"The activation time for the ring is the same as the casting time for the relevant spell, with a minimum of 1 standard action.
A spellcaster can cast any spells into the ring, so long as the total spell levels do not add up to more than three. Metamagic versions of spells take up storage space equal to their spell level modified by the metamagic feat. A spellcaster can use a scroll to put a spell into the minor ring of spell storing."
If you take this literally it takes you a MINIMUM of 1 standard action to use the ring. No getting around the EXACT wording under the ring listing.
