A pair of shift registers (25, 26) are used to retain information as to the location of recorded signals denoting ends of dictation segments and location of instructions. As rewound tape is transcribed a third shift register (27) creates a shutter comprising contiguous lighted segments which moves to the right during a transcription operation. Control circuitry (67, 62) allow shifting of the registers containing the end of segment and instruction marks to occur only when the tape is rewound past the farthest point reached during a previous rewinding operation. A display for a dictation recorder is also shown wherein a pair of up down counters (130, 145) control numerical displays representing the total length of tape used (20) and the length of the present dictation segment (21). Apparatus which is sensitive to rewinding of the tape into a previous dictation segment (165, 28) is used to control the present segment counter. The present segment counter may be selectively made (169, 177, 150) to begin counting again upon either entry into the next dictation segment encountered during forward advance or the segment in which dictation was occuring when the rewound operation was initiated. ## Claims ### Claim 1 In a dictation recording system including a dictate station, said dictate station including means for generating an end signal and a means for recording on a record medium said end signal delimiting the end of a segment of dictation, motion signal means for providing a motion signal in response to an increment of said record medium moving past a predetermined reference point, a transport for selectively moving said record medium in a forward direction and a reverse direction, and an end mark detector for detecting a previously-recorded end signal and providing a detected end signal, an improved display apparatus for said dictation station for maintaining a visual representation of the location of said reference point within the present one of a plurality of segments of dictation on said record medium, comprising: direction detecting means for providing a forward signal when said record medium is moving in said forward direction and a reverse signal when said record medium is moving in said reverse direction; up/down counting means responsive to said motion signal, said forward signal, and said reverse signal, said counting means being incremented upon each concurrence of said motion signal and said forward signal and decremented upon each concurrence of said motion signal and said reverse signal; display means connected to said counting means for displaying the count maintained by said counting means as said visual representation of the location of said reference point within the present dictation segment; and control means responsive to said detected end signal and said reverse signal for rendering said counting means unresponsive to increment and decrement upon the exit from said present one of a plurality of segments of dictation when moving said record medium in said reverse direction, said inhibit means being further responsive to said detected end signal and said forward signal for rendering said counting means responsive to increment and decrement upon the reentry of said present one of said plurality of segments of dictation when moving said record medium in said forward direction, whereby said display means is rendered inoperative to display the location of said reference point upon the exit in the reverse direction from the present segment of dictation and until the return in the forward directon to the present segment. ### Claim 2 (depends on 1) The improved display apparatus of claim 1, further comprising clearing means associated with said counting means for setting said counting means to zero in response to each concurrence of said detected end signal and said forward signal.
