Abstract
An optical scanner includes a third f-theta lens, an eccentric cam, an attaching portion, a first supporting member, a second supporting member and a spring. A distance between a face opposed to the first side-face of the third f-theta lens in the first supporting member and a face opposed to the second side-face of the third f-theta lens in the second supporting member is set to be longer than a distance of the third f-theta lens in its lateral direction. The spring is disposed opposed to the first side-face or the second side-face, and presses the third f-theta lens so that the third f-theta lens is in contact with the eccentric cam and either of the first supporting member and the second supporting member.
