<P>PROBLEM TO BE SOLVED: To provide a shutter mechanism for cameras having a compact constitution capable of smoothly driving shutter blades in a limited space. <P>SOLUTION: A shutter mechanism for cameras includes: a bottom board 10 including an opening 10a to be an optical path; a plurality of shutter blades 21 to 26 operating to open/close the opening 10a; and a driving source 30 fixed outside the opening 10a in the bottom board 10 to operate the shutter blades 21 to 26. The shutter mechanism for cameras is constituted to store partial shutter blades 24 to 26 of the shutter blades 21 to 26 opposite to the driving source 30 and on the opposite side of the opening 10a, and to store other partial shutter blades 21 to 23 at positions nearer to the driving source 30 than the partial shutter blades 24 to 26. At least one of the shutter blades 21 to 23 stored at the positions closer to the driving source 30 is a driving shutter blade 23 including a driving engaging part 23d for driving the other shutter blades 24 to 26. <P>COPYRIGHT: (C)2012,JPO&INPIT |
