PROBLEM TO BE SOLVED: To realize long drive, small-size and weight reduction of a transportable type device, by exchangeably placing a translucent type of a map sheet on a photo-receiving face of a solar battery module for a driving power source to indicate a present position located by a position-measuring means on the map sheet. SOLUTION: A holder 3 has a position-measuring means including a GPS receiver, a control circuit of the receiver, an operation panel 6 in a holder body 3a, and an indicating means including a LED array 5. Also, a present latitude and longitude information is obtained by the GPS receiver, and predetermined LEDs in the LED array 5 are lighted based upon the information. The LED array 5 is constituted of each two columns of vertical and horizontal LED arrays respectively arranged. In each of the two columns of vertical and horizontal LED arrays, virtual lines, where the lighted LEDs in vertical and horizontal columns are respectively connected, are a parallel of latitude and a longitude line at a present position. Accordingly, the present position is a cross point of both virtual lines on a map. |
