Description

Photographic processor

The application is U.S. Patent application No.08/839,282 part continuation application, and this application is submitted on April 17th, 1997 by David L.Patton and John.H.Rosenburgh, and name is called " processing instrument of taking pictures ".

The present invention relates to photographic art, more particularly, relate to method and the instrument of handling photosensitive material.

The processing of photosensitive material will be passed through series of steps, and photosensitive material will be had an effect with multiple different treating fluid in this process.Typically, in photographic processor, photosensitive material will pass through developer solution, bleaching liquid, the processing of stop bath and cleaning fluid successively.Then, photosensitive material also will be through oven dry before sending from photographic processor.In each step of above-mentioned steps, photosensitive material all will be through a kind of processing for the treatment of fluid, wherein crucial is the temperature for the treatment of fluid to be controlled in the setup parameter scope, and make the treating fluid tactility luminescent material surface of cleaning, so that suitable chemical reaction takes place between treating fluid and the photosensitive material.In the processing instrument of prior art, the temperature for the treatment of fluid is kept with well heater, and well heater is heated to set point of temperature with treating fluid, and remains in a certain range of tolerable variance of set point of temperature by the temperature of the temperature controller on it with treating fluid.In the processor of prior art, the treating fluid of the photosensitive emulsion surface by stirring contiguous photosensitive material acts on this surface the treating fluid of cleaning.For this reason, the schemes such as treating fluid that can adopt roller, scraper plate or impact to contact with photosensitive material.To handle the required time of photosensitive material in order shortening, can to change processing parameter.Comprising the concentration for the treatment of fluid itself and composition with for treating fluid being acted on the intensity that photosensitive material stirs and the temperature for the treatment of fluid.

The composition that changes treating fluid is difficulty relatively, and this is because most of photographic processors must successfully be handled the photosensitive material that several different manufacturers are produced, and obtains very reliably and result repeatably.The change for the treatment of fluid composition may bring remarkable influence to the product of different manufacturers.

The use HI high impact is stirred, as United States Patent (USP) 5,270,762,5,355,190 and 5,398, disclosed such in 094, can shorten every kind of processing time that treating fluid is required, but can only reach a certain limit, because required chemical reaction is subjected to the restriction of the rate of diffusion for the treatment of fluid in the development emulsion gelatin of photosensitive material.In case employed stirring means can be to a certain extent the treating fluid of cleaning is acted on the photosensitive material surface, if so also if possible, it is just very difficult to make further progress aspect further stirring.

A kind of effective ways in processing time of shorten taking a picture be improve photosensitive material the temperature for the treatment of fluid of process.But the temperature that improves treating fluid can cause chemical reaction velocity to be accelerated.Oxidation may take place in the solution that improves problem that the treating fluid temperature brings and be after treatment, and can decompose with a faster speed usually.In addition, higher temperature has been accelerated the evaporation rate for the treatment of fluid.And then, when using higher temperature, must take more care to treating fluid, burnt or be subjected to prevent the operator because higher temperature causes the infringement of the chemical evapn of degassing generation.And, because equipment uses the increase of the temperature difference between neutralizing when shutting down, make the wearing and tearing aggravation of treatment facility.All above-mentioned factors all need to increase the use spending of equipment.

Speed up processing, the way of photosensitive material being carried out preheating before sending into processing instrument have been proposed to be in the prior art.This method is in efficient, and all there is small raising treating fluid utilization factor and reduction in processing time aspect, and its negative effect is also to have brought aforesaid by the heat that photosensitive material added after the preheating owing to improve the residual problem that the treating fluid temperature is produced.Another problem of pre-this method of photothermographical material is that the temperature of all layers of photosensitive material photosensitive emulsion is all identical.Along with the diffusion for the treatment of fluid in the photosensitive emulsion different layers, the degree of chemical reaction velocity is the same at the bottom of top layer and close foil paper.

A target of the present invention is to overcome the problems referred to above that processing instrument runs into, and specifically be by improving selectively after immersing treating fluid at photosensitive material or reduce its method of temperature, and the temperature for the treatment of fluid integral body does not raise.Above-mentioned target be by the treating fluid of cleaning with zone that photosensitive material surface fully contact in, directly heat or cool off on the film one very the way of zonule realize.

Spot heating that photosensitive material carries out when penetrating substrate or cooling have formed thermograde in sensitive emulsion layer.Formation temperature gradient in the sensitive emulsion layer.Initial when handling the liquid phase effect when the different part of the temperature in the sensitive emulsion layer, its temperature is different and different reactions takes place.This thermograde that is produced by instrument of the present invention gives the sensitive film deviser with great scope of land more, allows them can use various photaesthesia X-ray emulsion Xs.At present, the photosensitive emulsion slower with the treating fluid reaction must be coated with near the photosensitive material surface, and the rapid reaction layer then is coated with near foil paper.This scheme can be not consistent with the best coating position of each sensitive emulsion layer, thereby can not obtain best coating prisoner's light effect and interaction and the image definition between each coating.This scheme the long and is normally reached a kind of compromise, thereby causes the prolongation in processing time, the increasing of required concentration of treatment, the perhaps problems such as insufficient utilization for the treatment of fluid.

The invention provides a kind of photographic processor and corresponding method that is used for developing photosensitive material.This instrument comprises: a treatment pond is used for the treating fluid that splendid attire is handled above-mentioned photosensitive material; One cover conveyer is used for above-mentioned photosensitive material being sent into treating fluid and therefrom sending after handling; One cover heating and/or cooling device is used to pass photosensitive material and produces thermograde.
