Abstract
An auto-zooming device for a camera includes a lens, a first position device, a second position device, a magnet and a coil. The second position device is connected to the lens and engages with the first position device. The magnet is connected to the second position device. The coil is disposed around the magnet. When a current flows into the coil, the current induces a magnetic force to rotate the magnet. Meanwhile, the second position device rotates with the magnet and causes the lens to move forward or backward accordingly.
