Abstract
Provided is a drive apparatus including: a first drive unit group including first drive units, each for generating a magnetic field to drive a first object provided with a first lens and magnet in an optical axis direction; and a second drive unit group including second drive units, each for generating a magnetic field to drive a second object provided with a second lens and magnet in the direction. Each of the first and second drive units includes a first and second terminal connected via a clock and data signal line to a master controlling the drive unit as a slave. In at least one of the first drive units, the first and second terminals are respectively forward-connected to the clock and data signal lines. In at least one of the second drive units, the second and first terminals are respectively reverse-connected to the clock and data signal lines.
