<p>PURPOSE:To simplify the circuit constitution or control of a system and to exchange a recording medium in a short time by providing a terminal to which a command to eject the recording medium is inputted, and ejecting the recording medium by the command inputted from the terminal. CONSTITUTION:The medium ejection start up terminals 17 of medium driving devices 12 and 13 are connected to the medium ejection start up terminals 19 of a control part 14b in a medium exchange device 14 via signal lines 15 and 16, respectively. And the medium exchange device 14 instructs the ejection of the recording medium to the medium driving devices 12 and 13 via the medium ejection start up terminals 17 and 19 and the signal lines 15 and 16. Thereby, it is not required to control the ejection of the recording medium for the medium driving device 12 and 13 by a system controller 11. In such a way, it is possible to simplify the circuit constitution or the control of the device even when an interface of universal application is used, and also, to shorten a time to exchange the recording medium.</p> |
