Translocation dynamics of an active semi-flexible polymer through a nano-pore into a rigid two dimensional circular nano-container has been studied by using Langevin dynamics simulations. The results show that the force exponent beta, for regime of small nano-container radius, i.e. R<>Rg the asymptotic value of the force exponent is beta = -0.93. The force exponent is defined by the scaling form of the average translocation time where Fsp is the self-propelling force. Moreover, using the definition of the turning number (number of net turns of the polymer configuration) for the polymer inside the cavity, it has been found that at the end of translocation process for small value of R and in the strong force limit the polymer configuration is more regular than the case in which the value of R is large or the force is weak.
