发明名称 OPTICAL DEVICE
摘要 PURPOSE:To make it possible for a photographer who observes the inside of a finder visual field to easily and surely operate each function without being bewildered by optimumly arranging an index for detecting the line of sight in the visual field of the finder in accordance with every function which is operated at the time of detecting. CONSTITUTION:A finder means is provided with the index 4 for inputting the line of sight in the visual field, and a signal for operating a desired function is formed by a means for detecting the line of sight when it is detected that the line of sight by an observer lies on, or lies near the index 4 for inputting the line of sight. And then, a display part 2 in the finder visual field is arranged along one side of an object image visual field 1, next, the index 4 for inputting the line of sight is set on a position opposite to an information display part 2 with range finding vidual field frames 3a-3e interposed, so that only when a finder observer intentionally observes the part near the index 4 for inputting the line of sight, a diaphragming operation is started. The diaphragming operation is released after a prescribed time passes. And also, it is allowed to display a photographing condition adjacent to the inside edge of the visual field 1.
