PURPOSE:To provide an eject device of multiple tips capable of reducing the operation force for ejection remarkably. CONSTITUTION:A tip ejector plate 2 with multiple surfaces 4a, 4b, and 4c of different height with which the upper ends of tips 3 are made in contact is provided. The tips are not ejected all at once, but ejected progressively one by one (approximately two at the maximum). By this the operational force for ejection is reduced remarkably. Thus the output of a motor for the tip ejector device must not be altered at all even if the number of multiple tips are increased, and the design of an automatization device can be altered easily and also the degree of design can be increased. |
