Raman scattering spectra of mixed crystals of cuprous halides are measured. The observed behaviours of the optic phonon modes are well accounted for by the modified random element isodisplacement (MREI) model, and the mode types are determined as the one-mode type for CuBr1-xIx and the two-mode type for CuCl1-xBrx and CuCl1-xIx. The existing criterion for the mode type is valid in predicting the observed results in CuCl1-xIx and CuBr1-xIx, but for CuCl1-xBrx, more sophisticated model appears to be needed. The experimental local mode frequencies due to chlorine impurity in CuBr and CuI are in a reasonable agreement with the calculated values by the linear chain model. As for the gap mode in CuCl, the interpretation is not straightforward because of the complexity associated with the appearance of the double TO-like ($\beta$, $\gamma$) mode.
