A printer configured to perform printing on recording paper includes a body and a lid. The body includes a holder configured to accommodate the recording paper. The lid is attached to the body to be opened and closed relative to the body. An opening is formed at the bottom of the holder to allow attachment of a function module to the bottom of the holder.

A winding and unwinding system includes at least two winding rollers, a roll-changing device, a sensing device, a measuring device, and a controller. The roll-changing device can drive at least two winding rollers to sequentially move to a set position, where the winding roller located at the set position can wind a strip material. The sensing device emits an in-place signal when the winding roller located at the set position rotates one circle. The measuring device is configured to measure a traveling length of the strip material. The controller, upon receiving the in-place signal, determines a winding radius of the winding roller located at the set position based on the traveling length measured by the measuring device, and when the winding radius reaches a preset threshold, controls the roll-changing device to drive another winding roller to move to the set position and get in contact with the strip material.

In an image forming apparatus that the present invention is concerning to, rolled paper is conveyed in a forward conveyance direction for a predetermined period of time, when it is detected that an amount of the rolled paper rolled around a core pipe equals a predetermined amount or less. On the basis of the detection result, a CPU determines the rolled state of the rolled paper with respect to the core pipe and conveys the rolled paper in the forward conveyance direction or a reverse conveyance direction according to the rolled state.
