Instead, a simple multi-stage sewing switch is used to respond to the multi-stage partial sewing. [Prior art] prior art, there already exist on the thickness detected automatically, the amount of delivery vehicles suture cloth or fabric corresponds to the thickness of the push amount is changed fabrics, particularly with respect to the patent detecting means of the thickness of the cloth Several pieces exist. For example, "Patent Document 1" Japanese Patent Laid-Open 5-16177 1, "Patent Document 2" Japanese Patent Laid-Open 5--24528 3, "Patent Document 3" Laid-Open 10--23 No. 5 0 5 8 and "Patent Document 4" JP-A No. 10-2 3 5 0 5 9. SUMMARY OF THE INVENTION In the above Patent Document 1, when the presser foot tongue portions across the edge section or detention cloth, fabric thickness change detecting means may be detected in the thickness of the cloth, and the presser foot to reduce stress and increase push sublingual charge The amount is used as a control device.

Patent Document 3, in the front and rear portions of the seam portion, and the thickness of the cloth needle position under the detection position, even if the thickness of the cloth have great differences, may be set to an appropriate line feeding amount Feng vehicle at the present position under the needle. In Patent Document 4, the position of the tongue is not affected.

200 411 101 page 5 V. Description of the Invention (2) thickness of the cloth can be detected with high accuracy. Multi-segment sewing refers to an operation in which the upper portion connected with the flat portion and the portion is usually sewn with the subsequent flat portion. During operation, the change in the sewing point is caused by the change in the thickness of the fabric at the sewing seam, which causes the fabric to be pushed poorly, resulting in the occurrence of poor sewing. Therefore, there have been proposals in the aforementioned prior art, but the properties of the cloth have not been taken into consideration. The previously known cloth thickness detection device only corresponds to the "thickness of the fabric". In fact, when different fabrics are sewn in multiple stages, the workability is not the same. Therefore, the previous technology can not avoid the occurrence of different seam quality in the actual multi-segment sewing. Due to multi-stage portion constituting the cloth overlapped condition, the condition sewn portion has a multi-stage continuous variation, only a single thickness detection, and corresponds to a state that can not be continuously changed. To illustrate this problem, as shown in Figure 9 (a), the individual seam conditions of the upper section (勹) and the normal section (female) of the seam portion are clear. If the seam conditions corresponding to the cloth thickness are understood, that is, good correspondence can be sewn seam portion of the upper part (spoon) and generally portion (female). However, in the case of a multi-segment sewing problem, in particular, a defect that occurs when a normal flat portion of a seam and an upper portion of a continuous seam are jointed, the conventional cloth thickness detection device cannot cope with the sewing conditions. That is, when the cross section (door) of the upper section (勹) of the seam section to be sewn (i.e., the section of the upper section crosses the normal section), the continuously changing offset cannot be detected. As shown in FIG. 9 (b), the inclination of the straddle portion when the thickness of the cloth is changed from a thin portion to a suitable thick portion cannot be detected (slope). The inclination of the straddle will affect the pushing force when pushing the fabric and the rising force of the feet. In order to smoothly press the tongue to press over many seams, the pressure of the tongue must be reduced for the slope of the cross and the specific step size.

Page 6 200411101 V. Description of the invention (3) Therefore, even if there is an effective cloth thickness detection device, the pressing of the ankles cannot smoothly cross the multi-segment joints, which is a major disadvantage. And mounting complicated detecting means to a thickness of the cloth presser foot surrounding the tongue, the machine will increase the price disadvantage. Therefore, simple and inexpensive sewing machine can be sewn multi-function, the hope is for the public. As counted tongue adapted to operate with joints foot, car charge and sewing machine more frequently if unction sewn on to be in, in, an amount set for study based their research Entitlement off operation, push, not related to the material through the sewing machine disposed apart slits, provided the force at that point, by the lack of set Zhang and the bobbin loader, said slit solution sewing in sewing closed car sewn apart summary segment plurality duty vehicle 1 that there is appropriate number of stages receiving Ming has meaning multiple internal The appointed book is issued in the middle and upper parts, and the force plate [lifts and presses the tongue section of the car system, multi-legs, multi-machined push-push, and push-pull with simple sewing materials and a good cloth. amount set by the supply, feeding the pushing means mentioned - portion of formula slit sheets vehicle strand die slot paragraphs lot of cloth sewn car, a vehicle with some force when a section of a multi-sheet charge across species suitable value in a cable any number of slits should be provided for a given vehicle is intended to set the appropriate system, when the slit may be made out ,, sewing off the vehicle in the opening paragraph and often multi-pressure force seam.
