There's one automatic exit and two automatic entrance gates in this station. The gate you need is towards your right-hand end of the gate line, though there's a manual gate at each end.
Note, unlike those on the London Underground, the direction of these gates is fixed and there is no ticket slot on the no-entry side. Note also that expired tickets are returned, rather than captured by the machine as you complete your journey.
