The Ricoh Teleca 240 is a binocular half frame camera with fixed lens made in Japan by Ricoh from 1971. This was a joint project with Nichiryo International Corporation Ltd.: the Nichiryo Nicnon and Nichiryo Teflex are nearly identical. This was a pair of binoculars with a Ricoh Auto Half E attached to one of the binocular lenses. A beam splitter in the binoculars diverts the image to the camera. Ricoh Auto Half E selenium cell and optics were removed, so this one does not operate automatic. Measure was possible with an optional separate lightmeter.
