徴とする媒体引き寄せ機構。[Scope of Claim for Utility Model Registration] A clamp lever having a presser at the tip, a moving mechanism for moving the position of the rear end of the clamp lever, and a mechanism for opening the tip of the clamp lever depending on the position of the rear end of the clamp lever. In the medium pulling mechanism, which has a cam mechanism to control and a drive source to drive the moving mechanism, and which moves the rear end of the clamp lever to sandwich the medium between the pressers and pull it toward the reference surface, the completion of drawing is detected. a detection sensor; a motor whose rotational speed is adjustable as a drive source for the moving mechanism; and if the sensor does not detect completion of the pulling operation after the first pulling operation, the rotational speed of the motor is switched and the clamp lever is moved. 1. A medium attracting mechanism comprising: a control means for controlling the attracting speed of the medium to be switched and the attracting operation to be performed again.
