摘要： An ink jet printer having a pair of supporting portion for supporting from below both side portions of a sheet to be discharged after characters are printed on the surface of a sheet. At least one of the pair of supporting portion includes a roller, which may be either a driving roller, which conveys discharging sheets from the sheet discharge section, or a driven roller, which rotates upon contacting a discharging sheet to convey the sheet from the sheet discharge section. As a consequence, the sheet is discharged smoothly, without reducing sheet feeding accuracy even when stiff sheets are printed upon by the printer.

摘要： A supporting part 11 arranged nearer to a head 1 than a pair of carrier rollers 3 and on the same side as a rib 2a based upon paper S for supporting the side Sb of the paper S toward the head 1 is provided. The supporting part 11 is formed so that it is wider than the rib 2a. The driving roller 3a1 of the pair of carrier rollers and the supporting part 11 are overlapped when they are viewed from a direction in which paper is carried. A ringed member 4 may be also provided in place of overlapping the supporting part 11 and the driving roller 3a1.

摘要： A printer is provided wherein printing can be executed continuously after the rear end of printing paper comes off a paper feeding roller without loss in print image quality. Specifically, the position of a point nipped by a paper ejecting roller is placed higher than the position of the top face of a record medium regulating part, and the surface of the paper located upstream of the paper ejecting roller is pressed downward. The position of the top face of the record medium regulating may be varied and backed up. As a result, the rear end of the paper being pressed downward may be caused not to touch the print head. The printer is also provided with a driving controller, that executes an interlace recording method, and the end on the upstream side of the flat top face of the record medium regulating part is located within a range of the array of dot formation elements. The drive controller records a first line of a record object using dot formation elements located at the rear end of the recording head, after the front end of the record medium reaches the end on the upstream side of the top face of the record medium regulating part and is therefore properly positioned. Subsequently, the interlace recording method is executed by repeating sub scanning, by a predetermined sub scanning distance, and main scanning by the recording head.

摘要： A capping device for an ink jet printer includes a cap supported on a cap support member adapted to press the cap against a print head with a uniform pressure distribution despite variation in the positional relationship between the print head and the cap support member. The uniform pressure distributed is enhanced by supporting the cap by the support member in such a manner to permit the cap to pivot in at least two degrees of freedom. After the cap is sealed around an ink orifice of the printer, a preliminary suction operation reduces the pressure within a cavity defined by the cap and the print head. The pressure within the cavity is then returned to atmospheric pressure and then reduced again, but to a level which will not interfere with the ink meniscus level in the print head. The first period of suction lasts longer than the second suction period. By providing the capping device with tubes which resist the corrosive effects of ink and prevent gas from penetrating therethrough, excessive air buildup within the print head can be avoided.
摘要翻译： 用于喷墨打印机的封盖装置包括支撑在帽支撑构件上的帽，其适于将打印头压靠在打印头上，均匀的压力分布，尽管打印头和盖支撑构件之间的位置关系发生变化。 通过支撑构件以这样的方式支撑帽来增强分布的均匀压力，以允许帽以至少两个自由度枢转。 在盖子围绕打印机的墨水孔密封之后，初步抽吸操作降低了由盖子和打印头限定的空腔内的压力。 然后将空腔内的压力恢复到大气压力，然后再次减小，但是达到不会干扰打印头中的墨水弯月面水平的水平。 第一次抽吸持续时间比第二次吸入时间长。 通过为封盖装置提供防止油墨的腐蚀作用并防止气体穿过其中的管子，可以避免在打印头内产生过多的空气积聚。
