Abstract

Claims (26)

1. An adjusting device for positioning an object, the adjusting device comprising:

a base which is configured to move an object that is connectable to the base in a connected state along a path of motion in a position-controlled manner; and

a supply line for conveying energy and/or signal transmission to and/or from the base,

wherein the supply line is coupled to the base in a reversibly detachable manner,

wherein the object is a lens; and

the base comprises:

a drive unit that is configured to receive the lens and to move the lens along the path of motion; and

a position sensor that is configured to detect the position of the lens along the path of motion,

wherein the path of motion runs along a direction of focus of the lens.

2. The adjusting device according to claim 1 , wherein the adjusting device further comprises:

a coupling device, via which the supply line is coupled to the base in the reversibly detachable manner,

the coupling device including a first coupling section that is fixedly connected to the base and a second coupling section that is fixedly connected to the supply line.

3. The adjusting device according to claim 2 , wherein a coupling axis, along which the first and the second coupling section are selectively coupled and/or decoupled, is oriented to be perpendicular to the path of motion.

4. The adjusting device according to claim 2 , wherein a dividing plane, along which the first and the second coupling sections are divided, is oriented to be parallel to the path of motion.

5. The adjusting device according to claim 2 , wherein the coupling device is arranged on a surface of the base facing away from the path of motion.

6. The adjusting device according to claim 2 , wherein the first coupling section is connected to the base by a cable for the energy and/or signal transmission.

7. The adjusting device according to claim 2 , wherein the first and the second coupling section are coupled to each other magnetically.

8. The adjusting device according to claim 7 , wherein at least one of the first and second coupling sections comprises at least one permanent magnet or at least one electromagnet.

9. The adjusting device according to claim 2 , wherein the first and second coupling sections are couplable to one another by frictional engagement or a positive-fit connection.

10. The adjusting device according to claim 9 , wherein one of the first and second coupling sections is configured as a female coupling section and the other of the first coupling sections is configured as a male coupling section.

11. The adjusting device according to claim 10 , wherein the female coupling section is configured as a connector receptacle with depressions and/or projections and the male coupling section is configured as a connector with depressions and/or projections.

12. The adjusting device according to claim 2 , wherein contacts for the energy and/or signal transmission are arranged in a circular shape in both coupling sections.

13. The adjusting device according to claim 2 , wherein at least a portion of the first coupling section is configured to be rotatable and lockable at different rotational positions.

14. The adjusting device according to claim 1 , wherein the drive unit is a piezoelectric motor.

15. The adjusting device according to claim 1 , wherein the supply line comprises several separate conductors for the energy and/or signal transmission in a common jacket.

16. The adjusting device according to claim 1 , wherein the supply line comprises a connector for connection to an external device.
