Abstract

PURPOSE: To prevent deposition of dust which hinders attraction on iron cores and make the removal of the deposited dust easy and sure by dustproofing the shutter-actuating electromagnetic device with a see-through over.
CONSTITUTION: The portions except the actuating regions of the iron pieces 505d, 605d and iron cores 501, 601 forming the electromagnetic device for controlling shutter opening and closing are held covered with a removable cover such as of transparent plastic material or the like. This constitution prevents deposition of dust on the iron cores during and after assembling of the camera and makes the removal of deposited dust easy and sure, thus the shutter smoothly actuates owing to good attraction of the iron pieces to the iron cores.
