Then, if the enter key 21h of push key group 21, the middle presser feet height of then setting and determining to be transfused to, and control part 100 should in the presser feet height as in the presser feet order enroll stitch data.And then, presser feet motor 17 during control part 100 drives, presser feet 12 moves to the middle presser feet height that this input has been set during middle presser feet motor 17 makes.
In addition, in the present embodiment, though by pressing enter key 21h, presser feet 12 moved to the middle presser feet height that is transfused to setting during middle presser feet motor 17 made, but be not limited thereto, also can be in pressing numeric keypad 21i input during the presser feet height, presser feet 12 moved during middle presser feet motor 17 made.
Presser feet height during the presser feet order is set in the conduct of position arbitrarily on stitching shape pattern like this, under this state, for example, in the guidance panel 20 that shows stitching shape pattern displaying picture shown in Figure 9, work feed by push key group 21 advance key 21c or work feed back spacer 21d, vernier C is moved along stitching shape pattern, needle falling point in the shape of confirming stitching shape pattern or stitching shape pattern etc. describe to handle the time, if vernier C arrives the position with the corresponding stitching shape of middle presser feet order pattern, presser feet 12 moved to the middle presser feet height that is set during then middle presser feet motor 17 made.
In this Sewing machines M, at the work feed along with the operated key group 21 of push panel 20 advance key 21c or work feed back spacer 21d, when the vernier C of display part 22 demonstrations moves, with the position of vernier C and with respect to the eedle 8 (shank 8a) that keeps frame 11 or the corresponding mode in position of middle presser feet 12, keep the mobile interlock of frame 11 and this vernier C, relatively move with respect to eedle 8 (shank 8a) or middle presser feet 12.
And when vernier C arrival also will be passed through with the position of the corresponding stitching shape of middle presser feet order pattern, as shown in figure 11, presser feet 12 moved to the middle presser feet height that is set during middle presser feet motor 17 made.
Promptly, sewn object in regulation is held under the situation that keeps frame 11, can set up contact and confirms or test to the position of the vernier C in the stitching shape pattern with respect to the configuration of the height of the middle presser feet 12 of the thickness of the reality of this sewn object or ladder difference.As make described middle presser feet move to the control of the height of the regulation that has been set based on stitch data, details carries out based on flow chart shown in Figure 12.
Like this, in Sewing machines M of the present invention, by the operated key group 21 of operating operation panel 20, the input of stitch data that can be used to form the stitching shape pattern of hope is set, and the configuration of the middle presser feet 12 of the optional position of this stitching shape pattern can be set in height arbitrarily.
Especially, because the height of presser feet 12 in can setting by input value, so can one side the concrete size of the height of middle presser feet 12 be shown the height of presser feet 12 in the setting on one side, thus can more easily carry out the setting of the height of middle presser feet 12.
And then, in input is set during the height of presser feet 12, because presser feet 12 moved to the middle presser feet height that is set during middle presser feet motor 17 can make, so the sewn object by will regulation remains in and keeps frame 11, can be to confirming with respect to the configuration of the height of the middle presser feet 12 of the thickness of the reality of this sewn object or ladder difference or testing.
In addition, because based on the stitch data of in Sewing machines M, setting, vernier C is moved along the stitching shape pattern that shows at display part 22, when carrying out relevant the describing of stitching shape pattern with this stitch data and handle (confirming the test of stitching shape pattern), when vernier C arrival also will be passed through with the position of the corresponding stitching shape of middle presser feet order pattern, presser feet 12 moved to the middle presser feet height that is set during middle presser feet motor 17 can make, so, sewn object by will regulation remains in and keeps frame 11, can be to confirming with respect to the configuration of the height of the middle presser feet 12 of the thickness of the reality of this sewn object or ladder difference or testing.
