Light modulating light emitting device of grip form

Abstract

Abstract PURPOSE: To improve the portability of the device and the operating characteristic of the camera and prevent the failure of the light emitting part by forming the box of the light modulating light emitting device in grip form and mounting the light emitting part to the camera body. CONSTITUTION: When a light emitting device 10 is mounted to a camera body 1 by means of a screw 12 and a screw hole 3, a protrusion 6 fits in the recess 14 of the box 10 and the switch SW 1 of the circuit is changed over from b to a by a contactor 15 and a cell 20 is opened from the circuit. As a trigger button 13 is depressed, the connection terminals T 1 , T 2 of the box 10 are connected to the terminals T 3 , T 4 on the camera side and a switch SW 2 also closes. When the trigger button 13 is depressed, the switch SW 2 closes and an electromagnetic trigger circuit 23 operates to perform shutter release. At the mounting of the box 10, the switch SW 3 is closed by the depression of the release button 5. COPYRIGHT: (C)1980,JPO&Japio
