  • Patent number: 12068005
    Abstract: A tape reel according to an embodiment of the present technology includes: a cylindrical reel hub that includes an outer periphery portion, a tape being wound on the reel hub. The reel hub is formed of a material in which a deformation amount when a load of 300 N is applied radially inward to an axial center of the outer periphery portion is 0.3 mm or less and a water absorption rate is 0.1% or less.

  • Publication number: 20230249941
    Abstract: [Object] To provide a method of producing a tape cartridge that includes a reel hub, a tape reel, and a reel hub, which are capable of achieving desired molding quality in single molding. [Solving Means] A tape cartridge according to an embodiment of the present technology includes: a first flange; a second flange; and a reel hub on which a tape is wound. The reel hub is disposed between the first flange and the second flange. The reel hub includes a cylindrical metal ring and a molded body formed of a synthetic resin. The molded body includes a first resin portion formed on an inner peripheral surface of the metal ring and a second resin portion formed on an outer peripheral surface of the metal ring. The first resin portion includes a plurality of first recessed portions formed at intervals in a circumferential direction of the metal ring.

  • Patent number: 7751155
    Abstract: In an ink-jet printing device which has an ink-jet recording head in which a plurality of nozzles are formed, and forms an image based on multi-level image data, a gamma correction parameter is selected according to discharging characteristics of the recording head to an input gradation level or according to lightness characteristics of a printed image to an input gradation level, and an image is formed based on the selected gamma correction parameter. For example, even when there is a variation in lightness characteristics of recording heads as in FIG. 9, an optimal gamma correction parameter is selected for each recording head and the image is formed. Thus, a constant image quality is obtained even if the recording heads are exchanged.
