The production of a kaon pair ($K^+ K^-$ and $K^0_S K^0_S$) in two-photonprocesses has been measured using the Belle detector at the electron-positroncollider KEKB. We have obtained the invariant-mass distribution of theprocesses between 1.3 and 2.3 GeV. A broad bump structure around 1.7 GeV in the$K^0_S K^0_S$ channel is confirmed, while, in the $K^+ K^-$ channel, a bumpstructure is seen near 1.9 GeV. The angular distribution of the final-statekaons is analyzed to explore the spin(-helicity) structure in eachinvariant-mass region for the two processes. Contributions from existing andpostulated resonances are discussed.Comment: 4 pages, Proceedings of the 4th International Conference on B Physics  & CP Violation, Ise-Shima, Japan, February 19 - 23, 200
