Display including variable mode for a record and/or playback device |
摘要 |
A variable mode numerical display for a record/playback device normally displays a numerical count representing the present position of the record medium used with that device and is operable to interrupt this normal display so as to display the number of a message that was last-recorded or that is in position for playback or to display the number of an instruction that was last-recorded or that has been reached. Also, a bar graph display is comprised of plural visual display elements which are selectively energized as a function of the interval that separates successive pulses that are generated in conjunction with the movement of the record medium. The variable mode and bar graph displays are controlled by a processor.
