Loading unit, for data writing and/or reading device, having improved reliability in loading/ejecting operation and having function enabling easy ejection

摘要

An ejecting mechanism ejects the data writing and/or reading device, which has been loaded on the loading unit, from the loading unit. A preventing mechanism prevents the data writing and/or reading device from either being loaded on or being ejected from the loading device while power is active in the loading unit. A connecting/disconnecting mechanism connects the data writing and/or reading device to an external apparatus when the data writing and/or reading device is loaded on the loading unit. The mechanism also disconnects the data writing and/or reading device from the external apparatus when the data writing and/or reading device is ejected from the loading unit. A signal may be transferred between the external apparatus and the data writing and/or reading device and the external apparatus supplies power to the data writing and/or reading device while the data writing and/or reading device is loaded on the loading unit. A signal may be neither transferred between the external apparatus and the data writing and/or reading device nor may the external apparatus supply power to the data writing and/or reading device while the data writing and/or reading device is ejected from the loading unit.
