    摘要: An arrangement for recording on programming tape the color pattern of, for example, fabric material. A scanning head having photosensitive apparatus scans the color pattern to be recorded on the tape, in a grid fashion. The photosensitive apparatus detects the colors on the pattern and converts the optical signals thus realized into corresponding electrical signals. After amplification, these signals from the photosensitive apparatus are converted into normalized pulses by being passed through pulse shapers. The latter provide pulses of constant amplitude and duration in the form of rectangular-shaped pulses. The latter are then applied to a color recognition circuit which provides a signal permitting recording on the programming tape when all designated colors on the pattern have been recognized. Through a systematic and orderly sequence of scanning and tape recording locations, the pattern and its color information is transferred onto the tape. This programming tape may then be used for controlling various machines, as for example, knitting or weaving machines for knitting or weaving predetermined color patterns.
