摘要： PROBLEM TO BE SOLVED: To obtain the video signal recorder that conducts backup recording with a simple operation without the need for any external video signal distributer or the like by giving a same video signal as that recorded by one selected video signal recording means to at least one other video signal recording means. SOLUTION: A component input changeover circuit 8 and a composite input changeover circuit 9 select and output a signal at a 1st component video signal input terminal 1 and a 1st composite video signal input terminal 2 respectively under the control of an input changeover control circuit 12. Furthermore, the input changeover control circuit 12 controls a changeover device 14 to give a control signal outputted from a 1st signal type changeover control circuit 5 to a 2nd signal type changeover circuit 10. Thus, a 1st video signal recording circuit 4 and a 2nd video signal recording circuit 11 receive same signals and record the signals onto a recording medium. Thus, it is not required to provide an external video signal distributer or the like.
