1. A sieving device comprising:
a mount;
a vibration unit configured to perform reciprocating vibration relative to the mount in one direction in plan view and including a sieve frame;
a first sensor unit, in the vibration unit, including a vibration-unit acceleration sensing unit capable of sensing acceleration of at least the vibration unit; and
a vibration state measurement unit configured to measure a vibration state of the vibration unit based on the acceleration of the vibration unit, which is sensed by the first sensor unit, wherein
the mount includes a second sensor unit including a mount acceleration sensing unit and a mount angular velocity sensing unit, the mount acceleration sensing unit being capable of sensing acceleration of the mount, the mount angular velocity sensing unit being capable of sensing angular velocity of the mount, and
the vibration state measurement unit measures a vibration state of the mount based on the acceleration and the angular velocity of the mount, which are sensed by the second sensor unit.
