The distributor 136 distributes the reagent to each nozzle 131, and five branch hoses 138 are branched from the body. In this embodiment, since the nozzle unit 130 includes five nozzles 131, the distributor 136 is formed such that the five branch hoses 138 branch, but the distributor 136 is based on the number of the nozzles 131. The number of branch hoses 138 branching from may also be added or subtracted.

In addition, the branch hoses 138 branched from the distributor 136 are all spaced apart by the same distance from the center of the body of the distributor 136, the length of each branch hose 138 is also the same. Therefore, when pressure is applied for dispensing or dispensing the reagent, the same amount of reagent is supplied to the dispensing hoses 138 to induce the same amount and pressure of the reagent supplied to each nozzle 131.
