Claims

[Scope of utility model registration request]

a recording time setting circuit that outputs a first signal corresponding to the recording time of the tape when the tape is loaded during recording; a timer that operates simultaneously with the start of recording; and a timer that outputs the first signal from the recording time setting circuit and the timer. a counter that calculates the remaining tape amount time based on the output and outputs a second signal corresponding to the remaining tape amount time; and a counter that outputs the second signal from the counter when the tape is attached and during the space pause during recording. When writing to or reproducing a tape, a magnetic head is used to read out the second signal written on the tape, and the remaining amount of the tape is determined by the second signal from the counter and the second signal read by the magnetic head. What is claimed is: 1. A tape remaining amount time display device comprising: a display device for displaying time;
