ABSTRACT:
The present invention provides an embroidering machine which is made up of a thread station at which a plurality of spools of different colored threads are installed; a frame on which a work-piece is carried in tension mode; an embroidery stitching mechanism having a plurality of needles to which the colored threads are routed, respectively, and stitching the work-piece with the colored thread routed to a selected needle; a color recognizing device for recognizing the color of each of the threads routed to the respective needles; data reading means for reading embroidering data relating to the embroidering pattern; a comparing device matching a color indication included in the embroidering data with the color of each of the threads which is recognized by the color recognizing device, the comparing device selecting one of the threads to which the thread of the matched color is routed for determining the selected needle; and a control device for controlling the selected needle of the embroidery stitching mechanism and the frame to produce an embroidering pattern on the work-piece with the matched color thread. The color recognizing device includes an emitting portion from which a beam of light is emitted to the corresponding thread, a receiving a reflection beam of light reflected from the thread, and a light shielding device provided between the emitting portion and the receiving portion for the prevention of an entrance of light into the receiving portion except for the reflection beam of light.
