Description of the invention (4) Between the main shaft and the feed cam, there are: a reduction gear mechanism provided between the main shaft and the first output shaft, and the first output shaft and the above-mentioned installation A two-stage deceleration means of a belt-type deceleration mechanism composed of a timing belt for deceleration is mounted across the second output shaft of the feeding cam. According to the present invention having the above-mentioned constitution, since a reduction gear mechanism and a belt type using a timing belt for deceleration are provided between the main shaft and the feeding cam that is linked to the rotation of the main rotation and makes one revolution for each set number of stitches. The speed reduction mechanism of the two stages of the speed reduction mechanism, therefore, by replacing the timing belt and the large and small pulleys in the belt speed reduction mechanism to adjust the speed reduction ratio, the speed reduction ratio of the belt speed reduction mechanism and the speed reduction ratio of the gear mechanism for speed reduction are multiplied. It is also possible to set the reduction ratio of the feed cam to the spindle in a large and diverse range without using large diameter gears. In addition, in terms of the feeding cam, whether it is a revolver according to each set number of needles, that is, a situation where a single leaf-shaped decorative pattern with a single ring number is formed, or a pine-like decorative pattern with three or more ring numbers is formed. In the case of grain, you can just replace the feeding cam with the same diameter and small diameter. When you want to form a pine leaf-like decorative pattern with 3 or more rings, it has not been replaced with a particularly large one as in the prior art. The diameter and the weight of the feed cam are necessary. By providing a two-stage reduction mechanism composed of a combination belt-type reduction mechanism and a gear reduction mechanism between the main shaft and the feed cam, the speed reduction can be easily performed only by simple operations such as timing belt and pulley replacement. In addition to increasing the ratio and making various changes, 尙 before lifting the large-diameter gear and large-diameter cam, it is possible to arbitrarily and 1-scale apply the Chinese National Standard (CNS) A4 specification while miniaturizing the entire device. 210X297 mm) (Please read the precautions on the back before filling out this page) • Assembly · line-7- 518379 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 _____ B7 V. Description of the invention (5) Easily form a circle A number of different pine leaf-like decorative patterns. In particular, 'as a feed cam in the decorative pattern sewing machine related to the present invention having the above-mentioned constitution', as described in item 2 of the scope of the patent application, the link mechanism is swung during the rotation according to the specified number of stitches. The ideal number of times is 2 to 6 times. Those who can perform the cloth feeding movement by the feeding teeth for many times, and the necessary feeding amount between the pine leaf-like decorative patterns. The lever mechanism and the feeding teeth are required to move forward and backward. Compared with those who achieve a slewing motion of the mechanism, it is more likely to reduce the unit movement amount of the link mechanism and the forward and backward movement mechanism of the feeding teeth. As a result, it is possible to eliminate the interference between the ring top device and the swing mechanism. The speed limitation condition, and even the speed limitation due to the motion inertia, can increase the decorative pattern sewing speed by increasing the rotation speed of the main shaft. In addition, by dividing the cloth into a plurality of times, the loop-shaped stitches can be smoothly separated from the majority of the claws, and the predetermined pine leaf-like decoration can be formed beautifully and stably. In addition, as described in the fourth aspect of the patent application scope, as a mechanism for the vertical movement of the feeding teeth of the decorative sewing machine with the above structure, the feeding base is provided with a feeding base system that can be moved up and down with the fulcrum of the forward and backward movement mechanism of the feeding teeth as the center Or one of the two, as described in item 5 of the scope of the patent application, which has a feed base system that can be moved up and down with the action point of the forward and backward movement mechanism of the feed teeth as the center. Both of them are feasible, but if the structure that uses the action points of the forward and backward movement mechanism of the feeding teeth to make it move up and down, it can reduce the number of parts and reduce the cost.
