Abstract
The built-in multidriver device for a camera zoom lens has an independent driver for each lens of a zoom lens kit, and each driver is integrated into the lens mount. A housing positions each independent driver accordingly. The driver devices each include coil stators, magnetic rotors, fixed solenoids, inner solenoid bases, and limited units. The coil stators are placed in the housing, and the magnetic rotors are connected to the fixed solenoids. The inner solenoid bases are connected to the fixed solenoids, and the inner solenoid bases are limited and turned by the limiting units. When the magnetic rotor is turned by the magnetic induction of the coil stators, the fixed solenoid turns in the inner solenoid base, and the inner solenoid base is limited by the limiting unit. The inner solenoid base is moved axially, and the lenses inside are driven to zoom independently.
