The idea of chaotic deformed microcavities has been suggested to make a directional emission with keeping the cavity-Q factor higher than conventional cavities. We realized the chaotic deformed microcavity with a liquid jet system, and analyzed the directional emission of it numerically and theoretically. In this work, we present a experimental and numerical evidence of the turnstile process which is realized in the double peak of the deformed microcavity emission. Interestingly, this characteristic emission is not consistently explained by the classical turnstile process in the whole regimes of a chaotic transition. Accordingly, we suggest the distinguished emission mechanism depending on the action transport in the classical phase space.
