Abstract
PURPOSE:To prevent occurrence of measuring errors even when measuring elements are moved at a high speed by providing a coarse scale contact group and a fine scale contact group on a contact base, and displaying the output from a pair of brushes for both contact groups which are moved with the measuring elements through a counter circuit. CONSTITUTION:The brush contacts 24a and 24ba are concurrently slidden with the movement of the measuring elements on the coarse scale contact group 20 and the fine contact group 22, respectively. A coarse measured signal 100a and a fine measured signal 100b are inputted to counters 30a and 30b and counted. At this time, the counter 30b is reset at every time the pulse of the coarse measured signal 100a is generated. The upper digits and the lower digits of the measured values are digitally displayed on a upper digit display 32a and a lower digit display 32b. Therefore measuring errors do not occur even when the measuring element is moved at the high speed.
