Patent ID: 7473856

Claim:
A stored material detecting switch comprising: a hollow case; stored material detecting means, accommodated in the case, for outputting a detection signal when the case is inclined at an angle to or greater than a predetermined angle; flexible suspension means for suspending the case in a storage chamber; and moving means for moving the case in the storage chamber by moving the suspension means, wherein the detection signal is outputted from the stored material detecting means at a time when the case is inclined at the angle equal to or greater than the predetermined angle through contact with a stored material in the storage chamber being used to detect a storage level in the storage chamber, wherein the moving means comprises a rotatable rotary plate, and a fulcrum member provided on the rotary plate at a position that is offset from the rotational axis of the rotary plate, the fulcrum member slidably supporting the suspension means and rotating together with the rotary plate when the rotary plate is rotated.
