Abstract: A position detection device detects a current positon of a operation member among positions including a predetermined position and includes a detection system that includes a part to be detected and 3N magnetic sensors S. The operation member can move to the positions in N (?3) different directions from the predetermined position. Movement of the operation member between the predetermined position and another position cause outputs from three of the magnetic sensors to be switched. The magnetic sensors of which outputs are switched by a movement of the operation member between the predetermined position and a first position are all different from the magnetic sensors of which outputs are switched by a movement of the operation member between the predetermined position and a second position.

Abstract: A lever input device includes: a lever which is tiltable in a first direction orthogonal to an axis of the lever about the axis due to an operation by a user; a swing arm which engages with the lever and swings along with the tilting of the lever in the first direction and amplifies a displacement amount of the lever at the time of tilting; and a magnet body mounted on the swing arm, wherein the swing arm is elongated along a second direction which is a direction along the axis, is configured such that distance (D13) between a swing fulcrum and a mounting portion of the magnet body becomes larger than distance (D12) between the swing fulcrum of the swing arm and an engaging portion of the swing arm with the lever.

Abstract: A strip matter cutting device for sewing machine is provided which is mainly employed in automatically cutting a tape or rubber sewed on the shoulders of a T-shirt. It is arranged such that the whole of a cutting part which comprises a rotary cutting blade and a tape receiving portion integrally formed with a tape pick-up portion, is shifted between a cutting action position closely adjacent to the rear of a needle location of a throat plate secured to the top surface of a sewing machine bed, and a non-action position at which the cutting part is retracted upward to the left of a sewing machine arm over the throat plate, through a rock arm which is driven to rock reciprocally by a rotary cylinder. Employment of this arrangement permits an improvement in work efficiency and a significant reduction in work burden. Even for a wide object to be sewed, it is fed freely for automatic cutting of a sewed tape or rubber, without the tape or rubber losses.

Abstract: A method and an apparatus for controlling the fabric edge position wherein a fabric fed to the needle location of a sewing machine is fed downstream, feeding distances per unit time at two feeding points, which are along a direction almost perpendicular to the fabric feeding direction, are differentiated by detecting the fabric edge position in the vicinity of the needle location, thereby shifting rightward and leftward the fabric edge position in the vicinity of the needle location so as to form a seam at a constant distance from the fabric edge.
