Description

[Brief explanation of the drawing]

Fig. 1 and Fig. 2 relate to an embodiment of the present invention, Fig. 1 is a perspective view of the sewing machine, Fig. 2 is a view taken in the direction of arrow G in Fig. 1, and Fig. 3 shows the front cloth guide surface of the auxiliary bed. This is a diagram aligned with the extended surface of the upper surface of the free arm bed. □This is a diagram for comparison with Figure 2. 1 is the sewing machine, 2 is the upper arm, 3 is the needle bar,
4 is an upright body part, 5 is a free arm bed, 6 is an auxiliary bed, A is a front cloth guide surface, F is an extension of the upper surface of the free arm bed, N-N is the reciprocating direction of the needle bar, K is a tangential plane, Y
-Y is a vertical line.

Claims (1)

[Claims for Utility Model Registration] 1. An upper arm of a sewing machine, in which a needle bar is slidably guided in a direction of 1,000 axes, and the needle bar is guided in a reciprocating direction together with the upper arm and a vertical body connected to the upper arm. The upper part of the free arm bed is tilted at an angle α to the rear with respect to the vertical line, and the extended surface of the upper surface of the free arm bed, on which the auxiliary bed is detachable, is tilted while maintaining a relationship substantially perpendicular to the direction of the reciprocating motion. , and a sewing machine characterized in that the front cloth guide surface of the auxiliary bed is vertically moved downward from the extension surface near the front edge. 2. The sewing machine according to claim 1, wherein the tangential planes of the lower surfaces of the vertical body and the free arm bed are orthogonal to the direction of reciprocating movement of the needle bar.
