PROBLEM TO BE SOLVED: To provide an exposure device which does not cause trouble such as disconnection, interference with other parts and the leakage of electricity caused in the conventional technique to perform feed to the exposure lamp of a scanner part through a cable, etc., which does not cause shake and image blur and which is equipped with a feeding means for the exposure lamp. SOLUTION: A lamp mirror unit 2 constituted by integrating the exposure lamp 3 with a mirror 8 is made to travel along an original on a contact glass 1, and light carrying an original image is reflected by the mirror 8 and transmitted to an exposure part. As for power supply to the lamp 3, the lamp 3 is placed on feed rods 4 juxtaposed in a state where contact pieces 5 and 5 fixed on both sides of the unit 2 are set as a supporting point, whereby a contact is secured and the feed is realized. A groove fit to the cylindrical shape of the rod 4 is provided in order to stabilize the action of the contact piece 5 sliding in traveling, and the rod 4 is held between the contact piece 5 and a pulley 6 between which a tension spring 7 is laid.
