By using the technique of operator block,the matrix form of the almost sharp quantum effect on an infinite dimensional Hilbert spaces is given.Furthermore,combined with the theory of the generalized inverses,the condition of existence and representation of the generalized inverses of the almost sharp quantum effect is studied.
