CONSTITUTION:A storage means MC storing a plurality of sewing data, a plurality of switches 10(SW1-SW5) corresponding to each sewing data, and readout means reading out the sewing data from the storage means corresponding to the on-state of each swich, are provided. Further, a switching means which can interrupts individually between the readout means and each switch and a control means which activates the swiching means so that if one switch at on-state at the application of power supply is still at on-state regardless of switching of other switches to on-state they are interrupted, are provided. |
