ABSTRACT:
A quantitation setup mechanism (58) is composed of a piston (62) which is incorporated into a quantitation tank (61) to define therein a metering chamber (63), a quantitation setup portion (65) for presetting a quantity of paint replenishment, and a sensor (66) adapted to detect a displacement of the piston (62) preset by the quantitation setup portion (65). In this instance, paint is replenished into a paint chamber (19) of a cartridge (16) by means of a paint feed mechanism (32). In the course of the paint replenishment, an equivalent amount of an extruding liquid is displaced and discharged from an extruding liquid chamber (20). The displaced extruding liquid is introduced into the metering chamber (63) of the quantitation setup mechanism (58), detecting a quantity of displacement of the extruding liquid by replenished paint by the sensor (66) through the piston (62) to exactly quantitate the paint replenishment.
