PURPOSE: An inkjet printer head monitoring apparatus is provided to measure a plurality of ink droplets at high speeds by a rotation of a rotary mirror unit because the rotary mirror unit changes an optical path between a photographing member and the ink droplets by a rotation. CONSTITUTION: An inkjet printer head monitoring apparatus comprises a plurality of filming units(210), a plurality of rotary mirror units(240), a transferring stage(220), and a controlling unit. The plurality of photographing units obtain images by taking photos of an ink droplet(120). The photographing member takes a photograph of the ink droplet reflected to the rotary mirror units. The rotary mirror units are installed in an optical path between the photographing member and ink droplets by respectively corresponding to the photographing units. The transferring stage moves the plurality of photographing members together so that a length of the optical path is regularly maintained. The optical path is a path from the photographing member to the ink droplets through the rotary mirror unit. The control unit controls an operation of the rotary mirror unit and transferring stage.
