PURPOSE:To provide the subject apparatus composed of a specific construction and enabling one-touch switching of the mode of shaking motion from outside. CONSTITUTION:The base board 1 of the apparatus is provided with a lower frame 22 of a shaking table in a state freely slidable in the direction Y. A shaking table 16 is placed on the lower frame 22 in a state freely slidable in the direction X to enable the free sliding of the shaking table 16 in X and Y directions relative to the base board 1. The base board 1 is provided with cam followers 8, 14, 15 and the cam follower 8 is engaged in a working slit hole 17 with an engagement restriction part of a switching plate 18 to apply a gyration shaking motion to the shaking table 16. When the cam follower 8 is released and the cam follower 15 is engaged with an engagement restriction rail 33', the shaking table 16 is subjected to reciprocating shaking motion in the direction X. The reciprocating shaking motion of the shaking table 16 in the direction Y is achieved by releasing the cam follower 8 and shifting the switching lever 35 to engage the rail 33' with the cam follower 14. A figure-of- eight motion of the shaking table 16 can be performed by the composition of the motions in X and Y directions.
