Image printing apparatus

An image printing apparatus including means for conveying a printing medium and means for scanning a carriage to move across the direction in which the printing medium is conveyed by the printing medium conveying means, the carriage being attached to a printing head for printing an image on the printing medium, said image printing apparatus comprising:

• a scale disposed along the direction of scanning of the carriage by the scanning means;
• a sensor for detecting the position of the carriage relative to said scale, said sensor being mounted on the carriage opposing said scale;
• and
• a cover for covering said sensor and at least a part of said scale adjoining said sensor, said cover being provided with a guide portion for guiding said scale to a predetermined position with respect to said sensor, and said guide portion opposing said scale so that said guide portion interposes the portion of said scale corresponding to the reading center of said sensor.
