Abstract:
According to an embodiment, an exposure device has first and second eccentric cams. The first eccentric cam has an eccentric shape that supports a first mirror support point located near the center on one end side in a longitudinal direction of a mirror and varies a distance between a first rotary shaft and the first mirror support point in correspondence to rotation around the first rotary shaft. The second eccentric cam has an eccentric shape that supports a second mirror support point of two support points located on the other end side in the longitudinal direction of the mirror and varies a distance between a rotary shaft and the second mirror support point in correspondence to rotation around the rotary shaft.
