Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a spray-type ultra-quick processing method in which a processing liquid is sprayed onto a photosensitive material, such as a film or photographic paper, to rapidly perform processing such as development and fixing.

In camera processors, each step from photographing to fixing is performed continuously in a consistent process, and therefore each step is required to be processed quickly and within a certain amount of time.

For this reason, a spray type rapid processing method is used for developing, fixing, etc. in camera processors.

This spray-type ultra-rapid processing involves spraying a certain amount of a processing solution such as a developer heated to a certain temperature onto a photosensitive material to perform development processing and the like.

Figure 1 shows the temperature of the processing solution (developer) when conventional spray-type ultra-rapid processing is performed at room temperature A (approximately 20°C), B (approximately 15°C), and C (approximately 10°C). It is a graph showing changes.

The processing liquid is at a constant temperature t1 at the moment it is injected, but it immediately begins to cool down, drawing a temperature curve according to the room temperature, and the temperature decreases to each room temperature A, B, and C.

The lower the room temperature, the more rapidly the temperature will drop.

In this way, the spray type rapid processing method sprays a small amount of processing liquid onto the photosensitive material to perform development processing, etc., so unlike the conventional method, the processing liquid is simply processed and heated to an appropriate temperature (approximately 30°C to
If the temperature of the processing liquid is maintained at 40° C. and sprayed, the temperature change of the processing liquid attached to the photosensitive material will be significantly affected by the room temperature.

In order to obtain a certain development effect, the integral value of the processing temperature is required to be constant, but as mentioned above, when the room temperature is low, the temperature decreases quickly, and when the room temperature is high, the temperature decreases slowly and relatively high. If the temperature drops to a certain level, processing times such as development must be changed considerably in order to obtain a constant integral value.

In view of the above problems, the present invention has been developed to
The purpose of the present invention is to provide a spray-type ultra-quick treatment method that allows a constant integral value of treatment temperature to be obtained within a constant time, thereby obtaining the same treatment effect just by repeating a constant cycle. It is something to do.

The processing method of the present invention is characterized in that by heating the photosensitive material according to the room temperature, the temperature of the processing liquid attached to the photosensitive material does not drop, thereby making the integral value of the temperature constant. It is something to do.

The temperature at which the photosensitive material is heated is approximately 30° C. to 40° C., but this temperature is adjusted to be higher when the room temperature is low.

A heater is used as the heating means, and the temperature of this heater is always controlled in consideration of the room temperature and the temperature of the photosensitive material.

FIG. 2 is a graph showing the temperature change of the processing liquid according to the method of the present invention.

When the room temperature is low C (approx. 10℃), the temperature of the processing solution is also low C.
Therefore, the temperature of the photosensitive material drops to temperature C at the moment it adheres to the photosensitive material, but since the photosensitive material is heated,
Temperature rises.

After the temperature is rapidly raised to about 40° C., the temperature is lowered by the processing liquid sufficiently sprayed onto the photosensitive material.

When the room temperature is high A (approximately 20°C), the treatment liquid is gradually heated to approximately 30°C after injection, creating a gentle temperature curve, and when the room temperature is intermediate B (approximately 15°C), the above-mentioned It is heated to about 35° C., drawing a temperature curve corresponding to the middle of room temperatures A and C.

As mentioned above, in the present invention, when the room temperature is low, it is rapidly heated to a high processing temperature, and when the room temperature is high, it is heated slowly to a low processing temperature, so the integral of the processing temperature within a certain time The value becomes constant.

As a result, a certain level of development processing is carried out, and the same level of development processing is carried out in a fixed amount of time regardless of the room temperature, so in devices such as camera processors that perform a consistent process from photography to development, This is preferable because the same processing effect can be obtained by simply repeating the same cycle.

Next, the apparatus used in the method of the present invention will be explained with reference to FIG.

The photosensitive material 10 is held or placed on a heater 11,
It is heated from behind by a built-in heating wire 12.

The photosensitive material 10 is sequentially moved in a fixed direction, either continuously or intermittently, and development processing is performed during this period.

The hot wire 12 of the heater 11 is connected to an amplifier 13 so that the current is controlled to adjust the heating temperature.

The amplifier 13 receives output signals from a temperature sensor 14 that detects the temperature of the photosensitive material 10 and a temperature sensor 15 that detects the room temperature, and controls the output current to adjust the temperature of the heater 11. It has become.

Although it is preferable that the room temperature does not change, since a temperature sensor 15 is provided to detect the room temperature, if the room temperature changes, the heater 11 is automatically adjusted accordingly.

A nozzle 16 for spraying a processing liquid is arranged in front of the photosensitive material 10, and is designed to spray the processing liquid for about 1 to 10 seconds.

The photosensitive material 10 is heated according to the room temperature, and a processing liquid is sprayed onto the surface of the photosensitive material 100 from the nozzle 16.

When this processing liquid adheres to the photosensitive material 10, the temperature temporarily drops to room temperature as shown in FIG. 2, but since the photosensitive material 10 is heated by the heater 12, it immediately rises.

This temperature rise varies depending on the room temperature and the temperature of the photosensitive material 10 itself, as shown in FIG.

Such temperature cycles at each room temperature are repeated, and the photosensitive material 10 is continuously developed.

As described above, in the present invention, since the photosensitive material is heated according to the room temperature and subjected to development processing, etc., the integral value of the processing temperature within a certain period of time can be made constant regardless of the room temperature. Accordingly, a certain developing effect can be obtained and the desired purpose can be achieved.
