Claims

[Scope of utility model registration request]

There is a tape remaining time detector that detects the time remaining on the loaded cassette tape and outputs a first signal, and a second signal that calculates the recording time when set to automatic recording mode.
a recording time calculation circuit that outputs a signal; and a recording time calculation circuit that is supplied with the first and second signals and calculates both signals when the remaining tape time in the set tape running mode is less than the recording time. An arithmetic circuit that outputs a third signal, a first alarm device that issues an alarm when supplied with the third signal, and a device that determines whether or not recording is possible at a lower speed than the set tape running mode and allows recording. A tape recorder configured to include a discrimination circuit that outputs a fourth signal at certain times, and a second alarm that issues an alarm when supplied with the fourth signal.
