<p>PURPOSE:To make possible carrying use by achieving a smaller size and a saving of power. CONSTITUTION:An angle of rotation of an antenna 1 is detected to be stored into an antenna angle register 7. A distance measuring circuit 15 calculates a distance data based upon a reflected radio wave from a target after transmission from the antenna 1 to be stored into an address corresponding to a memory circuit 16. A display device 24 performs a display with a liquid crystal to achieve a saving of power. The antenna 1 is turned manually to eliminate a motor. Various circuits are integrated and thus, portability is made possible with a saving of power and a smaller size.</p> |
