Abstract

PURPOSE: To prevent the breakage of a countactor owing to the convex part on the interchangeable lens side by retreating the contactor for lead-in of lens information during mounting of the interchangeable lens.
CONSTITUTION: When an interchangeable lens 1 is mounted, its lock pin 13 is pressed and therefore a control lever 19 rotates counterclockwise. As a result, an information lead-in lever 15 is rotated clockwise against a spring 16 by way of a pin 15a. Hence, a contactor 15c retreates to ouside the locus of the convex part 4 of the lens 1 and the convex part 4 passes there without interfering with the contactor 15c. After the rotation of a predetermined angle, the pin 13 falls into a locking hole 6. The lens 1 is then mounted and the contactor 15c contacts a signal transmission member 5. Since in this way the contactor 15c is mounted without interfering with the convex part 4 of the lens 1, the breakage of the contactor 15c may be prevented.
