Abstract
A printer head for use in an on-demand type ink-jet printer includes a main body which is provided with a nozzle opening, through which ink is ejected to form flying ink droplets, and an ink passage extending to the nozzle opening for storing ink therein to be ejected through the nozzle opening. The printer head includes a pusher unit, which is supported away from the main body and which produces a deflection in response to a print signal supplied thereto, and a connection rod connected between the pusher unit and the main body. Thus, when the pusher unit produces a deflection, which is transmitted to the main body through the connection rod to change the volume of the ink passage, so that the ink inside the passage is partly ejected through the nozzle opening to form ink droplets.
