ンタ装置のカバー開閉機構。 The cover body disposed on the top of the device body is opened and closed by the combined torsional moment of multiple torsion springs, and the torsion springs other than those at both ends are double torsion type torsion springs that act only from the initial to middle opening/closing angle. By using , the combined torsional moment at the beginning of opening/closing is made larger than the opening/closing moment of the cover body during synchronization, the combined torsional moment during the middle stage of opening/closing is made smaller than the opening/closing moment of the cover body during synchronization, and the combined torsional moment at the end of opening/closing is A cover opening/closing mechanism for a printer device characterized in that the moment is made larger than the opening/closing moment of a cover body during synchronization.
