The invention will now be described with reference to the accompanying drawings, wherein like numbers reference like elements.
FIGS. 1A and 1B are perspective views showing a sensor device according to a preferred embodiment of the invention.
FIGS. 2A and 2B are development diagrams of a mounting board provided to the sensor device shown in FIGS. 1A and 1B.
Hereinafter, a sensor device and an electronic apparatus according to the invention will be explained in detail based on an exemplary embodiment shown in the accompanying drawings.
1. Sensor Device
FIGS. 1A and 1B are perspective views showing the sensor device according to an exemplary embodiment of the invention, FIGS. 2A and 2B are development diagrams of amounting board provided to the sensor device shown in FIGS. 1A and 1B, FIG. 3 is a plan view showing an example of an angular velocity sensor provided to the sensor device shown in FIGS. 1A and 1B, FIG. 4 is a perspective view of a pedestal provided to the sensor device shown in FIGS. 1A and 1B, FIG. 5 is a plan view of the pedestal shown in FIG. 4, and FIG. 6 is a perspective view showing the state of fixing the mounting board to the pedestal shown in FIG. 4. It should be noted that the explanation will hereinafter be presented defining the upper side of FIGS. 1A and 1B as the “upper side” and the lower side thereof as the “lower side” for the sake of convenience of explanation. Further, as shown in FIGS. 1A and 1B, three axes perpendicular to each other are defined as an x axis (a first axis), a y axis (a second axis), and a z axis (a third axis), respectively. The z axis is an axis parallel to the normal direction of the pedestal 3, the x axis is an axis parallel to the extending direction of a pair of sides of the pedestal opposed to each other, the y axis is an axis parallel to the extending direction of the other pair of sides of the pedestal opposed to each other in a plan view of the pedestal. Further, the direction parallel to the x axis is defined as an “x-axis direction,” the direction parallel to the y axis is defined as a “y-axis direction,” and the direction parallel to the z axis is defined as a “z-axis direction.” Further, the plane including the x axis and the y axis is defined as an “x-y plane,” the plane including the y axis and the z axis is defined as a “y-z plane,” and the plane including the z axis and the x axis is defined as a “z-x plane.”
