A card reader may include a card conveying mechanism; a guide; a magnetic head; a positioning member to position the card relative to the magnetic head; and a shutter. The positioning member may include a card abutting part to abut a third direction end of the card; and a card support part to contact a first direction side of the card. A distance between the card abutting part and a third direction end of the guide is shorter than a width in the short-side direction of the card. When the shutter has closed, a fourth direction end of the shutter is disposed on a first direction side of the guide. When the shutter has opened the opening, the shutter is disposed on the first direction side of the guide. The third direction end of the card may be guided to the card support part by the shutter.
