CAMERA
Document Type and Number:
Japanese Patent JP3467661
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent assembly from being performed in a state where a rotary shaft on a front surface side is mistaken for a rotary shaft on a back surface side by setting either of the outside diameter or the length of the rotary shafts to different size.
SOLUTION: The rotary shafts 131a and 131b are provided on the front surface and the back surface of a sprocket 131 having teeth whose front surface and back surface have different shape, respectively, and a charge cam 133 is integrally constituted with the sprocket 131. The outside diameter size of the rotary shafts 131a and 131b is different and the length thereof is the same. The rotary shafts 131a and 131b are inserted in holes formed on a camera main body 101 and fit therein with proper clearance. Therefore, the sprocket 131 can not be inserted in a state where the front surface side and the back surface side are reversely turned. Thus, even in the case of using the sprocket whose front surface and back surface have the different shape, the assembly is not performed in a state where the front surface is mistaken for the back surface.
