Abstract: A focal plane shutter is provided with a switching mechanism having an electromagnet and a stopping member. The stopping member is provided with an engaging portion able to lock an engagement portion provided in a first driving member for a leading edge, and an operating portion wherein a direction of a force, in relation to the electromagnet, switches, in accordance with switching between an application and removal of an electric current in a single direction to the electromagnet, so as to move the engaging portion to a position wherein it is able to release locking of the engagement portion when the electric current is applied, and to move the engaging portion to a position wherein it is able to lock the engagement portion when the electric current is removed.

Abstract: When an imaging apparatus performs normal image-capturing, an energization control unit energizes a driving source to move a body release lever from a locking position to a releasing position, and then does not energize the driving source. When the imaging apparatus performs continuous image-capturing, the energization control unit energizes the driving source to move the body release lever from the locking position to the releasing position, and then energizes the driving source to regulate bounding of the body release lever.

Abstract: A shutter device capable of preventing foreign matter from adhering to an attracting surface of an armature to a yoke, without providing an additional member. In a state of the shutter device assembled to a camera body, an attracting surface of the armature, provided on a drive lever, to the yoke that magnetically attracts the armature extends perpendicularly to a bottom surface of the camera body and is disposed closer to the bottom of the camera body than is a pivotal axis of the drive lever. The shutter device releases the armature of the drive lever from a state attracted and held by the yoke to thereby allow the drive lever to pivot by the urging force of a drive spring, whereby said shutter blade is driven in the direction of closing an opening formed in a base plate.

Abstract: When a blade drive spring has been overcharged when a second cam gear has caused a drive lever to move to a position beyond a position of attraction of an armature by a yoke, a blade lever does not contact the drive lever even if the blade lever has been driven in a direction of opening an aperture by a first blade and a second blade with an urging force of a blade return spring. When the second cam gear has moved to the attraction position form the overcharged position, the blade lever contacts the drive lever before the yoke starts attracting the armature by the attractive force.

Abstract: A focal plane shutter includes: an electromagnet; a board including an opening; blades capable of opening and closing the opening; a drive member holding an iron piece adsorbed to the electromagnet and driving the blades, the drive member being movable such that the iron piece moves toward and away from the electromagnet and being biased by a spring such that the iron piece moves away from the electromagnet; and a holding board facing the board and including a pair of sandwiching portions elastically deformable and holding and sandwiching the electromagnet. The electromagnet includes a restriction portion engaging the board and restricting a movement of the electromagnet in a direction where the iron piece moves away from the electromagnet.

Abstract: An electromagnetic actuator includes a rotor rotatable within a predetermined angular range, a magnetizing coil, and a yoke having an arcuate surface facing the rotor, and first and second magnetic-pole parts that have mutually different magnetic poles upon energizing the coil. The rotor includes a magnetized rotor part defining the outer peripheral surface of the rotor and magnetized to have different magnetic poles, a non-magnetized driving pin rotatable with the magnetized rotor part, and a protrusion part protruding radially from the rotor and facing the first or second magnetic-pole part while being magnetized to have the same magnetic pole as the outer peripheral surface of the rotor. The surface of the rotor that faces the yoke and that exerts a magnetic action is increased due to the inclusion of the protrusion part, and hence a desired maintaining force and driving torque can be obtained.
