Title: Power source control circuit of flash device
Inventor: YAMADA MASANORI
IPC: H02J1/00
Filed: 1978-11-27
Abstract: PURPOSE: To improve the operating characteristic of strobe device and prevent the breakdown of a converter owing to high voltage application by disabling the converter in cooperation to mounting of an extermal power source.  
     CONSTITUTION: When a plug 14 is inserted into the recess 15e of a plug socket 15, first the ground wire E of the strobe connects to the negative electrode of a layer-built dry battery 11 being an outernal power source by way of electrodes 15b, 14b and switch 13. When the plug 14 is pushed further, the electrodes 15c, 14c connect and therefore the base of a transistor Tr 18 connects to the ground line E and goes ON, causing the emitter and base of a Tr 13 to short. As a result, a Tr 13 goes OFF and oscillation of a DC-DC converter stops, thus there is no more consumption of the SUM 3 dry battery 1 being the internal power source. Further when the plug 14 is pushed in, the electrodes 15a, 14a make contact and the one electrode of a capacitor 8 connects to the positive electrode of the dry battery 11 and this becomes the power source to take place of the dry battery 1. Thereby the improvement of operation and the breakdown prevention of the converter owing to high voltage application may be realized.
