[0002]

2. Description of the Related Art In an automatic developing machine, which is a kind of photosensitive material processing apparatus, developing, fixing, and washing processes are sequentially performed by immersing a photosensitive material in each processing liquid while being transported by a transport roller. The processed photosensitive material is discharged outside the machine after being dried by a drying device.

The drying device has a drying box through which the photosensitive material passes, and the drying air is circulated and supplied into the drying box.

That is, an outlet duct and a suction duct are provided between the drying box and the blower, and the end of the outlet duct is connected to an outlet of the blower and a drying air circulation supply inlet of the drying box. The end of the suction side duct is connected to the suction port of the blower and the drying air circulation supply outlet of the drying box. In addition, a heating element is interposed in the middle of the outlet duct, and an air filter is interposed in the middle of the suction duct.

[0005] Thereby, the air blown from the blower is heated by the heating element, and is supplied into the drying box as dry air through the blowing side duct. The drying air used for drying the photosensitive material is returned to the blower via the suction side duct and circulated.

Conventionally, the blow-out duct and the suction-side duct are formed by sheet metal working, and each duct has a connection portion for connecting to a drying box and a blower, and a storage portion for storing a heating element and an air filter. In a part having a complicated shape such as, for example, a heating element, a heating element casing accommodating an air filter, and an air filter casing are separately formed from a plurality of members such as separately manufactured from other parts of each duct. Have been. For example, in the blow-out duct 101 shown in FIGS.
2 and a heating element casing 108, the duct 101 is divided and the upper end of the duct body 102 is connected to the drying air circulation supply inlet 106 of the drying box 104, and the heating element is connected to the lower end of the blowing side duct 102. The duct has been assembled in such a manner that the upper end of the casing 108 is connected and the lower end of the heating element casing 108 is connected to the outlet of a blower (not shown).

According to this, the connecting portions 66, 74, 88, and 94 are integrally provided, and the bent portion is formed. Further, even if the shapes of the ducts 52 and 76 are complicated to integrate the heating element housing section 56 and the filter housing section 80, molding is extremely easy. PA / PPE alloy
A, PPO-M, PPE-M, PPS, ABS, etc., among the blow molding grades, those having flame resistance and having a heat deformation temperature of about 80 ° C. or more are preferable. In particular, if the resin material is a PA / PPE alloy / hollow grade and the ducts 52 and 76 are formed by blow molding using the same, molding becomes easier. In addition, duct 5
2 and 76 are heated by the drying air heated by the ceramic hot air heater 54, and
Blow molding using an A / PPE alloy / hollow grade improves heat resistance and combustion resistance.

Here, the PA / PPE alloy is a polymer alloy of a crystalline resin polyamide (PA) and a non-crystalline resin polyphenylene ether (PPE), and has the characteristics of polyamide and polyphenylene ether, respectively. In other words, PA / PPE alloys and hollow grades suitable for blow molding, ie, blow molding, have excellent quality balance in terms of moldability, heat resistance, etc., and include, for example, Remalloy (trade name of Mitsubishi Yuka Co., Ltd.) For example, BX512 flame-retardant grade can be used.

Further, by using a ceramic heating element, safety at the time of heat generation is improved. In particular, by using the ceramic hot air heater 54,
Safety during heat generation is further improved.

The present invention is not limited to the above embodiment, but can be variously modified. For example, in the outlet duct 52 and the suction duct 76, each connecting portion 6
6, 74, 88, 94, and the heating element housing 5
6. The shape of the air filter housing 80 is not limited to the shape of the above embodiment.
