  • Conveying device for adjusting scanning resolution
    Patent number: 7534183
    Abstract: A conveying device for adjusting scanning resolution includes a planetary gear transmission a belt and a scanning device. The planetary gear transmission has a base, a first stepping motor and a second stepping motor. A first motor gear drives a sun gear. A second motor gear drives a purl gear. Four planetary gears are received in a hole of the purl gear. The planetary gears are driven by the inner gear and the upper gear at the same time, so the planetary gears rotate around a positioning axle of the sun gear at a speed of half the speed difference of the inner gear and the upper gear. Then a planetary frame rotates along with the planetary gears. A belt wheel mounted on the planetary frame drives the belt with a scanning device to move.
