DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used in a photosensitive material processing apparatus in which photosensitive material is sequentially conveyed to a processing tank to which a processing solution filled in a cartridge tank is supplied and processed.
The present invention relates to a processing liquid supply structure of a photosensitive material processing apparatus for supplying a processing liquid to the processing tank.

[0002]

2. Description of the Related Art For example, in a photosensitive material processing apparatus such as an automatic developing machine for processing a photosensitive material such as an X-ray film, a mother liquor stored in a developing tank and a fixing tank at the time when the photosensitive material is first processed. Is made by mixing and diluting the stock solution of mother liquor filled in the cartridge tank and supplying it to each tank. The replenisher replenished to the developing tank and the fixing tank after the processing of the photosensitive material is started is made by mixing and diluting the replenisher stock solution filled in the cartridge tank. The processing solution stored in the cartridge tank includes a stock solution of the mother liquor and a stock solution for replenishment. The cartridge tank is to be loaded into a filling tank of the liquid receiving tray.

In some cases, the stock solution cartridge tank for replenishment is partitioned so that a plurality of types of stock solution can be separately filled, and the opening of each tank is closed by a stopper. On the other hand, there is also a liquid receiving tray in which a partition wall is formed and partitioned into a plurality of filling tanks. Each filling tank is provided with a projection, and when the cartridge tank is turned upside down and a plug is loaded in correspondence with the projection, the projection breaks through the stopper and the stock solution in the cartridge tank flows out to the filling tank. (Chicken feeder structure). The filling tank communicates with each stock tank via a pipe. For this reason, the liquid level of the stock replenisher in the filling tank of the liquid receiving tray and the stock replenisher in the stock tank are always matched by the atmospheric pressure. Therefore, as the stock replenisher is supplied from the stock tank to the processing tank, the stock replenisher is gradually sent from the filling tank to the stock tank via the pipe.

[0004]

However, in the above-mentioned conventional structure, immediately after the stopper of the cartridge tank is pierced by the projection, the stock solution in the cartridge tank flows out vigorously. For this reason, the replenisher stock may jump at the bottom of the filling tank and leak from the filling tank. Due to this leakage, different processing liquids are mixed (so-called contamination), and if a drop of the replenishing stock solution adheres to the liquid receiving tray or the cartridge tank and is exposed to the air, it remains as a white adhered substance and causes contamination. .

[0005] For this reason, it is conceivable to reduce the opening area of the mouth of the cartridge tank to make the flow of the replenishing stock solution gentle. However, if the opening area is made small, the replenishing stock solution becomes difficult to flow, which is not preferable.

In view of the above facts, the present invention reduces the momentum of the processing liquid flowing out of the cartridge tank into the filling tank without reducing the flow rate of the processing liquid flowing out of the cartridge tank, and removes dirt caused by splashing and the like. It is an object of the present invention to provide a processing solution supply structure for a photosensitive material processing apparatus which can prevent the processing solution from being prevented.

[0007]

According to a first aspect of the present invention, there is provided a liquid receiving tray for loading a cartridge tank filled with a processing liquid to be supplied to a processing tank, and a central portion near the bottom of the filling tank of the liquid receiving plate. A perforated portion for opening an inlet of a cartridge tank in which a processing liquid is stored, and a flow path restriction provided around the perforated part in the filling tank and for restricting a flow path of the processing liquid flowing out of the cartridge tank. Components,
have.

According to a second aspect of the present invention, there is provided a liquid receiving tray for loading a cartridge tank filled with a processing liquid to be supplied to a processing tank, and a processing liquid provided near the center of the bottom of the filling tank of the liquid receiving tray. A perforated portion for opening an inlet of the stored cartridge tank; and a three-dimensional mesh member having a three-dimensional and mesh structure laid on a bottom portion around the perforated portion in the filling tank and for restricting a flow path of the processing liquid. doing.

[0009]

According to the first aspect of the present invention, the processing liquid flowing from the cartridge tank to the filling tank of the liquid receiving tray is reduced in flow force of the processing liquid by the flow path restricting member, and the flow of the processing liquid is reduced. A spiral rotational force is applied, so that it is possible to prevent contamination of the wall surface of the liquid receiving tray, the cartridge, and the like caused by the rebound of the processing liquid. Further, the processing liquid does not leak from the liquid receiving tray and mix with other processing liquids.

