BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a processing liquid tank having a liquid level detecting float in a photographic light-sensitive material developing machine.

[0002]

2. Description of the Related Art In general, each processing liquid tank provided in a photographic light-sensitive material developing machine has a liquid surface position determined for each tank. Conventionally, when water falls below a predetermined position, water is replenished while the tank overflows or the mark plate is viewed from the gap between the rack and the tank.

[0003]

However, with the recent development of a compact photographic material developing machine, the liquid level of the processing liquid tank has become invisible. (Of course, the overflow and the position of the sign board become invisible.)
When the capacity of the tank is reduced, a cover for preventing evaporation of the processing liquid is provided, so that the level of the liquid surface cannot be further visually checked. For this reason, it has become impossible to determine which tank has a low liquid level and which tank needs to be refilled.

The present invention has been developed in view of the above-mentioned problems, and a purpose thereof is to provide a photographic light-sensitive material in which anyone can easily visually judge the liquid level of each tank. An object of the present invention is to provide a processing liquid tank with a liquid level detection float in a developing machine.

[0005]

Therefore, the present invention has the following configuration in order to achieve the above object effectively. That is, a through hole is formed in the cover of the processing liquid tank in the photographic photosensitive material developing machine , and near the through hole,

[0007]

According to the processing liquid tank with the liquid level detection float in the photographic light-sensitive material developing machine having the former configuration, the liquid filled in the processing liquid tank by a predetermined amount is reduced, so that the indicator rod is also lowered together with the float, The pointer of the indicator stick that protrudes from the processing liquid tank indicates downward from a predetermined position on the liquid level display plate, and by looking at this indicated portion, the amount of decrease from the specified liquid level position can be easily confirmed visually. be able to.

Further, according to the processing liquid tank with the liquid level detection float in the photographic light-sensitive material developing machine having the latter configuration, when the processing liquid in each tank is in a specified amount, the rod material protruding from the through hole of the tank cover is formed. If it is arranged where the marked mark is located from the tank cover, as the processing liquid in the processing liquid tank decreases, the rod also descends along with the float. The mark position of the protruding bar also drops, and the liquid level drop from the specified liquid level position
It can be confirmed by visual inspection. Further, even when the rehydration to reduced tank of the liquid can be confirmed visually that could rehydration to a specified position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 and 2 are cross-sectional views of a main part of an embodiment according to the present invention. Numeral 1 denotes a processing liquid tank provided in a photographic material developing machine (not shown), in which a photographic film is developed. These are so-called sub-tanks which are connected to the tanks, respectively.
D), bleaching solution (BL), fixing solution (FIX), and stabilizing solution (STB). Reference numeral 2 denotes a cover that covers an upper opening of the tank 1. Outside the cover 2, a liquid level display plate 3 is provided upright. On the liquid level display plate 3, a scale indicating the prescribed liquid level position and the amount of increase or decrease of the liquid is displayed. Thermal bar 4 continuously to the liquid level display plate 3 are suspended as mow immersion in the liquid. The heat-sensitive bar 4 also functions as a guide bar for the float 5, and the float 5 is loosely fitted to the heat-sensitive bar 4 so as to be vertically movable. A through hole 6 is formed in the cover 2 of the processing liquid tank 1 in the vicinity of the liquid level display plate 3, and an upper portion of the indicator rod 7 erected on the float 5 is connected to the through hole 6. It is designed to protrude outward. An indicator 7a is provided at the upper end of the indicator rod 7 to indicate the scale of the liquid level indicator 3. 8 is an overflow pipe.

In the processing liquid tank with a liquid level detection float in the photographic light-sensitive material developing machine having the above-described configuration, the amount of the liquid filled in the processing liquid tank 1 by a predetermined amount is reduced, so that the float 5 is formed. The indicator rod 7 descends due to the drop of the float 5 accompanying the liquid level drop.
Thus, the indicator rod 7 protruding from the processing liquid tank 1
Of the liquid level indicator 3 indicates a level lower than the scale on which the specified liquid level is displayed, and if the indicated portion is viewed, the amount of decrease from the specified scale to the specified liquid level is determined. Can be easily confirmed visually. In addition, if the shortage is displayed on the scale indicated below the specified liquid level, only the displayed shortage need be refilled into the processing liquid tank 1.

Although the heat-sensitive bar 4 is used as a guide bar for the float 5 here, when the heat-sensitive bar 4 is not used, a guide bar can be separately provided. Further, if a pipe is inserted into the through hole 6 of the cover 2 and the indicator rod 7 is loosely fitted to the pipe so as to be vertically movable, there is no need to provide a bar for guiding the float 5. Of course, as long as the float 5 does not swing so much and the indicating section 7a stably indicates the scale of the liquid level display plate 3, there is no need to provide the guide tube or the guide bar.

FIGS. 3 and 4 show the main parts of another embodiment. The description of the same components as those in the above embodiment is omitted. In this embodiment, a rod material 9 corresponding to the indicator rod 7 is vertically erected from the upper part of the float 5 along the heat-sensitive rod 4 and is formed in the tank cover 2 together with the tip of the heat-sensitive rod 4. Projecting from the through hole 10 formed. In the vicinity of the tip of the bar 9 protruding outside the tank, a band-shaped mark 11 is attached with a predetermined width. The mark 1 may be colored in a predetermined color, may be a line drawn at a predetermined interval, or any other mark as a mark. A cap 12 is mounted on the tip of the bar 9.

In a processing liquid tank with a liquid level detection float in a photographic light-sensitive material developing machine having the above-described structure, a rod protruding from a through-hole 10 of a tank cover when a predetermined amount of processing liquid is in the tank. The mark 11 attached to the material 9
If the position is determined from the tank cover 2 (for example, the lower end of the mark 11 is one point from the upper end of the through hole 10).
It is set that the state of protruding about mm is the normal liquid level state. ), The processing liquid tank 1
The float 5 descends due to the decrease of the liquid filled in the inside by a predetermined amount, and the rod 9 also descends due to the drop of the float 5 accompanying the liquid level drop. Reference numeral 11 moves downward from a predetermined position (regular position), and the amount of decrease in the liquid level from the specified liquid level position can be visually confirmed. In addition, even when water is refilled in the lowered tank, it can be visually confirmed that the water has been replenished to the specified position.

[0014]

[Effects of the Invention] As described above, in the present invention, the reduction of the liquid in the processing liquid tank can be clearly seen from the outside, and the liquid in each processing liquid tank mounted on the photographic material developing machine can be reduced. Then, it is easy to determine which tank needs to be replenished with how much liquid. Also, when replenishing the tank with a shortage of the processing liquid, the position of the liquid level display plate indicated by the pointer portion provided on the indicator rod and the position of the mark of the rod are visually observed.
It can be easily checked whether or not the prescribed amount of the liquid has been replenished.
