<p>PROBLEM TO BE SOLVED: To provide a camera which does not generate mirror moving noise and prevents deterioration in the photographic accuracy even at the time of photographing in the nonoperating state of a shake correcting device by locking the mirror when the shake correcting device is in the nonoperating state. SOLUTION: The power supply of this video camera is turned on, a current is caused to flow through a coil 60, a locking member 58 is moved up by the generated magnetic force and an upper magnet 52 attracts the member 58. When a position detection sensor 56 detects it, a current of the coil 60 is cut off, the attrition state of the member 58 by the magnet 52 is maintained, a mirror 22 is fixed and the mirror moving preventing device is operated. In the mean time, when the operation of the mirror moving preventing device is suspended at the time of photographing and a shake correction mode is selected, a reverse current flows through the coil 60, the member 58 is moved downward and attracted by a lower magnet 54, and the sensor 56 detects it, cuts off the current and maintains the attracted state. A control part controls the current of a coil 36, controls the strength of the magnetic force between a movable member 38 and a magnet 22, moves the mirror 22, moved the mirror 22, cancels swinging and gets a precise image.</p> |
