Abstract
An LED printer includes a lower body frame, an upper body frame being detachably mounted on the lower body frame, an LED frame with a lever mounted on the upper body frame for supporting an LED head array, a spring connected between a right end portion of the LED frame and the upper body frame, and a process unit with an upper leading end for mounting a photo-sensitive drum. The LED head array is mounted beneath the right end portion of the LED frame, and the upper leading end pushes the lever when the process unit is installed inside the upper body frame so that a distance between the photo-sensitive drum and the LED head array is properly maintained. The LED frame is pivoted on a hinge to an inoperative position by a recovering force of a spring connected between the upper body frame and the LED frame.
