The frame can be freely supported. That is, the slide amount of Y slide rail 12 is used By attaching the embroidery frame enough to accommodate the largest embroidery frame, the same embroidery frame support device 7 can be used for various embroidery frames.

[0035] In the above-described embodiment, it has been described that the screw N3 fixing the Y slide rail 12 and the bracket 16 is removed when the embroidery frame 6 is removed (see FIG. 7). The screw N2 that secures the X-ride rail 15 and the bracket 16 may be removed (see Figure 8). When removing the screw N2, it will be necessary to remove the screw with a downward force, but in any case, it is easy to do this because it is at the front of the sewing machine.

 Further, in the above-described embodiment, the force described for the example in which the ride rail 15 that is also a two-stage channel member is provided as a member that supports the embroidery frame 6 at the front end portion of the embroidery frame support device 7. Instead of the rail 15, a linear rail (a rail and a slider that engages with the rail) may be used, the rail may be provided on the lower surface of the front end of the embroidery frame 6, and the slider may be provided on the bracket 16. In short, it is only necessary that the embroidery frame 6 and the bracket 16 move integrally in the Y direction and the embroidery frame 6 moves relative to the bracket 16 in the X direction.

 [0037] In addition, a bag frame can be used instead of the embroidery frame 6. In this case, instead of the ride rail 15, a support member capable of mounting the front end of the bag frame (moves integrally with the bag frame in the Y direction and allows sliding of the bag frame mounted in the X direction). It is good to attach what is possible. In this case, since it is not necessary to replace the Y slide rail 12, it is very easy to replace different types of embroidery frames.

 In the present invention, supporting the free end of the embroidery frame is not necessarily limited to strictly supporting the free end (tip) itself of the embroidery frame. Now that I support the part of!
