Signal Recording/Reproducing Apparatus

Abstract

A data recording/reproducing apparatus includes a first power source unit which generates necessary electric power signals from a commercial power source, and a second power source unit which generates a necessary electric power signal from the commercial power source. When a user issues an instruction to interrupt the operation of the power source of the apparatus, the generation of the electric power signal of the first power source unit is stopped, and the electric power is supplied to at least two of a control unit for controlling switching of operation states of the apparatus, a reception unit for receiving a manipulation instruction, and a display unit for displaying thereon data relating to the operation state from the second power source unit.

1 . A data recording/reproducing apparatus including a recording signal processing unit; a received signal processing unit; a unit for driving a recording medium; a reception unit for receiving a manipulation instruction issued from a user; a control unit for controlling switching of operation states of said apparatus in response to the instruction; and a display unit for displaying thereon the data relating to the operation state of said apparatus, said apparatus comprising: 
 a first power source unit for generating a necessary electric power signal from a commercial power source; a first switching unit for switching start and stop of the generation of the electric power signal of said first power source unit; a second power source unit for generating a necessary electric power signal from said commercial power source; and a second switching unit for switching start and stop of the generation of the electric power signal of said second power source;    wherein when a user issues an instruction to interrupt the operation of the power source of said apparatus, the generation of the electric power signal of said first power source unit is stopped, and the electric power is supplied to at least two of said control unit for controlling the switching of the operation states of said apparatus, said reception unit for receiving a manipulation instruction, and said display unit for displaying thereon the data relating to the operation state from said second power source unit.    
   
   
       2 . A data recording/reproducing apparatus according to  claim 1 , wherein said first power source unit is for a heavy load, while said second power source unit is for a light load.  
   
   
       3 . A data recording/reproducing apparatus including: 
 a recording signal processing unit;    a received signal processing unit;    a unit for driving a recording medium;    a reception unit for receiving a manipulation instruction issued from a user;    a control unit for controlling switching of operation states of said apparatus in response to the instruction; and    a display unit for displaying thereon the data relating to the operation state of the apparatus, said apparatus comprising:    a first power source unit for generating a necessary electric power signal from a commercial power source;    a first switching unit for switching start and stop of the generation of the electric power signal of said first power source unit;    a second power source unit for generating a necessary electric power signal from said commercial power source; and    a second switching unit for switching start and stop of the generation of the electric power signal of said second power source;    wherein said recording signal processing unit, said reproduced signal processing unit and said unit for driving a recording medium are all supplied with the electric power from said first power source unit;    at least two of said control unit for controlling the switching of the operation states of said apparatus, said reception unit for receiving a manipulation instruction, and said display unit for displaying thereon the data relating to the operation state are all supplied with the electric power from said second power source unit; and    when a user issues an instruction to interrupt the operation of the power source of said apparatus, the generation of the electric signal of said first power source unit is stopped.
