Document Type and Number:
Japanese Patent JP2017067939
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a focal plane shutter for an imaging device and the imaging device that can prevent blades from moving from a prescribed stop position due to an impact or the like.SOLUTION: When a rotor 12 is at an open position and a closed position of blades 3, an inner peripheral edge of a connection lever for transmitting driving force of the rotor 12 to the blades 3 is made nearly a right angle to a straight line going through the rotation center of the rotor 12 and a drive pin 12b in addition to detent torque generated by magnetic poles of a permanent magnet of the rotor 12 and magnetic poles of magnetic pole portions 13a and 13b of a yoke 13, allowing the blades 3 to be kept at a stop position without fail.SELECTED DRAWING: Figure 5
