摘要:
A processor has a rotatable drum housed within an enclosure chamber. Processing solution is applied to the surface of the rotating drum and forms a film of solution around the periphery. The media to be processed is fed around the periphery of the rotating drum with its sensitized surface facing the drum.
摘要:
The present invention provides for a processor or processing arrangement which includes a replenishment system that meters or dispenses an amount of replenishment solution in direct relation to an amount of photosensitive media that passes through the processor or processing arrangement. The replenishment system includes a dispensing chamber and a cam roller that is operationally associated with a conveying roller. The cam roller engages a valve on the dispensing chamber. When the valve is moved to an open position in relation to a rotation of the cam roller, an amount of processing solution is metered out of the chamber in an amount related to the amount of rotation of the conveying roller.
摘要:
A photographic processor and method of operation is disclosed. The processor includes a circular drum having first and second film processing paths, and a disk positioned inside the drum. The disk comprises a first set of disk teeth for engagement with perforations on a first type of film and a second set of disk teeth for engagement with perforations on a second type of film. The first and second set of disk teeth are positioned along a portion of an outer periphery of the disk. The processor also includes a circular dryer for drying the processed film. The dryer extends around an outer periphery of the drum.
摘要:
A photographic processor having a circular processing drum is shown. The circular processing drum of the processor of the present invention includes a disk that is positioned inside the drum. In order to accommodate different types of film, the circular processing drum is adjustable to change the width and thereby, change a size of the film path within the circular processing drum.
摘要:
A photographic processor and a dryer for drying photographic material. The dryer comprises a path through which the photographic material extends wherein at least one slack loop is provided in the photographic material. An adjustable roller is provided along the path to adjust a size of the slack loop and an air supply arrangement is adapted to provide drying air to the slack loop. The air supply arrangement supplies air to a frame member that has slots along at least one wall. A sliding member is provided within the frame member to open and close the slots in accordance with the size of the slack loop. This enables a supply of drying air directly on the media and further permits the automatic adjustment of the amount of air being supplied in accordance with the size of the slack loop or the length of the media being dried.
摘要:
The present invention relates to a photographic processor and a method of processing photographic film which utilizes a circular processing drum and a disk positioned inside the drum. In the arrangement of the present invention, a tubular shaft has one end that is positioned at the central opening of the disk, and at least one processing solution delivery tube extends through the tubular shaft. The at least one processing solution delivery tube has a first end associated with a processing solution source and a second end which opens to a film path in the circular processing drum.
摘要:
A method and processor for processing photosensitive media. The processor includes a narrow processing channel for holding a processing solution, at least one delivery opening for delivering the processing solution to the narrow processing channel, an outlet for allowing processing solution to be withdrawn from the narrow processing channel, and a recirculation system for delivering and circulating a predetermined batch amount of the processing solution through the narrow processing channel from the outlet to the at least one narrow delivery opening for processing a predetermined amount of photosensitive media passing through the narrow processing solution. The batch amount of processing solution only when media is provided in the processing channel. The processor also included an emptying system for removing the processing solution from the narrow processing channel and the recirculation system when the photosensitive media is not being processed through the narrow processing channel.
摘要:
A dryer for drying photographic material and a transfer assembly for transferring processed photographic film from a processor to the dryer. The dryer comprises a path through which the photographic material extends wherein at least one slack loop is provided in the photographic material. An adjustable roller is provided along the path to adjust a size of the slack loop and an air supply arrangement is adapted to provide drying air to the slack loop.
摘要:
The present invention provides for a circular processing drum that defines a processing chamber therein. The circular processing drum includes a first media path for media of a first type which includes a first set of grooves in opposing walls of the processing drum, and a second media path which includes a further set of grooves in the opposing walls of the processing drum. The combination of the first and second media paths provides for a drum that is capable of processing multiple types of media while utilizing a minimum amount of space.
摘要:
A belt driven rack and tank processor includes a belt for driving photosensitive material through a relatively thin processing channel formed by the rack and tank of the processor. The belt travels around a core that displaces fluid within the apparatus so as to provide for a low volume processor. The processor further includes spring loaded engaging rollers which facilitate the conveyance of cut sheets through the processor.
