Abstract

PROBLEM TO BE SOLVED: To confirm the reproducing time of a video signal and an audio signal by inputting a time data, from a clock hand moving means to store or read the data to or from the memory when the running condition detecting means detects the 'reproducing condition' and by inputting a recording information from a recording information output means to store or read information to the memory when the 'recording condition' is detected. SOLUTION: A control means 107 stores, when the running condition of a tape type recording medium output from a running condition detecting means 102 is 'recording condition', the recording information regarding video signal and audio signal such as recording speed/recording channel input from the recording information output means 101 and recording information such as recording start time/recording end time/recording data input from a clock hand moving means 104 to a memory 105. When the tape type recording medium is in the reproducing mode in the recording/reproducing means 100, a tape number management means 103 reads the tape number of the tape type recording medium which is reproduced currently by the recording/reproducing means 100 and displays such number to a control means 107 to display it on the display unit 106.

The control unit 107 controls the display unit 106 to display the contents of the record information, and the display unit 106 displays the record information, so that the user can check the record information. An example of the display is as shown in FIG.

When the tape-shaped recording medium is in the reproducing state in the recording / reproducing section 100, the traveling state detecting section 1
02 detects that the running state is the "reproduction state" and outputs it to the control unit 107. When information indicating that the recording / reproducing unit 100 is in the “reproducing state” is input from the running state detecting unit 102, the control unit 107 inputs the tape number being reproduced from the tape number managing unit 103, and based on the tape number, Then, the recording information stored in the memory unit 105 is read out. Further, the control unit 107 instructs the display unit 106 to

When the tape-shaped recording medium is reproduced, the control section stores and reads out the time data input from the timepiece movement section in the memory section so that the data is displayed on the display section. An object of the present invention is to provide an information signal recording / reproducing apparatus which can display and enable a user to confirm the reproduction time of a video signal and an audio signal.