According to the second aspect of the present invention, the three-dimensional mesh member is laid at the bottom of the stock tank. Since the three-dimensional mesh member has a plurality of continuous pores, the processing liquid flowing from the cartridge tank into the filling tank of the liquid receiving tray permeates into the plurality of pores. Here, since the momentum of the flow of the processing liquid is buffered, it is possible to prevent the wall surface of the liquid receiving tray, the cartridge, and the like, which are caused by the processing liquid jumping up.

35 are provided.

As shown in FIG. 5, the liquid receiving tray 13
5 is fixed with screws 140 to a mounting bracket 138 fixed to the side wall of the cartridge receiver 134 via the flange portion 136A. The liquid receiving tray 135 corresponding to the cartridge 100 is provided with three filling tanks 136. At substantially the center of the bottom 136B of the filling tank 136, a projection 142 as a perforated portion is provided. As shown in FIGS. 6 (A), 6 (B) and 7, the projection 142 is configured by standing four plate members 142A that are substantially L-shaped in plan view. . Further, the protrusion 142 is disposed so that a substantially cross-shaped groove is formed in plan view. As shown in FIG. 5, the plate 142A gradually expands from the middle in the height direction to the lower end, and the upper ends are cut linearly so as to be in the same plane. Note that the protrusion 142 is formed on the bottom 13.
6B may be fixed or placed.

The filling tank 136 accommodates a first shielding plate 200 and a second shielding plate 202 as shielding members.

As shown in FIGS. 6 and 9, the first shielding plate 200 has a rectangular flat base plate 204, a through hole 206 is provided at the center thereof,
2 for penetration. The four corners of the base plate 204 are cut in an arc shape to prevent interference with the corners of the inner wall of the filling tank 136, and facilitate insertion into the filling tank 136.

From both sides of the base plate 204, ribs 208 having the same shape are provided upright in directions opposite to each other. The ribs 208 are erected in two rows corresponding to the four corners of the base plate 204. The ribs 208A forming the outer race (see the dashed line L in FIGS. 6 and 9) have a discontinuous arc shape as a whole, and have gaps 210 at two places. On the other hand, the ribs 208B forming the inner ring (see the dashed line M in FIGS. 6 and 9) have a discontinuous arc shape as a whole, and have gaps 212 at three places.
The ribs 208A, 208B of the outer ring and the inner ring have the same arc centers, but the gaps 210, 212 do not lie on the same radial line so that the ribs 208A,

Next, the replenishment of the replenisher will be described. The level of the developing solution is detected by a level sensor (not shown) provided in the developing tank 14 according to the processing amount of the film F, that is, according to the area of the film F detected by the insertion detecting sensor 80, and according to the information. Thus, the developing tank 14 is replenished with the developing replenisher. This replenishment is performed by bellows pump 6
The replenishing stock solution and water are supplied to the first mixing tank 58 by the operations of 4A, 64B, 64C and 68A, and
Thus, these liquids are supplied to the circulation pipe 71 while being mixed. Therefore, in the developing tank 14, the occurrence of unevenness in the developer during the replenishment of the developer replenisher is prevented.

The level of the fixing liquid is detected by the level sensor (not shown) provided in the fixing tank 16 in accordance with the processing amount of the film F, that is, in accordance with the area of the film F detected by the insertion detecting sensor 80. The fixing tank 16 is replenished with the fixing replenisher in accordance with the information. This replenishment
The replenishing stock solution and water are supplied to the second mixing tank 60 by the operation of the bellows pumps 64 </ b> D and 68 </ b> B, and further, these solutions are supplied to the circulation line 75 through the line 74 while being mixed. Therefore, in the fixing tank 16, the occurrence of unevenness of the fixing solution when the fixing replenisher is replenished is prevented.

