Abstract
PURPOSE:To prevent the abnormal operation during the use of the VTR, by performing the alarm operation when the power source voltage is lowered to a prescribed value or less and by stopping automatically the operation of the VTR after a prescribed time. CONSTITUTION:If voltage B of power source 1 is lowered to a detection voltage value while the VTR is used by power source 1 such as a battery, signal D is generated in voltage detecting circuit 7, and delay time generating circuit 9 generates signal E according to this generation of signal D and supplies signal E to alarm circuit 11. Alarm circuit 11 generates alarm signal G to report a fear of the occurrence of the abnormal operation in the VTR. When a prescribed time passes without the stop operation, delay time generating circuit 9 stops generating output signal E, and STOP command generating circuit 10 generates signal F at the rise of signal E to stop the VTR by system logic circuit 3, thereby preventing the occurrence of the abnormal operation.
