構造である。(Prior Art) Regarding the first example of a cloth edge cutting device of this type of sewing machine that has been used conventionally, a swinging arm attached to the needle bar of the sewing machine swings as the needle bar moves up and down. When the lever member is moved, the lever member connected to the swinging arm moves up and down using the pivot point with the support member as a lever fulcrum, and the upper knife attached to the end of the lever member also moves up and down at the same time, causing the upper knife to move up and down. It has a structure in which the edges of the fabric fed into the upper and lower knives are cut by working together with the lower knife blade formed at the end of the base plate facing the upper and lower knives.

There is a sewing machine fabric edge cutting device described in the issue. .
This cutting device has a fixed blade, a movable blade, a guide piece, etc. mounted on a long and thin L-shaped mounting plate, and these are placed on the upper surface of the throat plate on the sewing machine bed using a conventional presser foot. It is attached and fixed as a unit to the lower end of the presser bar using the same method. The L-shaped mounting plate has a narrow horizontal mounting part and an elongated vertical mounting part, and the front side is formed into a long and narrow L-shape, and a presser foot is fixed to the outside of the vertical mounting part of the mounting plate. A mounting piece for the sewing machine presser bar is integrally formed in a part of the sewing machine.

ツド上に正しく配置するように押え棒に装着する
のは手数を要し、特に布ガイド片が存在するため
に、この装置の位置ぎめは一層困難となる。(Problems to be solved by the invention) In the above-mentioned first conventional example, when attaching the cloth edge cutting device to the sewing machine, the swinging arm is screwed to the needle bar, and at the same time, the entire device is not moved to the sewing machine bed. However, taking into account the relationship with the fabric guide piece installed close to the upper knife, the fabric is moved forward of the upper knife (in the fabric feeding direction) in cooperation with the feed dog. The position of the fabric presser foot, which consists of a presser foot and a presser foot for feeding while pressing, must be considered, so make sure that this fabric presser is placed correctly on the sewing machine bed together with the fabric edge cutting device so that it is suitable for cutting the edges of the fabric. The attachment to the presser bar is laborious and the positioning of this device is made even more difficult, especially due to the presence of the fabric guide piece.

に配置しても、その位置決めが難しいと共に転倒
し易い。 Furthermore, in the second conventional example, the elongated L-shaped mounting plate consists of an elongated narrow horizontal mounting portion and a relatively high elongated vertical mounting portion,
On the side of the vertical mounting part, there is a presser bar mounting piece, a presser foot, an operating lever, an interlocking lever that engages with the presser bar, a group of stepped screws for attaching a cam to this interlocking mechanism, and a group of springs stretched around this stepped screw. is equipped with many parts such as regulating wire springs, and there is a mechanical balance between the narrow rectangular horizontal mounting part and the relatively high and elongated vertical part to which many of the various parts mentioned above are attached. It cannot be removed and is in a so-called head-holding state, and even if it is placed on the throat plate as an independent component in one movement, it is difficult to position it and it is likely to fall over.

等に問題点があつたために生じる全体の構成上の
欠陥によりものである。 Furthermore, the arrangement of the fabric edge cutting device on the throat plate becomes extremely unstable, and when the fabric is fed under the presser foot and the interlocking lever moves up and down to cut the fabric with the fixed blade and movable blade, The entire cutting device is unstable and tends to shift and fall, especially in the left and right directions. This results in defects such as not being able to cut the desired area smoothly, and in order to compensate for this defect, the operator must always pay special attention to keeping the cutting device in place so that it does not fall over, which increases efficiency. This poses a hindrance to the fabric edge cutting work. In other words, this conventional cloth edge cutting device has a defect in its overall structure due to problems in the shape, combination, etc. of its component parts.

ミシンベツド上での安定配置を達成している。 The purpose of the present invention is to eliminate the above-mentioned defects and provide a fabric edge cutting device that does not fall over and has good stability when placed on the sewing machine bed. Rather than attaching the main components to the side of the vertical mounting section, the main components are mounted on the wide bottom surface of the support arm (corresponding to the bottom surface of the horizontal mounting section in the conventional example), making the fabric edge cutting device stable on the sewing machine bed. placement has been achieved.

る。 The vertical movement of the needle bar 36 due to the driving of the sewing machine is converted into the vertical movement of the swing arm 12. When the needle bar 36 rises, the end fork 32 of the swinging arm 12, which is pivotally supported by the screw 30 on the protrusion 28 of the support arm 4, is pulled up, and at the same time, the other end is lowered, and the screw 1
8. Pull down the first protruding arm 8 of the lever member 2 via the connecting piece 10 and the screw 16. On the other hand, the second protruding arm 20 of the lever member 2 rises in the opposite direction to the first protruding arm 8, and the blade portion 2 of the upper knife 22 is attached to the end thereof.
4 moves upward while contacting the blade portion 42 of the lower knife. Next, when the needle bar 36 descends, the swing arm 12 and other related members move in the opposite direction to the above, and the upper knife 22 contacts the blade portion 42 of the lower knife and descends. Therefore, the edges of the fabric fed below the second projecting arm 20 are sheared by the upper and lower knives. The fabric from which the edges have been sheared is fed below the presser foot 50 in the direction of arrow A in FIG. A seam is formed in the fabric by the upper thread and the lower thread pulled up from the bobbin below the presser foot 50. For fabrics with continuous seams as described above, presser foot 5
Although not shown in the figure, the feed is continuously fed in the direction of the arrow by the action of the feed dog. As for the seams, not only lock stitches but also zigzag stitches can be formed on the edges of the fabric.
