Abstract

1358037 Cameras ASAHI KOGAKU KOGYO KK 19 July 1971 [3 Aug 1970] 56541/73 Divided out of 1355684 Heading G2X In a similar circuit arrangement to that disclosed in Fig.1 of Specification 1355684, in which a camera accessory shoe having an exposed synchronizer contact 3 and a synchro terminal (T 1 or T 2 ), contact and terminal are connected by a diode 5. This arrangement serves the same purpose of reducing electric shock hazard.
