Claim:
1. A motion detecting device comprising: an input section to which acceleration signals, that express accelerations of respective axes of three axes of a three-dimensional orthogonal coordinate system, are respectively inputted; and a motion detecting section configured to set each of plural axes, that include two different axes that are selected from among the three axes, as a plurality of designated axes in a predetermined order, and output a motion detection signal upon judgment that directions of motion, that are detected on a basis of the acceleration signals of the respective axes that were inputted to the input section, are directions of respective designated axes that have been set, wherein upon detection that an acceleration signal of an axis has reached both a first threshold value that is set for a positive side and a second threshold value that is set for a negative side, the motion detecting section is configured to detect that motion in a direction of the axis has been carried out, upon judgment that a direction of motion, that is detected on a basis of the acceleration signals of the respective axes that were inputted to the input section, is a direction of the designated axis that has been set, the motion detecting section is configured to generate designated axis detection information and store the designated axis detection information, and upon judgment that a direction of motion, that is detected on a basis of the acceleration signals of the respective axes that were inputted to the input section, is a direction that differs from the direction of the plurality of designated axes that has been set, the motion detecting section is configured to delete the designated axis detection information, and return setting of the designated axis to an initial state.
