    • An operation condition detecting and displaying device for use in conjunction with a rotary indication device including a control circuit for energizing drive means adapted to successively switch and display a plurality of indicating members in series when the drive means receives actuation signals. The operation condition detecting and displaying device comprises at least one abnormal operation condition indication member, a switch cam mounted on the rotary member of said rotary indication device, a first switch in said control circuit to be actuated by said switch cam so as to energize said drive means for successively switching and displaying said indication members, an operation condition detection circuit for generating a check signal when said detection circuit detects an abnormal operation condition and a second switch in said control circuit to be actuated by said cam disc and adapted to energize said drive means when said abnormal condition indication member is positioned in the displaying position while said indication device is operating under normal condition, so as to pass the indicattion member over the displaying position and also energize the drive means when an abnormal condition occurs in said indication device so as to hold said abnormal condition indication member in said displaying position.

    • A display device having a plurality of segment light polarizers for receiving incident light thereon and rotatable independently to jointly define sequentially different numerals in dependence upon their relative angular orientation. A common light polarizer is mounted sandwiched between two transparent plates forwardly of the light polarizer for polarizing light from the segment light polarizers and for viewing of the different numerals upon relative angular orientation of the segment light polarizers and relative angular orientation to the common light polarizer. The light polarizers are driven rotationally independently in timed relationship. A mask between the two transparent plates has openings therethrough positioned for viewing the numerals.
    • 一种显示装置,具有多个分段光偏振器,用于在其上接收入射光并且可独立旋转,以根据其相对角度取向共同界定顺序地不同的数字。 普通的光偏振器安装在夹在光偏振器前面的两个透明板之间,用于偏振来自光束偏振片的光,并且在相对角度取向的分段光偏振器和与公共光偏振器相对的角度方向上观看不同的数字。 光偏振器以时间关系独立地旋转驱动。 两个透明板之间的掩模具有通过其定位的开口用于观察数字。
