    • A thermal head, in which the catching of a foreign object on a partial glaze is prevented and the head pressure of the partial glaze is not reduced, is provided such that the image quality is improved by preventing the occurrences of line voids, irregularities, and roughness. In a thermal head which includes a partial glaze, which protrudes and whose cross-sectional configuration is substantially arc-shaped, on a recording material opposing surface, the radius of curvature of a heater portion on the partial glaze is less than 50 mm and the height of the partial glaze from the recording material opposing surface is 40 .mu.m or less. Further, the height of the partial glaze from the recording material opposing surface at the conveying direction upstream side of the recording material may be set lower than the height of the partial glaze from the recording material opposing surface at the conveying direction downstream side of the recording material with the heater portion therebetween.
    • 提供了防止部分釉上的异物捕获并且部分釉的头部压力不被降低的热敏头,使得通过防止线空隙,不规则性和不规则性的发生而提高图像质量 粗糙度 在记录材料相对表面上包括突出并且其横截面形状基本上呈弧形的部分釉的热敏头在部分釉上的加热器部分的曲率半径小于50mm,并且 来自记录材料相对表面的部分釉料的高度为40μm以下。 此外,可以将记录材料的输送方向上游侧的记录材料相对表面的部分釉料的高度设定为低于记录材料的输送方向下游侧的记录材料相对表面的部分釉料的高度 其间具有加热器部分的材料。

    • An image recording apparatus in which ink transfer from a donor sheet to an image-receiving sheet is carried out. The donor sheet has a size larger than the image-receiving sheet. The apparatus includes a rotating drum around which the image-receiving sheet and the donor sheet may be wound and laminated, and a squeeze roller. The squeeze roller has a middle portion with a fixed radius and a smaller radius portion at one or both ends. Outside an area for the image-receiving sheet, the drum has a first protruding mound portion with which the donor sheet is in surface-contact when the sheets are wound around the drum. A boundary of the smaller radius portion and the middle portion is positioned at an image-receiving sheet side of the first mound portion when the sheets are pressed against the drum.
    • 一种图像记录装置,其中执行从供体片到图像接收片的墨转移。 供体片具有大于图像接收片的尺寸。 该装置包括旋转鼓,图像接收片和供体片可围绕其旋转并层叠,以及挤压辊。 挤压辊具有在一端或两端具有固定半径和较小半径部分的中间部分。 在用于图像接收片材的区域外面,鼓具有第一突起的墩部分,当片材缠绕在鼓上时,供体片材与该片材表面接触。 当薄片被压靠在滚筒上时,较小的半径部分和中间部分的边界位于第一墩部分的图像接收片材侧。

    • An image transfer apparatus is arranged in a manner that an image bearing sheet on which an image is formed and a sheet on which an image is to be transferred are laminated, and the two sheets thus laminated are passed between a pair of heat rollers from an insertion table thereby to transfer the image formed on the image bearing sheet on the sheet on which the image is to be transferred. The image bearing sheet is placed on the insertion table, then the sheet on which an image is to be transferred is laminated on the image bearing sheet, and the two sheets thus laminated are inserted between the pair of heat rollers.
    • 图像转印装置被布置成使得形成有图像的图像承载片材和要传送图像的片材层叠在一起,并且将这样层压的两个片材从一对加热辊子之间通过 从而将形成在图像承载片上的图像转印在其上将要传送图像的纸张上。 将图像承载片放置在插入台上,然后将要传送图像的片层压在承载片上,并将这样层叠的两片插入在一对加热辊之间。

    • An image correction method structured such that supplied image data is converted into image data which must be output when supplied image data is output by a printing apparatus including a line-type head, the image correction method including steps of performing: CMS-conversion (21) of supplied image data in three dimensional or higher order; increase (30) of a gradation accuracy of image data after the CMS conversion has been performed; a correction process (31) of image data having the increased gradation accuracy; and a multivalued dither process (32).
    • 一种图像校正方法,其被构造为使得所提供的图像数据被转换为当由包括行式头的打印设备输出所提供的图像数据时必须输出的图像数据,所述图像校正方法包括以下步骤:CMS转换(21 )提供的三维或更高的图像数据; 增加(30)已经执行CMS转换之后的图像数据的灰度精度; 具有增加的灰度精度的图像数据的校正处理(31); 和多值抖动过程(32)。
