摘要:
An apparatus for processing a photographic sensitive material capable of accurately controlling photographic characteristics and processing solutions. If exposures of images recorded on a negative film have been integrated, for a predetermined number of frames a mean exposure is calculated and a result of comparison thereof with a reference exposure is supplied to the film processor. The result of the comparison is used to control the processing performance of the film processor. A density meter measures the densities of an exposed portion and a non-exposed portion of a color paper processed in a processor portion. As physical quantities affecting the photographic characteristics, the throughput of color paper per unit period, temperature, pH, specific gravity and electric conductivity of processing solutions, quantity of replenishment of replenisher to be replenished to the processing solutions and quantity of water to be added to the processing solutions are detected. If the detected density is out of a predetermined ranger the cause of the measured density being out of the predetermined range is estimated in accordance with the detected physical quantities. In accordance with the estimated causer the quantity of the replenisher to be replenished to processing baths is changed in accordance with the estimated cause so as to make the density of the exposed portion and the non-exposed portion to be included in a predetermined range.

The method includes the steps of: for a photosensitive material for photographing, which has been used for photographing and on which an image has been exposed and which has been immersed into and processed by a processing solution for photosensitive materials for photographing at an image forming device, dividing at least one of the image developed on the photosensitive material for photographing and a portion of the photosensitive material for photographing other than the image into a plurality of colors, and measuring a density of each color, and storing a measured density value of each color, and repeating the steps of dividing, measuring and storing; and determining a state of the processing solution for photosensitive materials for photographing of the image forming device on the basis of an average value of the stored density values, which average value is calculated each time a predetermined period of time elapses. Accordingly, the state of the processing solution for photosensitive materials for photographing can be determined without using a control strip or the like, and can be managed easily and appropriately.

A method and an apparatus for adding water to a photosensitive material processor for adding an amount of water corresponding to an amount of evaporation of a processing solution stored in a processing tank of the photosensitive material processor, to the processing tank, so as to keep the concentration of the processing solution constant. Relationships between an ambient condition which is determined by one of an ambient temperature and relative humidity of the photosensitive material processor, an ambient vapor pressure, and an ambient absolute humidity on the one hand, and the amount of evaporation of the processing solution on the other, are determined in advance. The ambient condition is detected, and the amount of water to be added to the processing tank is determined on the basis of the ambient condition detected and the relationships determined, so as to supply the determined amount of water to the processing tank.

According to the present invention, there is disclosed an apparatus for treating a photosensitive material comprising a treating solution tank storing a treating solution for treating the photosensitive material, a replenishing unit for replenishing the solution into the treating solution tank and a water adding unit for adding water into the treating solution tank, in which an overflow sensor is provided to sense an overflow of the treating solution out of the treating solution tank based on the difference in the thermal conductivity of the surrounding environment as observed while the overflow is taking place and while the same is not taking place, and a predetermined amount of the solution is intermittently added by a constant amount to evaluate an entire amount of the solution replenished until it overflows out of the treating solution tank so that a corresponding amount of water may be added by the water adding unit. Therefore, the actual evaporation loss may precisely be compensated with water.

Therefore, the characteristics of the change in the processing solution state appear in the history of change of the exposure condition correction parameter values. In other words, the processing solution can be determined whether or not it is in a preferable state based on the history of change of the correction parameter values.

A feed rack in which a substantially U-shaped film passage is formed, and disposed in a processing tank such that the processing solution level of the processing tank is located below the top surface of a block by a predetermined dimension so as to reduce the area of contact between the processing solution and outside air. The processing tank is equipped with a solution level regulation tank or replenisher tank in which air-isolating member is floated on a contained solution. Between the replenisher tank and the processing tank are provided a transport mechanism for transporting a replenisher from the replenisher tank to the processing tank and a prevention mechanism for preventing the air-isolating member from entering the processing tank.
