Abstract

PURPOSE: To enable the flash device to be controlled even if a sensor adapter is connected by mistake by connecting the adapter to a photoelectric element when it is mounted to the flash device and providing electrodes for making contact to photometric signal transmission electrodes to said adapter.
CONSTITUTION: When a sensor adapter 7 is mounted to the mounting jig 15 of a flash device 13 and a flash adapter 11 to the accessory shoe 5 of the camera respectively, the switch depressing member 7m of the adapter 7 is pressed by the pin 15m of the mounting jig 15. Then, the traveling contact piece 7QA connecting to the collector of the photo transistor 7a of a signal changeover switch 7Q connects to the stationary contact 7QC connecting to the stationary contact 7PC which connects to a photometric signal transmission electrode 7n. On the other hand, the changeover switch 7P is not depressed and therefore the traveling contact piece 7P connecting to the photometric signal transmission electrode 11n of the adapter 11 connects to the stationary contact 7PB which connects to the stationary contact 7QB. Hence, even if the adapters 7, 11 are mounted by mistake, the flash device 13 may be controlled.
