    • PURPOSE: To accurately determine that a pointer 20 has returned to a lower limit value in a vehicle speedometer. CONSTITUTION: The vehicle speedometer comprises an output coil 604 for outputting detection magnetic flux to the side of an output gear 410; a detection coil 603 for outputting a detection signal based on the detection magnetic flux that is inputted from the side of the output gear 410; and a magnetic body piece 601 that is arranged at the output gear 410 and forms a magnetic path for inputting the detection magnetic flux from the output coil 602 to the detection coil 603 when the pointer 20 returns to the lower limit value of a vehicle speed in a scale. A microcomputer 700A judges whether the pointer 20 has returned to the lower limit value or not based on output from the detection coil 603.
    • 目的:准确地确定指针20已经返回到车速表中的下限值。 构成:车速表包括输出线圈604,用于向输出齿轮410侧输出检测磁通量; 检测线圈603,用于根据从输出齿轮410侧输入的检测磁通输出检测信号; 以及设置在输出齿轮410处的磁体片601,并且当指针20返回到车速的下限值时,形成用于将来自输出线圈602的检测磁通量输入到检测线圈603的磁路 一个规模。 微计算机700A根据检测线圈603的输出判断指针20是否返回到下限值。

    • A character shielding-preventive pointer instrument is provided to allow light emitted from a character plate to pass through a pointer needle through a polarizer film, thereby preventing the pointer needle from shielding the character. A character shielding-preventive pointer instrument comprises a pointer needle(30), a step motor(20) configured to rotate the pointer needle, a micro computer(10) to control the driving of the step motor, at least one needle illuminating element(60) mounted below a rear end portion of the pointer needle, at least one character plate illuminating element(70) mounted below the character plate, and a polarizer film attached to a second section of the surface of the pointer needle and having selective permeability and non-permeability characteristics with respect to light depending on whether current is supplied thereto.
    • 提供一种字符屏蔽预防指针仪器,以允许从字符板发出的光通过指针针穿过偏光膜,从而防止指针针对字符屏蔽。 一种字符屏蔽预防性指示器,包括指针针(30),配置成旋转指针针的步进电动机(20),用于控制步进电动机的驱动的微型计算机(10),至少一个针照明元件 60),安装在指针针的后端部的下方,安装在字符板下方的至少一个字符板照明元件(70),以及安装在指针表面的第二部分上并具有选择性渗透性的偏光膜 取决于是否向其提供电流而关于光的非磁导特性。
