DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a processing liquid supply apparatus, and more particularly to a photographic printing apparatus in which a developing liquid, a fixing liquid and a stable liquid can be appropriately supplied from a container to a developing processing tank, a fixing processing tank and a stable processing tank. The present invention relates to a technique applied to a developing device.

[0002]

2. Description of the Related Art Exposure printing is performed on an emulsion surface of photographic paper (hereinafter, also referred to as paper), and then sequentially passed through processing tanks containing processing liquids for development, fixing, and stabilization, and then dried. A photographic printing / developing apparatus configured to discharge the image to the outside has been put to practical use.

For example, US Pat. No. 5,307,114
According to the photographic printing / developing apparatus disclosed in the above-mentioned publication, the continuous roll paper contained in the paper magazine in a light-shielded state is cut in advance by a cutter unit into a desired cut size, and then the emulsion surface is turned up. After being conveyed to the exposure baking unit, after exposure baking to a desired size by a film set in the scanner, then conveyed, developed, bleached, after sequentially conveyed in a processing tank containing a processing liquid for washing, Devices configured to dry and discharge to the outside have been proposed.

On the other hand, in the above-described processing tanks, ie, the developing tank, the fixing processing tank, and the stabilizing processing tank, when each processing liquid is processed with a fixed amount of photographic paper, or when the processing liquid evaporates and the concentration becomes low. When it becomes dark, it is configured to dilute with water to maintain a predetermined concentration. More recently, it has become possible to appropriately supply the above-mentioned concentrated solution from a container in which a concentrated solution of a developing solution, a fixing solution, and a stable solution is separately stored to each of the replenishment tanks of the developing tank, the fixing processing tank, and the stable processing tank. The photographic printing / developing apparatus whose operation has been simplified by this has become mainstream.

Since each of the above-mentioned processing solutions also contains a chemical substance which is undesirable for the human body, the concentrated solution is completely sealed in a container. It is desirable to supply automatically to

Therefore, the edge portion is further broken so as to form a circular portion 35a, and the edge portion of the shallow valley portion 64 is also broken. Then, when the hole is further drilled and reaches the deep valley portion 65, a state shown in FIG. 10B is obtained in which a part 353b is left.

According to the piercing member 45 configured as described above, the driving force for piercing the sealing member of the container can be reduced, and a large circular opening is formed after piercing the sealing member. Further, since the broken portion is retracted to the container side, the outflow resistance can be reduced, so that the outflow time can be shortened. Further, since the treatment liquid hardly remains, cleaning for recycling is simplified.

FIG. 11 shows the relationship between the shape of the tested drill body, the drilling force at the time of drilling at high speed and drilling at low speed, and the distance from the blade to the above-mentioned shallow valley 64 and deep valley 65. It is a chart. As shown in this figure, it can be confirmed that according to the perforated body having the shape (g) close to the above shape, the difference between the perforation at high speed and the perforation at low speed is small, and the perforation can be performed with low perforation force. Was.
