ABSTRACT:
A printing apparatus comprising: an elongate platen; a guide member extending parallel to the platen; a carriage slidably movable on the guide member; a printing head mounted on the carriage; an image reading device including an image-reading portion for reading images on a recording medium on the platen, the image-reading portion being movable between a reading position adjacent to the recording medium, and a retracted position spaced from the reading position in a direction away from the recording medium; and a device for engagement of the image reading device with the carriage, to permit the image reading device to move together with the carriage. The image reading device may be supported pivotally by the guide member in the form of a rod. The carriage may have a stopper abutable on the image reading device to determine the reading position of the image-reading portion. The apparatus may further comprise a member for checking optical sensitivity of the image reading device. This checking member has a reflector which is selectively placed in an operative position opposite to the image-reading portion, and an inoperative position misaligned with the image-reading position.
