An automatic coating apparatus which is arranged to guarantee higher operational reliability, particularly to preclude coating defects as caused by malfunctioning of a cartridge gripper ( ) or by the use of an non-replenished or deficiently replenished paint cartridge. A cartridge gripper assembly ( ) is constituted by a gripper member ( ) with gripper claws for gripping a paint cartridge ( ), a grip detector switch ( ) which is adapted to detect whether or not the paint cartridge ( ) is securely gripped by the gripper. ( ), and a replenishment level detector switch ( ) which is adapted to detect whether or not the paint cartridge ( ) is replenished with paint to a predetermined extent. Therefore, as the paint cartridge ( ) is gripped by the cartridge gripper ( ), the grip condition on the paint cartridge ( ) can be monitor by the grip detector switch ( ). At the same time, a replenished paint level within the cartridge ( ) can be monitored from outside by the replenishment level detector switch ( ).
