  • Patent number: 4894731
    Abstract: In a camera integrated with a VTR, a hotographing method by use of a self timer is disclosed. This method comprises the steps of: setting a recording standby state; supplying to a display section a repetitive signal for allowing the display section to be alternately repetitively lit on and off by operating a self timer operating element; supplying a light-on signal to the display section when a predetermined time has passed to thereby light on the display section, supplying an operation signal to the VTR section, cancelling the camera recording standby state, and thereby starting a recording; and stopping the supply of the light-on signal to the display section after the elapse of a predetermined time after the recording was started to thereby light off the display section, stopping the supply of the operation signal to the display section, and thereby returning to the camera recording standby state.

  • Patent number: 4707749
    Abstract: The invention relates to a control signal recording apparatus of a magnetic recording/reproducing apparatus for recording a video signal on a video track on a magnetic tape and reproducing the recorded video signal. There is provided control signal recording means for inserting a cue signal and a desired address signal as two kinds of pulse signals having different duty ratios onto a control track and the head portion of each video information. Due to this, various kinds of control signals such as cue signal, address signal, and the like can be easily recorded, erased, rewritten, and the like. Also, the address signal can be inserted after the recorded cue signal. Therefore, the editing and head search of the tape can be easily performed.
