Abstract: PURPOSE: A PTZ camera driving device is provided to precisely control a PTZ camera without vibration by preventing torque compensation and backlash of a stepper motor. CONSTITUTION: A PTZ(Pan, Tilt, Zoom) camera driving device includes a photographing unit(100), a tilt compensation module(200), and a stepper motor. If the stepper motor is rotated in the counterclockwise direction, a pinion gear(210) is rotated in the counterclockwise direction to move a rack gear(220) to the right direction in which a dual coil spring(230) is compressed. If the stepper motor is rotated in the clockwise direction, the pinion gear is rotated in the clockwise direction to move to the left direction in which a dual coil spring is compressed. [Reference numerals] (AA) Left direction; (BB) Right direction

Abstract translation: 目的：提供PTZ摄像机驱动装置，通过防止步进电机的转矩补偿和反向间隙，精确控制PTZ摄像机，无振动。 构成：PTZ（平移，倾斜，变焦）摄像机驱动装置包括拍摄单元（100），倾斜补偿模块（200）和步进马达。 如果步进电动机沿逆时针方向旋转，则小齿轮（210）沿逆时针方向转动，使齿条（220）向双螺旋弹簧（230）被压缩的右方向移动。 如果步进电动机沿顺时针方向旋转，则小齿轮沿顺时针方向旋转以向双方螺旋弹簧压缩的左方向移动。 （附图标记）（AA）左方向; （BB）右方向
