  • Publication number: 20210231967
    Abstract: The present disclosure provides an optical unit with shake correction function capable of preventing a thrust receiving member, which fixes a sphere, from falling off from the movable body in an optical axis direction. According to some embodiments of the present disclosure, a thrust receiving member to which a first sphere is fixed is held by a holding portion formed of the cutout recess provided in a fixed body. A bottom wall surface of the holding portion makes contact with a bent plate portion of the thrust receiving member from ?Z direction side. Further, locked surface parts provided on a pair of side wall surfaces of a holding portion make contact, from +Z direction side, with a pair of locking plate portions protruding from a bent plate portion in circumferential direction in the thrust receiving member.

  • Patent number: 11052010
    Abstract: A training device suppresses unintended operation of an operation rod when executing an operation mode in which operation of the operation rod is controlled based on a force applied to the operation rod. The training device includes the operation rod, a motor, a force detector, a rotation information output sensor, a first command calculator, and a force corrector. The operation rod moves a limb. The motor operates the operation rod in a direction of degree of freedom. The force detector detects a force component and outputs a force component signal. The rotation information output sensor detects an operation position of the operation rod in a corresponding direction of degree of freedom. The force corrector calculates a corrected force component value based on operation positions of the operation rod and force component signal. The first command calculator calculates a first motor control command based on the corrected force component value.
