Abstract: PROBLEM TO BE SOLVED: To properly position a medium handler and a magazine slot when the medium handler takes the medium out of and into the magazine in an automatic medium exchanger. SOLUTION: A guiding system is provided with a guiding target 200 and an imaging device 102 attached on a medium handler. The guiding target 200 is arranged at a predetermined position in the range of an automatic medium exchanger 300. The imaging device 102 produces an image of the guiding target 20 and the automatic medium exchanger 300 analyzes the image and determines the relative position of the medium handler against the guiding target 200. The guiding target 200 has a right triangle shape and the imaging device 102 produces the image of the target consisting of scanning lines perpendicular to the base. By dividing the length of the scanning lines between the base and the hypotenuse by the tangent of given vertical angle, the cross point of the scanning line and the base, i.e., the distance from the vertical angle is calculated.  Based on the distance, the medium handler can be guided.
