    • A detection unit to optically detect a discharge condition of a droplet is disclosed. The detection unit includes a light emitting element and a light receiving element disposed on opposite sides of an area through which a droplet discharged from a droplet-discharger passes. A diaphragm plate having an aperture and another diaphragm plate having at least two apertures arranged at a pitch in a discharge direction are respectively disposed near front surfaces of the two elements. When light emitted from the light emitting element passes through the apertures, two light beams are received by the light receiving element. When the droplet is discharged and passes in front of the apertures, the two light beams are blocked sequentially by the ink droplet, which causes the quantity of light received by the light receiving element to change, thereby inducing a change in an output from the light receiving element. Based on the change in the output, a discharge-condition of the droplet is determined.
    • 公开了一种用于光学检测液滴的排出状态的检测单元。 检测单元包括发光元件和设置在从液滴排出器排出的液滴通过的区域的相对侧上的光接收元件。 具有开口的隔膜板和具有沿排出方向以节距排列的至少两个孔的另一隔膜板分别设置在两个元件的前表面附近。 当从发光元件发出的光穿过孔时,两个光束被光接收元件接收。 当液滴被排出并通过孔的前方时,两个光束被墨滴顺序地阻挡,这导致由光接收元件接收的光量改变,从而引起来自光的输出的变化 接收元件。 基于输出的变化,确定液滴的排出条件。

    • A recording apparatus for performing recording uses a carriage mounted with a recording head moving along a guide shaft. The recording apparatus includes a magnetic linear encoder consisting of a scale element magnetized and a detection unit for detecting magnetized information magnetized to the scale element. Provided also are clicks formed on any one of the detection unit and the carriage and click engaging portions formed in the other one of the detection unit and the carriage. The clicks engage with the click engaging portions, whereby the detection unit is snap-locked to the carriage. This enables the detection unit of the magnetic linear encoder to be readily attached to the carriage and besides, when attached, prevents disorder of the information magnetized to the scale element. Further, even when a position of the carriage shifts corresponding to sheets having different thicknesses, a sliding load of the carriage does not change. Deformation and abrasion of the scale element of the magnetic linear encoder are restrained as much as possible. Moreover, the abrasion of bearings of a head of the magnetic linear encoder is eliminated.
    • 用于执行记录的记录装置使用安装有沿着引导轴移动的记录头的滑架。 该记录装置包括磁性线性编码器,该磁性线性编码器包括磁化的刻度元件和用于检测磁化到刻度元件的磁化信息的检测单元。 还提供了形成在检测单元和托架中的任何一个上的点击,以及形成在检测单元和托架中的另一个中的滑架和点击接合部。 棘爪与点击接合部分接合,由此检测单元卡扣到支架上。 这使得磁性线性编码器的检测单元能够容易地附接到托架,此外,当附接时,防止磁化到刻度元件的信息的混乱。 此外,即使当托架的位置对应于具有不同厚度的片材移动时,托架的滑动负载也不改变。 磁性线性编码器的刻度元件的变形和磨损尽可能地受到限制。 此外,消除了磁性线性编码器的头部的轴承的磨损。
