, the discriminating function 83 causes the paper magazine 11a or 11
