Abstract

PURPOSE:To supply processing liquid automatically and accurately even when the processing quantity of photosensitive material varies by calculating the processing quantity of photosensitive material which is processed within a certain period and judging a normal process or a small-quantity process, and switching the supply automatically according to the judged process. CONSTITUTION:A photosensitive material detecting means 24 detects the passage of the photosensitive material and the processing quantity arithmetic part 19 of a controller 3 calculates the number of processed photosensitive materials or the processing area of the photosensitive material on the basis of the detection signal, so that a processing quantity judging circuit 21 judges the normal process or small- quantity process in the constant period. The processing quantity in the constant period which is found by this processing quantity judging circuit 21 is compared with a reference processing quantity which is set as, for example, a processing quantity per day; when the calculated processing quantity is larger than the set reference processing quantity, a supplying device 2 is driven through a normal supply setting circuit 22 to perform normal supplying operation. When the calculated quantity is smaller than the set processing quantity, on the other hand, small-quantity supply is carried out through a small-quantity supply setting circuit 23.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a photosensitive material processing liquid replenishing device that automatically replenishes processing liquid for processing a photosensitive material.

(Prior Art) As an apparatus for processing a photosensitive material, for example, a photosensitive material such as an exposed film is supplied into the apparatus, and when the photosensitive material passes through a processing tank provided inside the apparatus, it is treated with a processing liquid. There is something to do.

Furthermore, in addition to such a photosensitive material processing apparatus, as an apparatus equipped with an exposure system, for example, an ID card production apparatus or a apparatus described in Japanese Patent Application No. 1983-73010, a photosensitive material processing apparatus can be used. Some methods use a photosensitive material copying method to form a copied image.

By the way, the processing liquid for such a device can be used depending on the usage conditions. Since the capacity is low, it is necessary to replenish the processing liquid. To replenish the processing liquid, the number of processed photosensitive materials or the processed area in a predetermined period is determined, and the processing liquid corresponding to the amount of processing liquid outside the fatigue caused by the processing amount of the photosensitive material is replenished.

Furthermore, since the processing liquid undergoes oxidation fatigue even when the operation of the apparatus is stopped, methods such as determining the downtime and filling the processing liquid to Jff are used.

(Problems to be Solved by the Invention) However, for example, when it comes to photosensitive materials, FI! If the number of days with low ffl continues for more than one week, the amount of processing solution replenishment is done taking into account processing fatigue and fatigue due to the prescribed air oxidation, but when processing small quantities, the amount of replenishment due to air oxidation is smaller than during normal processing. decreases, causing the liquid level to drop due to evaporation.

Therefore, if there is a small amount of photosensitive material in a given period of time, it is necessary to increase the amount of replenishment.For example, the amount of protrusion of the bellows pump may be increased, or the replenishment time may be lengthened by changing the dip switch. However, if this operation is performed manually, it is troublesome and may be forgotten.

The present invention has been made in view of the above, and an object of the present invention is to provide a photosensitive material processing liquid replenishing device that replenishes processing liquid for a photosensitive material accurately and automatically.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a processing liquid replenishing device for automatically replenishing a processing liquid for processing a photosensitive material. The present invention is characterized in that it includes a processing amount calculation section that calculates the processing amount, and a control section that determines that the processing is a small amount processing and replenishes the replenishment amount when the processing amount is less than the set amount for a certain period.

(Function) In this invention, the processing amount calculation section calculates the processing amount of the photosensitive material, and the control section determines that the processing amount is small amount processing if the processing amount obtained by the processing amount calculation section is less than the set amount for a certain period. a small amount I
A1′! I! Replenishment will be carried out.

For this reason, even if a small amount of photosensitive material is processed for a certain period of time, the process is automatically switched to replenishment based on small amount processing, ensuring stable processing of the photosensitive material over a long period of time. can be done.

