Description

Description: BACKGROUND OF THE INVENTION The present invention relates to a technology for improving the efficiency of a drying section and saving energy in a photosensitive material processing apparatus.

[Conventional technology]

Drying equipment for automatic processing of silver halide photosensitive material is a type that uses an electric heater and a fan to blow hot air onto the photosensitive material to dry it, or a type that simply transports the photosensitive material between stationary heaters to dry it. However, it takes a lot of heat to dry out the photosensitive material in a short time, and it consumes a lot of power. It is necessary to use heat effectively to save energy. It is essential. Heat and heating time contribute to drying. To reduce the heater power, measures have been taken to lengthen the drying time and dry slowly.

[Problems to be solved by the invention]

However, in an automatic developing type photosensitive material processing apparatus, since the photosensitive material moves, a longer drying section must be provided to increase the drying time, and as a result, power for maintaining the long drying section at a high temperature is required. However, there is a disadvantage that the device becomes large and the installation space increases. SUMMARY OF THE INVENTION An object of the present invention is to provide a photosensitive material processing apparatus which can eliminate such disadvantages and can realize energy saving without increasing the size of the machine.

[Means for solving the problem]

Therefore, the drying section is not simply configured to be long, but is divided into two blocks, each of which is an independent drying section through which the photosensitive material actually passes. During drying, both of these two drying sections are energized. When the photosensitive material does not come, the energization of one drying section on the downstream side in the photosensitive material transport direction is stopped, and instead, the heat of the other drying section on the upstream side is sent, We thought that keeping the heat constant would save energy and reduce the time required for the temperature to rise during use.

That is, the object is to develop a photosensitive material processing apparatus having means for developing, drying, and discharging the photosensitive material, a first drying section having a heat source section, and a first drying section having a heat source section in order from the upstream in the transport direction along the photosensitive material transport path. (2) a second drying section, wherein while the first drying section is energized, the residual heat can be sent to the second drying section, and after the photosensitive material has passed through the entrance of the photosensitive material processing apparatus, the second drying section This is achieved by a photosensitive material device characterized by starting the energization of the drying section.

〔Example〕

The drying unit was configured in two blocks in series, one of which was energized and the remaining heat was sent to the other. The drying section is configured to use both of them in time to dry the photosensitive material. During standby, only one of the drying sections is energized and preheated. By actively pre-heating this, it is possible to quickly raise the temperature of the entire drying section to an appropriate state when trying to dry through the photosensitive material after finishing the standby state next time. did.

Next, the configuration of the present invention will be described in detail with reference to the drawings of the embodiments. FIG. 1 is a side sectional view showing the overall configuration of the photosensitive material processing apparatus. The photosensitive material enters through an entrance 1 at the upper left, undergoes development, bleaching, fixing, washing or stabilizing processing, and is discharged to a film basket 4 through a first drying unit 2 and a second drying unit 3. The hot air of the first drying unit 2 passes through the duct 6 and the fan 5
And sent to the second drying unit 3 through the duct 7.

FIG. 2 shows the configuration of the first drying unit 2 and the second drying unit 3.
This configuration means that the heat in the drying section is recycled using a duct and a fan, preventing heat from escaping to the outside, and keeping the entire drying section at a constant temperature independently of the others. is there. In this configuration, the power supply control is performed by turning on the power of the apparatus, turning on the temperature control heaters of the respective processing tanks, and raising the temperature to the specified temperature during the standby period of the first drying unit 2.
And the second drying unit 3 is not energized. Next, when the temperature of each processing tank rises to a prescribed temperature suitable for processing, it is detected that the photosensitive material has entered through the inlet 1, and the second drying unit 3 also starts energizing. The photosensitive material enters from the entrance 1 and the second drying unit 3
It takes several minutes to reach the temperature, and the temperature is raised by the preheating by the first drying unit 2, so that the second drying unit 3 reaches the specified temperature in a short time. When the temperature has reached, the temperature has reached the specified temperature in a sufficient time and the drying is sufficiently performed. More errors,
In the event of a paper jam, if the power supply operation of the fan 5 is continued for a certain period of time even when the operation switch of the photosensitive material processing apparatus is turned off, the temperature of the first drying unit 2 and the second drying unit 3 can be quickly reduced. It is.

〔The invention's effect〕

With this configuration, it is possible to reduce the power consumption during standby without increasing the size of the device and increasing the installation area, and to achieve an energy saving effect that can speed up the temperature rise during actual use. Was.
