To prevent loss of guiding function during operation by providing an electronical stick having a mannual power generator for supplying power to a transmission circuit when a battery for an electronic information body is dead.

In the normal operation, power is supplied to a transmission and receiption circuit part from a charged battery. When the battery comes to be dead after a long time use, it is detected by a life condition detector, and before the battery stops its power supply comletely, then an voice information is outputted as an alarm of dead battery from an earphone 20. With the receiption, a user is to charge the battery, but when the receiption is made at a place where no battery charging can not performed, the user rotates a lever 18 of a mannual power generator 17 to supply power to the circuit part. Accordingly, the user can obtain information from an electronic information body after the battery is dead, and thereby can move safely to a place where the battery charging is made.
