ABSTRACT:
A transmission mechanism of an image scanner with adjustable resolution is disclosed. The transmission device is driven by a step motor to move a carriage to perform a scanning operation at a selected speed The transmission device includes a transmission control set switched between a first and a second transmission states in response to a command for changing a moving speed of the carriage, and driven by the step motor to output a transmission power; a first transmission set of a first deceleration ratio, coupled with the transmission control set to receive the transmission power from the transmission control set in the first transmission state, and providing the transmission power for the carriage to have the carriage move at a first speed; and a second transmission set of a second deceleration ratio different from the first deceleration ratio, coupled with the transmission control set to receive the transmission power from the transmission control set in the second transmission state, and providing the transmission power for the carriage to have the carriage move at a second speed.
