Title:
ユーザが制御したインク色を用いる筆記用具および筆記用具の出力色を制御する方法
Document Type and Number:
Japanese Patent JP4023606
Kind Code:
B2
Abstract:
A writing instrument, e.g., a pen, incorporates at least three color ink chambers: cyan (C), yellow (Y), and magenta (M). The ink from the three chambers can be mixed in varying ratios to provide an output ink of any conceivable color. Ink jet nozzles, preferably thermal ink jet nozzles, are used to output the ink from the chambers. The ink may be output to a mixing chamber, onto a roller ball or other transfer member, or directly to the writing medium. Consequently, the ink output by the pen can be adjusted by the user to any desired color.
