Claims

[Scope of Claim for Utility Model Registration] A device for press-bonding a printing head to a platen, comprising: a swingable head holding member that holds the printing head; a swinging member that swings separately from the head holding member; , a cam rotationally driven by a stepping motor, an elastic member that connects the head holding member or a part that swings integrally with the swinging member and urges them in a direction to sandwich the cam, and the position of the cam. When the cam rotates in a direction in which the head holding member or a part that swings integrally with the cam moves away from the central axis of rotation of the cam, the head holding member moves in a direction in which the printing head moves away from the platen. When the cam rotates in the direction in which the swinging member moves away from the central axis of rotation of the cam, the head holding member rotates in the direction in which the print head is pressed against the platen due to the action of the elastic body, and the printing is completed. After the head is pressed against the platen, the head holding member or a part that swings together with the head is separated from the cam, and the print head is pressed against the platen by an elastic member.
