DATA BACK DEVICE FOR BACK FOCUS CONTROL TYPE AF SINGLE LENS REFLEX CAMERA

摘要

PROBLEM TO BE SOLVED: To provide a data back device for a back focus control type AF single lens reflex camera capable of imprinting data with quality as in the conventional manner, removing adverse effect on an AF control function at the time of inputting data by an operation button, and equipped with a mechanism preventing external light entering between a circuit module and a back cover by providing a movable body with the circuit module. SOLUTION: A multi-module 22 is mounted on the back surface of a pressing plate base 5. An imprinting part 29 is always kept constant with respect to a film surface. A button operating part 30 is arranged on a back cover 47 side and connected to the multi-module 22 through a flexible printed circuit board 40. One end of square pole-like light shielding rubber 4 is fixed on the end 27a of the module cover 27 of the multi-module 22 and the end 47a of the back cover side so as to prevent the external light from entering.
