Abstract
A waste fluid quantity measuring device can comprise a waste fluid tank for recovering a waste fluid, a placement platform on which the total mass of the waste fluid tank acts, a motive force portion for moving at least a portion of the placement platform from a first position to a second position, with a constant force. A sensor can measure a position of the placement platform and a measuring portion can move the placement platform and measure a movement time of the placement platform to the second position, based on a measurement result by the sensor. An evaluating portion can evaluate a state of storage of waste fluid of the waste fluid tank based on the movement time measured by the measuring portion and a correspondence of the movement time and the quantity of waste fluid within the waste fluid tank.
