  Deformation of Ising Hamiltonian by means of replacing a site spin $s_i$ by
$s_i^q$ and statistics generalization with help of the substituting deformed
probability $p_i^q$ instead of $p_i$ are studied jointly within mean--field
scheme. Such deformed model is shown to be related to the phase transition of
the second order with unusual set of critical indices depending essentially on
the deformation parameter $q$. Scaling relations turn out to be invariant with
respect to the deformation.
