Abstract: An image input-output apparatus includes a housing which is internally provided with a common transfer path. Further, the housing internally incorporates a transfer mechanism for selectively transferring a document and a recording paper along the common transfer path, a combination of an image reading light source and an image sensor for optically reading an image of the document moving along the common transfer path, and a printing unit for printing an image on the recording paper moving along the common transfer path. The width of the recording paper may be detected by a combination of a width detecting light source and the image sensor.

Abstract: When a desired stitch pattern is selected by the operator, stitch pattern data representing the desired stitch pattern and image data representing the image of the stitch pattern to be projected on a workpiece are stored temporarily in a RAM. When the push button of a frame shifting switch is depressed, an embroidery frame holding the workpiece is shifted from a stitching area to an image projecting area. The image of the stitch pattern can be projected without being obstructed by the needle bar, the needle and the presser foot on the workpiece held by the embroidery frame placed in the image projecting area, so that the operator is able to confirm the stitch pattern to be formed easily and correctly. A projector projects the full-sized image of the stitch pattern on the basis of the image data read from the RAM on the workpiece held by the embroidery frame.
