Claims

[Claims for Utility Model Registration] Stitch forming means in which the needle and the object to be sewn can be moved relative to each other so as to change the needle drop position of each stitch on the object to form a desired sewing pattern.2. 28, a first storage means ROM which stores in advance data of values corresponding to each needle drop position of the sewing pattern for each data group corresponding to a plurality of sewing patterns of different types in the order of stitches, and a switching operation. a selection means for selecting and activating two desired sets from among the data groups stored in the first storage means in connection with the data group; and a signal that alternately changes to one or the other of the two states at predetermined intervals. and a timing control means for generating the timing control means, and synchronizing each data of two sets of data groups which act in conjunction with the switching operation of the selection means and are activated in response to a change in one state of the signal of the timing control means. A first reading means for sequentially reading out the data in the first storage means, a second storage means RAM capable of sequentially writing the read data of the first storage means, and a second storage means arranged between the second storage means and the second storage means for reading the data. holding the two sets of data, comparing the data values of both data values, and writing only one of the data values into the second storage means in relation to the opposite change in the signal of the timing control means. data comparison means; pulse generation means 22 and 23 for generating timing pulses in relation to one rotation of the sewing machine main shaft; and sequential reading of data written in the second storage means in relation to the timing pulses of the pulse generation means. A pattern sewing device comprising: a second reading means; and driving means A, B for operating the stitch forming means so that the needle drop is performed in accordance with the data value of the data read from the second storage means. sewing machine.
