Developer is supplied to a first spray pipe disposed in a developing bath. The inside of the developing bath is provided with a heater. A liquid-flow generating unit comprises a liquid-flow generating head and a branch duct, which is connected to a branch pipe of the first spray pipe via a rubber hose. A part of the developer flowing in the first spray pipe is forwarded to the liquid-flow generating head. By a gap-forming ring, a gap is secured between an outer surface of the heater and an inner surface of the liquid-flow generating head so that the developer uniformly flows along the outer surface of the heater in a longitudinal direction thereof. A heater cover is attached to the liquid-flow generating head. An inner surface of the heater cover inclines in the longitudinal direction of the heater.

Photosensitive material processor

A photosensitive material processing device for processing a photosensitive material with a processing liquid while conveying the photosensitive material by a roller pair. A driving device for providing a rotation drive to the roller pair. A drive controlling device that gradually raises voltage of the electric power at the time of starting the rotation drive of the roller pair.

Automatic developing device, roller washing method, photosensitive material processing device, and preparation method for processing liquid

A roller washing method for a photosensitive material processing device. The processing device processes a photosensitive material with a processing liquid while conveying the photosensitive material with a conveying roller. An idle roller is disposed in contact with a circumferential surface of the conveying roller. The circumferential surface of the conveying roller is washed by rotating the conveying roller while supplying washing water to an area where the conveying roller and the idle roller contact each other.

An intermediate guide member is provided attachable and removable between a head portion and a supporting frame of a stocker for printing plates. A number of intermediate guide members is an element to set a time of starting downward movement of hooks supporting a leading end of a printing plate. Three conditions in accordance with lengths of non-detection times are set for detecting the printing plate to judge authenticity of the detection. When the hooks reach vicinities of stoppers provided at supporting bars of a reversal unit, the hooks swing, are pulled-in from above the slope, and transfer the printing plate to the stoppers. Thereafter, by rotating the supporting bars and the stoppers integrally around a shaft, the printing plate is pivoted over toward a back plate, and a lower end of the printing plate is transferred from the stoppers to a receiving plate without damaging the printing plate.

Printing plate stacking device and method of judging authenticity of sheet member detecting state

The present invention provides a photosensitive material processing apparatus in which a photosensitive material is processed with a processing solution. Reliable liquid displacement in the vicinity of the surface of a photosensitive material, and uniform temperature adjustment can be performed. Also, damage or a transport deficiency, caused by a corner of the material coming into a through hole when a conveyance path of the photosensitive material is formed can be prevented. When pre-washing processing is carried out prior to development processing using a developer, processing unevenness in which an overcoat layer partially remains can be prevented. An operation of mounting and removing conveyance rollers disposed in a pair is facilitated and a proper nipping force can be imparted between a conveyance roller pair. Mounting of a replenisher case filled with a replenisher is facilitated and a replenisher is kept from remaining in piping or in a replenisher case.

Photosensitive material processing apparatus

A printing plate processing apparatus provides a step in which a printing plate which has undergone image exposure is processed by being immersed in a developing solution, and the printing plate is delivered while the developing solution is being squeezed out from the printing plate by a conveying roller pair which is partially immersed in the developing solution. A stoppage time of the apparatus is measured, and the conveying roller pair is driven to rotate for an amount of time set in accordance with a measured result of the stoppage time when operation of the apparatus is started, thereby allowing the conveying rollers to be cleaned. A concentration of carbon dioxide in an environment in which the apparatus is installed is detected, and based on the detected result and the measured result of the apparatus stoppage time, the driving time of the conveying roller pair is set.

Printing plate processing apparatus

A brush roller is structured such that a web body having wire members is wound in a helical manner around a roller main body to which an axial end member is mounted. A fastening member is mounted to a rotary shaft of the axial end member, and one end of the web body is fixed to a holding member which is arranged between the fastening member and the axial end member so as to freely rotate relatively. The holding member relatively rotates in a winding direction due to an urging force of a torsional coil spring when elongation occurs in the web body, thereby preventing slack from occurring in the web body.

In a shutter facing an aperture portion in a partition plate in a photosensitive material processing device, a blocking member, formed substantially in a semicircular cylindrical shape, is placed by the rotation of a shaft between blades thereby closing the aperture portion. The opening between the blades is opened by rotating the blocking member integrally with the shaft so that a photosensitive material can pass through. Multi-leveled surfaces are formed on the top surface of a guide plate. Aperture portions for mounting rollers with adaptors are formed in an alternating pattern on the surfaces. A plurality of protruding guide ribs are provided extending across the surfaces. A plurality of brush roller parameters are adjusted so that a winding mark index defined by the parameters falls within a predetermined range. Rollers are washed when a finisher control system is restarted after an unforeseen long stoppage.

Photosensitive material processing device

In an automatic film developer, measurements are taken of internal temperature parameters during a warm up phase. Based on measured temperature values a time for completing the warm up phase is calculated. The calculated time for warm up is displayed so that it can be read by an operator. When the calculated time for warm up completion has elapsed, an indication is displayed that the film developer is operational. During the warm up phase, film is not allowed to advance through the automatic film developer. When the calculated time for warm up completion has elapsed, advance of film through the film developer is automatically started.

Automatic developing apparatus and method

A photographic processing apparatus includes a replenisher supplying mechanism for forcibly supplying a remaining portion of a replenisher if the replenisher remains in a replenisher container or pack when the processing of a predetermined quantity of photosensitive material has been finished and a controlling mechanism which displays an abnormality message on a display if the forcibly supplied quantity of replenisher has exceeded a predetermined quantity. If it is detected that the replenisher pack has become empty before the processing of the predetermined quantity of photosensitive material is finished, the abnormality message is displayed. If all the quantities of replenishers forcibly supplied from a plurality of replenisher packs are not more than predetermined quantities, only a message for replacing the replenisher packs is displayed. If the quantity of replenisher forcibly supplied from one of the replenisher packs is not more than the predetermined quantity, and if the replenisher pack has become empty before the processing of the predetermined quantity of photosensitive material is finished, both the abnormality message and the replace message are displayed. It is thus possible to ascertain the timing of replacing a replenisher pack not provided with a level sensor and to ascertain the state of a replenisher pump.
