    摘要: A continuous tone thermal printing apparatus of the type having a printing station and a receiver drive station. The drive station repeatedly advances receiver back and forth through the printing station in conjunction with the advance of successive thermal transfer donor dye colors on a carrier web through the printing station to successively print the overlying different color image separations. The drive station preferably comprises a motor driven capstan roller mounted to bear against one surface of the receiver and a pinch roller mounted to bear and exert pressure against the other surface of the receiver and to press the receiver against the capstan roller and define a nip therebetween. The capstan roller has a high friction receiver engaging surface and is relatively hard and uncompressible, and the pinch roller has a low friction receiver contacting surface and is relatively soft and compressible, such that when the receiver is within the nip, it is driven in the advance direction by motor driven rotation of the high friction capstan surface, and the interfacial shear stress between each roller and the respective receiver surface in the nip area is minimized.

    摘要: A camera and method of camera operation for automatically determining usage condition of film in a cartridge utilizing a cartridge radial bar coded data disc to discriminate among a plurality of possible initial angular settings of the film spool during a film loading operation. The possible initial angular settings can be representative of exposed, partially exposed, fully exposed or processed film. At the start of film loading, the spool is rotated in the reverse direction and bar code element transition counts sensed by a pair of angularly spaced opto-sensors are accumulated. A count comparison between the two sensors is initially made to determine if the film is unexposed and, if so, film loading proceeds in normal manner, otherwise an alternative action is taken. In a simple camera, the loading is terminated. In a more sophisticated MRI capable camera, when the count comparison indicates the film is not unexposed, the camera controller calculates an angular position of one of the sensors relative to a predetermined reference position on the data disc, based on sensed element transitions and known element widths, to discriminate among spool settings indicative of partially exposed film, fully exposed film and processed film with appropriate actions initiated depending on the discriminated spool position.

    摘要: A thermal printer uses a relatively small dye-donor patches to produce images which are larger than the dye-donor patches. An image is formed by printing and merging of multiple sub-images. Each of the sub-images is smaller than one of the dye-donor patches. Merging of the sub-images is performed by generating data fields for sub-images and then distributing image data throughout overlapping segments of the sub-image data fields. A distribution of a portion of the image data is made in a first overlapping segment in a first pattern that is substantially non-linear. A second distribution of remaining image data is made in a second overlapping segment in a pattern that is complementary to the first pattern. When the overlapping segment are brought together, a merger zone between the sub-images becomes undetectable to an unaided human eye.

    摘要: A thermal printer is disclosed in which a receiver is driven back and forth relative to a printing head by a driving roller. The receiver is driven at a nip formed between the driving roller and a pinch roller. The pinch roller is adapted to contact only the receiver during the movement of the receiver. The receiver is thereby permitted to move at the surface speed of the driving roller with reduced shear forces being introduced by the pinch roller. Consequently, a pinch roller with a high length to diameter ratio is usable and images can be produced on wide receivers with narrow image-free borders. The images are produced with precise registration and image artifacts are reduced.

    摘要: A continuous tone themal printing apparatus of the type having a printing station and a receiver paper drive station. The drive station repeatedly advances receiver paper back and forth through the printing station in conjunction with the advance of successive thermal transfer donor dye colors on a carrier web through the printing station to successively print the different color separations. The platen drum in the printing station is coupled to a platen drag force mechanism for imparting reverse torque to the torque imparted by the drive station to impart a degree of tension to the receiver paper as it passes through the printing station that exceeds stick/slip variations in movement of the receiver paper therethrough by the sublimation of the dyes from the donor dye carrier web to the receiver paper in the creation of the image thereon. The platen drag force may be effected by overdriving a motor or generator or drag brake coupled to the platen drum.
