摘要：PROBLEM TO BE SOLVED: To provide a return route guiding device that can be portably used by a user, and has a simple structure without a GPS function surely guide a use to a correct return route and can surely guide him/her to a correct route. SOLUTION: This device is provided with a display device 3 and an operation part 4 on the front of a portable main body 2, as well as an image sensing device 5 on its upper side. A positional signal recording an identification name and a positional information and having a two-dimensional code as well is provided at several key places on the street of a shopping mall. The positional information includes coordinate data of the key places and their neighbouring place information. A user selects a menu of return route guide and executes it, and furthermore he/she senses in sequence the positional signals provided on the route from a starting point to a destination point by the image-sensing device 5, so that the decoded positional data are stored in sequence in order in the data storing part of the main body 2. When the user directs the information processing part of the main body 2 to indicate the guiding of return route, it displays the positional information stored in the data storing part on the display device 3 in the reverse order of inputting.
