Three-axial acceleration sensor inspection device and method of inspecting three-axial acceleration sensor

1. A three-axial acceleration sensor inspection device for inspecting a three-axial acceleration sensor, comprising:

a test plate for mounting the three-axial acceleration sensor thereon;

a test tray for retaining the three-axial acceleration sensor, said test tray being attached to the test plate;

a sensor supply device for mounting and demounting the test tray on and from the test plate;

a supporting plate for supporting and rotating the test plate; and

a main rotational shaft for rotating the supporting plate,

wherein said supporting plate is arranged radially along a radius direction of the main rotational shaft and disposed at each of at least four locations with an equal angular interval along a circumferential direction of the main rotational shaft, and said sensor supply device is arranged to mount the test tray on the test plate situated at one of the four locations as a first measurement position, and to demount the test tray from the test plate situated at another of the four locations as a final measurement position.

2. The three-axial acceleration sensor inspection device according to claim 1 , further comprising a transmitter mounted on the supporting plate for transmitting an acceleration component signal output from the three-axial acceleration sensor.

3. A method of inspecting a three-axial acceleration sensor, comprising the steps of:

placing the three-axial acceleration sensor on a test tray;

mounting the test tray on a test plate situated one of at least four locations around a main rotational shaft with an equal angular interval along a circumferential direction of the main rotational shaft;

moving the test plate in a specific direction; and

removing the test tray from the test plate situated at another of the four locations.
