Noriko Yamamoto (山本紀子 for animator) is two persons:

----------------------------------------------------------------------------------------------------------------------
(keep) 山本紀子 = YAMAMOTO Noriko (animator)
山本紀子 (1996) Case Closed (TV) : In-Between Animation (Studio Boomerang) (livedoor wiki)
山本紀子 (2009) Before Green Gables (TV) : In-Between Animation (Studio Boomerang) (livedoor wiki)
山本紀子 (2009) Detective Conan: The Raven Chaser (movie 13) : In-Between Animation (Studio Boomerang) (Geocities)
山本紀子 (2009) Meitantei Conan Magic File 3 (OAV) : In-Between Animation (Studio Boomerang) (Geocities)
山本紀子 (2009) Saint Seiya: The Lost Canvas - Meiō Shinwa (OAV) : In-Between Animation (Studio Boomerang) (livedoor wiki)
----------------------------------------------------------------------------------------------------------------------
(split) 山本典子 = YAMAMOTO Noriko (seiyuu) (no Wikipedia page, apparently just this minor role)
山本典子 (1983) Aku Dai-Sakusen Srungle (TV) as Secretary (Wikipedia entry of anime)
----------------------------------------------------------------------------------------------------------------------

Perfect source quality made this one really simple. Both given names are fairly obvious, with something like 10 hits in ANN each which are all "Noriko".
