Daytime flash pohotographing device
专利汇可以提供Daytime flash pohotographing device专利检索，专利查询，专利分析的服务。并且PURPOSE: To make possible aperture-priority daytime flash photographing by providing a manual aperture adjusting means which interlocks to an aperture adjusting means.
CONSTITUTION: A changeover ring 24 which has a protrusion engaging with the protrusion 8d of an aperture device 8 and is inscribed with the mark A indicating the set positions for automatic exposure control photography by natural light and second-time-priority daytime flash photography as well as the numberical values corresponding to aperture values is provided. Then, when the changeover ring 24 is manually set in the place of the aperture value corresponding to the desired subject depth and the TA of the second-time changeover ring 25 in the position of the index 25a, then the aperture device 8 is adjusted to the aperture value set to the changeover ring 24 and the traveling contact of a switch S13 is connected to the S13M side, as a result of which an ammeter M2 becomes non-operating and the travelling contacts of switches S14, S15 maintain the state of being held connected to the S14A, S15A side. When a release lever 6 is depressed, flash is generated for the time corresponding to the aperture value, film sensitivity and distance up to the main subject having been set in resistors RFV, RA, RD in the manner similar to the case of the second time priority of electric shutter.
