Description

[Detailed Description of the Invention] (Technical Field of the Invention) This invention relates to the structure of a waste liquid tank that collects waste liquid that leaks and falls when the processing liquid in the processing tank is replaced in a photographic film processing machine.

(Technical background of the invention and its problems) Figures 1A and 1B are diagrams for explaining the state of conventional waste liquid recovery. The tank 2 is filled with a processing liquid 3 such as a developer and a fixer, and a processing rack 4 for transporting and processing photographic film is immersed therein. Then, the photographic film is conveyed through the processing liquid 3 in the processing tank 2 by the processing rack 4 and subjected to prescribed processing, but the processing liquid 3 deteriorates over time and needs to be replaced with a new processing liquid. occurs. In such a case, as shown in FIG. 1B, the processing rack 4 is pulled up in the P direction in the figure by a separate drive mechanism, and the processing tank 2 is pulled out to the replacement position in the Q direction in the figure to remove the waste processing liquid. 3 will be discarded and the processing tank 2 will be filled with new processing liquid 3.

When replacing the processing liquid in this way, the processing tank 2 is not placed on the waste liquid tray 1, and the waste liquid accumulated in the groove for conveying photographic film in the processing rack 4 falls as drops 5. 5 is designed to collect in a waste liquid tray 1 located directly below. However, since the processing rack 4 is located high and the falling distance of the waste liquid drops 5 to the waste liquid dish 1 is long, the droplets may splash out of the waste liquid dish 1 or
There was a drawback that the waste liquid remaining on the top remained as a stain, spoiling the aesthetic appearance of the photographic film processing machine.

(Purpose of the invention) This invention was made in view of the above-mentioned circumstances, and it is an object of the present invention to provide a waste liquid tank for a photographic film processing machine that eliminates the splashing of waste liquid drops when replacing the processing liquid and does not impair the aesthetic appearance. The purpose is to

(Summary of the invention) This invention relates to a waste liquid tank for a photographic film processing machine that eliminates the splashing of drops of waste liquid from the photographic film processing liquid so as not to spoil the aesthetic appearance. a tank section for collecting drops of photographic film processing liquid falling from a processing rack attached to the processing tank; The splash plate member is located in a substantially vertical position and rotates from the vertical position to a position slightly tilted upward with respect to the horizontal plane by removing the processing tank when replacing the processing liquid. As a result, drops of the photographic film processing solution falling from the processing rack are collected and stored in the tank portion along the splash plate member.

(Embodiment of the invention) Fig. 2 is a perspective view showing an embodiment of the invention, and Fig. 3 is a side view when a processing tank 20 provided with a recess that engages with the tank portion 10 is loaded.
The tank part 10 for storing waste liquid, which is shaped like a rectangular parallelepiped box with an open top, has a bottom plate 11 and a pair of left and right side plates 12A facing each other and having the same shape and having a protrusion P with one side of a rectangle slightly protruding. and 12B
, the side plate 13 held so as to engage with each protrusion P of the side plates 12A and 12B, and the side plate 1
3 and a wall plate 14 that is disposed opposite to the side plates 12A and 12B and protrudes upwardly. Note that this tank portion 10 may be integrally formed by molding or the like. and,
On both sides of the wall plate 14 are rectangular pieces 15A and 15.
B is installed vertically, and these small pieces 15A and 15B
2, substantially fan-shaped splash plate side plates 16A and 16B are rotatably mounted on cylindrical pins 17A and 17B, respectively. Here, pin 17
The support holes 18A and 18B of the pair of left and right side panels 16A and 16B, which are engaged with the pins 17A and 17B, respectively, have an eccentric shape in the shape of a bead, as shown in FIG. The side plates 16A and 16 are arranged so that the pivot positions of the side plates 16A and 17B can be freely moved between the solid line position and the broken line position, respectively.
B is movable. Two splash plate side plates 16A
and 16B are connected by a splash plate 19 fixed to each lower side to form a splash plate member.

