SOLUTION: A mechanism 2 for chucking a dispensation head 3 is fixed to the output end of a reciprocal driver 1. A mechanism 5 for controlling the chucking/releasing operation of the chuck mechanism 2 is disposed on the side of each head supporting member 41 of a container 4 containing a spare dispensation head 3. The chuck control mechanism 5 comprises a control piece 54 engaging/disengaging with/from the chuck mechanism 2 to perform chucking/ releasing operation, and a plurality of magnet pieces 81, 82, 8 for driving the control piece 54 reciprocally when the chuck mechanism 2 reciprocates to bring the dispensation head 3 chucked to the chuck mechanism 2 close to the supporting member 41 or separate the dispensation head 3 therefrom. |
