An object is to acquire the precise width dimension of a medium that is loaded into a paper feed section of a printing apparatus and that has a size other than the standard sizes. The printing apparatus includes *a paper feed section into which media are loaded, a regulating guide provided movably for regulating positional shifting of the media in close proximity to the edge of the loaded media, and a position sensor capable of detecting any given position of the regulating guide. Further, in order to detect the position of the regulating guide, as the position sensor, there are provided: a position detection pattern provided on the paper feed section side, an optical sensor that is provided on the regulating guide side, that has a light-emitting section emitting light toward the position detection pattern and a light-receiving section receiving light reflected from the position detection pattern, and that outputs a signal corresponding to the intensity of the light received by the light-receiving section, and a detection section for detecting the position of the regulating guide based on the signal outputted from the optical sensor. In addition, there is provided a sensor for detecting the presence of media within a predetermined distance from the regulating guide.
