Abstract: Provided is a self-propelled reading device to read cards more reliably. Each of the cards includes a first end part configured to be adjacent to another card in a predetermined direction; a second end part configured to be on the opposite side of the first end part and adjacent to another card different from the first end part; and a surface printed with a pattern in which are coded coordinates indicating a positional relation relative to a reference line extended in the predetermined direction indicative of a region in which a self-propelled device is to travel. Each of the first and the second end parts has a positioning part regulating how the other card adjacent to the end part is to be placed. The positioning parts and the reference line have a predetermined positional relation therebetween.
