Document Type and Number:
Japanese Patent JP3530230
Kind Code:
B2
Abstract:
PURPOSE: To surely switch the shielding of the shield plate of a shutter mechanism in stopping by using the driving of the shutter mechanism during an exposure, even if an exposure interval is short.
CONSTITUTION: In a shutter unit 22, two shutter mechanisms 23 and 24 having four left and right shutter aperture lines in two upper and lower stages, that is, eight in-total are provided side by side, respectively. Each of stepping motors 49 and 50 is alternately driven to rotate the shutter disks 32-39 of two sets of each four pieces twice in each rotation and expose the images of 16 frames time sequentially. The shield plate 58 of one shutter mechanism 23 or 24 is moved in liaison with the drive of the stepping motor 49 or 50 of the other shutter mechanism 23 or 24 and the shielding of the shutter aperture lines of one shutter mechanism 23 or 24 is switched in the upper and lower stages, in the first and second rotations of the shutter disks 32-39.
