Abstract
PURPOSE: To correct the errors of a pattern pitch, by measuring a period or the speed of rotary pulses under a stationary, rotary condition, by memorizing the period or the speed in response to pattern number that the pulses generate, and by reading the period or the speed when measuring variation.
CONSTITUTION: A switch 13 is closed under 1 stationary, rotary condition, and counting value corresponding to a rotary pulse period is memorized to addresses 1, 2...every time rotary pulses successively reach a pattern period memory circuit 14 while using a location where timing pulses are generated as an address 0. Under a condition that variation is measured the reciprocal value of rotary pulses F is computed 10 in order while being input to a multiplication circuit 15 every calculation, the rotary pulses simultaneously read the pattern period memory circuit 14, the period is multiplied by the pattern period measured under the stationary condition by the same pattern as a pattern that the rotary pulses generate, and rotary variation value is measured in a shape of ratio to speed value under the stationary condition.
