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.

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 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 a photosensitive material processing apparatus of the present invention, a brush roller used in a pre-water-washing section and a developing section is formed by winding a slender band wherein bristles are woven into a knitted fabric onto the peripheral surface of a roller which is a core member. This makes it possible to arrange the bristles closely and uniformly on the whole of the peripheral surface of the roller. Therefore, the brush roller can be applied to a photopolymer plate, which uses a non-polymerizable layer as a photosensitive layer and requires strong rubbing without causing brushing unevenness.

Photosensitive material automatic-processing apparatus

In a moire apparatus having a projection grating,, three-dimensional data of an object to be measured,is computed from the moire fringe observed while the projection grating,is moved, a distance-measuring reference point P (X, Y, Z) on the object,is selected from the three-dimensional data, and the distance L between the distance-measuring reference point P (X, Y, Z) and a taking lens,is measured. The distance L can automatically be measured by detecting the peak of video output signal of a CCD camera,while moving its lens,L along the optical axis. Also, the distance-measuring reference point P (X, Y, Z) may be displayed with a flag on a monitor,for observing the moire fringe, and the distance between the object,and the taking lens,may be measured with reference to the flag-displayed pixel. A stationary grating,having a pitch identical to that of the projection grating,is disposed near the projection grating,, so as to form a moire fringe. From the change in this moire fringe generated when the projection grating,is moved, the amount of movement of the projection grating,is computed. The change in moire fringe is detected when a photocell,placed near the stationary grating,detects the illuminance of the moire fringe.

In a heat developing section, heater boxes heated by sheet-like heaters are disposed vertically in pairs between an insertion roller pair and a discharging roller pair. When a heat developing photosensitive material is fed between the heater boxes by the insertion roller pair with a photosensitive layer of the heat developing photosensitive layer facing upward, it is guided by a guide plate of a lower heater box and is conveyed with an air layer being constantly formed between an upper heater box and the heat developing photosensitive material. As a result, the heat developing photosensitive material is heated without the photosensitive layer thereof being pressed. Accordingly, the heat developing photosensitive material is uniformly heated with no wrinkles generated therein, and an image of high finished quality is formed.

Heat developing apparatus

A photosensitive material processing apparatus is equipped with a drying section in which a photosensitive material processed with a processing solution is conveyed by a plurality of rollers and dried by drying air from a drying air blowing device. In the photosensitive material processing apparatus, a plurality of heating rollers is disposed to form a part of the above-described plurality of rollers and whose surfaces are heated by a heat source. A control means effects on-off control for the heat source during processing of the photosensitive material to set the surface temperature of each of the plurality of heating rollers and to control the drying air blowing device to lower the surface temperature of each of the plurality of heating rollers by the drying air during a standby period. Accordingly, during the standby period, the surface temperature of each of the plurality of heating rollers is lowered forcibly by the drying air, so that overshooting is restricted.

A method of and an apparatus for controlling drying of a photographic material in which, by controlling respective temperatures of a contact-heating device and warm air, temperatures can be controlled to the minimum temperature necessary to provide the photographic material with optimal effects so that the relative contributions of drying the photographic material by the contact-heating device and the warm air are always constant.

Method of and apparatus for controlling drying of photographic material

A photosensitive material drying apparatus equipped with a plurality of rollers, which are disposed along a direction of transport of a photosensitive material and form a transport path and which are able to provide heat to the photosensitive material, and a plurality of hot air supplying portions, which blow hot air toward the photosensitive material. The rollers and the hot air supplying portions are disposed such that portions having drying irregularities which occur on surfaces of the photosensitive material, due to the photosensitive material receiving heat from the rollers and from hot air blown from the hot air supplying portions, in accordance with irregularities in a transport speed of the photosensitive material due to driving irregularities in a substantially uniform cycle of the rollers, are scattered substantially evenly on the surfaces of the photosensitive material along the direction of transport thereof. Unevenness on the surfaces of the finished photosensitive material drying irregularities can thereby be prevented.
