Abstract
PURPOSE: To prevent a malfunction caused by an electrical noise mixed in by a method wherein a position of a tube is detected by a photochemistry seesaw in which a volume change of a solution caused by irradiation of light is made use, and a light signal operates the actuator.
CONSTITUTION: The actuator operation signal is fed from a controller 13 according to an input signal of a sensor. When a light emitter 12 is controlled by the actuator operation signal to transmits the light signal through an optical fiber 11 and to permit the same to be irradiated to the photochemistry seesaw 1 through a light projection window 10, the photochemistry seesaw 1 is driven and the position thereof is detected by a fluid element approach switch 8 and an output air pressure of the approach switch 8 is led to a fluid logical element to carry out operations and to enable a driving means to be operated. Accordingly, the operation signal is transmitted to the actuator by means of light and the actuator is directly operated without depending upon an electrical means, so that no malfunction is caused by the electrical noise mixed in.
