項ないし(2)項記載のデイジタル信号記録装置。[Claims for Utility Model Registration] (1) An analog input recording mode in which a recording source is D/A converted to an analog signal, and the digital signal obtained by A/D conversion is digitally recorded. , a digital signal recording device having a digital input recording mode in which a digital signal as a recording source is digitally recorded without converting it into an analog signal; a system control unit that detects whether or not a digital recording prohibition condition exists and controls the system; and an input signal selection switch that is controlled by the system control unit and selects either the analog or digital input recording mode. A digital signal recording device comprising: a digital input recording mode is selected preferentially by the input signal selection switch at the time of starting recording. (2) When a digital recording prohibition condition is detected in the system control unit, the input signal selection switch is switched from the digital input recording mode to the analog input recording mode. ) The digital signal recording device according to item 2. (3) The above digital recording prohibition conditions include detection of the digital recording prohibition flag defined in the digital interface format, PCM-I
A utility model characterized in that it uses any one of detecting a digital recording prohibition flag in D, detecting an identification hole formed in a soft tape cassette, detecting a sampling frequency, and detecting a deviation of the sampling frequency of a predetermined value or more. Scope of Registration Claim No. (1)
The digital signal recording device described in paragraphs to (2).
