    • In an ink jet printer, a recording unit in which an ink cartridge is detachably mounted has a cartridge removal preventing member so that the ink cartridge is prevented from being carelessly removed therefrom, and a moving mechanism is provided which, when the recording unit is mounted on the carriage, moves a first electrical connecting section towards a second electrical connecting section so that the first and second electrical connection section are connected to each other with the aid of an energizing member under pressure, and, when the recording head is removed from the carriage, moves the first electrical connecting section away from the second electrical connecting section against the elastic force of the energizing member, whereby the recording head is detachably mounted on the carriage, and the former is positively electrically connected to the latter.
    • 在喷墨打印机中,其中可拆卸地安装墨盒的记录单元具有墨盒拆卸防止部件,从而防止墨盒被不小心地从其中移除,并且提供移动机构,当安装记录单元时 在滑架上移动第一电连接部分朝向第二电连接部分,使得第一和第二电连接部分借助加压构件在压力下彼此连接,并且当记录头从 滑架将第一电连接部分抵靠着激励部件的弹力移动离开第二电连接部分,由此记录头可拆卸地安装在滑架上,并且前者与后者正确地电连接。

    • A printer using a line-type ink jet recording head. The line-type head has pressure producing chambers formed by dividing nozzle openings extending in a recording paper width direction with vertical side walls and upper and lower ink flow paths which communicate with each other through the pressure producing chambers and extend in a horizontal direction. Each ink flow path has an inlet for replenishing ink and an outlet for discharging the ink. A plurality of pressure producing elements are provided for applying varied pressures to the pressure producing chambers for jetting ink droplets. A sealing member selectively seals the nozzle openings by abutting on the nozzle openings when the recording head has been evacuated to a predetermined position. An ink tank is connected to the inlets and the outlets through pipes, and an ink stream producing device is arranged in the pipes, for producing streams causing the ink to flow from the ink tank to the lower ink flow path and then to the upper ink flow path through the pressure producing chambers.
    • 一种使用线型喷墨记录头的打印机。 线型头部具有通过将沿记录纸宽度方向延伸的喷嘴开口与垂直侧壁分开而形成的压力产生室,以及通过压力产生室彼此连通并沿水平方向延伸的上下油墨流动路径。 每个油墨流动路径具有用于补充油墨的入口和用于排出油墨的出口。 提供了多个压力产生元件,用于向喷射墨滴的压力产生室施加不同的压力。 当记录头已被抽空到预定位置时,密封构件通过邻接在喷嘴开口上选择性地密封喷嘴开口。 墨水罐通​​过管道连接到入口和出口,并且墨水流生成装置布置在管道中,用于产生使墨水从墨水罐流到下部墨水流动路径,然后到达上部墨水的流 通过压力产生室的流动路径。
