Abstract
PURPOSE: To enable input operation of high precision by simplifying a circuit by digitizing direct and transferring photography information to a camera side.
CONSTITUTION: For example, as distance adjustment ring 1 is rotated, rotating member 4 in the same body with guide pin 2, fit in groove 2 provided in the internal surface of ring 1, rotates through pin 2. Consequently, contact piece 7 pressed against the surface of code plate 6 fitted to the surface of member 4 transfers a digital value, which corresponds to a set distance, to a camera body side. A set aperture valve, etc., are the same and the simple constitution requiring no A/D converter, etc., transfers the set value digitally to provide the input transfer of photography information with high precision, so that proper exposure can be calculated and determined.
