Abstract
An optical decoder and a multi-functional printer using the same are provided. The optical decoder includes a directional light source, a light guide bar and a light receiving unit. The light guide bar disposed on a light-emitting side of the directional light source has multiple scales. The light receiving unit is disposed on a side of the light guide bar, wherein the directional light source and the light receiving unit are disposed on different sides of the light guide bar. The light receiving unit is used to move along the light guide bar and read the scales of the light guide bar. The overall volume of a multi-functional printer can be reduced by applying the optical decoder therein.
