Abstract: A sewing machine includes a coordinate indicator, a processor, and a memory. The coordinate indicator includes a cylindrical housing, a rod-shaped indicating member, a switch, a single transmitter, a receiver, and a flat surface. The memory is configured to store computer-readable instructions. The computer-readable instructions, when executed by the processor, cause the sewing machine to perform processes that include computing a plurality of sets of first coordinates based on a plurality of times at which the receiver receives a ultrasonic wave, computing a movement direction based on at least some of the computed plurality of sets of the first coordinates, computing a movement distance based on at least some of the computed plurality of sets of the first coordinates, and computing second coordinates based on at least some of the plurality of sets of the first coordinates, the movement direction, and the movement distance.

Abstract: A coordinate computation device includes a position indication portion, a detection portion, a processor, and a memory. The position indication portion includes an indicating portion, a switch, and a transmitter. The detection portion is configured to detect ultrasonic waves transmitted by the transmitter. The memory is configured to store computer-readable instructions. The computer-readable instructions cause the processor to perform processes that include computing sets of first coordinates, based on times when the detection portion detects the ultrasonic waves, computing a movement direction of the position indication portion on a plane, computing an angle formed between the plane and a direction in which the position indication portion is long, and computing a set of second coordinates, based on the computed movement direction, the computed angle, and a set of third coordinates among the sets of the computed first coordinates.

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.
