Abstract: A wire winding device which uses a large-sized supply bobbin, which has a large capacity and a large diameter, to highly precisely suppress a variation in tension which variation occurs when a coil is formed by winding a wire material at high speed with the wire material aligned with a winding frame. Rotation (the number of rotation, and timing) of the supply bobbin relative to rotation of the coil is controlled based on the difference between the amount of take-up of the wire material taken up on the winding frame side and the amount of pay-out of the wire material paid out from the supply bobbin, and the control is performed such that the amount of the take-up and the amount of the pay-out agree with each other every moment. This can highly precisely suppress a variation in tension even if there are large differences between inertia of and the diameters of the coil and the supply bobbin.

Abstract: Disclosed is a printer including a paper feeder for accommodating a rolled paper to be pulled out and recorded thereon. The feeder has a container section to set the roll, in which first and second support walls are arranged to rotatably support the roll. While paper from the roil is taken out, a contact force produced by the roll against the first support wall is kept larger than that in a stationary state, and a contact force produced by the roll against second support wall is kept smaller than that in the stationary state. A friction coefficient between the second support wall and the roll is larger than one between first support wall and the roll, the roll being in slidable contact with the first and second support walls. Therefore, when the recording is started, an impact force to the roll can be alleviated, resulting in reducing unevenness in image in a feeding direction of the paper.
