Abstract: A embroidery machine 2 has a first arm 3R in which a part of an embroidery frame 1 may be held, and a second arm 3L projecting in the same direction as the first arm, and in which another part of the embroidery frame 1 may be held. A long guide holding part 5 as extends in a direction to intersect with the direction by which the first arm 3R and the second arm 3L project. At least one of the first arm 3R and the second arm 3L can slide on the long guide holding part 5 such that a spacing M between the first arm 3R and the second arm 3L may be varied. A releasable fixing device is mounted to releasably fix at least one of the first arm and the second arm in at least one desired position on the guide holding part.

Abstract: A sewing material holding device 2 in a sewing machine includes a first arm device 3R and a second arm device 3L and makes it possible to hold a sewing material 1 temporarily. At least one of the first arm device 3R and the second arm device 3L has a main arm 32 protruding in a direction, a sub arm 33 protruding along the main arm 32 and capable of cooperating with the main arm 32 to hold the material, a pressure contact device 90 for establishing a pressure contact between a part of a protrusion edge 33f of the sub arm 33 with a protrusion edge 32f of the main arm 32 while defining a clearance 92 between a base end portion 32r of the main arm 32 and a base end portion 33r of the sub arm 33, the pressure contact between making it possible to hold the material temporarily, and a clearance reduction device 91 for enhancing a degree of holding the material by engaging one of the main arm 32 and the sub arm 33 to the other.

Abstract: A thread consumption detecting apparatus includes an axial supporting shaft, a detector lever, a torsional spring, a proximity sensor, and a central processing unit (CPU). The detector lever includes an intermediate portion, a loop-shaped thread-contact end, and a base end. The intermediate portion is fitted idly around the supporting shaft so that the detector lever can swing. The thread-contact end is disposed so as to pass a thread outside the loop-shaped portion. The base end is detected by the proximity sensor. A swinging stroke of the detector lever is disposed so as to interfere with a thread-transfer-route variation range resulting from a fluctuation in tension of the thread. The torsional spring urges the detector lever in one swinging direction. The proximity sensor detects the base end on approach when the detector lever is swung by the tension of the thread. The CPU judges whether the thread is consumed or not in accordance with a signal output from the proximity sensor.