In such a configuration, normally, as shown in FIG. 3, a processing tank 20 provided with a recessed portion that engages with the tank portion 10 is loaded so as to be in contact with the processing tank 20.
The splash plate 19 is flipped upward by the side surface 21 of the processing tank 20 using the pins 17A and 17B as fulcrums. However, the splash plate 19
It stops when it hits the wall plate 14 at 0 and does not fall to the other side. As a result, the splash plate 19 (or the splash plate side plate 1
6A, 16B) become inverted as shown in FIG. 6A in response to the pressing force of the side surface 21 of the processing tank 20, and due to their own weight, the pins 17A and 17B engage with the upper positions of the support holes 18A and 18B, respectively. It turns out. Therefore, the splash plate 19 (or the splash plate side plates 16A, 16B) is pushed down by a length L1 compared to when it is engaged in the lower position, and the space for the splash plate 19 is saved. Can be made smaller.

From such a steady state, when the processing rack 4 is pulled upward to replace the processing liquid 22 and the processing tank 20 is pulled out to the processing liquid exchange position in the direction Q shown in the figure, as shown in FIG. As shown in Figure 6A, the splash plate side plates 16A and 16 including the splash plate 19
Since the center of gravity G of B is on the right side of the pins 17A and 17B where the fulcrum is, the splash plate 19 has R as shown in the figure.
A moment acts in the direction, and the splash plate 19 (or the splash plate side plates 16A, 16B) rotates to a position where it collides with the protrusion P of the tank portion 10 and stops, as shown in FIG. At this time, the angle α that the splash plate 19 makes with the horizontal line is about 30 degrees, and the center of gravity is on the right side in the figure with respect to the point of collision with the protrusion P. Therefore, as shown in FIG. 6B, the pins 17A and 17B will engage with the lower positions of the support holes 18A and 18B, respectively. Therefore, compared to the case where the splash plate 19 is engaged in the upper position, the splash plate 19 protrudes in the direction of the processing rack 4 by a length L2, and the splash plate 19 has an area that receives drops of waste liquid from the processing rack 4 by that amount. can be made wider. The drops 5 of waste liquid leaking from the treatment rack 4 fall onto the upper surface of the splash plate 19 which is tilted and stationary, and the fallen waste liquid is guided to the tank part 10 through the upper surface of the splash plate 19. It collects inside it.

Furthermore, when the processing tank 20 is filled with new processing liquid and is loaded so as to be in contact with the tank section 10 again, the splash plate 19 is inclined at an angle α from the horizontal line, so that the processing tank 20 is It is easily flipped up by the side surface 21 and becomes the loaded state shown in FIG.

Note that the waste liquid that accumulates in the tank section 10 only falls as drops, so if left alone it will evaporate, but a heater is provided in the tank section 10 to actively evaporate it. You can do it like this. In addition, if the amount of processing in the photographic film processing machine is large and the processing liquid has to be replaced frequently, and the amount of waste liquid that accumulates is greater than the amount that evaporates, a liquid level gauge may be provided in the tank section 10. An alarm may be generated when waste liquid exceeding a reference level accumulates in the tank section 10.

Furthermore, an elastic member (for example, a spring) is provided to tilt the side panels 16A and 16B in the R direction,
Power may be applied to rotate the splash plate 19 in the R direction without relying on the weight of the splash plate side plates including the splash plate 19. Furthermore, the structure of the tank part can be modified as long as it is capable of collecting and storing waste liquid, and an opening may be provided in the side surface of the tank part to collect waste liquid from the splash plate.

(Effect of the invention) As described above, according to this invention, the processing
Since the falling distance between the splash plate 19 and the splash plate 19 is short, the droplets are not splashed around, and the droplets are surely collected on the top surface of the splash plate and collected in the tank, and the interior of the tank cannot be seen from the outside and spoils the aesthetics. Not at all. Further, in the above embodiment, the wall plate 14 is used as a stopper for the splash plate 19, so when the splash plate 19 is inverted by the processing tank 20 as shown in FIG. The upper surface faces the wall plate 14 of the tank 10, and if you inadvertently touch the upper surface of the splash plate 19, the splash plate 1
There is no need to get your hands etc. dirty with the waste liquid attached to the tube.
However, the wall plate 14 does not necessarily need to be higher than the other side plates; instead, the wall plate 14 may be of similar size to the side plates 13, and instead the small pieces 15
There are side plates 16A and 16 near A and 15B.
A simple stopper for B may be provided.

In the above embodiment, the case where the processing rack 4 was pulled upward was explained, but the processing rack 4
It goes without saying that the processing tank 2 may be fixed and the processing tank 2 may be pulled downward.
