1. A film scanner for reading an image formed on a film, said film scanner comprising:
an imaging device that senses a part of said image to generate an image signal;
a transport table that supports said film;
a stepper motor that moves said transport table in a predetermined direction, so that said imaging device can sense the whole of said image, said stepper motor being driven in steps; and
an image signal reading processor that reads said image signal in synchronization with movement of said transport table, said image signal reading processor reading at one or both of a first timing where said stepper motor stops at a rotational angle position of a step and a second timing where said stepper motor stops at least at one rotational angle position within a step.
