Driving mechanism and optical equipment

1. A driving mechanism of an imaging element, comprising:

a fixed member;

a moving member at which the imaging element is mounted and that is movable relative to the fixed member;

a first driving member that is movable in a first direction, the first driving member being a separate member with respect to the fixed member;

a second driving member that is movable in the first direction, the second driving member being movable independently of the first driving member, the second driving member being a separate member with respect to the fixed member;

a third driving member that is movable in the first direction, the third driving member being movable independently of the first driving member and the second driving member;

a fourth driving member that is movable in the first direction, the fourth driving member being movable independently of the first driving member, the second driving member and the third driving member;

a first abutting portion that is provided at the moving member and abuts against the first driving member and the second driving member; and

a second abutting portion that is provided at the moving member and abuts against the third driving member and the fourth driving member, wherein

the moving member is moved by driving force of the first driving member and the second driving member abutting against the first abutting portion and by driving force of the third driving member and the fourth driving member abutting against the second abutting portion.

2. The driving mechanism according to claim 1 , wherein,

the first abutting portion and the second abutting portion include pins protruding in a direction orthogonal to a direction in which the moving member moves.

3. The driving mechanism according to claim 1 , wherein

the first driving member includes a first inclined face that engages with the first abutting portion,

the second driving member includes a second inclined face that is inclined at a different angle from the first inclined face and engages with the first abutting portion,

the third driving member includes a third inclined face that engages with the second abutting portion, and

the fourth driving member includes a fourth inclined face that is inclined at a different angle from the third inclined face and engages with the second abutting portion.

4. The driving mechanism according to claim 3 , further comprising

an urging member that urges the moving member in a second direction which is orthogonal to the first direction, wherein

the first inclined face and the second inclined face are inclined at substantially the same angle in opposite directions with respect to the second direction, and

the third inclined face and the fourth inclined face are inclined at substantially the same angle in opposite directions with respect to the second direction.

5. The driving mechanism according to claim 4 , wherein,

an inclination angle of the third inclined face is the same as an inclination angle of the first inclined face, and

an inclination angle of the fourth inclined face is the same as an inclination angle of the second inclined face.

6. The driving mechanism according to claim 1 ,

further comprising a guide member that guides movement in the first direction of the first driving member, the second driving member, the third driving member and the fourth driving member relative to the fixed member.

7. The driving mechanism according to claim 1 ,

further comprising a calculation section that calculates a relative movement position of the moving member with respect to a fixed position, from a position of the first driving member, a position of the second driving member, a position of the third driving member and a position of the fourth driving member.

8. Optical equipment comprising the driving mechanism according to claim 1 .
