<p>Manually operated first, second and third command entry switches (13, 14, 15) are provided for respectively generating first, second and third command signals. In response to the first command signal a controller (9) successively recalls portions of received messages from a memory (10) in a first sequence and causes the recalled portions to be successively displayed. The controller responds to the second command signal by successively recalling starting portions of the messages in a second sequence and causing the recalled starting portions to be successively displayed. To simplify back scrolling operations, the controller responds to the third command signal by successively recalling the portions of the messages in a direction opposite to the first sequence if the portion being displayed at the moment the third command signal is generated is not a starting portion or successively recalling the starting portions of the messages in a direction opposite to the second sequence if the portion being displayed at the moment the third command signal is generated is a starting portion.</p> |
