ABSTRACT:
In a camera, a magnetic control device for controlling a shutter release mechanism or the like includes an electromagnet and a member to be attracted by the electromagnetic. The attracted member is mounted on an axle secured to a control lever. Between the axle and the attracted member, a resilient material is provided for allowing tilting of the attracted member around the axle so that the attracted member can be put into perfect face contact with the attracting face of the electromagnet even if the attracted face of the attracted member is at first not in parallel to the attracting face of the electromagnet.
