Title:
ONE-ROTATION RESTRICTION MECHANISM IN FILM WINDING
Document Type and Number:
Japanese Patent JP3241988
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a one-rotation restriction mechanism in the film winding, capable of setting the optimum strength of each spring and securing a surer and stabler operation not be directly restricting a release lever with an electromagnet means but by actuating a hooking means with the electromagnet means so as to remove the restrictions of the release lever.
SOLUTION: An attracting plate 2 is released by the energization of a releasing magnet 1 and an MG lever 4 pushes a hooking lever 6 by the energizing force of a spring 30. The release lever 7 is released to turn a restricting lever 8 by a spring 27. A pawl 8b gets out of the groove of a restricting cam and a sprocket on which the restricting cam is fixed is rotatable. When one rotation is made, the pawl 8b jumps into the groove of the restricting cam. During one rotating, the release lever 7 and an MG charging lever 5 are pushed by a release lever cam 9, to charge the springs 27 and 30.
