    • A test sample color comparison device is disclosed which has a casing unit with an insertion slot for inserting a color test sample therein, and a display section for displaying the color test sample adjacent at least one of a plurality of reference color shades, as the reference color shades are successively moved into position adjacent the color test sample by a manipulation wheel. When an operator determines that a reference color shade adjacent the test sample corresponds in color to the color of the test sample, he pushes a switch to cause a readout of stored information corresponding to the reference color shade then adjacent the test sample. Readout of the stored information is based on a bit pattern set by a plurality of converter switches which are turned on and off in different patterns which correspond to the different color shades as the reference color shades are moved into position by the manipulation wheel. An uneven pattern code section moves in association with the manipulatable wheel and actuates the converter switches. A preferred uneven pattern code section is arranged so that all of the converter switches are actuated roughly equally during a full rotation of the manipulatable wheel, and so that only one of the converter switches is switched on or off during incremental movement of the manipulable wheel.
    • 公开了一种测试样品颜色比较装置,其具有壳体单元,其具有用于在其中插入颜色测试样本的插入槽,以及显示部分,用于显示与多个参考色调中的至少一个相邻的颜色测试样本作为参考 颜色阴影通过操纵轮相继移动到与彩色测试样本相邻的位置。 当操作者确定与测试样品相邻的参考色调对应于测试样品的颜色时,他推动开关以使得读出与参考色调相对应的存储信息,然后与测试样品相邻。 所存储的信息的读出基于由多个转换器开关设置的位模式,该多个转换器开关在与操作轮移动参考色调的情况下以不同的模式对应于不同的色调来打开和关闭。 不均匀的图案代码部分与可操纵的轮相关联地移动并致动转换器开关。 布置优选的不均匀图案编码部分,使得在可操纵轮的完全旋转期间,所有转换器开关大致相等地致动,并且使得在可操纵轮的增量运动期间只有一个转换器开关被接通或关闭。
