摘要： A printer (100) includes a recording medium holding unit (201) that holds a long, wound strip-like recording medium so as to enable the recording medium to be pulled out starting with a front end on the outer circumference side thereof, a recording unit (203) that pulls out the recording medium held by the recording medium holding unit (201) to a side higher in a vertical direction than a position for pulling out from the recording medium holding unit (201) and that executes a recording operation for the pulled-out recording medium, and a second cutter mechanism (221) that is disposed beneath the recording medium holding unit (201) in the vertical direction and that cuts the recording medium for which the recording operation is executed by the recording unit (203) at the back end thereof separated from the front end by a predetermined length. A drawing position of the recording medium into an inversion path (219) is arranged to be lower than the recording medium holding unit (201) and the recording unit (203) in the vertical direction.

摘要： Irregularities in the density that can occur in printed images of a thermal transfer printer due to mechanical variations or variations in thermal characteristics in the thermal head are more easily and accurately corrected as compared to cases not having the features of the disclosed invention. The thermal transfer printer includes a thermal head including heating elements and causing the heating elements to generate heat and transfer ink onto a sheet to print an image on the sheet, a storage unit for storing a first correspondence between a heating element in the thermal head and a correction amount of energy applied to the heating element and a second correspondence between a density of an image to be printed and an adjustment coefficient of the correction amount, and a control unit for correcting energy applied to each heating element by an amount obtained by multiplying the correction amount for the heating element obtained from the first correspondence by the adjustment coefficient obtained from the second correspondence according to a density of an image to be newly printed. The first correspondence is generated from a density distribution of a test image printed based on image data of a single tone.

摘要： When sub-images are sequentially transferred and connected together to form a larger image than would be possible with a single transfer operation, the occurrence of a color change in the overlapping region of the sub-images is suppressed and the width of the overlapping region is reduced as much as possible. Color image data are divided into image data of two sub-images containing an overlapping region and having edges that coincide for each color ink transferred to paper. Color values of the color image data in the overlapping region are converted by using a color conversion factor group created in advance for each position on the overlapping region so as to cancel out a color change that occurs in the overlapping region when the sub-images are transferred with one overlapping the other. The image data of the sub-images are corrected by adjusting converted color values in the overlapping region by using a correction factor for print density at each position on the overlapping region. A color image is formed by sequentially transferring the sub-images in accordance with corrected image data thereof so that the sub-images overlap at the overlapping region.

摘要： A first feeding unit (130) is configured that is provided in a first printing unit (110) that includes a first recording unit (203) that executes a recording operation for a long strip-like recording medium pulled out from a first holding unit (201) that holds the recording medium in a wound state. The first feeding unit (130) further includes a pair of feeding rollers (225) that sort the recording medium discharged from the first printing unit (110), to the side of a second printing unit (120) stacked on the first printing unit (110) or to the side opposite to that of the second printing unit (120). The first feeding unit (130) temporarily accommodates the sorted recording medium and thereafter, feeds the recording medium to a guide path (229), and sorts the recording medium fed by the pair of feeding rollers (225), to the side of the second printing unit (120) using a sorting part (226).

摘要： Damage caused to a transfer medium due to heat when partially using transfer material regions is suppressed. An image forming apparatus (1) includes a transporting unit (4A, 4B) which transports a belt-like transfer medium (4) on which transfer material regions (Y, M, C, OP) of a first size respectively corresponding to transfer materials are arranged in a predetermined order in a repeated manner along a longitudinal direction thereof, and an image forming unit (3) which transfers the transfer materials in sequence by heating the respective transfer material regions and thereby forms on a recording medium an image with the first size or an image with a second size which is not larger than one half the first size. When forming an image with the second size, the image forming unit either uses unused portions of transfer material regions that have already been used to form an image with the second size or uses new transfer material regions on the transfer medium. When forming the image with the second size by using the new transfer material regions, the image forming unit performs the image formation at a slower speed than when forming an image with the first size.
