Claims

[Claims for Utility Model Registration] (1) In a camera with a built-in electronic flash device having a light distribution characteristic switching means capable of switching the light distribution characteristic of the irradiated light emitted by the arc tube, the light distribution characteristic switching means at least switchable between a first light distribution characteristic that distributes light uniformly over the entire field and a second light distribution characteristic that distributes light to a part of the field, and that indicates the outer edge of the field; a first display section;
A display having a second display section that is switched between a visible state in which the display section is visible and an invisible state in which it is invisible, and which indicates an irradiation area of the irradiation light according to the second light distribution characteristic when in the visible state. and control means for switching the second display section to the visible state when the second light distribution characteristic is selected. (2) In a camera with a built-in electronic flash device that has a light distribution characteristic switching means that can switch the light distribution characteristic of the illumination light emitted by the arc tube, the light distribution characteristic switching means is configured to at least distribute light uniformly over the entire subject. a first light distribution characteristic that distributes light to a part of the field, and a second light distribution characteristic that distributes light to a part of the field that is different from the second light distribution characteristic. a first display section indicating an outer edge of the field;
a second display section disposed within the display section and indicating the irradiation area of the irradiation light according to the second light distribution characteristic; and a second display section disposed within the outer edge display section indicating the irradiation area of the irradiation light according to the third light distribution characteristic. a display means having a third display section; when the first light distribution characteristic is selected, the first display section is made visible; when the second light distribution characteristic is selected, the first display section and the third display section are made visible; A camera with a built-in electronic flash device, comprising: a control means for visualizing the first display section and the third display section when the third light distribution characteristic is selected. . (3) In a camera with a built-in electronic flash device that has a light distribution characteristic switching means that can switch the light distribution characteristic of the illumination light emitted by the arc tube, the light distribution characteristic switching means is configured to at least distribute light uniformly over the entire object field. a first light distribution characteristic that distributes light to a part of the field, and a second light distribution characteristic that distributes light to a part of the field that is different from the second light distribution characteristic. a first display section that is switchable to a third light distribution characteristic, which indicates the outer edge of the object field and in which the outer edge is always visible; a second display section that can be in a visible state that shows the irradiation area of the irradiation light and an invisible state that does not show the irradiation area; a display means having a third display section that can be in a visible state showing the area and an invisible state not showing the irradiation area; and when the first light distribution characteristic is selected, the second display section and the third display section When the second light distribution characteristic is selected, the second display section is made visible and the third display section is made invisible, and when the third light distribution characteristic is selected, the second display section is made invisible. A camera with a built-in electronic flash device, comprising: a control means for making the second display part invisible and the third display part visible.
