but i don't know which ic can counter for encoder??
i am using 74LS47 for encoder counters?but, it didn't work??

What exactly is an 'encoder counter?'

My guess would be that he has a quadrature encoder output, and wants to count up for rotation in one direction, and count down for rotation in the other direction. Is that correct, novrisa?

How many bits of counting do you need? Do you know how to design the logic to take the quadrature encoder outputs (two signals, correct?), and use those to make an up/down signal and a counter clock signal? Then, do you know of counter ICs that have an up/down count control input?
