Abstract

PURPOSE:To make it possible to indicate the direction without being affected by the turbulance of magnetic field vibrations and the like, by detecting a direction changing angle by means of an angular sensor and calculating a signal proportional to the direction changing angle. CONSTITUTION:An angle theta between the reference direction and the advancing direction is detected by the angular sensor 1. A traveling distance meter 2 detects a traveling distance S by the revolution number of a wheel. By an arithmetic circuit 3, tantheta is calculated using the output theta of the angular sensor 1, and a product S. tantheta between the output tantheta of the arithmetic circuit 3 and the output S of the traveling distance meter 2 is made in a multiplying circuit 4. The direction change signal is obtained by making said product signal 1/h, in a dividing circuit 5, and said signal is indicated on a direction indicating device 8 by controlling said signal with an indicating device 6.
