    摘要: A blood vessel image input apparatus is provided which is capable of acquiring a high-precision image of blood vessels of a body part, such as a finger, even if the finger is swept at a non-constant speed. The apparatus includes a solid-state line image sensor, a light source for illuminating the inside of the finger with light, an imaging optical system adapted to focus the light, emitted from the light source and passed through the inside of the finger, on the solid-state line image sensor such that a blood vessel image representing a network structure of veins in the finger is formed on the solid-state line image sensor, and a blood vessel image forming unit adapted to form a complete image of blood vessels by connecting a plurality of partial blood vessel images captured by the solid-state line image sensor while sweeping the finger.

    摘要: A printing method comprises the steps of: in a first movement, moving a print head to form dots on a medium at aperiodic intervals in a moving direction of the print head, wherein the print head includes N pieces of nozzles arranged at a constant pitch in a direction that intersects with the moving direction, wherein the N pieces of nozzles are for forming N dots of a same color, and wherein N is an integer of at least two; in second through M-th movements, moving the print head to form, on the medium, the rest of the dots that were not formed in the first movement, wherein M is an integer of at least two; and repeating the first through M-th movements to print information on the medium.

    摘要: An ink jet recording head that is formed by laminating a plurality of thin plate members, each having a plurality of holes. The holes of the adjacently stacked thin plate members cooperate to form ink flow paths each continuously extending to communicate a nozzle opening with a respective pressure producing chamber, which is connected to an ink supply section. In such ink jet recording head, the holes can be aligned or shifted with respect to each other, and allow ink to flow smoothly, thus preventing stagnation of air bubbles contained in the ink within the print head. Further, the nozzles openings are arranged in arrays in an auxiliary scanning direction. The nozzle opening arrays are divided into three groups spaced apart from each other at a predetermined interval in a main scanning direction. Nozzle openings belonging to groups arranged on both sides of the middle group are positioned vertically between adjacent nozzle openings of the middle group. A nozzle opening of the middle group is positioned uppermost or lowermost in the auxiliary scanning direction, so that lines printed by the nozzle openings belonging to the groups arranged at both sides interpose a line printed by the nozzle openings of the middle group to reducing inter-line error due to misalignment of the recording head with respect to a printing sheet.

    摘要翻译: 一种喷墨记录头,其通过层叠多个薄板构件而形成,每个薄板构件具有多个孔。 相邻堆叠的薄板构件的孔协作形成油墨流动路径,每个油墨流动路径连续延伸以使喷嘴开口与相应的压力产生室连通,该压力产生室连接到供墨部分。 在这样的喷墨记录头中,孔可以相对于彼此对准或移位,并且允许墨流畅地流动,从而防止包含在打印头内的墨中的气泡的停滞。 此外,喷嘴开口在辅助扫描方向上排成一列。 喷嘴开口阵列在主扫描方向上以预定间隔彼此间隔开分成三组。 属于中间组两侧的组的喷嘴开口垂直定位在中间组的相邻喷嘴开口之间。 中间组的喷嘴开口在辅助扫描方向上位于最上侧或下侧,使由属于设置在两侧的组的喷嘴开口印刷的线插入由中间组的喷嘴开口印刷的线, 由于记录头相对于打印纸不对准导致的线错误。
