A manual type image scanner rolls on X-direction and Y-direction rollers which support the scanner for translation in X and Y-directions, respectively. The scanner scans a surface while translated in the Y-direction. The X-direction roller is positioned on the scanner so that it is remote from a scanned surface when the scanner is supported on the Y-direction rollers. The position of the X-roller is such that the scanner can be supported on the X-direction rollers by tilting the scanner about one end of the Y-direction rollers until the X-direction roller contacts the surface and further tilting the scanner to lift the Y-direction rollers off the surface. Movements of the X-direction and Y-direction rollers are registered by encoders so that an area wider than an image width of the scanner can be scanned by consecutively scanning adjacent paths by making alternating traversals in the X- and Y-directions.
