Abstract
A contact point type measuring device being equipped with contact point type encoder having scale contact points and brushes to supply pulse type measured signals, a counter circuit and a display section of measured value, such device comprising the scale contact points consisted of larger scale contact points arranged in a required distance and of smaller scale contact points dividing the larger scale contact point distance at a certain required pitch, the counter circuit including a larger scale counter counting larger scale measured signals obtained from the larger scale contact points and a smaller scale counter counting small scale measured signals obtained from the smaller scale contact points and resetting such counted value by the larger scale measured signals, and the display section of measured value including an upper figure displayer displaying counted value of the larger scale counter and a lower figure displayer displaying counted value of the lower scale counter, and parts of such device being manufactured with extreme ease and accuracy by mass production.
