    • An image forming apparatus includes: a latent image forming unit forming a latent image; a transfer body on which a reference index for setting an output start time point of image data is formed; a detecting unit facing the reference index and outputting a detection signal changing in accordance with passing of the reference index; a measuring unit measuring change duration time; and a controller controlling the output start time point with the detection signal. The controller starts a first period during which change of the detection signal is ignored, according to first change of the detection signal, starts a second period after the first period, regards change of the detection signal occurring first in the second period as a reference of the output start time point if the change duration time is longer than a predetermined period, and ignores change of the detection signal after the change occurring first.
    • 图像形成装置包括:潜像形成单元,形成潜像; 其上形成有用于设置图像数据的输出开始时间点的参考索引的转印体; 检测单元,其面向参考索引并输出根据参考索引的通过而改变的检测信号; 测量单位测量变化持续时间; 以及用所述检测信号控制所述输出开始时间点的控制器。 控制器开始第一期间,根据检测信号的第一次变化,检测信号的变化被忽略,在第一期间之后开始第二期间,将第二期间中首先出现的检测信号的变化作为基准 如果改变持续时间长于预定周期,则输出开始时间点,并且忽略首先发生改变之后的检测信号的改变。

    • A droplet discharging apparatus has a flow path connected to a liquid supply path. A nozzle is located downstream of the flow path and discharges liquid drops. A pressure generation element generates pressure for discharging the liquid from the nozzle. The flow path is bent and has a first flow path connected to the liquid supply path and a second flow path connected to the downstream side of the first flow path and causing the liquid to flow in the different direction from the first flow path. That portion of the bend which is from an outer corner of the bend to an outer wall portion of the second flow path is formed in a smooth shape. At the connected sections, the width of the second flow path normal to the direction of flow of the first flow path is set smaller than the width of the first flow path.
    • 液滴喷射装置具有连接到液体供应路径的流路。 喷嘴位于流路的下游,并排出液滴。 压力产生元件产生用于从喷嘴排出液体的压力。 流路弯曲,并且具有连接到液体供给路径的第一流路和连接到第一流路的下游侧的第二流路,并使液体沿与第一流路不同的方向流动。 从弯曲部的外角到第二流路的外壁部的弯曲部形成为平滑的形状。 在连接部分,将与第一流路的流动方向垂直的第二流路的宽度设定为小于第一流路的宽度。
