Abstract
When a memory cassette having semiconductor memory is attached to or detached from a connector mounted on an adapter, the supply of power to the memory cassette through the adapter is switched on or off and an interface signal between the memory cassette and the adapter is rendered active or inactive in response to connection or disconnection between the memory cassette and the adapter. The stored content of the semiconductor memory can be protected against destruction which would otherwise result from application of a power supply voltage upon connection or disconnection between the memory cassette and the adapter.
