Patent ID: 7623941

Claim:
A method for adjusting a relative position between an outputting device and an image sensing device of a laser engraver, comprising the following steps: a. forming a marked point on a non-working piece by the outputting device, moving the outputting device to a center of the marked point and recording a position of the center of the marked point; b. moving the image sensing device to the center of the marked point; c. recording a position point that the outputting device is located after the outputting device being concurrently moved according to the motion of the image sensing device in step “b”; and d. calculating a distance between the center of the marked point recorded in step “a” and the position point of the outputting device recorded in step “c” to obtain the precise distance between the image sensing device and the outputting device, wherein the outputting device and the image sensing device are both connected to a frame to synchronize movement of the outputting device and the image sensing device.
