Abstract: The sensor magnets have, on a side facing the attraction plate: an S1 magnetized portion magnetized to an S pole; an N2 magnetized portion located at a position adjacent to the S1 magnetized portion in an L1 direction, and magnetized to an N pole; an S3 magnetized portion located at a position adjacent to the N2 magnetized portion in an L2 direction intersecting the L1 direction, and magnetized to the S pole; and an N4 magnetized portion located at a position adjacent to the S3 magnetized portion in an L3 direction intersecting the L2 direction and adjacent to the S1 magnetized portion, and magnetized to the N pole. The attraction plate overlaps at least part of the S1 magnetized portion, the N2 magnetized portion, the S3 magnetized portion, and the N4 magnetized portion, when viewed in an optical axis direction.

Abstract: An image stabilization mechanism includes: a sensor holder unit that holds an image sensor; a rear frame; a front frame; a first ball; a second ball; and a cylinder unit that presses the first ball against the sensor holder unit. The cylinder unit has a cylinder provided on the rear frame so that its axial direction is parallel to an optical axis direction, a piston movably disposed in the cylinder, and a spring that urges the piston toward the sensor holder unit. The first ball is disposed between an end surface of the piston and the sensor holder unit.

Abstract: The imaging apparatus has a single shooting mode and a continuous shooting mode, and includes: an imaging element configured to generate image data; a mechanical shutter configured to control exposure of the imaging element; a charge block including a driving mechanism configured to drive the mechanical shutter and a motor configured to provide a driving force for the driving mechanism, and a control section configured to control the charge block. The control section performs a charging operation for charging the driving mechanism by causing the motor to rotate in a capturing operation, performs the charging operation in a first time period in a case where the imaging apparatus is in the continuous shooting mode, and performs the charging operation in a second time period which is longer than the first time period in a case where the imaging apparatus is in the single shooting mode.