By supplying the replenisher stock solutions A, B, C and the replenisher stock solution to the first mixing tank 58 and the second mixing tank 60, these solutions in the stock tanks 50A, 50B, 50C, and 50D are supplied in predetermined amounts. When it becomes below, it is detected by the liquid level sensor 52 and the cartridge 100, 1
20 will be replaced.

The exchange of the cartridges 100 and 120 is performed as follows. By rotating the locking member 158 positioned above the liquid supply unit 130, the locking member 158 is disengaged from the locking projection (not shown), and the liquid supply unit 130 can swing. It is swung from the closed state to the open state by the gas damper that does not. This swing is smoothly performed with the speed controlled by the gas damper. The swing of the liquid supply unit 130 is stopped by the gas damper when it advances 15 ° from the closed state, and is stopped by the cartridge 10.
0, 120 can be taken in and out. In this state, the used cartridges 100 and 120 and the new cartridge 1
00 and 120 are exchanged, and thereafter, the outer plate 132 of the liquid supply unit 130 is pressed to swing the liquid supply unit 130 in a direction opposite to the above, so that the locking member 158 and the locking protrusion (not shown) What is necessary is just to make it engage. Thus, the cartridges 100, 12
The exchange of zeros takes place quickly.

When the cartridges 100 and 120 are replaced, the cartridges 100 and 120 are turned upside down so that the injection ports 108, 110, 112 and 122 are directed downward to correspond to the projections 142 of the filling tank 136. In this state, when the cartridges 100, 120 are pushed in, the packings 114, 124 with the inlets 108, 110, 112, 122 attached thereto come off and the cartridges 100, 12
The replenisher stock in 0 flows out. At this time, the replenisher is guided to the fins 214 provided on the first shielding plate 200, and a spiral rotational force is applied to the replenisher, so that air is smoothly sucked into the cartridges 100 and 120. Therefore, the replenisher stock solution flows out smoothly.

On the other hand, the replenisher stock flowed out of the cartridges 100 and 120 is supplied to the ribs 2 of the first shielding plate 200.
08 restricts the flow path. The limited replenisher stock is
Since the gas slowly flows through the gaps 210 and 212, the flow velocity decreases. For this reason, the cartridges 100, 120
The replenishing stock solution which has flowed vigorously from the container does not wrinkle or foam, and the filling tank 136 and the liquid receiving tray 1
The wall surface 35 and the cartridges 100, 120, etc. are not stained.

In this embodiment, the first shielding plate 200
And the base plates 204 and 216 of the second shielding plate 202
Since it has the role of an eaves, the replenishing stock solution jumps up at the bottom 136B of the filling tank 136 and does not stain the wall surface of the liquid receiving tray 135 and the cartridges 100, 120, etc., and also jumps out of the filling tank 136. Disappears.

Next, the mounting position of the liquid supply unit 130 is changed as follows, for example. The cover 156 is removed, the locking member 158 is rotated to release the engagement with the locking projection (not shown), the liquid supply unit 130 is swung to the open position, and the cartridges 100 and 120 are pulled out of the cartridge receiver 134. . In this state, by pulling up the liquid supply unit 130, the engagement between the shaft member 152 and the leg 148 is released, and the gas damper is removed from the automatic developing device 10.

On the other hand, the cover (not shown) on the side opposite to the side on which the liquid supply unit 130 is attached is removed. The liquid supply unit 130 is attached to the opposite side via the shaft member 152 and the gas damper, and the cartridges 100 and 120 are inserted into the cartridge receiver 134. Thereafter, the liquid supply unit 130 is closed by closing, and the cover 156 is attached below the liquid supply unit 130. Then, the cover (not shown) attached to the opposite side is attached to the side to which the liquid supply unit 130 was attached. Thus, the mounting position of the liquid supply unit 130 is changed.

In this embodiment, the first and second shielding members 200 and 202 are provided in the filling tank 136. However, as shown in FIG. A buffer member 221 as a three-dimensional mesh member may be provided. The cushioning member 221 can reduce the momentum of the replenishing stock solution flowing out of the cartridges 100 and 120 by the continuous pores, and can prevent the wall surface of the liquid receiving plate, the cartridge, and the like, which are caused by splashing or the like, from being stained.
