Abstract
An embroidery frame driving device includes: a base plate firmly fixed to an X-Y driving unit of the embroidery frame driving device; a fixation arm provided on the base plate; an attachment/detachment cam; a removing link; a coupling link; and an embroidery frame. The embroidery frame is slid against the base plate to rotate the attachment/detachment cam and the fixation arm through pressing of a pressing part of a fixation part to press and fix one end of the fixation arm to a fixation groove of the fixation part in attachment of the embroidery frame. The removing link is operated to rotate the coupling link and the attachment/detachment cam to rotate the fixation arm and release pressing and fixation of the fixation groove of the fixation part by the one end of the fixation arm in detachment of the embroidery frame.
