<p><P>PROBLEM TO BE SOLVED: To miniaturize a shutter driving device and a camera. <P>SOLUTION: The shutter driving device is configured: to move a front curtain drive lever 141 from an end position to an initial position at the time of reset by a front curtain overcharge absorbing lever 147 which is rotatable on the same axis as the front curtain drive lever 141; at the same time, to energize a front curtain drive spring 145; and to absorb an overcharge at the time of resetting a front curtain light shielding blade group 411 between the front curtain drive lever 141 and the front curtain overcharge absorbing lever 147. Thus, the configuration can contribute to miniaturizing a sequence shutter driving unit 100, a light shielding mechanism 400 and a camera body 1 by eliminating the need to drive the front curtain drive lever 141 and the front curtain light shielding blade group 411 more than necessary when the front curtain light shielding blade group 411 is reset. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
