Abstract: A feed dog drive motor and an X-direction motor are connected to common input/output ports of a CPU via first and second driver IC circuits, respectively. In response to a drive switching signal generated from the CPU, selected one of the first and second driver IC circuits is enabled, causing the feed dog drive motor and the X-directional motor to selectively energize. A common driver IC circuit can be used in place of the first and second driver IC circuits. With such a configuration, the number of input/output ports of the CPU as well as the number of driver IC circuits can be reduced.

Abstract: A noise canceling circuit that eliminates noise from an AC current of an AC power supply is provided with a changeover device that brings the noise canceling circuit into and out of conduction with a secondary side of a transformer in accordance with an on-off state of a switch. The noise canceling circuit includes a filter portion. The changeover device may be a relay or triac.

Abstract: Disclosed is an embroidery data processing device having a displaying device which displays an image of an embroidery pattern, and an indicator which indicates a color of a thread to be used for forming the embroidery pattern displayed on the displaying device. The displaying device can be a conventional monochrome LCD, and the indicator indicates the color of the thread by emitting light having the same color of the thread.

Abstract: A sewing pattern display device including a display for displaying a plurality of options relating to sewing; a transparent touch panel disposed adjacent to the display and capable of detecting a position where the touch panel is pressed; and a control device for determining, based on detection by the touch panel, a position of the display corresponding to a pressed position of the touch panel and, when the touch panel is pressed to simultaneously indicate more than one of the options, processing an option different from the indicated options.
