Then, the bridge plate 41 is attached so as to be able to be turned upside down by the bolt 50 (see FIG. 12), and the width of the guide groove 39 is determined according to the width of the tape T (diameter of the sequin S) by the downward regulating portions 45 and 44. It is like that. As shown in FIG. 13, a plurality of bridge plates 41 having different widths of the restricting portions 44 and 45 are prepared, and each bridge plate 41 is attached to the base 10 by a bolt 50 so as to be replaceable.

  According to the sequin tape supply device of the second embodiment, the bridge plate 41 is reversed so that the narrow restricting portion 45 or the wide restricting portion 44 faces downward, so that the tape guide groove is formed with one bridge plate 41. By changing the width of 39 in two ways, two types of tapes T having different sequin S diameters can be guided. Further, if the bridge plate 41 is replaced with another bridge plate 41 having different widths of the restricting portions 44 and 45, more types of tapes T can be guided. Therefore, when changing the size of the sequin S, the width of the tape guide groove 39 can be easily adjusted in any number of ways by a one-touch operation that simply reverses or replaces the bridge plate 41.

  Further, in the mounted state of the bridge plate 41, the center line of the restricting portions 44 and 45 is positioned by the bolt 50 at a position where it is aligned with the moving axis A of the delivery pin 20. For this reason, when the bridge plate 41 is reversed or replaced, the center line of the tape guide groove 39 is accurately aligned with the movement axis A of the delivery pin 20 by assembling the guide plate 40 with reference to the side surfaces of the restricting portions 44 and 45. Can be made. Therefore, the adjustment work incidental to the size change can be simplified, and the leading sequin S can be accurately supplied to the sewing position and can be sewn to the work cloth W with the needle 24.
