Charmed (and bottom) hypernuclei are studied in the quark-meson coupling (QMC) model. This completes systematic studies of charmed (Λ_c^+, Σ_c, Ξ_c), and Λ_b hypernuclei in the QMC model. Effects of the Pauli blocking due to the underlying quark structure of baryons, and the Σ_c N - Λ_c N channel coupling are phenomenologically taken into account at the hadronic level in the same way as those included for strange hypernuclei. Our results suggest that the Σ_c^++ and Ξ_c^+ hypernuclei are very

A detailed analysis is also made about the phenomenologically introduced Pauli blocking and channel coupling effects for the Σ_c^0 hypernuclei.
