• an embroidery unit main body including the X-transfer mechanism and the Y-transfer mechanism and attached detachably to the sewing machine bed and having a main portion, when attached to the sewing machine bed, is located below an upper surface thereof, the main portion being provided with the X-transfer mechanism and the Y-transfer mechanism;
• a Y-carriage mechanism provided on the Y-transfer mechanism so as to protrude above the main portion and moved in the X-direction in a position further left from a left end of the free arm;
• and
• an auxiliary lid attached detachably to an upper surface of the embroidery unit main body so as to cover the Y-carriage mechanism such that an upper surface of the auxiliary lid and an upper surface of the sewing machine bed is substantially at level.

An embroidery unit detachably attached to a sewing machine bed provided with a cloth feed mechanism including a feed dog having an X-transfer mechanism and a Y-transfer mechanism that carries an embroidery frame in an X-direction parallel to a lengthwise direction of the sewing machine and a Y-direction perpendicular to the X-direction, the embroidery unit comprising:

• an embroidery unit main body attached to the sewing machine bed either in an embroidery attachment position for performing embroidery sewing with an embroidery frame or in a normal sewing attachment position for performing a sewing operation by the feed dog of the cloth feed mechanism;
• and
• a switch member switching the feed dog between a feed dog operating position where cloth feeding is allowed and a feed dog non-operating position where cloth feeding is disallowed,
• wherein when the embroidery unit main body is attached to the embroidery attachment position, the embroidery unit main body operates the switch member so that the feed dog is switched to the feed dog non-operating position, and when the embroidery unit main body is attached to the normal sewing attachment position, the embroidery unit main body is disallowed to operate the switch member such that the feed dog is positioned in the feed dog operation position.
