    摘要： 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.

    摘要： An apparatus is provided for making color comparisons between a test sample and a plurality of color samples. The color samples are arranged on a circle on a rotatable member and are successively moved into position adjacent a test sample. When an operator determines that a color sample adjacent the test sample is closest in color to the test sample he operates a switch which causes a stored numerical value associated with that sample to be read out and displayed on a display device.
