PROBLEM TO BE SOLVED: To provide a dispenser in which the dispensation head can be replaced automatically and quickly. SOLUTION: A reciprocal driver 1 is fixed, at the output end thereof, with a mechanism 2 for chucking a dispensation head 3. A mechanism for controlling the chucking/releasing operation of the chucking mechanism 2 is disposed on the side part of a container for container a dispenser head 3 to be replaced. The chucking mechanism 2 comprises a plurality of chuck claws 23 for clamping the dispenser head 3, and a slide tube 22 for opening/closing the plurality of chuck claws 23 as the chucking mechanism 2 is driven to reciprocate through the reciprocal driver 1. The chucking mechanism 2 is connected with a first sensor 203 for detecting the state where the dispenser head 3 is jointed to the chucking mechanism 2, and a second sensor 302 for detecting the state where the slide tube 22 closed the plurality of chuck claws 23. |
