There is provided an image scanner including (a) an image sensor, (b) a lens for focusing images onto the image sensor, (c) a reflecting mirror for directing images of an object to the image sensor through the lens, and (d) a driver for rotating the reflecting mirror. The reflecting mirror has a first width located closer to the lens and a second width located remoter from the lens than the first width, both of the first and second widths extending in parallel with the image sensor. The first width is designed to be smaller than the second width. The reflecting mirror is preferably trapezoidal. The driver is within a difference between the first and second widths so that the driver does not exist beyond the second width of the reflecting mirror. Since the driver is arranged not to exist beyond a width of the reflecting mirror, it is possible to make the image sensor smaller in a size as a whole.