(Embodiments) Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

A collection rack 6 is provided on the other side of the apparatus main body 4, and a photosensitive material specialist lower is provided on the supply stand 5 side of the apparatus main body 4, which is comprised of the collection rack 6, and on which the processed photosensitive material is collected. A photosensitive material outlet 8 is provided on the collection rack 6 side. A conveying device 10 having a number of conveying rollers 9 arranged in series is disposed between the photosensitive material lower and the photosensitive material outlet 8. As shown in FIG. The conveyance roller 10 is driven at a constant speed by a drive device (not shown), and the stiffness forms a meandering conveyance path 11 for the photosensitive material.

A developing tank 12, a bleach-fixing Ng 13, a washing or stabilizing M14, and a drying section 15 are arranged successively adjacent to each other along this conveying path 11, and these processing tanks contain a predetermined number of developing solutions 16, bleach-fixing solutions 17, Processing liquids such as water washing or stabilizing liquid 18 are stored and each is maintained at a predetermined temperature.

Note that the processing tank may be composed of a developing tank, a bleaching tank, a fixing tank, a washing tank, or a stabilizing tank.

This automatic developing machine is equipped with a replenishing device 2, which will be described below, together with a control device 3, so that processing liquid is automatically replenished.

That is, the replenishing device 2 is equipped with, for example, a bellows pump (not shown), and the developing processing solution is replenished by the operation of the bellows pump. The bellows pump can smoothly supply a small amount of processing liquid, and the amount of replenishment is determined by controlling the operating time based on a control signal manually input from the control device 3.

On the other hand, the control device 3 includes a throughput calculation section 19 and a control section 20, and the control section 20 further comprises a throughput determination circuit 21, a normal replenishment setting circuit 22, and a small replenishment setting circuit 23.

A detection signal is inputted to the processing amount calculation section 19 from a photosensitive material detection means 24 disposed in the photosensitive material lower part of the automatic processor 1 . The photosensitive material detection means 24 is composed of, for example, a microswitch or a photosensor, and the processing amount is determined in the processing amount calculating section 19 based on the detection signal. This amount of processing can be obtained by counting the number of sheets of photosensitive material processed and by determining the processed area of the photosensitive material. When calculating the processing amount from the processing area of the photosensitive material, the width of the photosensitive material is detected by installing multiple similar microswitches in the width direction of the photosensitive material, and the length is calculated from the output time of the detection signal. The processing area of the photosensitive material is calculated from the width and length in the processing amount calculating section 19.

In the replenishment amount judgment circuit 21, based on the information from the processing amount calculation circuit engineer 9, it is compared with the processing amount set for a certain period of time, and if it is north of the standard processing amount, it is the normal processing amount, and in the following cases, the processing amount is It is judged that the amount to be processed is small. The fixed period may be one day or 30.1 weeks, etc., and can be freely selected. A timer of a microcomputer is used to measure the time in the processing amount judgment circuit 21, and the time can be freely measured in about -weeks. - The replenishment set in the normal replenishment setting circuit 22 in the case of normal processing and in the small replenishment setting circuit 23 in the case of small quantity processing is carried out via the replenishment device 2.

Note that the bleach-fix solution 17 is also replenished in the same manner.

Next, the operation of this embodiment will be explained.

The photosensitive material on which the image has been exposed is supplied from the supply stage 5 into the apparatus main body 4 via the photosensitive material lower. This photosensitive material is transferred to a transfer device 1O composed of a conveyance roller 9, and sequentially adjacent developing tanks 12, 7 sheets, a white fixing film 13, a water washing or stabilizing film M1, etc.
4 is transported, dried in the drying section 15, and taken out to the collecting rack 6.

At this time, the photosensitive material detection lower stage 24 detects the passage of the photosensitive material, and based on the detection signal, the processing amount calculation section 19 of the control device 3 calculates the number of sheets of photosensitive material to be processed or the processing area of the photosensitive material. As a result, the processing amount determination circuit 21 determines whether normal processing or small amount processing is performed based on a fixed period of time.

The processing amount for a certain period determined by the processing amount judgment circuit 21 is
For example, the processing amount per day is compared with a set standard processing group 1, and if the processing amount is greater than or equal to the set standard processing group, the replenishment device 2 is driven via the normal replenishment setting circuit 22 to perform normal replenishment. On the other hand, if the processing amount is less than the set processing amount, small amount replenishment is performed via the small amount replenishment setting circuit 23.
