PROBLEM TO BE SOLVED: To reduce the cost and size and to obtain high reliability and quick response by providing digital contactors which extend radially to the entire circumference around the center, and closing a contactor with an external force and generating an operation command. SOLUTION: A spring 27 extends upward through the opening of a printed circuit board 23 fitted to a storage container 10, and a force transducer 26 fitted to the spring 27 engages the conduction path of the printed circuit of the printed circuit board 23 when the spring 27 deviates its center position. Further, the spring 27 extends through the opening 30 of the top surface 11, and a stick 31 is equipped with a conic part 33 coupled with the flat part 34 at the outer periphery engaging the force transducer 36; when the stick 31 is moved, the spring 27 deflects and engages the surface of a conductor 41 formed in the opening of the printed circuit board 23 and the force transducer 36 engages the printed circuit conduction path of the printed circuit 23. |
