Lens barrel
A lens barrel includes an electric contact fixed to a mount, a first substrate disposed between a fixed barrel and the mount, a second substrate connected to the first substrate and the electric contact while forming a folded portion, and disposed so as to overlap the first substrate when viewed from an optical axis direction, a plurality of first elastic members held by the fixed barrel and configured to position and hold the first substrate in a direction orthogonal to an optical axis, and a second elastic member held by the fixed barrel and disposed between the fixed barrel and the first substrate. The first substrate is urged toward the fixed barrel in the optical axis direction by a force from the folded portion, and contacts the second elastic member on a surface on a side of the fixed barrel of the first substrate.
1. A lens barrel comprising:
a fixed barrel;
a mount attached to the fixed barrel;
an electric contact fixed to the mount;
a first substrate disposed between the fixed barrel and the mount;
a second substrate connected to the first substrate and the electric contact while forming a folded portion, and disposed so as to overlap the first substrate when viewed from an optical axis direction;
a plurality of first elastic members held by the first substrate and configured to position and hold the first substrate in a direction orthogonal to an optical axis; and
a second elastic member held by the fixed barrel and disposed between the fixed barrel and the first substrate,
wherein the first substrate is urged toward the fixed barrel in the optical axis direction by a force from the folded portion, and contacts the second elastic member on a surface of the first substrate on a side facing the fixed barrel.
2. The lens barrel according to claim 1 , wherein the second substrate is connected to the first substrate on a surface opposite to the surface of the first substrate on the side facing the fixed barrel.
3. The lens barrel according to claim 1 , wherein the second substrate is connected to the first substrate on the surface of the first substrate on the side facing the fixed barrel.
4. The lens barrel according to claim 1 , further comprising a gyro sensor or an acceleration sensor mounted on the first substrate.
5. The lens barrel according to claim 1 , wherein the second substrate overlaps the second elastic member when viewed from the optical axis direction.
6. The lens barrel according to claim 1 , wherein the folded portion overlaps the mount or the electric contact when viewed from the optical axis direction.
7. The lens barrel according to claim 1 , wherein the second elastic member is disposed within a first angle range of ±60 degrees with respect to a straight line connecting a center of a connector between the first substrate and the second substrate and a center of the optical axis.
8. The lens barrel according to claim 1 , wherein a straight line connecting a center of the folded portion and a center of the optical axis is located in a first angle range of ±60 degrees with respect to a straight line connecting a center of a connector between the first substrate and the second substrate and the center of the optical axis.
9. The lens barrel according to claim 7 , wherein the plurality of first elastic members are disposed within a second angle range of 240 degrees outside the first angle range.
10. The lens barrel according to claim 1 , wherein the first substrate contacts the second elastic member only on the surface of the first substrate on the side facing the fixed barrel.
