A laminating apparatus and a laminating method for finely finishing laminate processing without performing edge processing after the laminate processing is performed to a recording medium. A laminate material having a size larger than that of the recording medium is placed to cover the recording medium, bonded with heat and pressure, and a laminate layer protruding from the recording medium is transferred to a means to be transferred to, which is arranged on an opposite plane side to a recording plane of the recording medium. When the means to be transferred to is arranged apart on the opposite plane side to the recording medium, the laminate layer is pulled into the opposite plane side to the recording medium. As a result, an edge of the laminate layer formed on the recording plane of the recording medium becomes fine, matching with an edge of the recording medium.

A developing liquid circulation controlling system includes a circulating pump 61-67 for providing circulation of processing liquid from an upper region of a processing tank 41-47, an auxiliary tank 41a-47a, a circulating passage 51-57, a lower region of the processing tank and then back to the upper region of the processing tank. The circulating pump provides at least two selectable differing circulation amounts. For providing this, the system includes a use condition detecting sensor 10 for detecting at least two different use conditions of the processing tank, and a controller 100, 101 operatively connected with the sensor. The controller sets the circulating pump to a high circulation amount mode when the sensor detects a first use condition and sets the pump to a low circulation amount mode when the sensor detects a second use condition.

System for controlling circulation of developing liquid

A developing apparatus includes a developing tank (2) for developing photosensitive material, an auxiliary tank (3) communicated with the developing tank, a replenishing container (70) communicated with the auxiliary tank and holding therein processing liquid, a replenishing pump (91-94) for feeding the processing liquid from the replenishing container to the auxiliary tank, a replenishing pump operation instructing unit (100B) for activating the replenishing pump in accordance with a condition of the processing tank. The apparatus further includes a detector (91a-94a) for detecting a work amount of the replenishing pump, a determining unit (100B) for determining whether a cumulative value of detected work amount has reached a preset reference work amount or not and a notifying unit for notifying arrival of the cumulative value at the reference work amount in response to the determining unit.

Developing apparatus

A float sensor system for a replenishing tank 70 including an injection nozzle 80 attachable to a liquid feeding nozzle 60 of a replenishing device 70 for replenishing processing liquid to a development processing tank unit. This system includes a float 82 provided to the injection nozzle 80 of a replenishing tank 71-74 and movable between a first position and a second position, and a float detecting sensor 64 mounted to the liquid feeding nozzle 60. When an amount of liquid in the replenishing tank attached to the liquid feeding nozzle 60 exceeds a predetermined value, the float 82 is moved to the first position. When the liquid amount is lower than the predetermined level, the float 82 is moved to the second position. Also, the float detecting sensor 64 outputs a float detection signal when the float 82 is located at this second position.

An automatic photographic developing machine allows a rack to be pushed up only if a feed mechanism of such rack is put under excessive load, and is made of fewer parts and is simple in structure. The rack has a feed mechanism for feeding photosensitive material and is inserted in a treating tank. The rack has an input shaft at its upper portion. The input shaft carries a helical gear in mesh with a worm of a drive shaft. A resilient piece made of synthetic resin is supported on a presser holder slidable in the axial direction of the drive shaft. An end of the resilient member is located opposite the end of the input shaft to prevent the rack from being pushed up. If the force urging the rack upward exceeds the resilience of the resilient piece due to an excessive load applied to the feed mechanism, the resilient piece is resiliently deformed by the input shaft. The rack is thus pushed up, and the helical gear is disengaged from the worm.

A strainer includes a filter which is easily detachable without the possibility of fluid leakage. The strainer has a housing defining a bore and is formed with a fluid inlet and outlet, and an end plate formed with a circular hole and cutouts provided along the edge of the circular hole, opposite to each other. A closure member is rotatably mounted in the bore of the housing and is formed with a passage through which the inlet and the outlet can communicate with each other, and a filter mounting hole. A filter is detachably inserted in the filter mounting hole. It has a flange and a knob formed with a protrusion. The edge of the circular hole is sandwiched between the protrusion and the flange. By turning the knob, the closure member can be turned to a position where it closes both the inlet and outlet. By pulling the knob in this state, the filter can be pulled out of the filter mounting hole for cleaning or replacement.

An automatic developing machine is proposed which is more compact. The treating tank communicates with the sub-tank through a return passage and a supply passage. In the latter passage, a pump is provided to circulate a treating solution through the treating tank and the sub-tank. To the supply passage, a tablet supply unit is connected which supplies tablets containing components for treating photographic materials.

Automatic developing machine for photosensitive materials

An apparatus for full-automatically processing a photosensitive material is provided which requires less installation space, realizes a higher working efficiency based on a high-speed feeding of film and thereby assures less costly processing. The apparatus includes: a film-developing part for developing individual films while feeding each of the films accompanying a leader; a printing part for subjecting a photographic paper to an exposure; a paper-developing part for developing the photographic paper exposed; and a film-sorting mechanism, disposed adjacent a terminating end of the film-developing part, for sorting the films by the kinds thereof.
