To provide a discharging device for marking by which a trademark or the like is automatically marked on a material to be coated by a piezoelectric element-driven diaphragm pump.
A diaphragm pump 1, and a device which a paint bag 2 for feeding marking material such as paint 2 and the diaphragm pump 1 are planarly connected and integrated into one body to form are housed in a vessel- like frame body 3 to form a discharge device for marking. The diaphragm pump 1 consists of two diaphragm pumps made of glass arranged opposite to each other in a pump house and is equipped with a suction valve and a discharge valve. The paint bag 2 connected to the diaphragm pump 1 is a solvent resistant transparent bag. A suction pipe 4 connected to a suction port of the pump 1 is airtightly inserted into the paint bag 2, and the paint bag 2 is planarly mounted on the frame body 3. And a discharge nozzle of the diaphragm pump 1 is provided with a nozzle cover 21 with a washing hole, and a suction pipe frame 22 and a bag pressing guide 23 for preventing the bubble from being suctioned are arranged in a supply mechanism.
