Claims

[Scope of Claim for Utility Model Registration] (1) A photometric circuit, an ISO sensitivity output circuit, a means for determining whether to perform flash photography or constant light photography based on signals from both circuits, and a flash device. means for detecting whether the charging voltage of the main capacitor has reached a predetermined value; a switch means for outputting a release signal; and a means for outputting a light emission start signal for the flash device;
a release means for starting an exposure control operation; a means for selecting between a continuous shooting mode and a single frame shooting mode;
When the selection means selects the single-frame shooting mode, the decision means decides flash shooting, and the detection means detects that the charging voltage has not reached a predetermined value, the release signal from the switch means is sent to the release means. In addition, in the continuous shooting mode, the release signal is transmitted from the switch means to the release means every time the shooting operation is completed, and in the single frame shooting mode, the release signal is transmitted from the switch means at the end of the shooting operation. A first gate means transmits only a release signal that is output again after the flash is no longer output, and a selection means selects a single-frame shooting mode and transmits a light emission start signal to the flash device only when the deciding means decides flash shooting. 1. A camera having a continuous shooting mode, characterized in that it is equipped with a second gate means for transmitting information to the camera. (2) The camera according to claim 1 of the utility model registration claim, further comprising means for issuing a warning when the determining means determines flash photography and the selecting means selects continuous photography mode.
