Abstract:
1. An input-output device comprising: a storage unit that registers: a link table that associates and registers a dot code which is at least one of a code value and a coordinate value with predetermined information; and the predetermined information, an optical reading unit that reads a dot pattern formed on a medium surface; a processing unit that analyzes the dot pattern from image information of the dot pattern read by the optical reading unit and converts the dot pattern into the dot code; a connection unit that wiredly or wirelessly connects an information processing device; a connection recognition unit that recognizes whether or not a connection with the information processing device exists; and a control unit that controls operation of the optical reading unit, the processing unit, the connection unit, the connection recognition unit or operation based on the predetermined information, wherein the control unit switches operation based on whether or not the connection recognition unit recognizes a connection between the connection unit and the information processing device, when the connection recognition unit recognizes a connection between the connection unit and the information processing device, the control unit transmits at least one of the dot code and the predetermined information that is associated and registered with the dot code through the connection unit to the information processing device, and when the connection recognition unit does not recognize a connection between the connection unit and the information processing device, the control unit causes the input-output device alone to perform the processing corresponding to the predetermined information.
