发明名称 Answering machine arrangement
摘要 An answering machine arrangement includes a recording medium for recording a message from outside with a passcode being previously recorded in a particular area of the recording medium, a device for reading the passcode from the recording medium when a "play" button is depressed and a controller for judging if the passcode read from the recording medium is identical to a passcode input by an operator, such that the message recorded in the recording medium is played back only when these passcodes are identical to each other. The secrecy of the recording message is maintained. Upon changing the passcode, all messages are erased automatically.
