Description

[Detailed description of the invention] The present invention relates to an automatic editing control device, and by providing an eject switch for ejecting the cassette tapes of each of the playback machine and the editing machine, it is possible to save the trouble of ejecting the cassette tapes. An object of the present invention is to provide an automatic editing control device that does not require waiting for the completion of an ejection operation when replacing a cassette tape.

3/4-inch U-standard video tape recorders have a high relative speed between the video head and the tape, have a wide video signal recording track width, and record with a video guard band, so they are faster than regular home videos. The image quality is high. Further, the U standard video tape recorder has a rotary erase head, a blanking switch, and also has a capstan servo and reel servo system. For this reason, assembly editing is performed in which each cut is recorded in random order on a cassette tape, and then a desired cut is selected and played from this already recorded cassette tape and recorded in order on the master cassette tape. It is possible to perform editing such as insert editing in which a reproduced signal from a recorded cassette tape is recorded at an intermediate position of the cassette tape with high image quality and high precision.

Conventionally, the video tape recorder that plays the recorded cassette tape and the video tape recorder that edits and records the master cassette tape are controlled remotely, and the editing positions of the recorded cassette tape and the master cassette tape are selected and registered. ,
There is an automatic editing control device that automatically edits and records a reproduced signal at a registered position on a recorded cassette tape at a registered position on a master cassette tape.

This automatic editing control device can remotely control operations such as recording, playback, stop, pause/freeze, fast forward, rewind, search, etc. of the video tape recorder for playback and edit recording. For some reason, there was no eject switch for ejecting the cassette tape. but,
For example, when selecting a desired cut from a plurality of cassette tapes, the number of eject operations is large, and for each eject operation, it is necessary to operate the eject switch of the video tape recorder located far away from the automatic editing control device. The disadvantage was that it was time-consuming.
