Abstract

PURPOSE:To continuously measure a change in a car height and to enhance durability and reliability, by fixing one of a combination of a light source with a unidimensional position detecting element and a slit shutter to a car body member and moving the other one in connection with the up-and-down displacement of a wheel support member with respect to the car body member. CONSTITUTION:A unidimensional position detecting element 3 is constituted so that the photocurrent generated by the incident light from a light source 1 is split so as to be inversely proportional to the distance from the position of the incident light to the electrodes at both terminals of the element 3. Therefore, by taking the sum and difference of the photocurrents I1, I2 taken out from both electrodes using an operation circuit 4, the position of the incident light can be calculated. Then, a slit shutter 2 is moved from the position of a drawing (a) to the position of a drawing (b) and, with this movement, a slit 2a is allowed to exceed the center of the element 3 to reach the position opposed to the under side. Whereupon, the magnitude relation of the current I1, I2 from both electrodes is reversed by the movement of the position of the incident light to the element 3 but the moving quantity of the position of the incident light can be continuously calculated by the operation of the circuit 4.
