Title:
ELECTRIC WINDING DEVICE
Document Type and Number:
Japanese Patent JP3270227
Kind Code:
B2
Abstract:
PURPOSE: To make the cost of an electric winding device low and to improve reliability in the driving of a motor for winding film and the stop of the driving thereof.
CONSTITUTION: The motor 14 is driven when a 1st armature 30 which is elastically deformed comes in contact with a 2nd armature 31 which is fixed, the film is wound. The 1st armature 30 is elastically deformed and separated from the 2nd armature 31 when it abuts on any of the cam part 39a of a main switch 39, the cam part 25 of a release link 22 and the projection 40c of a locking lever 40. When main switch 39 is moved to an on-position, the cam part 39a is separated from the 1st armature 30. When shutter release is performed by pushing a release button 5, the locking lever 40 is rotated counterclockwise and the projection 40c is separated from the 1st armature 30. By releasing a finger from the release button 5, the release link 22 is moved to the left and the cam part 25 is also separated from the 1st armature 30, then the 1st armature 30 comes in contact with the 2nd armature 31 so as to drive the motor 14. In the case of completing feeding the film by one frame, the locking lever 40 is turned clockwise and the projection 40c makes the 1st armature 30 deformed to stop driving the motor 14.
